It is composed of two parts that are plugged and connected. One part compresses the wire and then plugs it into the other part, which is soldered onto the PCB board. This bottom mechanical principle and anti vibration design ensure the long-term airtight connection of the product and the reliability of the finished product. Both ends of the socket can be equipped with matching ears, which can greatly protect the contacts and prevent poor arrangement of the contacts. At the same time, this socket design can ensure that the socket can be correctly inserted into the mother body. The socket can also have assembly buckles and locking buckles. The assembly buckle can provide a more stable fixation to the PCB board, and the locking buckle can lock the mother body and socket after installation is completed. Various socket designs can be paired with different insertion methods for different substrates, such as horizontal, vertical, or tilted towards the printed circuit board, and different methods can be selected according to customer requirements. Both metric and standard wire gauges can be selected, making it a popular terminal type in the current market.
