• the insulation element 18 lies on the area in which the flat conductor rail 2 and connection conductor 6 are stripped and their cores 2d, 6d are exposed.
• the shield contact element 16 lies in an area in which the shield conductor 2b is exposed and is mechanically and electrically contacted with it. Over the extension of the shield contact conductor 16 into the connection conductor receptacle 14, the shield contact element 16 can also come into contact with a shield conductor 6b of the connection conductor 6.
• Fig. 6b shows the housing 8 in the joined state.
• the upper side 8a of the housing and the lower side 8b of the housing are positively and positively locked together via latching elements 22, so that a pressing force can be exerted on the shield contact element 16 and this is applied with a pressing force on the shielding conductor 2b and / or the shielding conductor 6b.
• the housing 8 is shown in FIG. 7 in a side view into the connection conductor receptacle 14.
• the connection conductor 6 protrudes from the connection conductor receptacle 14 from the plane of the drawing.
• FIG. 8 shows the structure of the joined housing 8 in a view parallel to the longitudinal extension of the connection conductor receptacle 16. It can be seen that the core 2d is directly connected to the core 6d. At a distance from the exposed core 2d, the insulation element 18 can isolate the shield contact element 16 from the core 2d.
