[0022] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0023] A gas-tight micro-rectangular adapter, comprising a socket assembly 1, a plug assembly 2 and a guide post assembly 3. The plug assembly 2 is arranged on the left side of the socket assembly 1, and two guide post assemblies 3 are arranged on the left side of the socket assembly 1; the socket assembly 1 includes a socket housing 101 and a sealing groove 102. Sealing grooves 102 are arranged on both the left and right sides of the socket housing 101, and sealing frames 103 are fixedly connected to the inner sides of the sealing grooves 102.

The sealing block 107 is fixedly connected to the pin bodies 105. A first insulator 108 is fixedly connected to the left side of the sealing block 107. A first potting compound 109 is fixedly connected to the left side of the first insulator 108. An airtight block 110 is fixedly connected to the left side of the first potting compound 109. The plug assembly 2 includes a plug housing 21 and a power transmission line 22. A plurality of power transmission lines 22 are arranged inside the plug housing 21.

Guide holes 28 are arranged on both the front half and the rear half of the plug housing 21. The guide post assembly 3 includes a guide post body 31 and an adjustment cavity 32. Two guide post bodies 31 are fixedly connected to the left side of the socket housing 101. Adjustment cavities 32 are arranged inside the guide post bodies 31. Two limiting grooves 33 are arranged on both the left and right sides of the adjustment cavity 32. A pair of locking blocks 34 are slidably connected inside the adjustment cavity 32 of the guide post body 31. Limiting blocks 35 are fixedly connected to both the left and right sides of the locking blocks 34. The guide post body 31 is slidably connected through the limiting grooves 33 and the limiting blocks 35. A plurality of compression springs 36 are fixedly connected between each pair of locking blocks 34.

[0024] Furthermore, bolt connection holes are arranged on both the front half and the rear half of the socket housing 101. The sealing frames 103 are all rubber rectangular frames. There is a gap between the outer sides of the sealing frames 103 and the socket housing 101. The back sides of the two sealing frames 103 protrude beyond the left and right sides of the socket housing 101. The sealing frames 103 in the sealing grooves 102 can improve the sealing performance between the socket housing 101 and the equipment housing.

[0025] Further, the first insulator 108, the first potting compound 109, and the airtight block 110 are all fixedly connected to the socket housing 101, and the first insulator 108, the first potting compound 109, and the airtight block 110 are all fixedly connected to the pin body 105. The second potting compound 26 and the third insulator 27 are both fixedly connected to the plug housing 21, and the second potting compound 26 and the third insulator 27 are both fixedly connected to the electrical contact post 23. Through the sealing block 107, the first insulator 108, and the first potting compound 109, the pin body 105 and the pin head 106 can be stably fixed. Through the second insulator 25, the second potting compound 26, and the third insulator 27, the electrical contact post 23 can be stably fixed.

[0026] Further, the left half of the airtight block 110 is located inside the plug housing 21. The left side of the airtight block 110 is in contact with the second potting compound 26, and the inner side of the airtight block 110 is in contact with the third insulator 27. The number of power transmission lines 22 is equal to that of the pin bodies 105. The pin heads 106 are all located inside the split groove holes 24. Multiple pin heads 106 can be synchronously inserted into the corresponding split groove holes 24. At this time, the pin body 105, the pin head 106, the electrical contact post 23, and the power transmission line 22 are electrically connected in sequence.

[0027] Further, the guide post bodies 31 all pass through the guide holes 28. The upper and lower sides of the adjustment cavity 32 are through. The right sides of the two pairs of locking blocks 34 are both in contact with the plug housing 21. The plug housing 21 can be restricted by the locking blocks 34, so that the plug housing 21 and the socket housing 101 are automatically locked.

[0028] Workflow: Check whether all components are intact before use. The socket assembly 1 and the plug assembly 2 of the device can be assembled by plugging and unplugging. When using the device, first electrically connect the pin body 105 of the socket assembly 1 to the device body, electrically connect the power transmission line 22 of the plug assembly 2 to the transfer line, and fix the socket housing 101 to the device housing through the connecting bolts 104. The socket housing 101 can be installed in front of the board or behind the board. The sealing frame 103 in the sealing groove 102 can improve the sealing between the socket housing 101 and the device housing. The pin body 105 can be sealed by the sealing block 107, the first insulator 108, and the first potting glue 109. The second insulator 25, the second potting glue 26 and the third insulator 27 can stably fix the connecting post 23. The user aligns the socket housing 101 and the plug housing 21, presses the two pairs of locking blocks 34, and makes the locking blocks 34 completely enter the adjustment cavity 32. At this time, the limit block 35 moves in the limit groove 33, and the compression spring 36 is compressed. Then, the guide column body 31 is inserted into the guide hole 28. The plug housing 21 is guided by the guide column body 31, and multiple pins 106 can be accurately and synchronously inserted into the corresponding split slots 24. At this time, the pin body 105, the pin head 106, the connecting post 23, and the transmission line 22 are arranged in a fixed manner. The electrical connection is made for the second time. At the same time, the airtight block 110 is inserted into the plug housing 21. The elastic airtight block 110 cooperates with the third insulator 27 to ensure the airtightness of the connection between the pin head 106 and the second potting glue 26. When the socket housing 101 and the plug housing 21 are tightly fitted, the plug housing 21 no longer restricts the locking block 34. The elastic force of the compression spring 36 can make the locking block 34 partially protrude from the adjustment cavity 32. The limiting groove 33 can limit the limiting block 35 to prevent the locking block 34 from escaping from the adjustment cavity 32. At this time, the right side of the locking block 34 is in contact with the plug housing 21, and the locking block 34 can prevent the plug housing 21 from being detached from the adjustment cavity 32. By moving the guide column body 31 left and right, the plug assembly 2 and the guide column assembly 3 can be automatically locked; the device can seal the socket housing 101 and the equipment housing through the sealing frame 103, and the airtight block 110 cooperates with the third insulator 27 to perform airtight sealing, so as to ensure the airtightness of the connection between the pin needle 106 and the second potting glue 26. At the same time, the paired locking blocks 34 are moved away from each other by the compression spring 36, and the locking blocks 34 are limited by the limit block 35. The plug housing 21 is restricted by the locking block 34, so that the plug housing 21 and the socket housing 101 are automatically locked. The device has good airtightness and connection stability, stronger product performance and wider application range.
