Abstract The invention is directed to a method of manufacturing a contact clip composed of a body and a lug which is clad with a conductive coating, according to which the body and the lug are manufactured separately, the aluminium body of said contact clip being provided with a plane-parallel end portion, whereas the lug is made from an aluminium plate clad with copper so that one of the end portions thereof is left unclad, whereupon said body and said lug are butted against each other with said respective end portions thereof, and are joined together by welding. The body may be provided with a projection situated on one of the plane surfaces of the end portion thereof lengthwise the line of welding, said projection being utilized as extra metal when welding.
A process for manufacturing a contact clip, comprising the steps of: providing an aluminum body part having a planar end surface; providing an initially separate copper-clad aluminum lug part having a copper-free planar end surface adapted to abut the planar end surface of said body part; at least one of said parts having a projection adjacent the planar end surface thereof; positioning said parts with said end surfaces in mutual abutment; and butt welding said parts together at said end surfaces, so that said projection flows to provide filler material for the weld.

Claim 3
Dependent Claim
33 words
A method of manufacturing a contact clip as claimed in claim 1, wherein the width of said planar end portion of said body part is not less than the width of said projection.
Claim 4
Dependent Claim
32 words
A method of manufacturing a contact clip as claimed in claim 1, wherein said projection is on said body part and partly protrudes beyond said planar end portion of said body part.
Claim 5
