本考案は圧接接続用平型ケーブルの構造に関す

平型ケーブルは別名フラツトケーブルあるいは

Conventionally, as a flat cable and a connector for this flat cable used for this type of purpose, those shown in FIGS. 4 and 5 are known.
即ち、従来の平型ケーブルA′は、等間隔かつ

成されている。 That is, the conventional flat cable A' is formed into a ribbon shape by insulating and covering a plurality of conductors a arranged in parallel at regular intervals with a flexible insulator b such as synthetic resin or rubber. In addition, as shown in Fig. 5, the connector for this flat cable A' has a pressure contact terminal c protruding from one end surface, and a terminal insertion hole d for a mating connector (not shown) on the other end surface. and a housing that accommodates therein a connecting terminal e for connecting to a mating connector connected to the pressure contact terminal c.
B 1 ′, and a pressure contact tool B 2 ′ for connecting the flat cable A′ to the pressure contact terminal c of the housing B 1 ′,
The pressure contact tool B 2 ′ is provided with a hole f into which the pressure contact terminal c is inserted, corresponding to the pressure contact terminal c of the housing B 1 ′, and also corresponds to a plurality of grooves g formed on the surface of the flat cable A′. It is formed into a rectangular parallelepiped with a plurality of protrusions h.
しかして、ハウジングB1′の圧接端子ｃに平型

ーブルA′の凹条ｇに圧接具B2′の凸条ｈを合致さ

ことにより、平型ケーブルA′の導体ａが圧接端
子ｃの対向する圧接刃c1に当接し、圧接接続され
るものである。 Therefore, when connecting the flat cable A' to the insulation displacement terminal c of the housing B 1 ', the concave groove g of the flat cable A' is aligned with the protrusion h of the insulation displacement tool B 2 ', and the insulation displacement terminal c is connected to the insulation displacement terminal c. By inserting the flat cable A' into the hole f of the pressure contact tool B2 ', the conductor a of the flat cable A' comes into contact with the opposing pressure contact blade c1 of the pressure contact terminal c, and a pressure contact connection is established.
しかし、かかる従来の平型ケーブルA′にあつ

B′に引張力が作用し、同様に平型ケーブルA′が
破断する等の欠点がある。 However, in such a conventional flat cable A', since the conductor a is evenly pressed into the pressure contact terminal c by the pressure contact tool B2 ', there is no effect on the tension acting on the conductor a in the axial direction. There is no problem, but if the wiring harness of a car gets caught, flat cable A' will also be bent excessively due to the nature of the wiring harness, and conductor a of flat cable A' connected to connector B' will be bent. Fracture occurs at the side end where the tensile force in the direction is strongest.
Also, when installing a wiring harness on a car, the wiring harness must be pulled and routed in order to pass through the through-hole in the body, but in this case, there is a risk that the connector B' may get caught in the through-hole or corner of the body. There are many connectors at this time.
There are drawbacks such as tensile force acting on B' and flat cable A' breaking as well.
そこで、この欠点を改善するため、実開昭50−

A flat cable as disclosed in Publication No. 111684 has been proposed. In other words, this flat cable
As shown in Fig. 6, A'' is a structure in which flexible reinforcing wire i is arranged on the same plane of a plurality of conductors a covered with insulator b and arranged in parallel. i is a flat cable as shown
The conductor a placed at both ends of A'' is covered with an insulator b, or is placed between the conductors a.

期待できないという問題がある。 However, even if the flat cable A'' in which the reinforcing wire i is placed outside the conductor at both ends is press-connected to the connector B' shown in Fig. 5, the press-connecting force by the press-connecting tool B2 ' is It acts to press conductor a to terminal c, but has almost no effect on reinforcing wire i, so
When a tensile force due to bending similar to that described above is applied to the flat cable A'' that is press-connected to the connector B', the stress mainly acts on the conductor a, which tends to cause fatigue rupture due to deformation or stress concentration. There is a problem in that the reinforcing wire i cannot be expected to have a large protective effect on the flat cable.

Since the flat cable of the present invention has the structure and function described in detail above, even the flat cable, which is made of thin conductors and is extremely easy to break, can be effectively protected by the reinforcing wire material, and as a result, wiring harnesses in automobiles can be effectively protected. This function prevents breakage at the connector pressure welding part of the flat cable, which is particularly likely to occur during the process, and also prevents damage to the flat cable or the pressure welding connector due to work such as attaching and detaching the flat cable to the pressure welding connector during unit maintenance. This has the advantage of significantly reducing physical problems and allowing smooth application of flat cables to automobiles, which is required in response to measures against enlarged wiring harnesses.
