Fig. 2 is the external structure schematic diagram of the utility model embodiment
Fig. 3 is the syndeton schematic diagram of each terminals among the utility model embodiment.
Embodiment
As shown in Figure 1, the timing rotating shaft 4 that is driven by electrical micro-machine 2 and reducing gear 3 is installed in the housing 1 of the utility model timing power supply device and is installed in cam 5 in the regularly rotating shaft, reducing gear is made of a pair of reduction gearing.Cam 5 can push elasticity movable contact spring 6, makes its swing, static contact 7 and back static contact 8 before forward and backward being respectively arranged with of movable contact spring.Between preceding static contact and the elasticity movable contact spring is normally opened contact 9, is normally-closed contact 10 between back static contact and the elasticity movable contact spring.
In hull outside a power input plug 11 and timing knob 12 (as Fig. 2) are installed.Terminals A in power input plug and the housing is connected with terminals B; Two binding posts of electrical micro-machine are respectively terminals E and terminals F; Elasticity movable contact spring 6, preceding static contact 7 and back static contact 8 are connected terminals C, D and G respectively.
As shown in Figure 3, line end A be connected on the power output end X after terminals E is connected, terminals B is connected with terminals C, terminals F be connected on another power output end Y1 after terminals D is connected, X and Y1 constitute the output that regularly cuts off the power supply; Terminals G is connected with the 3rd power output end Y2, and X and Y2 constitute the output of regularly switching on.
In actual use, if the utility model device and electrical appliance (as charger etc.) are made when as a whole, power output end X, Y1, Y2 directly insert in the operating circuit of electrical appliance; If device of the present utility model is as one independently during product, then can be on housing 1 fixedly connected power output socket 13 (as Fig. 1), power output end X, Y1, Y2 promptly are linked in the power output socket.
The course of work of the utility model embodiment is as follows:
When rotary knob 12 made cam go to the special angle scope, elasticity movable contact spring 6 was made normally opened contact 9 conductings by cam jack-up forward, and electrical micro-machine 2 obtains power supply and starts working, and voltage output is arranged on power output end X and Y1 simultaneously; When the certain timing of process (by the initial angle position decision of cam), cam is jack-up elasticity movable contact spring 6 no longer, elasticity movable contact spring 6 relies on self elastic reset, normally opened contact 9 disconnects, promptly on power output end X and Y1, realize regularly outage, normally-closed contact 10 recovers conducting simultaneously, promptly realizes regularly energising on source output terminal X and Y2.
