Abstract

The utility model relates to a protection against electric shock safety socket, this socket comprises casing (1), separation blade (2), spring (3), locking couple (4), back lid (5), the utility model discloses utilized the inclined plane principle, made the relative motion take place between the inclined plane of the insulating separation blade of plastics and the plug, crowded the separation blade open to when the state of not inserting the socket, the separation blade is hung by the locking couple, thereby has realized the effect of safe protection against electric shock, has simple structure reasonable, advantages such as convenient to use.

Description

Electric shock-prevention safety socket

The utility model relates to a kind of household electrical appliances electrical materials and appliances, specifically a kind of electric shock-prevention safety socket.

At present; the socket that uses in sale and the family on the China market does not all have anti-electric shock apparatus; it is the catch that two electrodes do not block internal electric source in the receptacle sockets when socket does not use; though have on the market to sell now and have the socket of protecting catch; but also be to fail to play a protective role; there is electric leakage hidden danger, serious prestige rib child, children's life security.

The purpose of this utility model is to provide a kind of receptacle sockets to have the insulation catch, simple and reasonable electric shock-prevention safety socket.

The purpose of this utility model is to realize like this, this socket is by housing, catch, spring, the locking hook, bonnet is formed, block two supply hubs at the enclosure interior plastic insulation catch that a side section is set is the inclined-plane, having chute and hook hole on the catch also can slide up and down, the catch upper end is provided with spring, can it be resetted by spring, and when catch does not insert at plug, under the effect of spring, will block jack, catch after resetting is linked up with two rotary lockings that are provided with on the rotating shaft holder and is tangled below housing, the locking hook is by hook front, coupler body, back-moving spring, fixed axis constitutes, and coupler body is arranged on one side of hook front, and back-moving spring is sleeved on the fixed axis, coupler body can rotate with the hook front, has slideway above the bonnet.Two locking hooks are pushed at plug the two poles of the earth simultaneously when plug insertion socket, and with inoperative, catch can upwards slide the locking hook to catch, when plug continues to insert inwards, had an effect in the inclined-plane of catch, catch is upwards sliped off by slideway, plug just inserts smoothly, energized; When socket is in unused state, if child inserts wherein any one jack with fine wire etc., though one of them locking hook is open, but the hook of the locking in another jack is not open, so the plastic insulation catch is tangled by another locking, can not upwards slide, thereby reach the purpose of protection against electric shock.

The utility model has utilized inclined plane principle, make between the inclined-plane of plastic insulation catch and the plug relative motion takes place, catch squeezed open, and when not inserting the state of socket, the locked hook of catch tangles, thereby realized the effect of safety electric shock-prevention, had advantages such as simple and reasonable, easy to use.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is an electric shock-prevention safety socket overall structure schematic diagram.

Fig. 2-1,2-2,2-3 are electric shock-prevention safety socket user mode principle schematic.

Fig. 3 is an electric shock-prevention safety socket rear cover structure schematic diagram.

Describe concrete structure of the present utility model and use in detail below in conjunction with accompanying drawing.

As shown in Figure 1, this socket is by housing 1, catch 2, spring 3, locking hook 4, bonnet 5 is formed, the plastic insulation catch 2 that in housing 1 inside a side section to be set be the inclined-plane blocks two supply hubs, have chute 6 and hook hole 7 on the catch 2, and can slide up and down by the slideway 14 above the bonnet 5, catch 2 is provided with spring 3, can it be resetted by spring 3, and catch 2 is not when plug inserts, under the effect of spring 3, will block jack, two rotary locking hooks 4 that are provided with on the hook rotating shaft holder 8 of catch 2 after resetting below housing 1 tangle, locking hook 4 is by hook front 9, coupler body 10, back-moving spring 11, fixed axis 12 constitutes, coupler body 10 is arranged on one side of hook front 9, and back-moving spring 11 is sleeved on the fixed axis 12, and coupler body 10 rotates with hook front 9, the back of bonnet 5 has electrode tip holder, and three electrodes contact with plug 13 by three holes on the bonnet 5.Schematic diagram when Fig. 2-1 does not insert jack for plug 13, this moment, catch 2 was in the lock state.By Fig. 2-2, coupler body 10 will break away from hook hole 7 when plug 13 inserts socket, and plastic insulation catch 2 is released, and two locking hooks 4 are pushed at plug 13 the two poles of the earth simultaneously, and 4 pairs of catch 2 of locking hook are with inoperative, and catch 2 can upwards slide.When plug 13 continues to insert inwards (shown in Fig. 2-3), had an effect in the inclined-plane of catch 2, catch 2 is upwards slided along the slideway on the bonnet 5 among Fig. 3 14, plug 13 just inserts smoothly, energized.When socket is in unused state, if child inserts wherein any one jack with fine wire etc., though one of them locking hook 4 is open, but the hook of the locking in another jack 4 is not open, so plastic insulation catch 2 is tangled by another locking hook 4, can not upwards slide, thus the function of realization protection against electric shock.
