Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a clamp that is fixed along a wire harness.

Conventionally, clamps that are fixed along this type of wire harness include a stand-alone clamp 1 shown in FIG. 1a and a continuous clamp 5 shown in FIG. was fixed to the base part 2 or 6, which is a so-called completely fixed type.

Therefore, when attaching the stand-alone clamp 1 to a wire harness, as shown in FIG. Both sides of the base part 2 of each clamp 1 and the outer periphery of the wire harness W are wrapped together with the tape 4 while maintaining the specified interval (the interval between the locking holes drilled in the chassis of the vehicle). , it is troublesome to set the dimensions in order to maintain the interval between the locking parts 3 at a specified interval,
However, there were deficiencies in work efficiency, such as difficulty.

In this regard, in the continuous type clamp 5, as shown in FIG. Since it is fixed at 6,
When attached to a wire harness W as shown in FIG. 2b, the aforementioned deficiencies of the stand-alone clamp 1 are eliminated. However, on the other hand, the single type clamp 1 and the continuous type clamp 5 described above have the following common drawbacks.

In other words, when setting the wire harness with clamp (Fig. 1b, Fig. 2b) at the desired position on the car body on the production line of an automobile factory, it passes through many holes drilled in the car body chassis many times. However, with the conventional completely fixed type clamps 1 and 5 as described above, the locking part 3 protrudes outward from the wire harness W, so the locking part 3 is not caught in the hole. Tsute wire harness W
The setting work is not carried out smoothly, and the locking part 3 is often deformed or damaged.

The present invention was developed by focusing on the above points, and its purpose is to make the base part and the locking part, which are the components of the clamp, detachable and attach only the base part to the wire harness with tape. It is fixed by rolling it up, and with the locking part removed from the base part,
To provide a wire harness clamp in which a locking part is inserted into a base part after the wire harness is passed through a number of holes in a production line and set at a desired position.

Next, embodiments of the present invention will be described based on the drawings.

In FIG. 3, reference numeral 7 denotes a clamp according to the present invention, which is composed of a base portion 8 made of synthetic resin and a locking portion 9, and is configured to be detachable.

That is, the base portion 8 includes a rectangular base plate 10 along the wire harness (the wire harness is located on the lower surface of the base plate, although not shown), and the base plate 10.
It consists of engaging portions 12 that removably and slidably lock the locking portion 9 on both longitudinal edges thereof, leaving tape winding portions 11 at both longitudinal ends for attachment to the wire harness.

The engaging portion 12 is connected to the base plate 10, and is set at a height that allows the locking portion 9 to be detached and slidable even when a wire harness is taped and fixed to the tape-wrapped portion 11. a vertical wall 13;
An inverted horizontal wall 14 connected to the vertical wall 13 forms an inverted L-shape, and a groove 15 is formed between the upper surface of the base plate 10 and the lower surface of the inward horizontal wall 14 .

Further, at one end of the groove 15 opposite to each other, a flexible hooking piece 16 that protrudes inward is formed.

Next, the locking portion 9 includes a leg portion 17 that engages with a locking hole (not shown) drilled in the vehicle chassis;
It consists of a rectangular (or square) stepped board 18 to which the base end of the leg part 17 is fixed, and the board 18 is composed of an upper board 19 and a lower board 20 whose width is larger than that of the upper board 19. has been done.

Both longitudinal edges of the lower plate 20 slide within the grooves 15 of the engaging part 12 formed in the base part 8, and both longitudinal edges of the upper plate 19 slide against the inward horizontal walls of the engaging part 12. The base part 8 and the locking part 9 can be attached to and detached from each other by sliding on the end face of the base part 14, and can freely slide.

Furthermore, the hook piece 16 connects the locking part 9 to the base part 8.
When the locking part 9 is inserted into the base part 8, it is displaced outward, and after insertion, it returns to its original position to prevent the locking part 9 from accidentally falling off from the base part 8.

Only the base part 8 of the clamp 7 having the above structure excluding the locking part 9 is fixed by taping together with the wire harness to the tape winding part 11, and the clamp is set at a desired position on the vehicle body. At that time, the locking portion 9 is removed so that the setting operation can be carried out smoothly even when passing through the numerous holes drilled in the vehicle chassis.

Then, in order to lock the wire harness with a base part set at a desired position to the vehicle body at that position, insert the locking part 9 into the engaging part 12 of the base part 8 from either the left or right side, and then The leg portion 17 is inserted and locked by appropriately sliding the locking portion 9 to a position that coincides with the locking hole of the chassis.

As described above, in the present invention, the base part and the locking part, which are the elements constituting the wire harness clamp, are separated and configured to be detachable and slidable, and only the base part excluding the locking part is connected to the wire harness. Since it is fixed to the harness by taping, the work of setting the wire harness to the car body on the production line is extremely smooth.Also, since the locking part is slidable on the engagement part of the base part, it is possible to attach the wire harness to the car body chassis on the production line. The legs of the locking part can be easily aligned with the locking holes, eliminating the drawbacks of conventional completely fixed type clamps, and making it extremely effective as a wire harness clamp.
