Abstract

The utility model relates to electrical equipment, in particular to an explosion proof and water proof magnetic electric appliance switch. The electric appliance switch consists of a bottom seat (9),an upper cover (3), a gland (2) and a knob (1), wherein, six plane contacts (10) and a guide column (6) are evenly distributed and fixed on the bottom seat (9); an insulated air chamber (14) is arranged under the upper cover (3), and the insulated air chamber (14) is filled with sulfur hexafluoride and provided with a movable contact sliding block (5); two permanent magnets (12) are symmetrically fixed in the center of the movable contact sliding block (5), the magnetic poles at the both ends are the same, three planar movable contacts (11) are evenly distributed under the movable contact sliding block (5), and a guide hole is arranged under the movable contact sliding block (5); the electric appliance switch has the advantages that the explosion proof performance and the water proof performance are good, and the electric appliance switch is suitable for being used for various explosion proof water proof places; the contacts adopt surface contact, pressure generated by magnetic force all the time is acted on the contacts, and the contact is good; when the electric appliance switch is turned on or off, the electric appliance switch dose not scatter arc light nor strike fire, the service life is long, the structure is simple, and the cost is low.

Description

Anti-riot waterproof magnetic force appliance switch

Technical field

The utility model belongs to electric equipment, particularly a kind of anti-riot waterproof magnetic force appliance switch.

Background technology

At present, appliance switch is of a great variety, no matter be anti-riot and non-anti-riot switch, its control all is to take machinery or electrical control, and connected mode is a disconnecting link, or jack type; Their weak point is: for anti-riot construction of switch complexity, anti-riot waterproof effect is undesirable; For the connected mode of disconnecting link or jack, contact badly, often burn out plug, useful life is short, often occurs sparking, arcing light during switch.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of anti-riot, waterproof is provided, and contact is the face contact and applies a pressure all the time, not arcing light, and not sparking, simple in structure, the anti-riot waterproof magnetic force appliance switch of long service life.

The technical scheme that the utility model technical solution problem adopts is: a kind of anti-riot waterproof magnetic force appliance switch of being made up of base, loam cake, gland and knob is characterized in evenly distributing on base and fixes six planar contact and lead; Be provided with the insulation air chamber below the loam cake, adorn a moving contact slide block versatilely in the insulation air chamber; The center is fixed two movable permanent magnets symmetrically above the moving contact slide block, and the two ends magnetic pole is identical, below evenly distribute and fix three plane moving contacts, and be provided with pilot hole; Movable permanent magnet below the knob on center and the moving contact slide block is corresponding fixes four fixing permanent magnets, and two fixing permanent magnet magnetic poles of relative angle are identical, and the S utmost point or the N utmost point be in the upper end, and another is on the contrary, and the N utmost point or the S utmost point are in the upper end; The insulation air chamber is a vacuum or insulation gas filled.

The beneficial effects of the utility model are: the anti-riot water resistance of this electric switch is good, is applicable to various anti-riot waterproof place; Contact is face contact, and a pressure that all the time magnetic force is arranged and produced does thereon, contacts; Not arcing light is not struck sparks during switch, and long service life is simple in structure, and cost is low.

Embodiment

With reference to accompanying drawing, a kind of anti-riot waterproof magnetic force appliance switch is made up of base 9, loam cake 3, gland 2 and knob 1, is characterized in evenly distributing on base 9 fixing six planar contact 10 and lead 6; Be provided with insulation air chamber 14 below the loam cake 3, be filled with sulphur hexafluoride and a moving contact slide block 5 is housed versatilely in the insulation air chamber 14; Centers are fixed two permanent magnets 12 symmetrically above the moving contact slide block 5, and the two ends magnetic pole is identical, below three the plane moving contacts 11 that evenly distribute, and be provided with pilot hole 4; Moving permanent magnet 12 below the knob 1 on center and the moving contact slide block 5 is corresponding fixes four fixing permanent magnets 13, and two fixing permanent magnet 13 magnetic poles of relative angle are identical, and the S utmost point or the N utmost point be in the upper end, and another is on the contrary, and the N utmost point or the S utmost point are in the upper end; Insulation air chamber 14 is for vacuum or be filled with the sulphur hexafluoride insulating gas.Fixedly connected between gland 2 and the loam cake 3, knob 1 is housed in the gland 2 versatilely, be carved with the mark 15 of four switches above the gland 2; Contact 10 fixedly connected binding posts 8 are connected with power supply with electric equipment respectively; Moving contact slide block 5 is provided with six pilot holes 4, is set with versatilely on six leads 6 that are fixed on the base 9, guarantees that moving contact 11 accurately contacts with contact 10.

The operation principle of this switch, exactly by moving the principle that permanent magnet 12 and fixing permanent magnet 13 the two poles of the earth are inhaled mutually and repelled each other, when knob 1 rotation 90 is spent, wherein a pair of fixing permanent magnet 13 on the knob 1 then repels each other when identical with moving permanent magnet 12 magnetic poles, and switch disconnects, when turning 90 degrees again, another is then inhaled when opposite with moving permanent magnet 12 magnetic poles mutually to fixing permanent magnet 13, switch connection, moving contact 11 has magneticaction all the time last during connection, has guaranteed that the contact of two contacts is good all the time.
