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] At the same time, the electromagnetic relay disclosed by the publication number US6781490B2 has an unstable installation of the static spring contact assembly, which affects the contact performance of the product

Embodiment Construction
[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] refer to Figure 1 to Figure 5a As shown, a small printed board type electromagnetic relay disclosed by the present invention includes a base 1 , a magnetic circuit part 2 , a static spring contact assembly 3 and a moving spring armature assembly 4 .
[0034] The base 1 is L-shaped, consisting of a bottom plate 11 and a side plate 12 integrally formed with the bottom plate 11 in a vertical direction. The L-shaped base 1 makes the structure relatively simple and improves the drawing strength.
[0035] The magnetic circuit part 2, the static spring contact assembly 3 and the moving spring armature assembly 4 are assembled with the L-shaped base 1 as the installation reference, that is, the L-shaped base 1 is the only assembly reference, which simplifies the structure, reduces assembly errors, and improves assembly accuracy.

The invention discloses a small printed board type electromagnetic relay. The small printed board type electromagnetic relay comprises a magnetic circuit part, a base, a dynamic spring armature assembly and a static spring contact assembly; the magnetic circuit part is mounted on the base; a side plate is vertically arranged on the base; at least one vertical axial inserting groove is arranged in the side plate; at least one slot is additionally arranged on the side plate along the thickness direction; the static spring contact assembly is mounted in the axial inserting groove and positioned at one side of the magnetic circuit part; a laterally convex pressing sheet which is inserted into the slot is arranged on the static spring contact assembly; the dynamic spring armature assembly is mounted on the base and positioned at the other side of the magnetic circuit part. With the adoption of the small printed board type electromagnetic relay, a static spring leaf and the base can be contacted firmly; the assembling error can be reduced, and the assembling precision can be raised.
Description
technical field [0001] The present invention relates to the technical field of electromagnetic relays, in particular to a small printed board type electromagnetic relay. 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. Publication No. US6781490B2 discloses a small printed board type electromagnetic relay, 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, an iron core, and a magnetic steel. Plate, static spring contact assembly, limit block, the moving spring part includes moving spring contact assembly and 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 riveted firmly with the yoke iron. [0003] In the printed board type elect...
