Fluid transfer connector
A liquid transfer connector according to the present disclosure is provided with a plug having a plug body in which a fluid channel is formed, a socket having a socket body in which a fluid channel communicating with the fluid channel is formed when the plug is connected, a plug body housing part provided in the socket body, that receives and houses a distal end of the plug body inserted therein at a time of connection, an O-ring provided in the plug body housing part, that seals an outer periphery of the plug body inserted in the socket body and a cleaning liquid supply hole that supplies a cleaning liquid into the plug body housing part at a position opposite to the distal end of the plug body with respect to the O-ring.
1. A liquid transfer connector comprising:
a plug having a plug body in which a first fluid channel is formed, the plug including a first valve which opens and closes the first fluid channel;
a socket having a socket body in which a second fluid channel communicating with the first fluid channel is formed when the plug is connected, the socket including a second valve which opens and closes the second fluid channel;
a plug body housing part provided in the socket body, that receives and houses a distal end of the plug body inserted therein at a time of connection, the plug body being formed along a central axis;
a sealing member provided in the plug body housing part, that seals an outer periphery of the plug body inserted in the socket body at a connecting position where the first valve abuts against the second valve to push against each other to open the first fluid channel and the second fluid channel; and
a cleaning liquid supply hole that supplies a cleaning liquid into the plug body housing part at a position opposite to the distal end of the plug body with respect to the sealing member, wherein
the distal end of the plug body is provided on one side with respect to the sealing member along the central axis and the cleaning liquid supply hole is provided on the other side with respect to the sealing member along the central axis when the plug body is inserted in the socket body at the connecting position.
2. The fluid transfer connector according to claim 1 , wherein the cleaning liquid supply hole is provided to be inclined with respect to the central axis toward the distal end side of the plug body.
