Abstract
The utility model designs a kind of improved electric magnetic relay, comprise pedestal, iron core, coil, yoke, armature, movable contact spring and static contact spring piece, it is characterized in that: the body shape of movable contact spring is Back Word type, upper in Back Word type, lower two ends extend to form moving contact end and electric connecting terminal respectively, center line upper punch along movable contact spring between nearly moving contact end on the front of movable contact spring is pressed with a reinforcement, reinforcement half is in movable contact spring main body, reinforcement second half on moving contact end, the corresponding reinforcement position, the back side of movable contact spring forms groove, length and the width of the length of groove and width and reinforcement are consistent.The utility model has the advantages that the hardness adding movable contact spring before not affecting its material flexibility and be flexible under topic, solve domestic phosphorus brass material partially soft (as used ultrahard material, its pliability difference and shaping easy to crack) and the problem of fatigue resistance difference, through repetition test, the electrical endurance of product effectively can be improved.
Description
Technical field
The utility model relates to a kind of improved electric magnetic relay.
Background technology
Movable contact spring in present electromagnetic relay uses the import beryllium-bronze of 0.15mm thickness as moving plate material, and its advantage is good springiness, and fatigue resistance is strong.But material price is high, materials procurement is more difficult, and cost performance is without advantage.Therefore the product of electromagnetic relay generally adopts domestic phosphorus brass to be movable contact spring material at present, this material price cheaply and easily purchase, be used in relay product by wide model, its material behavior can meet the technical requirement of most of product, but on the product of some movable contact spring molding structure complexity, be movable contact spring material with phosphorus brass again, its elasticity and fatigue resistance cannot meet the requirement of product, cause produced product appliance life partially short.Therefore urgently the movable contact spring structure of existing electromagnetic relay is improved, to realize using cheap phosphorus brass for movable contact spring material.
Summary of the invention
The purpose of this utility model solves prior art repeat circuit product generally to adopt phosphorus brass the problems referred to above existing for movable contact spring material, provides a kind of improved electric magnetic relay.The utility model designs a kind of improved electric magnetic relay, comprise pedestal, iron core, coil, yoke, armature, movable contact spring and static contact spring piece, it is characterized in that: the body shape of movable contact spring is Back Word type, upper in Back Word type, lower two ends extend to form moving contact end and electric connecting terminal respectively, center line upper punch along movable contact spring between nearly moving contact end on the front of movable contact spring is pressed with a reinforcement, reinforcement half is in movable contact spring main body, reinforcement second half on moving contact end, the corresponding reinforcement position, the back side of movable contact spring forms groove, length and the width of the length of groove and width and reinforcement are consistent.。The utility model has the advantages that the hardness adding movable contact spring before not affecting its material flexibility and be flexible under topic, solve domestic phosphorus brass material partially soft (as used ultrahard material, its pliability difference and shaping easy to crack) and the problem of fatigue resistance difference, through repetition test, the electrical endurance of product effectively can be improved.
Accompanying drawing explanation
Accompanying drawing is structural perspective of the present utility model, and Fig. 2 is the structural representation (schematic diagram that movable contact spring is folded flat) of movable contact spring of the present utility model, and Fig. 3 is the partial side schematic view of Fig. 2.
Embodiment
A kind of improved electric magnetic relay in figure, comprise pedestal 1, iron core 2, coil 3, yoke 4, armature 5, movable contact spring 6 and static contact spring piece 7, it is characterized in that: the body shape of movable contact spring is Back Word type, upper in Back Word type, lower two ends extend to form moving contact end 8 and electric connecting terminal 9 respectively, center line upper punch along movable contact spring between nearly moving contact end on the front of movable contact spring is pressed with a reinforcement 10, reinforcement half is in movable contact spring main body, reinforcement second half on moving contact end, the corresponding reinforcement position, the back side of movable contact spring forms groove 11, length and the width of the length of groove and width and reinforcement are consistent.
The body shape of movable contact spring is hollow by the utility model, the upper/lower terminal of hollow extends to form moving contact end and electric connecting terminal respectively, be installed with along the center line upper punch of movable contact spring between the corresponding main body of a side surface of movable contact spring and moving contact end and put a reinforcement, reinforcement half is in main body, second half is on moving contact end, by increasing the method for a reinforcement on movable contact spring, the corresponding reinforcement position, opposite side surface of movable contact spring forms groove, and length and the width of the length of groove and width and reinforcement are consistent.The hardness of movable contact spring is added under topic before not affecting its material flexibility and be flexible, solve domestic phosphorus brass material partially soft (as used ultrahard material, its pliability difference and shaping easy to crack) and the problem of fatigue resistance difference, through repetition test, effectively can improve the electrical endurance of product.
Claims (1)
