Abstract
The utility model discloses the movable contact spring of a kind of low-temperature-rise relay, including flexure strip and the installation sheet of afterbody bending thereof, the front end of flexure strip is provided with contact holes, and flexure strip afterbody is provided with about two spaced through holes, is provided with downwardly open locating slot at installation sheet and flexure strip connecting corner.This utility model is by strengthening the contact area of the bending movable contact spring in relay with air, so that its area of dissipation strengthens to accelerate to distribute heat produced by its work；The heat making relay operationally produce distributes in time, it is ensured that the stability of relay work, extends the service life of relay.
Description
Technical field:
This utility model relates to electrical equipment and electrical engineering apparatus field, particularly relates to the dynamic of a kind of low-temperature-rise relay
Reed.
Background technology:
Along with improving constantly of the development of World Economics, living standards of the people and quality of life, household electrical appliance, communication
The quality and quantity of equipment, automobile etc. improves constantly, and this has just required that the higher electromagnetic relay of better quality, environmental requirement comes
Conversion, the circuit controlled in these products.Electromagnetic relay is mainly made up of input part and output part.This two parts bag
Vinculum circle, yoke, iron core, armature, pedestal, the dynamic and static contact spring piece of outfan.When coil at the two ends of its terminal pin plus certain
Voltage or during electric current, hot-wire coil will produce magnetic flux, magnetic flux is produced by iron core, yoke, armature and certain working gas gap
Raw captivation, drives movable contact spring to connect static contact spring piece and realizes break-make and the conversion of circuit.
It is available for the device of heat radiation owing to electromagnetic relay itself does not have and can generate heat in the course of the work, for a long time
Work repeat circuit, it is possible that causes because of heating is bad, causes relay can not use and cause and scrap.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide the movable contact spring of a kind of low-temperature-rise relay,
The heat making relay operationally produce distributes in time, it is ensured that the stability of relay work, extends relay
Service life.
The technical solution of the utility model is as follows:
The movable contact spring of low-temperature-rise relay, it is characterised in that: include flexure strip and the installation sheet of afterbody bending, flexure strip
Front end be provided with contact holes, flexure strip afterbody is provided with about two spaced through holes, installation sheet and flexure strip connecting corner
Place is provided with downwardly open locating slot.
The movable contact spring of described low-temperature-rise relay, it is characterised in that: between described flexure strip and installation sheet, angle is
90°。
The utility model has the advantages that:
This utility model is by strengthening the contact area of the bending movable contact spring in relay with air, so that its heat radiation
Area strengthens to accelerate to distribute heat produced by its work；The heat making relay operationally produce distributes in time,
Can ensure that the stability that relay works, extend the service life of relay.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
See accompanying drawing:
The movable contact spring of low-temperature-rise relay, including the installation sheet 2 of flexure strip 1 and afterbody bending thereof, the front end of flexure strip 1 sets
There are contact holes 3, flexure strip 1 afterbody to be provided with about two spaced through holes 3, coordinate at electromagnetic relay movable contact spring and pedestal
Time glue spots is fixed in a glue hole 3, improve the stability of product, additionally there is heat sinking function.
It is provided with downwardly open locating slot 4, it is ensured that after installation, position is stable, work at installation sheet 2 and flexure strip 1 connecting corner
As time do not have shaking phenomenon.
Between flexure strip 1 and installation sheet 2, angle is 90 °.
Claims (2)
