Abstract

Abstract A tool and method are disclosed for terminating an electrical conductor to a contact member premounted in an electrical connector or the like, wherein the contact member has a terminal portion with a pair of spaced conductor engaging elements. The conductor is inserted into the contact member to seat the conductor within the terminal portion and make electrical engagement between the conductor and the spaced engaging elements. Simultaneously with the insertion of the conductor, sidewall portions of the contact member between the conductor engaging elements are crimped onto the conductor to mechanically retain the conductor in electrical engagement with the contact member. The novel tool includes a pair of crimping curved surface portions for shearing wall portions of the contact sidewalls between the conductor engaging elements and holding the sheared wall portions onto the conductor, with the surface portions intersecting along a common edge portion.
