Method for connecting wires to terminals having tangs and cutting the wires at the terminals

Claim 3

The method of claim 1 further comprising the step of gripping said wire segment by gripper means which is controllable to apply different gripping pressures to said wire segment, initially gripping said wire segment with a pressure sufficiently low that said wire segment may be drawn through said gripper means as said wire segment is being looped around said tang and bent around said edge, and increasing the gripping pressure applied to said wire segment by said gripping means after said wire segment is bent over said edge and before said pulling step so that said wire segment is gripped with sufficient pressure that said wire segment will not be drawn through said gripping means when said wire segment is being broken.

Claim 6

The method of claim 3 further comprising the step of gripping said coil lead by gripper means which is controllable to apply different gripping pressures to said coil lead, initially gripping said coil lead with a pressure sufficiently low that said coil lead may be drawn through said gripper means as said coil lead is being looped around said tang and bent around said edge, and increasing the gripping pressure applied to said coil lead by said gripping means after said coil lead is bent over said edge and before said pulling step so that said coil lead is gripped with sufficient pressure that said coil lead will not be drawn through said gripping means when said coil lead is being broken.

Claim 7

For use in the manufacture of electric motor stators of the type comprising a stator core with pole pieces around which wire coils are wound, terminal supports mounted on the stator core, and terminals mounted in and projecting from said terminal, a method for connecting a wire coil lead wire extending from said stator coil past said terminal and having a free end held by clamp means remotely from said stator core, said terminal comprising a sheet member having substantially parallel first and second faces, a pair of side edges joining to said faces to form corners therebetween, and said terminal further comprising a tang projecting from said first face, said method comprising the steps of: gripping said coil lead by pressure-controllable gripper means at a point between said terminal and said free end and nearer said terminal than said free end with a pressure sufficiently low that said coil lead may be drawn through said gripper means; moving said gripper means as needed to lay a portion of said coil lead between one side of said tang and said first face of said terminal, to thereafter loop said coil lead around the other side of said tang, to extend said coil lead past said tang over said first face, to loop said coil lead over one of said side edges, and to extend said coil lead along said second face of said terminal; increasing the gripping pressure applied to said coil lead by said gripper means; and pulling said coil lead with force sufficient that it is stretched and broken at the corner of said terminal between said last mentioned side edge and said second face of said terminal.

Claim 8

For use in the manufacture of electric motor stators of the type comprising a stator core with pole pieces around which wire coils are wound, terminal supports mounted on the stator core, and terminals mounted in and projecting from said terminal, a method for connecting a wire coil lead wire extending from said stator coil past said terminal and having a free end held by clamp means remotely from said stator core, said terminal comprising a sheet member having substantially parallel first and second faces, a pair of side edges joining to said faces to form corners therebetween, and said terminal further comprising a tang projecting from said first face, said method comprising the steps of: gripping said coil lead by pressure-controllable gripper means at a point between said terminal and said free end and nearer said terminal than said free end with a pressure sufficiently low that said coil lead may be drawn through said gripper means; moving said gripper means as needed to lay a portion of said coil lead between one side of said tang and said first face of said terminal, to thereafter loop said coil lead around the other side of said tang, to extend said coil lead past said tang over said first face, to loop said coil lead over one of said side edges, and to extend said coil lead along said second face of said terminal; increasing the gripping pressure applied to said coil lead by said gripper means; and pulling said coil lead with force sufficient that it is stretched and broken at the corner of said terminal between said last mentioned side edge and said second face of said terminal.
