What is a wedge-shaped parallel groove clamp? What are the usage features?

【概要描述】

Parallel groove clamp is a very important wiring connector although it seems insignificant in power use. The traditional H-type aluminum crimping clamp has some disadvantages, such as non reuse, non disassembly and so on. For the use in some parts of China, due to the use of ejection gun during installation, the compression deviation is easy to occur during the compression process, resulting in the problem that one of the wires or cables is too tight and the other side of the cable or wire is too loose, resulting in poor connection effect.

The inner wedge block of the wedge-shaped parallel groove clamp is provided with an axisymmetric scale, which is used to distinguish the compression and tightness of wires or wires on both sides, and can improve the connection effect of wires or cables as a whole. The utility model comprises a wire clamp base, which is provided with a wire clamp groove. The clamp slot includes a semicircular slot on both sides and a wedge slot connecting the two slots. The clamp groove is matched with an inner wedge, and the side wall of the inner wedge is provided with an inner groove matched with the semicircular wire groove. The utility model is characterized in that the upper end face of the inner wedge block is provided with a plurality of spaced scribed lines, the spacing of the scribed lines is equal diameter, and the center line of the upper end face of the wedge block within the scribed line is a symmetrical line, distributed on the left and right sides. The scribed lines are distributed from the middle to both sides and straight to the edge of the upper end face. When the conductor or cable is inserted into the wire trench on both sides, the conductor or cable is compressed by driving the wedge block to move towards the side with small diameter of the clamp slot. During compression, the compression of wires and cables on the left and right sides is judged by observing the coverage of scribed lines on the inner wedge, so as to provide the connection effect of wires and cables.

On the basis of meeting the national standards, Dapeng power adopts good materials to improve the shortcomings in the clamp. Its design is reasonable. The clamp has been changed without affecting the power transmission performance and stable and reliable performance of the clamp. The utility model is conducive to the protection of the transmission line, saves materials, reduces weight and reduces the use cost of the clamp. The power wedge parallel groove clamp can be suitable for the connection project of steel strand, aluminum strand or steel cored aluminum strand of overhead power lines.
