QUICK CONNECTOR

摘要

A quick connector, which can securely demonstrate the lock confirmation function by a checker when a piped body is reinserted, is provided. A checker includes reinsertion-inhibiting bosses. Thus, when a piped body is inserted through an opening of a retainer again in such a state as the checker is moved to the lock confirmation position after the piped body has been pulled from out of a housing and the retainer in such a state as the checker is moved to the release position, the reinsertion-inhibiting bosses hock up onto an annular boss, thereby inhibiting the piped body from being inserted into the retainer and housing.

主权项

1. A quick connector to be coupled together with a piped body which is provided with an annular boss on a leading-end side thereof, the quick connector comprising:
a tubular housing; a retainer formed integrally with or coupled together with said housing, the retainer locking to the annular boss of said piped body, which is inserted into the retainer through an opening thereof, thereby inhibiting said piped body from coming off; and a checker not only moved from an initial position to a lock confirmation position by a push-in operation, thereby confirming whether the annular boss of said piped body is put in a state of being locked to said retainer; but also moved from the lock confirmation position to a release position by a further push-in operation, thereby canceling the locking of said retainer to the annular boss; said checker including a reinsertion-inhibiting boss; the reinsertion-inhibiting boss hooked up onto the annular boss when said piped body is inserted through the opening of said retainer again in such a state as said checker is moved to the lock confirmation position, after said piped body has been pulled from out of said housing and said retainer in such a state as the checker is moved to the release position, thereby inhibiting said piped body from being inserted into said retainer and said housing; and the reinsertion-inhibiting boss being free of hooking up onto the annular boss in such a state as said checker is placed at the initial position and at the release position, thereby being free of inhibiting the insertion or pullout of said piped body into or from out of said housing and said retainer.
