This leads to occasions where the installation space is small and the input and output isolation are high, such products cannot meet the requirements of use.
[0003] In the existing AC electromagnetic relay, since the armature is generally reset by the tension of the tension spring, the yoke and the armature need to be designed with the hook of the tension spring to fix the tension spring, so a certain space is occupied, resulting in a large product size, which cannot Meet the use requirements of small installation height space

Embodiment Construction
[0020] Such as figure 1 , 2, the present invention includes contact system (static reed part 1, pushing block 2 and moving spring part 3), magnetic circuit system 4, base part 5. see Figure 3-5 , at least one group of moving reeds 3 of the contact system are connected by insulating parts 3.1 to form a moving reed row, and rotating shafts 3.6, 3.7 are arranged at both ends of the insulating parts 3.1. Corresponding shaft holes 2.1, 2.2 are provided on the push block 2, and the shaft holes 2.1, 2.2 form a hinge connection with the shafts 3.6, 3.7, and the clamping holes 2.3, 2.4 on the push block 2 are clamped on the protrusions on both sides of the armature 9. On the platform 9.3, 9.4, when the armature 9 moves, the moving contact part of the drive relay moves through the transmission action of the pushing block 2. When the armature 9 moves, the part of the moving reed is driven to move, and the contacts of the relay are driven to switch. The front ends of the rotating shaf...

Abstract
The invention relates to a low height small-sized high power AC, DC electromagnetic relay with a plurality of contacts and winding shaft pushing mechanism, wherein at least a group of moving reeds of the contact system are linked into moving reed row through an insulation member, the insulation member is provided with a rotation shaft on the two ends, a corresponding shaft hole is arranged on the pushing block, thus forming a hinge connection and pushing the rotation shaft hole on the block to be fastened on the boss of the armature, the movement of the armature drives the moving contact portion of the relay for actuation through the pushing block transmission action. The invention realizes lowered relay height, high electric distance, creepage distance, penetration insulating distance and dielectric pressure resistance.
Description
technical field [0001] The invention relates to an electromagnetic relay, in particular to a small-sized, high-power, multi-group contact AC and DC electromagnetic relay with a twisted shaft driving mechanism at low height. Background technique [0002] As an electromechanical component, relays are widely used in various electromechanical equipment. Conventional small and high-power multi-group AC and DC electromagnetic relays generally include coils, coil leads, iron cores, yokes, armatures, tension springs, moving spring groups, Moving spring part, static spring, contact, arc breaker, base, shell. Among them, the coil is generally installed vertically, the iron core and the yoke are connected by riveting, the armature is riveted with the moving spring group, and stuck on the yoke, and restored by the tension spring. The height direction of the product is large, and the distance between the coil and the contact The isolation is also low, and the dielectric withstand voltag...
