ABSTRACT:
A head assembly for a compression tool including a pair of opposite, rotatably mounted jaw members. Each jaw member having a compression end which is moveable between a first position in engagement with the compression end of the opposite jaw member and a second position wherein the compression ends are spaced apart from each other. The compression end of each jaw member having an interior nib surface, a semi-circular groove surface, an engagement surface and distal compression surface. The head assembly includes a center nib which is operably associated with the interior nib surface of each jaw member to provide three generally equidistant points of contact around the circumference of a connector that is placed therebetween for compression. The two jaws and the center nib form a first compartment, a second compartment and a third compartment in serial alignment, with each compartment adapted to selectively compress a connector and with said engagement surfaces in direct overlapping engagement with each other in response to movement of the jaws to the first position. Each compartment providing multiple areas for deformation flow within the plane of the jaws.
