Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protection holder for an optical fiber cable which winds and stores the optical fiber cable.

In an optical communication device or the like, an optical circuit board is formed by winding an extra length of an optical fiber cable (abbreviated as an optical cable) wired on the board in a loop. When the optical circuit boards are arranged in the shelf and inserted / removed, the loop portion may be easily hooked on the adjacent board and may be broken.

Therefore, the protective cover for covering the loop portion is screwed, but if there are many mounting holes of the protective cover formed on the substrate, the wiring pattern is restricted, or conversely, the mounting holes are protected beforehand. There is a problem that the shape of the cover has to be adapted to it. In view of such a situation, there is a demand for an optical cable protection holder capable of holding and protecting the optical cable regardless of the position and shape of the mounting hole.

2. Description of the Related Art Conventionally, as shown in an exploded perspective view of FIG.
The optical cable 12 wired on the optical circuit board 13 is fixed by sandwiching the cable clamper 11 at several points, and a loop part with extra length is wound.
12a is also fixed by sandwiching the cable clamper 11 at several points. Then, cover the loop portion 12a with the protective cover 14,
The mounting foot 14a is attached by screwing it from the opposite surface with a mounting screw 15.

[0005]

However, according to such an optical cable holding and protecting structure as described above, the mounting hole of the cable clamper for holding and fixing the loop portion of the optical cable is formed corresponding to the loop diameter. There is a problem that the wiring pattern is affected, and the mounting hole of the protective cover that covers the loop portion similarly restricts the wiring pattern.

In view of the above problems, it is an object of the present invention to provide an optical cable protection holder capable of winding and holding and protecting an extra length of an optical cable in a loop and attaching it to a member to be attached at one place. To do.

[0007]

In order to achieve the above object, in the optical cable protection holder of the present invention, a cable holding piece that radially extends integrally is provided on the peripheral edge of the disk so as to project therefrom. A cable holding portion having a folded opening portion having a space is formed at the tip end, and a mounting means is provided at the shaft center.

[0008]

A ring-shaped enveloping space is formed by projecting a radial cable holding piece on the periphery of the disk and forming a cable holding portion having a space and a folding opening at the tip of the cable holding piece. It is possible to protect the optical cable by introducing the optical cable into / out of the ring-shaped envelope space from between arbitrary cable holding pieces and winding / holding the optical cable in the cable holding portion.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The gist of the present invention will be described in detail below with reference to the embodiments shown in the drawings. As shown in the plan view of FIGS. 1 (a) and 1 (b) and the sectional view along the line AA, the cable protection holder 1 is made of a synthetic resin molded product, and is radially integrated with the peripheral edge of the disc 1a. A plurality of extending cable holding pieces (1b) are provided in a protruding manner, the tip of the cable holding piece (1b) is lowered to the mounting surface side by one step, and then a U-shaped space is formed to fold it back. (1b
-1b is an opening thereof). Thereby, a ring-shaped envelope space is formed around the disc 1a to form a cable holding portion 1b-1 for holding the optical cable 3 in a wound manner. The size of the envelope space is the U-shaped bending depth (height) and its bending diameter (roll diameter).
It is determined by the extra length and the winding diameter of the optical cable 3. It should be noted that, in the case of folding the U-shape, contrary to the above, the tip of the cable holding piece may be raised to the side opposite to the mounting surface by one step and then folded back into the U-shape.

Further, the disc 1a is attached to the shaft center by a mounting means 1c,
That is, the mounting boss is integrally formed and provided with a mounting hole 1c-1 penetrating therethrough. The attachment to the attachment member 2 is performed with the attachment screw 4 and the nut 5.

In the case of an optical circuit board or the like in which the member 2 to which the cable protection holder 1 is attached generates heat, the disc 1a is used.
As shown in the figure, a plurality of ventilation holes 1a-1 are formed so as not to prevent air convection.

The optical cable 3 is introduced and led out between the cable holding pieces 1b, and is inserted and wound from the opening 1b-1b of the cable holding portion 1b-1. In this way, the radial cable holding piece is provided so as to project on the periphery of the disk, and the cable holding portion having a space at the tip of the cable holding piece and having the folding opening is formed, thereby forming a ring-shaped envelope space. It is possible to protect the optical cable by introducing the optical cable into / out of the ring-shaped envelope space from between arbitrary cable holding pieces and winding / holding the optical cable in the cable holding portion.

Further, since the mounting means provided on the shaft center can be mounted on the mounted member with one mounting screw, in the case of the mounted member, for example, an optical circuit board, it has a great influence on the layout design of the mounted components and wiring patterns. Will not be given.

[0014]

As described above in detail, according to the present invention,
It is a very useful effect that it can be applied to optical circuit boards etc. and facilitates wiring pattern design as it can be attached to a member to be attached at one place while holding and protecting the extra length of the cable as a loop Exert.
