Description

[Detailed explanation of the idea] The present invention relates to a wire harness clip.

In machines and equipment that move, such as automobiles, electric wires tend to vibrate and sway as they move, often causing unpleasant abnormalities and causing secondary disasters such as fires due to friction, disconnection, and short circuits in the electric wires. There is a danger of it happening.

Therefore, it is important to securely fix electric wires and wire harnesses to electrical equipment such as vehicle frames and power distribution boxes to prevent vibrations and the like.

However, the conventional method of fixing electric wires requires cumbersome work such as first wrapping multiple layers of adhesive tape, etc., and then fixing it to the frame with wire, and also requires a lot of space, such as in the engine compartment or under the car body. Due to the narrow space, installation work was often difficult.

The present invention was developed with attention to the above-mentioned points, and it is possible to easily concentrate wire harnesses without requiring the above-mentioned troublesome steps.
To provide a wire harness clip that can be fixed and manufactured at low cost.

Next, an example will be described.

In Fig. 1, reference numeral 1 denotes a wire harness clip, in which a pair of clamping plate parts 2, 2' are connected to each other via a base part 2a bent in the same U shape so as to be openable and closable. It is integrally formed from a flexible and elastic member such as plastic.

Chamfers 2b are provided at the open ends of the clamping plate parts 2 and 2', and a locking protrusion 3 having a corner-shaped cross section is provided along the axial direction on one of the clamping plate parts 2, and a locking protrusion 3 is provided on the other clamping plate part 2 along the axial direction. A fitting groove 4 is provided in 2'.

One of the clamping plate parts 2 has a double structure with a thin inner wall 5 and a gap 6, and the inner wall 5 can be freely bent according to the outer circumference of the wire harness due to the gap 6. do.

In the above configuration, as shown in FIG.
When a plurality of electric wires W are inserted through the open end of the clip 1 and locked by the locking protrusion 3 and the fitting groove 4, the electric wires W are easily bundled by the clip 1.

At this time, since the inner wall 5 freely bends in accordance with the outer circumference of the electric wire W and comes into close contact with it, the clip 1 does not slide.

That is, the use of the clip 1 eliminates the conventional troublesome work of wrapping and tying electric wires with adhesive tape, etc.
This makes it easier to confirm even in the event of an accident such as a wire breakage.

Furthermore, the clip 1 can be integrally molded as a long piece, and can be cut and used as appropriate depending on the bundled length and location of the wire harness.

FIG. 3 shows another embodiment of the present invention, in which an uneven portion 5a having a corrugated cross section is formed on a thin inner wall 5 along its axial direction.

In this case, the uneven portion 5a increases the adhesion and frictional force with the electric wire, making it even more difficult for the electric wire to slip, ensuring reliable focusing,
It has a fixing effect.

FIG. 4 shows another embodiment of the present invention, in which a locking pawl 7 is provided protruding from the lower surface of the clamping plate 2, and can be easily engaged using a hole drilled in a member such as the chassis or body of an automobile. It was made so that it could be stopped.

That is, the locking pawl 7 is provided with wing-shaped flexible elastic pieces 9, 9 that are inclined toward the clamping plate 2 at the tip of the support column 8, and has a positioning piece 10 inscribed in the hole edge protruding from the tip. Set and configure.

In this case, as shown in FIG.
9 bends and enters the support column 8 side, returns elastically at the same time as penetration, and its positioning piece 10 abuts against the hole edge 12a,
Locks without shaking.

To remove it, press the flexible elastic pieces 9, 9 against the support column 8 side with your fingers or the like (arrow P) and pull them out.

By providing the lock claw 7 on the clip 1 in this way, it can be easily attached and fixed to the chassis, body, etc. of an automobile.

As explained above, in the present invention, a pair of clamping plate parts are formed of a flexible member such as rubber or plastic so that they can be opened and closed via a U-shaped base part that is curved in the same manner. A locking protrusion extending along the axial direction is provided on one of the facing surfaces, a fitting groove for the locking protrusion is provided on the other side, and at least one of the pair of clamping plate portions is provided with a thin inner wall and a gap portion. It has a heavy structure, has a simple structure, and is easy to manufacture.The wire harness can be bundled and fixed very easily, and the labor and time required in the past can be significantly reduced.
