At first consult shown in Fig. 1-3, have common power supply unit in the present embodiment, accommodate a printed circuit board (PCB) 2 in the inside of a shell 1, electric current from power supply is behind the circuit on this circuit board 2, flow to computer from output terminal 3, belong to prior art, so will not give unnecessary details.

Present embodiment also has prong mechanisms 4 and socket mechanism 5 two parts, and details are as follows respectively:

Shown in Fig. 2,3, prong mechanisms 4 comprises: a pair of pin 401a, 401b, it is to be molded on the fixed base frame 402 of an insulation (being made by plastic material).The front end of pin stretches out outside the fixed base frame, as inserting supply socket (marking) thereafter; And outside the also outstanding fixed base frame 402 in rear end, as two contact feets, 401 ' a, 401 ' b; And fixed base frame 402 is to be articulated on the bearing bracket stand of outer face of shell 1, in the time of can doing the rotation of 90 degree in stressed back, contact feet 401 ' a, 401 ' b can change the inside of shell 1 over to by through hole 101a, the 101b in 1 liang of corresponding position of shell, become state shown in the solid line among Fig. 2.

As shown in Figure 5 and Figure 6, on shell 1, sever a hyoplastron 102, only link together, and have elasticity in rear end and shell 1 over against the lower position of solid pedestal 402.In addition, as shown in Figure 6,, can engage,, can not rock arbitrarily in order to positioning and fixing pedestal 402 with the beading 1021 on hyoplastron 102 front ends above the fixed base frame 402 and on the left end face depression 403a, 403b being arranged respectively.

And for example shown in Fig. 7-9, as pin 401a, when 401b is in erectility, in U type folder 6a, the 6b that two contact feets, 401 ' a, 401 ' b link together the circuit that changes over to respectively with circuit board, leg clampings in two fens by U type folder 6a, 6b, and the free end contact of contact feet 401 ' a, 401 ' b is pressed in the U type and presss from both sides on the integrated shell fragment 6c, finishes electric contact the between contact feet and U type folder and shell fragment.On contact feet 401 ' a, 401 ' b, can establish through hole 60 ' a, 60 ' b again; And cause prominent some 602a, a 602a ' (602b, 602b ') when the clamping contact feet the contiguous free ends of two fens legs of U type folder 6a, 6b, and can stretch in the through hole 601a (601b), guarantee clamping stability more.

Shown in Fig. 1,10,11, socket mechanism 5 comprises: one is fixed on the socket 501 in shell 1 left side, with the prior art structure roughly the same, so explanation is omitted, become to be connected in series (as shown in Figure 2) but press from both sides via lead 8 and above-mentioned U type; An and over cap assembly 7.This over cap assembly 7 comprises: an end is articulated in the over cap 701 on the shell 1, forms a convex 702 on inner face, cooperates each other with the inlet profile of socket 501.Again on the shell at over cap 701 pivot end positions; also in the mode of identical above-mentioned formation hyoplastron 102; cutting is produced and is had elasticity hyoplastron 103 on shell 1, and forms a beading 1031 at its front end, can form a pairing with the depression 703 that is formed on the over cap 701.

When desire utilizes prong mechanisms 4 and electric power connecting right, at first pin 401a, the 401b that will be in state as shown in Figure 3 usually by the user from be attached at position on shell 1 end face rotate 90 spend shown in Fig. 2 solid line vertical on the state with shell 1.At this moment, contact feet 401 ' a, 401 ' b have changed in the shell 1 again, press from both sides 6a, 6b by the U type, and clamping, and compresses on the shell fragment 6c, and the beading 1021 of hyoplastron 102 front ends slips into depression 403b (as shown in Figure 6) and fixed answering on the fixed base frame 402.Subsequently, be about to pin 401a, 401b and insert the supply socket (not shown), source current promptly flows into circuit board 2 via U type folder 6a, 6b and shell fragment 6c, since output terminal 3 input computer (not shown).

Otherwise, when desire utilizes socket mechanism 5 as connecting the civil power place, promptly turn back to horizontality as Fig. 3 by the earlier true prong mechanisms 4 own plumbnesss of user, and keep this state by beading 1021 and depression 403a snap close, and keep this state by beading 1021 and depression 403a snap close, cut off and being connected in series of 5 of socket mechanisms, then, the user can rotate 90 degree with keeping covering 701, to expose socket 501, outside the grafting as a plug 9, make civil power flow to circuit board 2 via a lead 8 (as shown in Figure 2) again.
