Description

Technical Field

[0001] The utility model relates to the technical field of electric power hardware, in particular to an alloy moment parallel groove equipment wire clamp. Background Art

[0002] Equipment wire clamps are used to connect wires and electrical equipment to transfer electrical loads and withstand certain mechanical loads. Equipment wire clamps are used to connect busbar downleads to the outlet terminals of electrical equipment (such as transformers, circuit breakers, mutual inductors, disconnectors, wall bushings, etc.). Existing equipment wire clamps cannot meet the use requirements of single and double outlets and have poor versatility. When installing the equipment wire clamp, the operator needs to open the wire clamp body and the gland to clamp the wire between the wire clamp body and the gland. As a result, the installation of the equipment wire clamp is cumbersome and the installation efficiency is low. In addition, the wire clamp body and the gland cannot reliably clamp the wire, resulting in an unreliable connection between the wire and the equipment wire clamp. Summary of the invention

[0003] The purpose of the utility model is to overcome the defects of the prior art and provide an alloy torque parallel groove equipment wire clamp with compact structure, convenient installation, stable and reliable performance, reliable connection and good protection performance.

[0004] To achieve the above-mentioned purpose, the utility model adopts an alloy torque parallel groove equipment wire clamp, including an insulating cover, a wire clamp assembly arranged in the insulating cover, and an insulating cover cover arranged on the insulating cover and covering the wire clamp assembly. The wire clamp assembly includes a wire clamp body arranged in the insulating cover, a pressure cover arranged on the wire clamp body, a pressure block arranged on the pressure cover, a plurality of bolts, and a plurality of torque nuts. The plurality of bolts respectively pass through the wire clamp body, the pressure cover, and the pressure block and are tightened with a plurality of torque nuts. Springs are respectively mounted on the plurality of bolts at locations corresponding to between the wire clamp body and the pressure cover. Two clamping cavities for clamping the wire are formed between the wire clamp body and the pressure cover. A conductive plate is provided on one side of the wire clamp body, and connection holes are respectively provided on the conductive plate.

[0005] The beneficial effects of the above structure are: the equipment wire clamp adopts a parallel groove structure design, and two clamping cavities are formed between the gland and the wire clamp body, so that the equipment wire clamp can meet the use requirements of single and double outlets. A spring is arranged between the wire clamp body and the gland. During installation, the spring can open the wire clamp body and the gland, thereby facilitating the installation of the equipment wire clamp and the wire, and the installation is more convenient. The wire clamp assembly is arranged in the insulating cover and the insulating cover, and the protective performance is better. Therefore, the parallel groove equipment wire clamp has the advantages of compact structure, convenient installation, stable and reliable performance, reliable connection, and good protective performance.

[0006] In particular, a positioning groove is provided on the wire clamp body corresponding to the spring, one end of the spring abuts in the positioning groove, and the other end of the spring abuts against the inner wall of the gland. The positioning groove of the wire clamp body plays a positioning role for the spring, which can ensure the elastic force stability of the spring. During installation, the elastic force of the spring can open the wire clamp body and the gland, thereby facilitating the installation of the parallel groove equipment wire clamp and the wire, and the installation efficiency is higher.

[0007] In particular, the pressing block is provided with an arc groove, and the arc groove fits on the upper end surface of the pressure cover. The arc groove of the pressing block fits on the pressure cover, thereby preventing the pressing block from sliding on the pressure cover at will, thereby ensuring a more compact connection between the pressure covers.

[0008] In particular, the wire clamp body is symmetrically provided with two wire placement grooves, the pressure cover is provided with two wire pressing grooves matching the two wire placement grooves, and the two clamping cavities are formed between the two wire placement grooves and the two wire pressing grooves. The wire placement groove of the wire clamp body and the wire pressing groove of the pressure cover can be clamped on the wire, thereby ensuring that the wire clamp body and the pressure cover can reliably clamp the wire, and the reliability of the connection is higher.

[0009] In particular, the insulating cover is provided with a plurality of hooks, and the insulating cover is provided with a plurality of holes matched with the hooks. The hooks are engaged in the holes and form a snap fit between the insulating cover and the insulating cover. Two threading holes are formed at one end of the insulating cover and the insulating cover corresponding to the two clamping cavities, and the other end of the insulating cover and the insulating cover has a wiring hole for accommodating the conductive plate. The insulating cover and the insulating cover are connected by snap fit, so that the assembly of the insulating cover and the insulating cover is convenient, the assembly efficiency is higher, and the insulating cover and the insulating cover can play a protective role, which is conducive to improving the protective performance of the parallel groove equipment wire clamp.
