Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1 to 4 for the embodiment of the short-circuit wire clamp, including base 1, last fastener 2 and two lower fasteners 3, it fixes on base 1 through even board 10 to go up fastener 2, two lower fasteners 3 sets up side by side and surely all lies in the below of fastener 2, every first screw hole 4 has all been opened to the lateral wall of lower fastener 3, even open on board 10 have respectively with two fixed slot 5 that the first screw hole 4 of lower fastener 3 corresponds, second screw hole 6 has still been opened on the base 1 of lower fastener 3 below.

Through two lower fastener 3, press from both sides tightly to the cable with 2 cooperation of going up the fastener respectively, prevent wire jumper position gold utensil wire jumper disconnection, ensure ground connection and connect safety to two lower fastener 3 mutually independent, each other do not influence, also can guarantee simultaneously with the wire jumper end wire the good contact, effectively reduce the safety risk.

Specifically, the base 1 is a rectangular block, the connecting plate 10 is fixed in the middle of the base 1, the connecting plate 10 can also be fixed on the base 1 in a direct welding or clamping manner, and the like, the top end of the connecting plate 10 is fixedly connected with one end of the upper wire clamp 2, in order to ensure enough frontness, the connecting plate 10 and the upper wire clamp 2 can be integrally manufactured or fixed in a welding manner, the upper wire clamp 2 is generally in a semi-circular shape, the concave surface of the upper wire clamp faces the base 1, and the concave surface is the lower groove 7; set up two lower clamps 3 between last fastener 2 and base 1, two lower clamps 3 set up side by side, all opened the upper groove 8 towards last fastener 2 on every lower clamp 3, like this, the hole is embraced tightly to upper groove 8 and the cooperation formation cable of lower groove 7. For the better position of fixed anchor clamps 3 when holding tightly the cable, every anchor clamps 3 all opened first screw hole 4 towards the lateral wall of even board 10, and corresponding position sets up the fixed slot 5 that corresponds with the 4 vertical direction of motion of first screw hole on even board 10, because anchor clamps 3 generally are along vertical direction motion, consequently, fixed slot 5 also is vertical logical groove, just so can pass fixed slot 5 and the cooperation of first screw hole 4 through first bolt 11, do spacingly to four directions all around of anchor clamps 3. And on the base 1 of lower fastener 3 below, then open second screw hole 6, likewise can be through the length of the second bolt 12 twist with second screw hole 6 complex, it is spacing to the high direction about lower fastener 3 to realize the location to lower fastener 3, of course, for better and the bolt contact that passes second screw hole 6, lower fastener 3 generally sets up into the cuboid. The axial direction of a lower groove 7 formed in the lower clamp 3 is parallel to the axial direction of an upper groove 8 formed in the upper clamp 2, and the axial direction of the first threaded hole 4 is perpendicular to the axial direction of the lower groove 7.

Further in order to facilitate the fixed connection of the crimping pipe and the device, two fixing holes 9 are further formed in the base 1 and used for fixing the crimping pipe.

Before carrying out live-wire work at a jumper wire position, firstly, two short wiring clamps are respectively connected and fixed with crimping pipes at two ends of a short wiring, and then the short wiring clamps at two ends of the short wiring are respectively connected and fixed with wires at two ends of a jumper wire, so that a jumper wire part of a circuit is short-circuited. Then live working personnel can carry out live working at the position of the short-circuited jumper. That is, firstly, the crimping pipes at the two ends of the short-circuit wire are respectively inserted into the fixing holes 9 of the two short-circuit wire clamps, then the first bolt 11 and the second bolt 12 are loosened, the wire needing the wire is placed between the upper wire clamp 2 and the lower wire clamp 3, the first bolt 11 and the second bolt 12 of one lower wire clamp 3 are firstly screwed, one lower wire clamp 3 is fixed, and then the first bolt 11 and the second bolt 12 of the second lower wire clamp 3 are screwed, so that the two lower wire clamps 3 are fixed, and the two lower wire clamps are matched with the upper wire clamp 2 to clamp the short circuit of the cable.

Although this device structure is simple, utilize two lower thread clamps 3 respectively with last fastener 2 cooperation, improved whole security, difficult pine takes off and has good conduction performance, easy and simple to handle moreover, as long as with the bolt tightening that corresponds can, promote live working security greatly.

The above description is only for the specific embodiment of the present invention, but the technical features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
