As a professional buyer, do you know that the materials of the contact terminals of the connectors are not the same, what is the difference between them? Maybe my article can help you.

　　Connector: The English name is CONNECTOR. It is also called connector and plug-in unit in China. Generally refers to an electrical connector, that is, a device that connects two active devices to transmit current or signals.


　　Why use connectors?

　　Imagine what would happen if there is no connector? At this time, the circuits must be permanently connected with continuous conductors. For example, if an electronic device is to be connected to a power source, the two ends of the connecting wire must be firmly connected to the electronic device and the power source by some method (such as welding). As a result, it brings a lot of inconvenience to both production and use.

　　What does the connector do?

　　The benefits of the connector:

　　1. Improve the production process

　　The connector simplifies the assembly process of electronic products. Also simplifies the mass production process;

　　2. Easy to repair

　　If an electronic component fails, the failed component can be quickly replaced when the connector is installed;

　　3. Easy to upgrade

　　With the advancement of technology, components can be updated when connectors are installed, and new and more complete components can be used to replace the old ones;

　　4. Improve design flexibility

　　The use of connectors allows engineers to have greater flexibility when designing and integrating new products and when composing systems with components.


　　Comparison of connector contact terminal materials

　　brass

　　Composition: copper and zinc

　　Advantages: cheap, good strength and elasticity, good forming quality

　　Disadvantages: easy to crack due to stress and corrosion

　　Phosphor bronze

　　Composition: copper and tin

　　Advantages: better elasticity than brass, stronger than brass

　　Disadvantages: lower conductivity than brass, and more expensive than brass

　　Beryllium Copper (Be-Cu)

　　Comosition: copper and beryllium

　　Advantages: excellent electrical conductivity, exceptionally good strength and elasticity, good corrosion resistance and wear resistance

　　Disadvantages: expensive, with high hardness, additional wear and stamping and processing equipment
