2. Description of the Related Art Conventionally, a plurality of electric wires are wired in a vehicle such as an automobile, and a plurality of electric wires are attached to a bracket or a stud bolt welded to a steel plate of a vehicle body so as not to be entangled with each other. Is attached, and is bundled and held by the belt of the electric wire holder. However, the wiring may move around the stud bolts due to vibrations caused by running. It is dangerous if there is a device emitting high heat near the wiring. For this reason, conventionally, two bolts have been used or a route has been bypassed to avoid interference with other parts. Further, there has been proposed an electric wire holder that holds the wiring so that not only the position of the wiring but also the direction of the wiring does not change due to vibration or the like. For example, there is one disclosed in Japanese Utility Model Laid-Open No. 2-87189.

[0003]

However, the actual Kaihei 2-8
The conventional wire holder mounting structure disclosed in Japanese Patent No. 7189 has an advantage that the supporting direction of the wiring is limited, but the projection and the locking groove provided on the clip side are aligned on the outer circumference of the stud bolt. If this is not done, the clip cannot be fitted, and there is a problem of directionality because the wiring route does not go in the set direction.Furthermore, the locking projection protruding from the stud bolt causes the bolt of the conventional welding gun to be used. There was a problem that the chuck could not regulate the direction. The present invention solves the problems of the above-described conventional wire holder mounting structure, and regardless of the mounting direction of the stud bolt, the wire holding device fitted to the stud bolt allows the wiring direction to be arbitrarily set. Moreover, it is an object of the present invention to provide an electric wire holder mounting structure that can be easily regulated.

[0004]

In order to achieve the above object, the wire holder mounting structure of the present invention has a stud bolt having a gear-shaped serration formed on the outer peripheral surface of the base portion and an inner bottom peripheral surface of the clip portion. The present invention is characterized in that a detent piece that engages with the serration is formed and is configured by an electric wire holder that is fitted to the stud bolt, and the fitting of the electric wire holder to the stud bolt is in a detent state. .

The wire holder mounting structure of the present invention having the above-mentioned structure is formed on the outer peripheral surface of the base portion of the stud bolt only by fitting the clip portion of the infection holder to the stud bolt in a predetermined direction. The gear-shaped serrations and the clip detents that are provided are locked to each other by blocking the rotation, and the serrations and detents are attached to the outer circumference of the stud bolt and the inner peripheral surface of the clip, respectively. Since a large number are provided in the circumferential direction, the mounting direction of the stud bolt can be arbitrarily set without limitation, and the clip portion can be easily inserted as in the conventional case.

In this case, the serrations provided on the outer peripheral surface of the stud bolt base and the detent pieces formed on the inner bottom peripheral surface of the clip portion of the electric wire holder that engage with each other with respect to the longitudinal direction of the stud bolt. Can be mounted parallel to the longitudinal axis of the stud bolt so that it can slide.

In the electric wire holder mounting structure of the present invention having the above-described structure, the gear-shaped serrations engraved on the outer peripheral surface of the base of the stud bolt and the anti-rotation piece of the clip part mutually extend the length of the stud bolt and the clip part. Since it is provided along the direction, the clip part can be easily inserted as in the conventional case, but the serration and the detent piece are locked together,
The rotation of the stud bolt in the circumferential direction can be completely prevented.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a mounting structure for an electric wire holder according to the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a stud bolt. A screw-shaped or ring-shaped locking projection 11 is engraved on the outer peripheral surface of the stud bolt 1 as in the conventional case, and a gear-shaped serration 12 is formed on the outer peripheral surface of the base portion. To do. The gear-shaped serration 12 is provided parallel to the longitudinal axis of the stud bolt so as to be slidable in the longitudinal direction of the stud bolt.

Reference numeral 2 is an electric wire holder made of synthetic resin, which is fitted to the stud bolt. The electric wire holder 2 has a clip portion 21 fitted to the stud bolt, and a belt-shaped electric wire holding piece 2 for holding an electric wire connected to the clip portion 21.
2 and a loop shape that surrounds the outer circumference of the clip part,
The belt-shaped electric wire holding piece 22 is inserted and the locking piece 23 can be locked.

The clip portion 21 of the electric wire holder 2 has a tubular shape which can be fitted into a stud bolt, and the inner peripheral surface of the clip portion has a gear-shaped serration formed on the outer peripheral surface of the base portion of the stud bolt 1. 12 is formed by protrudingly forming a detent piece 24 that locks with each other.
A locking claw 25 that locks with the ring-shaped locking projection 11 of the stud bolt is provided on the upper inner surface. Similar to the serrations 12, the anti-rotation piece 24 is provided in parallel with the longitudinal axis of the stud bolt, that is, parallel to the longitudinal direction of the clip portion 21, so that when the clip portion 21 of the wire holder 2 is fitted to the stud bolt 1, The detent piece 24 and the serration 12 freely slide in the longitudinal direction of the clip portion 21, but in the circumferential direction of the stud bolt, the detent piece 24 and the serration 12 are locked by locking each other. As a result, the locking claws 25 are fitted to the stud bolts as in the conventional case, and the detent pieces 24 prevent the stud bolts from rotating in the circumferential direction.

The clip portion 21 of the wire holder 2 has a loop-shaped locking piece 2 which surrounds the outer periphery of the clip portion.
Sometimes 3 is connected. Then, a belt-shaped electric wire holding piece 22 for holding an electric wire is connected to this part. The loop-shaped locking piece 23 is formed with a locking hole 23h into which the wire holding piece 22 is inserted and locked. When the belt-shaped wire holding piece 22 is inserted into the locking hole 23h, the wire-shaped wire holding piece 22 is locked to hold the wire bundle and prevent the wires from being unintentionally moved.
A locking claw is formed in the locking hole 23h, and a large number of serrated projections are formed on the wire holding piece 22. The electric wire holding piece 22 is not limited to the one shown in the drawing, and may have a configuration generally adopted conventionally.

Therefore, the stud bolt 1 constructed as described above is welded to the steel plate using a welding gun as in the conventional case.
In this case, the stud bolt has the serration 12 formed on the outer periphery of the base end portion, but since the protrusion of the serration 12 is almost the same as that of the ridge, it can be held by the chuck of the conventional stud gun.

The clip portion 21 of the wire holder 2 is fitted and locked on the stud bolt 1 thus welded to the steel material.
At this time, since the belt-shaped electric wire holding piece 22 is connected to the clip portion 21 of the electric wire holder 2, the protruding direction of the electric wire holding piece 22 is determined. Especially, the wire bundle is the electric wire holder 2.
Make sure that there are no devices that generate high heat near or in the vicinity supported by, and well determine the position or direction so that even if the wiring bundle vibrates, it will not come into contact with or come close to this heat source. Clip part 2 to stud bolt 1
When 1 is inserted to a predetermined position, that is, to the inner part, the serration 12 of the stud bolt and the detent piece 24 are engaged and locked with each other.

In this state, the clip portion 2 of the wire holder 2
In No. 1, rotation of the stud bolt in the circumferential direction is completely blocked. Then, a plurality of wires are bundled, and the outer periphery of the wire is held by a belt-shaped wire holding piece 22 and is inserted from the tip of the wire holding piece 22 into the locking hole 23h of the loop-shaped locking piece 23. It locks. By thus twisting the wire bundle, the position of the wire bundle does not shift or the supporting direction does not change due to vibration or the like, and it is possible to reliably prevent contact with other devices. Further, since the stud bolt can be fitted to other conventional clips or the like, it is possible to reduce the number of bolts in the vehicle structure.
