Abstract
Abstract A coil tray assembly is provided which not only permits a number of loading coils to be more easily packaged, but further permits coil cases of various standard sizes to be constructed using the coil trays. The coil tray is a molded L-shaped plastic tray with either twelve or thirteen terminated coil assemblies inserted and potted therein with an encapsulating compound. This basic coil tray assembly can be used in the construction of either a 6 inch square, 11 X 6 inch rectangular or a 11 inch square coil case. Provisions for wire-wrapped termination of cable leads to coils instead of using special connectors and lead out wires also are provided. Further still, greater coil density with coil cases is possible, and the spaced and orientated coils within the trays eliminate the need for crosstalk plates and/or production tuning of the coils.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
157 words
A coil tray assembly comprising, in combination: a coil tray molded of plastic material and having a plurality of spaced and oriented semi-circular shaped cavities therein for receiving loading coils and a plurality of holes adjacent each of said cavities for receiving therethrough the terminal pins of a terminal block, a terminal block having a base supporting a plurality of terminal pins such that said terminal pins extended from each of the opposite sides thereof, a plurality of loading coils having the ends of the windings thereon coupled with said terminal pins on one side of said base of said terminal block, said loading coils being positioned within said cavities in said coil tray and said terminal pins being extended through said plurality of holes adjacent said cavities so as to project from the bottom of said coil tray, and means hermetically sealing and positionally fixing said loading coils and said terminal blocks in said coil tray.
Claim 2
Dependent Claim
157 words
A coil tray assembly comprising, in combination: a coil tray molded of plastic material and having a plurality of spaced and oriented semi-circular shaped cavities therein for receiving loading coils and a plurality of holes adjacent each of said cavities for receiving therethrough the terminal pins of a terminal block, a terminal block having a base supporting a plurality of terminal pins such that said terminal pins extended from each of the opposite sides thereof, a plurality of loading coils having the ends of the windings thereon coupled with said terminal pins on one side of said base of said terminal block, said loading coils being positioned within said cavities in said coil tray and said terminal pins being extended through said plurality of holes adjacent said cavities so as to project from the bottom of said coil tray, and means hermetically sealing and positionally fixing said loading coils and said terminal blocks in said coil tray.
Claim 3
Dependent Claim
50 words
The coil tray assembly of claim 1, wherein said coil tray is generally L-shaped and has side walls about its perimeter, said side walls being proportioned such that said loading coils do not extend above said side walls, thereby permitting said coil tray assemblies to be stacked one atop another.
Claim 4
Dependent Claim
35 words
The coil tray assembly of claim 2, further including an opening through said coil tray for receiving therethrough a clamping rod in a coil case, for securing said coil tray assembly in a coil case.
Claim 5
Dependent Claim
43 words
The coil tray assembly of claim 3, further including a slot on the end of each of the legs forming said L-shaped coil tray for receiving therethrough alignment bars in a coil case, for aligning said coil tray assembly in a coil case.
Claim 6
Dependent Claim
21 words
The coil tray assembly of claim 4, wherein said loading coils are vertically disposed within said cavities in said coil tray.
Claim 7
Dependent Claim
29 words
The coil tray assembly of claim 2, wherein connections are established with said loading coils by means of said terminal pins projecting through the bottom of said coil tray.
