Embodiment 1

[0047] Such as figure 1 As shown, a split-type wire lug 4 includes a wire connecting pipe 4.4 and a ring, and the ring includes an upper ring 4.2, a lower ring 4.3 and a connecting part 4.1, wherein,

[0048] One end of the upper ring 4.2 is connected with one end of the connecting part 4.1;

[0049] The other end of the upper ring 4.2 is connected to the other end of the lower ring 4.3;

[0050] One end of the lower ring 4.3 is connected to the other end of the connecting part 4.1;

[0051] The lower ring 4.3 is connected with the wire connecting pipe 4.4.

[0052] In this embodiment, the ring has the function of opening and closing through the upper ring, the lower ring and the connecting parts, so that the ring can be taken off directly. Avoid needing to unscrew the nut all the way from the threaded rod to remove the lug.

[0053] In Embodiment 1, the following improvements can also be made: the connecting part 4.1 is a rotatable part, and the upper ring 4.2, the lower ...

Embodiment 2

[0067] Embodiment 2 is an extended example of Embodiment 1.

[0068] A connection structure, including the split-type wire lug 4 of Embodiment 1, and also includes bolts 2, nuts 3, grounding wires 5 and grounding rods 6, wherein,

[0069] The bolt 2 includes a head and a screw rod, the head is arranged on one end of the screw rod 2, and the head is fixedly connected with the screw rod 2;

[0070] The other end of the screw rod is meshed with the ground rod 6;

[0071] The nut 3 rotates and moves on the screw rod;

[0072] The wire connecting pipe 4.4 is connected with the ground wire 5;

[0073] The split-type wire lug 4 is located between the nut 3 and the grounding rod 6, and the nut 3 realizes a position-limiting function.

[0074] The course of work of embodiment 2:

[0075] Install the ground wire: turn the nut outward slightly, open the open-closed wire lug, insert it to the position to be connected, close the open-closed wire lug, and can choose to add a lock to loc...

Abstract

The invention discloses an open-close type wire nose which comprises a wire connecting pipe and a circular ring, and the circular ring comprises an upper ring, a lower ring and a connecting part; oneend of the upper ring is connected with one end of the connecting part, and the other end of the upper ring is connected with the other end of the lower ring; one end of the lower ring is connected with the other end of the connecting part; and the lower ring is connected with the wire connecting pipe. The invention further discloses a connecting structure comprising the open-close type wire nose.According to the invention, an employee can easily take down the wire nose connected with the grounding wire under the condition that the nut is slightly moved, thereby reducing the rotation stroke length of the nut in a disassembly and assembly process, reducing the working time for disassembling and assembling the grounding wire, and improving the working efficiency.

Description

technical field [0001] The invention relates to the field of power system equipment, and more specifically, to a split-type wire lug and its connection structure. Background technique [0002] Before the maintenance of power equipment, after verifying that the equipment has no voltage, short-circuit the three phases and ground them through the ground wire, which is an important way to ensure the safety of the power workers and the power grid. According to the requirements of "Electricity (Industry) Safety Work Regulations", during the maintenance of electric equipment or lines, it is necessary to go through power failure, power inspection, and grounding before permitting work. Therefore, portable short-circuit grounding wires are widely used in power generation, power transformation, power transmission, power distribution, and power consumption that involve power failure and grounding. For the ground terminal, the connection between the ground wire and the ground terminal m...
