Abstract
The utility model discloses an electromagnetic relay movable contact spring structure, including the flexure strip, the up end of flexure strip upwards is the arch, the middle part of flexure strip is equipped with the contact hole with electromagnetic relay armature contact matched with, both sides are equipped with horizontal limiting plate around the hole of contact, the flexure strip left end is equipped with the downwarping and becomes curved connecting plate, the left end face of connecting plate is equipped with the terminal pin of level and interval setting, the inner wall of terminal pin opposite face is equipped with the semicircular buckle, connecting plate left end face between the terminal pin is equipped with the cutting, the front end of transplanting a cutting is equipped with the anticreep tooth of arrow point shape. The utility model discloses structural design is novel, can be fast inserts the installation and can guarantee installation back fastness and stability through inlaying, simultaneously, has stronger mechanical properties, has prolonged life.
Description
Technical field
The utility model relates to electromagnetic relay field, particularly relates to a kind of electromagnetic relay movable contact spring structure.
Background technology
Dynamic and the static contact spring piece of the coil of electromagnetic relay input, yoke, division board, base plate, iron core, armature, output.When coil adds certain voltage or electric current at the two ends of its terminal pin, the coil of energising will produce magnetic flux, magnetic flux is lost by iron core, yoke, armature and certain working gas gap produce attraction, thus drive movable contact spring to connect break-make and conversion that static contact spring piece carrys out realizing circuit.
The mechanical strength of the movable contact spring of electromagnetic relay is in the market poor, easily towards armature curving in Long-Time Service process, causes and cannot normally work; In addition, movable contact spring adopts some glue to ensure its fixing fastness after mostly adopting intercalation after installing on casing of relay again, and install loaded down with trivial details losing time, easy contact movable contact spring loosens and causes loose contact.
Utility model content
For solving prior art Problems existing, the purpose of this utility model is to provide a kind of electromagnetic relay movable contact spring structure, and novel in structural design, is convenient to Fast Installation, and simultaneously in Long-Time Service process, bending phenomenon occurs for mechanical strength height.
The technical solution of the utility model is as follows:
Electromagnetic relay movable contact spring structure, it is characterized in that: comprise flexure strip, the upper surface of flexure strip is upwards in arch, the middle part of flexure strip is provided with the contact holes matched with electromagnetic relay armature contact, before and after contact holes, both sides are provided with horizontal limiting plate, described flexure strip left end is provided with the connecting plate being bent downwardly camber, the left side of connecting plate is provided with level and spaced terminal pins, the inwall of terminal pins opposite face is provided with semicircular buckle, connecting plate left side between terminal pins is provided with cutting, and cutting front end is provided with sagittate anticreep tooth.
Described electromagnetic relay movable contact spring structure, is characterized in that: described contact holes can be through hole or blind hole, and contact holes is generally bellmouth, and the cone end of bellmouth upward.
Advantage of the present utility model:
The utility model novel in structural design, can install quickly through intercalation and can ensure to install rear fastness and stability, meanwhile, have stronger mechanical performance, extend useful life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1:
Electromagnetic relay movable contact spring structure, comprise flexure strip 1, the upper surface of flexure strip 1 is upwards in arch, the middle part of flexure strip 1 is provided with the contact holes 2 matched with electromagnetic relay armature contact, before and after contact holes 2, both sides are provided with horizontal limiting plate 3, can effectively prevent from armature contact from contacting too cross section with contact holes not easily to separate, flexure strip 1 left end is provided with the connecting plate 4 being bent downwardly camber, the left side of connecting plate 4 is provided with level and spaced terminal pins 5, the inwall of terminal pins 5 opposite face is provided with semicircular buckle 6, connecting plate left side between terminal pins 5 is provided with cutting 7, cutting 7 front end is provided with sagittate anticreep tooth 8.
Contact holes 2 can be through hole or blind hole, and contact holes 2 is generally bellmouth, and the cone end of bellmouth upward.
Cooperatively interact between the anticreep tooth 8 of two buckles 6 of the present utility model, cutting front end, when on the shell body being arranged on electromagnetic relay, can ensure fixing after fastness and stability.
