Fluid connector

A fluid connector comprising:

• a shell having a fluid channel;
• a valve member rotatably accommodated in the fluid channel and having a through hole;
• a control element connected to the valve member for controlling the valve member to rotate between a closed position in which the valve member obstructs the fluid channel and an open position in which the valve member opens the fluid channel;
• and
• an interlock system that permits movement of the control element for operating the valve member from the closed position to the open position when a mating connector is connected to the shell;
• wherein the shell has an interface for abutting a mating connector and an accommodating hole concavely formed on the interface to accommodate the interlock system;
• wherein
• the interlock system includes a first pin selectively movable within the accommodating hole between a first position in which the first pin protrudes outwardly from the interface and a second position in which the first pin retracts inwardly compared to the first position, a second pin movable within the accommodating hole, and a first spring supporting the first pin;
• when the fluid connector does not abut the mating connector, the first spring maintains the first pin in the first position, and the interlock system further includes a restricting member preventing the control element from rotating the valve member;
• when the fluid connector abuts the mating connector, the first pin is biased by the mating connector from the first position to the second position, and the control element is free of restriction by the restricting member so that the control element operates the valve member to rotate between the closed position and the open position;
• and
• the fluid connector further includes an operating member operatively connected to the control element and the second pin;
• when the control element opens the valve member, the second pin is pushed to an extending position by the operating member;
• and when the control element closes the valve member, the second pin is moved to a retracting position accommodated in the accommodating hole.
