Problems solved by technology

[0002] The relay is a widely used electronic component, which is used in household appliances, automobiles, industrial control, power systems, communication devices and other fields. The technical performance indicators of the relay have dielectric withstand voltage requirements, especially between the input end and the output end. The dielectric withstand voltage requirement is high, and the method of increasing the distance between the input end and the output end is usually used to increase the creepage distance between the input end and the output end and improve the dielectric withstand voltage between the input end and the output end, but this will cause The size of the relay increases, and the development of the whole machine using the relay requires the relay to be small in size, high in sensitivity, good in insulation performance, high in reliability and low in cost

Embodiment 1

[0031]As shown in the figure, a small electromagnetic relay includes a magnetic circuit system 1, a contact system 2, a push block 3, a cover 4, and a base 5. The magnetic circuit system 1 includes an electromagnetic system 11 and an armature 12. The electromagnetic system 11 includes an iron Core 111, yoke 112, contact system 2 includes static contact group 21 and dynamic contact group 22, base 5 includes relay magnetic circuit system installation part 51, contact system installation part 52, electromagnetic system 11 and contact system 2 are arranged There is a first partition wall 6, and the first partition wall 6 is provided with a first push block chute 62 for installing the push block 3, and one end of the first partition wall 6 is integrally provided with an isolation bend extending toward the magnetic circuit system installation part 51. The folding part 61, the notch of the first pushing block slide groove 62 is arranged on the other end of the first partition wall 6, ...

Embodiment 2

[0034] The technical features are the same as those of the first embodiment, except that the second rib 42 is not integrally provided on the top wall of the casing 4 .

[0035] In the above embodiment, on the relay assembly line, the parts and components of the relay are assembled with the base 5, such as Figure 13 As shown, under the condition that the primary positioning of the base 5 remains unchanged, the pushing block 3, the dynamic contact group 22, the static contact group 21, the electromagnetic system 11, and the armature 12 are installed in the base 5 in sequence on the same axial direction. , simplifies the assembly on the production line of the relay, it is very convenient to operate, and it is easy to realize the automatic production of the relay, which greatly improves the efficiency of the production of the relay; The technical performance parameters of the assembled electromagnetic relay can be well controlled, so that the pass-through rate of the electromagne...
