Problems solved by technology

This technology can only effectively control the formation of contact spatter on the via conductor between the contact mating area and the iron core assembly hole, but it cannot solve or even aggravate the formation of contact spatter in the contact mating area. The formation of the path conductor between the moving contact and the static contact directly affects the stability, durability and safety of the snap-in relay, and it is necessary to make technical improvements to it

Abstract

The invention discloses a coil frame for a clapper-type relay and a clapper-type relay. The coil frame comprises a bobbin, and a first coil baffle and a second coil baffle located at two ends of the bobbin, wherein the top of the second coil baffle is provided with a contact fitting area between a static spring part and a moving spring part; the outer edge of the second coil baffle at the contactfitting area is provided with a concave flow guiding notch; and during the assembly structure with a relay shell, the second coil baffle and the corresponding part on the inner wall of the shell forma flow guiding channel through the flow guiding notch. When the coil frame is applied to the clapper-type relay, accumulation of contact splashes between the moving contact and the static contact in the contact fitting area to form a via conductor can be effectively prevented, and the relay can be ensured to work stably and safely for a long time.

Description

technical field [0001] The invention relates to a relay, in particular to a coil frame for a snap-in relay and a snap-in relay including the coil frame. Background technique [0002] As an electrical control device, the relay plays the role of automatic adjustment, safety protection, conversion circuit, etc. in the circuit, and is widely used in communication, automobile, automatic control, home appliances and other electrical fields. [0003] As a common structural form of relays, snap-in relays have the characteristics of simple structure, compact structure, small size, and low power, and have been widely used in power control of household appliances. [0004] The snap-in relay is mainly composed of a magnetic circuit part, a moving spring part and a static spring part. The magnetic circuit part is mainly composed of the coil frame and the coil assembled on the coil frame, the iron core, the yoke iron and the armature, etc. The armature is docked and assembled on the knif...
