Abstract
A kind of electromagnetic relay of tool armature thrust auxiliary body, comprise housing, contact system and magnetic circuit system, described magnetic circuit system comprises electromagnetic assembly, yoke and armature, and the outer face of the adhesive part of described armature and the connecting portion of action part is a flare inclined-plane; Described pedestal is provided with a R type hook, and one end of this hook is fixed on pedestal, and its free end is extended with an oblique plate to armature direction, and this oblique plate contacts with the flare inclined-plane low spot of armature is dynamic, and wherein oblique plate is power transmission face near the one side of armature; When the adhesive part of armature is by adhesive, armature rotates counterclockwise around flare inclined-plane low spot, the power transmission face of rake is compressed with the flare inclined-plane of armature and contacts.The utility model utilization hook and the contact point of armature are changed to the thrust that armature provides extra, make electromagnetic relay when action, more easily stablize adhesive between the sound reed of relay, can overcome the impact of deadweight on the suction-combining force of armature simultaneously.
Description
Technical field
The utility model relates to relay technical field, especially a kind of electromagnetic relay of tool armature thrust auxiliary body.
Background technology
Electromagnetic relay, as the automatic switch parts with isolation features, is widely used in the fields such as communication, automobile, Automated condtrol and household electrical appliance, is one of important control assembly.
Electromagnetic relay common in the market comprises the housing be made up of pedestal and shell, is arranged on the contact system in housing and magnetic circuit system, and described contact system comprises and is inserted in movable contact spring on pedestal and static contact spring piece; Described magnetic circuit system comprises electromagnetic assembly, yoke and armature, the upper end of described yoke is connected with electromagnetic assembly, the adhesive part of described armature is between the lower end and pedestal of described electromagnetic assembly, the action part of described armature is positioned at the outside of yoke and upwards extends, the side, top of this action part contacts with a push rod tensioning, and described one end of push rod principle part contacts with the movable contact spring tensioning of described contact system.The electromagnetic relay of said structure due to power less, the suction-combining force between sound reed is less, easily disconnects, and affects the normal work of relay; And can the suction-combining force be affected due to the deadweight of armature, cause the suction-combining force between sound reed unstable, relay performance can be caused equally unstable.
Therefore, prior art needs to be improved and improves.
Summary of the invention
For the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of when the actuating of relay, for armature provides extra thrust, ensures the electromagnetic relay of the tool armature thrust auxiliary body of relay overall performance.
For achieving the above object, the technical scheme that the utility model adopts is:
An electromagnetic relay for tool armature thrust auxiliary body, comprises the housing be made up of pedestal and shell, is arranged on the contact system in housing and magnetic circuit system, and described contact system comprises and is inserted in movable contact spring on pedestal and static contact spring piece; Described magnetic circuit system comprises electromagnetic assembly, yoke and armature, the upper end of described yoke is connected with electromagnetic assembly, the adhesive part of described armature is between the lower end and pedestal of described electromagnetic assembly, the action part of described armature is positioned at the outside of yoke and upwards extends, the side, top of this action part contacts with a push rod tensioning, and described push rod contacts with the movable contact spring tensioning of described contact system away from one end of action part; The outer face of the adhesive part of described armature and the connecting portion of action part is a flare inclined-plane; Described pedestal is provided with a R type hook near connecting portion place, one end of this hook is fixed on pedestal, its free end is extended with an oblique plate to armature direction, and this oblique plate contacts with the flare inclined-plane low spot of armature is dynamic, and wherein oblique plate is power transmission face near the one side of armature; When the adhesive part of armature is by adhesive, armature rotates counterclockwise around flare inclined-plane low spot, the power transmission face of rake is compressed with the flare inclined-plane of armature and contacts.
Compared with prior art, the beneficial effects of the utility model are: owing to adopting above-mentioned structural design, namely utilization hook and the contact point of armature are changed to the thrust that armature provides extra, make electromagnetic relay when action, one, armature thrust is upwards supplied to by hook, more easily stablize adhesive between the sound reed of relay, the impact of deadweight on the suction-combining force of armature can be overcome simultaneously.
Accompanying drawing explanation
