Abstract
A method for producing a media-tight material composite, in particular comprising a metal solid body and an optionally electrically insulating plastic at least partially surrounding the solid body, preferably as a component of a preferably shielded electrical interface, wherein surfaces of the solid body that the plastic contacts are subjected to a surface pretreatment in order to promote the adhesion of the plastic to the solid body. The disclosure further relates to a cylindrical metal sleeve, in particular as part of a plug connector, and a plug connector or sensory comprising a metal sleeve, produced by the foregoing method.
Claims12
A method for producing a media-tight material composite, comprising a metallic sleeve having outer and inner sides and a plastic at least partially surrounding the metallic sleeve, the method comprising:
- pretreating surfaces of the metallic sleeve contacted by the plastic by a pretreatment to promote an adhesion of the plastic to the metallic sleeve, wherein the pretreatment is a mechanical and/or chemical and/or physical pretreatment, wherein the metallic sleeve is part of a pre-mounted interface, wherein the metallic sleeve is completely surrounded with a metal surface which has photocatalytic properties, and wherein the metal surface is treated photocatalytically over the entire region of the metallic sleeve at the outer and inner sides,
- activating the metallic sleeve of the pre-mounted interface by way of UV radiation, and
- surrounding the metallic sleeve by the plastic.
