Abstract
The utility model belongs to a household electric appliance safety connecting device, comprising a bidirectional thyristor used as an electronic switching element, a bidirectional thyristor protection circuit, a bidirectional thyristor trigger circuit, and a socket; particularly a limit switch is arranged in the socket; the limit switch is connected with the trigger circuit. The utility model has the advantages of simple structure, safety, low cost, and convenient operation, particularly applied to household appliances.
Description
The utility model belongs to electric coupler spare, particularly relates to a kind of household electrical appliance interface unit.
Present widely used alternating-current switch and socket are to be switched on or switched off the control load electricity consumption by the spring leaf contact mostly.This switch and plug easily produce spark, and useful life is short, unreliable.Recent contactless socket or the switch that occurs; s' 92220721.6 patent " multi-functional adjustable electronic receptacle " as Liu Binshu in the application number of on September 25th, 1992 application; its circuit part comprises bidirectional triode thyristor, control circuit of bidirectional thyristor, power circuit, time control circuit and the silicon controlled rectifier protecting circuit as electronic switching element; its complex structure; safety in utilization is poor, and the cost height, uses operation inconvenience.
The purpose of this utility model is to provide a kind of household electrical appliance safety power distribution equipment simple in structure, safe and reliable, with low cost.
The utility model comprises band limit switch K
1Socket CZ, as the bidirectional triode thyristor SCR of electronic switching element
1, by capacitor C
1And resistance R
1The protective circuit (1) that series connection constitutes, protective circuit (1) is connected in parallel on bidirectional triode thyristor SCR

2Circuits for triggering (4), the one end is connected with power supply, and the other end and bidirectional triode thyristor SCR
2The control utmost point be connected.
Limit switch K
1Being the inching button switch, also can be snap switch.Hand switch K
2, K
3Be the locking push-button switch.
The utility model includes only bidirectional triode thyristor, socket and bidirectional triode thyristor circuits for triggering, and its structure is very simple.Owing to limit switch is housed on the socket, load circuit did not have electricity when load plug began the reed of contact base, had only when load plug to be inserted into the end soon and to stir limit switch K
1The time, load just has electricity (bidirectional triode thyristor SCR
1Just conducting), so when load powered up, socket can not produce sparking; When load plug is extracted, because limit switch K
1Disconnect bidirectional triode thyristor SCR in advance
1End, plug and Die for Reeds of Connector Jack disconnect again then, so plug also can not strike sparks when extracting, and be safe and reliable.After this circuit increased an electronic switch, function was more complete and have light-emitting diode to make index signal, uses easy to operate, the cost reduction.
Fig. 1 is a household electrical appliance safety power distribution equipment circuit diagram.
