A method for producing a crimp connection includes a mobile supply unit that can be connected with a crimping press station for storing and supplying crimp contacts to the crimping press station. The mobile supply unit is loaded with two supply rolls with crimp contacts that can be attached laterally to the mobile supply unit. Each supply roll is assigned to a respective coupling device by which the supply unit can be connected in two docking locations with the crimping press station and disconnected from the docking locations.

Methods of connecting wires (126) to feedthrough pins (104) and apparatus including wires connected to feedthrough pins.

A contacting device (100) for connecting an electrical conductor (11) comprises a connection contact (101) for fixing the electrical conductor (11) to the contacting device (100), wherein the connection contact (101) has a retainer (110). The retainer (110) has an accommodating region (112) for accommodating the electrical conductor (11). The accommodating region (112) tapers between an inlet opening (E112) and a base surface (B112) of the accommodating region (112) in such a way that a cross section (A11) of the electrical conductor (11) is deformed when the electrical conductor (11) is inserted into the accommodating region (112), whereby the electrical conductor is retained on the connection contact (101) in the clamping seat. The electrical conductor (11) can thus be fixed to the connection contact (101) without bending of the retainer (110).
