Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable housing portion for housing a substrate in a housing.

[0002]

2. Description of the Related Art FIG. 5 is a perspective view showing a conventional cable storage state. In FIG. 5, the board 4 is housed in a case 1 in a shelf shape, the cable 5 is joined to the connector 6 on the board 4, and the board 4 is electrically connected. Note that the cable 5 has a length including an extra length portion in consideration of reconnection when the cable 5 is disconnected. In particular, in the case of an optical cable, a curvature with a diameter of 30 mm or more is required, and the cable 5 has an extra length portion in consideration of damage to the cable 5 due to sudden bending. The housing 1 has a cover 2 that can be opened and closed. The extra length portions of the plurality of cables 5 connected to the substrate 4 are bundled together, inserted into the cable support 3 attached to the inner wall of the cover 2 and fixed, and then the cover 2 is closed to form a housing. It has a structure that can be stored in 1. Although FIG. 5 shows an example in which the cable 5 connects the substrates 4 to each other, the cable 5 may connect the substrate 4 to the outside in some cases. Even in the case described above, in order to protect the cable 5, the extra length portion of the cable 5 is housed in the housing 1.

[0003]

In the conventional cable storage section, a plurality of cables contained in one housing are bundled together in a cable support fixed to the inner wall of the cover, with the extra length portion being bundled into the housing. It was stored. Therefore, when attaching or detaching one cable, remove all the cables bundled together from the cable support, attach and detach the corresponding cables, and then reassemble the cable bundle to reassemble the cable support. The work of inserting the cable into the cable was necessary, and extra time was spent in attaching and detaching the cable. Further, there is a problem that the cable is damaged due to complicated work of attaching and detaching the cable. Further, when stress is applied to the cable when the cover is closed, the stress continues to be applied even after the cover is closed, which deteriorates the characteristics of the cable and lowers the durability.
An object of the present invention is to facilitate the work of attaching and detaching the cable and prevent the cable from being damaged and deteriorated.

[0004]

In order to solve the above-mentioned problems, in the cable housing portion of the present invention, a cable is
The cable is attached to the cable support for each book, and the cable is movably attached so that the stress applied to the cable can be released.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. Elements common to the drawings are denoted by the same reference numerals. FIG. 1 is a perspective view showing a cable storage state of a first embodiment according to the present invention, and FIG.
It is a detailed view of the main part in. In FIG. 1, the board 4 is mounted in a shelf shape. The board 4 has a connector 7, and the board 4 is electrically connected by joining the connector 7 and the cable 5. The housing 1 has a cover 2 that can be opened and closed, and the inside of the cover 2 is a space for accommodating the extra length cable 5. In the present embodiment,
Although an example in which eight boards 4 are mounted and three cables 5 are connected is shown, the number of boards 4 and cables 5 is not limited to this.

The cable support 31 has a tubular shape, and an opening is provided in the tube so that the cable 5 can be removed. When the cover 2 is closed, the opening faces the substrate 4. It is mounted on the inner wall of the cover 2. Also,
The cable support 31 is formed of a material having low friction such as polyester resin and nylon, and the cable 5 inserted into the tube of the cable support 31 can be moved within the tube. In addition, the cable 5 is 1
As each book is attached to the cable support 31,
At the time of work such as installation and removal of the cable 5, only the corresponding cable 5 needs to be installed and removed.
Therefore, when storing multiple cables by bundling them, and when attaching or detaching cables, remove all cables from the cable support once, attach and detach the corresponding cables, and then reassemble the cable bundle. As compared with the conventional method in which the cable 5 is inserted into the cable support, the work is facilitated and the occurrence of breakage of the cable 5 due to the work can be reduced.

In the present embodiment, one cable is held by two cable supports 31 above and below the inner wall of the cover 2, but the cable support 31 is attached only above the inner wall of the cover 2. It is also possible to hold. In addition, FIG. 1 shows an example in which the cable supports 31 are arranged in parallel on a straight line, but in this case, as shown in FIG.
A sharp bend is apt to occur in the cable 5 like the A part.
Therefore, the cable support 3 is placed on the track of the cable 5.
It is more effective in terms of protection of the cable 5 if the cable supports 31 are arranged in a staircase so as not to hit 1.

Next, the operation of the cable 5 when the cover 2 is opened and closed will be described. The extra length portion of the cable 5 is bent with an appropriate curvature and is attached to the cable support 31 one by one. When the cover 2 is closed, the cable 5 is bent and stress is applied according to the movement of the cover 2. At this time, the cable 5 moves in the tube of the cable support 31 in the direction of releasing the stress, so that the stress applied to the cable 5 can be reduced. In addition, with the cover 2 closed,
The cover 2 is made thick so that the storage space for the cable 5 is large so that the curvature of the cable 5 does not become small near the opening / closing axis of the cover 2. The large storage space for the cable 5 prevents the cables 5 from pressing each other during the storage of the cable 5, so that the stress applied during the storage of the cable 5 can be reduced. Further, when the cover 2 is opened, the cable 5 is pulled in the direction of opening the cover 2, but by moving inside the tube of the cable support 31, the stress due to the pull can be released. Therefore, it is possible to prevent the characteristics of the cable 5 from being deteriorated and the durability thereof from being lowered due to the stress.

FIG. 3 is a perspective view showing a state of a cable stored in a second embodiment according to the present invention, and FIG. 4 is a detailed view of a main part in FIG. The second embodiment is similar to the cable support 31 of the first embodiment except that the cable 5
Does not move within the tube of the cable support 31, but the cable support 31 moves along an axis provided inside the cover 2. In FIG. 3, the shaft 6 is mounted inside the cover 2. The cable support 32 includes a cable fixing portion a and a shaft support portion b. The cable fixing part a is
It has a tubular shape, and an opening is provided in the tube so that the cable 5 can be attached and detached. Further, the cable fixing portion a is a tube having a diameter adapted to the thickness of the bundle of the cables 5 in the extra length portion so that the cable 5 does not move in the cable fixing portion a. The shaft support portion b is attached to the shaft 6 and is movable along the shaft 6. In the present embodiment, the rod-shaped shaft 6 is penetrated by the ring-shaped shaft supporting portion b and is movable. However, if the cable support 32 is movable, the shaft 6 and The shape of the shaft support portion b is not limited to this.

Next, the operation of the cable support 32 when the cover 2 is opened and closed will be described. Extra length cable 5
Are bent with an appropriate curvature and are attached to the cable support 32 one by one. When the cover 2 is closed, the cable 5 is bent and stress is applied according to the movement of the cover 2. At this time, the cable 5 tries to move in the direction of releasing the stress, but the cable 5 is moved within the cable fixing portion a.
Does not move, so that the stress related to the cable can be released by moving the shaft support portion b along the shaft 6. As in the first embodiment, since the cover 2 is thickened to make the space for storing the cable 5 large, the curvature of the cable 5 does not become small near the opening / closing axis of the cover 2 and the cable 5 is stored. Since the cables 5 do not press each other inside, the stress applied during the storage of the cables 5 can be reduced. Further, when the cover 2 is opened, the cable 5 is pulled in the direction of opening the cover 2, but the stress due to the tension can be released by moving the shaft support portion b along the shaft 6. Therefore, it is possible to prevent the characteristics of the cable 5 from being deteriorated and the durability thereof from being lowered due to the stress. Furthermore, since the curvature of the cable 5 in the extra length portion does not change when the stress is released, it is necessary to give the cable an appropriate curvature, especially in the case of an optical cable. The effect of preventing the deterioration of the characteristics and the durability of the cable 5 is higher than that of the part.

The mounting direction and mounting position of the shaft 6 are preferably set in accordance with the opening / closing direction of the cover 2 so that the cable support 32 slides effectively when the cover 2 is opened / closed. Therefore, in the present embodiment, since the opening / closing axis of the cover 2 is vertical, the axis 6 is attached in the horizontal direction. However, when the opening / closing axis of the cover 2 is horizontal, the axis 6 is attached in the vertical direction. The mounting direction of the shaft 6 may be determined according to the opening / closing direction of the cover 2. Further, the shafts 6 are provided one each at two places above and below the inner wall of the cover 2, but when the shaft 6 is attached only above the inner wall of the cover 2,
It is possible to obtain the same operation as when the shaft 6 is attached to the upper and lower portions, and the attaching position and number of the shaft 6 are not limited to the example of the present embodiment. Further, when the axis of opening and closing the cover 2 is horizontal, the number of the shafts 6 is increased in accordance with the increase in the number of cables, and the adjacent shafts 6 and 6 and the inner wall of the cover 2 and the shaft 6 are adjacent to each other. The mounting position and the number of the shafts 6 may be determined so that the space is wide and the cable support 32 slides effectively.

[0012]

Since the present invention is configured as described above, the following effects can be obtained. In the cable storage portion, since each cable is attached to the cable support, the work for attaching and detaching the cables can be facilitated. Further, since the cable is movable, the stress applied to the cable can be released, and the damage and deterioration of the cable can be prevented. Further, since the cable is movable while maintaining a constant curvature, the curvature of the cable does not change due to stress, and a high effect can be obtained in preventing damage and deterioration of the cable.
