Abstract
An elongated bus bar is coated with solder and has a first plurality of large holes, and a second plurality of smaller holes formed therein. The holes are spaced apart predetermined distances which correspond to the distances between terminal posts upon which the bus bar is to be mounted. The larger holes are sufficiently large to remain completely free of the bus bar and also of the solder when it is melted. The smaller holes lie individually in sections of the bus bar which are bent in opposite rotational directions with respect to the main plane of the bus bar, and about the longitudinal axis of the bus bar, to provide an interference force fit between each of the smaller holes and the terminal posts inserted therein. These force fits oppose each other in different terminal post insertions because of the bending of the bus bar around the smaller holes. The bus bar is then heated, as by passing an electrical current therethrough, which flows the solder in and around only those terminal posts which are inserted through the smaller holes to make a good electrical and mechanical connection between the last-mentioned terminal posts and the bus bar.
