A kind of double C type elastic wiring device

Abstract

The invention provides a double-C-shaped elastic wiring device, and belongs to the field of electricity. The double-C-shaped elastic wiring device is formed by a double-C-shaped double-opening elastic wire clamp, a cup head square neck bolt and a hexagon flange nut. The double-C-shaped double-opening elastic wire clamp comprises a first C-shaped curved surface component and a second C-shaped curved surface component. The open end of the first C-shaped curved surface component is provided with a first extended straight edge and a second extended bevel edge, the other end of the second extended bevel edge is connected with one end of the open end of the second C-shaped curved surface component, and a third extended straight edge is arranged at the other end of the open end of the second C-shaped curved surface component. A regular polygonal hole is formed in a support. The cup head square neck bolt is arranged in the regular polygonal hole. The cup head square neck bolt penetrates a first bolt hole, a long hole and a second bolt hole to be connected with the hexagon flange nut in a rotating and fastening mode. Rapid fastening of a wire can be achieved by the utilization of only one socket wrench, equipment hot-line wiring operation can be performed on an electric pole conveniently, and the double-C-shaped elastic wiring device is suitable for wiring of two wires of different diameters at the same time and can guarantee the personal safety of operators in the operation process.

Description

technical field [0001] The invention belongs to the field of electricity, and in particular relates to a connecting device for conveniently connecting wires of two specifications. Background technique [0002] With the increasing development of urbanization and power supply construction, higher and higher requirements are put forward for the production, safety and maintenance of power supply lines and related equipment. [0003] The wiring operation of power supply lines and their equipment is closely related to the maintenance and safety of line equipment. [0004] In the past, for the wiring of the equipment on the concrete pole of the power supply line, the crimping clamp (commonly known as the wiring clamp in the industry, generally used for the connection of single or two wires, such as figure 1 shown), which uses two upper and lower pressure plates (indicated by a, b in the figure), at least two sets of hexagonal bolts (d1, d2), two sets of hexagonal nuts (c1, c2), an...

Problems solved by technology

To compress the wires, the operator must hold a wrench in each hand, and tighten the nuts and bolts at the same time to compress the wires; and for the operators who perform live operations on the poles, it is not necessary to operate live with both hands at close range. Realistic; and when carrying out live work, the operator must use two sets of insulated fastening tools at the same time to carry out the fastening operation of the bolts. The fastening quality is not good, which leads to the connection wire heating at the connection point, the serious oxidation of the wire and the failure of the connection quality, and the personal safety of the operator during the fastening bolt process cannot be guaranteed.

[0005] In addition, due to the connecting wire of Shanghai power supply line equipment, there is a 25mm 2 and 35mm 2 The wires of two specifications need to be equipped with crimping clamps of different specifications in order to adapt to wires of different diameters, which also increases the variety, specifications and quantity of spare parts, which is not conducive to reducing the quantity of spare parts and management costs.
