The connector contact shrapnel - precision

Dongguan precision electronic technology co. , LTD. , founded in 2008, is located in shatian ferry road, factory building area of 6000 square meters, specializing in the production of various types of precision terminal, shrapnel, contact precision shrapnel, lead frame, precision metal stamping parts. Stamping is mainly used for all kinds of mobile phones, connectors, plugs and so on electrician electric field. Contact shrapnel in the connector have three functions: between components provide a current message path. Generate and maintain contact with shrapnel contact pressure. To form a solid contact first, use copper or copper alloy material can easily achieve a satisfactory effect. The conductivity of the copper alloy, though not very high, copper conductive rate of only 10% to 30%; But, for most of the connector, the conductivity is enough. However, the conductivity of the material in the connector used for high current or energy distribution indeed plays an important role, because, in this kind of connector, caused by the rules of the temperature rise, heat and the voltage drop requirements lower impedance. Two other role will be more complex and involves the interaction between material properties and design parameters. Contact shrapnel includes two basic types: socket shrapnel, usually is elastic, another kind is rigid, it make the socket shrapnel produce elastic deformation, resulting in a solid strength. We must consider the material of various performance, and strive to reach equilibrium. For contact interface can be separated, main purpose is to provide shrapnel elastic contact between the two on the surface of the plug to the relay. Material properties mean modulus and yield limit. These properties seriously affects the elastic migration performance and flexible offset. The yield limit is also very important, because it can decrease the insertion force. However the elastic strength must be with manufacturing and crimp performance. Precision contact: wish you a prosperous business, everything goes well, if you want to learn more dynamic, can scan the qr code, pay attention to the public. , is committed to precision stamping processing factory of the world's most professional electronic components
