Self-tightening type insulation cover for controlling cable core end

Abstract

The invention discloses a self-tightening type insulation cover for controlling a cable core end. The insulation cover comprises a base, an eccentric wheel and an upper cover, wherein the upper cover is integrally assembled together with the base and the eccentric wheel is arranged in the integrated part. On the basis of the characteristics of the eccentric wheel mechanism, when the cable core is inserted into the insulation cover, the inner eccentric wheel is forward rotated, a gap of a cable core channel is increased and the cable core can be easily inserted; when the cable core is pulled out, a friction force is generated between the cable core and the eccentric wheel, the eccentric gear is reversely rotated, the gap of the cable core channel is reduced, the cable core is more tightly compressed by the eccentric gear and the cable core is difficult to be pulled out, so that the cable core is effectively prevented from loosening.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an insulating cap at the end of a self-tightening control cable core. Background technique [0002] In industrial fields such as electrical control and power secondary systems, a large number of control cables of various specifications are used. In the new construction or reconstruction and expansion projects as well as the repair and maintenance of electrical equipment, the correct handling of a large number of exposed control cable cores will be encountered. In order to realize the protection of the wire core and the electrical insulation between the wire core and other wire cores and equipment, and to protect the exposed cable core from environmental factors, the exposed wire core ends are often wrapped with electrical insulating tape. This method is easily affected by the quality of the package, the aging of the insulating tape or the humid environment, conductive...

AI Technical Summary

Problems solved by technology

This method is easily affected by the quality of the package, the aging of the insulating tape or the humid environment, conductive liquid, etc., and it is easy to fall off under the action of an external force. It is difficult to achieve long-term reliable protection of the exposed core and long-term reliable electrical insulation between the core and the surrounding equipment.
