Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite clamp and a clamping method used for laying cables such as operation cables.

[0002]

2. Description of the Related Art When laying an operation cable such as a push-pull cable or a pull cable to a device such as a vehicle, two or more types or two or more clamps are used because of the necessity of a three-dimensional wiring route. There is a case. The use of the plurality of clamps requires a great deal of force for cable arranging, requires a plurality of attachment points, and increases the arranging space and the number of assembling steps. Therefore, it is desired to substitute one composite clamp. .

[0003]

The composite clamp in which a plurality of clamps are replaced by one has a complicated three-dimensional structure in the central axis of the cable near the composite clamp, which makes it difficult to insert and set it in a device after the cable is assembled. May be In this case, there is no choice but to omit the cable length check for checking the cable length when the device is attached to the device and the pretension for tensioning the cable in order to remove the initial elongation. For this reason, it is a great obstacle in maintaining the functional quality of the cable.

An object of the present invention is to use a single clamp, which originally requires two or more, to clear route regulation and interference countermeasures, and to combine cable clamps and clamps for easy cable length inspection and pretensioning. It is in the provision of methods.

[0005]

The composite clamp of the present invention is a composite clamp for attaching a plurality of points of a cable or a plurality of cables to a device, the cable holding part, the mutual connecting part, and the device. The gist is that a plurality of clamps each having a mounting portion are connected by the mutual connecting portions.

[0006]

According to the present invention, one compound clamp can substitute for two or more clamps, which are usually required for three-dimensional wiring, route regulation and interference countermeasures. For this reason,
It is possible to reduce the formation and use of clamp mounting holes and screws in the body of the device, and to reduce the installation space and installation man-hours.

According to the second or third aspect of the invention, a plurality of clamps are sequentially attached to predetermined positions of the cable,
Performs cable length inspection and pretension. Next, while bending the cable into a predetermined three-dimensional structure, the connecting portions can be temporarily fixed and integrated, and then the attaching portion can be attached to the device. Therefore, it becomes easy to attach the composite clamp to the device, and the efficiency of the wiring work is high.
