Abstract
A device for digital data transmission includes a U-shaped support rail and a plastic strand which can be clamped into the U-shaped support rail. A strip-like metal contact conductor is mounted on a portion of the inner side of the plastic strand located frontally opposite and at a distance from an insertion gap for a collector shoe which is longitudinally movable in the support rail. The contact conductor contacts a contact body of the collector shoe. Compared to the plastic strand, the contact conductor has a significantly smaller thickness. A shielding member is provided between the inner side of the plastic strand and the support rail. The shielding member has shield contact surfaces which interact with a contact piece of the collector shoe. The contact conductor is clamped into a longitudinal channel of the plastic strand which is bent into a circular shape. The plastic strand is locked to the support rail. With the exception of the shield contact surfaces, the shielding member is insulated relative to the inner side of the plastic strand. The shield contact surfaces are supported by outer edge portions of the plastic strand and project freely movably beyond projections at the sides of the support rail.
