As shown in FIGS. 2a and 2b, the wire holder 2 according to the present invention includes a wire holder 3 equipped with an arm 4 that can support a bundle of wires 1 over a predetermined length by wrapping tape, and a wire holder 3 with a screw. A connecting part 6 comprising a stud engaging part 9 which is held by the stud 8 by being inserted into the stud 8, and which is connected to the wire holding part 3 to support the part.
Preferably, the clip is a component clip, and both components are molded from synthetic resin. As shown in the figure, both parts are used by being connected to each other, and one of the two parts is provided with an elongated guide groove, and the other part is provided with a T-shaped pin that fits into this guide groove. It is adapted to be slidably connected to the groove. The guide groove and pin may be provided on either of the two parts, but in the following explanation, the guide groove is provided on the connecting part 6.
The following description assumes that the pin is provided on the wire holding component 3.

Details of the connecting component 6 will be explained using FIGS. 3 a to 3 f. The connecting part 6 includes a stud engaging part 9
and a connecting portion 11 in which an elongated guide groove 10 is formed. The stud engaging part 9 supports the connecting part 11 and is formed in a cylindrical shape so as to surround the stud 8 (Fig. 1). The stud insertion hole 13 has a diameter enlarged enough to accommodate the stud insertion hole 13 and has a blind hole at the top, and the inserted stud 8.
A locking pawl 14 protrudes inward to engage with the thread of the locking pawl 14, and an insertion hole 13 above and below the locking pawl 14.
It has a through hole 15 extending along.

The through hole 15 is a hole necessary for molding the locking pawl 14, and facilitates molding of the locking pawl 14. In particular, when slits 16 (FIG. 3f) are formed on both side edges of the locking pawl 14 to increase the elasticity of the locking pawl 14, the through hole 15 facilitates the formation of the slit 16. By forming this slit, the elasticity of the locking pawl 14 is maintained while the stud insertion hole 13 is inserted.
The diameter of the stud can be made slightly larger than the outer diameter of the stud, thereby preventing the stud engaging portion 9 from wobbling relative to the stud 8.

Preferably, three locking claws 14 are provided along the periphery of the stud insertion hole 13 so as to engage with three locations on the circumferential surface of the thread of the stud 8. The adhesion force to the stud 8 is strengthened. As shown in FIG. 3e, each of the locking claws 14 is inclined upward, so that it can be easily inserted into the stud 8, but it will not come off from the stud. As mentioned above, slits 16 are formed on both side edges of the locking pawl 14, thereby providing the necessary flexure during insertion.

The connecting part 11 has a pair of guide rails 18, 18 forming an elongated groove 10, the groove 10 being closed at one end and the open end being closed at the end of the groove 10, as shown in FIG. 3c. It is formed into a tapered shape, and a stopper 19 is cantilevered below the stopper 19 so as to extend toward the groove. Additionally, a third stud is provided between the stud engaging portion 9 and the rail 18 on the side closer to the stud engaging portion 9.
An elongated recess 20 parallel to the groove 10 as shown in Figure b
is formed. Further, in the lower part of the rails 18, 18, as shown in FIG. 3e, an elongated recess 21 having a width wider than the guide groove 10 is formed. Protrusions 2 each forming two peaks are provided at approximately mid-length positions on the inside of the rails 18, 18 forming the guide groove 10.
2 is provided. Note that the recesses 23, 23 are for weight reduction.

In FIGS. 4a to 4d, the wire holding component 3 includes an arm 4 that supports a bundle of wires over a predetermined length, and a main body 25 that supports this arm 4 approximately in the middle. Each of the protrusions 26 is provided to prevent the wires supported by the tape 5 from slipping. The arm 4 is preferably formed to have an L-shaped cross section in order to maintain high strength.

As shown in FIG. 4b, the main body 25 is equipped with a T-shaped pin 29 consisting of a shaft portion 27 with a diameter that can slide in the guide groove 10 of the connecting part 6 and an enlarged head portion 28. 3 are formed with guide pieces 30, 31 which are formed in a substantially U-shaped shape and slide on the outside of the guide rails 18, 18 (FIG. 3). The outer guide piece 31 is shortened so that it slides in the recess 20 of the connecting part 6. Also, the head 2 of the pin 29
The diameter of 8 is larger than the width of the guide groove 10 of the connecting part 6, but slightly smaller than the width of the elongated recess 21 therebelow.

The electric wire holder 2 having such a configuration is shown in FIG.
As shown in b, the connecting part 6 and the wire holding part 3 are used in an assembled state. To assemble, insert the pin 29 of the wire holding part 3 into the guide groove 10 of the connecting part 6.
This is done by inserting it from the open end of the When the pin 29 is inserted following the taper 24 of the rail 18 (FIG. 3c), the stopper 19 bends outward, and when it is pushed further, the stopper 19 returns to its original state, preventing the pin 29 from detaching from the guide groove 10. be done. Part 3 is thus connected to part 6. Note that guide piece 3
0 and 31 press down the guide rails 18 and 18 from the outside, so the connection strength after installation is high. After this connection, push the pin 29 deep into the guide groove 10 and
When located in the valley of the double protrusion 22, the connecting position of both parts is fixed, and therefore the protrusion 22 acts as a temporary fixing member. This situation is shown in Figure 2a. If this holder is delivered to the user in this state, there will be no loss of one of the parts, and troubles due to parts shortage can be avoided.

Next, as shown in FIG. 1, a bundle of electric wires 1 is supported by a tape 5 on the arm 4. On the other hand, a threaded stud 8 is fixed to a predetermined location on the vehicle body 7, and the stud engaging portion 9 of the connecting portion 6 is inserted through the stud 8 to fix the electric wire 1 to the vehicle body 7.
Since the wires are fixed at multiple locations rather than at one location, pitch deviations often occur. In this case, the pin 29 of the wire holding component 3 should be
2 in the direction of the arrow in FIG. 1 to absorb the pitch deviation.

The above method for attaching the wire holder is merely an example, and other methods may be used. For example, the retainer 2 may be attached to the stud first and the wire held later, or only the connecting part may be attached to the stud, the wire may be attached to the wire retaining part on the other hand, and then both parts may be connected. Good too. Note that removal is performed in the reverse order of the above installation method, but the connecting parts can be removed by rotating them, and the wire holding parts can be removed from the connecting parts by bending the stopper outward and pushing the pins. All you have to do is slide it.

Effects of the invention According to the invention, the wire holding part and the connecting part are connected, and since both parts are connected at the sliding part, one part can be moved relative to the other part while being connected, and this allows the pitch Correction of deviations is extremely easy. According to the wire holder of the present invention, a protrusion is provided at a longitudinally intermediate position inside the guide groove to abut against the side surface of the pin shaft and to anchor the pin at that position. Therefore, if there is no misalignment between the pitch of the mounting holes and the pitch of the connecting part of the wire holder holding the wire, there is no need to adjust the position of the wire holding part with respect to the connecting part, and this makes the installation work easier. This reduces man-hours and eliminates cost increases. Furthermore, according to the wire holder of the present invention,
One end of the guide groove is closed, and a stopper is formed at the open end of the guide groove between the pair of guide rails, so the rigidity of the guide groove portion is increased, and therefore the wire is held in place. That becomes certain.
