Abstract
An assembly includes a tubular body having an axis, an axial end, a bore that is axial an aperture and a retainer groove formed in the bore and contiguous with the aperture. The assembly also includes a retainer mounted in the retainer groove. The retainer has a debris shield located external to the tubular body. The retainer includes a nominal configuration wherein the debris shield is configured to close off access to the aperture and the retainer groove to prevent debris from accumulating therein. In addition, the retainer includes an expanded configuration wherein the debris shield is not configured to completely close off access to the aperture and the retainer groove.
Claims16
An assembly, comprising:
- a tubular body having an axis, a bore that is axial, an aperture through the tubular body, and a retainer groove formed in the bore of the tubular body;
- a retainer mounted in the retainer groove, wherein an entirety of the retainer is configured to be both axially movable and radially movable relative to the retainer groove during formation of a pipe assembly with a pipe in the bore;
- and
- a debris shield located on an exterior of the tubular body, wherein the retainer comprises
- a nominal configuration wherein the debris shield is configured to close off access to the aperture and the retainer groove to prevent debris from accumulating therein, and
- an expanded configuration wherein the debris shield is configured to not completely close off access to the aperture and the retainer groove,
- wherein the debris shield is coupled to a first radial extension of the retainer, extends circumferentially toward, is spaced from, and is disposed radially outward relative to a second radial extension of the retainer, wherein the first and second radial extensions are circumferentially closer to one another with the retainer in the expanded configuration and circumferentially further away from one another in the nominal configuration.
