Problems solved by technology

[0003] In the prior art, the current separated electrical connectors either only have a sealing function, or only have an underwater waterproof function. For the separated electrical connectors that are air-tight in a specific environment, there is no waterproof and waterproof connector that can be used in an underwater environment. Therefore, there is an urgent need for an electrical connector that satisfies the air pressure seal index and can also be used underwater to achieve watertightness of the individual head seat, waterproof and short-circuit proof in the splashing water environment during the separation process of the head seat, and the plug and socket of the head seat. Determinable new use environment requirements in place

Abstract

A waterproof and short-circuit-proof three-layer sealed separation electrical connector, which adopts a three-layer sealed structure, and uses polyurethane glue to seal between the insulator, the contact piece, and the shell to realize the sealing and separation index; it adopts an underwater waterproof structure setting, and the water leakage channel Sealing measures are adopted to realize the function of waterproof and short-circuit prevention; an underwater air pressure balance structure is adopted to make the electrical connector not only meet the requirements of air pressure sealing, but also realize the requirements of underwater anti-short circuit; the use of setting plug-in and in-place discrimination structure realizes the identification of plug-in and connection The method of marking line in place is used to judge whether it is inserted and in place.

Description

technical field [0001] The invention belongs to the technical field of aerospace electrical connectors, and relates to an inter-stage separation electrical connector, in particular to a short-circuit-proof three-layer separation electrical connector used in air pressure sealing and underwater environments. Background technique [0002] Separation and fall-off electrical connectors are widely used in the field of aerospace where electrical connections are required. As one of them, the hermetically separated electrical connector has also been greatly developed. At present, with the continuous complexity of the use environment, a certain air-tight electrical connector must not only meet the air-tightness index, but also need to be able to be used underwater, realize the watertightness of individual plugs and sockets, and prevent splashing during the separation process of the head and seat. In the water environment, the requirements of the new use environment of waterproof and ...
