The invention relates to a contact device (15), a
contact system (20), and a method for assembling the
contact system (15), wherein the contact device (15) comprises a
contact element arrangement (65) with at least one
contact element (70), and a housing (60) with a foil housing part (80), wherein the
contact element (70) comprises a connecting section (160), at least one
strain relief section (175, 180) arranged on the connecting section (160), and a
cutting arrangement (170) arranged on the connecting section (160) with at least one first
cutting element (200), wherein the foil housing part (80) comprises a foil housing wall (120), a receiving area (155), a foil receptacle (280), a first
cutting edge receptacle (285), a first web (250), a third housing opening (130), and a bending space (286).wherein the bending space (286) adjoins the foil housing wall (120) on the inside and extends between the first web (250) and the third housing opening (130) along the
insertion axis (115), wherein the foil receptacle (280) adjoins the foil housing wall (120) on the inside and the first web (250) separates the foil receptacle (280) from the first cutting receptacle (285), wherein the foil receptacle (280) and the first cutting receptacle (285) extend along the
insertion axis (115) from the receiving area (155) in the direction of the third housing opening (130) and open into the bending space (286).
