Description

{SHIELD CLAMP FOR HIGH VOLTAGE CABLE}

The present invention relates to a shield clamp for a high-voltage cable that can be shielded by squeezing with a braid wire and a sheath of a high-voltage cable.

Generally, high voltage cables are used in automobiles. The high-voltage cable has a core wire with a high voltage in the center, the core wire is wrapped by an insulator, the insulator is covered with a shielding braid, and the braid wire is wrapped with an insulating sheath.

Here, in order to individually shield high-voltage cables, two parts, a shield clamp and a shield ring, are required. That is, a method in which a braided wire is sandwiched between a shield clamp and a shield ring is used.

However, in order to individually shield a high-voltage cable, a shield clamp and a shield ring must be provided together, and it is inconvenient to work each one sequentially.

In recent years, an integral type in which a shield clamp or a shield ring is integrated is used for improving workability and cost reduction.

However, the integrated type has a problem that it is difficult to expect the shielding performance to be superior to the detachable type because the contact (end) portions of the clamping member are opposed to each other and the circular holding is difficult, and there is also a problem of low coupling force with the clamp.

SUMMARY OF THE INVENTION A problem to be solved by the present invention is to provide a shield clamp for a high voltage cable capable of improving a shielding performance by simultaneously pressing a first crimping portion for crimping a braid wire of a high voltage cable and a second crimping portion for crimping a sheath I would like to.

A shield clamp for a high-voltage cable according to the present invention is a shield clamp for a high-voltage cable, comprising: a first clamping member (1) which is clamped and fixed to a weaving line (1) while the outer circumferential surface of the weaving line A second squeezing portion 20 which is pressed and fixed to the sheath 2 in such a state that the outer peripheral surface of the sheath 2 is tightened while both ends of the sheath 2 are staggered by wrapping the sheath 2 by external pressure, And a connecting portion 30 which is integrally connected between the first crimping portion 10 and the second crimping portion 20 and which shields the crimped portion between the woven wire 1 and the sheath 2 .

The present invention is characterized in that a first crimping section for crimping a knitting line of a high voltage cable and a second crimping section for crimping a sheath are simultaneously pressed to a circular shape so that the outer circumferential surface of the knitting line is in close contact with the inner circumferential surface of the first crimping section, It is possible to improve the shielding performance by being brought into close contact with the inner peripheral surface of the crimping portion.

In addition, the connecting portion connecting the first pressing portion pressing the braided wire to the second pressing portion pressing the sheath is bent so that the step formed between the braided wire and the sheath can be easily shielded.

1 is a perspective view of a shield clamp for a high voltage cable according to the present invention;
2 is a perspective view showing a state before the present invention is fastened to a high-voltage cable;
3 is a perspective view showing a state in which the present invention is in close contact with an outer peripheral surface of a high voltage cable;
4 is a side view showing a state where the present invention is pressed and fixed to the outer circumferential surface of a high voltage cable;

Hereinafter, a shield clamp for a high voltage cable according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 4, the shield clamp for a high voltage cable of the present invention includes a first crimping portion 10, a second crimping portion 20, and a connecting portion 30.

The first pressing portion 10 is pressed and fixed to the braiding line 1 in a state in which both ends of the braiding line 1 are wrapped around by the external pressure so that both ends do not come into contact with each other or overlap each other and are stitched on the outer circumferential surface of the braiding line 1 . The first pressing portion 10 is formed in a triangular shape that is staggered with respect to the first end 11 on both sides so that the first side ends 11 of the first side are gathered together and are not overlapped with each other while surrounding the braiding line 1 in a barrel shape. . Therefore, since the first ends 11 are staggered by external pressure and are formed into a barrel shape, it is possible to easily cope with the braiding lines 1 manufactured with diameters of various sizes. Also, it is preferable that the first end 11 of the first pressing portion 10 is cut or rounded so as to eliminate the pointed sharpness. Therefore, it is possible to prevent a user from being injured or damaging the braided cord 1 in the process of pressing the first crimped portion 10.

The second pressing portion 20 is pressed and fixed to the sheath 2 while the sheath 2 is wrapped around by the external pressure so that the opposite ends of the second pressing portion 20 are stitched without being overlapped or overlapped with each other so as to tighten the outer peripheral surface of the sheath 2. The second crimping portion 20 is formed in such a manner that the second end portions 21 of the second crimping portion 20 are joined to each other so as not to overlap each other while wrapping the crimping wire 1 in a barrel shape, . Therefore, since the second ends 21 are staggered and interlocked with each other due to an external pressure, they are formed in a barrel shape, so that the sheaths 2 manufactured with diameters of various sizes can be easily handled. The second end 21 of the second crimping portion 20 is preferably cut or rounded so as to eliminate a pointed sharpness. Therefore, it is possible to prevent a user from being injured or damaged by the process of pressing the second press portion 20. The second crimping portion 20 is preferably formed to have a wider area than the first crimping portion 10 so as to enclose the outer circumferential surface of the sheath 2 having a diameter larger than that of the woven wire 1. [

The connecting portion 30 is integrally connected between the first pressing portion 10 and the second pressing portion 20 so as to be shielded while compressing between the weaving line 1 and the sheath 2. The connecting portion 30 is provided between the first pressing portion 10 and the second pressing portion 20 so as to easily block the step portion generated by the difference in diameter between the braiding wire 1 and the sheath 2 As shown in Fig.

In this way, in a state in which the first press portion 10 is positioned on the weaving line 1 and the second press portion 20 is positioned on the sheath 2, The first pressing portion 10 is pressed so as to be squeezed in the form of a barrel on the outer circumferential surface of the sheath 2 and the second pressing portion 20 is pressed so that the second pressing portion 20 is pressed on the outer circumferential surface of the sheath 2 in a barrel- do. At this time, the connection portion 30 is also brought into close contact with the sheath 2 by the crimping of the first crimping portion 10 and the second crimping portion 20.

At this time, the second ends 21, which are staggered in a triangular shape, are staggered on both sides of the second squeezing portion 20 and are stitched on the outer peripheral surface of the sheath 2 in a barrel- The first ends 11, which are staggered in a triangular shape, are staggered without being overlapped with each other, and are pressed onto the outer peripheral surface of the braid 1 in a barrel shape.

The first and second ends 11 and 21 of the first and second crimping portions 10 and 20 are formed in a triangular shape so that they do not overlap with each other, ) And the sheath (2), the shielding performance can be improved.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is to be understood, therefore, that the embodiments described above are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, and the meaning and scope of the claims and their equivalents All changes or modifications that come within the scope of the present invention should be construed as being included within the scope of the present invention.
