Description

[Detailed description of the invention] This invention relates to a connector with a fixing band.

As is well known, detachable connectors are widely used to connect electrical cables used in automobile electrical equipment, and are used to facilitate electrical connections or to inspect or repair parts of a circuit. It is known to be extremely beneficial.

An example of such a connector is a connector consisting of a male housing in which one group of wire terminals is fixedly held, and a female housing that is removably fitted to the male housing and is correspondingly connected to the other group of wire terminals. It has been known.

In most cases, a connector itself is not fixed to an electric cable and is used in a state in which it protrudes in the air and floats in the air.

This provides the advantage that the connector can be attached and detached very easily.

However, there are cases where it is desired to fix the connector itself to an electrical cable or surrounding structure.

For example, connectors used in electrical equipment in automobiles, which are subject to severe vibrations, can become loose due to the vibrations, resulting in poor electrical contact or colliding with other structural parts, producing noise.

For such devices, it is rather preferable that the connector be fixed in a manner that prevents vibrations as much as possible.

Figures 1 and 2 show an example of connecting wiring inside a car using a conventional connector, with a branch wire 2 branching from wire harness 1 and connecting it to equipment inside the car. The connected lead wire 3 is connected with the connector 4.

This connector 4 consists of a female housing 5 connected to the branch wire 2 and a male housing 6 connected to the node wire 3.

In order to fix such a connector 4, as shown in FIG. was tied to wire group 1.

However, since the connector 4 is made of synthetic resin or the like, simply attaching it from the outside with the string-like body 7 and fixing it requires a large number of parts, which is inconvenient to handle. There were also problems such as difficulty in doing so.

This idea was made in consideration of the above circumstances, and its purpose is to easily fix the connector to a wire cable, etc. by attaching a fixing band to one housing of the connector in advance. The purpose of the present invention is to provide a connector with a band.

This invention will be explained below based on an embodiment shown in FIGS. 4 to 7.

In these figures, the same parts as in FIGS. 1 to 3 are given the same numbers to simplify the explanation.

The connector of this invention is comprised of male and female housings 5 and 6 that are removably fitted into each other, and a fixing band 8 that is removably fixed to the male housing 6.

The male and female housings 5 and 6 may be of known type, and in one embodiment, the upper wall 9a of the housing body 9 of the male housing 6
In this case, a locking arm 10 for connecting to the female housing 5 is integrally provided.

This locking arm 10 has a rising portion 10a formed at the rear end (right end in FIG. 4) of the upper wall 9a.
and an arm portion 10b that bends from this rising portion 10a along the upper wall 9a and extends toward the tip side of the upper wall 9a, and there is a gap 11 between this arm portion 10b and the upper wall 9a. is formed.

The fixing band 8 is fixed by being inserted into the gap 11 on the male housing 6, and includes a plate-shaped bottom plate portion 12 inserted into the gap 11, and a plate-shaped bottom plate portion 12 inserted into the gap 11.
20 Clamping walls 13, 13 rising from both side edges and sandwiching both sides of the locking arm 10, and these clamping walls 13
An arm 14 14 protrudes from one end (the right end in FIG. 5) along the clamping wall and clamps the rising portion 10 a of the locking arm 10 , and further includes an arm 14 .
It has a pair of protrusions 14a, 14a that protrude inwardly from the tip of the locking arm 10 and engage with the rear end surface 10C of the rising portion 10a of the locking arm 10.

Furthermore, one side of the holding wall 13 has a plurality of recesses 15 on one side.
A band 15 having a shape a formed therein is integrally provided, and the other clamping wall 13 is provided with a band fixing portion 16 that locks the recess 15 a of the band 15 .

The distance between the end surface of the bottom plate portion 12 of the fixing band 8 and the protrusion 14a shown in FIG. It is designed to grow larger.

In addition, a supplementary explanation about the band fixing part 16 is as follows.
The band fixing part 16 has an insertion hole 1 through which the band 15 is inserted.
6a, a spring piece 16b extending downward (to the left in FIG. 6) along this insertion hole 16a, and this spring piece 16a.
The protrusion 16C projects from the center of the insertion hole 16a into the insertion hole 16a and engages with the recess 15a of the bundt river 5. The protrusion 16C has an inclined surface 16 on its upper side (right side in FIG. 6). d is formed, and a locking surface 16e that is perpendicular to the penetration direction of the insertion hole 16a is formed on the lower side.

In the connector configured as described above, the fixing band 8 is fixed to the male housing 6 in the following manner.

4 and 5, the bottom plate portion 12 of the fixing band 8 is inserted into the gap 1 between the upper wall 9a of the housing body 9 of the male housing 6 and the locking arm 10.
1, as shown in FIG.
The rising part 10a of the fixing band 8 is inserted into the fixing band 8.
is fixed to the male housing 6.

Next, when fixing this connector to the wire group 1, turn the tip of the band 15 around the wire group 1, and tighten the band fixing part 1.
6 through the insertion hole 16a.

Then, the protrusion 16C provided on the spring piece 16b fits into the recess 15a of the band 15, and the band 15 is fixed to the band fixing part 16.

If the band 15 is further inserted until the wire group 1 is tightly tightened, the female and male housings 5 and 6 that are fitted together are firmly fixed to the wire group 1.

When removing the connector from the wire group 1, move the lower end of the spring piece 16b of the band fixing part 16 in the direction shown by the arrow in FIGS.
A and the protrusion 16C may be disengaged and the band 15 may be pulled out from the insertion hole 16a.

As explained above, in the connector of this invention,
By inserting the fixing band for fixing the connector into the gap between the housing body of one housing and the locking arm attached to this housing, the fixing band can be fixed to the housing. The fixing band can be easily attached to the connector without requiring any new processing, and when necessary, the band can be easily fixed to the band fixing part by rotating it around a fixed object such as a group of surrounding electric wires. The connector can be fixed in place.

Furthermore, since the fixing band is fixed to the housing, there is an effect that the fixed position will not shift due to vibration.
