Description

A kind of safety power source plug socket

The utility model relates to a kind of consuming device that is used for every field such as industrial and agricultural production and life, work, place.

Supply socket is the consuming device of every field such as industrial and agricultural production and work, life, place extensive use.At present, normally used supply socket is divided into fixed and movable two kinds generally, and its jack can be divided into common open type again and band is protected two kinds of gate-types.These electric outlet structures are fairly simple, and live wire and zero line are all directly received on the binding post, use for external power consumption equipment.But; this kind supply socket exists very important shortcoming and unsafe factor; be that it can only lean on simple basic insulation to protect for live wire and element; lack the necessary security defencive function; thereby can not prevent effectively transgression for using electricity and people be misplug into etc. behavior cause use electrification, have the hidden danger that threatens Electrical Safety.

The purpose of this utility model be to provide a kind of prevent because of misplug into etc. the electric shock accidents that causes of reason, the safety power source plug socket of guaranteeing safety utilization of electric power.

The utility model is to realize like this.This kind safety power source plug socket adopts by link gear indirectly to the mode of socket inner spring sheet power supply, the mode that socket inner spring sheet is directly powered that substitutes that existing socket adopts usually.That is, a link gear that is made of gangbar, spring, sliding contact is set in the jack of this kind socket, when inserting jobbie in usual state and single jack, the supply line in the socket can not connect, and the spring leaf in the jack is all not charged.Have only when attaching plug evenly inserts each jack, the latch of attaching plug acts on link gear, sliding contact on the link gear is connected two place's breakpoints in the supply line in the supply socket respectively, spring leaf in the socket is just charged at this moment, possesses the condition to attaching plug and power consumption equipment normal power supply.Like this, just, can reach the purpose of guaranteeing safety utilization of electric power.In addition, fuse is housed also in this kind safety power source plug socket, thereby can limits its power consumption flexibly, power consumption equipment is carried out necessary protection by changing tubular type fuse-link specifications and models.The circuit-closed tell-tale that installs in this socket then can make it use and detect more convenient.

The utility model modern design; rational in infrastructure; utilize it can prevent effectively because of the people be misplug into or the personal injury that causes of transgression for using electricity; guarantee Electrical Safety; wherein the fuse of equipment and circuit-closed tell-tale can play protection power consumption equipment and the convenient effect of using, detecting respectively, are suitable for extensive popularization to be adopted.

Fig. 1, Fig. 2 are respectively general structure front and back schematic diagram of the present utility model.

Fig. 3, Fig. 4 are respectively A-A, the B-B cutaway view of jack.

Fig. 5 is the C-C cutaway view of fuse.

Below in conjunction with accompanying drawing enforcement of the present utility model is described further.

As shown in the figure, the utility model is by shell 1, single-phase three utmost point jacks 2, single-phase two utmost point jacks 3, power supply indicator 4, fuse 5, three utmost point jack binding post groups 6, two utmost point jack binding post groups 7, indicator lamp terminal 8, fuse binding post 9, spring leaf 10, plastic insulator 11, screw 12,18,21, gangbar 13, baffle plate 14, spring 15,19, fixed contact 16, sliding contact 17, pole plate 20 and tubular type fuse-link 22 are formed, its structure, the assembling feature is as follows: shell 1 front is provided with single-phase three utmost point jacks 2, single-phase two utmost point jacks 3, power supply indicator 4 and fuse 5, the back side are provided with three utmost point jack binding post groups 6, two utmost point jack binding post groups 7, indicator lamp terminal 8 and fuse binding post 9; Spring 15 and baffle plate 14 are equipped with in gangbar 13 its inboards that the pointed inclined-plane of front end band is housed in plastic insulator 11 chambeies that are provided with in the jack 2,3, the below is provided with sliding contact 17, insert screw 12 respectively in 3 screws of the plastic insulator of each jack 11 bottom surfaces, screw-driving " recessed " font spring leaf 10 wherein, two screw tops are provided with fixed contact 16 in addition, and each screw lower end links to each other with binding post group 6,7 with screw thread respectively; Tighten with screw 18 and shell 1 on plastic insulator 11 tops of fuse 5, both sides are respectively equipped with " L " shape pole plate 20 in the chamber, 20 of two-plates are provided with tubular type fuse-link 22 and spring 19, the circular hole of two-plate 20 lower, transverse sections penetrates screw 21 respectively, penetrate insulator 11 bottom surface screws again, and be connected and fixed with binding post 9.The order of connection (see figure 2) of this safety power source plug socket inside is as follows: power firestreak is received on the binding post A, and post D is connected with binding post E, is breakpoint between binding post A and B, C and the D, needs to connect with the sliding contact of link gear; Zero-power line is connected with binding post F, and earth connection is connected with binding post G; Receive respectively on binding post B and the binding post C at the two ends of fuse, and receive respectively on binding post E and the binding post F at the two ends of power connection indicator light.When attaching plug inserts socket, the thrust of attaching plug latch moves gangbar on gangbar front end inclined-plane inwards, this moment the gangbar below sliding contact with within move, binding post A and B, binding post C and D are connected respectively, can form the work loop of a closure.When attaching plug was extracted, the gangbar spring-loaded was outwards moved, and drives sliding contact simultaneously and moves outward, made binding post A and B, binding post C and D disconnect, and can cut off the electricity supply.
