Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method of attaching a vehicle body mounting clamp to a wire harness for fixing and arranging a vehicle wire harness at key points of the vehicle body. be.

``Prior Art'' Conventionally, the above-mentioned vehicle body mounting clamp (hereinafter simply referred to as a clamp) has a shape that has a plate-shaped mounting portion with a protruding locking head with an elastic check piece, or a lock with an elastic check piece. These clamps have a mounting band at the base of the head, and after the wires of the wire harness are bundled and wrapped with tape, they are attached to each other at the desired position on the outer periphery using a mounting jig. The attachment interval and attachment direction are regulated, and the attachment portion is manually wrapped several times with adhesive tape or the like, or the attachment band portion is tightened and attached to the outer periphery of the wire harness.

The locking heads with elastic check pieces of these clamps are fitted into mounting holes at key points in the vehicle body, and the wire harness is arranged and fixed to the vehicle body.

``Problems to be Solved by the Invention'' The clamps installed using the conventional method described above cannot be said to have sufficient attachment force to the wire harness compared to the holding force required to hold the wire harness in place. Furthermore, since the attachment portion may be improperly attached, there is a problem in that the attachment of the clamp becomes loose, comes off from the outer periphery of the wire harness, or the attachment direction is disturbed, impairing the clamp function.

Furthermore, in the conventional method described above, the clamp is manually attached to the outer periphery of the wire harness, which requires a large number of man-hours and is unfavorable in terms of workability.

An object of the present invention is to provide a new clamp mounting method that solves the above-mentioned conventional problems.

"Means for Solving the Problems" The present invention, which achieves the above-mentioned objects, has been achieved by focusing on the simultaneous installation and installation of clamps when wiring harnesses are bundled, and the gist thereof is as follows: Wire harness wiring diagram shows a vehicle body mounting clamp that has a locking head with an elastic non-return piece on one side of a plate-shaped base and a locking part for hooking and locking electric wires in a zigzag pattern on the other side. Temporarily lock the locking head to a clamp jig provided on the board, and then connect the locking portion while wiring the wire group to the wiring jig on the wiring diagram board and the clamp jig. This method involves hooking and locking several electric wires in a zigzag pattern to form an electric wire bundle, and then binding the electric wire bundle and attaching and fixing the clamp to the electric wire bundle.

"Operation" According to the above-described mounting method of the present invention, the clamp, which has the base portion hooked and locked with the electric wires of the wire harness in a zigzag pattern, is mounted and fixed at key points on the outer periphery of the wire harness, so that the mounting force of the clamp is reduced. This is sufficient and the clamping function can be stabilized well. Further, since the work of wiring the wires and the work of attaching the clamps are synchronized, the work efficiency is significantly improved.

"Example" Hereinafter, a detailed explanation will be given with reference to examples.

First, in FIGS. 1 to 3 showing one embodiment thereof, FIG. 1 shows the procedure and means of the clamp mounting method according to the present invention, and FIG. 3 shows the clamp used therein.
A locking head 5 having elastic check pieces 7A and 7B is provided on one side (lower side in the drawing) of a plate-shaped base 6,
There are three hooks 8A, 8B, 8C on the other side of the base 6.
are formed in a staggered manner. And the hook part 8A~
8C is designed to lock two or three wires of the wire harness in a zigzag pattern so that they do not come off easily. That is, the hook parts 8A to 8C are attached to the base 6.
The wires are arranged in a staggered manner along both left and right edges of the wires, and are formed in a hook shape into which electric wires are inserted and hooked from the outside of the edges. Note that the locking head 5 having the elastic check pieces 7A, 7B is the same as the conventional one. Further, the base portion 6 has a shallow concave shape in order to fit along the outer periphery of the wire harness.

As shown in Fig. 1, the above-mentioned clamp 2 is mounted on a known wiring drawing board (a board in which a large number of wiring jigs are arranged along the wiring shape of the wire harness) used for forming the wiring of the wire harness. A clamp jig 9 is erected in combination with the wiring jig at the required position, and the locking head 5 is temporarily fixed to the tip of the clamp jig 9, and the locking parts 8A to
Install with 8C facing the wire entry direction. In addition, 1 in the figure
0 is a wiring guard provided on the clamp jig 9.

Next, the wiring jig on the wiring board (not shown)
In addition, the wire harness wires 1 are sequentially inserted into the clamp jig 9, and the first two to three wires are latched to the hooks 8A to 8C of the clamp 2 in a zigzag pattern as shown in the figure, and the wires are Group 1 is stacked one after another to form a wire bundle.

Thereafter, tape wrapping 11 or the like is applied to a predetermined position on the outer periphery of the bundle of wires to bind the wire bundle, and a clamp 2 is fixed to the outer periphery of the wire bundle as shown in FIG.

Then, the wire bundle with the clamp 2 inserted therein is further taped on its outer periphery if necessary, and is removed from the clamp jig and wiring jig that temporarily fix the locking head 5, and the wire harness 3 is formed. be done.

According to the above-described clamp installation method of the present invention, the clamp 2 is attached and fixed to the outer circumference of the wire harness by hooking several bundled electric wires in a zigzag shape to the base 6 of the clamp 2, so that the installation of the clamp 2 is stable. There is no fear that the attachment of the clamp will loosen or come off unlike in the past, and the clamp function can be stabilized well.

Furthermore, since the wiring of the wire group 1 and the attachment of the clamps can be performed in synchronization, the conventional complicated work of manually attaching the clamps to the outer periphery of the wire harness is eliminated, and the number of man-hours for forming the wire harness is significantly reduced.

Next, FIG. 4 shows a clamp 2' used in another embodiment of the present invention, and one side of the plate-shaped base 6 of the clamp 2' is provided with a lock having elastic check pieces 7A and 7B. A head 5 is provided, and nail-shaped hooking portions 8A to 8D arranged in a row are provided on the other side. Then, as shown in FIG. 5, several electric wires 1
are hung in a zigzag pattern.
This embodiment has the advantage that the lateral fixing force of the clamp is further increased. Incidentally, the clamp 2' is attached and fixed to the outer periphery of the wire harness 3 by the same procedure and means as in the previous embodiment.

"Effects of the Invention" As described above, according to the clamp attachment method of the present invention, the clamp fixation to the wire harness is improved, the clamp function is well stabilized, and the wire harness molding workability is improved. effective.
