Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a cable clamp.

[Problems to be solved by conventional techniques and devices]

Generally, the cable is held by a cable clamp at a branching portion or the like, but as shown in the simplified plan view of the conventional example of FIG. 6 and the simplified side view of FIG. 7, the cable a ...
Even if there are a plurality (three), each clamp b is used for each cable a. That is, the clamp b is composed of upper and lower blocks c and d, a recess e is provided on the lower surface of the upper block c, and a recess f facing the recess e is provided on the upper surface of the lower block d, and While the cable a was fitted in the recesses e and f, the upper and lower blocks c and d were connected by the tightening bolts g and g to hold the cable a in a pinching state.

Therefore, the distance between the cables a must be relatively large, and a large amount of wasted space must be taken.
Also, in order to reduce such a space, it is sufficient to hold three cables with one clamp, but in this case, when the outer diameter dimensions of the cables differ within a predetermined design tolerance range. However, when tightening the upper and lower blocks, it was not possible to clamp three at the same time.

Therefore, it is an object of the present invention to provide a cable clamp that can eliminate unnecessary space as much as possible and can reliably clamp three cables.

[Means for Solving the Problems]

To achieve the above object, a cable clamp according to the present invention is a cable clamp including first and second blocks that are tightened and connected in a direction approaching each other; The three semi-circular recesses are formed on the surface corresponding to the two blocks, and the first block of the second block is formed.
Three semi-circular concave portions corresponding to the respective semi-circular concave portions of the first block are formed on the block corresponding surface, and deformation is allowed between either one of the concave portions of the first and second blocks. A slit portion for use is formed.

[Action]

If the first and second blocks are formed in an overlapping shape so that the corresponding surfaces correspond to each other, each recess forms three hole-shaped cable fitting portions. When the cables are inserted into the respective cable fitting portions and the first and second cables are tightened in the directions in which they approach each other, the inner diameter of the fitting portions is reduced, and each cable is fitted into the fitting portion. It is fixed to.

If the outer diameters of the cables differ from each other,
When the first and second blocks are tightened, the cable having the maximum outer diameter is first fixedly held in the corresponding fitting portion. At this time, the other cables are in a so-called free state without being held by the corresponding fitting portions. Then, by further tightening the first and second blocks from this state, in the block provided with the slit portion, the large-diameter cable deforms in the vicinity of the concave portion into which the large-diameter cable is fitted. However, it deforms in the vicinity of the other recesses, and the small-diameter cable is also fixedly held.

〔Example〕

 Hereinafter, embodiments will be described with reference to the drawings.

FIG. 3 shows a simplified perspective view of a cable clamp according to the present invention in use, which includes three cables 1a, 1.
It holds b and 1c in a fixed manner, and is provided with first and second blocks 2 and 3 which are tightened in directions toward each other.

Then, the first block 2 is formed of a substantially rectangular parallelepiped,
As shown in the enlarged cross-sectional view showing one embodiment of the present invention, three semicircular recesses 5, 6, 7 are formed in the second block corresponding surface 4, and between the recesses 5, 6 and the recess 6 Deformation-permitting slits 8 and 8 are formed on the corresponding surface 4 between the slits 7 and 7. Further, through holes 9, 9 are provided at both ends of the first block 2.

Next, like the first block 2, the second block 3 is formed of a substantially rectangular parallelepiped, and the concave portion 5, 6,
Semicircular recesses 11, 12, 13 corresponding to 7 are formed. Further, at both ends of the first block corresponding surface 10, screw holes 14, 14 are provided.
Is provided.

Then, in the state where the corresponding surfaces 4 and 10 are superposed so as to correspond to each other, the recessed portions 5 and 11 form the hole-shaped cable fitting portion 16 through which the cable 1a is inserted, and the recessed portions 6 and 12 are formed. Thus, a hole-shaped cable fitting portion 17 through which the cable 1b is inserted is formed, and a hole-shaped cable fitting portion 18 through which the cable 1c is inserted is formed by the recesses 7 and 13. Also,
At this time, the axial centers of the corresponding through hole 9 and screw hole 14 are aligned.

FIG. 2 shows an enlarged sectional view of the clamped state of the cable,
In this case, the outer diameter dimension Db of the central cable 1b is set to be larger than the outer diameter dimensions Da and Dc of the other cables 1a and 1c, and the other cable 1
The outer diameters Da and Dc of a and 1c are almost the same. In addition,
Of course, the outer diameter dimensions Da and Dc may be different.

Therefore, in such a case, the first and second blocks 2 and 3 are overlapped with each other, and the cables 1a, 1b and 1c are fitted with the cable fitting portions 16, 17 and 18, and the tightening bolts are 19,19
Is inserted into the through holes 9 and 9 of the first block 2 and screwed into the screw holes 14 and 14 of the second block 3, and the tightening bolts 19 and 19 of the screw are advanced first to the center. Cable 1b
Has a larger diameter than the other cables 1a and 1c, and is fixedly held by the fitting portion 17 as shown in the figure. Further, when the tightening bolts 19 and 19 are screwed in, the slits 8 and 8 are provided in the first block 2, so the first block 2
The central portion of the is no closer to the second block 3 due to the central cable 1b, but both ends of the first block 2 are
The second block 3 is sequentially approached. Therefore, the mating parts 16, 18
The inner diameter of the cable is reduced, and the cables 1a and 1c are
It is fixedly held by the corresponding fitting portions 16 and 18.

Next, in Fig. 4, the central cable 1b is replaced with the other cables 1a and 1c.
FIG. 3 is an enlarged cross-sectional view showing a case of a smaller diameter, in which case an outer frame body (not shown) on which the cable clamp is provided
A pressing member 20 is additionally provided, and the pressing member 20 is used for the first block 2
If the central portion of the is pressed downward as indicated by the arrow, the central cable 1b that has not been tightened with the tightening bolts 19 and 19 can be tightened.

FIG. 5 shows an enlarged cross-sectional view of another embodiment, in which the slit portions 8 and 8 are the upper surface 2 between the concave portions 5 and 6 and the concave portions 6 and 7.
It is provided in 1. That is, even in this case, if the tightening bolts 19 and 19 are screwed, the cables 1a, 1b and 1c can be reliably held even if the outer diameters are different.

It should be noted that the present invention is not limited to the above-described embodiment, and design changes can be freely made without departing from the scope of the present invention. For example, the slit portion 8 is not formed in the first block 2 and the second block 3 is formed. The slit portion 8 may be formed freely, and the depth dimension and width dimension of the slit portion 8 may be freely set. However, if the slit portion 8 is too large, the slit portion 8 may be deformed too much, as shown in FIG. In such a case, the cable 1b at the center is not tightened, and if the slit portion 8 is too small, it is difficult to deform and the cables 1a and 1c at the ends are not tightened. It is preferable to determine the size of the slit portion 8 in consideration of the material and the like. Furthermore, the number of tightening bolts 19 is not limited to two, and the number thereof can be increased freely.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

The three cables 1a, 1b, 1c having different outer diameters Da, Db, Dc can be securely held, and the respective cables 1a, 1b, 1c
Since 1c is not held by three clamps of separate members, the distance between the cables 1a, 1b, 1c does not become large,
No extra space needed. Also, the structure is simple, easy to manufacture and easy to use,
There is also an advantage that the cost is not high.
