A contact element for contacting electrotechnical components includes: a leadframe part made of an electrically conductive material, having a recess in a contact tab. The contact tab is formed to be curved at at least one location such that a curving line, along which a curvature is present, extends between a beginning and an end of the recess and runs transversely through the contact tab in a straight line.

The invention relates to a terminal (1), in particular an installation terminal, for connection of an electrical conductor (2) without stripping, having at least one conductor insertion area (13) for inserting an electrical conductor (2), insulated with an insulating material, into the terminal (1) in a conductor insertion direction, wherein the terminal (1) furthermore has, for each conductor insertion area (13), an actuating part (50), which is rotatable about an axis of rotation, and an insulation-piercing contact (30) having a cutting edge (33) for cutting through the insulating material and establishing electrical contact with the electrical conductor (2), wherein the cutting edge (33) extends about the axis of rotation along an arc, wherein the insulation-piercing contact (30) is connected to the actuating part (50) in such a way that, via a rotation of the actuating part (50) about the axis of rotation, the insulation-piercing contact (30) is movable between a contacting position, in which the cutting edge (33) intersects the conductor insertion area (13) for establishing electrical contact with an inserted electrical conductor (2), and a release position, in which the cutting edge (33) clears the conductor insertion area.

An insulation displacement arms. The insulation displacement arms define a conductor or wire receiving slot. The insulation displacement arms have insulation stripping sections, weakened sections and base sections. The weakened sections have weakened section widths which are less than insulation stripping section widths of the insulation stripping sections and less than base section widths of the base section. The weakened sections are resiliently deformed upon one or more insulated conductors engaging the insulation stripping sections of the insulation displacement arms as the one or more insulated conductors are inserted into the insulation stripping zone of the wire receiving slot, allowing the insulation displacement contact to accommodate the one or more insulated conductors of the same type and gauge chosen from a broad range of gauges.

A wire harness assembly including a first connector, a second connector, and conductors extending between the first connector and the second connector. Contacts are provided on the second connector. The contacts have termination sections which are mounted on the second connector, compliant sections which extend from the termination sections, and substrate engagement sections which extend from the compliant sections. The substrate engagement sections have curved contact sections which are configured to be positioned in mechanical and electrical engagement with circuit pads of a mating printed circuit board. Embossments are provided on the curved contact sections to provide additional strength and stability to the curved contact sections.
