Electromagnetic relay

Abstract

The invention relates to an electromagnetic relay which comprises an outer shell, an electromagnetic system, a contact system and a pushing clamp, wherein the pushing clamp is arranged between the electromagnetic system and the contact system, one end of the pushing clamp is connected with the armature iron of the electromagnetic system, the other end of the pushing clamp is connected with a moving reed of the contact system, the upper end of the armature iron is clamped in the pushing clamp, the lower end of the armature iron is movably clamped on a coil frame of the electromagnetic system, the upper part of the moving reed is in an F shape, and the cross edge of the pushing clamp is clamped between the two edges of the F-shaped moving reed. The invention has the advantages that: firstly, the F-shaped moving reed is adopted, the invention avoids the complicated technology that the moving reed needs to be provided with hole flanging, and the like, therefore, the whole electromagnetic relay has simple assembly and high production efficiency, is convenient for automation mass production, and also avoids the defect of unstable contact resistance; secondly, the armature iron structure is improved, a pressure spring piece is canceled, the invention eliminates hidden troubles that the shape of the pressure spring piece is complicated, the pressure of the pressure spring is unstable and is easy to clamp, and the like, and the assembly process of the armature iron is simplified.

Description

technical field [0001] The present invention relates to electromagnetic relays. Background technique [0002] The development of modern electronic technology integration requires the miniaturization of electronic components. Therefore, the miniaturization and low cost of relay products are an important trend in its development. Therefore, it is necessary to carry out reasonable and ingenious design on the structure of existing relays. [0003] Existing relay products generally include a base, an electromagnetic system, a contact system, and a push card between the electromagnetic system and the contact system. In the hole, the hole of the moving reed uses methods such as flanging to solve the problem of the installation of the push card and the action of the mechanism. The processing of this structural part is complicated, the production cost is high, and there are hidden dangers such as unstable contact resistance of the relay. In addition, the armature and the iron core o...

[0003] Existing relay products generally include a base, an electromagnetic system, a contact system, and a push card between the electromagnetic system and the contact system. In the hole, the hole of the moving reed uses methods such as flanging to solve the problem of the installation of the push card and the action of the mechanism. The processing of this structural part is complicated, the production cost is high, and there are hidden dangers such as unstable contact resistance of the relay.

In addition, the armature and the iron core of the electromagnetic system are often connected by a compression spring. The shape of the compression spring parts is complex and the cost is high. The production process of this method is also complicated, and there are hidden dangers such as unstable compression spring pressure and easy jamming
