Abstract

PURPOSE:To obtain such a cable holder that a core wire does not have an excessive bend even if a device box moves while it is in the wired condition by installing the cable holder which has an axis-like projected part or a circular hole-shaped recessed part on its one end rotatably at a cable leading out position of the device box, with the projected or recessed part of the holder being set in the cable leading out position of the device box. CONSTITUTION:A cable 9 is held by a holder 1 at the rear end of a board of a device box 8. The holder 1 is a polyethylene molding. It has, on the front surface of a disk part 1, a cable holding device which holds the cable 9 tightly. The cable holding device is constituted of a band 12 and a band 13 with a fastener which are so installed as to face each other. As for an axis-like projected part, an axis part with a neck 14 is installed in the center of the rear surface of the disk part 11. The axis part with a neck 14 of the holder 1 is pushed into a fixation hole 2 which is made on the board of the device box 8 and the neck part is caught on the rear surface of the board of the device box 8 so that the holder may not slip out of the hole. Thus, the holder is fixed on the board of the device box 8 rotatably since the neck part of the holder is loosely fit in the hole of the board of the device box 8.

[Industrial application field]

TECHNICAL FIELD The present invention relates to a cable holder for use in a cable pull-out portion of a tabletop device or a small device.

Electronic devices are always connected to the outside of the device by cables, and the drawer portion requires a structure that matches the installation mode of the device.

[Conventional technology]

FIG. 2 shows a conventional cable holder.

Small electronic devices can be installed in various ways, such as table-top, wall-mounted, or floor-standing types, and it is desirable that they be small, lightweight, and easy to handle. An example that is simple enough to be easily implemented is the structure shown in FIG.

Generally, the cable 9 is connected by a connector, and the connector 91 at the tip of the cable 9 is fitted and connected to the connector 81 provided at a predetermined position inside the device casing 8, and the portion of the cable 9 that is pulled out from the device casing 8 The second
Figure (a) shows a fixing metal fitting 7 made by bending a strip into a U-shape at the center and then bending both ends outward.A cable 9 is housed in the U-shaped part, and both ends are screwed to the board of the device casing 8. and press down to secure it.

In Fig. 2(b), a U-shaped support fitting 6 is fixed to the board of the device housing 8, and a cable 9 is placed on this support fitting 6 and secured together with a nylon band 6I. let

As mentioned above, both have extremely simple structures.

[Invention or problem to be solved]

However, (1) Since it is a small device, it can be easily moved, so if it is a tabletop type or a stationary device, it may be moved around.

■ By moving the device housing 8 with the wiring still in place, the cable 9 is pulled and forcibly bent outside from the position where the fixing fittings 7 and the supporting fittings 6 are held, eventually causing a break in the core wire. I'm afraid.

There are some problems.

SUMMARY OF THE INVENTION In view of these problems, it is an object of the present invention to provide a cable holder that does not cause excessive bending of the core wires even if the device housing is moved while the wires are in the wired state.

[Means to solve the problem]

The above object, as shown in FIG. 1, includes: [1] a holder 1 equipped with a cable holding means for holding the cable 9 in a tight manner and having a shaft-shaped convex part or a circular hole-shaped concave part at one end; This is achieved by the cable holder 3 of the present invention, which is provided at a position where the cable 9 of the body 8 is led out, and is configured to fit into a convex portion or a concave portion of the holder 1 to rotatably attach the holder 1. .

[2] Also, a rail-shaped guide member 2 with a predetermined route length fixed to the holder and the cable introduction part of the device housing 8.
2 and a slider 23 which is slidably engaged with the guide member 22 and which rotatably attaches the holder 1 to the movable cable holder 4 of the present invention.

[For production]

That is, as the holder 1 holding the cable 9 rotates in the direction of pulling or bending the cable 9, no unreasonable bending force is generated in the holding part, but in the device casing 8 beyond it. For bending, if a distance and extra length are provided before the fixed part at the end of the cable 9, the bending and tensile forces can be easily and reliably absorbed.

Further, even if the device housing 8 is moved relatively largely, the tensile force and compressive force of the cable 9 can be alleviated by moving the holder 1 by means of the slider 23 sliding on the guide member 22. For example, if it is pulled, it will move a predetermined amount in that direction and the pulling force will be absorbed.

The route and length of the guide member 22 may be set so as to be movable in a direction that effectively affects the movement of the device casing 8. This can be easily realized using a known mechanism such as a floater 23 that engages with the slit and slides along its entire length along the slit without coming off.

(Thus, it becomes possible to provide a cable holder that does not cause excessive bending of the core wire even if the device casing is moved while the cable is in a wired state.

〔Example〕

The present invention will be specifically described below with reference to embodiments shown in the drawings. The same reference numerals indicate the same objects throughout the figures. Figure 1 (
Figure a) shows a holder according to an embodiment of the present invention, Figure (b) shows the same cable holder, and Figure (C) shows the same movable cable holder.

This example was applied to a tabletop electronic device measuring 50 x 25 x 6 cm in height, and because it is not fixed, it may be moved each time an operator changes, or the tabletop arrangement may be changed due to the addition or reduction of other devices, etc. There are problems with the structure shown in the conventional example described above, and improvements are required.

As shown in FIG. 1(b), the cable 9 is drawn out from the rear of the device housing 8, and a connector 91 at the tip of the cable 9 is connected to the connector 81 inside.

This cable 9 is held by the holder 1 at the rear edge of the substrate of the device housing 8.

As shown in Fig. 1(a), the holder 1 is a polyethylene molded product, and has a disc portion 1 of 15φ x 4mm.
A band 12 and a band 13 with fasteners are protruded from the front surface of the holder as cable holding means for holding the cable 9 in a tight manner, and a necked shaft portion 14 is provided at the center of the back surface as a shaft-shaped convex portion. is installed vertically.

As shown in FIG. 1(b), the cable holder 3 to which the holder 1 is rotatably attached has a fixing hole 82 drilled in the board of the device housing 8, and the necked shaft of the holder 1 Part 14
By inserting and pushing in, the neck part gets caught on the back side and loosely fits into the stopper, and is fixed rotatably.

After connecting the connector to the holder 1 installed in this way, the cable 9 is curved vertically as much as possible to provide extra length.
Place it and secure it tightly with bands 12 and 13.

Thus, even if the cable 9 is pulled or bent on the outside,
The holder 1 immediately rotates in that direction, eliminating the generation of unreasonable bending force, and the tensile force is stopped at the tensioned portion, without affecting the inside.

Furthermore, if the cable 9 has only a small amount of extra length on the outside, if the device housing 8 is moved on a tabletop, tensile or compressive force will be generated directly by the above-mentioned rotation, causing strain or difference in movement. In order to alleviate the support force, the cable holder 4 and the holder l are also allowed to rotate and move in the direction of external force.

As shown in FIG. 1(C), this movable cable holder 4 has a rotating and moving means composed of a rail-shaped guide member 22 and a slider 23 that is slidably engaged with the guide member 22. The guide member 22 is a rectangular cylindrical rail with a rectangular cross section that has a slit 21 on one side with both ends closed, and the floater 23 is a disk that moves freely within the cylinder and has a through hole 24 in the center.

If the necked shaft part 14 of the holder 1 is inserted from the outside through the slit 21 and into the through hole 24 of the swinger 23 and pushed in, the neck part will be caught on the back side to prevent it from being pulled out, and the loose fitting will fix it so that it can rotate freely. At the same time, it is attached movably along the slit 21.

Here, in order to most effectively reduce the movement of the device casing 8 or the force applied to the cable 9, the guide member 22 may be fixed to the device casing 8, for example by aligning the route of the slit 21 with the direction of movement. This is important, and in this embodiment, a guide member 22 with a length of 15 cm is fixed with screws along the rear edge of the substrate of the device housing 8, with emphasis on the influence of movement in the left and right direction.

Therefore, even if the device casing 8 is moved left and right in use, the cable 9 is not affected in any way.

The above embodiments are merely examples, and the shapes, dimensions, and materials of each part are not limited to those described above.

The holder 1 may have a structure in which the bands 12 and 13 are not integrated and other standard products are used.Also, for rotational mounting, the mechanism is also attached to the holder 1 with a convex necked shaft. Instead of 14, a structure may be provided in which a concave portion is provided for fixing a shaft with a stopper of a convex portion vertically disposed on the substrate of the device casing 8 to the disk portion 1].

Further, the movable means of the cable holder 4 may be composed of a guide member 22 and an inner floater 23, or may be a guide member that covers the floater externally.Furthermore, the floater may be omitted and the floater portion may be integrated into the holder l. There is no problem in setting it up.

Furthermore, the guide member 22 may be fixed at any necessary location on the side or top surface of the inside of the device housing 8, and its route may be a straight, horizontal curve or a three-dimensional curve.

In addition, if the holder 1 is used in common for the cable holder 3 that only rotates and the cable holder 4 that can be moved,
There is no problem with holders having separate shapes.

〔Effect of the invention〕

As described above, with the cable holder of the present invention, even if the device housing is moved while the wiring is still in place, the core wires will not be forced to bend, and there will be no disconnection.
There is no need to tighten screws, and workability is improved, which has great practical effects.
