Problems solved by technology

[0006] In addition, in the conventional female connector as described above, at the boundary formed between the upper surface of the engaging convex portion of the housing and the lower end surface of the outer peripheral wall of the cap, the dimensional accuracy and assembly accuracy of each component may be poor. wait to form a gap
Moreover, when the locked state in which the locking claw is engaged with the lower surface of the engaging convex portion is released due to an unexpected external force, etc., the locking claw is engaged in the above-mentioned gap, although it is not a normal connection state, but it is difficult to distinguish from the appearance. So it's possible to keep that state and continue using

Embodiment Construction

[0025] Below, refer to Figure 1 to Figure 11 , the embodiments of the female connector of the present disclosure will be illustrated in detail. The same reference numerals are assigned to corresponding elements in the respective figures.

[0026] In each embodiment, regarding the female connector 1, the direction along the second axis O2, which is the central axis of the outer peripheral wall 16 of the cap 11, is referred to as the vertical direction, and the direction from the top of the cap 11 along the second axis O2 is referred to as the vertical direction. The direction of the wall 15 towards the housing 12 ( Figure 5 The downward direction in the middle) is referred to as the downward direction, the opposite direction is referred to as the upper direction, the direction surrounding the second axis O2 is referred to as the circumferential direction, and the direction orthogonal to the second axis O2 is referred to as the radial direction. In addition, in each embodime...

Abstract

The female connector can be connected with a male connector, the male connector is provided with a hollow rod-shaped flow path connecting part and a locking claw, the female connector is provided with a cap, a shell and a valve body, the cap is provided with a top wall with an opening and an outer peripheral wall drooping from the outer peripheral edge of the top wall, and the shell is provided with a valve body. The housing has a cylindrical wall and an engagement protrusion protruding from the outer peripheral surface of the cylindrical wall so as to form a lower surface that engages with the locking claw, and the valve body has a clamped portion clamped by the top wall and the cylindrical wall, and a through portion that passes through the valve body in the vertical direction. A boundary is formed between the upper surface of the engagement projection and the lower end surface of the outer peripheral wall, the outer diameter of the lower end surface of the outer peripheral wall is smaller at the boundary than the outer diameter of the upper surface of the engagement projection, and the outer peripheral surface of the engagement projection has a diameter-expanded portion that expands downward from the boundary.

Description

technical field [0001] The present disclosure relates to female connectors. Background technique [0002] Infusion, blood transfusion, artificial dialysis, and the like are performed using medical tubing or the like to form an infusion line, and through the infusion line, liquids such as medical solution and blood are transported. Medical instruments such as medical tubes and syringes used in infusion lines can be connected to each other using a connector assembly including a male connector and a female connector to which the male connector can be connected (for example, see Patent Document 1). [0003] The male connector includes a hollow rod-shaped flow path connecting portion that defines the first flow path inside, and a locking claw. The female connector has a cap, a housing, and a valve core. The cap has: a top wall provided with an opening into which the flow-path connecting portion provided in the male connector can be inserted; and an outer peripheral wall suspend...
