Abstract
The utility model discloses a permanent magnet type explosion proof and waterproof switch, which belongs to a connecting piece of an electrical apparatus element. The utility model mainly adopts the magnetic force of a permanent magnet to drive the power supply to be turned on or turned off, changing the mode of the present general switch sealed by a direct sealing surface. The entire switch without a contact surface has high explosion-proof and waterproof functions, meeting the requirements of chemical industries, coal mines, underwater, and milling working. The utility model which is simple has the advantages of easy manufacture, and low cost.
Description
The explosion-proof water proof switch of permanent magnet formula is the connector that belongs to electric elements.
Be used for reaching under chemical industry, weaving, the coal mine performance requirement that the required appliance switch of underwater work will possess explosion-proof waterproof.Present most of switch mostly is to carry out explosion-proof waterproof with the form of sealing surface except that straight blank pipe in order to satisfy above-mentioned requirements.Because the switch working face is contact-making surface, long-term work, the sealing surface abrasion, the generation of rubber is worn out, and as can not running check, will have an accident, and brings serious loss to the country and people.
The mode that the utility model utilizes the magnetic force of magnet to come indirect starting switch changes the form that switch at present commonly used directly seals by sealing surface, realizes the purpose of explosion-proof waterproof, prevents owing to the blast danger of accident of the problem of sealing surface.
The explosion-proof water proof switch of permanent magnet formula is to utilize between the permanent magnet to interact, and opens or closes circuit indirectly across sealing surface.It is made of housing, jump ring, main knob, slave knob, magnet, graphite electrode, electroconductive elastic sheet, main shaft and bonnet.Adorn severally to permanent magnet on the main knob, and that slave knob also is equipped with is several to permanent magnet.Slave knob and graphite electrode are fixed together with main shaft.Main knob is fixed on the housing with jump ring.When main knob rotates, because the interaction of permanent magnet on the driving and driven knob and rotating together, thereby driving graphite electrode rotates together, when graphite electrode contacts with electroconductive elastic sheet with regard to energized, when leaving, realize opening or closing the purpose of circuit with regard to powered-down.Main shaft is installed in the recess of housing and bonnet.Between housing and the bonnet,, also add rubber cushion and seal except with the contact-making surface.
The explosion-proof water proof switch of permanent magnet formula is compared with existing switch, and it utilizes indirect the opening or closing of circuit of carrying out of magnetic force of magnet to close, and whole switch all is quiet contact-making surface sealing, prevents when present switch from working because the form of moving contact-making surface sealing.Adopt graphite electrode to contact with metal clips, frictional force is few, and work is flexible, and prevents sintering phenomenon between the metal.

Embodiment of the present utility model: the explosion-proof water proof switch of permanent magnet formula mainly contains: housing, driving and driven knob, magnet, graphite electrode, electroconductive elastic sheet, main shaft and bonnet are formed.Housing and bonnet all can adopt hard mold molded.2 pairs of permanent magnets are housed on the main knob, and the logarithm of magnet can be according to the thickness of contact-making surface between housing and the main knob, guarantees the convenience that opens or closes of switch and decide.Main knob is fixed on the housing with jump ring.The logarithm of magnet and the magnet on the main knob are same on the slave knob, and magnet is fixed on the driving and driven knob.Graphite electrode can be a cuboid, also can divide two, but all will be fixed up with connecting plate.Main shaft can be with moulding manufacturing firmly, and it is fixed together slave knob, graphite electrode, can rotate with main knob.Main shaft is mounted on the concave station of housing and bonnet.Electroconductive elastic sheet can be used the scale copper manufacturing, is screwed on bonnet, and is communicated with binding post, after binding post connects lead, once seals with pitch.Except sealing surface is arranged, add rubber blanket during combination between bonnet and the housing, be screwed at last, add sealant tape on the screw and seal.
The utility model, simple in structure, easy to process, cost is low, the performance height of explosion-proof waterproof.
Claims (1)
1, the explosion-proof water proof switch of a kind of permanent magnet formula, form by housing, bonnet and binding post, it is characterized in that on main knob and the slave knob permanent magnet being housed, main knob is fixed on the housing with jump ring, slave knob and graphite electrode are fixed together with main shaft, main shaft is placed on the concave station of housing and bonnet, and electroconductive elastic sheet is screwed on bonnet, adds seal gasket on housing and the bonnet contact-making surface and forms the explosion-proof water proof switch of permanent magnet formula.
