[embodiment]
See also Fig. 1 to Fig. 4, the utility model provides a kind of three-electrode power plug, and it comprises a pin device 1 and a plug cover box 5 that is installed on this pin device 1.
This pin device 1 comprises a terminal block 111, and this terminal block 111 is isosceles triangle, which is provided with an earth pin 12, live wire pin 14, a zero line pin 16, is located at its three corners respectively.This terminal block 11 connects a power line 3, this power line 3 comprises a ground wire separated time 32, a live wire separated time 34, a zero line separated time 36, be connected respectively to this earth pin 12, live wire pin 14, zero line pin 16, extend in the opposite direction after this live wire separated time 34 and zero line separated time 36 are told from this power line 3 and be connected respectively on live wire pin 14, the zero line pin 16.Respectively offer a jack 18 on the dual-side of this terminal block 11.
This plug cover box 5 is that the plastic material of insulation is made, and it comprises a pair of cover plate 52 that should terminal block 11, and the outer rim place of this cover plate 52 vertically extends two wall extensions 54 that surround three pins (12,14,16) of these terminal blocks 11 to a side.The outer rim place that is arranged at this cover plate 52 that this two wall extensions 54 are symmetrical.This wall extension 54 comprises that a side prolongs wall 56 and one and prolong wall 58 with end that it intersects.
On this cover plate 52 to should live wire separated time 34 and zero line separated time 36 each extend downward vertically and be provided with a demarcation strip 60.These two demarcation strips 60 are connected to two sides and prolong wall 56, and respectively and this two end prolong between the wall 58 and to form a breach 62 that passes through for live wire separated time 34 and zero line separated time 36.This live wire separated time 34 and zero line separated time 36 are limited in this corresponding side respectively and prolong wall 56, the end and prolong between wall 58 and the demarcation strip 60.Because demarcation strip 60 insulate, they can not be contacted so realized live wire separated time 34 opened with zero line separated time 36 physical barrier.
Prolong at the bottom of two of these two wall extensions 54 and offer the breach 64 that this power line 3 of a confession passes through between the wall 58.The centre that the side of each wall extension 54 is prolonged wall 56 offers a breach 66, and the cover plate 52 at these breach 66 places is provided with a vertical extent and gets clasp 68.These two clasps, 68 correspondences are snapped in two jacks 18 of this terminal block 11 this plug cover box 5 are fixedlyed connected with this pin device 1.
