Abstract
The utility model discloses a connection plug which is connected with a socket having an arc spiral groove. The connection plug comprises a housing (1), a pin insulator (2) and pins (7). The connection plug has a reverse snap connection mode. The connection plug further comprises a connection nut assembly (3), a sealing ring (4), a friction gasket (5), a ripple spring (6), a sealing ring (8), a line sealing body (9), a ling sealing sleeve (10) and a tail nut (11). The pins (7) are specifically 16# pins, and fixed on the pin insulator (2) by holes in the pin insulator (2). The connection plug is provided with an error proof key for preventing the problems that the use requirements cannot be met or safety hidden troubles are generated because of mis-operation in plugging. The connection plug is small in size, satisfying the requirements on the connector size and operation place in a narrow space, and has relatively high economic and social values.
