Abstract
A wire spool is disclosed that includes an elongate barrel that has a first end and a second end that are separated by a wall with an inner surface and an outer surface. A key is disposed on the inner surface of the barrel, wherein a recess is created within the key. A hook slot is disposed within the outer surface of the barrel, the hook slot is located above the recess and receives a start end of a wire to provide insulation thereof. The hook slot also directs a length of wire to be wound out of the hook slot for placement against a spool flange.
Claims17
A wire spool, comprising:
- an elongate barrel having a longitudinal rotational axis, the barrel has a first end and a second end that are separated by a wall with an inner surface and an outer surface;
- a first flange that is toroidally shaped and is substantially orthogonal to the longitudinal rotational axis, the first flange is disposed concentrically surrounding the first end of the barrel;
- a second flange that is toroidally shaped and is substantially orthogonal to the longitudinal rotational axis, the second flange is disposed concentrically surrounding the second end of the barrel;
- a key that is disposed on the inner surface of the barrel, the key is a rectangular prism that extends from the second flange toward the first flange along the longitudinal rotational axis;
- a recess that creates a hole shaped as a rectangular prism within the key, the recess is smaller than the key;
- a hook slot that is disposed within the outer surface of the barrel, the hook slot is located above the recess and receives a wire with a start end and a length of wire to be wound, the hook slot includes,
- a straight segment that directs the start end into the recess in a first direction;
- a transition that receives the length of wire to be wound from the straight segment and directs the length of wire to be wound approximately ninety degrees relative to the first direction, the length of wire to be wound is opposite the start end;
- and
- an exit pocket that receives the length of wire to be wound from the transition and directs the length of wire to be wound out of the hook slot and against the second flange.

A spool that is used to wind a wire with a start end and a length of wire to be wound, comprising:
- an elongate barrel having a longitudinal rotational axis, the barrel has a first end and a second end that are separated by a wall with an inner surface and an outer surface;
- a first flange that is toroidally shaped and is substantially orthogonal to the longitudinal rotational axis, the first flange is disposed concentrically surrounding the first end of the barrel;
- a second flange that is toroidally shaped and is substantially orthogonal to the longitudinal rotational axis, the second flange is disposed concentrically surrounding the second end of the barrel;
- a key that is disposed on the inner surface of the barrel, the key is a rectangular prism that extends from the second flange toward the first flange along the longitudinal rotational axis, the key has a key length along the longitudinal rotational axis;
- a recess that creates a hole shaped as a rectangular prism within the key, the recess is smaller than the key, the recess has a recess length along the longitudinal rotational axis;
- a hook slot that is disposed within the outer surface of the barrel, the hook slot is located above the recess and has a hook slot length along the longitudinal rotational axis, the hook slot includes,
- a straight segment that directs the start end of the wire into the recess in a first direction;
- a transition that receives the length of wire to be wound from the straight segment and directs the length of wire to be wound approximately ninety degrees relative to the first direction, the length of wire to be wound is opposite the start end;
- and
- an exit pocket that receives the length of wire to be wound from the transition and directs the length of wire to be wound out of the hook slot and against the second flange,
- wherein the key length is greater than the recess length and wherein the recess length is greater than the hook slot length.

A hook slot disposed within a barrel of a wire spool, the barrel has an exterior surface and an interior surface, comprising:
- a recess which is disposed between the exterior surface and the interior surface of the barrel;
- a straight segment that receives a start end and a length of wire to be wound, the straight segment includes:
- a first straight segment sidewall;
- a second straight segment sidewall that is substantially parallel to the first straight segment sidewall;
- a floor that is disposed between the first straight segment sidewall and the second straight segment sidewall;
- and
- a void, which is disposed adjacent to the floor to mechanically couple the straight segment to the recess, wherein the start end is directed into the recess via the void in a first direction;
- a transition that receives the length of wire to be wound from the straight segment, the transition directs the length of wire to be wound approximately ninety degrees relative to the first direction;
- and
- an exit pocket that receives the length of wire to be wound from the transition and directs the length of wire to be wound out of the hook slot;
- wherein the distance of the hook slot from the flange to an end wall of the hook slot is less than the distance of the flange to an end wall of the recess;
- and a key which encloses the recess, the key is disposed on the interior surface of the barrel.
