[Industrial application field]

The present invention relates to a cable holder.

In recent years, information processing has become faster and faster, and in addition to differences in signal current levels, the influence of induction due to higher frequencies has become a problem for the wiring cables that connect devices inside and between devices. A fixing method that applies shielding processing is an issue.

[Conventional technology]

Figure 3(a) shows the housing wiring of a conventional example device, and Figure 3(b)
shows an enlarged view of the wiring fixing part.

As shown in FIG. 3(a), the conventional internal wiring of the device includes cables 9 for connection wiring in the vertical direction on the left and right sides of the device housing 8.
is accommodated, branched horizontally at a predetermined position, and wired to each connection terminal of the mounted shelf 7.

The cables 9 housed in the side surface of the device casing 8 are fixed vertically at appropriate intervals.

This fixation is accomplished by attaching the cable 9 with a nylon band 6 to a cable holder 56 that protrudes from the frame of the device housing 9 by fixing one end with a screw or the like.
is tied up and immobilized.

However, the accommodation side part has an elongated rectangular cross-section, and the cables 9 are grouped in advance into multiple groups according to signal type and characteristics at the design stage, and each cable is routed to the end without being bundled in the same way. Each side is held in a cable holder 56.

[Problem to be solved by the invention]

However, ■ the amount of noise induced in the cable 9 and the
The degree of influence due to mutual interference within a bundle or between other bundles may be difficult to analyze at the design stage, and the influence will not be known until after the equipment is put into operation, or whether it is bundled separately depending on the signal type, characteristics, etc.

■ If countermeasures are required due to these effects, untie the bundle of cables 9 already tied to each cable holder 56 by cutting the band 6, and change the wiring route to a position away from the item that will affect the cables. or divide the bundle into smaller pieces, separate them, etc., and then re-tether them.

(2) In particular, when wiring near the terminals of connectors of input/output circuits that require shielding due to their characteristics, it is necessary to wrap shielding tape or the like to suppress interference with other bundles of cables 9.

There are other problems.

SUMMARY OF THE INVENTION In view of these problems, it is an object of the present invention to provide a cable holder that allows a cable bundle to be fixed easily and repeatedly, and that can also be electromagnetically shielded if necessary.

[Means to solve the problem]

As shown in FIG. 1, the above objects are as follows: (1) A flexible half-tube body 1 with engaging claws 16 protruding from a split edge 15, and a half-tube body with a cable 9 housed inside. 1 comprises a plate-shaped fixing member 2, which has fixing holes 26 arranged in parallel at a predetermined interval, into which the engaging claws 16 are inserted and removably engaged and fixed, and which is protruded and fixed to the device structure. This is achieved by the cable holder 5 of the invention.

[2] Further, in the above-mentioned aspect of the present invention, the integral half-tube body 11, in which two half-tube bodies l are rotatably connected by a split edge 15, is removably engaged with and fixed to the fixing member 2. It can also be accommodated by a cable holder 5.

[3] It is also applicable to the cable holder 55 of the present invention, in which the split edge 15 at one end of the two halves of the cylinder 11 is rotatably connected to the tip of the fixing member 2.

[4] Also, the cable holder 5.55 of the present invention, in which both the half-cylindrical bodies 1 and 11 and the fixing member 2 are made of an electrostatic shielding or magnetic shielding metal material, can also be used.

[5] Further, in the present invention, the ferrite core 4 formed in a cylindrical shape through which the cable 9 is passed is held in the cable storage section 3 surrounded by the half-split cylinders 1 and 11 fixed to the fixing member 2. The cable holder 5, 55 may also be used.

[For production]

That is, since the half-tube l has flexibility, it can be properly fixed to the fixing member 2 by changing its cross section from a semicircle to a semi-ellipse depending on the amount of cables 9 accommodated inside. Cable 9 can be held.

This fixing is extremely simple because the engaging claws 16 protruding from the split edges 15 of the half-tube body 1 can be inserted into the fixing holes 26 of the fixing member 2 to engage and fix them.

Since the fixing holes 26 are formed at predetermined intervals in the fixing member 2, the half-cylindrical body 1 can be deformed and a plurality of half-cylindrical bodies 1 can be arranged and fixed in a predetermined position.

In addition, the wiring of the device casing 8 includes multiple cables 9 for each signal type.
Since it becomes a bundle of , the work can be made more efficient by holding it in a semi-cylindrical half-tube 1 in the shape of a semi-cylindrical shell or by using a half-tube 11 made by connecting two pieces.

Furthermore, the two halves of the cylindrical body 11 connected to each other are attached to the fixing member 2.
The cable holder 55 rotatably connected to the tip of the cable holder 55 can fix the half-tube 11 in a substantially circular shape, and can hold a large bundle of cables 9 accordingly.

Furthermore, as a measure against EMI (electromagnetic interference) caused by proximity between wires and between wires and terminals, it is effective to provide electromagnetic shielding at a predetermined cable holder portion.

In this electromagnetic shield, if the half cylinders l, 11 and the fixing member 2 are made of a metal material as a shielding material, the held cable 9
is surrounded by the half-cylindrical body 1.11 and the fixing member 2, so that a shielding effect can be obtained.

Moreover, sufficient effects can be obtained by gripping and fixing the cylindrical ferrite core 4 for EMI countermeasures through which the cable 9 is passed between the half-split cylinders 1 and 11 and the fixing member 2.

In this way, it is possible to provide a cable holder that allows the cable bundle to be fixed easily and repeatedly, and that can also be electromagnetically shielded if necessary.

〔Example〕

The present invention will be specifically described below with reference to embodiments shown in the drawings. The same reference numerals refer to the same objects throughout the design. Figure 1 (
a-C) show various cable holders according to embodiments of the present invention, FIG. 2(d) shows an enlarged view of the fixing part, FIG. 2(e-f) shows the same ferrite core, and FIG. The case wiring of the example, and the same shelf wiring are shown in the same figure (b).

This embodiment was implemented not only for overhead wiring accommodated on both sides of the device housing 8, but also for shelf wiring to a shelf branched from the overhead wiring.

The state in which this device is implemented is as shown in FIGS. 2(a) and 2(b).

The form of the cable holder is as shown in FIG. 1(a-f).

In this embodiment, the half cylinders 1 and 11 are molded from nylon, and the half cylinder 1 has a flexible thin semi-cylindrical shape as shown in FIG. 1(a). As shown in FIG. 1(d), engaging claws 16 are provided on the split edges 15 on both sides.

Further, the half-tube body 11 is formed by integrally molding two of the half-tube bodies 1 by joining them thinly and rotatably with a split edge 15.

The fixing member 2 is a rectangular iron plate, with thin rectangular fixing holes 26 arranged in parallel at regular intervals, and one end bent at a right angle with screw holes 27 drilled therein, so that it can be attached to the frame of the device housing 8 or the shelf 7. is fixed to.

In order to fix these half-cylindrical bodies 1, 11 to the fixing member 2, as shown in FIG. Nail 16,
When inserted into the fixing hole 26 of the fixing member 2 and pushed in, the engaging claw 16 is compressed and deformed by the width of the slit and penetrates, and the overhanging part expands and engages on the back side, and it does not come out as it is, but acts as a stopper. The cable holder 5 is configured by being fixed in place.

To take it out, the tip of the engaging claw 16 is strongly pinched with a fingertip and pushed in while being compressed by the width of the slit, so that the protruding part is contracted and disengaged, allowing it to come out from the fixing hole 26 and be taken out.

Further, the cable holder 55 has a split edge 15 at one end of the half-split cylinder 11 rotatably attached to the tip of the fixing member 2 in which the fixing holes 26 are arranged side by side.

For this attachment, a thin edge I7 is integrally provided on the split edge 15 and protrudes, and this thin edge 17 is fixed to the tip of the fixing member 2 with a screw, and since the nylon is thin, it is bendable and rotatable.

In addition, the engaging claw 16 protruding from the other end and the joining edge is inserted into the fixing hole 26 and engaged and fixed, and the other end is inserted into the two semicircular cylinder holders or the most advanced fixing hole 26. By fixing only the engaging claws 16, a substantially circular holder is formed.

Of course, since the fixing holes 26 are arranged side by side in the fixing member 2 of the cable holder 55, the half-split cylinders 1 and 11 can also be used in conjunction with the cable holder 2 described above.

Furthermore, in the holding part where EMI countermeasures are required, the
As shown in f), the protrusion 18 provided on the inner surface of the half-split cylinders 1 and 11 is fitted into the recess 41 provided at a predetermined position on the outer shape of the cylindrical ferrite core 4 through which the cable 9 is passed. They are then gripped and fixed.

This ferrite core 4 is available in a plurality of types having different shielding properties depending on the material, and can be selected and used as desired. still,
It is easier to use the ferrite core 4 if it is formed into a divided cylinder rather than an integral cylinder.

Furthermore, the half cylinders 1 and 11 may be formed of thin iron plates, which are not shown in the drawings, or may be formed in other embodiments, and a certain degree of shielding property can also be obtained.

In this case, the rotatable joint of the split edge 15 uses a hinge mechanism.

Of course, it is also possible to hold the ferrite core 4 in the same way.

The above embodiment shows an example, and the shapes and materials of each part are not limited to those described above.

For example, the engaging claw 16 is shaped like a sphere with a neck, and the fixing hole 26 of the fixing member 2 is a circular hole for fitting.Also, one engaging claw 16 is provided in the middle of the split edge 15, but multiple engaging claws 16 are provided in the middle of the split edge 15. There is no problem even if they are provided, and in that case, the fixing holes 26 may also be arranged in a plurality of rows.
