[0023] A support plate 4 is fixedly installed below the connecting terminal 6, a fixed plate 502 is arranged on the upper surface of the support plate 4, and two sliders 504 are arranged between the two fixed plates 502, and a second elastic member 505 is arranged between each of the sliders 504 and the fixed plate 502, and a mounting plate 509 with a connecting seat 508 fixedly installed at the bottom is arranged between the support plate 4 and the connecting terminal 6, and the connecting seat 508 and the two sliders 504 are movably connected through a rotating rod 507;

[0024] When the internal connector is vibrated by external force, the mounting plate vibrates, and the slider moves along the fixed rod through the movement of the rotating rod, and the moving block moves in the slide groove. The slider can be unloaded by the second elastic member between the slider and the fixed plate, thereby achieving buffering. When the terminal block vibrates with the mounting plate, the top plate is always tightly clamped with the terminal block through the first elastic member to prevent the terminal block from loosening.

[0025] A fixing rod 503 is installed between the two fixing plates 502 , and the two sliding blocks 504 are sleeved on the fixing rod 503 ; there are two fixing rods 503 , and the two fixing rods 503 are arranged in parallel and at intervals.

[0026] The second elastic member 505 is located at opposite sides of the two sliding blocks 504 , and the second elastic member 505 is sleeved on the outer wall of the fixing rod 503 .

[0027] A slide groove 501 is provided on the upper surface of the support plate 4 and between the two fixing plates 502 , and a moving block 506 slidably connected to the slide groove 501 is installed at the bottom of the sliding block 504 .

[0037] The working principle is:

[0038] When in use, the wire tube can be used to connect to the wiring terminals inside the box, and the wiring terminals are clamped and fixed by the top plate and the mounting plate. When the internal connector is vibrated by external force, the mounting plate vibrates, and the slider moves along the fixed rod through the movement of the rotating rod, and the moving block moves in the slide groove. The second elastic member between the slider and the fixed plate can unload the force on the slider, thereby achieving buffering. When the wiring terminals vibrate with the mounting plate, the top plate is always clamped and fitted with the wiring terminals through the first elastic member to prevent the wiring terminals from loosening.

[0039] When using shore-based power connection equipment, the connection terminal is pressed and fixed on the mounting plate through the top plate, and when the mounting plate moves downward, it pushes the two sliders to move away from each other and compress the second elastic member, thereby buffering the position change of the connection terminal and avoiding loose connection of the connection terminal, thereby ensuring the reliability of the connection terminal.
