BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable holder for use in a frame housing. BACKGROUND OF THE INVENTION Cables of multiple electrical wires are used to connect electronic devices to each other and to the outside. In recent years, especially with the practical use of optical communications, optical fiber cables have also come to be used together in the same equipment.

[0002] Compared to electric wires, optical fibers have advantages such as being extremely thin, having high tensile strength, transmitting a much larger amount of information, having little transmission loss, and having almost no mutual induction with the outside. Although it has developed rapidly, the disadvantage is that it is easily bent because it is a thin wire, and if it is bent to a smaller diameter than the minimum allowable bending diameter, the transmission loss will suddenly increase or the wire will break, so be very careful when handling it. Electrical wires can be easily connected by soldering or screwing, but optical fibers are connected using glass, and in order to reduce connection loss, it is necessary to minimize misalignment as they are thin. Furthermore, the end surfaces must be welded or brought into close contact with each other without any gaps, which is extremely difficult compared to connecting electric wires.

[0003] Therefore, when introducing an optical fiber cable into an electronic device, it is necessary to separate it from other electric cables and to handle it, wire it, and hold it with care to prevent bending.

[0004] Furthermore, when connecting a connector to a cable with an external device, special tools are used to attach the connector to the end of the optical fiber, so it cannot be done near the connection.
Since we are using optical fiber cables that have already had their connectors installed in a separate location with special tools, it is difficult to wire the cables to the optimum length without excess length, resulting in excess length. A surplus length processing structure is required to absorb the excess length by winding it inside the device.

[0005]

[Prior Art] Fig. 4 shows an example of a conventional optical fiber cable processing structure, Fig. 5 shows the optical fiber cable arrangement section, and Fig. 6
Figure 2 shows the extra length absorption section of the same optical fiber cable.

A conventional example of a structure for processing optical fiber cables inside a housing of an electronic device is as shown in FIG. Optical fiber cable to be connected 9
are introduced vertically in the vertical direction and are connected to each of the circuit units 81A, 81B, .
5 and is guided vertically and horizontally depending on the orientation.

[0007] The cable 9 that was first introduced in the vertical direction is held by the wire straightening section 55, and then is connected to each circuit unit 81A.
, 81B, .

As shown in FIG. 5, the wire alignment section 55 is screwed to a plurality of fixing fittings 85 that protrude rearward from the rear upper edge of each circuit unit 81A, 81B, . A straightening curved iron 86 is installed horizontally on the straightening curved iron 86, and holders 15 are fixed at predetermined intervals at predetermined positions on the straightening curved iron 86 to hold the cable 9 in the vertical direction.

As shown in FIG. 6, the extra length accommodating portion 56 has the holder 15 fixed near one end and the other end, and an elongated winding fitting 87 with the other end serving as a fixed portion.
A plurality of cables are vertically screwed and fixed at predetermined intervals to the rear lower edge of the cables B, .

The holder 15 is made of a synthetic resin integrally molded with a C-shaped holder portion 25 for accommodating and holding the cable 9, and an arrow-shaped fixing portion 35 protruding outward from the center of the holder portion 25. The fixing portion 35 is inserted into a hole provided at a fixing position, and the arrow-shaped portion is elastically widened on the opposite surface and fixed.

[0011]

[Problem to be solved by the invention] However, ■
This cable holder consists of a wire straightening section 55 and an extra length accommodating section 56, and requires a lot of man-hours for machining since it has a large number of component parts.In addition, the number of man-hours for assembling is also large because each metal fitting and curved iron are screwed together. (2) The holder 15 of the wire straightening section 55 and the winding fitting 87 of the extra length accommodating section 56 are required as a set at a location where the cable 9 needs to be processed. ■ The maximum number of extra length accommodation sections 56 is determined from the width dimension of the cable duct section 7 and the minimum bending radius of the cable 9.
The mounting position is automatically determined, and the fixing position of the holder 15 in the line straightening section 55 is also determined correspondingly. ■ On the other hand, although the circuit functions of each circuit unit 81A, 81B, etc. differ depending on the type and combination of circuit packages plug-in mounted inside, they are structurally common, so when using the optical fiber cable 9, The maximum number of holders 15 and winding fittings 87 are arranged and assembled at the time of assembly, which results in unused parts resulting in waste and obstructing the wiring of electric wires and cables (not shown). There were problems such as.

In view of these problems, the present invention provides a cable straightening section and an extra length accommodating section in accordance with an arbitrary connection position, and also allows the cable processing member to be left attached and not in use. To provide a cable holder that eliminates waste and interference with other wiring.

EXAMPLES The present invention will be specifically explained below with reference to examples shown in the drawings. The same reference numerals indicate the same objects throughout the figures. FIG. 2 shows one embodiment of the invention, and FIG. 3 shows another embodiment of the invention.

An embodiment of the present invention is as shown in FIG.
Optical fiber cables 9 are vertically routed in the cable duct section 7 on the rear surface of the rack housing 8, and are connected to circuit units 81A, 81B, etc. mounted on the rack housing 8 and to external devices using connectors. However, in this cable holder, two rod members 4 are fixed at both ends with screws to the tips of curved iron protruding rearward from both side plates of each circuit unit 81A, 81B,..., and connected to the rear cable duct section 7. Two rod members 4 are installed in parallel, and this rod member 4 is a molded iron plate having a U-shaped square cross section.

The holder 11A fixed to the bar member 4 has an angular C-shaped holder portion 2 measuring 12 mm x 15 mm wide x 12 mm in width, and has U-shaped grip portions 3A on the upper, lower, and rear three outer sides. It is a polyamide resin product in which parts 3B and 3C are integrally molded, and the gripping parts 3A, 3B, and 3C elastically grip the rod member 4 and fix it in that position.
It can be easily removed by pulling it, and there are three types of grip parts 3A so that the installation direction can be changed.
, 3B, 3C, and there is a grip part 3 in the upper and lower wiring direction.
A or 3C, if the extra length winding surface is parallel to the plane formed by the two rod members 4, use the grip part 3B, or if it is perpendicular to the same plane, use the grip part 3C, and the same holder 11A
to meet all uses.

Another embodiment of the present invention is as shown in FIG. 3, and differs from the above embodiment in that the rod member 41 is an iron tube with a circular cross section.
, 3E are changed to round shapes, and their positions are shifted and integrally provided on one surface of the outside of the holder part 2. In this case, the cables 9 are wired in the vertical direction and in the remaining direction parallel to the surface. They are the same except that they are used for long winding surfaces.

Although the bar member 41 has a circular cross section, the holder 1
The elastic force of the gripping parts 3D and 3E of 1B can sufficiently fix it in a predetermined direction. In any of the above embodiments,
Only the necessary number of holders 11A and 11B should be installed in the specified positions, and unused ones should not be attached, and should be prepared by the wiring worker as consumable items like a tie to the holder used in the past. There is no problem of excess or deficiency.

The above embodiment shows one example, and the bar members 4 and 41 were made of iron plate molding, but other molded products made of other materials such as aluminum square bars or round bars may also be used. For example, a rod member bent in an L-shape may be installed instead of the L-shaped construction. Further, the position and orientation of the grip portion are not limited to those described above.

Although the cable 9 is an optical fiber cable, it may also be applied to an electric wire cable.
Although the present invention has been described as an example of wiring in the rack casing 8, it is obvious that the present invention can also be applied to the inside of the circuit units 81A, 81B and other wiring housing parts.
