Description
Technical field
The present invention relates to a kind of contactor.
Background technology
Existing contactor comprises base and pedestal, is provided with supporter, back-moving spring and fixed contact in the described pedestal; Be provided with coil, fixed armature and instruction terminal in the described base; Described supporter is provided with moving contact, is provided with movable core in the described coil, and described movable core is fixedlyed connected with supporter; Described instruction terminal two ends are connected respectively to coil and outside control circuit.When the instruction terminal is accepted the power on signal of external control circuit, this voltage signal is added on the coil, behind the coil electricity, produce suction between fixed armature and the movable core supporter is moved downward, make moving contact with fixed contact closure (for normally opened contact) or separate (for normally-closed contact).Otherwise, when the instruction terminal is accepted the power-off signal of external control circuit, coil blackout, producing suction between fixed armature and the movable core eliminates, supporter moves upward under the effect of back-moving spring, drives moving contact and separates (for normally opened contact) or closed (for normally-closed contact) with fixed contact.Because the control circuit of existing contactor is external, need additionally take up room, and wiring is unreliable.
Summary of the invention
What the present invention will solve is the bigger problem of small product size that prior art exists, and aims to provide a kind of contactor of compact conformation.
The present invention also will solve the insecure problem of wiring that prior art exists, and aims to provide the reliable follow-on contactor of a kind of easy-to-connect.
The technical scheme that addresses the above problem employing is: contactor, comprise base and pedestal, and be provided with supporter, back-moving spring and fixed contact in the described pedestal; Be provided with coil, fixed armature and instruction terminal in the described base; Described supporter is provided with moving contact; Be provided with movable core in the described coil, described movable core is connected with described supporter; It is characterized in that also being provided with in described base control circuit board, the input of described control circuit board and output are connected respectively to instruction terminal and coil; Described base side wall is provided with location notch longitudinally, and described control circuit board inlay card is in described location notch.
During the energising of instruction terminal, through the control circuit board calculation process, be added to again on the coil, when voltage reaches certain value, produce suction between fixed armature and the movable core supporter is moved downward, moving contact and fixed contact are connected (for normally opened contact) or are disconnected (for normally-closed contact).When outage of instruction terminal or voltage drop to certain value, through the control circuit board calculation process, be added to again on the coil, fixed armature and movable core are under the effect of spring reset power, supporter resets, and moving contact and fixed contact disconnect (for normally opened contact) or connect (for normally-closed contact).
As a further improvement on the present invention, described instruction terminal comprises a terminal screw, a lug plate and a compressing tablet that is sleeved on the described terminal screw, and described terminal screw art end screws in the screw of offering on the described lug plate; Also be provided with a cover on the described base, in the draw-in groove that described terminal screw inlay card is offered on described cover.During wiring, lead is inserted between lug plate and the compressing tablet, screw terminal screw and make the lead secure fixation.
Improve as a step more of the present invention, described location notch is to be made of projection and end face and/or adjacent projection and projection.
According to the present invention, described control circuit board can be single circuit board, also can be the assembly that is made of a plurality of circuit boards.
