Definitions

• the invention relates to a ribbon cable connector arrangement for connecting an electrical ribbon cable to a plug connector, with the aid of which the ribbon cable can be connected, for example, to conductor tracks of a printed circuit board.
• Such ribbon cables have a row of electrical conductors embedded side by side in an insulating material.
• the conductors can be round conductors with a circular cross section and / or flat conductors with a rectangular cross section.

• a reinforcing layer preferably in the form of a reinforcing film, is preferably applied to that broad side of the ribbon cable end on which the ribbon cable conductors are not exposed, that is to say no insulating material has been removed. This increases the bending stiffness of the ribbon cable, which is reduced by stripping. A material with a relatively high thickness is therefore used for the reinforcing film
