Abstract
Description
Technical Field
[0001] The present invention relates to a lunar dust resistant connector, which is mainly used in lunar dust environments where it is suitable to perform plugging and unplugging operations while wearing pressure gloves. Background Art
[0002] Due to the moon's relatively low gravity, when astronauts conduct extravehicular activities (EVA) on the lunar surface, a large amount of floating lunar dust is stirred up by the lunar surface, depositing a layer of it on the surfaces of extravehicular electrical equipment. In this dusty environment, astronauts wearing pressure gloves and extravehicular suits are restricted in their movements, their perceptions are obstructed, their field of vision is narrowed, and their physical exertion is increased. These factors interfere with and weaken their physical and sensory abilities. To adapt to the dusty environment and compensate for the debilitating effects of astronauts' EVAs, connectors for extravehicular plugging and unplugging must be resistant to lunar dust, including dust protection, dust removal, and dust retention. They must also meet the ergonomic requirements of the lunar surface environment and the grip requirements of lunar suit gloves. They must possess blind insertion, prevent mis-insertion, prevent oblique insertion, have low insertion and extraction forces, and feature convenient and reliable locking. These connectors should be able to facilitate normal plugging and unplugging operations and power-on operations for astronauts wearing pressure suits and gloves in the dusty lunar surface environment. Summary of the Invention
[0003] The purpose of the present invention is to provide a lunar dust-resistant connector, which solves the technical problem of astronauts wearing pressure space suits and pressure gloves to perform plugging and unplugging operations in an environment filled with lunar dust.
[0004] The present invention relates to a moon dust-resistant connector, comprising two parts: a plug and a socket. The plug includes a dust cap, a plug housing, a hook wrench, a torsion spring, a rotating shaft, a socket, a dust rod, a spring, a socket insulator, a socket insulating cover, a dust ring, a dust filter, a handle, and a fixing rope. The socket includes a dust cover, a torsion spring, bracket 1, bracket 2, a push rod, a roller, a spring, a rotating shaft, a socket housing, a pin, an insulator, an insulating cover, a dust filter, a sealing gasket, and a cable cover.
[0005] The outer circle of the plug-in end is oblate, with a removable dust cap on the outside, and a fixing rope tied between the dust cap and the plug housing; a rotating shaft is fixed to the outer circle of the plug housing, and the rotating shaft crosses the single hook wrench. A torsion spring is arranged between the rotating shaft and the single hook wrench, and the two ends of the torsion spring are respectively fixed on the hook wrench and the rotating shaft 1, and dust rings are arranged on both sides of the hook wrench; the jack is fixed between the jack insulator and the jack insulating cover plate. The jack is a hollow structure with a built-in spring and dust rod, and a dust filter ring is arranged at the mouth of the jack; a handle is provided at the tail of the plug housing.
[0006] Bracket 1 and bracket 2 are fixed on the socket flange, the rotating shaft is fixed in the holes of bracket 1 and bracket 2, the dust cover, torsion spring and dust ring are fixed on the rotating shaft, the two ends of the torsion spring are respectively fixed on the dust cover and the rotating shaft, a sealing gasket is fixed on the dust cover, and the dust cover can rotate around the rotating shaft. A push rod, roller, spring and dust ring are arranged in bracket 1; a locking step is provided on the outer circle of the socket end face, the socket plug-in end is in the shape of an oblate cone hole, and a dust filter ring is provided at the entrance of the plug-in end; the pin is fixed between the pin insulator and the pin insulation cover plate; a cable cover is provided at the rear of the socket shell.
[0007] When the plug and socket begin to mate, first manually remove the plug dust cap, open the socket dust cover and flip it up to the locked position, insert the plug end into the socket tapered hole, and guide the plug shell along the socket tapered hole into the socket shell inner hole, while the pin presses against the socket dust rod. Then push the plug into the socket, and the pin pushes the dust rod together into the socket cavity, so that the pin and the socket engage. Continue to push the plug until the plug wrench hook locks the socket shell step. During this process, the plug presses the socket push rod to open the socket dust cover locking mechanism, allowing the socket dust cover to flip freely.
[0008] When the plug is separated from the socket, first press the plug hook wrench to disengage the hook wrench from the socket shell step, and then pull out the plug; the pin is simultaneously pulled out of the socket, the dust rod is pushed out from the inner cavity of the socket, and passes through the dust filter ring outside the socket mouth to seal the socket mouth; at the same time, the socket dust cover and its sealing gasket are buckled on the socket plug-in end; then manually buckle the plug dust cap on the plug plug-in end.
