Description
Technical field
The utility model belongs to the appliance switch technology, relates to a kind of closed travel switch.
Background technology
Movable contact bridge and the moving contact that existing travel switch generally comprises the push rod that is installed in the housing, be connected with push rod by reed, be fixed on the parts such as fixed contact on the housing, because the bonding conductor of push rod and fixed contact must stretch out housing, often causing inside and outside the housing can not positiver sealing, make that the class of insulation of travel switch is lower, be difficult to be applicable to open air and moist place.In addition, common travel switch exists mostly also that electric arc is big, contact easy-sintering, contact oxidation and cause defective such as loose contact, has influenced the dependability of product.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of rational in infrastructure, good airproof performance, closed travel switch that dependability is high are provided.
Closed travel switch of the present utility model includes a housing, in housing, be provided with a push rod and the movable contact bridge that is connected with push rod by reed, the two ends, the left and right sides of movable contact bridge are two pairs of moving contacts, a pair of fixed contact and a pair of fixed contact down gone up that being respectively arranged with up and down of moving contact cooperates with moving contact, upper and lower fixed contact is connected with bonding conductor respectively, housing is stretched out in the upper end of push rod, and the bonding conductor lower end is also stretched out housing and constituted terminals; Described housing inner chamber is divided into two parts of separating up and down, the top of inner chamber is working chamber, push rod, reed, movable contact bridge, last fixed contact and following fixed contact are installed in the working chamber, the bottom of inner chamber is an annular seal space, the bonding conductor that is connected with upper and lower fixed contact all passes annular seal space and stretches out from the housing lower end, be filled with encapsulant (as polyamine fat etc.) in the annular seal space, the bottom of housing is provided with gum-injecting port, and encapsulant promptly injects annular seal space from gum-injecting port.Described push rod upper end is stretched out between the outer surface of housing parts and the housing and is provided with sealing shroud.Described movable contact bridge below is provided with two seesaws, on the fulcrum support housing thereunder at seesaw middle part, seesaw withstands on the movable contact pars basilaris pontis near an end of contact, seesaw is positioned at the below of a step on the push rod near an end of push rod, thereby when push rod presses down, seesaw one end can be depressed, and the other end lifts, and then dynamic and static contact is forced separately by lifting the movable contact bridge.In addition, be provided with magnetic sheet, be used for assisting arc extinguishing in the corresponding position of hull outside and dynamic and static contact.
The utility model is rational in infrastructure, and its good airproof performance can be suitable for the occasion that is used for open air and humidity; The seesaw structure that is provided with in its housing can by the active force of push rod, make dynamic and static contact force to break when moving contact sticks together with fixed contact generation galvanic corrosion, has improved the dependability of switch; The outer magnetic sheet that is provided with of its housing, the electric arc that produces in the time of can opening and closing switch plays the effect of magnetic quenching, has also improved the dependability of switch.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, push rod 2 and the movable contact bridge 4 that is connected with push rod by reed 3 are installed in the working chamber 11 on housing 1 top of closed travel switch of the present utility model, the movable contact bridge is provided with the moving contact 7 that cooperates with last fixed contact 5 and following fixed contact 6.The bonding conductor 8 that is connected on the upper and lower stationary contact passes the annular seal space 12 of lower housing portion, and stretches out housing formation terminals 81.The annular seal space lower end is provided with gum-injecting port 13, fills polyamine fat encapsulant 14 by gum-injecting port in annular seal space.Housing 1 is stretched out in the upper end of push rod, and is with the sealing shroud 21 of silastic material.Movable contact bridge below is provided with two seesaws 9, the fulcrum 91 of seesaw bottom for arching upward, and when push rod moved down, the step 22 on the push rod can press seesaw one end, made the seesaw other end that movable contact bridge 4 and moving contact 7 are forced to lift.The housing outer wall is provided with magnetic sheet 15, is used for carrying out magnetic quenching in switch deciliter process.
