A secondary cable core insulation protection clamp

Abstract

The invention discloses an insulating protection clamp for a secondary cable core. The insulating protection clamp comprises a base, an insulating housing and a spring clamp, wherein the insulating housing is fixed on the base; a wire core inserting hole is formed in the side surface of the insulating housing; the spring clamp is arranged in the wire core inserting hole and comprises a spring, an upper clamping piece and a lower clamping piece; a spring is arranged at the middle parts of the upper clamping piece and the lower clamping piece and is connected with the upper clamping piece and the lower clamping piece; the clamping piece at the lower part is fixed on the bottom surface of the wire core inserting hole; a groove is formed in the top part of the insulating housing; a through hole communicating with the wire core inserting hole is formed in the middle part of the bottom surface of the groove; a pressing device is arranged in the groove and the through hole; the bottom part of the pressing device and the tail end of the clamping piece at the upper part of the spring clamp are in contact; and opening and closing of the spring clamp are achieved through the pressing device. By the insulating protection clamp, the cable core can be quickly and conveniently isolated; the operation is convenient; the insulativity is good; the safety is high; and the arrangement and recovery efficiency of safety measures is improved.

Description

Technical field [0001] The invention belongs to the field of cable protection devices, and particularly relates to a secondary cable core insulation protection clip. Background technique [0002] In the secondary debugging work of the circuit, the arrangement of some loop safety measures needs to temporarily remove and isolate the wire cores that affect other operating equipment from the terminal block. Because the insulation layer of these wire core ends has been stripped, the metal The exposed copper wires are very easy to be grounded or short-circuited by accidental touching, which may cause other operating equipment to malfunction. At present, the commonly adopted method is to wrap the bare copper wire part with the core of the electric wire with insulating tape. However, the insulating tape is easy to fall off after being heated, leaving a safety hazard; when the debugging is completed and the safety measures are restored, the wound insulating tape needs to be wound one by o...

Problems solved by technology

[0002] In the secondary commissioning of the circuit, the layout of some circuit safety measures needs to temporarily remove and isolate the live wire cores that affect other operating equipment from the terminal block. Since the insulation layer of the ends of these live wire cores has been stripped, the metal The copper wire is exposed, and it is very easy to accidentally touch it to cause grounding or short circuit, which will cause misoperation of other operating equipment

At present, the commonly used method is to wrap the exposed copper wire part with the wire core with insulating tape. However, the insulating tape is easy to fall off after being heated, leaving a safety hazard; when the debugging is completed and the safety measures are restored, the wrapped insulating tape needs to be removed Untie, connect the removed wire core back to the original terminal according to the secondary safety measure ticket, and check that it is correct. The whole process is time-consuming and laborious, which greatly reduces the efficiency of restoring the safety measure arrangement
