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.

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.
