1. A stator for use in an electrical machine, the stator comprising:
a stator laminated core including a number of stator teeth and a winding wire, wherein the winding wire is continuously wound and forms a number of rotating field windings each arranged on each of the stator teeth to form a number of phases and a portion of the winding wire extends in a tangential direction with respect to a U-shaped insertion pocket of a number of U-shaped insertion pockets; and
an interconnection device provided with the number of U-shaped insertion pockets corresponding to the number of phases, and each of the U-shaped insertion pockets receive an insulation-displacement contact to form an interconnection point between the winding wire and a number of phase connections disposed on a stator end side and include,
a first vertical U-limb and a second vertical U-limb each extending in an axial direction and collectively defining a contact slot disposed between the first vertical U-limb and the second vertical U-limb, wherein the first vertical U-limb is longer than the second vertical U-limb and the first vertical U-limb is disposed forward of the second vertical U-limb with respect to the tangential direction.
