Abstract

PURPOSE: To eliminate the looseness of harness effectively while maintaining excellent workability so as to prevent the severance of wire. CONSTITUTION: A fitting body 12 fixed to a vehicle body is provided with a harness holding part 13 slidably. The harness holding part 13 holds harness slidably, and is energized by a spring 16 provided at the fitting body 12. The harness held by the harness holding part 13 is thereby energized in the elongaged direction so as to be prevented from becoming loose.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harness clamp used for preventing loosening of a harness (a plurality of wires bundled with an insulating tape or the like) in vehicle wiring.

[0002]

2. Description of the Related Art Conventionally, in the wiring of an automobile, each harness has a length slightly longer than a required size from the viewpoint of improving workability in an assembly line or improving replaceability of parts thereafter. .

For example, as shown in FIG. 6, a rear lamp 1
The harness 2 connected to the vehicle is sized so as to project from the through hole 4 formed in the rear portion of the vehicle body 3 so that the harness 2 and the rear lamp 1 can be connected outside the vehicle body 3. (See FIG. 5 (a)). After the harness 2 is connected to the rear lamp 1, the rear lamp 1 can be attached to the vehicle body 3 by pushing the harness 2 into the vehicle body 3.

[0004]

However, as described above, if the harness 2 is made longer than necessary, workability and the like are improved, but conversely, due to the looseness of the harness 2, the harness 2 is placed inside the vehicle body 3. When pushing in the harness 2, the harness 2 may be bent, or when the rear lamp is attached to the vehicle body 3, the harness 2 may be caught between the vehicle body 3 and the rear lamp 1, and the harness 2 may be broken. (See FIG. 5 (b)).

In view of the above problems, the present invention provides a harness clamp capable of effectively removing looseness of the harness and preventing disconnection thereof while maintaining excellent workability. To aim.

[0006]

In order to achieve the above object, according to the present invention, a harness holding portion in which a harness is slidably held and a harness holding portion fixed to a vehicle body are slidably held. Then, the mounting main body is provided with a biasing means for biasing the harness held via the harness holding portion in the extending direction.

[0007]

According to the structure of the present invention, when the harness is slidably held in the holding portion, the harness is wired and the electrical components are connected, and then the electrical component is attached to the vehicle body, the harness is attached. The biasing means pulls the harness in the extending direction through the harness holding portion, so that the slack does not occur.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 4 show a clamp 11 for a harness according to the present invention. This harness clamp 11
Is generally composed of a mounting body 12 fixed to the vehicle body 3 and a harness holding portion 13 slidably mounted on the mounting body 12.

The mounting body 12 is substantially plate-shaped, and grooves 14 are provided in parallel on both sides of the upper surface. In each groove portion 14, a rail portion 15 is extended from the upper edges of both side surfaces of a protruding portion formed between both groove portions 14, and a spring 16 is housed therein. Further, the end portion 12a of the mounting body 12 is attachable / detachable, and the end surfaces of the both groove portions 14 can be opened / closed. Further, at two locations on both ends of the bottom surface of the mounting body 12, engagement portions 16 are press-fitted into the mounting holes 10a formed in the vehicle body 10.

The harness holding portion 13 is made of a plate material having a substantially U-shaped cross section, and is rotatable as a support shaft 17 in the central portion. A shaft portion 18 is provided upright in the center of one end side of the harness holding portion 13, and a ring 19 is rotatably mounted around the shaft portion 18, as shown in FIG.
An engagement groove 18a is formed along the circumferential direction at a position of a predetermined dimension from the upper end of the shaft portion 18. On the other hand, an engaging hole 20 through which the tip of the shaft portion 18 is inserted is formed in the center portion on the other end side of the harness holding portion 13. The engaging groove 18a is inserted into the inner peripheral surface of the engaging hole 20 with the shaft portion 18 inserted therethrough.
An engaging protrusion 20a that engages with and holds the harness holding portion 13 in a substantially U-shaped cross section.

A slide portion 21 is formed on the bottom surface of the harness holding portion 13 by extending downward from both sides and then extending in opposite directions. The slide portion 21 slides in the groove portion 14 so as to hold the rail portion 15 formed on the mounting body 12.

In the harness clamp 11 having the above-described structure, the spring 16 is housed in both the groove portions 14 from the end face side before the end portion 12a of the mounting body 12 is mounted, and then the harness holding portion 13 is slid on the harness holding portion 13. The rail 21 holds the rail 15 and pushes the rail 15 slidably against the biasing force of the spring 16. Subsequently, by attaching the end 12a of the attachment body 12, the harness holding portion 1
3 is prevented from falling off, and the engaging portion 16 of the mounting body 12 is press-fitted into the mounting hole 4 formed in the vehicle body 3.

When the harness clamp 11 is attached to the vehicle body 3 at a predetermined position in this manner, the wiring of the vehicle is performed. In this wiring work, the harness 2 is arranged around the shaft portion 18 enclosing the ring 19 in a state where the harness holding portion 13 is expanded as shown by the chain double-dashed line in FIG. And
By rotating the support shaft 17 as a center and inserting the tip of the shaft portion 18 into the engagement hole 20, the engagement protrusion 20a is engaged with the engagement groove 18a. As a result, the harness 2 is
As shown by the solid line, the harness holding portion 1 has a substantially U-shaped cross section.
3 and a ring 19 rotatably mounted on the shaft portion 18 so as to be slidably held.

Then, the harness 2 is pulled and wired. In this case, the harness holding portion 13 has the spring 16
Is moved in the direction of compressing, and the urging force of the spring 16 acts on the harness 2.

Then, the connector 2a provided on one end side of the harness 2 is projected from, for example, a through hole 4 formed in the rear vehicle body 3. At this time, the position of the connector 2a is regulated by a holder (not shown) so that the connector 2a can be kept protruding from the rear vehicle body 3. Then, the vehicle body 10
The rear lamp 1 is connected to the harness 2 protruding from the connector 2a via the connector 2a, the holder is removed, and the rear lamp 1 is fitted into the through hole 4 to complete the mounting operation.

In this mounting work, since the urging force of the spring 16 is applied to the harness 2 by the harness clamp 11 via the harness holding portion 13, the harness 2 is pulled by the removal of the holding tool. Receive and never loosen. Therefore, the rear lamp 1 is attached to the vehicle body 3
When installing it on the harness 2,
It will not be forcibly bent and there is no risk of breaking the wire.

[0017]

As is apparent from the above description, in the present invention, the harness holding portion slidably holds the harness and the biasing means pulls the harness in the extending direction. After installing the electrical components,
There is no slack in the harness, and the problem of wire breakage of the harness, which has been a problem in the past, can be effectively prevented.
