specific Embodiment approach 1

[0013] Specific Embodiment 1: A grounding wire clamp in this embodiment includes a grounding wire clamp body 1 and a sleeve 2 connected to an insulating pull rod. The grounding wire clamp body 1 is provided with a chuck, which is characterized in that the sleeve 2 is made of The straight tube body 3 and the trumpet tube body 4 are composed of the straight tube body 3 and the narrow mouth end of the horn tube body 4 buttted into one structure, and the tube wall of the horn tube body 4 is along the horn type The pipe body 4 is provided with a long first channel 4-1 in the axial direction, and the second channel 3-1 is opened along the axial direction of the straight tube body 3 on the tube wall of the straight tube body 3, and the first channel 4 -1 communicates with the second tunnel 3-1, and there is a turning tunnel 3-2 perpendicular to the second tunnel 3-1 on one side of the closed end of the second tunnel 3-1, and one end of the steering tunnel 3-2 is connected to the secon...

specific Embodiment approach 2

[0018] Embodiment 2: This embodiment differs from Embodiment 1 in that: the ground wire clamp body 1 and the sleeve 2 are connected by metal crimping, and the interfaces on both sides are reinforced with rivets. Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0019] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the material of the ground wire clip body 1 is cast aluminum alloy. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to the field of ground lead mounting safety protection of transformer substations, overhead transmission lines, distributing lines and cable lines in the electric power industry, in particular to a ground lead clip. The ground lead clip aims at solving the problems that time consumed when a traditional ground lead clip is disassembled is long, the physical ability of operating personnel is seriously affected due to long-time continuous operation, and hidden dangers are brought to safe operation. The ground lead clip comprises a ground conductor clip body and a sleeve connected with an insulating pull rod, wherein the ground conductor clip body is provided with a clip head, the sleeve is composed of a cylindrical tube and a horn-type tube, the cylindrical tube and the narrow end of the horn-type tube are in butt joint to be of an integrated structure, a first through pore passage is formed in the wall of the horn-type tube, a second pore passage is formed in the wall of the cylindrical tube, a steering pore passage is formed in one side of the closed end of the second pore passage and is perpendicular to the second pore passage, and a first positioning and clamping hole and a second positioning and clamping hole are formed in the two sides of one end portion of the steering pore passage.

Description

technical field [0001] The invention relates to the field of safety protection for installation of substations, overhead transmission lines, power distribution lines and cable lines in the electric power industry, and in particular relates to a ground wire clamp. Background technique [0002] The connection part of the traditional grounding wire clamp and the insulating tie rod is a straight-through connection. In order to ensure a tight and reliable connection, the sleeve of the wire clamp is designed as a straight cylinder, and the size of the sleeve is almost the same as that of the metal rod of the insulating tie rod. Although this design ensures that the ground wire clamp does not disengage and does not shake during the installation of the ground wire, which ensures safety, but when the ground wire is removed, because the drainage wire is relatively high from the ground, generally 4-5 meters, it will When the metal rod of the insulating tie rod is inserted into the conn...
