Description

The present invention relates to a cable holder that can be attached to a wall such as a casing of an electric device without holding a cable in which a plurality of covered electric wires are bundled together, and in particular, elastically hold the cable so as not to damage it. Workability at the time of assembly is remarkably improved by forming multiple protrusions to prevent each elastic packing from moving laterally in the hollow part formed in each block in order to detachably store the elastic packing In addition, by inserting a nut to which the headed screw is screwed into one of the blocks so that it cannot rotate, it is extremely easy to insert and tighten the headed screw from the tightening part of the other block. Each block is tightened and fixed to improve the efficiency of assembly work, and the adhesion of each block is increased to maintain the cable holder. The IP rating is IP54 (IP is an abbreviation for International Protection. JIS 529, JISC 0920) is a protection rating indication of solid foreign substances, electrical equipment against water, cabinets, and “IP” is a protection characteristic. The symbol “5” is “dust-proof” (prevents dust from entering inside. Even if some dust enters, normal operation is not hindered), “4” “protects against splashes” ”(Not adversely affected by splashes of water from any direction), and when attaching the finished cable holder to the wall of the casing, etc., it can be applied to the wall from either the front or back side. The present invention relates to a cable holder that can be attached and has improved usability.

First, the conventional example will be described with reference to FIGS. 23 to 27. The cable holder 1 disclosed in Patent Document 1 is separated in a direction (crossing direction) perpendicular to the direction of passing a cable (not shown). A plurality of blocks 3 (3A, 3B, 3C) that can be attached together with the adjacent blocks 3A, 3B, 3C, respectively. An elastic packing 4 having a notch 3b for passing a cable (see FIG. 2) through the surface 3a and a substantially semicircular recess 3c for holding the cable at a position corresponding to the notch is detachable. A hollow portion 3d is formed, and is configured to hold the cable by covering the periphery of the cable with the concave portion 3c and the concave portion 4c of the elastic packing 4 attached to the adjacent block 3. The wall opening such as a casing (not shown) (see FIGS. 6 and 16 and 17) in which is mounted so as to cover the.

However, the hollow portion 3d is basically formed as a groove having a rectangular cross section, and its bottom surface 3e is flat and has no irregularities. Therefore, the elastic packing 4 accommodated therein has the inside of the hollow portion 3d, As shown in FIGS. 26 and 27, the robot can move freely as indicated by arrows A and B. As shown in FIG. 24, when the elastic packing 4 is accommodated in the hollow portion 3d without any gaps, the elastic packing 4 at both ends contacts the end surface 3f of the block 3 (3B). However, the elastic packing 4 moves appropriately during the housing operation of the elastic packing 4 so far, making it difficult to assemble, and the assembly work efficiency is improved. There was a disadvantage that it was not good.

Further, regarding the degree of adhesion after the tightening of each block 3 and the ease of tightening work, only the fool hole 3h is formed in the tightening portion 3g of each block 3, and the tightening of each block 3 is shown in FIG. As shown in Fig. 2, the long headed screw 5 is first inserted into the two hollow holes 3h of the block 3A, and after passing through the hollow hole 3h of the block 3B, the nut 6 is screwed into the headed screw 5 to screw the headed screw. 5 is screwed to the approximate center of the screw 5 and the protruding male screw portion 5a of the headed screw 5 is further inserted into the hole 3h of the block 3C, and the nut 8 is screwed into the screw portion 5a protruding from the hole. The blocks 3A and 3B are tightened with the nut 6, and then the blocks 3B and 3C are tightened with the nut 8 to complete the assembly operation.
In this case, in order to fasten the nut 6 for the block 3B, since the male screw portion 5a of the headed screw 5 protrudes long, it is difficult to use a socket-shaped wrench, and inevitably a single-open wrench is used. In addition, the head 5b of the headed screw 5 must also be added with a spanner to prevent co-rotation of the headed screw, so the work efficiency is low, and there are a total of four nuts 6, 8 Therefore, the nuts 6 and 8 need to be tightened by a total of four spanners, the work efficiency is not good, and the degree of adhesion between the blocks 3 cannot be expected.

Further, in the cable holder 1 of the conventional example, a packing for accommodating a rod-like packing (not shown) (see FIG. 8) for attaching the cable holder in close contact with a wall of a cassy (not shown). Since the groove 3i is not provided at all on the front surface 3m of each block 3, but is provided only on the back surface 3n and the mating surface 3a, the cable holder 1 is a method other than mounting with the back surface 3n on the wall side. However, even if necessary, it was impossible to attach the cable holder 1 in the reverse direction.

Packing groove sexual packing is accommodated is provided on both sides of the block, the surface against the wall and is characterized by being configured to be mounted from either side of the back surface.

Hereinafter, the present invention will be described based on embodiments shown in the drawings. 1 to 12, the cable holder 11 according to the present invention has a plurality of blocks 13 (13A, 13B, 13C) that can be separated in a direction orthogonal to the direction in which the cable 12 passes. The block is configured to be attached together with the adjacent block 13, a notch portion 13b for passing the cable 12 through a mating surface 13a with the adjacent block 13, and a position corresponding to the notch portion. And a hollow portion 13d that detachably accommodates an elastic packing 14 having a substantially semicircular concave portion 13c for holding the cable 12, and the concave portion of the elastic packing 14 attached to the block 13 adjacent to the concave portion 13c. 14c so as to cover the periphery of the cable 12 and hold the cable 12, and cover the opening 19a of the wall 19 such as the casing 18. And a convex portion 13p formed by a plurality of arcs so that the elastic packing 14 cannot move laterally is provided on the bottom surface 13e of the hollow portion 13d that detachably accommodates the elastic packing 14. It is a thing.
The interval between the plurality of convex portions 13p, that is, the pitch is made to coincide with the pitch of the notched portions 13b and the concave portions 13c.
That is, when the number of cables 12 is n, the number of convex portions 13p is n-1. Since the elastic packings 14 at both ends cannot move in contact with the end face 13f of the hollow portion 13d of the block 13, the number of the convex portions 13p is sufficient.
The shape of the convex portion 13p is not limited to the shape formed by the circular arc as shown in the figure, and any shape can be used as long as it can prevent the lateral movement of the elastic packing 14.
The outer side 14a of the elastic packing 14 is formed in an arc shape with the same radius of curvature, but the recess 14b for elastically holding the cable 12 has a curvature corresponding to the diameter of the cable. A radius is defined. That is, as shown in FIG. 13, the radius of curvature is set so that the diameter of the hole 14 c formed when the pair of elastic packings 14 are opposed to each other is slightly smaller than the diameter of the cable 12. Is formed.

The block 13 is integrally formed of a synthetic resin such as polycarbonate, nylon, or polyacetal. For example, in the case of the three pieces shown in FIGS. 1 to 15, the blocks 13A and 13C on both sides and the both sides in the horizontal direction. It is composed of three central blocks 13B formed symmetrically, and in the case of the two pieces shown in FIGS. 20 and 21, it is composed of two blocks 13A and 13C on both sides.

On both sides of the convex portion 13p, a substantially semicircular shape that is the same as the shape of the outer side 14a of the elastic packing 14, that is, an arc-shaped lateral movement preventing concave portion 13q is formed, and the hollow portion 13d has a plurality of convex portions 13p and the substantially semicircular shape. It is formed in a wave shape continuous with a circular lateral movement preventing recess 13q.
By making the shape of the lateral movement preventing recess 13q coincide with the shape of the outer side 14a of the elastic packing 14, the seating of the elastic packing 14 is improved, the insertion work at the time of assembling the elastic packing is facilitated, and the work efficiency is improved. This is to make it happen.

The cable 12 is obtained by bundling a plurality of covered electric wires 20 or storing them in a tube 12a made of synthetic resin. The thickness of the cable 12 is, for example, 7 types (2 mmφ, 4 mmφ, 6 mmφ, 2 mmφ, 14 mmφ, 8 mmφ, 10 mmφ, 12 mmφ, 14 mmφ) are used.

Next, the configuration for fastening and fixing the plurality of blocks 13 to each other will be described with reference to FIGS. 4, 7, 8, and 10 to 12. The plurality of blocks 13 are attached to each other with head screws 15 (with spring washers 15e). A nut having a female screw 16a screwed into the male screw 15a of the head screw 15 and a knurl 16b formed on the outer peripheral portion thereof in a tightening portion 13g of one block 13B. 16 is inserted non-rotatably by synthetic resin integral molding, and a flaw hole 13h through which the head screw 15 can be loosely penetrated is formed concentrically with the nut 16 in the fastening portion 13g of the other blocks 13A and 13B. A plurality of blocks 13 (1) are inserted by inserting the head screw 15 from the tightening portion 13g of the blocks 13A and 13C of the blocks 13A and 13C and tightening them to the nut 16. A, 13B, 13C) is configured to be secured to each other a high degree of adhesion.

The head 15b of the headed screw 15 is formed with a cross-shaped groove 15c for a plus driver. By inserting a plus driver (not shown) into the cross-shaped groove and rotating the headed screw 15, the screw The screw 15a is screwed into the female screw 16a of the nut 16 so that the blocks 13A and 13C can be easily clamped and fixed to the block 13B, so that the three-piece cable holder 11 is completed as shown in FIG. 1 or FIG. It is configured.
In this case, as shown in FIG. 13, the internal thread 16a of the nut 16 inserted into the block 13B is configured to be shared by the headed screw 15 from the block 13A and the headed screw 15 from the block 13C. At the time of tightening, a sufficient screwing length is set so that the pair of headed screws 15 do not interfere with each other, that is, an appropriate gap C is formed between the tips 15d of the two headed screws 15, 15. Has been.

In the case where the plurality of blocks 13 is a two-piece cable holder 11 including a block 13A and a block 13B, as shown in FIGS. 20 to 22, a female screw 16a and a knurl are attached to a tightening portion 13g of one block 13A. A similar nut 16 formed with 16b is inserted in a non-rotatable manner by integral molding of synthetic resin, and a head hole 15h (not shown) can be loosely inserted into a tightening portion 13g of another block 13B (not shown). (Not shown) is formed concentrically with the nut 16, and a plurality of blocks 13 (13A, 13B) are connected to each other by inserting a headed screw 15 (not shown) from a tightening portion 13g of another block 13B and tightening it to the nut 16. It is configured to be fixed with high adhesion.

Further, two attachment holes 13k for attaching the cable holder 11 to the wall 19 or the like of the casing 18 are formed in the flange portion 13j of each block 13 symmetrically in the longitudinal direction.

Next, a description will be given of a configuration in which the cable holder 11 can be attached to the wall 19 such as the casing 18 from both the front and back sides. A portion that closely contacts the wall 19 such as the casing 18 of the plurality of blocks 13 (13A, 13B, 13C). Are formed on the front surface 13m and the rear surface 13n of the block 13, and are provided on the surface of the wall 19 via the spring washer 23 with a head screw 22; It is configured to be attached from either side of the back surface.
The packing groove 13i is also provided continuously from the packing 13i provided on the back surface 13n on the mating surface 13a of each block, and is configured to obtain a high degree of adhesion when each block is fastened and fixed. The rod-like elastic packing 21 is formed into various shapes by being folded into a considerably complicated shape or cut into short shapes as shown in FIG. 8 in accordance with the complicated shape of the packing groove 13i. Yes.

The present invention is configured as described above, and the operation thereof will be described below.
First, the assembly of the cable holder 11 will be described with reference to FIGS. 13 to 15 with respect to the cable holder 11 including three pieces, that is, the blocks 13A, 13B, and 13C. In FIG. 13, each of the hollow portions 13d formed in the block 13B. Then, the elastic packing 14 in which the concave portion 14b having the radius of curvature matching the diameter of the cable 12 is selected and inserted as shown by the arrow D.

In this case, since the outer side 14a of each elastic packing 14 has the same radius as the lateral movement preventing recess 13q, the elastic packing 14 comes into contact with the entire surface stably and stably.
And since the convex part 13p which is the biggest feature of the present invention completely prevents the lateral movement of the elastic packing 14, the elastic packing 14 inserted one after another does not interfere with each other, and the work is advanced very lightly. be able to. In particular, when the usage is such that all the hollow portions 13d are opened without being used, the operation is very easy as compared with the conventional cable holder 1 (FIGS. 23 and 24). Even if the elastic packing 14 is not inserted into the adjacent hollow portion 13d, the elastic packing 14 never moves laterally. Therefore, even when the block 13 is vibrated or slightly inclined in the vertical direction, the elastic packing 14 is not moved. This is because 14 does not move and is stably fixed at the inserted position.

When all insertion of the elastic packing 14 into the hollow portion 13d of the block 13B is completed, the hollow portion 13d is filled with the elastic packing 14 that can hold the cables 12 having different diameters, as shown in a block 13B in FIG. Assembly is complete.
Subsequently, the elastic packing 14 is inserted into each hollow portion 13d of the block 13A. In this case, the same elastic packing 14 as the elastic packing 14 inserted into each opposing hollow portion 13d of the block 13B is inserted. become. Thus, a hole 14c capable of elastically holding the periphery of the cable 12 is formed by the elastic packings 14 of the overlapped blocks 13B and 13A. The holes 14c may have the same diameter or may be different for each elastic packing 14. In the embodiment shown in FIG. 15, the holes 14c having five types of diameters of 2 mmφ, 4 mmφ, 6 mmφ, 10 mmφ, and 14 mmφ are formed, and thus the cables 12 having these five types of diameters can be held.
When the same elastic packing 14 is inserted into all the hollow portions 13d, as shown in FIG. 2, a total of ten cables 12 having the same diameter, for example, the maximum diameter of 14 mmφ can be held.

Next, the assembly after the elastic packing 14 is inserted into the hollow portion 13d of each block 13 will be described. When the insertion of the elastic packing 14 into the hollow portion 13d of each block 13 is completed, in order to obtain a high degree of adhesion even if it is attached to the wall 19 of the casing 18 from either the front surface 13m or the back surface 13n of the block 13 Since the half of the rod-shaped elastic packing 21 must protrude from the mating surface 13a of each block 13, the rod-shaped elastic packing 21 is pushed into all the packing grooves 13i on the back surface 13n side of each block 13.
However, in the case of normal use in which the cable holder 11 is attached to the wall 19 of the casing 18 from the back surface 13n side, it is not necessary to push the rod-like elastic packing 21 into the packing groove 13i on the front surface 13m side. In the case of mounting from above, the rod-shaped elastic packing 21 is pushed into the packing groove 13i on the surface 13m side.

After the rod-like elastic packing 21 is pushed into the packing groove 13i of each block 13, the necessary number of cables 12 are appropriately passed between the blocks 13A and 13B and between the blocks 13B and 13C, and then FIG. 4, FIG. 8, and FIG. (The cables 12 are not shown in these figures) As shown in FIG. 1, the blocks 13A, 13B, and 13C are brought into close contact with the mating surface 13a in the horizontal direction, and about 1/2 of the diameter protrudes from the mating surface 13a. The rod-shaped elastic packings 21 are brought into close contact with each other and overlapped.

Then, each of the blocks 13A, 13B, and 13C is tightened using the four headed screws 15 via the spring washer 15e. In this case, the knurl 16b inserted into the tightening portion 13g of the block 13B, which is the greatest feature of the present invention. The attached nut 16 demonstrates its power. That is, the two headed screws 15 are first inserted into the hole 13h of the tightening portion 13g of the block 13A, and the male screw 15a is screwed into the female screw 16a of the nut 16 of the tightening portion 13g of the block 13B. (Not shown) is fitted into the cross groove 15c of the head 15b of the head screw 15 and tightened. Since the fitting length of the male screw 15a of the head screw 15 is set to be slightly shorter than ½ of the length of the female screw 16a of the nut 16, the tip 15d of the screw 15a of the nut 16 A gap C shown in FIG. 15 is formed between the tip 15d of the head screw 15 that stops before the center of the length of the screw 16a and is screwed from the block 13C to face each other, and never interferes with each other. By appropriately tightening the head screw 15, each block 13 is tightened while compressing the bar-shaped elastic packing 21 and the spring washer 15 e that slightly protrude from the mating surface 13 a.
Similarly, the block 13C can be fastened to the block 13B by inserting the two headed screws 15 into the hollow holes 13h of the tightening portion 13g of the block 13C and fastening them to the nut 16.

In the cable holder 11 according to the present invention, not only the tightening becomes very simple as described above, but also a very high degree of adhesion is obtained, and the adhesion satisfying IP54 in the degree of protection of solid foreign substances and water, electrical equipment and cabinet. Degree is obtained.
Also, since the nut 16 does not rotate at all, it is possible to tighten each block 13 safely and securely by a very simple operation of simply inserting the four headed screws 15 through the flaw holes 13h and rotating them to the nut 16. The work efficiency is very high, and the assembly work of the cable holder 11 is extremely facilitated.

When the block 13 is a two-piece block 13A and 13C, as shown in FIGS. 20 to 22, the cable 12 is appropriately passed between the blocks 13A and 13C, and then the tightening portion 13g of the block 13C By screwing the male screws 15a of the two headed screws 15 inserted through the holes 13h into the female screws 16a of the nuts 16 inserted into the blocks 13A and tightening, the blocks 13A, 13C can be tightened, and a degree of adhesion satisfying IP54 in the protection grade can be obtained. As shown in FIG. 21, it is of course possible to hold cables 12 of various diameters.

Next, attachment of the completed cable holder 11 to the wall 19 of the casing 18 of the electrical equipment or the like will be described. In the cable holder 11 according to the present invention, the packing groove 13i that can accommodate the rod-like elastic packing 21 is formed on both the front surface 11m and the back surface 11n of each block 13, so that it is shown in FIG. 6, FIG. 16, and FIG. In addition, the head screw 22 can be inserted into the mounting hole 13k via the spring washer 23, and the normal back surface 13n side can be attached to the wall 19, and in this case, the rod-like elastic packing 21 on the back surface 13n side is attached to the wall. 19 is pressed while being compressed, and a high degree of adhesion is obtained.

On the other hand, as shown in FIGS. 18 and 19, it is also possible to push the rod-like elastic packing 21 into the packing groove 13i on the surface 13m side of the block 13 and attach the surface 13m toward the wall 19, in this case. The bar-shaped elastic packing 21 on the back surface 13n side is exclusively used for sealing the mating surface 13a, and the bar-shaped elastic packing 21 on the front surface 13m side is pressed while being compressed by the wall 19 to similarly obtain a high degree of adhesion.

As described above, according to the present invention, the cable holder 11 can be attached to the wall 19 of the casing 18 from both the front and back sides of the cable holder 11. If you want to make it smaller, attach the front surface 13m toward the wall 19, and attach the back surface 13n toward the wall 19 in the normal case where the amount of protrusion does not matter when normal appearance is important. Can be very convenient.
