Abstract
The utility model relates to a permanent magnetic seesaw switch which is a switch for a common electric appliance. The permanent magnetic seesaw switch comprises an insulating casing, a seesaw, a yoke, a contact, conducting wires, etc. Through the way that the two poles of a permanent magnet move in a groove, the yoke and a seesaw armature form a magnetic loop to absorb the armature left and right so as to turn on and turn off the circuit. Completely sealed, the utility model has the advantages of explosion prevention and friction prevention.
Description
The utility model relates to a kind of no spring, sealing, permanent magnetism power, manually appliance switch.
The general at present switch that uses all is to switch detent force with the spring, and as flat switch, air switch, this switch access times are many will to be caused, relaxing of spring, and detent force is not enough, switches damping.Because spring is as switching power, structure is tightly played inadequately, mechanical friction and wearing and tearing are big, cracky, contact not steady, contact easy burn-out etc.And the permanent-magnetic switching of present patent applied for, its structure is compact inadequately, and poor practicability is similar to according to the retrieval the patent No.: ［ 1 ］ CN2086936U, ［ 2 ］ CN88212726U.
The utility model switch is the magnetic force diverter switch, and no spring does not have mechanical switching device shifter, and compact conformation is to prolong working life.The design of handle slide block structure is changeable to be purpose.
The utility model design is a kind of permanent magnetism rocker switch.The contact of this switch is sealed in the insulation shell, is isolated from the outside.Form magnetic loop by the seesaw armature of magnetic field of permanent magnet in yoke and housing, inhale moving seesaw, make the moving contact motion.Moving contact connects with the place of connecing in the fixed contact wherein, and two external places of fixed contact connect external circuit.Permanent magnet moves switching field and drives moving contact motion simultaneously and make the circuit Push And Release.
This on-off ratio switch of the same type in the past has following advantage:
［ 1 ］ by magnetic force as switching power, saved spring and mechanical device.Switch is durable in use, uses steadily reliable.
［ 2 ］ by yoke transmission magnetic field, the housing thickness does not influence switching power.
［ 3 ］ moving contact is the seesaw type motion, and the contact of switch is strong with the disconnection performance.
［ 4 ］ profile of handle slide block can arbitrarily design.
［ 5 ］ because contact is sealed in the housing, be isolated from the outside, but life-saving, and anti-riot, anti-puckery.
This switch concrete structure is by description of drawings.Accompanying drawing ［ 1 ］ cuts open figure for the front of switch, and figure ［ 2 ］ cuts open figure for face then.
This switch case ［ 1 ］ is insulation, seal, and two fixed contacts ［ 2 ］ and ［ 3 ］ are equipped with in the bottom, and external place and circuit join.Wherein a fixed contact ［ 3 ］ in meet the place and connect with moving contact by lead ［ 4 ］.Moving contact and armature are one, i.e. seesaw ［ 5 ］.Moving contact is an electric conductor, and armature is magnetic conductor.Permanent magnet ［ 6 ］ magnetic field forms the loop through yoke ［ 7 ］ and armature ［ 5 ］, inhales moving seesaw.Yoke is two pairs of magnetic conductors, is separated by insulating material, forms a groove.When hand propelled slide block ［ 8 ］, permanent magnet is moved in the yoke groove, magnetic field is conversion in groove, makes the magnetic loop conversion, drives seesaw and moves up and down, and moving contact and fixed contact ［ 2 ］ form connection and disconnect the circuit Push And Release simultaneously.
Claims (3)
1, permanent magnetism rocker switch insulation shell (1) is seesaw (5), yoke (7) and fixed contact (2) (3) are encapsulated in the housing (1), the chute that yoke (7) is formed is installed in the top of housing (1), seesaw (5) is installed in housing (1) cavity and yoke (7) triangle bottom, and hold by permanent magnetic field, fixed contact (2) and (3) are installed in the bottom of housing, wherein the contact is connected by lead (4) with seesaw (5) one ends in the shell of a contact (2) or (3), the outer contact of the shell of contact (2) and (3) connects external circuit, it is characterized in that permanent magnet (6) is by the moving seesaw (5) of yoke (7) suction, when permanent magnet (6) slides in yoke (7) groove, inhale moving seesaw (5) motion simultaneously circuit is opened or closed.
2, permanent magnetism rocker switch according to claim 1 is characterized in that seesaw (5) is to be made by one deck magnetic conductor and the combination of another layer electric conductor.
3, permanent magnetism rocker switch according to claim 1; it is characterized by the yoke groove (7) that the chute of permanent magnet (6) motion is made up of four magnetic conductors; and the moving contact on the seesaw (5) shielding is isolated from the outside protection contact life-saving in the housing chamber with housing (1).
