Connector material The material of connector insulation is generally PA66, PBT, ABS, PC, etc. Contact material is generally selected from brass, phosphor bronze, beryllium copper, copper nickel silicon and so on.
Connector housing materials are generally divided into two materials: plastic and metal.
There are several reference points about how to choose plastic or metal materials:
1. Due to the demand for lightweight vehicles, automotive connector manufacturers, especially passenger car manufacturers, will try to choose plastic connectors to control the weight of the vehicle under the premise of meeting product performance.
2. The use environment of the product is better than that of plastic due to its mechanical strength. Therefore, in some harsh environments, metal connectors are more suitable. For example, special vehicles, muck trucks, and unconnected electrical connections when the vehicle is being deployed. At this time, the mil spec electrical connectors made of metal is slightly better than the connector made of plastic in terms of environmental impact and mechanical strength.
3. Shield implementation For the shield connector, since the shell of the metal connector itself is used to conduct the shield, a shield protection carrier is formed. In general, metal connectors are easier to achieve better shielding effectiveness than plastic connectors, and their appearance is more compact.
