[0043] At the same time, it also includes a ground connection wire 4 and an elastic contact terminal 6, wherein the ground connection wire 4 is located in the warehouse body, and one end of the ground connection wire 4 is inserted into another hole 25 so that it is clamped between the lower edge of the hole 25 and the fixed spring piece 3, and a ground terminal piece 5 is provided at the other end of the ground connection wire 4.

[0045] This embodiment improves the fixing structure of the internal wires, the waterproof structure of the inlet and outlet wires, and the grounding structure, which are described in detail below.

[0046] 1. Fixed structure of internal wires:

[0047] The handle 1 is snapped into and installed in the housing 7. The protrusion of the handle 1 forms a rotation fulcrum with the groove of the housing 7, so that the handle 1 can rotate back and forth in the housing 7. The compression spring 2 and the fixed spring 3 are assembled in the groove of the housing 7, so that the fixed spring 3 is fixed in the housing 7 and cannot move, but the compression spring 2 can bend and deform in the housing; when the handle 1 is bent upward, the distal end of the handle 1 moves downward, causing the compression spring 2 to move downward. At this time, the hole 25 of the compression spring 2 extends out of the lower part of the fixed spring 3, and the hole 25 is opened; when the handle 1 is bent downward and reset, the distal end of the handle 1 is separated from the compression spring 2, causing the compression spring 2 to reset. At the same time, the hole 25 on the compression spring 2 retreats into the upper part of the fixed spring 3; when it is necessary to install a signal cable, the handle 1 is bent upward, and the distal end of the handle 1 moves downward, causing the compression spring 2 to move downward. The hole 25 is opened below the fixed spring piece 3. At this time, the conductive part of the signal cable is extended into the hole 25, and the handle 1 is bent down to reset the handle 1. The distal end of the handle 1 is separated from the compression spring 2, so that the compression spring 2 is reset. The compression spring 2 is reset under the action of the elastic force. At this time, the hole 25 of the compression spring 2 is upward, so that the cable is clamped between the lower edge of the hole 25 and the fixed spring piece 3. By selecting a compression spring 2 of appropriate thickness, the signal cable can be effectively compressed. In the same way, the conductive part of the signal cable at the other end connected to the fixed spring piece 3 can be connected and fixed, thereby realizing the connection and tightening of the signal cable. Similarly, all signal cables can be quickly tightened through the above structure.

[0048] 2. Waterproof structure of inlet and outlet lines:

[0049] Insert the cable of the device signal line 22 into the cable head nut 9, sealing ring 10, cable fixing head 11, sealing gasket 12, and aviation connector sealing shell 14 in sequence, then lift up the handle 1, extend the conductive part of the signal line into the hole 25, and break off the handle 1. At this time, the conductive part of the signal line is completely fixed in the terminal block, install the cable fixing head 11 and sealing gasket 12 into the holes on the aviation connector sealing shell 14, and tighten the fixing nut 13, then insert the sealing ring 10 into the inner hole of the cable fixing head 11, and tighten the cable head nut 9 to complete the installation of the aviation connector sealing shell 14; insert the sealing rubber sleeve 18 into the aviation connector fixing seat 8, and push the aviation connector sealing shell 14 parts at both ends into the sealing rubber sleeve 18, buckle the buckle 17 into the aviation connector buckle locking column 15 to complete the aviation connector installation;

[0050] Install the installed aviation connector part on the instrument fixed metal plate 19. At this time, the elastic contact terminal 6 of the aviation connector is in close contact with the instrument fixed metal plate 19, and the sealing rubber ring 21 at the bottom of the aviation connector is in close contact with the instrument fixed metal plate 19, which plays a good waterproof role.

[0051] 3. Grounding structure:

[0052] The bottom of the aviation connector is provided with an elastic contact terminal 6. The upper portion of the housing of the elastic contact terminal 6 is provided with threads, which can be fixed to the ground terminal piece 5 of the ground connection line 4. At the same time, the lower portion of the housing of the elastic contact terminal 6 is provided with a cavity, inside which is a spring 28 and a copper thimble 27. The copper thimble 27 protrudes from the bottom of the aviation connector fixing base 8, allowing the copper thimble 27 to float up and down while providing good electrical conductivity. The copper thimble 27 is also provided with a sealing ring groove 29 and a sealing rubber ring 21 (which can be an O-ring) on ​​the periphery. When the aviation connector fixing base 8 is installed, when the aviation connector fixing screw 20 is locked and fixed with the instrument fixing metal plate 19, the copper thimble 27 is in close contact with the instrument fixing metal plate 19. At the same time, the sealing rubber ring 21 deforms under the action of the tightening force to form an interference fit, which can effectively prevent rainwater and water vapor from entering the copper thimble 27, thereby preventing the copper thimble 27 from rusting. In this process, reliable grounding can be achieved by simply fixing the aviation connector to the metal housing of the instrument, effectively reducing installation steps, and using it is simple, convenient, and reliable.
