The utility model has the advantages of simple and reasonable structure, convenient repair and use, low cost, easy fabrication, no direct electrification of the socket, no damage when contacting, high safety, and long service life.

Description

The electronic security(ELSEC) socket

The utility model relates to a kind of socket, particularly a kind of electronic security(ELSEC) socket.

Existing all kinds of electronic receptacles, its socket is all directly charged, so that child's touch causes the electric shock injures and deaths.

The electronic security(ELSEC) socket that provides a kind of socket directly charged, safe and reliable, not simple and reasonable is provided the purpose of this utility model.

The purpose of this utility model can reach by following measure: the utility model comprises insulation shell, trip bolt, binding post, socket, insulating pad, it is characterized in that: also have functional block, micro-contact switch, micro-contact switch is arranged on below the zero line socket, the a end of functional block connects the phase line binding post, the b end connects the phase line socket, and the zero line binding post is connected with the zero line socket.

The purpose of this utility model can also reach by following measure: functional block is that single-phase bridge rectification connects by rectifier diode Z1～Z4, its output a, b are connected with collector electrode and the emitter-base bandgap grading of triode BG respectively, and base stage and the micro-contact switch of triode BG join.

Fig. 1 is a structure front view of the present utility model;

Fig. 2 is a structure chart of the present utility model;

Fig. 3 is the line map of the utility model functional block.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

Among Fig. 1-Fig. 2,1 is that insulation shell, 2 is that trip bolt, 3 is that jack, 4 is that phase line binding post, 5 is that earth terminal, 6 is that zero line binding post, 7 is that functional block, 8 is that socket, 8-1 are that zero line socket, 8-2 are that phase line socket, 9 is that micro-contact switch, 10 is an insulating pad.Micro-contact switch 9 is arranged on below the zero line socket 8-1, directly controls break-make by plug.The a end of functional block 7 connects phase line binding post 4, and the b end connects phase line socket 8-2; Zero line binding post 6 is connected with zero line socket 8-1.Trip bolt 2 is arranged on housing central authorities; Insulating pad 10 is assembling and fixed socket position.

Among Fig. 3, functional block 7 is made of rectifier diode Z1-Z4, switch triode BG; Diode Z1-Z4 is that single-phase bridge rectification connects, and its output a, b are connected with collector electrode and the emitter-base bandgap grading of triode BG respectively, and the base stage of triode BG and micro-contact switch 9 join.

During work, plug insertion socket 8, shake-up is loaded on the micro-contact switch 9 below the zero line socket 8-1, and it is connected, and this moment, the base stage of triode BG had triggering level, made its conducting, i.e. phase line binding post 4 and line socket 8-2 connection mutually, whole socket 8 is charged work.

The utility model has following advantage compared to existing technology:

1, simple and reasonable, keep in repair easy to use, easy manufacturing, cost is lower.

2, socket is directly not charged, and touching does not have injury, and is safe and reliable, long service life.
