In vacuum interrupter (1) cavity, in the middle of front, conduction seesaw seat (12) is housed, conduction seesaw seat (12) is supported on the middle part of conduction seesaw (10), electrician's iron (13) (13 ') is inlayed at the two ends, front of conduction seesaw (10) respectively, moving contact (9) is inlayed in one end, the back side of conduction seesaw (10), and other end welding is flexible coupling (11); Lower connecting terminal (6) is equipped with in one end of vacuum interrupter (1), one end of lower connecting terminal (6) is fixed on mount pad (3), the other end puts in vacuum interrupter (1), fixed contact (8) is inlayed in the position of corresponding moving contact (9), the other end of vacuum interrupter (1) is upper connecting terminal (7), one end of upper connecting terminal (7) is fixed on mount pad (3), and the other end puts in welding in vacuum interrupter (1) and is flexible coupling (11).
The present invention can be widely used in the mains switch of the civil electric appliance of family, office, hotel, restaurant, market, hospital etc., its structure can make wall type installation in addition, also hand-hold type or portable structure can be made, be applied to industrial enterprise as hand-held mains switch or control button use, be particularly suitable for inflammable, the explosive places such as chemical industry, coal, iron and steel.
The invention has the advantages that: safe and reliable, volume is little, structure is simple, explosion-proof performance is good, serviceability is stable.
Accompanying drawing explanation
Fig. 1 is the longitudinal sectional view that the present invention makes wall type mounting structure;
Fig. 2 is the longitudinal sectional view that the present invention makes handheld structure.
In figure: 1 vacuum interrupter, 2 permanent magnets, 3 mount pads, 4 seesaw buttons, 5 panels, 6 lower connecting terminals, 7 upper connecting terminals, 8 fixed contacts, 9 moving contacts, 10 conduction seesaws, 11 are flexible coupling, 12 conduction seesaw seats, 13,13 ' electrician's iron, 14 limiting buffer seats, 15 button limiting stands.
Embodiment
The present invention is further described with reference to the accompanying drawings.The present invention forms primarily of vacuum interrupter (1), permanent magnet (2), mount pad (3) and seesaw button (4).Vacuum interrupter (1) shell adopts glass tube or earthenware to make, and the lower connecting terminal (6) at vacuum interrupter (1) two ends and upper connecting terminal (7) and the seesaw (10) that conducts electricity all adopt oxygen-free copper punch forming.Fixed contact (8) is inlayed in vacuum tube the inner of lower connecting terminal (6), vacuum tube the inner welding of upper connecting terminal (7) is flexible coupling (11), be flexible coupling (11) the other end with conduction seesaw (10) weld together, the other end of conduction seesaw (10) inlays moving contact (9) in the position of corresponding fixed contact (8), the front, two ends of conduction seesaw (10) inlays electrician's iron (13) and (13 ') respectively, electrician's iron can adopt silicon steel replace but can not adopt carbon steel, to avoid magnetization phenomenon, fixed contact (8) and moving contact (9) adopt chromiumcopper to make, in vacuum interrupter (1) cavity, conduction seesaw seat (12) is equipped with in centre position, front, conduction seesaw seat (12) is supported on the middle part of conduction seesaw (10), conduction seesaw (10) welding be flexible coupling (11) one end after a bonding limiting buffer seat (14) on tube wall, what make fixed contact (8) and moving contact (9) opens apart from about 2 ~ 3mm, and the material that limiting buffer seat (14) can adopt stainless steel wire etc. to have certain temperature capacity and toughness makes.When the shell of vacuum interrupter (1) adopts glass tube to make, first by firm for fixing for lower connecting terminal (6) melting welding, again by the conduction seesaw seat (12) assembled, conduction seesaw (10), connect be flexible coupling (11), upper connecting terminal (7) and limiting buffer seat (14) and fix on glass tube inwall, evenly heat rapidly in border, glass tube welding position after glass tube is vacuumized, due to the suction function in pipe, the copper body of softening glass tube and upper connecting terminal (7) is welded together; When shell as vacuum interrupter (1) adopts earthenware to make, the both ends of the surface of earthenware are carried out high temperature metallization process after grinding, refills and prepare pipe inner part, in vacuum seal stove, carry out air-tightness welding with yellow gold.Mount pad (3) adopts the disposable die casting moulding of electrician's bakelite material, the two side of mount pad (3) there is the button limiting stand (15) of respective protrusions produce mechanical damage to prevent seesaw button (4) from encountering vacuum interrupter (1), the scope of activities of permanent magnet (2) is greater than more than 1 times of conduction seesaw (10) scope of activities, in order to avoid form the movable dead point of conduction seesaw (10).Seesaw button (4) also adopts electrician's bakelite material die casting moulding, puts permanent magnet (2) disposable die casting moulding before casting pressure in its inside, back side.First vacuum interrupter (1) is installed on mount pad (3) base plate during assembling, can carry out cementing if desired, or by resin material sealing on mount pad (3), again seesaw button (4) is installed in the middle of the two side of mount pad (3), covers panel (5) and namely complete assembling.The contour structures of mount pad (3) and panel (5) can be made into wall type or hand-hold type, the structure such as portable according to requirements.
The part upper end of seesaw button (4) being projected on panel during combined floodgate is pressed, permanent magnet (2) upper end is close to electrician's iron (13 '), be rapidly to centre under the influence of a magnetic field to draw close, seesaw button (4) stops mobile under the effect of button limiting stand (15), the upper end of electrician's iron (13 ') band moving conductive seesaw (10) moves forward, one end that the seesaw (10) that conducts electricity under the effect of conduction seesaw seat (12) is inlaid with moving contact (9) is moved backward, close with fixed contact (8) and stop having moved making process after applying certain pressure.
The part lower end of seesaw button (4) being projected on panel during separating brake is pressed, permanent magnet (2) upper end is away from electrician's iron (13 '), lower end is close to electrician's iron (13) simultaneously, when after the distance that its distance is less than permanent magnet (2) upper end and electrician's iron (13 '), be rapidly to centre under the influence of a magnetic field to draw close, seesaw button (4) stops mobile under the effect of button limiting stand (15), the lower end of electrician's iron (13) band moving conductive seesaw (10) moves forward, pressure now between dynamic/static contact reduces, contact area reduces, resistance strengthens, current density increases, in vacuum interrupter (1), produce metallic vapour form vacuum arc.Due to permanent magnet (2) lower end, close to electrician's iron (13), both are close rapidly under the influence of a magnetic field further, and the distance of dynamic/static contact is pulled open rapidly and the mistake nought state of electric current, and electric arc extinguishes instantaneously, and dielectric strength is recovered immediately.
