Abstract

In general, a termination device or terminal is provided in one form of the invention which device is lanced from an electrically conductive sheet material. The lead termination device includes a generally flat body having a pair of integral angularly arranged legs, a pair of opposite end sections on one of the legs, a flange extending beyond one of the opposite end sections, a pair of openings through the opposite end sections, respectively, and a slot through the one leg and spaced adjacent the other of the opposite end sections. The one leg is deformed into a generally closed loop, and the opposite end sections on the one leg are arranged in overlaying engagement with each other. The flange on the one opposite end section is inserted into the slot in the one leg spaced adjacent the other opposite end section, and the openings in the opposite end sections are aligned with each other in overlaying engagement.

means integral with one of said opposite side edges of said strip and extending generally perpendicularly therefrom for defining a set of deformable tabs; and

at least one lead means for connection with the winding lead and having a part gripped in electrical contacting engagement by said deformable tabs upon the deformation thereof.

2. A lead termination device formed from a generally thin electrical conductive sheet material and adapted for electrically interconnecting a winding lead of a dynamoelectric machine with a power lead therefor, the lead termination device comprising:

an elongate strip having a pair of generally opposite side edges and being predeterminately bent generally along the length thereof to form a multi-sided closed loop adapted to receive a part of the power lead;
