As shown in Figures 4 to 6, moving contact 120 is arranged in the two arms 111 of positioner 110 by the rectangular indexing holes of position, intermediate portion, and is supported on the surface 101 and 103 of contact holding components 100; Arc angle 140 and elastic component 130 are arranged in the two arms 111 of positioner 110 by the rectangular indexing holes of their middle parts successively, and on the surface 101 and 103 being cooperatively supported on contact holding components 100 with moving contact 120 (wherein, arc angle 140 is pressed on moving contact 120, and elastic component 130 is pressed in arc angle 140); The axle 112 across two arms 111 of positioner 110 is pressed on elastic component 130, to limit the position of moving contact 120, arc angle 140 and elastic component 130, makes them can not from the upper end slippage of the two arms 111 of positioner 110; Simultaneously, moving contact 160, arc angle 170 and elastic component 150 are supported on the surface 102 of contact holding components 100, the axle 112 of positioner 110 is pressed on elastic component 150 to limit the position (because moving contact 160, arc angle 170 and elastic component 150 are not arranged in the two arms 111 of positioner 110, so their middle part does not have rectangular indexing holes) of moving contact 160, arc angle 170 and elastic component 150.
As shown in Figure 5, moving contact 120 is bridge shape moving contact, (namely its front and back position is symmetrically arranged with contact 122 and contact 123, the pier location of former and later two symmetries is respectively arranged with contact 122 and contact 123), mid portion is the location structure 121 (being a rectangular opening) of moving contact 120, and the rectangular opening that the one arm 111 of positioner 110 passes the middle part of moving contact 120 is that moving contact 120 is located and leads.It is to be understood that moving contact 160 has the structure (except intermediate position do not arranged location structure except) similar to moving contact 120.
As shown in Figure 6, contact system according to a first embodiment of the present invention comprises moving contact subsystem and single fixed contact 180.Particularly, moving contact subsystem comprise contact holding components 100, positioner 110, be each passed through the two arms 111 of positioner 110 two moving contacts 120 and on arc angle 140 and elastic component 130 and between the two arms 111 of positioner 110 and with moving contact 120 (and on arc angle 140 and elastic component 130) parallel arranged moving contact 160 and on arc angle 170 and elastic component 150.
Composition graphs 2, Fig. 4, Fig. 6 and Fig. 7 can be found out, the plane 101 of contact holding components 100 and plane 103 support moving contact 120 and arc angle 140 thereof and elastic component 130, and the plane 102 of contact holding components 100 supports moving contact 160 and arc angle 170 thereof and elastic component 150; The middle part of moving contact 120, elastic component 130 and arc angle 140 is provided with rectangular indexing holes, and this some holes is each passed through two arms 111 of positioner 110; Axle 112 across the two arms 111 of positioner 110 is pressed on elastic component 130 and elastic component 150; Three moving contacts supported by three planes 101,102 and 103 of contact holding components 100 are respectively by the two arms 111 of positioner 110 and the step 104 of contact holding components 100 and the common guiding of step 105 and locate; Plane 102 due to contact holding components 100 1mm lower than the position of plane 101 and plane 103, so the 1mm lower than the moving contact 120 in the plane 101 being positioned at contact holding components 100 and plane 103 that be positioned at moving contact 160 in the plane 102 of contact holding components 100.
As can be seen from Figures 6 and 7, fixed contact 180 in contact system according to a first embodiment of the present invention has contact (altogether six contacts) corresponding with two contacts of moving contact 120 and two contacts of moving contact 160 respectively, and these six contacts are in the same plane and highly consistent; Due to the 1mm lower than the position of the moving contact 120 in the plane 101 being positioned at contact holding components 100 and plane 103 that be positioned at moving contact 160 in the plane 102 of contact holding components 100, and all contact heights of fixed contact 180 are consistent, so be positioned at moving contact 160 in the plane 102 of contact holding components 100 than the moving contact 120 in the plane 101 being positioned at contact holding components 100 and plane 103 open apart from little 1mm, be arcing contact.Contact corresponding with the contact of moving contact 120 on the contact of contact moving contact 120 compared with contact corresponding with the contact of moving contact 160 on fixed contact of moving contact 160 and/or fixed contact, adopts the material that high, the resistance to electric arc ability of resistivity is strong.Such as, the contact of moving contact 160 adopts silver-tungsten alloy, and contact corresponding with it on fixed contact adopts silver-diamondite, and other all contacts all adopt silver-tin alloy (or silver-cadmium oxide alloy).Certainly, it may occur to persons skilled in the art that, moving contact 120 and 160 also can adopt the contact of identical material, and contact corresponding with the contact of moving contact 120 and 160 on fixed contact also can adopt identical material.
Particularly, contact closure process in contact system shown in Fig. 6 and Fig. 7 is as follows: when contact holding components 100 drives moving contact 160 and two moving contacts 120 move downward, open and close prior to two moving contacts 120 and fixed contact 180 apart from less moving contact 160 (that is, arcing contact); When two moving contacts 120 not yet close with fixed contact 180, moving contact 160 (that is, arcing contact) closes with fixed contact 180, all electric currents all concentrate on moving contact 160 (that is, arcing contact); When contact holding components 100 continues to move downward certain distance after moving contact 160 and fixed contact 180 are closed, moving contact 160 and two moving contacts 120 all close with fixed contact 180, electric current is shared on each moving contact, and circuit starts normally, making current evenly; Now, moving contact 160 and two moving contacts 120 are connected simultaneously, and moving contact 120 and the contact resistance between moving contact 160 and fixed contact 180 reduce, thus can reduce the temperature rise of contact system.It is clearly understood that, because contact resistance rate corresponding with it on the contact of moving contact 160 and fixed contact 180 is higher than the contact on the fixed contact 180 of the contact of moving contact 120 and correspondence with it, so, now share electric current on each moving contact and unequal, electric current on moving contact 160 is significantly less than other two moving contacts 120, and contactor mainly conducts electricity by two moving contacts 120.
In addition, it is as follows that contact in contact system shown in Fig. 6 and Fig. 7 disconnects process: when contact holding components 100 drives two moving contacts 120 and moving contact 160 to move upward, open and disconnect in two moving contacts 120 and fixed contact 180 after less moving contact 160 (that is, arcing contact); When moving contact 120 and fixed contact 180 disconnect, moving contact 160 (that is, arcing contact) does not disconnect with fixed contact 180, all electric currents all concentrate on moving contact 160 (that is, arcing contact); Two moving contacts 120 do not have breaking current when disconnecting with fixed contact 180, therefore do not have electric arc; When contact holding components 100 continue motion moving contact 160 (that is, arcing contact) also will be disconnected with fixed contact 180 time, all electric currents are accumulated in the upper disjunction of moving contact 160 (that is, arcing contact), just produce electric arc; Electric arc is by arc quenching system by after arc extinguishing, and circuit is disconnected completely.Now, protect other two moving contacts 120 while the electrical arc erosion moving contact 160 (that is, arcing contact) produced when moving contact 160 disconnects with fixed contact 180 substantially not by scaling loss, therefore can improve the electrical endurance of contact system.In addition, contact corresponding with it on the contact of moving contact 160 and fixed contact 180 have employed the higher and material that resistance to electric arc ability is stronger of resistivity (such as, be respectively silver-tungsten alloy and silver-diamondite), so their resistance to electric arc ability is strong, thus the electric life of moving contact 160 (that is, arcing contact) can be improved.
Fig. 8 is the schematic diagram of the contactor of the contact system adopted according to a first embodiment of the present invention.As shown in Figure 8, adopt that the contactor volume of contact system is according to a first embodiment of the present invention little and capacity is large.
Particularly, when the control coil energising of contactor, according to maxwell's electromagnetic principle, under the excitatory effect that control coil produces, between dynamic iron core and fixed core, produce electromagnetic attraction, the counter-force that dynamic iron core overcomes reaction spring moves downward, and band moving contact holding components 100 moves downward; Contact holding components 100 drives moving contact 120 and 160 to move downward, and moving contact 160 (that is, arcing contact) is first contacted with fixed contact 180; After contact holding components 100 continues to move downward 1mm, moving contact 160 and the contact resistance between two moving contacts 120 and fixed contact 180 reduce; Contact holding components 100 continues to move downward certain distance, until dynamic iron core, fixed core are completely closed, completes contact closure process.Circuit connected by above process implementation contactor, makes electric equipment (such as, motor etc.) realize the function of energising running.
Particularly, when the control coil dead electricity of contactor, according to maxwell's electromagnetic principle, the excitatory disappearance of control coil, electromagnetic attraction between dynamic iron core and fixed core disappears, dynamic unshakable in one's determination under reaction spring effect, promote contact holding components 100 and move upward, first two moving contacts 120 and fixed contact 180 are disconnected; Now, open the less moving contact 160 (that is, arcing contact) of distance and be still in closure state with fixed contact 180; Contact holding components 100 continues to move upward after 1mm, opens and just disconnects with fixed contact 180 apart from less moving contact 160 (that is, arcing contact), now produce electric arc; Apart from less moving contact 160 (arcing contact) and fixed contact 180, electric arc is introduced arc extinguishing in arc quenching system by opening; Contact holding components 100 continues the certain distance (clearance between open contacts) that moves upward, until dynamic iron core, fixed core are opened completely.After completing contact disconnection process, contact system is in the open position shown in Fig. 6.First two moving contacts 120 disconnect with fixed contact 180 in the above process, but open and be still in closure state apart from less moving contact 160 and fixed contact 180, all electric currents by moving contact 160, without electric arc when therefore two moving contacts 120 disconnect with fixed contact 180; Contact holding components 100 continues to move upward, and produce electric arc when moving contact 160 and fixed contact 180 disconnect, moving contact 160 is arcing contact, and two moving contacts 120 are not burnt, thus improve the electrical endurance of contact system.Above process implementation contactor divides deenergizing, the function making electric equipment (such as, motor etc.) realize power-off to stop.
Should be understood that positioner 110 can have two arms, is the structure of " U " font, " twenty " font; Also can have the arm of more than three, be the structure etc. of " mountain " font, " thirty " font.In addition, the rectangular indexing holes of the middle part of moving contact 120, arc angle 140 and elastic component 130 can by circle, ellipse, L-type, T-shaped, the replacement such as Y type, triangle, polygon, special-shaped location structure, as long as moving contact 120, arc angle 140 and elastic component 130 can be arranged on the one arm of positioner 110 movably.
Fig. 9 is the assembling schematic diagram of contact system according to a second embodiment of the present invention.As shown in Figure 9, this contact system comprises 5 moving contacts (being two moving contacts 160 in outermost two moving contacts 120, middle moving contact 200 and secondary outside respectively) and single fixed contact 180.Wherein, two moving contacts 160 in middle moving contact 200 and time outside are disposed with arc angle and the elastic component that middle part does not have location structure, and the arc angle that outermost two moving contacts 120 and top thereof set gradually and elastic component are arranged in the two arms 111 of positioner 110 by the location structure of their middle parts.Wherein, the contact position height of five moving contacts 120,200,160 is consistent, but the contact position of middle moving contact 200 is more farther apart from their middle part than the contact position of moving contact 120 and moving contact 160, fixed contact 180 is provided with contact at five moving contact contact correspondence positions respectively, and the fixed contact of middle moving contact 200 correspondence is higher than other four fixed contact 1.5mm.Now, middle moving contact 200 is opened apart from little 1.5mm than two moving contacts 160 in outermost two moving contacts 120 and time outside, and middle moving contact 170 is arcing contact.Here moving contact 120 and 160 is the moving contact 120 and 160 that above composition graphs 4-7 describes, and moving contact 200 has the structure (except moving contact 200 is longer than moving contact 160) similar to moving contact 160.
The operation principle of the contact system shown in Fig. 9 and above for contact system according to a first embodiment of the present invention describe similar, so be not repeated at this.
Contact system according to the embodiment of the present invention is compared with contactor with existing contact system with contactor, positioned owing to having two moving contacts in contact system at least by least two arms of positioner and led, so saved space, thus the volume of same current class product is made to be far smaller than existing products in markets.
In addition, compare the contact system with single moving contact according to the contact system comprising multiple moving contact of the embodiment of the present invention and greatly reduce contact resistance, thus the temperature rise of contact system can be reduced.Moreover, by arrange multiple moving contacts that contact system comprises different time to close with fixed contact and/or to disconnect, to reduce when contact system closes or disconnects electric arc to the scaling loss of moving contact, thus improve the electrical endurance of contact system.
