CONNECTOR AND CONTACTING SYSTEM

One aspect of the present invention relates to a connector for receiving at least one planar end region of a printed circuit board, or a planar end region of a cable, and comprising: . - an insertion opening section which is designed such that at least one sub-region of said planar end region can be inserted into an interior of the connector in an insertion direction E; . - at least one first lower contact element which is designed to make electrical contact with at least one associated first electrical conductor on an underside of the planar end region, and . - at least one second lower contact element which is designed to make electrical contact with at least one associated second electrical conductor on the underside of the planar end region, . said first lower contact element being arranged to be spaced apart from the second lower contact element in a longitudinal direction L which is oriented at right angles to insertion direction E, . the first lower contact element being different to the second lower contact element, and . insertion direction E and a vertical direction H, which is oriented perpendicularly to both insertion direction E and longitudinal direction L, defining an intersection plane E-H such that the first lower contact element is incongruent to the second lower contact element within said intersection plane E-H. The invention also relates to a contact system.
