Connector structure with lock mechanism

A connector structure with a lock mechanism, said connector structure comprising a supply connector for supplying fluid and a reception connector for receiving the supply of fluid,

• and is characterized by possessing an operating member that shifts in conjunction with the connection movement of said supply connector and said reception connector, by providing a fastening mechanism capable of maintaining a lock condition in which has been fastened said supply connector and said reception connector in conjunction with shifting of said operating member and for releasing the lock condition of said supply connector and said reception connector with further shifting of said operating member in conjunction with the next pressing inward operation of said operating member, and by providing a force applicator for applying force in the separation direction to said supply connector, and being capable of supplying fluid from said supply connector to said reception connector,
• wherein said connector structure is further characterized by the fastening mechanism providing a mating component disposed on said supply connector and an operating member disposed on said reception connector and which is capable of shifting in conjunction with the pressing inward operation of said supply connector and mating with said mating component,
• wherein said connector structure is further characterized by said operating member being structured with a second ring capable of rotation shift between a first ring and a third ring, that the first ring and third ring maintain rotation capability and axial direction shift capability at the interior of a ratchet holder, that the second ring provide guide protrusions for mating with ratchet steps disposed on said ratchet holder, and locking protrusions for mating with mating protrusions to act as mating components disposed on said supply connector, and slide hooks for receiving rotation force by contact with the third ring, so that the second ring shifts in the axial direction through influence of the first ring in conjunction with the connection operation of said supply connector, that while in such transit it receives rotation force by contact with the third ring, that it rotation shifts by one increment in conjunction with the change in mating position for the single instance axial direction shift, that said locking protrusions enters a lock condition by mating with said mating protrusions, and that at the next axial direction shift the second ring rotation shifts by the next one increment and mating between said locking protrusions and said mating protrusions is released.
