Quick connector coupling

摘要

Quick connector coupling having a connector body to receive a male member with a radial upset comprised of two separate, interconnected components, a head element and a sealing element which define a through-hole from a male member entry port at the end of the head element axially to an exit port at the end of the sealing element. A retainer for releasably securing the male member to the connector body is ring-shaped, and encircles the connector body head element. It includes at least one retainer element, which reaches through a window in the head element and interacts with the radial upset of the male member to secure the male member in the connector body.

主权项

1. Quick connector coupling for establishing a separable connection in a fluid line comprising:
a connector body defining a throughbore generally cylindrical about a central axis, to receive a tubular male member, said body comprising a head element having a wall defining a male member entry port at one end thereof and at least one window extending through said wall and communicating with said throughbore, spaced from said male member entry port, and a sealing element defining an exit port at one end thereof, wherein a portion of said head element is partly inserted into said sealing element, and secured thereto, a male member in said male member entry port having a radial outward upset spaced from an end thereof, a retainer cooperating with said upset releasably securing the male member to said connector body, said retainer having a ring fully encircling the connector body radially outward of said wall thereof, whereby the retainer includes at least one locking lug connected to said retainer ring at an end thereof, which locking lug extends through said at least one window in said wall of said connector body and includes a free end within said throughbore that interacts with said upset on said male member to releasably secure the male member to the connector body when said male member is fully inserted into said connector body.
