HIGH PRESSURE QUICK CONNECTOR

摘要

The present invention is a high pressure quick connector (20) especially for use in connecting brake lines of a vehicle. The connector includes a housing (22) which selectively receives a tube retainer cap (24). Retaining means (48) such as a garter spring (50) or snap ring allow for a low force insertion of the cap (24) into the housing (22) with a very high pull-off force. The cap (24) is used to trap a tube (26) with a bead (30) upset, and the tube (26) may be removed after the cap (24) is unlocked. A second way of releasing the tube includes the use of a tube retainer plug (360) selectively received in the cap (354), the upset (30) trapped between the plug (360) and cap (354). The plug (360) can be removed while the cap (354) is still locked in the housing (352), releasing the tube (26). A release tool may be used to unlock the cap (354) from the housing (352). An insertion indicator ring (400) is used to establish the locking of the cap (354) within the housing (352). A dust boot (94) prevents contaminants from interfering with the operation of the connector.
