Embodiment Construction

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] Now, a parallel groove clamp provided by the present invention will be described. see Figure 1 to Figure 4 , a parallel groove clamp, including a connecting sleeve 1, a pressure block 2, a drive assembly 3 and a non-return member 4.

[0035] Two pressure blocks 2 are slidably arranged in the connection sleeve 1, and the ends of the two pressure blocks 2 away from each other respectively form a crimping space for crimping the wire with the inner wall of the connection sleeve 1; the drive assembly 3 is arranged in the connection sleeve 1 on, used to drive t...

Abstract

The invention provides a parallel groove clamp, and belongs to the technical field of power wiring equipment. The parallel groove clamp comprises a connecting sleeve, pressing blocks, a driving assembly and stop pieces. The two pressing blocks are slidably arranged in the connecting sleeve, and one ends, away from each other, of the two pressing blocks are connected with the inner wall of the connecting sleeve to form a crimping space separately; the driving assembly is arranged on the connecting sleeve; and the two stop pieces are arranged on the connecting sleeve and are in one-to-one correspondence with the two pressing blocks. According to the parallel groove clamp provided by the invention, two wires penetrate into the crimping space formed by the ends, far away from each other, of the two pressing blocks, and the inner wall of the connecting sleeve; the driving assembly drives the two pressing blocks to be far away from each other, and the two wires are pressed in the crimping space separately, and the pressing blocks of the wires are fixed and tightened through the two stop pieces respectively; and when the wire is connected in the high-altitude operation, an operator does not need to carry tools for tightening bolts, and the wire connection can be completed only by using the driving assembly, so that the operation difficulty is reduced, and the risk that a tool falls from a high altitude to a person is avoided.

Description

technical field [0001] The invention belongs to the technical field of electric power connection equipment, and more specifically relates to a ditch parallel clamp. Background technique [0002] The parallel trench clamp is used for the connection of small and medium-sized aluminum stranded wires or steel-cored aluminum stranded wires and the steel stranded wires of overhead lightning conductors at positions that do not bear tension, and is also used for jumper connections of non-linear pole towers. Power engineering materials (fittings) are used to connect wires to each other, and are mainly used in power line engineering. [0003] A conventional ditch parallel clamp is composed of two stacked clips and at least one bolt, and the distance between the two clips is adjusted by rotating the bolt to connect at least two wires. When using parallel groove clamps to connect wires in high-altitude operations, it is often troublesome for operators to carry tools for tightening bolt...
