POSITIVE-FIT CONNECTION BETWEEN A METALLIC LINK AND AN INJECTION-MOULDED PLASTIC PART, NOTABLY FOR SPECTACLES

摘要

The invention relates to a positive-fit connection between a metallic link (2) and an injection-moulded plastic part (1), notably for spectacles, where one end (4) of the link (2) is inserted into the moulded part (1). To provide advantageous conditions of construction the invention provides for the moulded part (1) to form a plug-in recess (3) for the insertion end (4) of the link (2) and for said end to have an undulating click-in shape. The end of the link can be inserted into the plug-in recess (3) owing to a substantially elastic deformation of the walls (6) of the plug-in recess which are configured in accordance with the click-in shape (5) of the end (4) of the metallic link.
