Abstract
Claims
1. A 4-core unidirectional plastic connector socket, comprising a socket housing (1) and a set of terminals (2) disposed within the socket housing (1), characterized in that: The socket housing (1) has an integrally formed core (3), which includes a front core (301) located in the inner cavity of the socket housing (1) and a rear core (302) extending from the rear end of the socket housing (1). A set of independent terminal cavities (4) is provided between the front core (301) and the rear core (302). A terminal positioning groove (5) is provided in the middle of the terminal cavities (4). The terminal positioning groove (5) has a tapered groove (6) at its front end and a retraction step (7) at its rear end. A pin groove (8) is provided at the top of the tapered groove (6). The wiring terminal ( 2) Includes a pin (9) adapted to the pin slot (8), a wire pressing foot (10) integrally formed on the rear end of the pin (9), and a terminal positioning sleeve (11) sleeved between the pin (9) and the wire pressing foot (10). The terminal positioning sleeve (11) has a positioning piece (111) at the front end adapted to the tapered groove (6) and elastic locking feet (112) on both sides adapted to the retraction step (7). A wire (13) is crimped through the wire pressing foot (10). A sealing body (14) is provided at the rear end of the terminal cavity (4) to seal the wire (13).
2.
