PROBLEM TO BE SOLVED: To provide a connector which can suppress leakage of a residual liquid in a connection adapter when a communication state with a mixed injection member is made an off state, after using the connection adapter.SOLUTION: A connector 1 comprises a connection adapter 10, a connection cover 5, and a mixed injection member 20. The connection adapter 10 provides a pair of engagement parts 12K in two directions of the side part of an intermediate part 12, forms an R part 11R having a first curvature on an endmost end DE side of a terminal part 11. The connection cover 5 forms a pair of upper paths 5PU in two directions of the side part S over an upper side to a lower side of an inner wall of an upper part 5U, forms a step part 5UD on the lower part D side of the inner wall, and forms a pair of engagement parts 5UM in two directions of the side part S. The mixed injection member 20 has a port 21, a plug body 30, and a cap 21C. The plug body 30 has a projection part 31 on the upper part U side on an almost center part, the projection part 31 forms a narrow hole 35 from the upper part U to the lower part D side of the almost center part, and the upper part U side of the projection part 31 forms an almost R-state groove part 32 having a second curvature, or the upper part U is made flat.SELECTED DRAWING: Figure 5 |
