Emergency power supply quick connection electric connector structure

Abstract

The invention provides an emergency power supply quick connection electric connector structure which comprises a shell and a contact pin arranged in the shell, and is characterized in that the shell is T-shaped and comprises a square fixing block and a cylindrical connecting block; one end of the contact pin is fixedly connected with the fixing block, the other end of the contact pin is arranged in the connecting block, and a cylindrical inserting space is formed by the contact pin and the connecting block. A threaded hole for realizing butt joint locking of a head seat is formed in the contact pin; the end, away from the fixing block, of the contact pin is sleeved with a contact pin guide cone, the contact pin guide cone is in a circular truncated cone shape, a hole allowing the contact pin to be inserted is formed in the middle of the contact pin guide cone, and a barb structure for achieving interference fit and disengagement prevention of the contact pin and the contact pin guide cone is arranged between the inner wall of the hole and the outer wall of the contact pin.

[0002] Power grid emergencies lead to abnormal operation of equipment, interruption of normal power supply, and inconvenience to social production and people's life

Rapid emergency power supply has become an indispensable part of emergency rescue. At present, metal wire noses are often used in domestic emergency power supply systems. Although the connection of metal wire noses is simple, the disadvantages outweigh the advantages.

[0003] When connecting with metal wire lugs, the screws and nuts need to be manually locked, and the locking time of a single bolt takes five to ten minutes; the actual application is affected by the operating environment and operating space, and the tightening time may be longer, if there are not enough wrenches The space will not be able to connect; the metal wire nose is exposed without protection, the operation safety is low, and personal safety is difficult to guarantee; after long-term use, the metal surface of the wire nose is oxidized, the resistance increases, and it is easy to heat up, reducing reliability

At the same time, it is not insulated or waterproof, and has poor environmental adaptability
