Title:
CONNECTOR
Document Type and Number:
WIPO Patent Application WO/2021/090769
Kind Code:
A1
Abstract:
A connector 1 has: a connector body (10) comprising a hollow channel (11); and a retainer (20) for keeping a pipe (30) inserted into the hollow channel (11) from dislodging from the connector body (10). A retainer body (21) lies along the outer circumferential surface of a retainer mounting part (14). A bearing part (22) allows the retainer body (21) to rotate from a semi-locked position to a fully locked position. In the semi-locked position, a detection piece (23) passes through a detection hole (16), projects into the hollow channel (11), and is pushed in the axial direction by a bulge (32) in the pipe (30). A sloped face (23a) of the detection piece (23) is sloped in the axial direction to enable the conversion of pushing force to force in the outward radial direction. A first energy conversion mechanism (27) converts the force converted by the sloped face (23a) to rotational energy in the locking direction. In the fully locked position, a retaining piece (26) projects through a locking hole (18) into the hollow channel (11), and prevents dislodgement of the pipe (30) from the connector body (10).
