Embodiment Construction

[0040] The following will combine Figure 1 to Figure 18 The electric connector device which is easy to be disassembled on rail of the present invention is further described in detail.

[0041] The preferred embodiment of the present invention takes the J599 electrical connector as an example to describe in detail the electrical connector device that is easy to be disassembled on rail in the present invention. The present invention is also applicable to other rotary electrical connectors.

[0042] figure 1 A schematic diagram of the J599 electrical connector plug is shown; figure 2 A schematic diagram of the J599 electrical connector receptacle is shown.

[0043] see figure 1 and figure 2, The J599 electrical connector includes a plug 1 and a socket 2, and the plug 1 and the socket 2 are threadedly connected. Specifically, the shell 1-1 of the plug 1 has an internal thread, the socket 2 has an external thread 2-1, and the number of thread engagement circles is 1, and t...

Abstract

The electrical connector device that is easy to be disassembled on the rail of the present invention includes an electrical connector; the electrical connector includes a plug and a socket, and the socket is fixedly installed on the aircraft as a part that cannot be disassembled on the rail; the ratchet and ratchet mechanism is used as a plug accessory and The plug is integrated as an on-rail detachable part; the ratchet and ratchet mechanism swings back and forth around the axis of the electrical connector to unscrew the plug out of the socket. The electrical connector device that is easy to disassemble on rail of the present invention integrates the ratchet mechanism with the plug of the electrical connector, and converts the one-way rotation movement of the electrical connector separation and disassembly into a small-scale reciprocating swing motion, so that astronauts can use it easily. Hand tool operation reduces the need for maintenance tools and astronaut operating capabilities.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector device that is easy to be disassembled on rails. Background technique [0002] Maintainability, as one of the important ways to improve the working life of space mechanism, has been widely adopted in the design of space mechanism, that is, maintainability design. [0003] Large-scale space agencies are composed of many small-scale agencies, and quite a few of these small-scale agencies are single-point links. Whether this part of the agency can work normally will directly affect the life of the entire large-scale space agency. Therefore, in the design of the mechanism, fully consider the maintainability design, and adopt the on-orbit replaceable design for some components, that is, when a failure of a component is detected, the astronauts can replace it in the out-of-orbit cabin. [0004] In terms of functional design, limited by the current level of research an...
