Waterproof short-circuit-proof three-layer sealing separation electric connector

Abstract

The invention relates to a waterproof short-circuit-proof three-layer sealing separation electric connector. A three-layer sealing structure is adopted; and sealing separation indexes are realized between an insulator, a contact element and a shell by pouring polyurethane glue; an underwater waterproof structure is adopted, so that sealing measures are adopted for a water leakage channel to achieve waterproof and short-circuit-proof functions; an underwater air pressure balance structure is added, so that the electric connector can meet an air pressure sealing requirement and can also meet anunderwater short-circuit prevention requirement; an insertion in-place state judging structure is adopted, so that an insertion in-place state can be judged through a method of identifying an insertion in-place state marking line.

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 ...

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
