Abstract
The utility model discloses a push piece improved electromagnetic relay, comprising a skeleton, a yoke, a dynamic leaf spring mechanism and a static leaf spring mechanism fixed on the base, a push piece and a pull-out piece spring and as well as a casing. A baffle made of insulating material perpendicular with and fixed on the push piece is arranged on either side of the direction that the push piece closes with the dynamic leaf spring mechanism. The push piece improved electromagnetic relay has the advantages of reasonable design, simple structure, easy fabrication, low defective rate and low cost, high pressure resistance and enough creepage distance; and the utility model is applicable to all electromagnetic relay and has high value of promotion.
Description
Technical field
The improved electromagnetic relay of a kind of push jack
Background technology
In every places that needs the circuit conversion function such as communication apparatus, automatics, household electrical appliance, auto electroincs, all may use relay.Push jack is as a subsystem in the relay drive system, be connected with reed armature yoke, be a critical component of the withstand voltage height of decision product, the relay that uses on the market often is subjected to the restriction in space, between coil and the static contact spring piece along the distance on insulating material surface weak point be that creepage distance is short, it is withstand voltage to promote product, can not meet customer need, and perhaps cost is too high, cost an arm and a leg, market potential is limited.Simultaneously structurally, the connection of push jack is unreliable, push jack can occur and drop, and causes normally making useful.
Summary of the invention
The design of the utility model by push jack provide a kind of simple in structure, make easily, the electromagnetic relay of cost is low, height is withstand voltage and enough creepage distance.On push jack connected, line bag side adopted pedestal U type location, on snap in armature again, make fully and located, tip side adopts and snaps in reed, makes push jack not drop in motion process, increases reliability of products.
The improved electromagnetic relay of a kind of push jack, by skeleton, yoke, be fixed in sound reed mechanism, push jack and making leaf spring on the pedestal, and shell forms, and push jack is respectively equipped with vertical near the direction both sides of movable contact spring mechanism and is fixed in baffle plate on the push jack.
Baffle plate is made by insulating material.
Be respectively equipped with baffle plate at push jack near the direction both sides of movable contact spring mechanism, the creepage distance that can increase by two electric conductors be between coil and the static contact spring piece along the distance on insulating material surface, and then improve the withstand voltage properties of product.
The utility model is reasonable in design, and is simple in structure, makes easily, and defect rate is low and cost is low, high withstand voltage, and enough creepage distances are arranged, and suits to implement to use on all electromagnetic relays, and promotional value is widely arranged.
Description of drawings
Accompanying drawing 1 is an installation diagram of the present utility model, also is Figure of abstract of the present utility model.
Accompanying drawing 2 is a general assembly drawing of the present utility model;
Accompanying drawing 3 is the structural representation of push jack;
Each label is respectively among the figure: 1, shell, 2, armature, 3, yoke, 4, push jack, 5, movable contact spring mechanism, 6, static contact spring piece mechanism, 7, skeleton, 8, making leaf spring, 9, pedestal, 10, right baffle-plate, 11, right baffle plate, 12, coil.
Embodiment
Provide an embodiment below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment:
With coil power is that 0.45 watt electromagnetic relay is an example, referring to Fig. 3, and length and width, the thick 5mm that is respectively, 3mm, it is 2.5mm that the both sides on the push jack 4 of 0.3mm are respectively equipped with upper base, goes to the bottom to be 4mm, the ladder height is 1.7mm, and thickness is right baffle-plate 10 and the right baffle plate 11 made by insulating material of 0.3mm.Because the existence of right baffle-plate 10 and right baffle plate 11, the distance along the insulating material surface between coil 12 and the movable contact spring mechanism 5 increases, thereby improves the withstand voltage properties of product.
Claims (2)
1, the improved electromagnetic relay of a kind of push jack, by skeleton, yoke, be fixed in sound reed mechanism, push jack and making leaf spring on the pedestal, and shell forms, and it is characterized in that: push jack is respectively equipped with vertical near the direction both sides of movable contact spring mechanism and is fixed in baffle plate on the push jack.
2, the improved electromagnetic relay of push jack according to claim 1, it is characterized in that: described baffle plate is made by insulating material.
