Abstract A wire cropping tool which may be used for cropping wires to any required length after insertion of the wires through holes in a printed circuit board, consist of fixed and movable blades relatively movable upon actuation of a piston member reciprocable within a housing, the fixed blade having at the nose, a notch providing a shearing edge extending substantially normal to the plane of the fixed blade and an extension adjacent the shearing edge extending outwardly with respect thereto, and the movable blade being so fulcrummed with respect to the fixed blade as to allow a lug on the extremity of the movable blade and provided with a shearing edge to move through a curved path and substantially normal to the fixed blade thereby providing a positive cropping action. After cropping, the wires may be bent through any required angle and the construction of the tool allows the blades to be inserted into a stack of wires from above, i.e., with the pivotal axis of the blades substantially normal to the axis of the wires, such as to crop the wires thereby avoiding the difficulties of cropping wires by means of a tool inserted laterally or at an angle to the wires as heretofore.
A wire cropping and forming tool including a fixed tapered blade member, a movable tapered blade member pivotally mounted to the fixed blade member for movement relative thereto, each blade member having upper and lower surfaces and a nose, with the lower surface of the movable blade member being in engagement with the upper surface of the fixed blade member, the fixed blade member having at its nose a notch defined by a shearing edge extending from the upper surface substantially normal thereto and terminating short of the lower surface and an extension surface extending outwardly from said shearing edge substantially normal thereto between the shearing edge and the lower surface, the movable blade member having at the nose thereof a lug extending from the lower surface substantially normal to the lower surface, the lug having a shearing edge extending from the upper surface substantially normal thereto, the arrangement being such that with a wire inserted between the noses and upon movement of the movable blade member, the shearing edge of the lug coacts with the shearing edge of the fixed blade member to crop the wire and upon continued movement, the lug bends the wire.
