Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable holder for holding a plurality of cables through openings in a wall such as a casing.

[0002]

2. Description of the Related Art In order to pull out a plurality of cables from a casing or the like, or to draw them into a casing or the like, one or more through holes for passing the cables are provided in a wall of the casing, and the periphery of the through holes is formed into the casing. A method is known in which an elastic packing is arranged to prevent dust and splashes from entering. This method has the advantage that the structure of the holding device is simple, but when passing the cable through the through hole, first remove accessories such as plugs from the tip of the cable, then pass the cable through the through hole, and then reconnect the plug and so on. It requires complicated work such as reattaching.

To solve this, for example, Japanese Patent Laid-Open No. 7-7
832 discloses at least two foam materials.
The two layers are juxtaposed, the cable is passed between the layers, and moderate pressure is applied to the layers and the cables passing between them so that the cable is cut into the surface of the foam material layer, and the layers are guided along the cable. A configuration has been proposed in which a cable is held by forming a recess.

[0004]

This structure has the advantage that the work efficiency can be improved without the need for the troublesome work such as attaching and detaching the plug or inserting the cable into the through hole as described above. However, for example, when the cable sandwiched in the foam material layer receives a force such as vibration or tension and moves to the left, right, front and back, the foam material layer deformed along the shape of the cable according to the movement of the cable. The cavities gradually expand to form a gap with the cable, and the cable cannot be held sufficiently. This naturally impairs the role of preventing dust and splashes from entering the casing.

Therefore, it is an object of the present invention to provide a cable holder which can hold a cable sufficiently without affecting the infiltration effect of dust and splashes and which has a high efficiency of attachment work. And

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. 1A to 1E show an example of a cable holder according to the present invention, where FIG. 1A is a front view, FIG. 1B is a sectional view taken along the line E-Y of FIG. A, and FIG. 2D is a cross-sectional view, and (D) and (E) are a top view and a side view of FIG.

A plurality of cables 1 can be passed through a wall 3 of the casing 2 in order to be able to guide a plurality of cables 1 into a casing 2 and to connect its ends to a connection in the casing 2. The opening 4 having various sizes is formed. The opening 4 preferably has a rectangular shape, but may have another shape such as a circular shape.

A cable holder 10 is attached so as to cover the opening 4 from the outside of the wall 3. Cable holder 1
0 includes a plurality of blocks 11, 12, 13, 14 which are attached to the wall 3 from the outside so as to cover the opening 4. The cable 1 has an opening 4 in each of the blocks 11, 12, 13, and 14.
It consists of an independent block body that can be separated in the transverse direction with respect to the direction passing through. In the example shown in FIG. 1, each of the blocks 11, 12, 13, and 14 is composed of a horizontally elongated block having a U-shaped cross section or a D-shaped cross-section having vertically spaced walls, and each of the blocks extends in the longitudinal direction ( Alternatively, the edges are arranged so as to be aligned with the surfaces (or edges) of the adjacent blocks. Each block is fixed by the fixing means 16 in this combined state. In the example shown in FIG. 1, the blocks 11 and 14 at both ends have substantially symmetrical shapes, and the central blocks 12 and 13 have substantially the same shape. As will be described later, the number of the central blocks 12 and 13 is two in the illustrated example, but the number is not limited to this and may be a desired number of blocks.

FIG. 2 is an exploded view of the cable holder 10 shown in FIG. 1, and an example of the configuration of each block will be described with reference to this.

Each of the blocks 11, 12, 13, and 14 has a cable 1 on the upper and lower walls on the mating surface side with the adjacent blocks.
Notch parts 11a, 12a, 13a, 14 for passing through
a, and hollow portions 11b, 12b, 13b, 14b that detachably accommodate the elastic packings 17, 18 so that the recesses described later are located at positions corresponding to the notches. The cutouts 11a, 12a, 13a, 14a are, for example, substantially semicircular, have a diameter at least larger than the diameter of the cable to be held, and are formed in plural along the longitudinal direction of the block. Notch parts 11a and 12
a, 12a and 13a, 13a and 14a respectively form a substantially circular shape when they are formed at the positions facing each other. On the other hand, the hollow portions 11b, 12b, 13b, and 14b are hollow cuboid grooves each having a substantially rectangular parallelepiped shape that is open on the mating surface side with an adjacent block.
It extends horizontally (longitudinal direction of the block). Elastic packings 17, 18 having a substantially rectangular parallelepiped shape are detachably fitted and mounted in the hollow portion. As the elastic packing, for example, a material having elasticity suitable for pressing and holding the cable with an appropriate pressure such as a rubber packing is preferable.

FIG. 2 shows two types of elastic packings. The packings 17 and 18 mounted between the blocks 11 and 12 and between the blocks 12 and 13 are the longitudinal directions of the blocks 11 and 12. The elastic packing 19 which is composed of a single laterally elongated substantially rectangular parallelepiped and which is arranged between the blocks 13 and 14 is a plurality of small block bodies which are individually detachable from the hollow portions 13b and 14b. It consists of a combination of.

Regarding the horizontally long packings 17 and 18, the cutout portions 11a, 12a,
The cables 1 are respectively provided at the positions corresponding to 13a and 14a.
Has substantially semi-circular recesses 17a and 18a for holding the cable, and the recess 17a and the recess 18a of the elastic packing attached to the adjacent block face each other to form a substantially circular recess, whereby the cable The cable 1 is tightened by covering the periphery of the cable 1 and the cable is held without a gap. Therefore, it is preferable that the recesses 17a and 18a have a diameter equal to or slightly smaller than the diameter of the cable to be held.
The depths of 7 and 18 are the hollow portions 11b to 13b of the block.
Is preferably slightly longer than the depth of. In the illustrated example, the recesses of a single packing have the same diameter,
The diameter of each recess may be different.

With respect to the packing 19 composed of a plurality of small blocks, a plurality of types of packing 19 having different recesses 19a are prepared, and the recess 19a having a diameter corresponding to the diameter of the cable to be held is prepared. The elastic packing having the above is selected and used by being detachably fitted into the hollow portion of the block. The recess 19a of the packing 19 has a diameter equal to or slightly smaller than the diameter of the cable to be held, as in the case of the packings 17 and 18, and the depth of the packing is slightly smaller than the depth of the hollow portions 13b and 14b. It is preferably long.

On the other hand, as a fixing means for fixing each block together with an adjacent block, for example, a pair of lengths are formed by penetrating through holes 11c to 14c formed in side walls of both ends of blocks 11 to 14, respectively. Screws 16 are attached. The head of the long screw 16 is larger than the diameter of the through hole 11c and is prevented from coming off due to this, and in order to individually tighten the adjacent blocks 11 to 14, the block 1
Between the nuts 2 and 13, between the blocks 13 and 14, and outside the block 14, respectively, the nuts 20, 2
1, 22 are screwed into the long screw 16 and tightened.

After fixing between the blocks in this way, bolts or screws are inserted into the fixing holes 11d to 14d formed in the skirt portion of the lower wall of the block and screwed to the wall 3 of the casing. Fix the block to the wall 3. In FIG. 1 (A), the fixing holes of the blocks are fixed by bolts. However, since the blocks are connected by the fixing means, it is not always necessary to fix the fixing holes for all the blocks.

FIG. 3 shows an example in which the number of blocks is changed, (A) uses four blocks, (B) uses three blocks, and (C) uses two blocks.

[0021]

As described above, according to the present invention,
The cable can be passed through the casing or the like by a simple operation, and the blocks can be combined in order to easily hold the cable in a dustproof state. In addition, by selecting the number of blocks, the optimum form can be selected according to the number of cables, and when the elastic packing is a combination of small blocks,
For cables of different sizes, a packing having a recess having a diameter suitable for each cable can be used to hold the cables with a suitable seal.
