Novel armature assembly for relay

Abstract

The invention discloses a novel armature assembly for a relay, and relates to the technical field of relays, the novel armature assembly comprises a support, a movable contact spring, an armature block and an elastic telescopic rod, the support is arranged to be in a horizontally-placed L shape, a through groove is formed in the middle of one side face of the support in a penetrating mode, and a fixing shaft fixedly connected with the support is arranged at the upper end of an inner cavity of the through groove; a movable shaft is arranged at the lower end of an inner cavity of the through groove, the movable contact spring is located at the upper end of the support and horizontally placed, one end of the movable contact spring is movably connected to the outer side of the fixed shaft in a sleeving mode and can rotate around the fixed shaft, and the two side faces of the movable contact spring are attached to the upper ends of the inner walls of the two sides of the through groove respectively. The armature block is installed in the middle of the inner wall of one end of the installation groove, the hollow cylinder and the movable contact spring are installed on the same side of the support, and compared with a traditional relay that a reset spring and a movable contact spring are installed on the two sides of the support respectively, the overall size of the device is effectively reduced under the condition that rotation of the movable contact spring is not affected.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a novel armature assembly for relays. Background technique [0002] The relay is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity meets the specified requirements. It has an interactive relationship between the control system and the controlled system. Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. [0003] The armature generally refers to the iron block that is sucked up and down by the electromagnet in the electromagnetic relay, and the working circuit is closed after the movement. It is not necessarily a m...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing armature assembly for relays, when it is energized, the armature drives the moving reed to rotate and squeeze the return spring, but with the shape of the return spring As the variable gradually increases, the elastic force of the return spring will also increase accordingly. When the elastic force of the return spring is greater than the magnetic force between the armature and the iron core, the armature will not be able to drive the moving reed to rotate, thus making it easy to make the moving reed mounted on the moving reed. The moving contact cannot make contact with the static contact, causing the relay to fail to work properly
