Description

Closed conductor marker

The present invention relates to a conductor marker for identifying an electrical conductor which can be inserted into the conductor marker.

There are known to be plugged on an electrical conductor conductor markers, and conductor markers which surround the electrical conductor in full and in which this therefore can be inserted only by insertion. Such conductor markers surrounding the electrical conductors can only be used for conductors with a relatively limited conductor diameter, because conductor markers that are too large shift along the electrical conductor or twist around the electrical conductor.

Document EP 1 596 472 A1 discloses a conductor marking sleeve with receiving pockets into which marking labels can be inserted. In one embodiment, the conductor marking sleeve on a receiving pocket, through which the electrical conductor is feasible. In order to use the conductor marking sleeve for electrical conductors of different conductor diameters, on opposite sides of the conductor markers Aufsteckfalten are provided, through which the receiving pocket is divided into two receiving spaces. The smaller the conductor diameter, the further the electrical conductor is placed in one of the two receiving spaces.

As a result, a thin conductor markers is arranged asymmetrically on the electrical conductor and between the receiving spaces pushed back and forth.

The object of the invention is to provide a conductor marker, which is fixedly mounted on the electrical conductor and which is suitable for electrical conductors of different conductor diameters, in particular for electrical conductors with a small conductor diameter.

The object is achieved with a conductor marker having a labeling plate, which is intended for marking or labeling. The conductor marker also has two conductor receptacles, which are provided for the electrical conductor and in which this can be inserted in a joining direction in the conductor marker. The conductor mounts are arranged on the label plate and provided spaced apart in the joining direction. They limit a receiving space for the electrical conductor.

It is preferred that the labeling plate has a labeling surface which can be directly labeled, or to which the labeling means, for example a label or a writable paper, can be applied. In a preferred embodiment form the labeling surface and / or the label plate are flat. However, it is likewise preferred for the inscription plate to be bent in a circumferential direction with respect to the joining direction, in particular round or folded.

The conductor marker is characterized in that it has a diameter compensation, which is arranged in the receiving space and deformable in a direction of deformation transverse to the joining direction. When inserting the electrical conductor, the diameter compensation deforms according to the conductor diameter of the electrical conductor. Particularly preferably, the diameter compensation is designed to be resilient and / or elastic, so that it deforms against a restoring force.

The conductor marker is made of a thermoplastic, preferably of a polyamide, more preferably of a polyamide PA 66. The deformation of the conductor marker or its diameter compensation during insertion of the conductor takes place in the elastic region of the material. Only with very large conductor diameters, the deformation can move in the plastic range of the material.

In a preferred embodiment, the diameter compensation extends in the joining direction. Particularly preferably, he connects the conductor receptacles with each other. Most preferably, the diameter compensation is arranged centrally on the conductor receptacles. However, it is also preferred an embodiment in which it is arranged on the label plate, in particular on a labeling surface opposite the mounting surface, so that it presses the electrical conductor into the conductor receptacles.

The conductor receptacles are preferably designed ring or loop-shaped. Particularly preferably, they each have two ends, which are arranged at a distance from each other on the label plate. Most preferably, the ends of the conductor receptacles are each arranged on the mounting surface of the label plate. However, an embodiment in which the conductor receptacles are arranged on side surfaces of the inscription plate is also preferred.

Since the conductor receptacles are arranged on the inscription plate, the electrical conductor inserted into the conductor marker is in each case completely enclosed by the conductor receptacles and the inscription plate. The conductor marker can therefore not dissolve laterally from the electrical conductor, but is only by moving in or against the joining direction on one of the conductor ends of the electrical conductor out of this again solvable. The insertion of the electrical conductor in the conductor marker is therefore carried out by insertion in a joining direction.

Particularly preferably, the conductor receptacles are resilient. In this embodiment, they deform, in particular during insertion of the electrical conductor or during deformation of the diameter compensation, also against a restoring force.

In a preferred embodiment, the diameter compensation is arc-shaped or wave-shaped, for example as a bow-shaped or wave-shaped web. In this embodiment, it extends into the receiving space. Particularly preferably, starting from the conductor receptacles, it has in each case an insertion ramp, as well as a connecting web connecting the insertion ramps. The insertion ramps each extend at an angle to the label plate and lead the electrical conductor during insertion further into the receiving space and between the contact bar and the label plate. The angle of the insertion ramps to the joining direction is preferably about 30-50 °, more preferably about 40 °. It is preferred that the electrical conductor inserted in the receiving space is jammed between the inscription plate and the diameter compensation, in particular the abutment web.

In order for the electrical conductor, in particular an electrical conductor of small conductor diameter, to be held laterally, it is preferred that a depression is provided in the contact web, so that it at least slightly surrounds the electrical conductor. In addition, it is preferred that one or more centering means are provided on the inscription plate, in particular on the attachment surface, which hold the electrical conductor laterally. The depression in the diameter compensation as well as the centering or the effect also cause that the electrical conductor is arranged approximately centrally below the label plate.

The conductor marker is preferred to a first fictitious mirror surface, which extends in the joining direction and halves the label plate, formed surface-symmetrical. As a result, the electrical conductor is held approximately centrally below the inscription plate. In the case of a curved or kinked inscription plate, by means of which the inscription surface is bent or kinked, a label can also be attached to both sides of the inscription surface which are separated by the first notional mirror surface. A curved or kinked labeling plate, through which the mounting surface is bent or kinked, has the advantage that it may be possible to dispense with additional centering means. In addition, it is preferred that the conductor marker is designed to be plane-symmetrical with respect to a second fictitious mirror surface, which extends transversely to the joining direction and halves the inscription plate. As a result, the electrical conductor is held evenly by both conductor receptacles. In addition, the electrical conductor is thereby insertable from both sides in the conductor marker.

The conductor receptacles are preferably connected to one another by a transverse web which extends in the joining direction and is arranged on the inscription plate. As a result, the connection between the label plate and the ends of the conductor receptacles is more stable.

In order to produce the conductor markers inexpensively, this is preferably made in one piece. It is particularly preferably made of a thermoplastic material.

It is preferred that diameter compensation in each case at least partially taper in the direction of the conductor receptacles and / or the conductor receptacles in each case in the direction of the diameter compensation. As a result, the diameter compensation and / or the conductor mounts deform easier when inserting the electrical conductor, so that it is easier to insert in the conductor marker.

Further preferably, the conductor receptacles at an angle to the joining direction, which is in a range between 30 and 50 °, so that they are spaced less far from each other at their ends, as in the region of the diameter compensation. It has been found that the conductor marker is thereby easier to deform when inserting the electrical conductor according to the conductor diameter and the insertion of the electrical conductor is thereby easier.

The invention with reference to the drawings with reference to embodiments will be explained in more detail, with further advantages of the invention will become apparent. It shows:

The conductor marker 1 of Fig. 1 has a labeling plate 1 1, which is provided for marking or labeling of an electrical conductor 3. In addition, it has two spaced apart in a joining direction 21 of the electrical conductor 3 in the conductor marker 1 conductor receptacles 12. The conductor receptacles 12 are provided for receiving the electrical conductor 3. The electrical conductor 3 can be inserted into the conductor receptacles 12 in the joining direction 21. The conductor receptacles 12 are arranged on the label plate 1 1 and define a receiving space 13 for the electrical conductor. 3

The labeling plate 1 1 has a labeling surface 1 1 1, which is directly labeled, or to which a label (not shown) can be attached. In the embodiment shown here, the labeling plate 1 1 is flat, so that both the labeling surface 1 1 1 and one of the labeling surface 1 1 1 opposite mounting surface 1 12 are flat.

The conductor receptacles 12 are loop-shaped and each have two ends 121, 122, which are spaced from each other on the label plate 1 1, on the mounting surface 1 12, are arranged. They are connected by a transverse web 16, which extends in the joining direction 21 and on the inscription plate 1 1, and here also on the mounting surface 1 12, is connected to each other. As a result, the connection between the label plate 1 1 and the ends 121, 122 of the conductor receptacles 12 is more stable.

So that the conductor marker 1 can be used for electrical conductors 3 of different diameter D (see Fig. 2 (b)), it has a diameter compensation 14. The diameter compensation 14 is arranged in the receiving space 13. It is deformable in a deformation direction 23 transversely to the joining direction 21, so that it is pressed in the deformation direction 23 and out of the receiving space 13 when inserting the electrical conductor 3. In the illustrated embodiment, it connects the conductor receptacles 12 with each other. He is approximately in the middle of the conductor 12 shots arranged so that it is as far as possible from the label plate 1 1 spaced. In order to simplify the deformation, the diameter compensation 14 tapers in the direction of the conductor receptacles 12 and the conductor receptacles 12 in the direction of the diameter compensation 14. The taper of the diameter compensation 14 and the conductor receptacles 12 are by a width b14 of the diameter compensation 14 and a width b12 one of the ladder receptacles 12 pointing double arrow shown.

So that the electrical conductor 3 is arranged approximately centrally in the conductor marker 1, 12 two ramp-shaped projections are provided as centering means 15 on the mounting surface. In addition, a recess 142 is provided in the diameter compensation 14 so that it slightly engages an inserted into the conductor marker 1 electrical conductor 3, in particular an electrical conductor 3 small conductor diameter D. The electrical conductor 3 is thereby not only centered, but also held laterally.

The conductor marker 1 is formed to a first fictitious mirror surface M1, which extends in the joining direction 21 and the inscription plate 1 1 halved, formed surface symmetry. As a result, the electrical conductor 3 is held approximately centrally below the inscription plate 11. In addition, the conductor marker 1 is also formed to a second fictitious mirror surface M2, which extends transversely to the joining direction 21 and the inscription plate 1 1 halved, formed surface symmetry. As a result, the electrical conductor 3 is held approximately equally by both conductor receptacles 12 and can be inserted from both end faces 17 into the conductor marker 1.

In each case one of the conductor receptacles 12 together with the inscription plate 1 1 surrounds the inserted into the conductor marker 1 electrical conductor 3 in full. The electrical conductor 3 is therefore only by moving in or against the joining direction 21 via one end of the electrical conductor 3 also detachable from this. In Fig. 2, a stripped open end of the electrical conductor 3 is visible. The electrical conductor 3 has an electrically conductive core 31, as well as an electrically insulating sheathing 32 surrounding the core 31. The insertion of the stripped end of the electrical conductor 3 in the joining direction 21 into the circumferentially closed conductor marker 1 is shown.

Thus, the insertion of the electrical conductor 3 is easy to carry out, the diameter compensation 14 is web-shaped and extends in the joining direction 21st He has an arc, which is approximately wave-shaped. As a result, it has an insertion ramp 140 starting from the conductor receptacles 12, each extending at an angle 6 to the label plate 1 1. When inserting the electrical conductor 3, this is thereby along one of the insertion ramps

140 led into the receiving space 13 into it. The insertion ramps 140 are connected to each other by a contact bar 141. The electrical conductor 3 is therefore performed when inserting to the contact bar 141 and then between them and the label plate 1 1. Through the recess 142, which is arranged in the contact bar 141, and by the centering means 15, it is guided centrally.

The insertion ramps 140 and the contact bar 141 and the insertion of the electrical conductor 3 into the conductor marker 1 are shown in FIGS. 3 (a) - (e). The comparison of FIGS. 3 (b) - (d) shows the deformation of the conductor marker 1 during insertion of the electrical conductor 3:

In order to show the deformation, in each case a fictitious base 4 is shown below the conductor receptacles 12 in FIGS. 3 (b) - (d). Fig. 3 (b) shows the section through the undeformed conductor marker 1, wherein a distance A of the contact bar

141 to the base 4 is large and a distance L of the conductor receptacles 12 from each other is small. Already when inserting the stripped end of the electrical conductor 3 in the conductor marker 1 and between the contact bar 141 and the label plate 1 1, the conductor marker 1 is deformed, so that the distance A of the contact bar 141 to the base 1 1 decreases and the distance L of the conductor receptacles 12 enlarged from each other. This is shown in Fig. 3 (c). FIG. 3 (d) shows the conductor marker 1 arranged on the electrical conductor 3. Here, the distance A of the contact bar 141 to the base 4 is further reduced and the distance L of the conductor receptacles 12 from each other further increased.

The conductor receptacles 12 have an angle 5 to the joining direction 21, which is here about 40 °, so that they are less far apart at their ends 121, 122, than in the region of the diameter compensation 14. As a result, the conductor receptacles 12 are pre-deformed and the insertion of the electrical conductor 3 is relatively easy only against a low resistance possible.

So that the conductor marker 1 does not unintentionally shift or twist or twist in a circumferential direction 22 about the conductor, the diameter compensation 14 and / or the conductor receptacles 12 are also resilient. When inserted electrical conductor 3 in the conductor marker 1 this is therefore jammed between the contact bar 141 and the label plate 1 1. In addition, the diameter compensation 14 and / or the conductor receptacles 12 are formed elastically, so that the conductor marker 1 from the electrical conductor is again releasable and reusable.

FIG. 4 shows the conductor marker 1 arranged on the electrical conductor 3. The electrical conductor 3 is jammed between the contact bar 141 and the label plate 1 1.

It is possible that the conductor marker 1 is manufactured individually, alternatively, it is also possible that a plurality of conductor markers 1 to a sogn. Conductor marker mat are summarized and a corresponding production tool in a production cycle each generates a conductor marker mat that includes a plurality of conductor markers.
