[0024] The working principle of the above technical solution: in actual use, in the process of inserting the plug of the electric appliance, the live plug blade and the zero plug blade of the plug are inserted into adjacent two slots 2 respectively, after entering slot 2, after contact sleeve 3, it will be connected with the pre-connected live line and zero line of the city power in slot 2, so as to obtain power supply; when the plug is pulled out, the plug blade is separated from the city power line, and the plug blade is still in contact with the contact sleeve 3, under the action of fitting mechanism, contact sleeve 3 is connected with discharging mechanism, so that discharging mechanism consumes the residual electricity on the plug;

[0025] The beneficial effects of the above technical solution: through the above technical solution, by setting discharging mechanism in shell 1, residual electricity on the plug is consumed when the electric appliance is pulled out, which avoids setting discharging circuit on the electric appliance and reduces the use cost of the electric appliance.

[0026] In one embodiment, plug-in mechanism further includes: raised plate 4, one end of raised plate 4 is deeply into contact sleeve 3, the other end of raised plate 4 is inserted into discharging cavity 5;

[0027] The working principle and beneficial effects of the above technical solution: one end of raised plate 4 is deeply into contact sleeve 3, so that the plug blade rubs with raised plate 4, increases the difficulty of pulling out and inserting, and increases the discharging processing time of discharging mechanism.

[0028] In one embodiment, fitting mechanism includes:

[0029] Limiting plate 6, spring 7, sliding plate 8, trigger rod 9 and clamping plate 10, adjacent two limiting plates 6 are parallelly arranged at the bottom end of the inner wall of discharging cavity 5, the two ends of sliding plate 8 are respectively connected with adjacent two limiting plates 6, spring 7 is arranged between adjacent two limiting plates 6, one end of trigger rod 9 is connected with the top end of sliding plate 8, the other end of trigger rod 9 passes through shell 1, clamping plate 10 is sleeved on trigger rod 9, and clamping plate 10 is located in discharging cavity 5;

[0030] The limiting plate 6 is an arc-shaped plate;

[0031] The discharging mechanism comprises a first connecting wire 14, a second connecting wire 15, a discharger, a first fitting piece 12 and a second fitting piece 13, the second fitting piece 13 is arranged on the inner side wall of the discharging cavity 5, the two ends of the discharger are connected with the second fitting piece 13 and one of the contact sleeves 3 through the second connecting wire 15, the first fitting piece 12 is arranged on the trigger rod 9, the first fitting piece 12 is located in the discharging cavity 5, and the first fitting piece 12 is connected with the other contact sleeve 3 through the first connecting wire;
