Present employed normally closed quick-action switch, simulation moving contact material is fine copper T2, and simulation fixed contact material is brass H62, and the product processing cost is higher; During switch motion, guide rod acts on the disjunction reed, and the disjunction reed drives double-bridge structure and moves, and the moving contact and the fixed contact that are in closure state are broken off, and makes the simulation moving contact that is in off-state closed with the simulation fixed contact simultaneously; In actual use; The fixed contact in normally closed loop is connected with the Be Controlled loop in the normally closed quick-action switch; The fixed contact of another group simulated action is not connected with external circuitry, but in course of action, the simulation moving contact of link circuit is not because of a large amount of metallic copper powder occurring with simulation fixed contact mechanical wear; And attached in the quick-action switch working chamber and the surface of working contact; Directly cause the degree of protection of quick-action switch product not up to standard, characteristics such as insulation resistance, industrial frequency withstand voltage lost efficacy defective, had reduced reliability of products.
The utility model content
The purpose of the utility model is to provide a kind of designs simplification, and cost is low, the doube bridge double break point magnetic quenching sealed type quick-action switch that reliability is high.
For achieving the above object, the utility model has adopted following technical scheme:
Comprise housing and be arranged at the double-bridge structure in the housing that be provided with guide rod in the said double-bridge structure, an end of guide rod stretches out housing; The other end links to each other with retracting spring in being arranged at housing; Be provided with the disjunction reed in the housing, an end of disjunction reed links to each other with guide rod, and the other end links to each other with double-bridge structure; Said double-bridge structure comprises work moving contact and simulation moving contact bridge, and the work moving contact a pair of fixed contact interior with being arranged at housing contacts.
Be provided with rotary minute fault block in the said housing, divide an end of fault block to match with guide rod, the other end matches with the work moving contact.
Said housing is provided with magnet steel.
Said housing comprises cap and with at the bottom of the shell that cap links to each other, guide rod links to each other with the depression bar assembly that is arranged at the cap outside, and guide rod is provided with the sealing cap that links to each other with cap.
Be provided with the U shape die cavity that limits simulation moving contact bridge shift position in the said housing.
The material of said simulation moving contact bridge is a tin bronze.
The said doube bridge double break point of the utility model magnetic quenching sealed type quick-action switch employing work moving contact is formed double-bridge structure with simulation moving contact bridge; Only have in the housing with double-bridge structure in the static contact structure that cooperates of work moving contact; Not only satisfied in the real work switch control to normally closed loop; And reduced contact material use, simplified the internal structure of quick-action switch, improved the reliability of quick-action switch.
Description of drawings
Fig. 1 is one of structural representation of the utility model;
Fig. 2 be the utility model structural representation two;
Among the figure: depression bar assembly 1, magnet steel 2, at the bottom of the shell 3, cap 4, fixed contact 5, work moving contact 6, simulation moving contact bridge 7, U shape die cavity 8, guide rod 9, sealing cap 10, disjunction reed 11 divides fault block 12, retracting spring 13.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1 and Fig. 2, this use is novel to be comprised housing and is arranged at the double-bridge structure in the housing, is provided with guide rod 9 in the said double-bridge structure; One end of guide rod 9 stretches out housing, and the other end links to each other with retracting spring 13 in being arranged at housing, is provided with disjunction reed 11 in the housing; One end of disjunction reed 11 links to each other with guide rod 9, and the other end links to each other with double-bridge structure, and said double-bridge structure comprises work moving contact 6 and the simulation moving contact bridge 7 that links to each other with work moving contact 6; The material of said simulation moving contact bridge 7 is a tin bronze; The work moving contact 6 a pair of fixed contact 5 interior with being arranged at housing contacts, and is provided with rotary minute fault block 12 in the said housing, divides an end of fault block 12 to match with guide rod 9; The other end matches with work moving contact 6; Said housing is provided with magnet steel 2, is provided with the U shape die cavity 8 that limits simulation moving contact bridge 7 shift positions in the said housing, and said housing comprises cap 4 and with at the bottom of the shell that cap 4 links to each other 3; Guide rod 9 links to each other with the depression bar assembly 1 that is arranged at cap 4 outsides, and guide rod 9 is provided with the sealing cap 10 that links to each other with cap 4.
During use, apply power, depression bar components drive guide rod compression retracting spring to the depression bar assembly; Guide rod presses down and makes the disjunction reed reach quick upturned position, drives double-bridge structure in the switching process of disjunction reed and moves upward, the action of work moving contact; Work moving contact and fixed contact break off, and simultaneously, press down in the process at guide rod; Guide rod presses the branch fault block, divides fault block to rotate to force to divide the breakpoint moving contact action that pushes the work forward, and has realized the moving contact and fixed contact pressure disjunction in normally closed loop; Direction initialization moves rapidly and breaks off the electric arc that produces during disconnection in magnet steel magnetic field force effect lower edge, has reduced the scaling loss of electric arc to the working contact surface, and U shape die cavity is as analog contacts; Cooperate with simulation moving contact bridge, play position-limiting action, guaranteed that distance is opened in the design of working contact action; And make normally closed quick-action switch switch inner chamber no dust pollution in actual use, characteristics such as insulation resistance, industrial frequency withstand voltage can satisfy the design instructions for use, promoted reliability of products.
