Abstract:
1. A connector comprising: a housing having a female-side connecting port to which a tube can be connected, a liquid circulation space through which a liquid is passed, and a tubular male-side connecting section communicating with said liquid circulation space; a valve disk made of elastic material and having a hollow section and a top slit formed in the top and received in said housing; a solid pin movably installed in said housing, with at least its top inserted in said hollow section; and an urging section for urging said pin axially, wherein said top slit is closed when said tube is not connected to said female-side connecting port; and when said tube is connected to said female-side connecting port, said tube presses a head of said valve disk to contract said valve disk, causing said top slit to spread, communication is thereby established between a tube interior and said hollow section, and at the same time the head of said pin is pressed to cause said pin to move axially, enlarging a clearance between said hollow section and said pin, thereby establishing communication between said tube interior and an interior of said male-side connecting section successively through said top slit, said hollow section and said liquid circulation space.
