Abstract
The utility model relates to an electric wiring board. A bidirectional controllable silicon is arranged on a power supply switch; a pin of the power supply switch is connected with a second anode of the bidirectional controllable silicon in parallel and is accessed to the power supply; the pin of the power supply switch is connected with a control electrode of the bidirectional controllable silicon; and a first anode of the bidirectional controllable silicon is connected with a load end. The electric wiring board is simple in structure, safe in use, convenient for repair and high in reliability.
Description
Technical field
The utility model relates to a kind of electric wiring board.
Background technology
The common electrical wiring board that uses in the market, because switch all is mechanical contact switch, the long-time use easily damaged.
Summary of the invention
The purpose of this utility model is to provide a kind of and can increases the service life, and simple in structure, the electric wiring board that reliability is high.
The technical solution of the utility model is achieved in that a kind of electric wiring board, be provided with a bidirectional triode thyristor at mains switch, the pin of mains switch with connect power supply after the second plate of bidirectional triode thyristor is in parallel, the pin of mains switch is connected with the bidirectional triode thyristor control utmost point, and the first anode of bidirectional triode thyristor connects load end.
The utility model has the advantages that: simple in structure, use safety, easy to maintenance, reliability is high.
Description of drawings
Fig. 1 is the circuit theory diagrams of electric wiring board of the present utility model.
Embodiment
As shown in Figure 1, a kind of electric wiring board is provided with a bidirectional triode thyristor at mains switch 2, connects power supply after the pin 1 of mains switch 2 and the second plate of bidirectional triode thyristor 5 are in parallel, the pin 3 of mains switch 2 is connected with the bidirectional triode thyristor control utmost point 4, and the first anode 6 of bidirectional triode thyristor connects load end.
During the utility model work, when pressing power supply mains switch 2, the bidirectional triode thyristor control utmost point 4 obtains starting resistor, and bidirectional triode thyristor conducting load end gets electric, again presses mains switch 2 when needing outage and disconnects the bidirectional triode thyristor control utmost point 4 voltages, and bidirectional triode thyristor disconnects.The utility model utilizes former mechanical switch to control the two-way controlled purpose that can break to reach Switching Power Supply.Because of minimum by the electric current of former mechanical switch control bidirectional triode thyristor, and the Switching Power Supply of bidirectional triode thyristor control electric socket board can be pacified from several peaces to tens, even larger, and is contactless control.Its silicon controlled price can be described as economy very below 1 yuan.
