Abstract
Abstract An electrical coil assembly having cup core coils and a pair of side flanges defining the coil member winding space and one of these side flanges is radially wider than the other and exceeds the circumference of the cup core coaxially surrounding the coil member. The widened peripheral flange part is only connected with the winding drum and has pliable metal studs fixed to the widened flange part which are displaceable in a direction transverse to the axis of the coil member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
163 words
An electrical coil assembly having cup core coils comprising a winding drum having outwardly extending flanges formed at opposite ends thereof for restriction of a core member winding space wherein one of said flanges is relatively wider than the other and lies in a plane transverse to the axis of said drum and exceeds the circumference of the cup core coaxially positionable over the coil member and wherein said widened flange provides openings for said cup core and serves as a seat for connecting studs extending through the flange and lying in an axis parallel to the axis of said cup core, a pair of bridges interconnecting said widened flange and said drum and providing the only means for interconnecting the widened flange and said drum, wherein said cup core extends over said drum and through the spaces between said drum and said widened flange portion and wherein said interconnecting studs are displaceable in a direction transverse to the axis of said drum.
Claim 2
Dependent Claim
163 words
An electrical coil assembly having cup core coils comprising a winding drum having outwardly extending flanges formed at opposite ends thereof for restriction of a core member winding space wherein one of said flanges is relatively wider than the other and lies in a plane transverse to the axis of said drum and exceeds the circumference of the cup core coaxially positionable over the coil member and wherein said widened flange provides openings for said cup core and serves as a seat for connecting studs extending through the flange and lying in an axis parallel to the axis of said cup core, a pair of bridges interconnecting said widened flange and said drum and providing the only means for interconnecting the widened flange and said drum, wherein said cup core extends over said drum and through the spaces between said drum and said widened flange portion and wherein said interconnecting studs are displaceable in a direction transverse to the axis of said drum.
Claim 3
Dependent Claim
82 words
An electrical coil assembly constructed in accordance with claim 1 wherein said connecting studs are carried in a shouldered portion of said flange which shouldered portion is displaced from the surface of said widened flange serving as a restriction for one end of the winding space of said drum and wherein said winding studs can be bent transverse to the axis of said drum on said shouldered support so as to lie below the plane of the remainder of said widened flange.
Claim 4
Dependent Claim
35 words
An electrical coil assembly constructed in accordance with claim 2 wherein said pairs of bridges extend radially above said shouldered portions of said flange providing means for guiding the winding ends to said connecting studs.
