Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a wire harness,
Further, the present invention relates to a unit case accommodating an electronic device, or a clamp structure of devices to a bracket used for attaching and locking a tangible article or the like to a bracket on a vehicle body side or the like.

2. Description of the Related Art Conventionally, there is a known example disclosed in Japanese Patent Application Laid-Open No. Hei 1-99719 as a clamp structure for locking a wire harness arranged on a vehicle body to a plate-shaped bracket on the vehicle body side. The clamp main part for winding and fixing the tape on is provided with a slot-shaped clasp part, and by the clasp piece extending inward from the upper and lower inner walls of the clasp part,
It has a structure in which a bracket on the vehicle body side inserted through the opening of the attached portion is clamped and the wire harness is clamped to the bracket on the vehicle body side.

[0003]

In the conventional clamp structure described above, the clamp portion of the wire harness side clamp is simply fitted into the bracket on the vehicle body side so that the wire harness bracket can be clamped to the bracket with one touch. Although it has the advantage that it can be done, its clamping force depends only on the holding force of the tongue-shaped holding pieces that press against the upper and lower surfaces of the plate-shaped bracket, so it is essentially weak, and the clamp may be disengaged due to vehicle body vibrations. There is a performance drawback.

The present invention solves the above-mentioned drawbacks of the prior art and provides a clamp structure for a device to a bracket which is excellent in clamp performance.

[0005]

SUMMARY OF THE INVENTION A clamp structure for a device to a bracket according to the present invention, which solves the above technical problems, comprises:
"In a clamp structure of a device to a bracket in which a plate-shaped bracket is inserted and locked in a clamp slot part on the device side and the bracket is mounted to the bracket, a slot wall on one side of the clamp slot part is fixed. A locking portion formed on an elastic locking piece of a cantilever that is elastically flexible in a direction orthogonal to the inserting direction, and further, a locking portion provided on a side portion of the elastic locking piece, and the locking portion The structure is provided with a retaining lock mechanism that is composed of the lock portion on the bracket side.

That is, in the clamp structure of the present invention, one side wall of the clamp slot portion for receiving the plate-shaped bracket is constituted by the elastic locking piece, and the bracket inserted into the clamp slot portion is pulled out of the above-mentioned manner. It is characterized by a structure in which devices such as a wire harness are attached and clamped to a bracket of a vehicle body or the like by locking the retaining lock portion to prevent it from coming off. Then, in order to facilitate the inserting operation and the locking operation for retaining, a mode is adopted in which a guide rib provided in the inserting direction of the clamp slot portion and a guide slit for receiving the guide rib are provided in the bracket. The devices in the present invention include wires / units such as a wire harness / electronic device unit, and accessories attached to a vehicle body or a mechanical device.

[0007]

In the above-described clamp structure for clamping a bracket of a device of the present invention, when a plate-shaped bracket of a vehicle body or a mechanical device is inserted into a clamp slot portion on the device side, a wall portion of the slot portion is formed. Since the locking part of the elastic locking piece and the lock part on the bracket side are engaged and prevented from coming off, the clamp locking performance of the equipment is stable, and there is no fear that the clamp will easily come off due to vibration of the vehicle body or the like. .
