The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0039] Specifically, the difference of the automatic battery connector plug-in device provided in the second embodiment of the present application is that, in the automatic battery connector plug-in device, one side of the support mounting plate 7 is connected to the universal ball 6, and the universal ball 6 can drive the plug fixing mechanism mounting plate 5 to perform floating adjustment.

[0040] A spring clamping nut 12 is arranged on one side of the support mounting plate three, and a locking nut 13 is arranged on one side of the spring clamping nut 12.

[0046] The working principle of the automatic battery connector plugging device provided by the utility model is as follows:

[0047] Initial state: the fixed conical surface 10 is in a fitted state, at this time, the plugs fixed on the upper clamping block 1, the lower clamping block 2, the left clamping block 3 and the right clamping block 4 are at the origin position; during the Z-axis insertion process of the plug, due to the error in the position of the plug on the other side, the plug on this plug fixing mechanism will be subjected to the Z-axis direction extrusion force, at this time, the plug fixing mechanism that fixes the plug drives the plug fixing mechanism mounting plate 5 and the universal ball 6 to move backward as a whole, the fixing spring 11 is compressed, and the fitted fixed conical surface 10 is separated; at this time, the floating shaft 16 will form a floating gap 17 with the circular holes on the support mounting plate 1 7 and the support mounting plate 3 9, and the floating gap 17 is the floating gap in the XY direction. Momentum, at this time there is an angular float around the Z axis in the XY plane, and the floating amount here is designed as XY: ±2mm, and the rotation angle is: ±1.5°; when the Z axis direction is compressed to the point where the universal ball 6 fits on the support mounting plate 7, the floating in the Z axis direction ends, and at this time, continuing to push the plug in the Z axis direction can provide a greater insertion force; after this insertion is completed, the process of pulling out the plug is carried out along the Z axis direction, and the compressed fixed spring 11 extends out. After the plug is pulled out, the floating shaft 16 is restored to the fixed conical surface 10 that fits the conical surface again. At this time, the plug fixed on the clamping block 1 on the plug, the clamping block 2 on the bottom of the plug, the clamping block 3 on the left side of the plug, and the clamping block 4 on the right side of the plug return to the original position, waiting for the next insertion.
