[embodiment]
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
Embodiment one
Please refer to shown in Figure 1, be these routine circuit theory diagrams, the firewire jack downside that the first K switch 1-1 of first switches set, second switch K1-2 are installed in socket, the 3rd K switch 2-1 of second switch group, the 4th K switch 2-2 are installed in the zero line jack downside of socket, and the first K switch 1-1 of first switches set and the 3rd K switch 2-1 of second switch group, the contact of firewire jack are in series, and the 4th K switch 2-2 of the second switch K1-2 of first switches set and second switch group, the contact of zero line jack are in series.
The supply socket that this is routine, mechanical structure comprise housing, are mounted on the power supply output plughole on the case panel more, and every group of power supply output plughole includes a firewire jack, a zero line jack; Be provided with the contact that is used to conduct electricity in each firewire jack, the zero line jack.
Mechanical structure that this is routine and operation principle are please in conjunction with Fig. 2, Fig. 3, shown in Figure 4, set up first slide block 10, second slide block 20 at housing, as each back-moving spring of return unit: first left back-moving spring 11, the first right back-moving spring 12 and the first intermediate reset spring, 13, the second left back-moving springs, the second right back-moving spring and the second intermediate reset spring.
When the inserted sheet of plug inserts firewire jack, first slide block 10 promotes the first K switch 1-1 of first switches set, the contact of second switch K1-2, make it closed simultaneously, because the 3rd K switch 2-1, the 4th K switch 2-2 of second switch group are not closed, zero line jack, firewire jack no power; In like manner, when the inserted sheet of plug inserts zero line jack, the 3rd K switch 2-1, the 4th K switch 2-2 that second slide block 20 promotes the second switch group makes its switch contact closed simultaneously, because the first K switch 1-1, the second switch K1-2 of first switches set are not closed, the zero line jack of socket, firewire jack be no power also.When having only two inserted sheets of plug to insert zero line jack, the firewire jack of socket simultaneously, four switches of the first K switch 1-1, the second switch K1-2 of first switches set and the 3rd K switch 2-1 of second switch group, the 4th K switch 2-2 are closed simultaneously, and supply socket could be switched on.Corresponding first left back-moving spring 11, the first right back-moving spring 12 that is provided with between the right and left shoulders of first slide block switch contact corresponding with it; The corresponding second left back-moving spring, the second right back-moving spring of being provided with between the right and left shoulders of second slide block switch contact corresponding with it; When the plug in the supply socket was transferred to, under the effect of aforementioned each back-moving spring, first slide block 10, second slip, 20 disengagings were pushed each switch contact, are reset to the home position, and above-mentioned four switches are all disconnected.As shown in Figure 4, first or second slide block adopts the ramp structure design, and can the size of the length decision inserted sheet on inclined-plane lead in the pull switch winding; Each slide block all adopts left and right sides back-moving spring, can prevent the plug individual difference may cause switch can not closure or slide block by dieback, can avoid the less metal object diplopore of size to insert socket or thicker metal object single hole inserts the electric shock accidents that socket causes, guarantee to insert socket plug must with the standard plug size near the time socket just can switch on; Thereby fail safe of the present utility model is further improved.In addition, for the reliability that guarantees to reset, the first intermediate reset spring, 13, the first intermediate reset springs 13 have been set up between first slide block 10 and first switches set between first left back-moving spring 11, the first right back-moving spring 12; In like manner, set up the second intermediate reset spring between second slide block 20 and the second switch group.
So socket of the utility model embodiment, when having only the single plug slice of zero line jack or firewire jack to insert, the equal no power of socket, must have plug to insert at zero line jack, the firewire jack of socket simultaneously and insert the plug of socket must be with the standard plug consistent size time socket just switch on, so the utility model embodiment socket can avoid metal object to insert the electric shock accidents that the socket single hole causes.
Embodiment two
According to circuit theory shown in Figure 1, the supply socket that this is routine, in zero line jack or firewire jack, what be separately installed with one group of double-throw often opens key switch, and its contact lays respectively at zero line jack or firewire jack bottom.In like manner, connect according to circuit theory shown in Figure 1, when having only zero line jack or firewire jack to be inserted simultaneously by plug slice, when pushing two groups of double-throws and often opening the key switch contact, supply socket could be switched on.
Embodiment three
Please refer to shown in Figure 5ly, the difference of this example and embodiment one is, omitted the intermediate reset spring of first switches set, second switch group in this example; Reset with the first left back-moving spring, the first right back-moving spring in first switches set, reset with the second left back-moving spring, the second right back-moving spring in the second switch group.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.For example the installation site of each back-moving spring can be different from the foregoing description; Each switches set can also only use a back-moving spring to be used to reset.
