Description

FIELD OF THE INVENTION

The present invention relates to an electrical plug connector with the features of patent claim 1. The present invention also relates to an electrical plug connection with the features of patent claim 14.

TECHNICAL BACKGROUND

While the two electrical interfaces of a straight electrical connector have a common longitudinal axis, the longitudinal axes of the two electrical interfaces of an angled electrical connector are oriented to one another at a certain angle, preferably at an angle of 90°. Such angled electrical connectors are used in a variety of configurations in which the use of the electrical connection requires a change of direction in the signal routing. Angled plug connections are used, for example, in an electrical connection between two printed circuit boards that are oriented perpendicular to one another or when a cable is routed parallel to the surface of the printed circuit board due to the installation space.

As is well known, if a differential signal is transmitted in an angled connector, two inner conductor contact elements are required for this. If the two inner conductor contact elements each have the same distance between the two interfaces, in particular between their two axial ends, two identical inner conductor contact elements can be guided parallel to one another in the angled plug connector. In addition to the use of identical parts for the two inner conductor contact elements, a simple impedance adjustment of the angled connector for the transmission of a differential high-frequency signal can be achieved. Due to the same lengths of the two inner conductor contact elements, there is no phase offset, or so-called "skewing", of the differential signal along the two inner conductor contact elements. As will be shown below, this does not require a mode conversion differential signal and therefore no increased emission of electromagnetic interference and no reflection of the differential high-frequency signal.

The applications of angled connectors are becoming more and more diverse and with them the arrangement of the two inner conductor contact elements at the two interfaces or at the axial ends of the two inner conductor contact elements. The large number of arrangements of the two inner conductor contact elements at the two interfaces enables a variety of shapes of the inner conductor contact elements between the two interfaces and, as a result, a different quality of impedance matching, a different degree of skewing and a different degree of symmetry of the inner conductor contact elements.

In contrast to the above-mentioned trivial case of identical inner conductor contact elements, no optimum can be achieved in all three criteria of impedance matching, skewing and symmetry for other configurations of the inner conductor contact elements.

SUMMARY OF THE INVENTION

Against this background, the present invention is based on the object of creating a generally valid technical solution for a differential angled connector for all possible arrangements of the inner conductor contact elements at the two interfaces - with the exception of the trivial case mentioned above - with which an overall optimum of the criteria of impedance matching, skewing and symmetry can be achieved.

According to the invention, this object is achieved by an electrical plug connector with the features of patent claim 1 and by an electrical plug connection with the features of patent claim 14.

The knowledge/idea on which the present invention is based is to create an angled differential plug connector with a pair of contact elements, ie with an inner conductor contact element pair, consisting of a first contact element and a second contact element, the distance between which is as small as possible over the entire longitudinal extent Has variance and is preferably constant. Such a design of the two inner conductor contact elements advantageously enables an impedance curve with the lowest possible fluctuations in order to preferably achieve a constant impedance curve.

While the distance between the first and second contact elements is usually constant in a first longitudinal section in which the first interface of the differential angled plug connector is formed and in a second longitudinal section in which the second interface of the differential angled plug connector is formed, The distance between the first and the second contact element in a third longitudinal section formed between them is to be minimized in terms of its variance by a suitable shape of the first and the second contact element.

In this context, it should be noted that the transition between the first and the third longitudinal section of the pair of contact elements and thus the axial end of the first longitudinal section of the two contact elements is located at that axial position of the pair of contact elements at which at least one contact element is formed by a linear formation a curved shape passes over. This applies equivalently to the transition between the second and third longitudinal sections of the pair of contact elements.

In order to minimize the variance of the distance between the two contact elements, the first and second contact elements in the third longitudinal section are about a same axis of rotation, which is referred to below as the first axis of rotation and orthogonal to the longitudinal axis of the first and second contact elements in the first and second Longitudinal section is oriented, bent by an equal angle of rotation, which is referred to below as the first angle of rotation φ ₁ . In addition, the first and the second contact element in the third longitudinal section are each bent in such a way that the longitudinal axes of the first and the second contact element are relative to a further axis of rotation, which is referred to below as the second axis of rotation and runs centrally between the first and the second contact element a further equal angle of rotation, which is referred to below as the second angle of rotation φ ₂ , are shifted in parallel. The second axis of rotation can, as in the discussion of Individual variants of the contact elements are still shown, have a linear course or a curved course.

With the bending of the two contact elements each by a first angle of rotation φ ₁ about the first axis of rotation in the third longitudinal section, the orientation of the longitudinal axes of the first and second contact elements between the first and the second longitudinal section is bridged at the level of the first angle φ ₁ '. The first angle of rotation φ ₁ corresponds to the first angle φ ₁ '. In this way, the basic angularity of the differential angled connector is realized in a plane that is oriented perpendicular to the first axis of rotation.

Preferably, the first angle is 90°, so that a right-angled differential connector can be realized.

With the bending of the two contact elements about the second axis of rotation by a second angle of rotation φ ₂ , a further orientation of a plane, which is spanned by the longitudinal axes of the first and second contact elements in the first longitudinal section and is referred to below as the first plane, becomes the orientation of the first and second contact element in the second longitudinal section at the level of the second angle φ ₂ 'bridged. The second angle of rotation φ ₂ results from subtracting the second angle φ ₂ ′ from an angle of 90°. With the bending of the two contact elements about the second axis of rotation, which runs centrally between the first and second contact elements in the third longitudinal section, at the level of the second angle of rotation φ ₂ , there is therefore an additional tilting of the two contact elements, ie a further angularity of the differential angled plug connector in one further degree of freedom can be achieved. In this context, the center between the first and the second contact element is understood to be the same radial or approximately the same distance between the two contact elements and the second axis of rotation along the entire longitudinal extent of the third longitudinal section.

Preferably, the second angle is 0°, so that the first plane at the first interface is aligned parallel to the longitudinal axes of the first and second contact elements at the second interface. In particular, the bending of the two contact elements around the second axis of rotation significantly expands the variety of arrangements of the two contact elements at the two interfaces and thus the variety of applications of the differential angled plug connector.

Above all, however, the bending of the two contact elements about the second axis of rotation advantageously enables a distance between the two contact elements whose variance is minimized along the third longitudinal section and is preferably constant.

Building on this optimization, a largely constant and preferably constant impedance profile of the differential transmission system in the third longitudinal section can be achieved by appropriately designing the insulator element and the external conductor contact element.

The first and second contact elements can preferably be manufactured in either a stamping or a turning process. However, other manufacturing technologies are also conceivable, such as casting, deep drawing or embossing. The first and second contact elements preferably have a rectangular cross-section after a punching process and a round cross-section after a turning process. In a rarer implementation variant, a round cross-section, in particular a hollow-cylindrical cross-section, can also be obtained using a punching-bending process.

In a preferred embodiment of the contact element pair, the bending of the two contact elements can completely overlap both relative to the first axis of rotation and relative to the second axis of rotation within the third longitudinal section. It is also conceivable to partially overlap the bending of the two contact elements relative to the first axis of rotation and relative to the second axis of rotation within the third longitudinal section. Finally, the bending of the two contact elements relative to the first axis of rotation and relative to the second axis of rotation can be carried out in successive sections of the third longitudinal section.

The longitudinal axes of the first and second contact elements are each between the axial ends of the third longitudinal section (in the case of complete overlap) or between the axial ends of the partial section of the third longitudinal section (in the case of partial overlap) by bending the contact elements about the second axis of rotation of sequential succession) shifted in parallel.

The bending of the two contact elements can take place continuously over the entire longitudinal extent of the third longitudinal section in all three forms - complete overlap, partial overlap and sequential succession. The bending of the two contact elements can be designed as a bending around a bending radius (convex bending or concave bending) or as a bending around two bending radii (S-shaped course from the sequential combination of a concave bending and a convex bending).

Finally, the bending of the two contact elements can also only take place in discrete sections of the third longitudinal section, between which a linearly extending section of the two contact elements is arranged. Particularly in the last case, the two contact elements can be bent in individual discrete sections of the third longitudinal section both relative to the first axis of rotation and at the same time relative to the second axis of rotation. However, it is also conceivable that in individual discrete sections of the third longitudinal section the two contact elements are bent only relative to the first axis of rotation or only relative to the second axis of rotation.

The continuous bending of the two contact elements over the entire third longitudinal section can preferably be achieved via a turning process. On the other hand, bending the two contact elements in discrete sections of the third longitudinal section, which are connected by linear sections of the two contact elements, is more suitable for a punching process.

The two contact elements each have an equal and constant cross section along their entire longitudinal extent. With a view to adjusting the impedance of the electrical connector designed for high-frequency signal transmission, the cross section of the two contact elements can also change in individual sections. This occurs, for example, if, for assembly reasons, the insulator element and the outer conductor contact element have recesses or other irregularities in certain areas of the differential angled plug connector. Finally, special formations, for example locking claws or locking hooks or locking recesses, can be formed at individual points of the two contact elements for locking the contact element with an adjacent insulator element of the electrical plug connector.

Advantageous refinements and further developments result from the further subclaims and from the description with reference to the figures in the drawing.

It is understood that the features mentioned above and those to be explained below can be used not only in the combination specified in each case, but also in other combinations or alone, without departing from the scope of the present invention.

In a preferred embodiment of the differential angled plug connector, the first and second contact elements each have the same electrical length. Typically, the electrical lengths of the first and second contact elements in the first longitudinal section and in the second longitudinal section are each designed to be the same size due to the parallel guidance of the two contact elements in the first and second longitudinal sections. In addition, the electrical length and thus the longitudinal extent of the first and second contact elements in the third longitudinal section is preferably the same size.

The equal longitudinal extent of the two contact elements advantageously enables the use of identical parts for the two contact elements.

In addition, due to the same electrical length of the two contact elements, a phase offset of the differential signal between the two contact elements of the contact element pair, a so-called "skewing", is advantageously avoided. If skewing is avoided in the entire longitudinal extent and in particular in the third longitudinal section of the contact element pair, the relationship between the common mode and the differential mode of the high-frequency electromagnetic wave remains approximately constant and is preferably constant.

Mode conversion caused by skewing and thus radiation of electromagnetic interference radiation and reflection of the high-frequency electromagnetic wave are advantageously avoided. The formation of a deskewing section outside the differential angled connector, i.e. H. a differential signal section with an inverse electrical length, in the case of skewing it can therefore advantageously be omitted.

In order to achieve an equal longitudinal extent of the first and second contact elements during a parallel displacement of the longitudinal axes of the first and second contact elements by bending the first and second contact elements relative to the common second axis of rotation by the same second angle of rotation within the third longitudinal section, it is preferred to have a to form a constant or approximately constant ratio between the parallel displacement of the longitudinal axis and the change in the longitudinal extent for both contact elements over the third longitudinal section.

In order to achieve an equally large longitudinal extent for both contact elements, the slope of the bend can therefore preferably be the same size for both contact elements along the third longitudinal section. However, a special case is also conceivable in which in individual sections of the two contact elements within the third longitudinal section there is no parallel displacement of the longitudinal axes, ie no bend, but rather a linear course of the two contact elements parallel to the second axis of rotation. Furthermore, are

Partial sections of the two contact elements are possible without bending the contact elements, in which a linear course of the two contact elements is not formed parallel to the second axis of rotation. Finally, partial sections of the contact elements within the third longitudinal section are also possible, in which the ratio between the parallel displacement of the longitudinal axis and the change in the longitudinal extension is different for both contact elements, but the summed changes in the longitudinal extension for both contact elements are the same in the entire third longitudinal section.

In a further preferred embodiment of the electrical plug connector, the first and second contact elements in the third longitudinal section are each bent relative to the first axis of rotation by the first angle of rotation with the same bending radius. By bending the two contact elements relative to the same axis of rotation, by the same angle of rotation and with the same radius of curvature, an equal electrical length can be achieved for both contact elements in the third longitudinal section.

The bending of the two contact elements in the third longitudinal section relative to the common second axis of rotation by the same second angle of rotation takes place in a further preferred embodiment of the pair of contact elements in such a way that the longitudinal axes of the first and second contact elements are each shifted equally parallel to the second axis of rotation in a first radial direction and are each displaced equally parallel to the second axis of rotation, which is oriented orthogonally to the first radial direction, in a second radial direction. Such a form of bending of the two contact elements about the second axis of rotation in combination with the form that the common second axis of rotation is arranged centrally to the two contact elements makes it technically easiest to achieve an electrical length of the same size for both contact elements.

In a further embodiment of the contact element pair, the bending of the first and second contact elements about the first axis of rotation and the bending of the first and second contact elements about the second axis of rotation take place in different subsections of the third longitudinal section, which follow one another sequentially. Here is the subsection, in in which the two contact elements are each bent relative to a first axis of rotation by the same first angle of rotation, preferably arranged on the second longitudinal section. The subsection, in which the two contact elements are each bent relative to the common second axis of rotation by the same second angle of rotation, is preferably formed between the first longitudinal section and the other subsection of the third longitudinal section.

Depending on the application, the first angle of rotation, by which the first and second contact elements are each bent in the third longitudinal section relative to the first axis of rotation, is in an angular range between 45° and 135°, preferably in an angular range between 70° and 110°, particularly preferably in an angular range between 85° and 95° and is particularly preferably 90°.

The second angle of rotation by which the contact elements in the third longitudinal section are bent relative to the common second axis of rotation, i.e. H. the longitudinal axes of the first and second contact elements are shifted in parallel within the third longitudinal section, is greater than or less than 0°, preferably greater than 45° or less than -45°, particularly preferably greater than 80° or less than -80, depending on the application ° and is particularly preferably ±90°.

Preferably, in the first longitudinal section, in the second longitudinal section and in the third longitudinal section, ie in the entire longitudinal extent between the first and the second interface, a distance between the first and the second contact element is the same size and/or is a diameter of the first and the second Contact element each the same size and constant. If the outer conductor contact element and the insulator element, which electrically insulates the first and second contact elements from the outer conductor contact element, also have a homogeneity along the entire longitudinal extent between the first and the second interface, then a constant and thus adapted impedance profile is present over the entire longitudinal extent of the angled differential Connector realized. The homogeneity of the insulator element is, for example, through a uniform dielectric material and through a homogeneous distribution of the dielectric material of the insulator between the external conductor contact element and the (inner conductor) contact element pair is realized over the entire longitudinal extent of the connector. The homogeneity of the outer conductor contact element is achieved by a constant inner diameter over the entire longitudinal extent of the connector.

Because of the mountability of the first and second contact elements, the insulator element and the outer conductor element each have recesses in certain longitudinal sections of the angled differential plug connector, which cause an undesirable shift in the impedance. To adapt the impedance, in such longitudinal sections, for example, the distance between the first and second contact elements must be reduced accordingly and/or the diameter of the first and second contact elements must be increased accordingly.

In a further preferred embodiment of the pair of contact elements according to the invention, the first and second contact elements each have the same extension in the third longitudinal section in a direction of the longitudinal axes of the first and second contact elements in the first longitudinal section. The entire longitudinal extent of the two contact elements from the transition between the second and third longitudinal sections and the axial end of the first longitudinal section is therefore the same size. The longitudinal extent of the two contact elements from the transition between the second and third longitudinal sections and the axial end of the second longitudinal section is also the same size. Thus, the transition between the second and the third longitudinal section of the contact elements represents the angle apex of the differential angle plug, while the extension of the two contact elements from the transition between the second and the third longitudinal section to the axial ends of the first and the second longitudinal section respectively represents the two angle legs of the differential angle connector.

A second plane, which is spanned by the longitudinal axes of the first and second contact elements at the second interface, can have the same orientation to a plane which is spanned by the longitudinal axes of the first and second contact elements at the axial end of the third longitudinal section facing the second interface is stretched. This level is referred to below as the third level.

However, it is also conceivable that the second plane is oriented at a third angle to the third plane that is different from 0°. In this case, a fourth longitudinal section of the first and second contact elements is formed between the second and third longitudinal sections. In the fourth longitudinal axis section, the first and second contact elements are each bent in such a way that, with the same longitudinal extent of the first and second contact elements, the longitudinal axes of the first and second contact elements are relative to a third axis of rotation, which in the fourth longitudinal section is centered between the first and second contact elements runs, are shifted parallel by a third angle of rotation.

The bending of the two contact elements in the fourth longitudinal section also takes place relative to the common third axis of rotation by the same third angle of rotation, preferably in such a way that the longitudinal axes of the first and second contact elements are each shifted equally parallel to the third axis of rotation in a first radial direction and in each case in a second radial direction to the third axis of rotation, which is oriented orthogonally to the first radial direction, are shifted equally parallel. Such a form of bending of the two contact elements about the third axis of rotation in combination with the form that the common third axis of rotation is arranged centrally to the two contact elements enables the simplest implementation
an equal electrical length for both contact elements in the fourth longitudinal section.

The third angle of rotation, which corresponds to the third angle between the second plane and the third plane, is to be interpreted equivalent to the second angle of rotation:
The third angle of rotation is greater than or less than 0°, is preferably greater than 45° or less than -45°, is particularly preferably greater than 80° and less than -80° and is most preferably ±90°.

In a preferred application of the angled differential connector, the first interface is set up to contact a mating electrical connector and the second interface is set up to contact a circuit board. Alternatively, it is also conceivable that the first and second interfaces are each set up to contact a different circuit board. The angled differential connector can also be designed as a cable connector or as a housing connector. Here, the first interface is set up to contact an electrical mating connector, and the second interface is set up to contact a cable or a contacting device in a housing. Finally, the angled differential plug connector can also be designed as an adapter, in which the first and second interfaces are each set up to contact a different electrical mating plug connector.

The invention also covers an electrical plug connection, which includes the electrical plug connector and an associated electrical mating plug connector. All previously and subsequently disclosed features, illustrated features and claimed features for the electrical plug connector also apply equivalently to the electrical plug connection and vice versa.

The electrical mating connector has a mating contact element pair with a first and a second mating contact element. The first and second mating contact elements preferably each have a longitudinal extension with the same electrical length, which are guided parallel to one another. A straight differential electrical mating connector is conceivable. Preferably, the differential electrical mating connector is designed to be angled, so that the first and second mating contact elements are each bent at a fourth angle, preferably at 90° each, with the same radius of curvature.

The first and second mating contact elements thus have a first longitudinal section, a third longitudinal section adjoining the first longitudinal section and a second longitudinal section adjoining the third longitudinal section. The first longitudinal section of the first and second mating contact elements of the mating plug connector are each set up to contact the first and second contact elements of the plug connector at its first interface. In the In the third longitudinal section, the first and second mating contact elements of the mating connector are each bent by the fourth angle. The second longitudinal section of the first and second mating contact elements
forms another interface of the mating connector, for example to another cable.

The above configurations and further developments can be combined with one another in any way, if it makes sense. Further possible refinements, further developments and implementations of the invention also include combinations of features of the invention described previously or below with regard to the exemplary embodiments that are not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

DESCRIPTION OF EMBODIMENTS

The differential angled connector according to the invention is described in all its exemplary embodiments below:
The differential angled connector 1 is preferably designed as a circuit board connector and at its first interface 2 according to Figures 9A to 9C with a corresponding mating contact element pair of a differential mating connector 5 and at its second interface 4 according to Figures 1A to 1E connected to a differential signal line pair on a circuit board 3. Alternatively, the differential angled connector can also connect differential signal line pairs on two circuit boards or differential signal conductors of a cable with a corresponding mating contact element pair of a differential mating connector. All configurations of a differential electrical connection are conceivable, in which differential contacts, differential contact elements, differential signal lines and the like of two connection partners are oriented at an angle to one another.

For this purpose, the differential angled plug connector 1 has a pair of contact elements 6 with a first contact element 7 ₁ and a second contact element 7 ₂ , which, as can be seen from the synopsis of the exploded view in Fig. 1B and the cross-sectional representation in Fig. 1C results in each case extending between the first interface 2 and the second interface 4. The first contact element 7 ₁ and the second contact element 7 ₂ are guided within the differential angled plug connector 1 in an insulator element 8 in such a way that, on the one hand, they are spaced apart from one another in an electrically insulated manner and, on the other hand, they are each spaced apart from an external conductor contact element 9 in an electrically insulated manner. The external conductor contact element 9 can be the metallic connector housing or an external conductor contact element integrated in a dielectric connector housing. In order to have a good shielding effect and the best possible guidance To achieve an electromagnetic wave between the outer conductor contact element 8 and the contact element pair 6 serving as a differential inner conductor contact, the outer conductor contact element 9 encloses the insulator element 8 and the contact element pair 6 guided therein as extensively as possible. A differential angled plug connector 1 according to the invention without the formation of an external conductor contact element 8 is not the preferred embodiment of a high-frequency plug connector, but is also covered by the invention.

The first contact element 7 ₁ and the second contact element 7 ₂ are fixed to the insulator element 8 in a positive and non-positive manner, for example via claws formed on the first contact element 7 ₁ and on the second contact element 7 ₂ , respectively. The insulator element 8 is fixed to the outer conductor contact element 9, for example via a press fit.

For assembly reasons, the outer conductor contact element 9 does not completely enclose the insulator element 8 and the insulator element 8 the contact element pair 6 over the entire longitudinal extent of the contact element pair 6. In particular in a central longitudinal section 10 of the contact element pair 6, for example Fig. 1C As can be seen, the first contact element 7 ₁ and the second contact element 7 ₂ are arranged at a distance from one another, but are surrounded by air and not by the dielectric material of the insulator element 8. Since such a change in the dielectric property in the intermediate area between the outer conductor and the two inner conductors represents a change in the impedance curve, with a view to a more balanced impedance curve, for example in the area of the central longitudinal section 10 of the contact element pair 6, the diameter of the first contact element 7 ₁ and the second contact element 7 ₂ is enlarged and/or the distance between the first contact element 7 ₁ and the second contact element 7 ₂ is reduced.

At the second interface 4 of the connector 1, which forms the interface to the circuit board 3, the contact ends of the first contact element 7 ₁ and the second contact element 7 ₂ are inserted into associated inner conductor-side bores 11 of the circuit board 3 and, for example, via a solder connection or a non-positive press connection Contact surfaces on the inner wall of the bores on the inner conductor side 11 electrically and mechanically connected. Several pins 12 formed on the outer conductor contact element 9, preferably pins 12 each formed on the four corners of the second interface 4 of the plug connector 1, are equivalently inserted into associated outer conductor-side holes 13 of the circuit board 3 and electrically connected to the contact surfaces on the inner wall of the outer conductor-side holes 13 and mechanically connected.

The Fig. 1D represents a side view of the differential angled connector from the rear, ie from a side opposite the plug-in side, from which the individual components of the connector are mounted. From the Fig. 1E shows a side view from the front, ie from the plug-in side, from which the differential angled plug connector is plugged into a corresponding differential mating plug connector. The Figures 1D and 1E serve to further illustrate the individual components of the plug connector, in particular the course of the first contact element 7 ₁ and the second contact element 7 ₂ .

The contact element pair 6 consisting of the first contact element 7 ₁ and the second contact element 7 ₂ has, in all exemplary embodiments, a contact element pair 6 and thus in all exemplary embodiments of a differential angled plug connector 1, as exemplified below using the first exemplary embodiment of the contact element pair 6 according to Figures 2A and 2 B is explained, several longitudinal sections that are connected to each other via certain angular relationships:
The contact element pair 6 points according to Fig. 2A at the first interface 2 a first longitudinal section 14, in which the first and second contact elements 7 ₁ and 7 ₂ are each oriented parallel to one another and have a linear course. At the second interface 4, the contact element pair 6 has a second longitudinal section 15, in which the first and second contact elements 7 ₁ and 7 ₂ are also each oriented parallel to one another and also have a linear course.

Between the first longitudinal section 14 and the second longitudinal section 15, a third longitudinal section 16 is formed in the contact element pair 6, in which the first and second contact elements 7 ₁ and 7 ₂ are each bent relative to a first rotation axis 17 ₁ by a first rotation angle φ ₁ and at the same time the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ are relative are shifted parallel to a second axis of rotation 17 ₂ by bending the first and second contact elements 7 ₁ and 7 ₂ by a second angle of rotation φ ₂ . The first axis of rotation 17 ₁ is oriented for the first and second contact elements 7 ₁ and 7 ₂ each perpendicular to the longitudinal axis L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ in the first and second longitudinal sections 14, 16. The second axis of rotation 17 ₂ runs centrally to the first and second contact elements 7 ₁ and 7 ₂ within the entire longitudinal extent of the third longitudinal section 16.

In addition to the presentation in Fig. 2A the contact element pair 6 between the second longitudinal section 15 and the third longitudinal section 16 has a fourth longitudinal section 18, in which the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ relative to a third axis of rotation 17 ₃ by bending the first and second contact elements 7 ₁ and 7 ₂ are shifted in parallel by a third angle of rotation φ ₃ . The third axis of rotation 17 ₃ runs centrally within the longitudinal extent of the fourth longitudinal section 18 to the first and second contact elements 7 ₁ and 7 ₂ .

The position of the first axis of rotation 17 ₁ , the second axis of rotation 17 ₂ and the third axis of rotation 17 ₃ as well as the orientation of the first angle of rotation φ ₁ , the second angle of rotation φ ₂ and the third angle of rotation φ ₃ in relation to the first and second contact elements 7 ₁ and 7 ₂ go from the following description of all exemplary embodiments of the contact element pair 6 in the Figures 3A to 8C even more clearly:
In a first exemplary embodiment of a contact element pair 6 according to Figures 3A, 3B and 3C the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ are oriented between the first and second longitudinal sections 14 and 15 at a first angle φ ₁ 'of 90 ° to one another. The first and second contact elements 7 ₁ and 7 ₂ are consequently between the first and second longitudinal sections 14 and 15 in a first subsection 16 ₁ of the third longitudinal section 16, which adjoins the second longitudinal section 15, bent relative to a first axis of rotation 17 ₁ by a first angle of rotation φ ₁ at the level of 90 °.

The longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ tension in the first longitudinal section 14 accordingly Fig. 3C a first plane 19 ₁ which is oriented parallel to the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ in the second longitudinal section 15. Thus, the second angle φ ₂ ′ between the first plane 19 ₁ and the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ in the second longitudinal section 15 0 °. Consequently, the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ are formed between the axial ends of a second subsection 16 ₂ of the third longitudinal section 16, which is formed between the first subsection 16 ₁ of the third longitudinal section and the first longitudinal section 14 is, by bending the first and second contact elements 7 ₁ and 7 ₂ relative to a second axis of rotation 17 ₂ , shifted in parallel by a second angle of rotation φ ₂ at the level of 90 °. The first and second contact elements 7 ₁ and 7 ₂ are bent relative to the second axis of rotation 17 ₂ by the second angle of rotation φ ₂ at the level of 90° such that the electrical lengths of the first and second contact elements 7 ₁ and 7 ₂ are within the second Subsection 16 ₂ of the third longitudinal section 16 are the same size. A second plane 19 ₂ , which is spanned by the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ in the second longitudinal section 15, is thus oriented perpendicular to the first plane 19 ₁ , as shown Fig. 3B emerges.

In a second exemplary embodiment of a contact element pair 6 according to Figures 4A, 4B and 4C is the bending of the first and second contact elements 7 ₁ and 7 ₂ relative to a first axis of rotation 17 ₁ by a first angle of rotation φ ₁ at the level of 90 ° and the parallel displacement of the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ by bending the first and second contact elements 7 ₁ and 7 ₂ relative to a second axis of rotation 17 ₂ by a second angle of rotation φ ₂ at the level of 90° simultaneously between the axial ends of the third longitudinal section 16. The bending of the first and second contact elements 7 ₁ and 7 ₂ relative to the second axis of rotation 17 ₂ by the second angle of rotation φ ₂ at the level of 90 ° also takes place in such a way that the electrical lengths of the first and second contact elements 7 ₁ and 7 ₂ within the third longitudinal section 16 are the same size.

The Figures 5A, 5B and 5C show a third exemplary embodiment of a contact element pair 6, in which the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ between the first and second longitudinal sections 14 and 15 at a first angle φ ₁ 'of 120 ° and thus are oriented at an angle other than 90° to each other.

In the Figures 6A, 6B and 6C a fourth exemplary embodiment of a contact element pair 6 is shown, in which the first plane 19 ₁ is not oriented parallel to the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ . The second angle φ ₂ ' between the first plane 19 ₁ and the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ in the second longitudinal section 15 is therefore different from 0 °. The associated second angle of rotation φ ₂ by which the first and second contact elements 7 ₁ and 7 ₂ each move relative to the second axis of rotation 17 ₂ for the parallel displacement of the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ between the axial Ends of the third longitudinal section 16 are bent is therefore also different from 90 °.

In a fifth exemplary embodiment of a contact element pair 6 according to Figures 7A, 7B and 7C the first level 19 ₁ lies in the second level 19 ₂ . In contrast to the first, second, third and fourth exemplary embodiments of a contact element pair 6, in which the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ at the second interface 4 in the second longitudinal section 15 are next to each other and the same distance from the first interface 2 are arranged at a distance, in the fifth exemplary embodiment the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ are arranged one behind the other at the second interface 4 in the second longitudinal section 15 and thus at different distances relative to the first interface 2. The second plane 19 ₂ is oriented pivoted by a third angle φ ₃ to a third plane 19 ₃ , which is oriented through the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ at an axial end pointing towards the second interface 4 of the third longitudinal section 15 is spanned.

In order to move the longitudinal axes L ₁ and L ₂ of the first and second contact elements 7 ₁ and 7 ₂ from a position in the second level 19 ₂ to a position in the third level 19 ₃ in parallel, there is between the second longitudinal section 15 and the third Longitudinal section 16, a fourth longitudinal section 18 of the contact element pair 6 is formed. Between the axial ends of the fourth longitudinal section 18, the first and second contact elements 7 ₁ and 7 ₂ are each bent in such a way that, with the same longitudinal extent of the first and second contact elements 7 ₁ and 7 ₂ , the longitudinal axes L ₁ and L ₂ of the first and second second contact element 7 ₁ and 7 ₂ are displaced in parallel relative to a third axis of rotation 17 ₃ by a third angle of rotation φ ₃ at the height of 90 °. The third axis of rotation 17 ₃ runs in the fourth longitudinal section 18 centrally to the first and second contact elements 7 ₁ and 7 ₂ .

The sixth exemplary embodiment of a contact element pair 6 according to Figures 8A, 8B and 8C shows a rotation of the second level 19 ₂ to the third level 19 ₃ by a third rotation angle φ ₃ , which is 45 ° and is therefore different from 0 ° as in the first to fourth exemplary embodiments and different from 90 ° as in the fifth exemplary embodiment.

From the Figures 9A, 9B and 9C Finally, a differential electrical plug connection 20 with a differential electrical plug connector 1 according to the invention and an associated differential electrical mating plug connector 5 emerge. The differential mating connector 5 can be used as a straight differential mating connector or as in the Figures 9A, 9B and 9C shown as an angled differential mating connector 5.

The angled differential mating connector 5 contains a mating contact element pair 21 with a first mating contact element 22 ₁ and a second mating contact element 22 ₂ , which electrically and mechanically connect the first contact element 7 ₁ and the second contact element 7 ₂ of the angled differential plug connector 1 in the plugged state of the differential plug connection 20 to contact. The first mating contact element 22 ₁ and the second mating contact element 22 ₂ are spaced apart from the outer conductor mating contact element 24 of the differential mating connector 5 in an electrically insulated manner by an insulator element 23. The two mating contact elements 22 ₁ and 22 ₂ are in a third longitudinal section 25 of Counter contact element pair 21 are each bent relative to a fourth axis of rotation 17 ₄ by a fourth angle of rotation φ ₄ at the height of preferably 90 ° and have the same electrical length. The first mating contact element 22 ₁ and the second mating contact element 22 ₂ are each linear in the first longitudinal section 26 of the mating contact element pair 21 at the plug interface and in the second longitudinal section 27 of the mating contact element pair 21 at the cable interface and each have the same electrical length.

This results in a differential electrical plug connection 5, which each has the same electrical length in all longitudinal sections of the contact elements 7 ₁ and 7 ₂ or the mating contact elements 22 ₁ and 22 ₂ and thus advantageously does not produce any phase offset (skewing) in the differential signal.

Although the present invention has been fully described above using preferred exemplary embodiments, it is not limited to this but can be modified in a variety of ways.
