Problems solved by technology

Because it has no anti-loosening device, the vibration or shaking of the equipment will cause the wire to loosen or drop, so it will bring great hidden dangers and unsafety to users, and may cause certain harm to people or equipment. Damage, in practice, this structure leads to a high failure rate, causing great harm

Abstract

The invention discloses an anti-looseness device for jackscrew fastening of a wire in electrical equipment. The anti-looseness device is installed in a round cavity of a wire base and is located at a wire installing opening of the wire base, the anti-looseness device comprises a round sliding plate in sliding fit with the round cavity and claws hinged to the sliding plate, and three or more claws are uniformly distributed on the edge of the sliding plate. In practical operation, a driving rod stretching out of the wire base makes a driving mechanism act, and under the action of the driving mechanism, the three or more claws complete the opening action while stretching out of the wire base. After the installing end of the wire is grasped, the driving rod is rotated reversely, the driving mechanism is reset, and the three or more claws retract in the round cavity of the wire base while closing and wrapping the installing end of the wire.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to installation equipment for electric wires or cables. Background technique [0002] The purpose of all kinds of cable plugs, sockets, wire plugs, sockets, and power products that rely on top wires to fasten the leads on the market is to fasten the wires so that the joints of the cables or wires have strict safety and reliability. Its structure is to tighten the wire or cable on the conductive copper body or the wire seat by ordinary screws or top screws (neither cover screws). Because it has no anti-loosening device, the vibration or shaking of the equipment will cause the wire to loosen or drop, so it will bring great hidden dangers and unsafety to users, and may cause certain harm to people or equipment. Damage, in practice, this structure leads to a high failure rate, causing great harm. Contents of the invention [0003] The technical problem solved by the inven...
