摘要： An electric connector having a first coupling member (1) and a second coupling member (2) fitted with the first member; the second coupling member (2) comprises an inserting pin (18); the inserting pin has a front end. On the outer peripheral surface of the inserting pin, a plurality of guide grooves are formed and each includes a straight section and a curved section. A metallic contact (24) is arranged at the end of each of the curved sections far away from the straight section; the first coupling member (1) includes an inserting member (4) having a hold (22), a plurality protrusions (5) formed in the hold (22) and extending radially, and metallic contacts (21). Each of the metallic contacts (21) is attached on one section of the peripheral surface of each of said protrusion (5) and faces oppositely to the opening of the hold (22). An insuring means is used to establish the effective electric contact among the metallic contacts (A, B); the protrusions (5) in the first coupling member (1) are used for moving along guide grooves (19) of the second coupling member (2) so as to act as guidance during the connection of the first coupling member (1) with the second coupling member (2), and have the same number as the guide grooves. The metallic contacts (24) of the inserting member (4) are used for electric connection with the metallic contacts (21) of the grooves (19) after the first coupling member (1) and the second coupling member (2) are inserted into and connected with each other.
