Printed board type electromagnetic relay with L-shaped base

Abstract

The invention discloses a printed board type electromagnetic relay with an L-shaped base, which comprises a magnetic path part, the L-shaped base, a movable spring armature component and a fixed spring contact component. The L-shaped base is composed of a bottom plate and a side plate which is formed integrally through radial extension of the bottom plate; the magnetic path part is mounted on the bottom plate of the L-shaped base; the fixed spring contact component is arranged on the side plate of the L-shaped base and is located at one side of the magnetic path part; the movable spring armature component is arranged on the bottom plate of the L-shaped base and is located at the other side of the magnetic path part; the magnetic path part, the movable spring armature component and the fixed spring contact component are assembled by regarding the L-shaped base as a reference for installation. As the L-shaped base serves as the unique reference for installation, the structure is simplified, the assembling error is reduced and the assembling precision is improved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic relays, in particular to a printed board type electromagnetic relay with an L-shaped base. Background technique [0002] In the prior art, a printed board type electromagnetic relay usually consists of a magnetic circuit system, a contact system and an auxiliary system. The publication number is an electromagnetic relay disclosed in US6781490B2, which is composed of a magnetic circuit part, a side plate part and a moving spring part. The magnetic circuit part includes a coil assembly, a yoke iron, an iron core, and a magnetic steel, and the side plate part includes a terminal plate and a static spring. The contact assembly, the limit block, and the moving spring part include the moving spring contact assembly and the armature. The side plate part is inserted into the magnetic circuit part laterally, and the moving spring part is assembled with the magnetic circuit part laterally and rivet...

AI Technical Summary

Problems solved by technology

[0003] In the printed board type electromagnetic relay, the installation reference part of the magnetic circuit part is a coil frame, and the installation reference part of the side plate part is a terminal board, so that there are two installation reference parts in one product, the side plate part and the magnetic circuit part After plugging, due to inconsistent benchmarks and large assembly errors, the assembly accuracy of the printed board type electromagnetic relay is insufficient, which affects the product performance of the relay

[0004] Moreover, the magnetic circuit part of the printed board type electromagnetic relay is provided with a movement limiting mechanism in the X-axis direction, the Y-axis direction and the Z-axis direction, so that it is easy to move in the described direction, and the assembly accuracy of the printed board type electromagnetic relay is relatively poor, which affects product performance
