Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fixture for easily fixing electrical wiring, etc. to a predetermined location.

[Conventional technology]

Conventionally, in the electrical wiring of automobiles, various electrical equipment, etc., these electrical wiring (hereinafter simply referred to as wiring) have been developed from the standpoint of improving workability or appearance when wiring harnesses or converging multiple electric wires. A fixing device is used to fix the device to the vehicle body or the wall of the equipment.

As this fixture, the one disclosed in Japanese Utility Model Application No. 51-3094 is known.

That is, as shown in FIG. 7 as a partially cutaway side view and as shown in FIG. A mounting hole a is provided, and a horizontal groove b perpendicular to the longitudinal direction of the fixture and a vertical groove c perpendicular to the horizontal groove b are provided on the other lower surface, one of the vertical grooves c facing the direction of the mounting hole a, The fixing member is configured to be connected to the through hole d toward the upper side of the fixture.

Therefore, to fix the wiring W to the fixture M, first screw the fixture M onto the mounting surface with the bolt e in the mounting hole a, and then use a band with an annular head f on one end and a ratchet g on the other side. This is done by passing the wiring W through the horizontal groove b or vertical groove c and the through hole d of the fixture M, and then integrally tightening the wiring W to the upper surface of the fixture M.

[Problem that the invention attempts to solve]

However, with such conventional fixtures, when the band h is inserted into the head f and the wiring W is tightened, the band h moves freely, making the tightening work difficult. Since the position is not fixed, it is necessary to secure enough space around the fixture M for the tightening work. Furthermore, the tightening part of the band h is located on the upper surface of the wiring W, and the end of the band extends above the wiring W, resulting in a problem that the appearance after tightening is poor.

The present invention was devised by focusing on the problems of such conventional fasteners, and aims to provide a fastener that can improve the workability of band tightening and the appearance of the tightening part.

[Means for solving problems]

The present invention will be described in detail below with reference to the accompanying drawings, which illustrate embodiments.

Figure 1a is a plan view of the fixing device of the present invention, Figure 1b
FIG. 2 shows a perspective view of the tightening band.

In the figure, the fixture A of the present invention has a wire mounting part 2 bent at an acute angle with respect to the support 1 at the upper end of the support 1, and a fixing part 3 bent at the lower end of the support 1. A through hole 5 is provided in the bending part 4 of the electric wire placement part 2, and a through hole 6 is provided in the tip end 2a of the electric wire placement part 2, and a through hole 6 is provided in the bending part 4 of the electric wire placement part 2, and a through hole 6 is provided in the bending part 4 of the electric wire placement part 2, and a through hole 6 is provided in the tip part 2a of the electric wire placement part 2. Expanded section 7 on the facing back side
By forming , it is integrally constructed from a hard resin material or the like.

In this configuration, the wire mounting portion 2 is formed into a plate-like body with an arcuate concave upper surface so that the wiring W can be easily placed thereon, and the bending angle with respect to the support 1 is adjusted to facilitate the tightening work. It is desirable that the angle be approximately 30-45°. In addition, through holes 5 and 6 are provided through the bent portion 4 and the tip portion 2a of the wire placement portion 2.
are holes through which the band portions 11 of band B are inserted, respectively;
It is formed in a shape and size that allows the band portion 11 to be easily inserted.

Further, an expanded portion 7 formed on the back side of the wire placement portion 2 facing the through hole 6 is a location where the head 12 of the band B is positioned, especially on the tip side of the wire placement portion 2. A taper 7a is formed so that the rear wall 12a of the head 12 can easily come into contact with the surface.

Further, the fixing part 3 formed at the lower end of the column 1 is provided with a mounting hole 8 for screwing the fixture A with a bolt or the like, but instead of the mounting hole 8, a known clip or other suitable mounting means can be used. can be provided.

Note that 9 and 10 are reinforcing walls of the wire placement part 2 and the fixing part 3, respectively.

On the other hand, band B has a belt part 11 having a ratchet part 11a on one side and a head part 1 formed at one end of the belt part 11.
2, a through hole 13 through which the band part 11 is inserted is provided through the head 12, and a locking protrusion 12b facing the through hole 13 and into which the ratchet part 11a of the band part 11 is locked is formed. has been done.

[Effect]

As shown in FIG. 3, the through hole 6 of the fixture A
The band B is inserted in advance from the back side of the wire placement part 2, and then the fixing part 3 is fixed in a predetermined position in the mounting hole 8 by means such as screwing. In this state, the wiring W is placed on the upper surface of the wire placement part 2, and the band part 11 of the band B is wound while converging the wiring W. Then, the wiring W is placed from above the bending part 4 and downward into the through hole 5. let it roll out.

Next, the band portion 11 is inserted from its tip to the through hole 13 of the head portion 12 of the band B located near the expanded portion 7.
By inserting the head 12 through and pulling it, the rear wall 12a of the head 12 is engaged with the tapered part 7a of the expanded part 7. At the same time, the ratchet surface 11a of the band portion 11 is engaged with the engagement protrusion 12b of the head 12, and the tightening of the wiring W is completed. FIG. 4 shows a state in which the wiring W is fixed using the fixture A of the present invention.

[Other Examples]

FIG. 5 shows another embodiment of the fixture of the present invention.

Fixture A' of this embodiment has the same structure as the above-mentioned fixture A in terms of its main body, but a band portion 1 of band B is attached to the end surface 2b of the wire placement portion 2.
A holding portion 14 that holds 1 is formed. The holding portion 14 may be formed by a pair of clamping pieces as shown in FIG. 6, or may be formed into a tunnel shape or other appropriate means. When providing the holding part 14 in this way, as shown in the figure, the through hole 6
By further passing the band portion 11 of the band B inserted upward through the holding portion 14, the band B can be integrally attached to the fixture A' in advance.

The band B attached to the holding part 14 is tightened to the wiring W in the same manner as described above after the band part 11 is pulled out from the holding part 14 when tightening the wiring W.

[Effect of idea]

The fixing device of the present invention has the structure and function described in detail above, and when tightening the wire with the band, the band head engages and fixes the expanded portion of the wire placement section, so it can be easily tightened with one hand. It is possible to significantly improve workability for converging and fixing wiring. Further, when the fixing device is provided with a band holding portion, the above-mentioned workability is further improved.

Further, since the locking portion between the head of the band and the band portion is located on the back side of the wire placement portion, there are advantages such as improved appearance after the wire is tightened.
