Mutually fixing two moulded parts - using injection-moulded thin walled sleeve with side detent opening for receiving detent block

摘要

The sleeve (2) forming the socket has a circular or elliptical cross-section and is radially deformable. The detent block on the other part engages in the opening (6) on the sleeve wall (5) by a detent nose (14) which extends across the insert direction. The sleeve is supported radially by guide faces. The detent member can have an insert opening (3) for the sleeve whereby the inner faces running parallel to the insert direction form the support and guide faces. The ID of the semi-cylindrical inner wall area of the insert opening, and the diametric distance between the inner wall area and the opposite flat wall area of the insert opening (3) pref. correspond to the OD (D) of the sleeve. USE/ADVANTAGE - Secure fixing with controlled radial deformation of the sleeve. Low cost mfr.
