Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheath gripping section at a cable connection section.

At the cable connection part, it is required to firmly grip the sheath in order to resist the tension applied to this part.

For this type of sheath gripping part, for example, a clamp fitting split in half and having a large number of protrusions formed on the inner surface is fitted onto the sheath, this clamp fitting is tightened by a fixing means, and the protrusions are inserted into the sheath. Some grip the sheath by pushing it in.

However, in this type of gripping part, there are variations in the degree of machining of the protrusions formed on the inner surface of the clamp fitting.
Correspondingly, the gripping force also varied, which was not necessarily preferable.

The present invention provides a cable sheath gripping part that eliminates such drawbacks, and its gist is that a cylindrical body with an inner diameter approximately equal to the inner diameter of the cable sheath is attached to the end of the cable sheath having an axial cut. A core having a large number of protrusions provided corresponding to the direction and length of the cuts is fitted and arranged on the surface of the caple sheath so that the protrusions protrude outward from the cuts, and the outer diameter of the cable sheath is A clamp fitting has a halved cylindrical portion with an inner diameter approximately equal to the diameter of the cable, and is provided with a protrusion insertion hole corresponding to the protrusion of the core inserted into the end of the cable sheath. The protrusion of the core is placed on the outside of the sheath so as to fit into the insertion hole of the clamp fitting, and the two-split clamp fitting is tightened and fixed by a fixing means.

Hereinafter, the present invention will be explained in detail based on examples.

FIG. 1 is a perspective view showing various structural elements constituting a sheath gripping section according to the present invention.

In the figure, reference numeral 7 denotes the end of the cable, and the sheath 8 has a plurality of slits 18 of appropriate length formed in the axial direction from the tip.

9 is a cable core. Reference numeral 20 denotes a core, which is made up of a cylindrical body 21 having an inner diameter approximately equal to the inner diameter of the cable sheath 8, and a large number of protrusions 22 formed on the outer surface thereof at positions corresponding to the cuts 18 of the sheath 8, and the length of the protrusions is The length is made longer than the thickness of the sheath 8.

Reference numeral 23 denotes a split clamp fitting, and 24 indicates a semi-cylindrical part provided at the center thereof, and the inner diameter of the combined cylindrical part is approximately equal to the outer diameter of the cable sheath 8.

A large number of projection insertion holes 26 are formed in this cylindrical portion 24 at positions corresponding to the projections 22 of the core 20.

Reference numeral 25 denotes an extension extending laterally from the cylindrical portion 24, and is provided with a threaded hole 27 into which a bolt 28 is screwed.

2 and 3 show a cable sheath gripper in which each of the structural elements shown in FIG. 1 is applied to the cable end.

In the figure, the core 20 is inserted between the cable core 9 and the sheath 8 so as to protrude from the cut 18 of the sheath 8.

Further, the split clamp fitting 23 is arranged on the cable sheath 8 with the core 20 located inside, by fitting the protrusion 22 protruding from the cut 18 of the sheath 8 of the core 20 into the insertion hole 26 thereof. has been done.

The clamp fitting 23 is tightened by the bolt 28 and firmly grips the sheath 8.

Reference numeral 10 denotes a bracket that is fitted and fixed onto the cable end by a fixing means (not shown), and is also provided on the other cable end (not shown) to be connected, and both are connected to the tension member 15. are interconnected through.

The clamp fitting 23 is fixed to this bracket 10 by appropriate fixing means.

The tension applied to the cable end 7 is counteracted by the cable sheath gripper and the tension member according to the invention.

In the sheath gripping part according to the present invention, the core provided with the protrusion as described above is inserted between the cable core and the sheath cut so that the protrusion protrudes from the sheath cut, and the core is further positioned inside. A split clamp fitting having an insertion hole into which the protrusion is inserted is placed on a sheath having a cut, with the protrusion inserted into the insertion hole, and this clamp fitting is tightened and fixed by a fixing means.
To provide a cable sheath gripping part that has no variation in its tightening force and can sufficiently withstand the tension applied to the cable.
I can do it.
