  • Patent number: 3999272
    Abstract: A tool to facilitate the removal of individual leads underlying others in wiring layers of a backplane terminal pin field. In the past, wiring being removed was frequently pulled against overlying leads causing damage to insulation and even breakage. The tool is provided with sockets to fit over a number of terminal pins for accurate positioning and the lead to be removed is drawn against a guide portion which takes the strain rather than the overlying wiring.
