Embodiment Construction

[0031] A male connector with a lock mechanism according to the present invention includes a bar-shaped male member inserted into a female connector, and a lock mechanism for maintaining a state in which the male member is inserted into the female connector. The lock mechanism includes: a shroud disposed to surround the male member and into which the female connector is inserted; and a single lock lever of an elastically displaceable cantilever support structure. The lock lever includes a claw that engages with the female connector, and an operation portion for elastically displacing the lock lever in a direction away from the male member. The claw and the operation portion are provided on a free end side of the lock lever.

[0032] Preferably, the above-mentioned male connector with a lock mechanism of the present invention further includes a displacement limiting member that sets an upper limit of the elastic displacement amount of the lock lever. Accordingly, it is possible...

Abstract

The locking mechanism includes: a shield (20) configured to surround the male component (10) and for insertion of the female connector (100); and a single locking lever that is elastically displaceable in a cantilevered structure (30). The locking lever (30) has a pawl (34) engaged with the female connector (100), and an operation part ( 35). The pawl (34) and the operation part (35) are provided on the free end side of the lock lever (30).

Description

technical field [0001] The present invention relates to a male connector provided with a locking mechanism for maintaining the connection state of the male connector and the female connector. Background technique [0002] When infusion or blood transfusion is performed on a patient, or extracorporeal blood circulation is performed during surgery, it is necessary to form a path (transfer line) for transporting a liquid such as a medical solution or blood. The transfer line is generally formed by connecting containers, various instruments, liquid delivery pipes, and the like. In addition, when injecting the medical solution administered to the patient into the medical solution bag (container), it is necessary to connect the medical solution bag and the syringe, and the like. In this way, a male connector and a female connector are used to detachably connect different components to each other. [0003] As an example of a female connector used for this purpose, a needle-less p...
