the plug base body 10 is provided with a second power supply cable through hole 10B; the second power cable penetration hole 10B is adjacent to the pogo pin circuit board 13.

(III) connector base unit

The connector base unit comprises a connector base body 15 and a top bead limiting mechanism 16; the connector base body 15 has a groove matching the shape of the plug housing 10; the two sides of the groove are respectively and symmetrically provided with a bead-pushing limiting mechanism 16, as shown in fig. 25, which is a structure diagram of the connector base unit; when the plug base 10 is inserted into the groove, the ball-pushing limiting mechanism 16 locks the plug base 10, so as to fix the plug base 10 and the connector base body 15.

The invention also provides an operation method of the manual quick-release type spring pin connector, which comprises the following steps:

step 1, referring to fig. 26, a magnetic suspension active vibration isolation device mainly comprises a vibration isolation object and a vibration isolation device; fixedly connecting the vibration isolation device with the connector base unit, and fixedly connecting the socket unit with a vibration isolation object;

step 2, when the socket unit and the plug unit are in a separated state, the plug unit is pressed in the groove of the connector base unit, and the plug unit is limited through the bead-ejecting limiting mechanism 16, so that the degree of freedom of the plug unit is restrained;

and 3, when the socket unit and the plug unit are required to be in a connection state, operating in the following way:

step 3.1, manually and vertically pressing the rotary plectrum 8 of the socket unit to enable an end claw 8D of the rotary plectrum 8 to penetrate through an X-direction through hole 11A of the plug guide sleeve 11 and further insert the rotary plectrum into the plug guide sleeve 11 of the plug unit; then, the rotating plectrum 8 rotates clockwise by 90 degrees, and the end claw 8D of the rotating plectrum 8 is clamped into the Y-direction through hole 11B of the plug guide sleeve 11, so that the end claw 8D of the rotating plectrum 8 stably hooks the plug guide sleeve 11;

3.2, vertically pulling up the rotating plectrum 8, and when the rotating plectrum 8 moves upwards, driving the whole plug unit to overcome the limiting action of the bead-ejecting limiting mechanism 16 through the plug guide sleeve 11 to move upwards so as to separate the plug unit from the connector base unit;

when the rotating plectrum 8 drives the plug unit to enter the inner cavity of the socket base 1, the plug unit is enabled to continuously move upwards under the action of the restoring force of the compression spring 7, the spring pins 12 at the four corners of the plug unit penetrate through the jacks 2A at the four corners of the socket base 2 and are further contacted with the touch pad circuit board 3, and the spring pins 12 are continuously compressed along with the further upward movement of the plug unit, so that the spring pins 12 are tightly contacted with the touch pad circuit board 3; the spring pins 12 are electrically connected with the spring pin circuit board 13, so that the contact panel circuit board 3 of the socket unit is electrically connected with the spring pin circuit board 13 of the plug unit through the spring pins 12;

in the process that the plug unit moves upwards and is electrically connected with the socket unit, on one hand, the height of the socket outer guide sleeve 9 limits the upward movement distance of the rotary dial 8, and on the other hand, an end claw limiting groove formed at the lower part of the socket inner guide sleeve 4 limits the upward movement distance of the rotary dial 8, so that the rotary dial 8 is finally reset at a specific position, and the plug unit and the socket unit are kept in a connection state;

step 4, when the socket unit and the plug unit need to be changed from the connection state to the separation state, the following operation is carried out:

step 4.1, manually pressing the rotary plectrum 8 to drive the plug unit to move towards the connector base unit, so that the plug unit is separated from the socket unit; thereby leading the spring pin 12 to be not contacted with the contact disc circuit board 3 any more and leading the power supply circuit to be disconnected;

the plug unit is pressed into the groove of the connector base unit under the driving of the rotary plectrum 8, and the freedom degree of the plug unit is restrained under the limiting action of the bead-ejecting limiting mechanism 16; then, the rotating plectrum 8 is rotated to enable the rotating plectrum 8 to rotate 90 degrees anticlockwise, so that the end claw 8D of the rotating plectrum 8 rotates to the inner cavity of the plug guide sleeve 11 and is separated from the Y-direction through hole 11B; simultaneously, the rotating plectrum 8 is lifted upwards, so that an end claw 8D of the rotating plectrum 8 passes through the X-direction through hole 11A of the plug guide sleeve 11, the rotating plectrum 8 is separated from the plug unit, and the plug unit and the socket unit are completely separated;

when the rotary plectrum 8 moves upwards, on one hand, the height of the outer guide sleeve 9 of the socket limits the upward movement distance of the rotary plectrum 8, and on the other hand, an end claw limiting groove formed at the lower part of the inner guide sleeve 4 of the socket limits the upward movement distance of the rotary plectrum 8, so that the rotary plectrum 8 is finally reset at a specific position.

The manual quick-dismantling spring pin connector and the operation method thereof provided by the invention have the following advantages:

(1) the manual quick-dismantling spring pin connector provided by the invention has the advantages of simple structure, convenience in processing, small size and weight, small occupied resource, safe and reliable motion of contact and separation actions of the connector, convenience and flexibility in installation and use, capability of solving the problem of quick disconnection and connection of a power supply cable between a vibration isolation object and a micro-gravity active vibration isolation device and convenience in convenient disassembly, assembly, maintenance and replacement of the vibration isolation object.

(2) This patent is solved and is supplied power cable switch-on and separation problem between space microgravity initiative vibration isolation technique vibration isolation object and the vibration isolation device, can let its work to the vibration isolation object power supply after the connector switch-on, and the connector separation back has not had the physics connection environment between vibration isolation object and the vibration isolation device, conveniently carries out the dismantlement maintenance of vibration isolation object and vibration isolation device.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and improvements can be made without departing from the principle of the present invention, and such modifications and improvements should also be considered within the scope of the present invention.
