The upper ratchet and the lower ratchet tend to fold under the action of the torsion spring 7. When the upper ratchet is in contact with the bidirectional ratchet 5 and the lower ratchet is separated from the bidirectional ratchet 5, the upper ratchet and the bidirectional ratchet 5 form an installation mode, and the ratchet drives the bidirectional ratchet 5 to rotate in the direction of installing the electric connector.

The thimble pin 12 sequentially passes through the thimble pin 12 holes at the bottom of the thimble 11 and the lower shell 4, one end of the thimble pin 12 is penetrated with a chute pin 13, and the chute pin 13 can slide in a chute of the chute block 14; the chute block 14 slides up and down to drive the chute pin 13 to slide horizontally, and the chute pin 13 moves horizontally to drive the thimble pin 12 to slide in the lower shell 4 and the thimble 11 hole of the thimble 11.
The external interface 15 is installed on the lower housing 4, the external interface 15 drives the lower housing 4 and the upper housing to rotate circumferentially around the rotation shaft of the electrical connector plug, and further drives the internally installed ratchet loop bar 10 to rotate axially around the rotation shaft of the electrical connector plug, at this time, the fixed ratchet on the ratchet loop bar 10 still keeps the relative position with the ratchet loop bar 10 still, and the free ratchet on the ratchet loop bar 10 is attached to the corresponding ratchet of the bidirectional ratchet 5 under the elastic force of the torsion spring 7 and can rotate around the ratchet loop bar 10, so as to form a pair of ratchet mechanisms, which is one of an installation mode ratchet mechanism and a disassembly mode ratchet mechanism, namely, the disassembly and assembly of the electrical connector are realized by the rotation of the external interface 15 through the reciprocating swing.
The working principle is as follows:
during ground installation and on-track installation, the chute block 14 is located at the lower limit of movement, the chute pin 13 is located at the rightmost end of the chute block 14, the thimble pin 12 is inserted into the thimble 11 hole of the thimble 11, at this time, the lower ratchet switching pin of the ratchet switching frame 18 is inserted into the ratchet switching hole of the lower ratchet, the lower ratchet is fixed and is separated from contact with the lower ratchet of the bidirectional ratchet 5, and the upper ratchet is in a free state and is in contact with the upper ratchet of the bidirectional ratchet 5, so that the function of the normal ratchet is exerted. At the moment, the ratchet wheel ratchet state is an electric connector installation state, and the electric connector plug can be installed on the electric connector socket by swinging the external interface 15 in the reciprocating circumferential direction. In the installation process, as the electric connector plug gradually approaches to the electric connector socket, the chute pin 13 is in contact with the upper end face of the installation support of the electric connector socket and gradually moves upwards, and when the electric connector plug is to be installed in place, the chute quickly drives the chute pin 13, so that the thimble pin 12 is driven to completely withdraw from the thimble pin 12 hole of the thimble 11. At this time, the thimble 11 moves upward under the action of the spring force of the spring 16 of the thimble 11, the ratchet switching frame 18 moves upward along with the thimble 11, the lower ratchet switching pin of the ratchet switching frame 18 is separated from the ratchet switching hole of the lower ratchet, the upper ratchet switching pin of the ratchet switching frame 18 is inserted into the ratchet switching hole of the upper ratchet, the upper ratchet is fixed and is separated from contact with the upper ratchet of the bidirectional ratchet 5, the lower ratchet returns to a free state and is in contact with the lower ratchet of the bidirectional ratchet 5, at this time, the thimble 11 obviously protrudes from the upper end surface of the upper shell, a spaceman can directly observe the thimble and stop rotating the external interface 15, the on-rail installation of the electric connector is completed, and the ratchet mechanism of the bidirectional ratchet 5 is automatically switched to a dismounting mode.
When the ground is disassembled and the electric connector is disassembled on the track, because the two-way ratchet wheel 5 mechanism is automatically switched into the disassembling mode during the assembling, a astronaut only needs to rotate the external interface 15 pieces in a reciprocating way, and then the plug of the electric connector can gradually withdraw from the socket of the electric connector, so that the electric connector can be disassembled on the track.
