DESCRIPTION OF THE PREFERRED EMBODIMENTS The following is a specific example of the wiring harness holder element of the present invention and the wiring harness holder of the present invention using the specified wiring harness holder element. The specified example will be described with reference to the drawings. FIGS. 1-3 show a wiring harness holder element embodiment 10 and a wiring harness holder embodiment of the present invention wherein the cab 42 is applied to a heavy truck 40 which is tiltable on the chassis 41. Example 20 is shown. The wiring harness holder 20 is connected to the wiring harness holder 20.
Many of the harness holder elements 10 are assembled in a zigzag hinged manner with pins 21 and the heavy truck 40 includes an anti-lock brake system (not shown), an electronically controlled auto transmission (not shown). ), An electronic control engine controller (not shown), and the like, and a computer 30 for controlling them are arranged in the cab 42, so that the wiring harness holder 20 Is utilized in the wiring harness 31 which electrically connects to the solenoid valves and sensors of the cab 42 and the relative movement between the cab 42 and the chassis 41, ie the cab 42
And the wiring harness 31 is supported between the chassis 41 and the cab 42.

As can be seen from FIG. 2, the wiring harness holder element 10 has a twist angle of 180.degree. About its axis so that the wiring harness 31 can be fitted. The helical pipe element 11 having a circular shape and the knuckle joints 12 formed integrally with both ends of the helical pipe element 11 having a semicircular cross section are integrally formed of resin.

[0008] The spiral pipe having a semicircular cross section
The element 11 has its knuckle joints 12, 1
2, an eye 13, 13 is drilled, and one of its knuckle joints 12, 12 is integrally formed with a helical pipe element 11 having a semicircular cross section of another wiring harness holder element 10. The other of the knuckle joints 12, 12 is assembled in a hole-aligned state, and pins 21 are attached to both eyes 13, 13.
And the pin 21 is hingedly fastened to the knuckle joints 12, 12 thereof with an E-ring 22. Similarly, the helical pipe element 11 having a semicircular cross section is formed by integrating the other of the knuckle joints 12 with the helical pipe element 11 having a semicircular cross section of another wiring harness holder element 10. One of the knuckle joints 12, 12, which are formed in a form, is fitted in an aligned state, a pin 21 is passed through both of the eyes 13, 13, and the pin 21 is connected to the two knuckle joints with an E-ring 22. It is stopped at joints 12 and 12 and hinged.

Next, in the large truck 40,
First, by repeating the above-mentioned hinge connection, as many wiring harness holder elements 10 as required for the tilt of the cab 42 are connected in a zigzag manner and assembled to the wiring harness holder 20. Can be

As shown in FIG. 3, the assembled wiring harness holder 20 has a spiral pipe element 11 having a semicircular cross section at each wiring harness holder element 10.
The wiring harness 31 is partially fitted to the two ratchet cable straps (Rat
(Cable Cable Strip) 23, 23.

The wiring harness holder 20 has a bracket (not shown) in which the wiring harness holder element 10 at one end thereof is positioned rearward of the front axle and is disposed on the chassis 41. ) Is hinged with a pin 21,
On the other hand, its wiring harness
The holder element 10 is hinged with a pin 21 to a floor bracket (not shown) arranged on the cab 42 corresponding to the chassis bracket.

[0012] The wiring harness holder 20 thus mounted is capable of absorbing the tilt of the cab 42 and passing the vicinity of the tilt center 43 between the chassis 41 and the cab 42 without passing near the tilt center 43. The wiring harness 31 is supported therebetween. Therefore, in the vicinity of the tilt center 43, interference due to the crowded connection means is reduced.

Although the wiring harness holder element 10 has been described as being formed from resin, the wiring harness holder element 10 may be pressed from a metal plate.

As will be apparent from the specific embodiments of the present invention described above with reference to the drawings, one of ordinary skill in the art to which the present invention pertains will appreciate the subject matter of this invention Is the nature of the invention (na
), and are readily embodied in other embodiments that are objectively perceived as inherent in them. Of course, the contents of the present invention are indispensable for the establishment of the invention corresponding to the subject of the invention.

[0015]

As will be understood from the above description, the wiring harness holder element of the present invention has a semicircular cross section which has an appropriate twist angle and allows the wiring harness and the cable to be fitted. A helical pipe element and knuckle joints integrally formed at both ends of the helical pipe element having a semicircular cross section, and the wiring harness holder of the present invention has an appropriate twist angle. And a helical pipe element having a semicircular cross-section that enables fitting of a wiring harness, a cable, etc., and knuckles integrally formed at both ends of the helical pipe element having a semicircular cross-section. Multiple wiring harness holder elements including joints Is connected in a zigzag manner by the knuckle joint of the wiring harness holder element and the wiring harness holder of the present invention. Harnesses and cables etc. can be routed, especially for tilt cab type trucks, so that wiring harnesses and cables etc. are avoided near the tilt center and are routed near the tilt center Interference due to jamming of various connection means is reduced, and as a result, it is very useful and practical for commercial vehicles.
