Improved relay structure

Abstract

The invention relates to an improved relay structure, comprising a pedestal as well as an input loop, a coil assembly, an output loop, a magnetic pole and an illustration which are arranged on the pedestal; wherein the input loop is electrically connected with the coil assembly, the coil assembly is connected with external electric power by virtue of the input loop, so as to generate a magnetic force absorbing the magnetic pole; the output loop is arranged in the interior of the pedestal and is provided with a first output contact, a second output contact and a middle shrapnel which is arranged between the first output contact and the second output contact, wherein the middle shrapnel is in normal elastic contact with the first output contact; one end of the illustration is arranged at the magnetic pole, the other end is arranged against the middle shrapnel, and the illustration is provided with an illustration auxiliary rib which is interlocked with the middle shrapnel. The invention is an action auxiliary structure designed for electromagnetic type relay, so that the middle shrapnel thereof can be switched when the electromagnetic type relay acts.

Description

technical field [0001] The invention relates to an action auxiliary structure designed for an electromagnetic relay, so that when the electromagnetic relay is in action, the shrapnel can be switched reliably, in particular to an improved relay structure. Background technique [0002] Relay is an electronic control component, which has a control system (also known as input loop) and a controlled system (also known as output loop). Relays are usually used in automatic control circuits, and their characteristics are controlled by the small current or voltage of the input coil. A kind of "automatic switch" of current in the circuit, therefore, in the circuit, the relay is usually used for automatic adjustment, safety protection, conversion circuit and other applications; [0003] In terms of structure and working characteristics, relays are generally composed of input sensing mechanism and output actuator. The contact opening and closing are used as the relay action. For the re...

Problems solved by technology

[0008] Although the existing electromagnetic relay has the control effect applied to circuit switching, it may have the disadvantage of inaccurate switching after long-term use, because when the middle shrapnel is pushed by the insertion piece, it uses its own elasticity to produce a slight deflection and bending, and then makes The contact switching between the first output contact and the second output contact, when the relay has been switched for a long time, the shrapnel may be structurally fatigued, which will cause uncertainty when the middle shrapnel intends to retreat back to the first output contact

[0009] In view of the shortcomings of the existing electromagnetic relay structure, which is prone to inaccurate switching after aging, the inventors have introduced an improved relay structure, which is an action auxiliary structure designed for the electromagnetic relay, so as to facilitate the operation of the electromagnetic relay. , the shrapnel can actually switch
