DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat cable, in particular, a conductor for power is arranged in a plurality of strips, and a branch wire is connected to an intermediate position of the flat power cable in which an insulating layer and a sheath are collectively covered. The present invention relates to a branching sleeve for a flat cable used for manufacturing.

[0002]

2. Description of the Related Art FIG. 5 is a front view of a conventional branch sleeve for a flat cable, and FIG. 6 is a plan view thereof. The conventional branch sleeve for a flat cable is a deep U-shaped sleeve main portion 1a.
And a sleeve body 1 provided with a branch connection terminal plate 1b provided at the U-shaped bent end thereof, and a lid 2 fitted inside the opening of the sleeve main portion 1a and connecting between the two leg pieces.
And

[0003] The connection of the branch cable to the main line is made as follows. First, the core conductor 3a exposed by stripping the sheath of the flat cable from the sleeve main part 1a is exposed.
Is inserted into the opening of the sleeve main part 1a in the longitudinal direction of the row 3 of the conductors 3a, and the sleeve main part 1a is compressed. Is fixed to the row 3 of the conductor 3a.

[0004] Next, a branch cable (not shown) is connected to the terminal plate 1b by rivets, bolts and nuts, etc., and finally required insulation treatment (not shown) is performed to complete the branch connection.

[0005]

In the branch connection portion constructed as described above, the sleeve main portion 1a and the terminal plate 1
b, a heat cycle or the like causes a force in a direction in which the ends of the two legs of the sleeve main portion 1a open to each other, so that the sleeve main portion 1a is insufficiently pressed against the row 3 of the conductors 3a, and branches. There was a possibility that the sleeve could not exhibit the expected performance.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a branch sleeve for a flat cable in which crimping of a conductor of a main portion of a sleeve is not insufficient due to bending, heat cycle, etc. acting on a sleeve body. It is intended to provide.

[0007]

SUMMARY OF THE INVENTION A branch sleeve for a flat cable according to the present invention has a deep U-shape, and a main part of the sleeve which is laterally engaged with a conductor row of a trunk cable, and is formed integrally with the branch. A sleeve main body having a terminal portion for connecting a cable, and a lid which is covered from the outside on both ends of the sleeve main portion at the sleeve main portion opening,
It is characterized by being fixed to the exposed row of conductors by compression.

[0008]

In the branch sleeve for a flat cable according to the present invention, the lid is engaged and fixed to the sleeve main portion in such a manner that both ends of the leg of the sleeve main portion are sandwiched from outside.
Deformation in the direction in which the two leg pieces are opened is suppressed.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of an embodiment of a branch cable for a flat cable according to the present invention, in which the same reference numerals are given to the same parts as in FIGS. 5 and 6, FIG. 2 is a plan view thereof, and FIG. FIG. 4 is an enlarged view of a portion indicated by a circle A in FIG.

In this embodiment, a lid support 4 having a smaller thickness than other portions is formed at an open end of the sleeve main portion 1a so as to protrude therefrom, and an engagement end of the lid 2 with the sleeve main portion 1a is formed. Is formed with a concave portion 5 for sandwiching the lid receiver 4. The lid 2 is made of a material that is stronger than that of the sleeve body 1.

The branch sleeve for a flat cable according to the present invention having the above-described structure is used in substantially the same manner as the conventional branch sleeve shown in FIGS. However, the lid 2 is engaged and fixed to the sleeve main portion 1a so as to sandwich the opening end of the sleeve main portion 1a from both sides.

Since the lid 2 is fixed as described above, the lid 2 can fix the outside of the space between both ends of the leg of the sleeve main portion 1a.

Therefore, the two legs do not move in the opening direction due to bending or other force acting on the sleeve body 1 or a heat cycle, and the sleeve main portion 1a is insufficiently pressed against the row 3 of the conductors 3a. It is not.

The present invention is not limited only to the above embodiment. For example, the present invention can be applied to a branch sleeve having a compression portion for connecting a branch cable instead of the terminal plate. Further, the compressed shape of the lid is not limited to a smooth arc-shaped cross section as shown in the example, but may be a square cross section. Further, the sleeve main part and the fitting part may be dovetailed. Alternatively, a U-shaped concave portion having a conductor presser protruding from the bottom surface of the lid may be provided, a convex portion engaging with the concave portion may be formed on the sleeve main portion, and both may be fitted and compressed.

In the present invention, since the material of the lid that covers the outer end of the sleeve main portion from the outside is made of a material that is stronger than that of the sleeve main body, bending or other force or heat cycle acts on the sleeve, and the sleeve main portion is actuated. Even if the force to open the legs is applied to the ends of both legs, the lid made of a tough material covered from the outside prevents the legs from opening, so the main part of the sleeve and the conductor row Is not insufficient, and the desired performance can be exhibited over a long period of time.

[0017]

As described above, in the branch sleeve for a flat cable according to the present invention, the crimping between the main part of the sleeve and the row of conductors is insufficient even if bending or other force or heat cycle acts on the sleeve. Therefore, the desired performance can be exhibited for a long period of time.
