A cable termination that provides low signal distortion even at high frequencies. Conductive elements of the cable are fused to edges of signal conductors in a cable connector or other component terminating the cable. For terminating a differential pair, the conductive elements of the cable may be terminated to opposing edges of a pair of signal conductors in the cable termination. The conductive elements may be shaped such that the spacing between signal paths passing through the conductive elements of the cable and into the signal conductors of the cable termination is uniform.

A welding structure includes: a first metal member and a second metal member that are superimposed and welded together. The first metal member has a hole. The second metal member includes a nugget portion where a part of the second metal member has been melted by heat of laser light and has re-solidified. A peripheral portion of the hole in the first metal member covers the nugget portion. A part of the nugget portion is exposed through the hole.

An electrical feedthrough (1) is provided for improving the thermal properties and the electromagnetic compatibility (EMC) and also for simplified production of a medical instrument (7), in which electrical feedthrough individual contact pins (4), which are guided through a glass body (2) in a housing (20) of the instrument (7), are electrically connected to one another by a pluggable plug element (5), preferably in the form of a sheet metal part. Here, the plug element (5) firstly provides high thermal and electrical conductivity and secondly provides a shielding area that effectively prevents the input coupling of electromagnetic radiation. Preferably, the plug element (5) is formed in such a way that it independently develops a holding force for securing itself to the contact pins (4).
