摘要： The present invention relates to a group of hand thermal tools of simplified construction wherein each has the same upper and lower hand grip members hinged together adjacent to their rear ends and moreover the upper and lower grip member may be identical. A power lead line, extending in at the rear of the grip members, powers each tool. The three distinct thermal hand tools contemplated are; resistance tweezers, conductive tweezers, and wire stripper. The resistance tweezers has a single conductor rod in each grip member extending the length thereof and a tweezer blade removably mounted at the forward end of each rod whereby an electrically conductive object tweezed between the blades becomes resistance heated. The conductive tweezers and the thermal wire stripper each utilize a pair of conductive rods in each grip member extending the length thereof and a resistance heated blade member mounted across the forward ends of each rod pair. In the conductive tweezer, a gripping blade is removably mounted across the forward ends of each rod pair, the blades being opposed so that an object tweezed therebetween becomes heated by thermal conductivity. In the wire stripper, a cutting blade is mounted across the forward end of each rod pair, the blades being in opposing cutting relationship whereby an insulated wire may have the insulation stripped therefrom by the cutting action of the heated blades.

摘要： An electrical connector adapted for use on a universal cord for electrically powered hand tools, formed as a female assembly and a male assembly both of a coaxial type of construction. The female assembly comprises a central contact, an outer contact and an insulator member therebetween, the members being nested together so that relative movement in one axial direction is prevented. A centrally apertured second insulator bears against the base ends of the outer contact and other insulator. The rearward end of the central contact extends through the aperture. The second insulator which is retained in position by a lock washer serves to prevent relative movement of the components in the other axial direction. The male assembly also has a central contact, an outer contact and an insulator therebetween. The outer contact and insulator have internal shoulders which nest, and the central contact has a flange thereon which seats against the insulator thereby preventing relative movement in one axial direction. The same lock washer retained second insulator arrangement prevents relative movement in the other direction.
