Among them, cable-to-cable connectors are developing particularly rapidly, and the general development direction is towards small product size, large transmission current, easy installation, and stronger versatility. The general wire-to-board connection system requires two interoperable connectors. The terminal of the connector at one end is connected to the PCB, and the cable is connected to the terminal at the other end by riveting or ultrasonic welding. The plastic body is used as the carrier of the terminals at both ends to form male and female connectors. In this way, when the connectors at both ends are interoperable, current transmission can be achieved.
