Description

Safety socket

Technical field

The utility model relates to the jack technology field, refers in particular to a kind ofly when not using here, and socket is respectively organized the supply socket of the difficult electric shock that is off state of jack.

Background technology

At present general supply socket, normally one group of power line is directly connected on two conductive holders in the socket, to be communicated with the inserted sheet of the plug that is inserted accordingly, jack because of supply socket, be generally open state, the child easily holds conducting objects and inserts, and causes taking place the accident of getting an electric shock.For avoiding this accident, and safety socket is arranged.The safety return circuit device patent of China Patent No. 2005100223587 disclosed sockets for example, the disclosed safety return circuit device of this patent, he is provided with power supply slot on a jack body, this power supply slot has in order to connect two jack bases of group appliance plug, and be equipped with power line, and between this power supply slot and power line and be provided with the loop of conducting electric current, this loop comprises a cross-over connection loop and some touch-controls loop, wherein this cross-over connection loop is located between this two jack base, have two inputs and transfer end, make an input and transfer end and be located at respectively these jack base two sides relatively, and be positioned at the relative input of same jack base two sides and transfer not connect between end and establish as the loop, and this two jack base input that homonymy is not adjacent with transfer end intercropping loop conducting and connect and establish; And these touch-control loops are divided between this two jack base and the cross-over connection loop, and with this two input, transfer end and connect as touch-control and to establish, in order to control between this cross-over connection loop and power supply slot, the conversion of normal opened contact and normally closed contact state, the short circuit of jack base loop conducting, open circuit, by the adjacent input of this two jack base and transfer touch-control circuit controls between end, the fail safe of using with certain lifting socket power.

Though the touch-control loop of the safety return circuit device patent utility model patent case of the socket of this patent provides four movable guide cards, and must four movable guide card all must all present the state of closed circuit ON, whole socket could normal power supply.This design seems fail safe at first blush than higher.Yet it is true really not so, because misplug into the width of metal insert when being not enough to touch two movable guide cards of same jack simultaneously, the two ends of metal insert are not under supporting, the movable guide card of any one rubber-like wherein can't be strutted and touches at all, be unnecessary so the two ends of same jack all are provided with the way of movable guide card simultaneously.Only need an end setting promptly enough in fact, can reach equally and this patent utility model patent identical functions.Four the movable guide cards and first jumper, second jumper are set, cause whole group socket to become very complicated, except increasing in rain the manufacturing cost, the probability that also more forms fault increases.Because use with the passing of time,,, still can't make four movable guide cards all closed circuit simultaneously and power even if be to use correct plug and correctly insert as long as when having any one movable guide card to cause loose contact in four movable guide cards because of elastic fatigue.Overall structure is very complicated, and the required component number is also more in addition, and manufacturing cost increases, and the fault probability increases, and manifests its shortcoming.
