Description
Technical field
The present invention relates to a kind of switching device, particularly a kind of explosion-proof rocker switch.Belong to the appliance switch field.
Background technology
Though the existing rocker switch that is used to cut-off circuit is simple in structure, easy to use, its contact does not have sealed, and the electric arc and the external world that produce during switching circuit communicate, and are not suitable for being used in inflammable and explosive workplace.
Summary of the invention
The invention reside in the deficiency that solves existing switch designs, a kind of explosion-proof rocker switch is provided, switch contact is placed in the enclosed switch core assembly, solve explosion-proof problem, also more simple and reliable on the structure.Be applicable to as indoor power switch and other purposes mains switch.
The present invention is achieved by the following technical solutions, the present invention includes: control seesaw, have the enclosed switch core assembly of controlled seesaw, three binding posts that are connected with external circuit.Its principal character is: the control seesaw is in enclosed switch core outside, and respectively there is a control permanent magnet at the seesaw two ends.Controlled-rocker is in enclosed switch core assembly the inside, and also respectively there is a controlled permanent magnet at the seesaw two ends.Two permanent magnet magnetic polarity of two seesaw the same sides are that opposite working attracts mutually.Also respectively there is a moving contact at the two ends of controlled-rocker, and two moving contacts connect with lead, and this lead is connected with switch terminal with flexible conductor.Press the control seesaw, corresponding lifting up just done at the controlled-rocker two ends, and at the end that the control seesaw is pressed, two seesaws attract, at two seesaws of an end of controlling the seesaw perk separately.Controlled seesaw is whenever lifted up once, wherein one group of contacting of switch, and another group contact disconnects.The part of three binding posts is in enclosed switch core assembly the inside, one of them two moving contact as common port and controlled-rocker is connected, each is connected two other binding post with corresponding fixed contact, and the position of fixed contact is corresponding with the moving contact of controlled-rocker.Another part of three binding posts is used for being connected with external circuit in enclosed switch core outer end.Controlled-rocker and binding post after this inner chamber is pumped into vacuum, inject protective gas or arc extinguishing gases behind the switch inner chamber of packing into, and strict sealing.
Wherein, the control seesaw amplitude of lifting up outside the enclosed switch core is greater than the controlled-rocker amplitude of lifting up.So that act on the attraction of corresponding controlled permanent magnet by the control permanent magnet of lower end, the control permanent magnet that is greater than the perk end acts on the attraction of corresponding controlled permanent magnet.Two permanent magnet opposite working of control seesaw and controlled-rocker the same side attract mutually, and these two seesaw states are always controlled that end that seesaw presses and attracted each other, and that end of control seesaw perk separately.
Wherein, permanent magnet can be made with strong magnetic such as rubidium iron boron.Contact described here refers to silver contact, or other has the synthetic contact of superior electrical conductivity energy.
The present invention is through above design; the power that is subjected to during two seesaw operations is just smaller and even, and the switch core assembly is injected protective gas or arc extinguishing gases and sealing after vacuumizing, and has protected the contact; improve the life-span and the reliability of rocker switch significantly, and solved explosion-proof problem.
