Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a cable holder that holds and fixes a cable fixedly attached to a board by disposing its end portion at a predetermined position on the board.

For example, when removing the insulating coating from the end of a cable such as a parallel wire feeder and installing and fixing the exposed core conductor through a predetermined mounting hole in the board at a predetermined position on the board, the cable is attached to the board. It is necessary to fix and hold the object without changing its position. In such cases, the conventional method is to bend the core conductor in the middle of the exposed core conductor of the cable to create a bent part, and to engage the cable with the board at this bent part to fix the cable. It had been taken. However, this conventional method of attaching the cable to the board is inevitably unstable when attached, and the attached cable may become detached, especially if a torsional force is applied to the attached cable from the outside. The problem is that it is easy.

This invention provides a cable holder that has a simple structure, allows easy operation of attaching a cable to a board, and can securely hold the cable attached to the board.

According to this invention, a plurality of cable insertion holes are formed along the longitudinal direction, and a base that can be fixedly attached to the board is provided. A fitting hole is formed on the end side of the base so as to be continuous with the cable insertion hole located on the longitudinal end side of the base, and a fitting hole is formed on the base near the fitting hole. A piece is formed, and this fitting piece is bent toward the insertion hole and elastically fitted to the insertion hole, and by fitting this fitting piece with the fitting hole, at least the end of the base The core wire of the cable inserted into the cable insertion hole located between the cables is elastically biased against the wall surface of the insertion hole, so that the cable can be fixed to the base.
