BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle harness guiding device mainly used for a turn signal switch for an automobile.

[0002]

2. Description of the Related Art Conventional techniques are described with reference to FIGS.
This will be described with reference to FIG. FIG. 4 is an exploded perspective view of a main part showing a mounting portion of a conventional vehicle harness guide device, FIG. 5 is a perspective view of a turn signal switch to which the device is mounted, and FIG.
(A)-(d) is principal part sectional drawing which shows the attachment process of the same apparatus.

According to FIG. 1, reference numeral 10 denotes a turn signal switch to which a turn signal lever 12 and a wiper lever 13 are attached, and the turn signal switch 10 and the vehicle side are electrically connected by a harness 14.
Reference numeral 15 denotes a case capable of storing the harness 14 in a loop shape, and absorbs expansion and contraction of the harness in a steering having a tilt or telescopic mechanism. 11
Is a main body serving as a base of the turn signal switch 10. The main body is provided with two square holes 11a and 11b, and the two square holes 11a and 11b are provided with surfaces 11c and 11d. Reference numeral 16 denotes an L-shaped harness clamper for holding a harness 14 electrically connected to the turn signal switch 10. Two elastic claws 16 a and 16 b are aligned with the square holes 11 a and 11 b of the main body 11. They are arranged in a 90 ° direction. Elastic claw 16a, the 16b, missing
Surface 16c for preventing, 16d is is provided with, disconnect of the body 11
It is constituted so that it may fit with surfaces 11c and 11d for stopping . Reference numeral 17 denotes two angular projections 17a and 17b.
The screw hole 17c is provided so that the holder can be attached to the main body 11 with the screw 18. Therefore, when attaching the harness clamper 16 to the main body 11, the elastic claws 16a and 16b are fitted into the square holes 11a and 11b provided in the main body 11 as shown in FIG. 6), the elastic claws 16a and 16b are inserted, and the elastic claws 16a and 16b are bent.
As shown in (c), for retaining the square holes 11a and 11b .
Surface 11c, 11d and the elastic pawls 16a, 16b of the stopper of the
Surface 16c of use, 16d comes to fit. In this state, when a force is applied to the harness clamper 16, the elastic claws 16a and 16b are easily detached, so that the elastic claws 16a and 16b and the square holes 11a and 11b are formed as shown in FIG.
By inserting the convex portions 17a, 17b of the holder 17 into the space portions 19a, 19b formed by b, the elastic claws 16a, 16b are configured to be prevented from moving in the direction of the space portions 19a, 19b and coming off. At the same time, the harness clamper 16 is mounted on the main body 11 by further attaching the holder 17 to the main body 11 with screws 18, thereby constituting a vehicle harness guide device.

[0004]

However, in the above-described conventional vehicle harness guide device, after the harness clamper 16 is attached to the main body, it is necessary to hold the harness clamper 16 with the holder 17 so as not to be easily removed. There was a problem that the number of work steps required. In addition, since the joint between the main body 11 and the harness clamper 16 is too strong, when the driver's knee hits the column cover in a vehicle accident, it is an obstacle to reduce the impact on the knee.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a resilient projection of a harness clamper.
A protrusion for preventing disengagement is provided at the tip of the claw portion, and a concave portion for preventing disengagement is provided for the square hole of the main body so as to increase the degree of fitting between the main body and the harness clamper. .

[0006]

Therefore, according to the present invention, the degree of coupling between the elastic claws of the harness clamper and the square holes of the main body is increased, so that the harness clamper does not come off from the main body during normal use, and the vehicle has If a strong force generated when the driver's knee hits the column cover in an accident is applied to the harness clamper, the harness clamper comes off and can reduce the impact on the driver's knee. Since no holder and screws are required,
This has the effect of reducing the number of work steps and the number of parts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the vehicle harness guide device of the present invention will be described with reference to FIGS.

FIG. 1 is an exploded perspective view of a main part showing a mounting portion of a harness guide device, FIG. 2 is a perspective view of a turn signal switch to which the device is mounted, and FIGS. 3 (a) to 3 (c) are mounting of the device. It is principal part sectional drawing which shows a process. Note that the same parts as those in the related art will be described with the same reference numerals.

Referring to FIG. 1, reference numeral 1 denotes a main body serving as a base of the turn signal switch 10, and two square holes 1a and 1 are provided.
b is provided with retaining surfaces 1c and 1d. Further, the square holes 1a and 1b are provided with concave portions 1e and 1f for preventing detachment . Reference numeral 2 denotes an L-shaped harness clamper for securely guiding the harness 14 from the turn signal switch 10 , the direction of insertion into the square holes 1 a and 1 b of the main body 1.
Two elastic projections 2g, 2h in the same direction ,
They are arranged in a 90 ° direction in accordance with the positions of the square holes 1a and 1b of the main body 1. The tips of the projections 2g and 2h are
When the claw portions 2a and 2b are provided in a direction perpendicular to the insertion direction,
Are provided with retaining surfaces 2c and 2d . further
Claws 2a, 2b come off at the tip end in the opposite direction to the insertion direction
Protrusions 2e and 2f for prevention are provided. Therefore, when attaching the harness clamper 2 to the main body 1 , FIG.
As shown in (a), square holes 1a, 1
3b, the claws 2a, 2b at the tips of the protrusions 2g, 2h are fitted, and the claws 2a, 2b are pushed in as shown in FIG. 3 (b), whereby the claws 2a, 2b are at the bases of the protrusions 2g, 2h. From the portion , the dimension A becomes the dimension A ', and the dimension becomes the dimension B or more. As shown in FIG. 3 (c), the square holes 1a and 1b are prevented from coming off.
The mating surfaces 1c, 1d and the retaining surfaces 2c, 2d of the claws 2a, 2b are fitted. In this state, the protrusion 2 provided at the tip of the claw portions 2a and 2b of the harness clamper 2
e, 2f fit into the recesses 1e, 1f provided in the main body 1 so that the relationship of dimension A <dimension B is established.
Is configured so as not to come off from the main body 1 with a normal force. The material of the harness clamper 2 is the claws 2a, 2b.
Polypropylene resin is used to remove large deflection. Further, if a strong force generated when the driver's knee hits the column cover or the like is applied to the harness clamper 2 in a vehicle accident, there is no portion that blocks the bending of the claw portions 2a and 2b. Is the body 1
It will be more off.

In this embodiment, the harness clamper 2
Are provided with claws 2a and 2b, but the main body is provided with claws ,
A configuration in which a square hole and a concave portion are provided in the harness clamper is also possible.

[0011]

According to the present invention, as is apparent from the above embodiment , the tip of the claw of the elastic projection of the harness clamper is used.
A convex portion for preventing detachment is provided at the end, and a concave portion that engages with the convex portion for preventing detachment is provided in a square hole of the main body, so that the coupling strength between the harness clamper and the main body is high, and in normal use, If the harness clamper does not come off from the main body and a strong force that is generated when the driver's knee hits the column cover in a vehicle accident, etc., acts on the harness clamper, the clamper comes off and the driver's knee is released. This has the effect of reducing the impact on the vehicle. In addition, when the clamper is mounted, parts such as a holder and a screw are not required, so that there is an effect that mounting workability is improved.
