Two shot tube retention clip with resilient living hinge

摘要

A retention clip includes first and second body portions created of a first polymeric material. The body portions when angularly rotated apart define an open position, and when rotated into direct contact defining an engaged position. An isolation portion is created of a resilient second polymeric material. The isolation portion includes isolation members connected to the body portions. The isolation members are positioned facing each other when the retention clip is in the engaged position. The isolation members frictionally contact and retain a tubular shaped member in the engaged position. A living hinge integrally connects the body portions allowing the body portions to rotate with respect to each other. The living hinge provides the only connection between the body portions as the body portions transition between the open position and the engaged position. A frangible connector initially integrally connects the first and second body portions only in the open position.

主权项

1. A retention clip, comprising:
first and second body portions both created of a substantially stiff first polymeric material, the body portions when rotated away from contacting each other defining an open position, and when rotated into contact with each other defining an engaged position;
an isolation portion created of a resilient second polymeric material, the isolation portion including:a first isolation portion on the first body portion having a plurality of ribs and a second isolation portion on the second body portion having a plurality of ribs, the ribs of the first isolation portion directed toward the ribs of the second isolation portion such that the ribs compress when receiving a tubular member when the retention clip is in the engaged position; anda living hinge integrally connecting the first and second isolation portions, and thereby connecting the body portions about which the body portions rotate with respect to each other; anda frangible connector of the first polymeric material initially integrally connecting the first and second body portions in the open position, the frangible connector breaking when the body portions move away from the open position and toward the engaged position, and after the frangible connector breaking, the living hinge and thereby the resilient second polymeric material providing the only continuous connection between the body portions as the body portions transition between the open position and the engaged position;wherein the living hinge defines a fixed arc of rotation about which the body portions rotate with respect to each other that remains substantially the same both before and after the frangible connector breaking.
