Abstract:
A hand-operated scissors-type tool for cutting and stripping round and thin flat insulated conductors and cables, comprising:(a) handle means including first and second handle members having first and second ends, and a first pivot pin pivotally connecting together said first ends, said second ends containing thumb and finger openings, respectively, said handle members being pivotally operable between closed and open conditions, respectively, said handle members having lateral side portions that are adjacent each other, respectively; (b) first spring means biasing said handle members toward said closed condition; (c) a pair of flat cable stripping blades; (d) means connecting said flat cable stripping blades with the adjacent lateral side portions of said handle members adjacent said first pivot pin, said flat cable stripping blades having cutting edges that are parallel and spaced when said handle means is in said closed condition; (e) said lateral portion of said first handle member containing: (1) a first cutting recess for receiving an insulated conductor that is to be cut; and (2) a round cable stripping through bore adjacent said cutting recess, said stripping through bore being operable to receive a round insulated layer conductor from which a portion of its insulation is to be axially removed; (f) a cutting and stripping blade having a cutting edge; and (g) variable depth adjustment means adjustably connecting said cutting and stripping blade with said lateral portion of said second handle member, said cutting and stripping blade extending longitudinally of said second handle member, said cutting edge of said cutting and stripping blade being arranged adjacent and extending substantially completely across both said first cutting recess and said stripping through bore, said adjustment means being operable to adjust the position of said cutting edge of said cutting and stripping blade generally transversely relative to said second handle member; (h) the configuration of said first cutting recess being such that when said handle members are in said closed condition, the insulated conductor introduced within said first cutting recess is cut at least partially thereacross; (i) the configuration of said stripping through bore being such that when said handle members are in said closed condition, initial rotation of said tool about the insulated conductor inserted into said stripping through bore causes severing of the insulation layer by said cutting edge of said cutting and stripping blade, and subsequent axial displacement of said tool relative to said introduced insulated conductor effects axial removal of the severed insulation layer from the conductor.
