Protection device capable of detecting and repairing conductive contact

Abstract

The invention discloses a protection device capable of detecting and repairing a conductive contact. The protection device comprises a protection cover; a protection cavity is formed in the protectioncover; a contact electric wire is connected into the upper wall of the protection cavity in an up-and-down sliding manner; the upper end of the contact electric wire extends to the upper side of theprotection cover; a base electric wire of which the lower end extends to the lower side of the protection cover is fixedly arranged in the lower wall of the protection cavity; a conductive base is fixedly arranged on the upper end surface of the base electric wire; a connecting cavity with an upward opening is formed in the conductive base; a conductive contact is fixedly arranged on the lower endsurface of the contact electric wire; the conductive contact can enter the connecting cavity; whether the conductive contact works normally or not can be judged according to the current of a circuit,when the current is small, the contact and the base can be automatically separated, then polishing treatment is conducted, an oxide layer is obtained by removing the surface of the contact, and the conductive performance of the contact is recovered.

Description

technical field [0001] The invention relates to the technical field related to electric conduction, in particular to a protection device capable of detecting and repairing electric contacts. Background technique [0002] In production and life, it is often necessary to connect the circuit, usually using a pair of conductive contacts and the base to connect, but in the process of long-term use, the surface of the contacts is prone to oxidation, resulting in an increase in resistivity and a decrease in circuit current , which affects the normal operation of the equipment, and manual maintenance is more troublesome, and it is impossible to accurately confirm which contact has a problem, and there will be certain safety hazards. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention [0003] Technical problem: During the long-term use of the conductive contact, the surface is prone to oxidation, resulting in an in...
