The connector housing includes an insertion portion having an insertion hole in which the coated electric wire is inserted, a housing portion that surrounds a periphery of the terminal portion of the coated electric wire inserted in the insertion hole, and an electric wire covering portion that protrudes to a back surface side of the insertion portion and covers an outer circumference of a coating portion of the coated electric wire. The holder includes a housing holding portion that holds an outer surface of the electric wire covering portion and an electric wire holding portion that holds an outer circumference of at least a part of the coating portion of the coated electric wire protruding from the electric wire covering portion to a back surface side.

In a method for fastening a contact element (5, 6) in an electrical component (1), a contact element (5, 6) is arranged on a contact surface (3, 4) of a base body (2) of the component (1) and a laser beam (18) is directed onto a region (16, 17) of the contact element (5, 6) in such a way that the base body (2) is not located in the beam direction (24) of the laser beam (18). The contact element (5, 6) is partially melted by the laser beam (18), so that the molten material (7, 8) wets the contact surface (3, 4) and produces fastening of the contact element (5, 6) on the contact surface (3, 4).

Connector assemblies that may be used to connect a cable to one or more contact tails of an electrical connector are disclosed. Some connector assemblies may include a wire extending from a cable and attached to an edge of a contact tail of a signal conductor. At least a portion of the wire may be flattened to form a planar surface that is attached to a corresponding planar surface of the edge of the contact tail. Moreover, some connector assemblies may include a wire extending from a cable that is attached to an edge of a contact tail via a metallurgical bond extending along at least a portion of an attachment interface between the wire and the contact tail.
