Abstract

An insulation body has an upper surface with a plurality of electric contact tracks, which lie alongside one another in one plane and run in the plug-in direction. For the purpose of contact area protection, the plug-in end of each of the contact tracks is designed as a curved sliding face or surface for the associated contact spring, and the insulation body is designed at its plug-in end with a step-shaped offset with the transition between the levels in the region of the contact tracks being designed to match the curved sliding face of the contact track and to form a rounded step.

Claims

1. A plug connector having an insulation body which has essentially a rectangular cross-section and on an upper surface of the body has a plurality of electrical contact tracks which lie alongside one another in one plane and extend in a plug-in direction toward a plug-in end of the body, each of said contact tracks cooperating with a corresponding contact spring of a mating connector, which contact springs lie alongside one another to form an electrical contact, the improvements comprising a plug-in end of each of the contact tracks having a curved sliding surface for the corresponding contact spring, the insulation body at the plug-in end having a step-shaped offset with a transition between a lower level at the plug-in end and a second level of the one plane in the region of the contact tracks to match the curved sliding surface of the contact tracks to form a rounded step, and the contact tracks being partially embedded in the plastic of the insulation body with a tip of the curved sliding surface being embedded in said body so that each contact track is fixedly mounted on said upper surface of the insulation body.

2. A plug connector according to claim 1, wherein an outer contact track on each side of the insulating body extends farther in the plug-in direction than the remaining contact tracks so that the curved sliding surfaces of the remaining contact tracks are inwardly offset from the sliding surfaces of the outer contact tracks.
