Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a relay which is insulated, voltage-resistant and easy to assemble. Background Art

[0002] The magnetic latching relay is a new type of relay developed in recent years. It is also an automatic switch. Like other electromagnetic relays, it automatically connects and disconnects the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay is completely dependent on the action of permanent magnets, and the conversion of its switch state is completed by triggering a pulse electrical signal of a certain width.

[0003] Relays are widely used in the fields of home appliances and automation control. Customers have relatively high requirements for product consistency and product quality stability. In order to improve the insulation and voltage resistance of the products, especially the insulation and voltage resistance between the contacts and the coil, higher requirements are placed on the product structure. To achieve high insulation performance while meeting the requirements of ultra-miniaturization, the product length is generally increased to increase the creepage distance between the coil and the contacts to achieve improved insulation and voltage resistance. However, this will make the product size larger, which is not conducive to the goal of product miniaturization.

[0004] In order to solve the above technical problems, a relay with high insulation and voltage resistance and easy assembly is proposed. Utility Model Content

The creepage distance isolation length can be increased through the structure of the push piece, the shell and the base, thereby achieving the improvement of the product's insulation and voltage resistance performance without increasing the product size.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] By setting push pieces and baffles, the creepage distance isolation design can be increased to make the creepage distance longer, and the high voltage resistance of the coil and contacts can be achieved without major changes to the internal structure. By adding push pieces between the shell and the base, the creepage distance isolation design can be increased to make the creepage distance longer, and the high voltage resistance of the coil and contacts can be achieved without major changes to the internal structure.
