Abstract

An environment-friendly shockproof electromagnetic relay comprises an outer shell and a base. The outer shell, a coil, yoke irons, an iron core, an armature and a moving reed and a static reed of an output end are arranged at the upper end of the base. The coil, the yoke irons, the iron core, the armature and the moving reed and the static reed of the output end are arranged in the outer shell. The two sides of the base are respectively provided with a fixing board. The middle parts of the two fixing boards are respectively provided with a blocking groove. The yoke irons are blocked and arranged in the middle parts of the fixing boards which are arranged at the two sides of the base. A convex barb structure is respectively arranged at the two sides of the middle parts of the yoke irons. The blocking grooves on the two fixing boards form stationary fit and conjunction with the barb structure. The looseness of the yoke irons and the base, which is caused by movement, transportation, falling and other outside forces, can be avoided effectively and the yoke irons and the base do not have to be fixed through dispensing, consequently the pollution of glue on environment and product is reduced, product performance and production efficiency are improved.

Description

A kind of environmental protection, shockproof electromagnetic relay

Technical field:

The utility model relates to electric equipment and electrical engineering apparatus field, is a kind of environmental protection, shockproof electromagnetic relay specifically.

Background technology:

Continuous development along with World Economics, improving constantly of living standards of the people and quality of life, the quality and quantity of household electrical appliance, communication apparatus, automobile etc. improves constantly, and this changes, controls the circuit in these products with regard to requiring better quality, the higher electromagnetic relay of environmental requirement.Electromagnetic relay mainly partly partly is made up of with output input.This two part mainly comprises the moving and static contact spring piece of coil, yoke, iron core, armature, pedestal, output.When coil adds certain voltage or electric current at the two ends of its terminal pin, hot-wire coil will produce magnetic flux, magnetic flux by iron core, yoke be lost, armature and certain working gas gap produce attraction, drives break-make and conversion that movable contact spring is connected the real circuit of static contact spring piece.When product in auto-process or be subjected to external force (fall, knock, transport point produce), may cause loosening between yoke and the pedestal, thereby cause product stability low, shockproof properties difference even complete failure.So overcome this fatal shortcoming.

Existing technology is: yoke be fixed on adopt on the pedestal be go out on the yoke two row reinforcements, rely on the friction of reinforcement to increase the bond strength of itself and pedestal, this bond strength is difficult to guarantee that product is in falling process, yoke and pedestal are not loosening in the transportation collision process, again in order to prevent product to generate heat in the course of the work, friction diminishes, and yoke can escape from pedestal, is stained with glue at the binding site of yoke and pedestal.The problem that this practical technique will solve is: 1, product in transportation, in the falling process and in the course of action of product own yoke and pedestal can not get loose, shockproof properties improves greatly.2, original yoke of cancellation and pedestal junction point glue reduce the pollution of glue to environment and product itself, and work efficiency is improved in the knot saving working hour.

Summary of the invention:

For solving the problem that prior art exists, the spy provides a kind of environmental protection, shockproof electromagnetic relay, design overhead structure by both sides at yoke, the structure that respectively there are a draw-in groove and overhead structure stationary fit in both sides and fit together on the pedestal, because the stability of this cooperation, can effectively prevent because product self action and transport, fall, other external force yoke and the becoming flexible of pedestal extremely, again need not put glue and fix yoke and pedestal; Thereby properties of product are got a promotion, and production efficiency is improved.

The technical solution adopted in the utility model is:

A kind of environmental protection, shockproof electromagnetic relay, comprise shell, pedestal: the pedestal upper end is equipped with the moving and static contact spring piece of shell, coil, yoke, iron core, armature, output, and the moving and static contact spring piece of described coil, yoke, iron core, armature, output all is installed in the shell; The pedestal both sides are provided with fixed head, and fixed head middle part in both sides all has draw-in groove; Described yoke is installed in the middle of the fixed head of pedestal both sides, and the both sides, middle part of yoke are provided with the overhead structure of projection, and draw-in groove on the fixed head of both sides and overhead structure stationary fit also fit together.

Advantage of the present utility model is:

The utility model designs overhead structure by the both sides at yoke, the structure that respectively there are a draw-in groove and overhead structure stationary fit in both sides and fit together on the pedestal, because the stability of this cooperation, can effectively prevent because product self action and transport, fall, other external force yoke and the becoming flexible of pedestal extremely, again need not put glue and fix yoke and pedestal; Thereby reduce the pollution of glue to environment and product self, properties of product are got a promotion, production efficiency is improved.

Embodiment:

A kind of environmental protection, shockproof electromagnetic relay, comprise shell 1, pedestal 2: pedestal 2 upper ends are equipped with the moving and static contact spring piece 7,8 of shell 1, coil 3, yoke 4, iron core 5, armature 6, output, and the moving and static contact spring piece 7,8 of described coil 3, yoke 4, iron core 5, armature 6, output all is installed in the shell 1; Pedestal 2 both sides are provided with fixed head 9, and fixed head 9 middle parts in both sides all have draw-in groove 10; Described yoke 4 is installed in the middle of the fixed head 9 of pedestal 2 both sides, and the both sides, middle part of yoke 4 are provided with the overhead structure 11 of projection, and draw-in groove 10 on the both sides fixed head 9 and overhead structure 11 stationary fits on the yoke 4 also fit together.

Claims

1. an environmental protection, shockproof electromagnetic relay, comprise shell, pedestal, it is characterized in that: the pedestal upper end is equipped with the moving and static contact spring piece of shell, coil, yoke, iron core, armature, output, and the moving and static contact spring piece of described coil, yoke, iron core, armature, output all is installed in the shell; The pedestal both sides are provided with fixed head, and fixed head middle part in both sides all has draw-in groove; The both sides, middle part of described yoke are provided with the overhead structure of projection, and draw-in groove on the fixed head of both sides and overhead structure stationary fit also fit together.
