Field coil terminal connector for stator assemblies

Claim 2

A terminal connector for use with a stator core of an electrical motor, the stator core having inner arcuate wall portions, and an outer wall having flat portions, a pole portion extending inwardly from the inner arcuate walls thereof and a field coil wound about the pole portion and having terminal ends, said terminal connector comprising: an elongated generally flat body portion having inner and outer arcuate walls and spaced ends; at least two depending lug means extending fixedly in one direction from said inner arcuate walls in spaced relationship with each other and being arcuately shaped so as to be complementary to the inner arcuate wall portions of the core on the opposite sides of the pole portion; exterior flange means including an elongated generally planar wall portion which is angularly disposed relative to said body portion and spaced from said inner wall of said body portion and depending fixedly in said one direction so as to meet said outer arcuate wall of said body portion at two points, said exterior flange means being disposed generally between said depending lug means adjacent said outer arcuate wall of said body portion in a position to engage the flat portion of the outer wall of the stator core, said depending lug means and said exterior flange means being for cooperating with each other and with the stator core to frictionally and securely retain said terminal connector on the stator core adjacent to the pole portion of the stator core, and in a predetermined alignment relative to the stator core; and terminal well means disposed on said body portion adjacent each said end of said body portion, said terminal well means including means for receiving the terminals of the field coil.

Claim 3

The terminal connector of claim 1 in which said body portion of said terminal connector defines an arc of not greater than approximately 120°.

Claim 4

In combination, the terminal connector of claim 1 and a stator core for an electrical motor, said stator core comprising: a field core having inner arcuate wall portions, an outer wall and an end face portion, said outer wall having spaced arcuate portions and generally planar portions, said arcuate portions being connected by said generally planar portions, stator pole means disposed inwardly of said inner walls, winding groove means provided between said pole means and said inner wall portions of said field core, and stator coil means wound within said winding groove means and said terminal connector being mounted adjacent said stator pole means on said end face portion of said field core, said depending lug means and said exterior flange means cooperating with each other and with said field core to frictionally retain said body portion securely on said field core adjacent to said pole means of said field core and with a predetermined alignment relative to said field core.

Claim 5

A terminal connector for use with a stator core of an electrical motor, the stator core having inner and outer arcuate wall portions, a pole portion extending inwardly from said inner arcuate wall portions, an end face perpendicular to said wall portions having an aperture adjacent said pole portion, and a field coil wound about said pole portion and having terminal ends, said terminal connector comprising: an elongated generally flat body portion having inner and outer arcuate edges and spaced ends; at least two depending lug means extending fixedly in one direction from said outer arcuate edges in spaced relationship with each other and being arcuately shaped so as to be complementary to said outer arcuate wall portions of said core on the opposite sides of said pole portion; two retention posts extending from said body portion and spaced from said inner arcuate edge of said body portion and from said outer arcuate edge of said body portion and depending fixedly in said one direction toward said end face, said retention posts being disposed generally between said depending lug means in a position to engage said aperture in said end face, said retention posts extending slightly away from each other and being resilient, and pressing resiliently against the sides of said aperture to frictionally and securely retain said terminal connector on said end face adjacent to said pole portion, said depending lug means cooperating with said retention posts and said stator core to maintain said terminal connector in a predetermined alignment relative to said stator core; and terminal well means disposed on said body portion adjacent each said end of said body portion, said terminal well means including means for receiving the terminals of said field coil.

Claim 6

A terminal connector for use with a stator core of an electrical motor, the stator core having inner and outer arcuate wall portions, a pole portion extending inwardly from said inner arcuate wall portions, an end face perpendicular to said wall portions having an aperture adjacent said pole portion, and a field coil wound about said pole portion and having terminal ends, said terminal connector comprising: an elongated generally flat body portion having inner and outer arcuate edges and spaced ends; at least two depending lug means extending fixedly in one direction from said outer arcuate edges in spaced relationship with each other and being arcuately shaped so as to be complementary to said outer arcuate wall portions of said core on the opposite sides of said pole portion; two retention posts extending from said body portion and spaced from said inner arcuate edge of said body portion and from said outer arcuate edge of said body portion and depending fixedly in said one direction toward said end face, said retention posts being disposed generally between said depending lug means in a position to engage said aperture in said end face, said retention posts extending slightly away from each other and being resilient, and pressing resiliently against the sides of said aperture to frictionally and securely retain said terminal connector on said end face adjacent to said pole portion, said depending lug means cooperating with said retention posts and said stator core to maintain said terminal connector in a predetermined alignment relative to said stator core; and terminal well means disposed on said body portion adjacent each said end of said body portion, said terminal well means including means for receiving the terminals of said field coil.

Claim 7

The terminal connector of claim 1 in which said body portion of said terminal connector defines an arc of not greater than approximately 120°.

Claim 8

In combination, the terminal connector of claim 1 and a stator core for an electrical motor, said stator core comprising: a field core having inner and outer arcuate wall portions, stator pole means disposed inwardly of said inner arcuate wall portions, an end face portion perpendicular to said wall portions and having an aperture adjacent said stator pole means, winding groove means provided between said pole means and said inner arcuate wall portions, and stator coil means wound within said winding groove means, said terminal connector being mounted adjacent said stator pole means on said end face portion of said field core, said retention posts extending slightly away from each other and being resilient and pressing resiliently against the sides of said aperture to frictionally retain said body portion securely on said field core adjacent to said pole means of said field core, and said depending lug means cooperating with said retention posts and said field core to maintain said terminal connector in a predetermined alignment relative to said field core.
