Open circuit-resistant aviation socket

Abstract

The invention provides an open circuit-resistant aviation socket, comprising a socket shell. The center of the socket shell is provided with a through hole in which a front cover and a rear cover thatare arranged at intervals are arranged in the through hole, a middle cover capable of sliding along the axial direction of the through hole is arranged between the front cover and the rear cover, a plurality of insertion needles are fixed on the rear cover, the middle cover is provided with a plurality of insertion needle holes, the needle heads of the insertion needles pass through the insertionneedle holes in the middle cover and the front cover and are positioned in the through hole, a reset spring is arranged between the middle cover and the rear cover, a surface, which faces the front cover, of the middle cover is provided with a push rod which passes through the front cover, and is further provided with a short circuit slot which is communicated with an insertion needle hole position for a short circuit insertion needle, a conductive short circuit component is paved at a slot bottom of the short circuit slot, an insulating cylinder is arranged at an orifice of the insertion needle hole in the slot bottom of the short circuit slot, and one end, which faces the front cover, of the insulating cylinder is successively provided with a copper flat gasket and a contact spring. Before insertion, the open circuit-resistant aviation socket can be used for performing short circuit on a certain insertion needle, and after the insertion, the short circuit insertion needle can be automatically switched off.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to an anti-open circuit aviation socket. Background technique [0002] In addition to meeting the general performance requirements, the electrical connector must meet the requirements of good contact, reliable operation, and convenient maintenance. Whether the electrical connector is reliable or not directly affects the normal operation of the aircraft circuit and involves the safety of the entire host. For this reason, the host circuit has very strict requirements on the quality and reliability of the electrical connector, and because of the high quality and reliability of the electrical connector, it is also widely used in military systems such as aviation, aerospace, and national defense. Commonly used classification methods for electrical connectors include shape, structure, and use. [0003] In the existing electrical connectors, the pins often do not interfere with each o...

Problems solved by technology

[0003] In the existing electrical connectors, the pins often do not interfere with each other before and after insertion, but in some occasions where the pins need to be short-circuited before the electrical connector is docked, take the anti-open circuit aviation plug as an example, its main purpose is It is used to protect the current transformer. When the secondary wiring of the curren
