Abstract: A high-current connector for an electric vehicle includes a housing, a screen housing and a high-current contact device. The housing surrounds a housing interior, in which the screen housing is arranged. The screen housing delimits a screen housing interior, in which the high-current contact device is arranged. The screen housing has a deep-drawn first screen housing shell and a first catch spring extending away from the screen housing interior and connected to the first screen housing shell without gaps. The housing has a projection at a side facing the housing interior. The first catch spring extends along a first axis and the projection is orientated inclined relative to the first axis. The first catch spring blocks, with a first catch face orientated inclined relative to the first axis, a movement of the screen housing along the first axis by the first catch face striking the projection.

Abstract: A contact pin for a plug connector includes a contact wire and an impedance adaptation element from a residual piece of a bandoleer strip, wherein the impedance adaptation element is arranged between the two ends of the contact wire. A plug connector includes the contact pin and a shielding receiving the contact pin as an inner conductor, wherein the shielding has a cross-sectional jump between the two ends of the contact pin along a longitudinal direction of the shielding, wherein the impedance adaptation element of the contact pin is arranged in a longitudinal direction of the contact wire at a level of the cross-sectional jump of the shielding. Manufacturing methods are provided for such a contact pint and plug connector.
