Abstract

(57) [Summary] [Purpose] To provide a bush capable of sufficiently transmitting the clamping force of a clamp fitting to a cord. [Construction] A window 8 is provided in a clamp stop portion 7 of a cylindrical body 2 which fits a cord. The cord is directly clamped by inserting the clamp claw of the clamp metal fitting from the window 8 into the inside.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bush that protects a lead-out portion of a cord from an electric device.

[0002]

[Prior Art]

 Conventionally, at the lead-out portion of the cord from the electric device such as a connector, a rubber bush is fitted to the lead-out portion of the cord from the housing of the electric device, and the bush is a part of the clamp in the longitudinal direction. The stopper was clamped with a clamp metal fitting to fix the bush to the cord, and the bush was locked to the housing with a clamp metal fitting to prevent the cord from being pulled out.

[0003]

[Problems to be solved by the device]

 However, conventionally, since the clamp metal fitting clamps the cord through the bush, the clamping force of the clamp metal fitting cannot sufficiently act on the cord, resulting in insufficient cord clamping.

An object of the present invention is to provide a bush capable of sufficiently transmitting the clamping force of the clamp fitting to the cord.

[0005]

[Means for Solving the Problems]

 A feature of the present invention for achieving the above object is that in a bush in which a clamp portion is provided in a part of a tubular body, a window in which a part of a clamp metal fitting is inserted in the clamp portion of the tubular body. Is provided.

[0006]

[Action]

 When the bush is clamped to the cord by the clamp fitting fitted to the outer circumference of the cord and fitted to the clamp fixing portion of the bush, a part of the clamp fitting is pushed in through the window of the bush, Clamp the cord directly. Therefore, the clamping force of the clamp fitting directly acts on the cord, and the bush can be firmly fixed to the cord.

[0007]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 to 4 show an embodiment of the bush 1 according to the present invention.

The bush 1 is made of rubber and has a tubular body 2, and an oval flange 3 is integrally provided at one end of the tubular body. On the outer periphery of the other end side of the cylindrical body 3, convex ring portions 4, 5 and 6 are integrally provided at predetermined intervals. A clamp portion 7 is provided between the flange 3 and the convex ring portion 4. The clamp stop 7 is provided with windows 8 opposite to each other in the circumferential direction.

5 and 6 show examples of the connector 9 using the bush 1 of this embodiment. The connector 9 has a connector housing 10, a plurality of connectors 11 are incorporated in one end of the connector housing 10, and a cord penetrating cylinder portion 12 is provided in the other end.

On the circumference of the cord penetrating cylinder portion 12, flanges 13 and 14 are integrally projected. A connecting claw 15 is projected from the flange 13 at a predetermined distance, and the connector housing 10 divided into two is connected by the connecting claw 15.

The bush 1 described above is fitted to the outer periphery of the cord 16 which is passed through the cord penetrating cylinder portion 12. A C-shaped clamp metal fitting 17 is fitted to the clamp stop portion 7 of the bush 1, and the bush 1 is clamped to the cord 16 by tightening the clamp metal fitting 17. In this state, the clamp metal fitting 17 clamps the cord 16 directly by inserting the clamp claw 17a on the inner circumference into the bush 1 through the window 8 of the bush 1.

The bush 1 clamped to the cord 16 in this manner is fitted and locked to the cord penetrating cylinder portion 12. That is, the flange 3 of the bush 1 is installed between the connecting claw 15 and the flange 13, the clamp metal fitting 17 is installed between the flanges 13 and 14, and is locked so as not to come off. The cord 16 is led out of the connector housing 10 to protect the cord 16.

In this case, when the cord 16 protruding from the connector housing 10 is bent, the lead-out portion of the cord 16 from the connector housing 10 is protected by the cylindrical body 2 of the convex ring portions 4 to 6. Since the clamp stop portion 7 enters the cord penetrating cylinder portion 12 and no bending force is applied thereto, the window 8 is opened in the cylinder body 2 so that the clamp claw 17a of the clamp metal fitting 17 directly bites into the cord 16. There is no hindrance.

[0015]

[Effect of the device]

 As described above, in the bush according to the present invention, the window is provided in the clamp portion of the cylindrical body, and the cord can be directly clamped by the clamp metal fitting by allowing a part of the clamp metal fitting to enter through the window. The bush can be firmly clamped to the cord, the cord is prevented from shifting axially in the bush, and the cord is securely fixed to the housing.
