Novel movable contact spring structure

Abstract

The invention relates to the technical field of movable contact spring structures, in particular to a novel movable contact spring structure which comprises a movable contact spring body, a conductive part is integrally formed at the end of the movable contact spring body in a punching mode, and the conductive part is bent in the vertical direction to form a double-layer structure. A contact pin is integrally punched and formed on the conductive part, and the contact pin is horizontally bent at the conductive part; a single-layer structure is changed into a double-layer material, so that the conductive sectional area of the reed is doubled, the current density is reduced, the heating of a product is reduced, the reed can be formed by directly bending after stamping, the original production process is not changed, the production efficiency is not influenced, the bottom end is smooth after bending, and when the reed is connected with a relay shell, the reed is more convenient to be clamped into a relay; compared with the prior art, burrs are not generated, the mounting efficiency is better, and meanwhile, the reed material is changed into a material (C18150) with very high conductivity, so that the bulk resistance of the movable reed is reduced, the heating of a product is reduced, and the electric service life of the product is prolonged; and meanwhile, the purchase cost of movable spring parts is reduced.

Description

technical field [0001] The invention relates to the technical field of the structure of a moving reed, in particular to the structure of a novel moving reed. Background technique [0002] Relays are generally composed of iron cores, coils, armatures, contacts, reed components, etc. At present, the reed components usually include moving reeds and armatures. The moving reeds not only conduct electricity, but also play a role in the reset support of the armature. At present, most of the moving reeds are formed by stamping and bending. [0003] However, the traditional conductive part of the original moving reed is designed as a single-layer structure, which not only leads to the generation of dander when the moving reed is installed, but more importantly, the conductive part has a small cross-section, high current density, and serious product heating, which greatly reduces the The electrical life of the product. SUMMARY OF THE INVENTION [0004] In view of the problems in t...
