Factory outlets Beck isolation for the switch contact movement

Beck's isolation for the switch contact movement Overview: electrical contact elements there are three: First, riveting pieces: the rivet riveting on copper. Second, welding parts: the sheet is welded to the copper contacts. Third, stamping parts: punch made with composite elements. Contact Performance: To improve the reliability of the contact work, the basic requirements for contact material is: 1, the electrical conductivity and the thermal conductivity of the contact material must be high in order to reduce heat loss through the current contacts, reducing contact Oxidation head surface; (2) contact material melting temperature and a high boiling point, high latent heat of melting and evaporation to reduce arcing or sparking action in the amount of wear contacts and easy to make contact welding occurs; 3, contact materials chemical properties of the surrounding environment to stabilize the contacts by a small contact resistance after environmental changes, the contact resistance stable; 4, the hardness of the elastic contact materials should be appropriate, the hardness is too large, the contact area is small, greater flexibility The material in the contacts are closed, due to the bounce of the contacts between the wear increase; 5, the contact element, contact assembly, contact with copper or copper alloys such as automatic spot welding and automatic riveting integration. Material: silver cadmium oxide, silver oxide, copper, silver nickel, silver tin oxide, silver oxide, indium tin oxide, silver and zinc oxide composite whole. SGS certification, ISO9001 certification 6, the contact material is easy to process and welding; 7, contact materials prices lower. Use of strong electric contact materials, important requirements are: ① having low contact resistance, to prevent overheating by the rated current; ② electrical wear and mechanical wear rate is small, with a longer service life; ③ good anti-welding performance In case of failure can successfully break the circuit; ④ small residual current, breaking the ability strong when breaking a large current interrupter quickly and without causing reignition or continuous current. Use of weak contact material requirements: ① low and stable contact resistance and low electrical wear rate, long life; ② have higher minimum arcing voltage and minimum arc current, the contacts as possible Under no circumstances arc operation; ③ small force of this contact is closed, so mechanical wear is not a significant issue. DC contacts required under current operating conditions, the transfer from one contact to the other side of the material to be small. Electrical contact elements can be widely used in switches, relays, thermostats, circuit breakers, contactors, controllers, timers and other low voltage electrical products and home appliances products. For the production of electrical contact elements, the existing German imports CNC automatic welding machine, riveting machine, spot welding machines, high-speed punch, punch, microscope, projector, 3D imaging device, such as production, testing equipment 150 sets can be developed according to the specific requirements of the user.
