Anti-compression air-tight seal aviation electric connector

Abstract

The present invention relates to an anti-compression air-tight seal aviation electric connector. The electric connector comprises a socket and a plug, the socket comprises a round base and a protective cover, the round base comprises a flange, a connecting sleeve and a thread bush which are connected to an integrated structure, the round base is internally provided with a first contact, the firstcontact comprises a guide sleeve and an inner sleeve which are connected to an integrated structure, a hole cover plate is arranged between the inner side of a first seal body and the guide sleeve, asecond seal body is arranged between a hole insulator and the inner wall of the thread bush, the plug is internally provided with a plurality of second contacts, the second contacts and the first contact are internally provided with wire spring jacks, the protective sleeve is internally provided with a limited pillar, the end portion of the limited pillar is arranged in the wire spring jack of thefirst contact, and a rubber mat is arranged between the external portion and the thread bush. The anti-compression air-tight seal aviation electric connector is convenient and rapid in operation andinstallation, good in compression resistance and seal insulation performances, and low and stable in contact resistance, can still remain high-reliability electric contact performances in a strong vibration impact environment, is small in insertion and extraction force and low in wearing, can be suitable for various field of working condition environments with high pressure, high vacuum and high gas tightness.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a pressure-resistant air-tight aviation electrical connector. Background technique [0002] The use of electrical connectors in aviation, aerospace, national defense and other military and civilian systems and weaponry is huge. Aviation electrical connectors are responsible for the power transmission of the control system and the control and transmission of signals. There are very strict requirements for quality and reliability. Electrical connectors must achieve good contact, reliable operation, and easy maintenance. Whether their operation is reliable or not directly affects the normal operation of aircraft circuits and involves the safety of the entire host. Therefore, RF connectors have always been towards Development in the direction of miniaturization, modularization, high frequency, high precision and high reliability. The electrical connectors in the prior art generally use a f...

Problems solved by technology

The electrical connectors in the prior art generally use a fixed-end female contact, namely a plug, and a free-end male contact, that is, a socket. The plug is fixed on the electrical component through a split square or a disc, which is inconvenient to install and has poor compressive performance. advanced defects

[0003] The electrical connector is composed of three basic units: the shell, the insulator, and the contact body. The existing aviation plug shell includes the shell of the socket plug, the connecting nut, and the tail attachment, which protect the internal parts and are used for the connection and separation of the socket. It protects the terminal of the wire and the contact body from damage and is used to fix the cable, but it lacks a limit. When there are more contact pairs, the size of the electrical connector will be larger, and it is easy to cause misoperation accidents such as touching the pins; aerial insertion insulators The cover plate keeps the pin socket at the set position, and electrically insulates each contact body and each contact body and the shell from each other, but it is installed with a split sealing cover, resulting in a decrease in insulation performance and environmental resistance; The traditional aviation plug connector also uses the leaf spring hole, that is, the socket of the closed cantilever beam and the protective sleeve as the contact body, which not only has high resistance, but also requires a large insertion force, and at the same time, there is electrical contact instability in a strong vibration environment and high wear and tear. , leading to short service life and potential safety hazards
