How to distinguish the male and female terminals of a connector
The two matching connectors have the difference between male and female sockets, with one side of the plug (protruding connector) being the male head and the other side of the socket (concave connector) being the female head.
The male terminal and the female terminal are distinguished by their appearance, with a pointed head generally being the male terminal and a circular hole on the head being the female terminal.
Terminal punching refers to the process of stamping, riveting, and riveting the terminals. The stripped wires and terminals are riveted together using a wire punching machine, and then inserted into a rubber shell to connect with other components for the purpose of current flow.
