发明名称 Twist lock connector with reinforcing wing grips and reverse snap assembly
摘要 A connector assembly may be formed by the combination of a latch member and a connector member. The latch member has an annular collar and an arcuate latch wall extending from a circumferential edge of the annular collar. A latch recess and a latch arm are defined within the latch wall. A wing grip extends from an exterior surface of the latch wall adjacent the latch recess and is configured to reinforce the latch arm by countering a tendency of the latch arm to flex radially outward when the connector assembly is subject to a tension load along a longitudinal axis of the connector assembly. A plurality of snap arms are arranged about a circumference of the interior surface of the annular collar to engage the connector member. The connector member receives and retains the latch member directly about an outer male insertion surface thereof rather than passing a barbed end of the connector member through the latch member. The latch member and the connector member are correspondingly configured to freely rotate relative to one another upon assembly. An annular protrusion on an outer wall of the connector member acts as a tube stop.

主权项 1. A connector assembly, comprising: a latch member, comprising: an annular collar with a first open end, a second open end, and a terminal end, the first open end opposing the second open end in a longitudinal direction, and the terminal end extending from the first open end in the longitudinal direction away from the second open end;an arcuate latch wall extending from a circumferential edge of the annular collar and defining a latch recess and a latch arm within the latch wall;a wing grip extending outwardly from an exterior surface of the latch wall adjacent the latch recess to define an angle between the wing grip and the exterior surface of the latch wall and configured to reinforce the latch arm by countering a tendency of the latch arm to flex radially outward when the connector assembly is subject to a tension load along a longitudinal axis of the connector assembly; andat least one snap arm having a free end extending from the first open end toward the second open end; and a connector member configured to receive and retain the latch member about an outer surface thereof, the connector member comprising: an annular protrusion having a first surface, a second surface, and a sidewall, the first surface and the second surface projecting radially outward from the outer surface of the connector member, the sidewall separating the first surface and the second surface, wherein when the latch member is retained on the connector member the annular protrusion is at least partially contained within the annular collar, such that the terminal end of the annular collar is positioned radially about the sidewall of the annular protrusion.
