[0029] The schematic diagram for using round plug 31 as shown in Figure 1 When the device end adopts circular interface, at this time, need to use round plug 31, make square plug 32 insert into the inner wall of square plug -in slot 101, and through plug limit component to the limitation of round plug 31, to avoid round plug 31 to enter the inside of square plug -in slot 101, when square plug 32 is inserted into the inside of square plug -in slot 101, and inner net spring structure 40 is clamped and fixed to four side surfaces of square plug 32, thereby fixing round plug 31, at this time, can be connected with the device end circular interface through round plug 31.
[0030] The schematic diagram of using the square plug 32 is shown in Figure 2 When the device end adopts a square interface, the square plug 32 needs to be used at this time, the circular plug 31 is inserted into the inner wall of the square plug-in slot 101, and the square plug 32 is limited by the plug limiting assembly to avoid the square plug 32 from entering the inside of the square plug-in slot 101. When the circular plug 31 is inserted into the inside of the square plug-in slot 101, the inner spring structure 40 clamps and fixes the circular plug 31, and at the same time fixes the square plug 32. At this time, the square plug 32 can be inserted into the inside of the square interface of the device end.
[0031] Through the above operation steps, the circular plug 31 or the square plug 32 can be selected according to the interface shape of the device end, so that the bidirectional plug assembly 30 can be connected with the circular and square device end interface for operation, thereby expanding the application range of the contact structure.
[0032] It should be noted that the diameter of the circular plug 31 is matched with the width of the square plug-in slot 101, and the width of the square plug 32 is matched with the width of the square plug-in slot 101, so that the circular plug 31 or the square plug 32 will not be positionally deviated after being inserted into the inside of the square plug-in slot 101, thereby ensuring the stability of the circular plug 31 or the square plug 32.
[0033] As shown in Figure 4 and Figure 5 The inner spring structure 40 includes a rectangular three-dimensional mounting frame 41, a plurality of arc-shaped spring sheets 42 are mounted in the four side surfaces of the three-dimensional mounting frame 41, and the other two side surfaces of the three-dimensional mounting frame 41 without the arc-shaped spring sheets 42 are in a relative state. A part of the arc-shaped spring sheets 42 is located inside the three-dimensional mounting frame 41.
[0034] When the circular plug 31 or the square plug 32 is plugged in, when the circular plug 31 or the square plug 32 is inserted into the inside of the square plug-in slot 101, the circular plug 31 or the square plug 32 first contacts the plurality of arc-shaped spring sheets 42, and as the circular plug 31 or the square plug 32 gradually inserts into the square plug-in slot 101, the plurality of arc-shaped spring sheets 42 are extruded and deformed. When the position of the circular plug 31 or the square plug 32 can no longer be moved, the circular plug 31 or the square plug 32 is clamped by the reaction force of the plurality of arc-shaped spring sheets 42, thereby clamping and fixing the circular plug 31 or the square plug 32, so that the position of the circular plug 31 or the square plug 32 is no longer moved, and the fixing operation of the circular plug 31 or the square plug 32 is more convenient, thereby facilitating the conversion of the circular plug 31 or the square plug 32.

The outer diameter of the limiting ring 33 is greater than the diameter of the circular plug 31.
[0036] During the process of inserting the circular plug 31 or the square plug 32 into the square insertion slot 101, when the limiting ring 33 is in contact with the end of the conductive main body 10, if the circular plug 31 is needed to be used, the square plug 32 cannot enter the interior of the square insertion slot 101 by the limiting ring 33, and if the square plug 32 is needed to be used, the circular plug 31 cannot enter the interior of the square insertion slot 101 by the limiting ring 33, so that the circular plug 31 or the square plug 32 can be exposed to the outside and better connected with the device end interface.

[0043] The end of the circular plug 31 away from the square plug 32 and the end of the square plug 32 away from the circular plug 31 are provided with plug transition fillets, which are used to ensure that the circular plug 31 and the square plug 32 are more smoothly plugged into the square plug groove and the inside of the equipment interface.
