Title:
PIPE CONNECTOR
Document Type and Number:
WIPO Patent Application WO/2019/059013
Kind Code:
A1
Abstract:
The present invention prevents fretting wear inside a pipe connector. A connector body (1) has provided therein a gate member (29) provided with a spring portion (33) which permits insertion of a pipe (P) to a regular depth while a state of contact with the pipe (P) is maintained. If an operation to push a retainer (37) is performed in a state in which the pipe (P) has been inserted into the connector body (1) as far as the regular depth, a locking leg (45) of the retainer (37) locks against a bulge portion (6) of the pipe (P), enters between the pipe (P) and the spring portion (33) and deforms elastically in a direction causing the spring portion (33) to move away from the pipe (33), eliminating the state of contact.
