Abstract

PURPOSE:To adapt even to the case when the interval of the neighboring conductors is extremely narrow each other by cutting a covered circuit body partially in the thickness direction to expose the conductor. CONSTITUTION:A part of the insulating coverage 1 and the conductor 6 at the terminal 4 of a flat circuit body 3 is cut in the longitudinal direction in a plane form to expose the conductor 6a in a plane form. And, to a U-shape elastic holder member 7, the terminal 4 of the flat circuit body 3 is bent along the outer wall surface 8 of the holder member 7 and fixed, and the exposed conductor 6a of the flat circuit body 3 is positioned at the surface of the elastic holder member 7, to complete a terminal connector 9. Since the connection is formed by exposing the conductor 6a in such a way, the structure is simple, and the connection can be formed simply even though the interval of the neighboring conductors is narrow each other.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connection structure for connecting a covered circuit body such as a covered single wire or a flat cable to a mating circuit.

[Conventional technology]

FIGS. 6(a) to 6(C) show the structure of a conventional connection part of a covered circuit body.

FIG. 6(a) shows a flat cable 24 in which a plurality of round conductors 22 are bundled in a plane with an insulating coating 23, and as shown in FIG. 6(b), the flat cable 24
The round conductor 22 of No. 4 is connected to a circuit (not shown) connected to the pressure contact terminal 26 using a pressure contact connector 25 . That is, the pressure contact terminal connector 25 is connected to the housing body 2.
7, a plurality of insulation displacement terminals 26 erected on the housing body 27, and an upper cover 28, and as shown in FIG. 6(C), the flat cable 24 is placed on the insulation displacement terminals 26, By fitting the upper cover 28 from above, as shown in FIGS.
The round conductor 22 is inserted into the slot 30 and connected.

However, in the above-mentioned conventional connection structure, since the pressure contact connector 25 is required, the cost is high and, for example, in a circuit body in which enameled wires are bundled together in a plane, adjacent conductors are connected to each other. There is a problem in that it cannot be applied to cases where the interval between the two is extremely narrow.

[Problem to be solved by the invention]

In view of the above-mentioned points, it is an object of the present invention to provide a connection structure for a covered circuit body that is inexpensive in cost and applicable even when the distance between adjacent conductors is extremely narrow.

[Means to solve the problem]

In order to achieve the above object, the present invention is based on a connection structure in which a part of a covered circuit body is partially removed in the thickness direction to expose a conductor part.

It is also possible to fix the conductor part to a holding part hole and fit the holding member into a mating connector or the like.

[For production]

The structure is simple because the conductor portion is exposed and the connection portion is formed by partially removing the covered circuit body in the thickness direction. Here, even if the distance between adjacent conductors is narrow, it is easy to expose the conductor portions, so the connection portion can be easily formed.

By fixing the conductor portion to the holding member, it can be easily and reliably fitted into a mating connector etc.
A reliable electrical connection is made.

〔Example〕

FIGS. 1 to 3 show, in order of process, one embodiment of the connection part structure of a covered circuit body according to the present invention.

FIG. 1(a) shows a flat circuit body 3 formed by converging a plurality of enameled wires 2 covered with an insulating coating 1 in a planar manner. Note that as a method of bundling, there are a method of heating self-fusing wires to adhere them to each other, a method of using an adhesive, a laminating method of covering with an insulating film, and the like.

FIG. 1(b) shows the state in which the surfaces of the terminal portions 4 of the flan 1 to the circuit body 3 are cut in the longitudinal direction by the cutter 5, and FIG. 1(C) shows the state after cutting. be. That is, the insulation coating 1 of the terminal part 4 of the flat circuit body 3 and a part of the conductor 6 are cut planarly in the longitudinal direction to form the conductor part 6.
Expose a in a plane.

Then, as shown in FIG. 1(d), the flat circuit body 3 is bent with the terminal portion 4 (insulating coating portion 1) along the outer wall surface 8 of the U-shaped elastic holding member 7. and fix it,
The exposed conductor portion 6a of the flat circuit body 3 is positioned on the surface of the elastic holding member 7, and the terminal connector 9 is completed. Here, the terminal portion 4 of the flat circuit body 3 is fixed by a method such as applying a thermoplastic adhesive and adhering it to an elastic holding member by applying heat and pressure.

Further, as shown in FIG. 2(a), the elastic holding member 7 has a substantially U-shaped holding piece IO made of synthetic resin to impart spring properties to the holding piece 10. An insertion frame 11 for the flat circuit body 3 is integrally formed on the outside of one end of the holding piece 10. Further, as shown in FIG. 2(b), the elastic holding member 7a may be formed by integrally forming a solid holding body 12 and an insertion frame 13 made of base rubber.

FIG. 3 shows a state in which the terminal connector 9 is connected to the mating connector 14.

That is, the mating female connector 14 having the male tab terminal 15
On the other hand, when the terminal connector 9 is inserted, the conductor portion 6a of the terminal connector 9 comes into contact with the male tab terminal 15, and the elastic holding member 7 holds the housing inner wall surface 16 of the mating female connector 14 in the direction of arrow A. Because of the bias, the conductor portion 6a can strongly abut against the male tab terminal 15 to obtain reliable electrical contact.

The above embodiment uses enameled wire 2, but
The present invention provides a plurality of single fiber wires 1 as shown in FIG. 4(a).
The present invention can also be applied to a flat circuit body 19 in which the circuit elements 7 are converged in a plane with an insulating coating 18. Figure 4(b)
As in FIG. 1(b), the terminal portion 20 of the flat circuit body 19 is cut using the cutter 5 to form the conductor portion 17a.
is exposed.

Furthermore, the connection point is not limited to the terminal section 20, but can also be connected at the intermediate section of the flat circuit body 19, as shown in FIG. That is, the insulating coating 18 at the intermediate portion of the flat circuit body 19 is removed by the cutter 5 to expose the conductor portion 17b, and an elastic holding member formed in a convex shape made of synthetic resin or rubber is attached to the back side of the conductor portion 17b. 31 and the conductor portion 17b is made to protrude to form the connection portion 21. Then, the connecting portion 21 is fitted and connected to a mating connector (not shown) or the like.

〔Effect of the invention〕

As described above, according to the present invention, the conductor part is exposed by partially removing the covered circuit body in the thickness direction to form the connection part, so the structure is simple and the connection part is simple. Cost can be reduced. Furthermore, since the present invention can be applied even when the distance between the conductors of the circuit body is extremely narrow, the connecting portion can be made more compact. In addition, the connection part (
By fixing the conductor portion (conductor portion) to the holding member, a simple and reliable electrical connection is possible.
