<p>For sealing and shielding purposes, a laminate is used, including a layer of ionomer plastics bonded to a metal sheet or a metal plate. The bonding is made without any addition of adhesive agents between the plastics layer and the metal surface by pressing, in a heated state, the plastics layer against a well cleaned surface. The metal should be such a kind, that its surface is oxidized when stored in air. A multi-layer laminate is used, where one metal layer provides a good electrical shielding and an outermost metal layer provides 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> |
