Abstract: A method for making and testing the thermal compression bond between a wire and a contact or terminal lead of a connector wherein the wire and contact/terminal lead are positioned between opposing electrodes, and a direct current is passed through the electrodes, wire and contact/terminal lead to make a direct attach thermocompression bond. Sample bonds are subjected to a peel test to determine if the thermocompression bonds are within specification. The peel test includes securing the contact/terminal lead, bend the wire 90 degrees from the contact/terminal lead, and applying force to the wire at a constant rate of pull until thermocompression bond is broken and the wire is separated from the contact/terminal lead. The peel force required to break the bond is then compared to a standard to determine if the thermocompression bonds are within determined specifications. Additionally, an axial pull test may also be performed.

Abstract: The present invention is directed to an electrical power connector including a U-shaped body including a first wall with a first plurality of undercut grooves and a second wall that has a second plurality of undercut grooves and a base member that has a third plurality of rectangular slots. A first plurality of spring contacts are each positioned in a corresponding one of the first plurality of grooves. A second plurality of spring contacts are each positioned in a corresponding one of the second plurality of grooves. A third plurality of carrier mounted pins are each positioned in a corresponding one of the plurality of rectangular slots.

Abstract: A trenching apparatus is provided having a base support which mounts a boom structure carrying a digger arm operative to form a trench alongside the base support along a trenching line. The base support includes a pair of longitudinally spaced sleeve members connected to a first track assembly which slidably receive a pair of longitudinally spaced slider members connected to a second, wider track assembly. An adjustment mechanism is provided to move the slider members, and, in turn, the second track assembly, laterally within the sleeve members between a retracted, transport position in which the first and second track assemblies are spaced relatively close to one another and readily fit upon a trailer commonly used to transport heavy equipment along roads and highways, and an extended, operating position in which the first and second track assemblies are relatively widely spaced from one another to provide the apparatus with acceptable stability during a trenching operation.
