Abstract
The utility model relates to an electromagnetic relay, comprising an iron core, a coil, a yoke iron, an armature, a movable reed and a static reed; the main body shape of the movable reed is a loop; a movable contact end and an electric connecting end are respectively extended from upper and lower ends of the loop; a reinforced rib is arranged between one side surface of the movable reed, corresponding to the main body and the movable contact end along a central line of the movable reed; a half of the reinforced rib is arranged on the main body; and another half is arranged on the movable contact end. In the utility model, a reinforced rib is added on the movable reed, thus increasing the hardness of the movable reed in the condition of not influencing the flexibility and the elasticity of the material and solving the problem of soft performance (for instance the superhard material has poor flexibility and easy cracking after moulding) and poor fatigue resistance of the domestic phosphorized copper material; and after repetition test, the electromagnetic relay effectively increases the electric appliance service life.
Description
Technical field
The utility model relates to a kind of electromagnetic relay.
Background technology
Movable contact spring in the electromagnetic relay is original use be the import beryllium-bronze of 0.15mm thickness as the moving plate material, its advantage is a good springiness, fatigue resistance is strong.But material price height, materials procurement be difficulty, and cost performance does not have advantage; Present situation on product of the same trade at present: at above-mentioned defective, it is the movable contact spring material that the relay product of present relay industry generally adopts homemade phosphor-copper, cheap and the easily buying of this material price, used in relay product by wide model, its material behavior can satisfy the specification requirement of most of product, but on the product of some movable contact spring molding structure complexity, its elasticity and fatigue resistance can't satisfy the requirement of product, cause the appliance life of product short partially;
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of better quality, longer electromagnetic relay of life-span are provided.
For achieving the above object, the utility model adopts a kind of electromagnetic relay, comprise iron core, coil, yoke, armature, movable contact spring and static contact spring piece, wherein the body shape of movable contact spring is back type, the upper/lower terminal of the type of returning extends to form moving contact end and electric connecting terminal respectively, center line along movable contact spring between corresponding main body of a side surface of movable contact spring and moving contact end is provided with a reinforcement, reinforcement half on main body, second half is on the moving contact end.
The utility model is by increasing the method for a reinforcement on movable contact spring, do not influence its material pliability and flexible before increased the hardness of movable contact spring under the topic, it is soft partially (as using the ultrahard material to solve homemade phosphor-copper material, its pliability difference and moulding are easy to crack) and the problem of fatigue resistance difference, through repetition test, can effectively improve the appliance life of product.
The corresponding reinforcement position, opposite side surface that the utility model further is set to movable contact spring forms groove, and the length of groove is consistent with the length and the width of reinforcement with width.
