Detailed Description

In order to clearly understand the technical features, objects and effects of the present invention, the embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 19, the present application provides a connection structure of a flat circuit body and a conductive mechanism, comprising a flat circuit body 1 and a conductive mechanism 2, the flat circuit body 1 comprising at least one conductor 11 and an insulator 12 wrapping the conductor 11; the conductive mechanism 2 at least has a first connection portion 21 and a second connection portion 22, the first connection portion 21 and the second connection portion 22 are electrically connected to the corresponding conductor 11, respectively, or the first connection portion 21 is electrically connected to the corresponding conductor 11, and the second connection portion 22 is electrically connected to the external connection wire 3.

It is understood that the flat circuit body 1 may be an FPC or an FFC, and is formed of an insulator 12 formed of two insulating layers and one or more flat conductors 11 press-fitted between the two insulating layers, and has a flat belt shape as a whole, each conductor 11 is in a belt shape extending straight by a predetermined width, and the plurality of conductors 11 are arranged in parallel at intervals.

In the connection structure, the first connection part 21 and the second connection part 22 of the conductive mechanism 2 can be respectively connected with different conductors 11, so that the current convergence between loops where the different conductors 11 are located can be realized; the first connection portion 21 of the conductive mechanism 2 may also be used to connect the conductor 11, and the second connection portion 22 is connected to the conventional external wire 3, so as to convert the interface of the loop where the conductor 11 is located into the conventional wire form, and further facilitate the converging connection between the loop and other loops. The whole structure is relatively simple, the operability is high, the practicability is strong, the cost is low, and the bottleneck that the FFC and the FPC are applied to the field of vehicle-mounted electrical connection application and the traditional wiring harness is broken through.

In a specific implementation manner, the following two cases can be classified according to whether the second connection portion 22 of the conductive mechanism 2 is connected to the conductor 11 or the external lead 3:

the first type: the second connecting portion 22 of the conductive member 2 is connected to the conductor 11

In order to facilitate the installation connection, the first connection portion 21 and the second connection portion 22 are electrically connected to the corresponding conductor 11 through the insulator 12 (i.e., by piercing and crimping); alternatively, after stripping at least part of the insulator 12, both the first connection portion 21 and the second connection portion 22 are electrically connected to the corresponding conductors 11.

Under the circumstances, when the puncture crimping mode is adopted for connection, the following situations can be divided according to the actual confluence requirement:

the first method comprises the following steps: the first connecting portion 21 and the second connecting portion 22 can pierce the insulator 12 in the same flat circuit body 1 and are respectively press-contacted with different conductors 11 in the flat circuit body 1.

In this case, the conductive mechanism 2 is used to connect different conductors 11 in the same flat circuit body 1, and the current convergence between different circuits in the same flat circuit body 1 can be realized.

In this way, the length direction of the first connecting portion 21 should be parallel to the length direction of the second connecting portion 22, and the tooth direction of the pressure contact teeth 26 in the first connecting portion 21 should be the same as the tooth direction of the pressure contact teeth 26 in the second connecting portion 22, so as to facilitate the processing.

And the second method comprises the following steps: as shown in fig. 1 to 5 and 6 to 9, the first connection portion 21 and the second connection portion 22 can pierce the insulators 12 in the two flat circuit bodies 1, respectively, and press-contact the conductors 11 in the two flat circuit bodies 1, respectively.

In this case, it is mainly applied that the number of the flat circuit bodies 1 is two and the flat circuit bodies are stacked, and the number of the conductive mechanisms 2 is one and the flat circuit bodies 1 are located between the two flat circuit bodies. By connecting the respective conductors 11 in the two flat circuit bodies 1 with the conductive mechanism 2, the confluence between the respective circuits in the two flat circuit bodies 1 can be achieved.

In this manner, the longitudinal direction of the first connecting portion 21 may be parallel to the longitudinal direction of the second connecting portion 22, as shown in fig. 1 and 5, when the longitudinal directions of the conductors 11 in the two flat circuit bodies 1 are parallel to each other; alternatively, the longitudinal direction of the first connecting portion 21 and the longitudinal direction of the second connecting portion 22 may have an angle therebetween, and the angle may be more perpendicular to each other, as shown in fig. 3, where the longitudinal directions of the conductors 11 in the two flat circuit bodies 1 are perpendicular to each other. The tooth direction of the pressure contact teeth 26 in the first connecting portion 21 and the tooth direction of the pressure contact teeth 26 in the second connecting portion 22 may be the same or opposite; it is more preferable in this embodiment that the teeth of the two are opposite (for example, the teeth of the crimping teeth 26 in the first connecting portion 21 face upward and the teeth of the crimping teeth 26 in the second connecting portion 22 face downward as shown in fig. 2 and 4), which further facilitates assembly.

And the third is that: as shown in fig. 10 and 11, the conductive mechanism 2 further has at least one third connecting portion 23, and each third connecting portion 23 is capable of piercing the insulator 12 in the corresponding flat circuit body 1 and press-contacting the corresponding conductor 11.

In this case, it is mainly applied to the case where the number of the flat circuit bodies 1 is equal to or greater than three and the flat circuit bodies are divided into two layers to be stacked, the number of the conductive mechanisms 2 is one and located between the two layers, and the total number of the first connecting portions 21, the second connecting portions 22, and the respective third connecting portions 23 in the conductive mechanisms 2 is the same as the number of the flat circuit bodies 1. The first connecting portion 21, the second connecting portion 22, and each of the third connecting portions 23 in the conductive mechanism 2 are connected to the corresponding conductors 11 in the different flat circuit bodies 1, respectively, and the confluence between the corresponding circuits in the plurality of flat circuit bodies 1 can be achieved.

In this manner, the length direction of the third connection portion 23 may be parallel to the length direction of the first connection portion 21 or the second connection portion 22, or an included angle may be formed between the length direction of the third connection portion 23 and the length direction of the first connection portion 21 or the second connection portion 22, and when the included angle is formed, the included angle is perpendicular to the both directions. According to the arrangement requirement, the number and the arrangement direction of the flat circuit bodies 1 respectively positioned in the two layers can be the same or different, the arrangement direction of the plurality of flat circuit bodies 1 in the same layer can be the same or different, and intervals are required to be arranged among the plurality of flat circuit bodies 1 in the same layer; the number and arrangement direction of the flat circuit bodies 1 in these two layers determine the total number and arrangement direction of the connecting portions in the conductive mechanism 2.

The teeth of the crimp teeth 26 in the connection portions connected to each conductor 11 in the same layer should be in the same direction (e.g., the teeth of the crimp teeth 26 in the second and third connection portions 22 and 23 are facing upward as shown in fig. 11), and the teeth of the crimp teeth 26 in the connection portions connected to each conductor 11 in different layers may be in the same direction or in opposite directions; it is more preferable in this embodiment that the teeth of the two are opposite (for example, according to fig. 11, in which the teeth of the crimping teeth 26 face downward in the first connecting portion 21, as opposed to the teeth of the crimping teeth 26 face downward in the second and third connecting portions 22 and 23), and the assembly is further facilitated.

Further, the above-described first connection portion 21, second connection portion 22, and third connection portion 23 may each include a plurality of branch connection portions 24 arranged at intervals in parallel (specifically, arranged at intervals in the width direction of each connection portion), and each branch connection portion 24 can be crimped with a different conductor 11 in the same flat circuit body 1.

The number of branch connecting parts 24 included in each connecting part may be the same or different as necessary; the length direction of the branch connection portions 24, that is, the length direction of the corresponding connection portion, and each branch connection portion 24 has the above-described bottom plate 25 and both side crimping teeth 26 to achieve piercing crimping. For example, referring to fig. 6 and 8, each of the first connection portion 21 and the second connection portion 22 has three branch connection portions 24. Referring to fig. 10, each of the first, second, and third connection portions 21, 22, and 23 has three branch connection portions 24.

Further, referring to fig. 2 and 11, each of the first connecting portion 21, the second connecting portion 22 and the third connecting portion 23 includes a base plate 25 and a plurality of crimp teeth 26 provided at both side edges of the base plate 25, and each crimp tooth 26 is pierceable by the insulator 12 on both sides of the corresponding conductor 11 and the insulator 12 outside a surface on one side of the conductor 11 and is crimped onto the surface of the conductor 11 by bending.

Generally, the number of the crimp teeth 26 on both sides of the bottom plate 25 may be the same or different, and the crimp teeth 26 on both sides of the bottom plate 25 are preferably arranged in a staggered manner along the length of the bottom plate 25. Corresponding through holes are formed in the positions, needing to be pierced, of the insulator 12, and two insulating layers outside the surfaces of the two sides of the conductor 11 are respectively marked as a first insulating layer 121 and a second insulating layer 122; when the base plate 25 is placed against the first insulating layer 121, the crimp teeth 26 on both sides of the base plate 25 can be pierced by the corresponding through-holes in the insulating body 12 on both sides of the corresponding conductor 11, and then the crimp teeth 26 are bent to be pierced by the corresponding through-holes in the second insulating layer 122 and to be in surface contact with the inner conductor 11; the piercing and crimping are carried out in a similar manner when the base plate 25 is arranged against the second insulating layer 122.

The second type: the second connecting part 22 of the conducting mechanism 2 is connected with the external lead 3

In such cases, the following cases can be classified according to actual confluence needs:

the first method comprises the following steps: as shown in fig. 14 and 15, the first connecting portion 21 can pierce the insulator 12 in the flat circuit body 1 and press-contact the corresponding conductor 11, and the second connecting portion 22 can be connected to the external lead 3.

In this case, mainly for a single flat circuit body 1, a conductive mechanism 2 is used to connect the flat circuit body 1 and a conventional external wire 3, the conductive mechanism 2 plays a role of switching, and an interface of the conductor 11 can be converted into a conventional wire form, so that the flat circuit body 1 can be conveniently connected and converged with other conventional loops by using a conventional wiring harness process, and the FPC or FFC can be more conveniently used.

And the second method comprises the following steps: as shown in fig. 19, the flat circuit bodies 1 and the conductive mechanisms 2 are equal in number and are multiple in number, the first connecting portion 21 of each conductive mechanism 2 can pierce through the insulator 12 in the corresponding flat circuit body 1 and press-contact with the corresponding conductor 11, the second connecting portion 22 thereof can be connected to an external lead 3, and the external leads 3 are connected in a confluent manner.

This kind of condition specially adapted a plurality of flat circuit body 1 are far away inconvenient to utilize the above-mentioned first kind condition to realize the situation of converging, are connected each flat circuit body 1 through electrically conductive mechanism 2 and traditional external conductor 3, adopt traditional pencil technology with each external conductor 3 again to link together, alright realize in a plurality of flat circuit body 1 between the corresponding conductor 11, simple and convenient. And the confluence point of each external lead 3 can be connected with other loops to be connected through the corresponding external lead 3 according to needs.

In the second case, the length direction of the first connecting portion 21 may be parallel to the length direction of the second connecting portion 22, or the length direction of the first connecting portion 21 and the length direction of the second connecting portion 22 may have an included angle therebetween, and the included angle is more vertical than the included angle. The tooth direction of the pressure contact teeth 26 in the first connecting portion 21 and the tooth direction of the pressure contact teeth 26 in the second connecting portion 22 may be the same or opposite; in this embodiment, it is more preferable that the two teeth are opposite in direction, which is more convenient for assembly.

In addition, the structure of the first connecting portion 21 for achieving piercing and pressing is the same as that of each connecting portion in the first case, and is not described herein again; the second connecting portion 22 can be connected to the conventional external lead 3 by conventional crimping or welding.

In the first and second cases, the first connection portion 21 and the second connection portion 22 or the first connection portion 21, the second connection portion 22 and each third connection portion 23 are integrally connected by the intermediate connection portion 27, and the shape of the intermediate connection portion 27 is adaptively adjusted according to actual conditions. Further, as shown in fig. 12, 13, 14, 15 and 19, an insulating tape 4 is adhered to at least one side surface of the flat circuit body at a position corresponding to the conductive mechanism 2.

Since the conductor 11 is exposed at the location of the piercing-crimping, it is necessary to adhere the insulating tape 4 to the side of the flat circuit body 1 where the crimping teeth 26 bend to pierce the insulating layer, for better electrical protection and improved mechanical strength of the structure.

In summary, the connection structure in this embodiment utilizes the characteristics of the FPC and the FFC, and can not only puncture the crimping target conductor through the corresponding connection portion of the conductive mechanism 2, and can perform the confluence between the parallel stacked flat circuit bodies 1, between the vertically stacked flat circuit bodies 1, but also between arbitrary loops of the flat circuit bodies 1 themselves, and after the confluence, perform the insulation treatment with the insulating tape 4, and the design is simple, the operability is high, the practicability is strong, so that the FFC/FPC breaks through the bottleneck in the application field of the vehicle-mounted electrical connection. The corresponding connecting part of the conductive mechanism 2 can be used for piercing and pressing a target conductor and connecting the target conductor with the traditional external lead 3, the related potential current of the conductor 11 to be converged is transferred to the traditional external lead 3, the current convergence of a loop in an FFC/FPC (flexible flat cable/flexible printed circuit) wire harness is carried out by a traditional process method, or the loop in the FFC/FPC wire harness is connected with the traditional wire harness in a loop manner, the bottleneck of the application of the FPC and the FFC on the traditional wire harness is broken through, the application penetration of the FFC and the FPC on a vehicle-mounted electrical connection system is improved, and the weight cost and the space cost of the whole vehicle electrical system are saved.

The above are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention.
