<Invention of Claim 3>
According to this configuration, since the locking portion composed of the string body and the bulging portion is arranged in the connector holder, the connector holder is moved by holding the string body with one hand, and the bulging portion at the tip of the string body is directly It can be held by inserting it into the insertion hole arranged in the electrical connection box, inserting the string body into the locking hole from the side, and locking the bulging portion to the edge of the locking hole. . That is, it is not necessary to use both hands as in the case of locking both ends of the conventional clip band, and the holding work can be facilitated.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS.
In FIG. 1, reference numeral 10 is an instrument panel as an interior panel of an automobile, and a harness 11 is assembled on the back surface of the instrument panel 10.
[0011]
The harness 11 is composed of a plurality of electric wires, and a plurality of terminal groups are formed by branching the plurality of electric wire groups from the electric wire groups. And the junction box 12 is provided in a predetermined | prescribed terminal part, and the several connector 13 is attached to several other terminal parts.
[0012]
Details of the junction box 12 are shown in FIG. 2, and a metal terminal 15 is fixed to a housing 14. The housing 14 is made of, for example, polypropylene (PP) to which glass fibers are added in order to improve heat resistance, and a pair of housings 14 has an upper edge in FIG. The arms 16 and 16 stand up. Then, a bolt (not shown) passed through a through-hole 17 formed at the tip of each arm 16 is screwed into, for example, the lower edge portion of the instrument panel 10, so that the junction box 12 is formed as shown in FIG. It is fixed to the housing 14.
[0013]
When the instrument panel 10 and the harness 11 are assembled and transported to an automobile assembly factory, the plurality of connectors 13 are accommodated in the connector holder 20. Details of the connector holder 20 are shown in FIGS. 3 (A) and 3 (B). The connector holder 20 is made of polypropylene (PP) not containing glass fibers, and has a container structure in which one surface of a rectangular parallelepiped is opened. A plurality of connector engaging portions 22 are provided on the inner wall of the recess 20 </ b> A of the connector holder 20, and the connectors 13 are fixed to the connector engaging portions 22.
[0014]
Now, the connector holder 20 and the junction box 12 are provided with a holding structure for holding them. This holding structure has a structure in which a bulging portion 24 is provided in a string 23 integrally formed with the connector holder 20 and the bulging portion 24 is locked in a locking hole 25 formed in the housing 14 of the junction box 12. . More details are as follows.
[0015]
From the opening edge of the recess 20 </ b> A provided in the connector holder 20, a flange 21 is formed so as to project sideways, and the string body 23 extends from the outer edge portion of the flange 21. In the plan view of FIG. 3A, the string body 23 rises from the flange 21 toward the side, is rounded, and is bent at a right angle to the left side of the figure, and the intermediate portion is parallel to one side of the connector holder 20. Thus, it is curved in the shape of a hairpin in the middle, and the tip portion also extends in parallel with one side of the connector holder 20. Further, in the side view shown in FIG. 3B, the string member 23 has a structure in which the rising portion extends from the flange 21 obliquely upward in FIG. Thus, the string body 23 has a curved structure, and the length is secured. On the other hand, the bulging portion 24 has a spherical shape, and is disposed at a position slightly proximal to the distal end of the cord body 23.
[0016]
On the other hand, the locking hole 25 has, for example, a long hole shape extending downward from the round insertion hole 26. The insertion hole 26 has a size that allows the bulging portion 24 to be inserted, and the locking hole 25 has a width that allows the bulging portion 24 to be inserted, but the string member 23 can be inserted from the insertion hole 26 side. Set to dimensions.
[0017]
Next, the operation of the present embodiment configured as described above will be described.
When the harness 11 is assembled and transported to the instrument panel 10, the plurality of connectors 13 provided at the end of the harness 11 are engaged with the connector engaging portions 22 provided in the connector holder 20. Thereby, the plurality of connectors 13 are held in a state of being accommodated in the connector holder 20. Then, in order to lock the connector holder 20 to the junction box 12, the connector holder 20 is moved to the junction box 12 side by holding the cord body 23 integrally formed with the connector holder 20. At this time, as shown in FIG. 4A, the string body 23 is pulled and stretched linearly. Then, the bulging portion 24 provided at the tip of the cord body 23 is inserted into the insertion hole 26, and the cord body 23 is shifted laterally into the locking hole 25 as shown in FIG. insert. Here, if the hand is released from the cord body 23, the cord body 23 is placed in the inner part of the locking hole 25 (the lower end in FIG. 4B) due to the weight of the connector holder 20, and bulges out. The portion 24 is locked to the edge of the locking hole 25. As a result, the string body 23 cannot be removed from the locking hole 25, and the junction box 12 and the connector holder 20 are connected by the string body 23.
[0018]
On the other hand, the connector holder 20 is removed from the junction box 12 at the transport destination. In this case, contrary to the above procedure, the string body 23 may be shifted above the locking hole 25 and the bulging portion may be aligned with the insertion hole 26 and removed.
[0019]
Thus, according to this embodiment, since the connector holder 20 is connected to the junction box 12 by the string 23 integrally formed with the connector holder 20, the conventional clip band can be eliminated, and the number of parts can be reduced. Figured. Further, since the locking can be released by a procedure reverse to the above procedure, no dust is generated as in the case of cutting the conventional clip band, and a cutting tool is not required. Moreover, since the cord body 23 is arranged on the connector holder 20 side of the junction box 12 and the connector holder 20, the cord body 23 is held with one hand in order to move the connector holder 20, and the distal end portion of the cord body 23 is expanded as it is. The exit portion 24 can be inserted into the insertion hole 26 formed in the junction box 12 to perform a holding operation. Therefore, it is not necessary to use both hands as in the case of locking both ends of the conventional clip band, and the holding work can be facilitated. In addition, the connector holder 20 does not require heat resistance as compared with the junction box 12 and is made of a relatively soft synthetic resin (polypropylene not containing glass fibers). Can do.
