Description
Technical Field
The utility model belongs to riveting formula contact subassembly processing field, concretely relates to gas blowing device, riveting equipment with anion generator.
Background
A relay is an electric control device which is widely used, and is an electric appliance which generates a predetermined step change in a controlled amount in an electric output circuit when a change in an input amount (excitation amount) meets a predetermined requirement. It has an interactive relationship between a control system (also called an input loop) and a controlled system (also called an output loop). It is commonly used in automated control circuits, which are actually a "recloser" that uses low current to control high current operation. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like. As a control element, the relay has several functions as follows:
1) the control range is expanded. For example, when the control signal of the multi-contact relay reaches a certain value, the multi-circuit can be switched on, switched off and switched on simultaneously according to different forms of contact groups;
2) and (4) amplifying. For example, a sensitive relay, an intermediate relay, etc. can control a circuit with high power by using a very small control quantity;
3) the signals are combined. For example, when a plurality of control signals are input into the multi-winding relay in a specified form, a predetermined control effect is achieved through comparison and integration;
4) automatic, remote control and monitoring. For example, relays on the automation device, together with other electrical appliances, may form a program control circuit, thereby implementing automated operation.
Because the working pressure of the relay product is small, in order to ensure stable work, the contact resistance between normally open contacts or normally closed contacts needs to be small (usually required to be less than or equal to 50m omega) and the consistency is good, so a processing workshop with high cleanliness is needed, the cost investment is increased invisibly, and the requirement that the contact resistance on the surface of the contact is less than or equal to 50m omega and the consistency is good is difficult to ensure by adopting the conventional processing environment.
