Description

[Detailed Description of the Invention] (Industrial Application Field) This invention mainly relates to a fastener for a wire harness or the like for fixing the wire harness to the body of a vehicle.

(Prior Art) Conventionally, fasteners of this type as shown in FIGS. 17 and 18 have been used. This fastener includes a holding part 1 having a flat plate shape, and a holding part 1 having a flat plate shape.
The locking leg 2 is secured to the mounting hole H of the vehicle body BP, and the wire harness WH is secured to the holding part 1 with an adhesive tape T. It was worn.

(Problems to be Solved by the Invention) However, in the case of the above-mentioned conventional fasteners, it is said that a complicated work that requires many man-hours is required to fasten the wire harness WH to the holding part 1 using the adhesive tape T. There was a problem. Also,
As shown in FIGS. 19 and 20, the vehicle body is attached to the holding cord 3 which is held in a bundle through an adhesive tape T in parallel with the wire harness WH.
There is also a device in which the locking legs 4 that are locked in the mounting holes H of the BP are arranged at appropriate intervals, but according to this, the twisting of the holding cord 3 that occurs when binding the wire harness WH with the adhesive tape T. According to
There was a problem in that the locking legs 4 and the mounting holes H of the body BP did not correspond, that is, they were misaligned, making it difficult to attach them to each other.

(Means for Solving the Problems) This invention for solving the problems in the conventional technology described above is such that the holding cord held in parallel to the wire harness etc. A plurality of locking parts protruding outward from a part of the outer peripheral surface of the wire harness etc. are provided at predetermined intervals, and on the base of each fixture that can be placed on a fixed side member such as the body of the vehicle. The gist of the configuration is that an engaging portion is formed to be movably engaged with the locking portion within a predetermined range.

(Function) According to the above-described means, the engaging portions of each fixture are respectively engaged with the respective locking portions of the holding cord held in the wire harness etc., and the respective fixtures are disposed on the fixed side member. As a result, the wire harness and the like are secured to the stationary member.

In addition, since the engaging part of each fixture is movably engaged with a plurality of locking parts provided on the holding cord at predetermined intervals within a predetermined range, even if the wire harness etc. is twisted, By arranging each fixture at a predetermined position on the fixed side member, wiring of the holding cord becomes easy.

(Example) An example of this invention will be described below with reference to FIGS. 1 to 6. In FIG. 1, which shows a side view of a fastener such as a wire harness, and FIG. 2, which shows a perspective view of the fastener, this fastener consists of a fixture 10 and a holding cord 20 made of a synthetic resin material.

First, the fixture 10 will be described with reference to FIGS. 3 and 4. The locking leg portion 12 formed on the lower surface of the base 11 is connected to the central shaft 1 protruding from the base 11.
3, and leg pieces 14, 14 which protrude from the lower end of the central shaft 13 in a substantially V shape and have elasticity.
and a protrusion 1 protruding from the upper end of the leg pieces 14, 14.
It consists of 5 and 15. However, both leg pieces 14, 14
By closing against its elasticity, it can be inserted into a mounting hole H formed in the vehicle body (fixed side member) BP.

The base 11 is appropriately set according to the wiring route of the wire harness WH to the vehicle body BP, and there are various shapes other than the shape shown in FIG. 1. On the top surface of this base 11,
An engagement portion 16 having a substantially inverted U-shape is provided, and an engagement hole 17 is formed.

Next, the holding cord 20 will be described according to FIGS. 5 and 6. The linear cord body 21 is provided with locking portions 22 to 22 at appropriate intervals. The locking portion 22 is formed by integrally forming a locking piece 24 in a substantially inverted L shape at the lower part of a bulging portion 23 bulging out on the cord body 21 . A locking pawl 25 that projects upward in a triangular shape is provided at the tip of the locking piece 24 . Therefore, the width A of the locking piece 24 is narrower than the width a of the engagement hole 17 of the engaging portion 16 in the fixture 10, and the locking width of the locking piece 24 is B (the distance between the locking claw 25 and the base of the locking piece 24 facing it) is formed to be larger than the width b of the engaging hole 17, and the wall thickness C of the lower piece of the locking piece 24 is larger than the width b of the locking hole 17. is the aforementioned engagement hole 1
It is formed larger than the height c of 7. Also,
The opening interval D between the locking pawl 25 of the locking piece 24 and the bulging portion 23 is formed narrower than the wall thickness d of the upper piece of the engaging portion 16 of the fixture 10, and The distance E between the lower piece of the piece 24 and the bulging part 23 is larger than the wall thickness d of the upper piece of the engaging part 16 of the fixture 10.

When fastening a wire harness, etc. to the vehicle body BP using the fasteners described above, first connect the mounting hole H of the vehicle body BP and the wire harness WH.
Fixture 1 with a base 11 corresponding to the wiring route of
0 to 10, and insert the locking part 2 of the holding cord 20 into the engaging hole 17 of the engaging part 16 of the fixture 10 to 10.
The second locking piece 24 is inserted against its elasticity. As a result, the opening interval D between the bulging portion 23 of the holding cord 20 and the locking pawl 25 of the locking piece 24 is expanded against the elasticity, and the locking pawl 25 is expanded against the locking pawl 25 of the locking portion 16. At the same time as passing through the engaging hole 17, the locking piece 24 is restored to its original state due to the elasticity, and the locking portion 16 of the locking leg portion 12 and the locking portion 22 of the holding cord 20 are within a predetermined range. movably engaged.

Then, after making the wire harness WH parallel to the holding cord 20 and binding them by wrapping the adhesive tape T, the locking leg portion 12 of the fixture 10
into the mounting hole H of the vehicle body. As a result, the space between the left and right leg pieces 14, 14 narrows against the elasticity, and at the same time as the leg pieces 14, 14 pass through the mounting hole H, both leg pieces 14, 14,
14 is restored to its original state and the protrusions 15, 15 come into contact with the inside of the attachment hole H, so that the body BP fixture 10 is attached in a state where it is prevented from coming off, and the wiring of the wire harness WH is completed.

At this time, even if a positional shift occurs between the locking leg portion 12 and the mounting hole H of the body BP due to twisting of the holding cord 20 that occurs when binding the wire harness WH with the adhesive tape T, the locking leg portion 12 The engaging portion 16 of the holding cord 20 and the locking portion 22 of the holding cord 20
By moving within a predetermined range with
The wiring will be done reliably.

In addition, the following is predicted as other technical means based on the above-mentioned embodiments.
