Abstract
The utility model discloses a sealed and magnetic explosion and water preventing seesaw type power supply switch and comprises a seesaw type button, a main body component and a line connecting component, wherein the seesaw type button is provided with an upper magnetic body which is connected with two magnets by a magnetic clutch and a trapezoidal magnetic body pressing block is arranged between the two magnets. The main body component is provided with a lower magnetic body connected with the two magnets by a magnetic clutch, and the lower part of the magnetic clutch is provided with a conductive piece. Both ends of the conductive piece are provided with silver chromium oxide upper contacting points, and both of each magnetic clutch are provided with magnetic body fixing folding hems. The main body component is sealed in a main body chamber filled with nitrogen. The sealed and magnetic explosion and water preventing seesaw type power supply switch has the advantages of economy, practicality and safety and is suitable for a power supply switch for indoor illumination and electric control apparatus of industrial and mining enterprises.
Description
The utility model relates to mains switch, relates in particular to the explosion-proof waterproof seesaw type power switch of closed type magnetic.
The tradition seesaw type switch is to control the motion of carrying object with spring as swinging actuating rod, and long-term use meeting is along with the variation and the distortion of the elastic coefficient cause the switch swing not normal.The carrying object of seesaw type switch is directly exposed in the air contact arc in can't the spacing contact course of work, does not possess waterproof and explosion-proof function.And use back contact to lose efficacy for a long time because of arcing area carbon causes connecting and disconnecting of the circuit.The external magnetic type switch, magnet comes off easily, and explosion-proof performance is undesirable.
The purpose of this utility model provides the explosion-proof waterproof seesaw type power switch of a kind of economical and practical, safe and reliable closed type magnetic.
The utility model is taked following measures in order to achieve the above object, and the explosion-proof waterproof seesaw type power switch of closed type magnetic comprises switch case, and switch case top is provided with the seesaw type button; The middle part is provided with body assembly; The bottom is provided with connector assembly; The see-saw type button is provided with the button shell, and its inside is provided with upper magnet, grips by magnetic to connect two blocks of different magnet of upper magnet polarity; Body assembly is set magnet, grip two blocks of different magnet of connection lower magnet polarity by magnetic, magnetic is gripped the bottom and is provided with conducting strip, its two ends are respectively equipped with the common formation of silver-colored chromium oxide upper contact seesaw down, join with corresponding silver-colored chromium oxide lower contact of upper contact and connector assembly, conducting strip is by seesaw rotating shaft conducting rod and connector assembly join down, feature is to be provided with the trapezoidal magnet compact heap between two blocks of magnet of seesaw type button, and fix with screw and fixture, body assembly magnetic is gripped two ends and is provided with fixedly flanging of magnet, and body assembly is sealed in the main cavity of switch case of inflated with nitrogen.
The utility model is that the characteristics of utilizing the magnetic power of permanent magnet to penetrate engineering plastics adopt two seesaw structures the current-carrying seesaw all to be sealed in the plastic chamber that fills nitrogen, by the outer seesaw type button swing of annular seal space control indirectly cavity contain flow seesaw (following seesaw) thus the swing purpose that reaches the button electric current of make-and-break have waterproof, explosion-proof, the function of preventing the contact carbon distribution.Owing to adopt high-throughout permanent magnetic material (alumal or Ferrite Material) magnetic flux density big, increased the contact pressure of contact, reduced contact resistance, make it to adapt to the control of big electric current, economical and practical, safe and reliable, be applicable to that room lighting is with mains switch and industrial and mining enterprises' electrical control gear.
Elaborate below in conjunction with accompanying drawing:
Accompanying drawing is the explosion-proof waterproof seesaw type power switch of a closed type magnetic structural representation.
The explosion-proof waterproof seesaw type power switch of closed type magnetic comprises switch case 4, and switch case top is provided with the seesaw type button; The middle part is provided with body assembly; The bottom is provided with connector assembly; The see-saw type button is provided with button shell 1, and its inside is provided with upper magnet, grips 21 by magnetic and connects the different two blocks of magnet 2,20 of upper magnet polarity; Body assembly is set magnet, grip 6 by magnetic and connect two blocks of different magnet 5 of lower magnet polarity, 19, magnetic is gripped the bottom and is provided with conducting strip 7, its two ends are respectively equipped with silver-colored chromium oxide upper contact 8,18 common formations are seesaw down, with the corresponding silver-colored chromium oxide lower contact 10 of upper contact, 17 join with connector assembly, conducting strip is by seesaw rotating shaft conducting rod and connector assembly join down, be provided with trapezoidal magnet compact heap 3 between two blocks of magnet of seesaw type button, and it is fixing with screw and button housing mount 22, body assembly magnetic is gripped two ends and is provided with fixedly flanging of magnet, and body assembly is sealed in the main cavity of switch case of inflated with nitrogen.The material of switch case and shift knob shell adopts high flame retardant, high-intensity polycarbonate.
The conventional switch connector assembly be with screw as the line ball securing member, contact area is little, installation is inconvenient, the rapid wear lead, the utility model need not screw, only needs that lead is directly inserted wiring hole and has promptly finished whole wiring process.The line ball folder that three groups of high-strength spring steels are made is housed in the utility model connector assembly, and 11,15,16 line balls folder closely contacts with the lead that inserts, and is difficult for loosening. Loose ends button 12,13,14 is housed in connector assembly bottom to be pushed this button the displacement of line ball folder can be transferred to lead from wiring hole smoothly.
