Description

[Detailed Description of the Invention] The present invention relates to a wire holding device for a fuse block incorporated in, for example, automobiles, ships, communication equipment, etc.

Particularly in automobiles, ships, etc., which have a large number of electrical circuits, fuse blocks in which a large number of fuses are arranged are used.

That is, this type of fuse block is provided with a notch C for leading out a large number of electric wires B connected to a large number of fuses incorporated in a fuse block body A, as shown in FIG. 1, for example. .

When the fuse block main body A is attached to a predetermined location, each electric wire B is pulled out in succession so that it is located in the notch C. However, with this electric wire pulling means, when the block main body A is fixed, the electric wires are pulled out. There is a drawback that the wires can be damaged if they get caught between fixed objects, and in order to prevent the wires from getting caught, caution is sometimes required when assembling the fuse block, which is extremely difficult to assemble. There were drawbacks such as:

The present invention was made to eliminate such drawbacks.The first is that the electric wires drawn out from the fuse block do not get caught between the fuse block and the mounting body when the fuse block is installed. It was made into a structure.

The second feature is a wire holding member that bundles and tightens a large number of wires pulled out from the fuse block so that they do not fall apart.

Thirdly, the wire holding member can be fixed to the fuse block without play.

The present invention will be explained in detail below with reference to FIGS. 2 and 3.

Reference numeral 1 denotes a fuse block body, and a wire outlet 1a for pulling out the electric wire 4 is provided on the side wall of the fuse block body 1.
is provided.

The wire outlet 1a has a square shape in front and is formed to protrude outward from the side wall of the fuse block main body 1, and locking portions 1dx and ldz are provided on both side walls of the wire outlet 1a.

Further, below the locking portions 1d+ and ld2 are inclined surfaces 1C1,
1C2 and serves as a guide surface for a wire holding member, which will be described later.

Reference numeral 3 denotes a front-mounted electric wire holding member that is connected to the electric wire outlet, and the locking arms 3f and 3f2 provided on both side walls of the electric wire holding member 3 are locked with the locking portions 1d1 and 1d2. Locking portions 3d1 and 3d2 are formed.

Also, on the upper side of the rocking arms 3f, 3f2, there is a slope 3c that slides along the slope 1C1 and IC2.
+ and 3C2 are formed.

3g+ and 3g2 are elastic parts provided at the bases of the rocking arms 3f and 3f2 of the electric wire holding member 3, and the lower end surfaces 1g1 and 1g2 on both sides of the electric wire outlet are provided at the center of the elastic parts 3g1 and 3g2. Elastic abutting portions 3ht and 3h2 are provided that are in elastic contact with.

The structure of this embodiment has been described above, and its operation will be described next. After a large number of electric wires 4 are pulled out from the wire outlet 1a of the fuse block body 1, the wire holding member 3 is fitted to the outlet 1a. wear.

That is, when the wire holding member 3 is inserted facing the wire outlet 1a, the pair of locking arms 3f and the slopes 3C1 and 3C2 of 3f2 slide along the slopes 1C1 and IC2 provided in the wire outlet 1a, and Due to the elastic deformation of the locking arm, the wire holding member 3 can be easily inserted into the wire outlet 1a.

When the wire holding member 3 is further inserted, both locking portions 3b
1 and 3b2 are locked with the locking portions 1d and 1d2, and the lower end surfaces 1g1 and 1g2 of the wire outlet 1a are brought into contact with the elastic contact portions 3h and 3h2 of the wire holding member 3.

Therefore, the locking parts 3b1, 3b2 and the locking parts 1d, 1d
2 and an elastic portion 3gt that biases the locking force.
, 3g2 causes the wire holding member 3 to close the wire outlet 1.
It is securely locked to a without any play.

As described above, the present invention provides a fuse block main body 1 made of resin in which a front-shaped groove for inserting electric wires is provided in a part of the fuse block main body, and locking portions 1 d on both sides of the groove. , 1 d2 is provided, and the other locking part that is locked to the locking step is provided oppositely on both sides, and the electric wire holding member 3 is provided with a U-shape in front, and the electric wire holding member 3 is provided with The member has an arcuate elastic portion 3 gt, 3 g that opposes the wire holding member in the direction opposite to the direction in which the wire holding member is fitted into the groove.
2 is integrally provided in a portion of the wire holding member 3 facing the groove, the fuse block electric wire holding device comprising:
Since a large number of electric wires drawn out from the fuse block are bundled at the wire outlet and the wire holding member, when fixing the fuse block main body to a wall surface, for example,
The electric wires drawn out from the fuse block body are not pinched between the block body and the wall surface, so damage to the electric wires is prevented, and the installation work of the fuse block body is extremely easy, which improves the workability. It has an improving effect.

Further, according to the present invention, the wire holding member can be installed with one touch, and once the wire holding member is locked, the locking is held elastically, so there is no play, and therefore, the wire holding member can be installed in a car that vibrates frequently. It is effective for both commercial and marine use.

In the above embodiment, shoulders 1dx, 1 are provided at the wire outlet.
d2, and a locking portion whose shoulder portion is locked to the wire holding member 3 is provided, but the present invention is not limited to this. However, the purpose of this invention is distantly related.
