Pluggable self locking connector

A pluggable self locking connector comprising:

• a socket including a socket case, the socket case including a plastic socket core having a plurality of socket pins in the interior and a depression on the inner wall thereof;
• and
• a plug including a plug shell and a snap fit portion slidably coupled to the plug shell, the plug coupled to the socket case and connected thereto, the snap fit portion having a plastic plug core formed with a plurality of plug pins corresponding to the socket pins, the outer wall of the snap fit portion being formed with at least one deformable resilient rib and a bump, the plug shell being formed with an opening for slidably receiving the resilient rib and a resilient latch corresponding to the bump, and the front end of the plug shell having at least one resilient positioning member;
• wherein when the socket and the plug mate, the resilient rib of the snap fit portion and the depression of the socket case mate, when the socket and the plug separate, the resilient rib is confined by the depression of the socket case and the resilient latch of the plug shell and the bump of the snap fit portion are tightly engaged, the front end of the snap fit portion presses the resilient positioning member of the plug shell and a portion of the resilient positioning member is exposed outside the plug shell.
