Background
An electromagnetic Relay (Relay), an electronic control device, has a control system (also called input loop) and a controlled system (also called output loop), is usually applied to an automatic control circuit, and actually is an automatic switch for controlling a larger current with a smaller current. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like.
Electromagnetic relay can produce a large amount of heat energy because of the rising of temperature after long-time the use, and current electromagnetic relay reed structural design radiating efficiency is slower, then influences electromagnetic relay's life gently, can lead to electromagnetic relay to burn out because of the high temperature when serious, for this we propose a novel low temperature rise electromagnetic relay.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel low temperature rise electromagnetic relay to solve the current not good problem of electromagnetic relay radiating effect who proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel low temperature rise electromagnetic relay, includes electromagnetic relay organism and shell, the electromagnetic relay organism is installed in the inside of shell, the fixed reed end foot that is equipped with in one side of electromagnetic relay organism bottom, the fixed stationary contact that is equipped with in one side of electromagnetic relay organism top, the fixed reed that is equipped with in top of shell inner wall one side, the one end of reed and the one end fixed connection of reed movable contact, the mounting hole has been seted up to one side on shell top, fixed mounting has the heat conduction piece in the mounting hole, the inner wall of the threaded connection hole that the middle part on heat conduction piece top was seted up and the outer wall threaded connection of radiating block, the fixed a plurality of fin that are equipped with in top of radiating block.
As an optimized technical scheme of the utility model, the end design of reed is two laminated structure.
As an optimized technical scheme of the utility model, the reed end foot designs for three laminated structures.
As an optimized technical scheme of the utility model, the fin is made by the aluminium material.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, only increase the stromatolite on reed head and reed end foot, do not increase the production cost of labor, and strengthen electromagnetic relay's heat-sinking capability again, can effectively avoid electromagnetic relay because the during operation temperature rise is too high and lead to not enough or functional inefficacy of life-span, when electromagnetic relay takes load during operation, the reed of stromatolite thickening can be quick with the heat transfer that reed movable contact and stationary contact produced and scatter, the rethread heat conduction piece is to the radiating block heat transfer, the radiating block dispels the heat through the fin, thereby reduce electromagnetic relay's temperature rise.
