The connector also belongs to one kind of electronic connector. The other kind of connector is called row pin row bus. The following describes its basic characteristics.

The rated current is met by the thermal design of the connector during the design process of the connector. Because when there is current flowing through the contact, due to the existence of conductor resistance and contact resistance, the contact will heat. When the heat exceeds a certain limit, the insulation of the connector will be damaged, and the softening of the contact to the surface coating will be formed, resulting in the occurrence of the fault. Therefore, to limit the rated current, in fact, is to limit the temperature rise inside the connector to not exceed the specified value of the design.

The rated voltage mainly depends on the insulating material used by the connector and the spacing between contacts. The rated voltage of the connector should be understood as the working voltage specified by the manufacturer.

Contact resistance, contact resistance index of connector refers to contact resistance, which includes contact resistance and contact conductor resistance. Contact conductor resistance is small, so contact resistance is called contact resistance in many technical specifications.
