[0027] Working Principle: During operation, the second terminal 202 at one end of the second housing 201 is inserted into the first terminal 102 in the first housing 101 for electrical connection. During this process, the second cover 401 enters the inner side of the first housing 101, causing the flange 402 to move to the inner side of the end groove 302, so that each positioning post 4031 at the end of the flange 402 is snapped into the corresponding positioning groove 303, thereby positioning; The user then pushes the outer frame 4066 toward the first housing 101. During this process, the second spring 40611 is compressed. When the outer frame 4066 moves to a position where the latching rod 40610 corresponds to the latching slot 4067, the latching rod 40610 moves downward under the elastic force of the second spring 40611, causing the latching rod 40610 to latch into the latching slot 4067, thereby fixing the position of the outer frame 4066. When the outer frame 4066 moves toward the first housing 101, the piston block 4053 is pushed toward the second air pipe 4051 by the piston push rod 4061, producing the following effects: When the piston block 4053 moves toward the second air pipe 4051, the sealing ring 4056 is elastic when the power is connected, so that the surface of the sealing ring 4056 is in close contact with the inner wall of the first housing 101. The piston block 4053 is located on the side of the connecting groove 4055 close to the second air pipe 4051, so that the piston block 4053 moves, and a negative pressure adsorption effect is generated between the negative pressure chamber 4054 and the first housing 101, thereby fixing the first housing 101 and the second housing 201 with negative pressure to prevent loosening. When the piston block 4053 moves toward the second air pipe 4051, the air in the air cavity 4052 is pushed into the inner cavity 4032, which generates pressure on the side of the piston plate 4034 away from the engaging groove 304, pushing the engaging block 4035 outward to engage in the engaging groove 304, further securing the engagement, improving the stability of the engagement, and preventing loosening. When the piston plate 4034 moves to the extreme position, the surface of the piston plate 4034 contacts the inner wall of the inner cavity 4032 close to the clamping groove 304. At this time, the second ventilation groove 4038 is connected to the first air pipe 4041, and the piston block 4053 continues to move, so that air can enter the expansion airbag 4042 through the first ventilation groove 4037, the second ventilation groove 4038 and the first air pipe 4041, so that the expansion airbag 4042 expands, and the outer conductive rubber strip 4044 moves toward the inner wall of the end groove 302 until the outer conductive rubber strip 4044 is in close contact with the inner wall of the end groove 302, and the conductive metal The metal mesh 4045 can be stretched and will not hinder the expansion of the inflatable airbag 4042. When the outer conductive rubber strip 4044 is tightly attached to the inner wall of the end groove 302, the first cover body 301 and the second cover body 401 are electrically connected through the outer conductive rubber strip 4044, the inner conductive rubber strip 4043 and the conductive metal mesh 4045, so that the first cover body 301 and the second cover body 401 are combined to form a complete shielding cover, thereby improving the shielding effect. The first cover body 301, the second cover body 401, the flange 402 and the positioning column 4031 in the first shielding cover 3 and the second shielding cover 4 are all made of aluminum alloy.
