BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a cable clamp and a cable protection cover for cables wired to a circuit board.

[0002] In order to protect optical fiber cables (hereinafter abbreviated as optical cables) wired to optical circuit boards mounted on optical communication equipment from damage during maintenance work, clamps are used along the wiring route of the optical cables. There is a need for safe protection.

2. Description of the Related Art As shown in the perspective view of FIG. 3, a conventional cable clamp 11 is made of a molded synthetic resin material, and is elastically closed in a U-shaped (C-shaped) band body 11a. It has an opening 11a-1, and the mounting surface is integrally molded with a mounting engagement protrusion having a claw at its tip that engages the mounting means 11b, that is, the circuit board.

The conventional cable protection cover mounting structure is as shown in the partially exploded perspective view of FIG.
The cable clamps 11 are inserted into and engaged with the engagement holes 12a that are drilled at key points along the wiring route of the optical cable 13 wired in the optical cable 2, and the opening is opened to insert and hold the optical cable 13, and to remove the excess cable. A cable protection cover 14 covering the long portion is attached by tightening mounting screws 15 from the opposite side.

[Problem to be Solved by the Invention] However, according to the above-mentioned cable clamp and cable protection cover mounting structure, although the cable clamp has a cable holding function, it does not have the function of attaching the cable protection cover. , it is necessary to separately drill mounting holes on the circuit board and attach the cable protection cover, and when mounting holes are drilled on the circuit board, the wiring pattern and the mounting hole position are mutually constrained, and the mounting hole position is There was a problem in that the shape of the cover was constrained when the cover was constrained.

In view of the above problems, the present invention provides a cable clamp and a cable protection cover that can hold cables wired to a circuit board and also allow the cable protection cover to be attached without depending on the wiring pattern in the mounting hole position or shape. The purpose is to provide a mounting structure for.

[0007]

[Means for Solving the Problems] In order to achieve the above object, in the cable clamp and cable protection cover mounting structure of the present invention, the cable clamp has a synthetic resin band body for inserting and holding the cable on the mounting surface. The mounting surface is provided with a mounting means, and the mounting means is also provided protrudingly on a surface other than the mounting surface. In addition, the mounting structure of the cable protection cover has a plurality of cable clamps, one mounting means is attached to the circuit board along the cable wiring route, and the other mounting means has an engagement hole corresponding to the cable. It consists of a cable protection cover formed in a shape that covers the wiring route.

[0008]

[Function] In addition to the attachment means for attaching to the circuit board, the cable clamp is equipped with the attachment means for attaching the cable protection cover, so that the cable clamp can insert and hold the cable wired on the circuit board. Since the cable protection cover can be attached to the cable clamp without drilling any other mounting holes, the mounting hole position and shape of the cable protection cover are no longer restricted by the wiring pattern of the circuit board. The cable can be formed into a shape that covers the cable along the wiring route regardless of the mounting position.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The gist of the present invention will be explained in detail below based on embodiments shown in the drawings. As shown in the perspective view of FIG. 1, the cable clamp 1 is made of a molded synthetic resin material, and includes a U-shaped (C-shaped) band body 1a and an opening 1a-1 that closes elastically. , attachment means 1b, 1c are mounted on the mounting surfaces provided on both sides of the opening 1a-1, that is, the lower mounting surface has a mounting engagement protrusion 1b-1 with a claw at the tip for engaging the circuit board, and the upper The mounting surface has a mounting engagement protrusion 1c with a similar claw at the tip to engage the cable protection cover.
-1 by integral molding.

In order to hold an optical cable using this cable clamp, as shown in the partially exploded perspective view of FIG.
The cable clamp 1 is inserted into and engaged with the engagement hole 2a drilled at key points along the wiring route of the optical cable 3 wired on the circuit board 2, and the opening is opened to insert and hold the optical cable 3.

The mounting structure of the cable protection cover is as shown in FIG. 2, which is formed in a shape that covers the optical cable 3 along the wiring route, and has an engagement hole 4a that corresponds to the attachment projection 1b-1 of the cable clamp 1. A cable protection cover 4 is prepared, and the engagement hole 4a is inserted into the attachment engagement protrusion 1b-1 and engaged.

[0012] As described above, by providing an attachment means for attaching a cable protection cover to a conventional cable clamp, for example, an attachment engagement protrusion (or a screw fixing means) as in this embodiment, the circuit board can be attached to the cable clamp. It is possible to hold optical cables routed along the wiring route, and the cable protection cover can be formed into a shape that follows the wiring route and installed without being affected by the wiring pattern or mounting position of the circuit board. The cable to be protected can be covered and safely protected. In addition, the cable protection cover can be installed in a shape that covers only the optical cable.
With such a shape, other mounted components can be easily inspected without removing the cable protection cover.

In the embodiment of the cable clamp described above, the means for attaching the cable protection cover is provided on the U-shaped (C-shaped) band body. It is sufficient to provide a means of attachment. For example, a locking or screwing means may be attached to a gate-shaped clamp body that straddles the optical cable. Furthermore, it goes without saying that the cable clamp of the present invention can be applied not only to optical cables but also to other electric wires.

[0014]

[Effects of the Invention] As detailed above, according to the present invention,
Since the cable clamp can hold the cable and attach the cable protection cover, the mounting position and shape of the cable protection cover are no longer restricted by the wiring pattern, and can be formed into a shape that follows the cable wiring route. cables can be safely protected. It is particularly effective when applied to protect optical fiber cables that are easily damaged.
