Abstract
Abstract An A.C. anti-radiation choke coil for a device such as a television set is inserted in a metal can and positioned and insulated therein by a hinged container of insulating material that closely encloses the choke coil; each section of the hinged container is provided with a part of a tubular extension which, when the container is closed, provides a full tubular conduit for the leads of the coil, spacing the leads, electrically and mechanically, from the edges of the opening in the can through which the leads extend.

Claim 1
Independent Claim
114 words
In a toroidal choke coil encased in a metal container; an opening in the container; said coil having leads; said leads extending through said opening in the container; the improvement comprising: an insulating receptacle receiving said toroidal choke coil, said insulating receptacle comprising two sections enclosing said coil; said sections of said insulating receptable encasing and positioning said coil between them; said combined sections fitting within said metal container; each section of said insulating receptacle being provided with a part tubular extension; said part tubular extensions of each said sections combining to form a tubular member; said leads extending through said tubular member, said tubular member extendng through said opening in said metal container.
Claim 2
Dependent Claim
114 words
In a toroidal choke coil encased in a metal container; an opening in the container; said coil having leads; said leads extending through said opening in the container; the improvement comprising: an insulating receptacle receiving said toroidal choke coil, said insulating receptacle comprising two sections enclosing said coil; said sections of said insulating receptable encasing and positioning said coil between them; said combined sections fitting within said metal container; each section of said insulating receptacle being provided with a part tubular extension; said part tubular extensions of each said sections combining to form a tubular member; said leads extending through said tubular member, said tubular member extendng through said opening in said metal container.
Claim 3
Dependent Claim
99 words
The toroidal choke coil of claim 1 in which said sections forming said insulating receptacle are of compressible material; the said coil being positioned in said metal container and insulated therefrom; said tubular member having a detent member passing through said hole in said metal container from the interior of said metal container to the exterior thereof; said detent flexing as said tubular member is forced through said hole and engaging the outer side of said container to resist withdrawal of said insulating receptacle from said metal container and to position said coil and insulating receptacle in said container.
Claim 4
Dependent Claim
37 words
The toroidal coil of claim 2 in which the said sections of said insulating receptacle are hinged together; the part tubular extension of each said section extending from each section at the side thereof opposite the hinge.
