The basic performance of electronic connector can be divided into three major categories: mechanical performance, electrical performance and environmental performance. 1. Mechanical properties In terms of connection function, plugging and unplugging force is an important mechanical property. Plug-in force is divided into insertion force and extraction force, and the requirements for the two are different. … Read more

During the operation of the waterproof type-c female connector, do not extend your hand to the interface to avoid being scratched by the pin. And after the USB warterproof type-c female connector is powered on, do not touch the interface of the connector with your hands to avoid some electric shock accidents. When the waterproof … Read more
