A screwless C-type wire clamp

Abstract

The invention discloses a screwless C type wire clamp which comprises a compact block and a C-shaped element. The compact block is composed of two compact bodies. One end of each compact body is provided with a crescent-shaped projection cooperating with the C-shaped element. The side surface of the other end of each compact body is connected with a pressing-in block through a spring piece. The central parts of the upper end face splicing parts of the two compact bodies are provided with one conical screw hole. The two sides of the conical screw hole are respectively provided with a protruding contraposition point and a recessed contraposition point which cooperate with each other. The manufacturing cost of the screwless C type wire clamp is not high. Compared with conventional C type wire clamps, the wire clamp with no screws brings greater convenience when insulating or waterproof processing is performed on the outer side of the wire clamp. The overall appearance of the wire clamp is regular and attractive. Meanwhile, the wire clamp can be used for arranging glue pouring type joints overhead and providing possibilities of better reducing phenomena of water entries into insulation wires on the premise that great electrical performance is maintained.

Description

technical field [0001] The invention relates to a C-type wire clamp, more specifically, it relates to a screwless C-type wire clamp mainly used for connecting various types of electric wires. Background technique [0002] In the construction of electric power engineering, C-type clamps have been widely used in the connection of various power conductors because of their large contact area, strong overload capacity, reliable crimping and fastening, good thermal cycle performance, and convenient installation. . When the insulated wire is connected, an insulating cover is often added outside the C-shaped clamp to improve the insulation level of the line and increase the watertightness, and reduce the occurrence of insulated wire or cable water ingress. Adding an insulating cover to the C-type clamp cannot solve the problem of water ingress in overhead insulated wires. Although waterproof tape and conductive paste are used in the insulating cover, the actual situation is that a...

Problems solved by technology

The waterproof effect of glue-filled joints is relatively better, but this type of joints is large in size and heavy in weight, and more of them are only used on the ground. Beautiful, the second is to make the glue-filled joint bulky and cannot be reduced, which further reduces the possibility of overhead use of the glue-filled joint

The left and right sides of the internal hinge structure of the C-type cable clamp cannot be guaranteed to be 100% in the same line, and there is vibration in the running wire, so under normal circumstances, the screw cannot be canceled
