Claim 3

The spool claimed in claim 1 wherein said first flange and said flap comprise a single piece of molded plastic.

Claim 4

The spool claimed in claim 2 wherein said opening forms a break in a peripheral edge of said first flange.

Claim 5

The spool claimed in claim 1 including a member extending from and at an angle to said flap such that said member lies across said first and second flanges when said flap is in said closed position, said membeR providing a means for supporting external connections.

Claim 6

A structure for insulating the lead-in end of a wire coil from the lead-out end of a wire coil comprising a spool for mounting the wire coil, said spool comprising an elongated core, first and second flanges axially spaced from one another on said core, said first and second flanges having inside surfaces which define a winding sapce on said core for supporting said wire coil, said first flange having an opening extending from said inside surface to an outside surface of said first flange, said spool being formed of an insulating material, a flap of insulating material extending from said first flange from an axis defined by a chord therof and said flap having first and second surfaces positioned at an angle to one another, said flap having an open position in which said flap forms an angle with said outside surface and a closed position in which said first surface of said flap lies against said outside surface of said first flange and overlies said opening whereby said lead-in end of wire extending from said winding space and passing through said slot may be positioned between the outer surface of said first flange and the first surface of said flap and wherein in said closed position said second surface of said flap lies across the wire coil and rests on peripheral edges of said first and second flanges.

Claim 7

A structure for insulating the lead-in end of a wire coil from the lead-out end of a wire coil comprising a spool for mounting the wire coil, said spool comprising an elongated core, first and second flanges axially spaced from one another on said core, said first and second flanges having inside surfaces which define a winding sapce on said core for supporting said wire coil, said first flange having an opening extending from said inside surface to an outside surface of said first flange, said spool being formed of an insulating material, a flap of insulating material extending from said first flange from an axis defined by a chord therof and said flap having first and second surfaces positioned at an angle to one another, said flap having an open position in which said flap forms an angle with said outside surface and a closed position in which said first surface of said flap lies against said outside surface of said first flange and overlies said opening whereby said lead-in end of wire extending from said winding space and passing through said slot may be positioned between the outer surface of said first flange and the first surface of said flap and wherein in said closed position said second surface of said flap lies across the wire coil and rests on peripheral edges of said first and second flanges.

Claim 8

A structure according to claim 4 further comprising means providing at least one conductive contact terminal on at least one surface of said flap for connecting thereto the external connections of said wire coil.

Claim 9

A spool formed of insulating material comprising two end flanges spaced apart on a core for carrying a wire coil, one portion of one end flange containing a slotted sector and a separate but abutting flap sector overlying said slotted sector, said flap sector being moveable about an axis defined by a chord of said one flange such that in an open position a lead-in end of the wire coil may be passed through the slotted sector, whereas in a closed position the passed lead-in wire is covered by said flap sector overlying said slotted sector.

Claim 10

A spool formed of insulating material comprising two end flanges spaced apart on a core for carrying a wire coil, one portion of one end flange containing a slotted sector and a separate but abutting flap sector overlying said slotted sector, said flap sector being moveable about an axis defined by a chord of said one flange such that in an open position a lead-in end of the wire coil may be passed through the slotted sector, whereas in a closed position the passed lead-in wire is covered by said flap sector overlying said slotted sector.

Claim 11

A spool formed of insulating material comprising two end flanges spaced apart on a core for carrying a wire coil, one sector of one end flange essentially being divided to comprise a slotted sector and a separate but abutting flap sector overlying said slotted sector, said flap sector being hingeably attached to said slotted sector along an axis on said one flange such that in an open position a lead-in end of the wire coil may be passed through the slotted sector, whereas in a closed position the passed lead-in wire is covered by said flap sector overlying said slotted sector.

Claim 12

A spool formed of insulating material comprising two end flanges spaced apart on a core for carrying a wire coil, one sector of one end flange essentially being divided to comprise a slotted sector and a separate but abutting flap sector overlying said slotted sector, said flap sector being hingeably attached to said slotted sector along an axis on said one flange such that in an open position a lead-in end of the wire coil may be passed through the slotted sector, whereas in a closed position the passed lead-in wire is covered by said flap sector overlying said slotted sector.

Claim 13

A spool formed of insulating material comprising two end flanges spaced apart on a core for carrying a wire coil, one end flange having a sector defined by a chord and the periphery beyond said chord, said sector being divided into a component slotted sector and a component flap sector overlying said slotted sector, said flap sector being moveable about an axis defined by said chord such that in an open position a lead-in end of the wire coil may be passed through the slotted sector, whereas in a closed position the passed lead-in wire is covered by said flap sector overlying said slotted sector.

Claim 14

A spool formed of insulating material comprising two end flanges spaced apart on a core for carrying a wire coil, one end flange having a sector defined by a chord and the periphery beyond said chord, said sector being divided into a component slotted sector and a component flap sector overlying said slotted sector, said flap sector being moveable about an axis defined by said chord such that in an open position a lead-in end of the wire coil may be passed through the slotted sector, whereas in a closed position the passed lead-in wire is covered by said flap sector overlying said slotted sector.
