Problems solved by technology

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

[0023] Refer to Figures 1 and 2 for the appearance and internal structure of the embodiment of the present invention, including a magnetic circuit system, a contact system and a base part. Referring to Figure 3-5, multiple sets of moving reeds are connected with plastic parts to form a moving spring row, and the moving spring lead-out pieces are also connected through plastic to form a moving spring lead-out row, and connected by riveting to form the moving contact part of the relay. The movable reed row can be designed as one or more groups of structures. Movable reed is formed into an integral structure by plastic part 3.1, and the hole 3.2,3.3,3.4,3.5 on the movable reed cooperates with the bract 4.1,4.2,4.3,4.4 on the movable spring lead row to cooperate and connect by riveting.

[0024] Moving spring lead-out row also is to connect each lead-out sheet into a whole by plastic part 4.5. To ensure the position accuracy of the bracts 4.1, 4.2, 4.3, 4.4 on the moving spring l...

Abstract

The invention relates to an electromagnetic relay, in particular a low height small-sized high power AC, DC electromagnetic relay with a plurality of contacts, which comprises a magnetic circuit system, a contact system and a chassis portion, wherein at least a group of moving reeds of the contact system are linked into moving reed row through an insulation member, the moving reed lead-out sheets are linked into lead-out row through the insulation member, the moving reed lead-out row and the moving reed row are linked into the moving reed portion of the relay.

Description

technical field [0001] The invention relates to an electromagnetic relay, in particular to a low-height small-sized high-power multi-group contact AC and DC electromagnetic relay. 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 voltage is not high. Generally, the maximum betwee...
