<p>For sealing and shielding purposes, a laminate (22; 22') is used, comprising a layer (25, 29; 25', 29') of ionomer plastics bonded to a metal sheet (23, 27; 23', 27') or a metal plate. The bonding is made without any addition of adhesive agents between the plastics layer and the metal surface but by pressing, in a heated state, the plastics layer against a well cleaned surface. The metal should be such a kind, that the surface thereof is oxidized when stored in air. A multi-layer laminate is used, where one metal layer provides a good electrical shielding (27; 27') and an outermost metal layer (23; 23') provides a good mechanical strength. The plastics layer at the inner side of a laminate is in the same way bonded directly to margins of electrical connector terminals made of metal.</p> |
