High-withstanding voltage subminiature electromagnetic relay

Abstract

The present invention discloses a high-withstanding voltage subminiature electromagnetic relay. The subminiature electromagnetic relay comprises a moving reed part and a fixed reed part, the moving reed part comprises two moving reeds, and a connecting body which spans an acting magnetizer and can communicate two normally open contacts and / or two normally-closed contacts is also connected betweenthe two moving reeds. First positioning and welding parts used for positioning an overall acting assembly are also arranged at the outer sides of the two moving reeds, the second positioning parts matching the first positioning and welding parts are integrated in a pedestal part correspondingly, at the same time, a common terminal at the second positioning parts is canceled. The subminiature electromagnetic relay of the present invention can achieve the purpose of simplifying the relay leading-out terminal design and the user PCB design under the premise of not influencing the original performances of the relay, at the same time, and enables the paths through which the currents flow in the circuits to be shortened. Moreover, the paths through which the signals flow in the circuits do not pass the welding positions of the moving reeds and the leading-out terminals, so that the welding requirements are reduced, and the circuit reliability is improved.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a high withstand voltage ultra-small electromagnetic relay. Background technique [0002] The existing ultra-small electromagnetic relay, because the main application field of the product development is network communication at the beginning, its characteristics are: the product size is small, the coil has low power consumption, the movable contact is a double-contact structure to improve reliability, the contact The form is two sets of conversion specifications, the load current of the main application is not large, and the withstand voltage requirement is not high. With the development of science and industry, such ultra-small electromagnetic relays are more and more widely used in other fields, such as small current high voltage detection and other fields. The use in these fields is characterized by higher requirements for withstand voltage between open contacts. While meetin...

AI Technical Summary

Problems solved by technology

[0004] This ultra-small electromagnetic relay structure in the prior art has brought the following problems: ① PCB space is limited, and copper foil leads required for series contacts cannot be added; ② Even if PCB has space to increase copper foil leads, since copper foil itself is an electrical conductor , After adding copper foil leads, the insulation distance between other components in the circuit will be shortened, which will affect the reliable insulation of the PCB and the relay itself; Reducing the loop resistance will easily lead to an increase in the temperature rise of the loop and reduce reliability and stability

Based on the above, it can be seen that adopting this method will increase the difficulty of the user's PCB design and bring potential risks
