Description

New-type circuit gauge tap
Technical field
The utility model relates to a kind of electronic devices and components, particularly belongs to a kind of switch that is applied to the smart machine in domestic circuit and Industry Control.
Background technology
Aspect circuit controling switch, most popular device mainly contains two kinds at present: one is controllable silicon, and another kind is relay.Controllable silicon is a kind of very important power device, can be used to do the control of high voltage and high electric current, although the shock-resistant ability of thyrister form switch is good and noncontacting switch electric arc, when its work, heating is large, thermal losses is higher; Relay is a kind of control element for gone to control large electric current running by little electric current equally, after relay-type switch conduction, internal resistance is less, electric energy loss is little, but when meanwhile its major defect is band inductive load, switching arc is larger, easily cause pitting of contact, adhesion, thereby cause relay to be scrapped.
Summary of the invention
The purpose of this utility model is to provide a kind of new-type circuit gauge tap, reduces thermal losses, increases the service life, safe and reliable object to reach.
New-type circuit gauge tap provided by the utility model, comprise base, shell and connection terminal, on base, be fixed with circuit board, on circuit board, draw terminals, it is characterized in that, described circuit board comprises silicon controlled module and relay module, and described silicon controlled module has controllable silicon and controllable silicon drive circuit, and relay module comprises relay and relay drive circuit; Described terminals comprise control output end, control electric signal input end and earth terminal; Controllable silicon is in parallel with relay normally open contact, and is connected to control output end; Above-mentioned controllable silicon drive circuit is connected power supply and controls electric signal input end with relay drive circuit.
In above-mentioned controllable silicon drive circuit, have photoelectrical coupler and transistor circuit, photoelectrical coupler connects respectively controllable silicon, power supply and transistor circuit, and transistor circuit connects controls electric signal input end;
In the driving circuit of relay, comprise that relay coil connects the second transistor circuit, power supply, the second transistor circuit connects control electric signal input end equally; And the transistor emitter in above-mentioned transistor circuit all connects earth terminal.
New-type circuit gauge tap provided by the utility model, in the time of conducting, controllable silicon conducts on first, secondly relay action that powers on, after controlled silicon conducting, its two ends pressure reduction is lower, therefore in the time of relay closes, relay two ends are almost without pressure reduction, so avoided the generation of electric arc and electric network pollution; Continue in turn on process, because relay contact contact resistance is minimum, therefore controllable silicon two ends, without pressure reduction, make switch without thermal losses at switch.In the time that switch disconnects, relay is power-off in advance, and in the time of contact separation, controllable silicon recovers conducting, thereby suppresses the generation of contact electric arc, has protected relay contact, and last controllable silicon disconnects, and completes the cut-out of switch.The utlity model has without electric arc and circuit pollution, the good effect that safe and reliable, grow serviceable life.
