ABSTRACT:
A hand tool of the pliers-type configuration used for crimping electrical terminals is disclosed. The tool includes a pair of jaws movably with respect to one another by the actuation of a pair of handles. The jaws define a crimping nest which supports an electrical terminal. One die of the crimping nest includes a raised surface, and depending tapering side walls. The raised surface of the die has an hour-glass configuration. The particular shape of the die limits the pressure applied to the terminal during crimping, so as to reduce the tendency to overcrimp the terminal.
