Patent

CA 2241851

The invention relates to a method for manufacturing a housing part with screening functions and a housing part with screening functions for a radiocommunication equipment having saucer-type housing parts with overlying, facing open sides to lodge the radiocommunications device. To shorten the manufacturing process by one step, a wire web which has been cut according to the inner contours of the housing part is introduced in an injection mould for the screening housing part. In said wire web, all contact surfaces and their counterparts are coated with a foil corresponding to the dimensions of the desired contact surface. The foils are removed after subsequent injection moulding with insulating material.

L'invention concerne un procédé de production d'une partie boîtier dotée d'une fonction de blindage et une partie boîtier avec fonction de blindage pour un matériel de radiocommunication comprenant des parties boîtier en forme de coques assemblées par leurs côtés ouverts et destinées à loger le dispositif de radiocommunication. Pour supprimer une étape de production, on introduit dans un moule pour moulage par injection destiné à la partie boîtier à blinder un tissu métallique découpé d'après les contours intérieurs de la partie boîtier à effet de blindage. Toutes les plages de contact de ce tissu métallique sont, avec leurs contre-éléments de contact, revêtues d'un film ayant les dimensions des plages de contact souhaitées et, au terme du procédé de moulage par injection réalisé avec un matériau isolant, les films sont retirés.
