Problems solved by technology
However, the existing typical small-scale high-power electromagnetic relay generally adopts a structure in which a circular iron core is riveted with a yoke and then a moving spring is assembled on the yoke. This structure has a large installation area, and the withstand voltage between the input and output is generally only 2500VAC, or the The magnetic circuit system and the contact system are divided into two parts, separated by a partition wall in the middle, and the withstand voltage has been improved to a certain extent, generally up to about 4000VAC. They all have insufficient compact structure and insufficient space utilization, resulting in insufficient product volume and isolation. low degree and other disadvantages

The relay comprises the electromagnetism system, the contact system, the frame, the drive block and the shell case. There is the platform at the one end of the driven block. At the lower part of the platform, there are the flute and the convex rib that grip the relevant convex rib and the flute on the frame. The contact part of the electromagnetism system are installed in the upper and the lower cavities of the frame. The action of the armature drives the movable contact spring to switch the contact point. The structure of the relay prolongs the air distance and the creepage distance between the armature and the movable contact spring so as to enhance the insulation. The products provide the features of compact, easy to assemble and accurate positioning.
Description
technical field [0001] The invention relates to a component of an electromagnetic relay, in particular to a push card and a frame of a carrier part, where corresponding grooves and ribs are respectively provided and engaged with each other, so as to extend the air distance and creep between the armature and the moving reed. Electric distance, electromagnetic relay with improved insulation. Background technique [0002] As an electromechanical component, electromagnetic relay is widely used in various household appliances, instruments, meters and automatic control devices. At present, one of the development directions of electronic technology is high-density assembly technology, which reduces the volume of the whole machine, reduces production costs, and improves market competitiveness. In order to meet the requirements of the whole machine, the relay is also developing in the direction of miniaturization, high isolation, low power consumption, anti-surge, and high power. H...
