Abstract

Abstract A coil plate assembly having a pair of coil plates with an electrical coil interposed therebetween to position the coil in a molding die for encapsulation in an insulating material. The coil plates each have a pair of side shrouds extending alongside the coil and a boss is formed on the remote end of each shroud. A terminal clasp encircles each pair of bosses of adjacent shrouds to connect the shrouds of the two plates together. In addition, the terminal clasps are electrically connected to the coil and extend outward from the coil plates to act as terminals for making connection in a circuit.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 167 words
In a coil plate assembly for a coil having opposite ends and an opening extending between the ends, the combination comprising: a pair of coil plates between which the coil is disposed, such plates each having: an open center panel portion lying over an end of the coil with the open center overlying the coil opening, alignment lugs extending from the panel portion into the coil opening to position the panel portion with the coil, a pair of side shrouds at opposite margins of the panel portion that turn and extend alongside coil sides, and that have outer ends that abut shrouds of the other coil plate, and a protruberance at the outer end of each side shroud that is positioned adjacent a protruberance of an abutting side shroud of the other coil plate; and a pair of terminals, each having a clasp portion encircling adjacent protruberances of abutting side shrouds to capture the same in position, and a projecting extremity for making connection in a circuit.
Claim 2
Dependent Claim 167 words
In a coil plate assembly for a coil having opposite ends and an opening extending between the ends, the combination comprising: a pair of coil plates between which the coil is disposed, such plates each having: an open center panel portion lying over an end of the coil with the open center overlying the coil opening, alignment lugs extending from the panel portion into the coil opening to position the panel portion with the coil, a pair of side shrouds at opposite margins of the panel portion that turn and extend alongside coil sides, and that have outer ends that abut shrouds of the other coil plate, and a protruberance at the outer end of each side shroud that is positioned adjacent a protruberance of an abutting side shroud of the other coil plate; and a pair of terminals, each having a clasp portion encircling adjacent protruberances of abutting side shrouds to capture the same in position, and a projecting extremity for making connection in a circuit.
Claim 3
Dependent Claim 45 words
A coil plate assembly as in claim 1 in which each of said protruberances has an overhanging lip and a catch, and each terminal clasp portion slides under the lip and is held in place by the catch to temporarily maintain the parts in position.
Claim 4
Dependent Claim 17 words
A coil plate assembly as in claim 1 wherein the assembly is encapsulated in a molding material.
Claim 5
Dependent Claim 145 words
In a coil plate assembly to position a coil in a molding die cavity for encapsulation in an insulating material, the combination comprising: a pair of coil plates between which the coil is disposed; each plate including: an end panel lying over the coil end, die contact means on the end panel to space said assembly from die cavity walls, a pair of side shrouds at opposite ends of the panel and each extending alongside of the coil, and a boss formed on one end of each side shroud for spacing said assembly from the sidewalls of said cavity; and a pair of locking means each embracing the bosses of the shrouds on one side of the coil to connect the coil support plates together, which means are electrically connected with the coil ends and have terminal portions which project outward from the coil plates.
Claim 6
Dependent Claim 145 words
In a coil plate assembly to position a coil in a molding die cavity for encapsulation in an insulating material, the combination comprising: a pair of coil plates between which the coil is disposed; each plate including: an end panel lying over the coil end, die contact means on the end panel to space said assembly from die cavity walls, a pair of side shrouds at opposite ends of the panel and each extending alongside of the coil, and a boss formed on one end of each side shroud for spacing said assembly from the sidewalls of said cavity; and a pair of locking means each embracing the bosses of the shrouds on one side of the coil to connect the coil support plates together, which means are electrically connected with the coil ends and have terminal portions which project outward from the coil plates.
Claim 7
Dependent Claim 58 words
A coil plate assembly as in claim 4 in which the shrouds of one plate extend toward the shrouds of the other plate to abut against one another, and the locking means comprises a clasp portion with an opening in which the bosses of the abutting shrouds are received, and a projection that extends outward from the shrouds.
Claim 8
Dependent Claim 27 words
A coil plate assembly as in claim 4 in which eacH end panel has a central aperture and alignment means which align said coil with the panel.
Claim 9
Dependent Claim 33 words
A coil plate assembly as in claim 6 in which the alignment means comprises a plurality of lugs that protrude from the periphery of each panel aperture to extend partially into said coil.
Claim 10
Dependent Claim 207 words
In a coil plate assembly for positioning a coil in a die cavity for encapsulation in an insulating material, the combination comprising: a pair of coil plates between which the coil is disposed, and each having a center panel with two side members that extend alongside the coil to abut with side members of the other coil plate, each side member has a boss at a remote end that protrudes above said side member with a front inclined face, an opposite rear inclined face, and a lip above said front face, and bosses of two abutting side members match with one another to define a generally rectangular outline; and a pair of terminal clasps, each electrically connected to the coil and each having a clasp portion with a rectangular opening that conforms to the outline of two matching bosses, and a connection end, said clasp portion is adapted to hook under the lips of two matching bosses and pivot down the opposite inclined faces of said matching bosses to seat flat upon the side members associated with said matching bosses, snugly clamping the matching bosses together, said connection end extends outward from said side members and serves as a terminal for connecting said coil into a circuit.
Claim 11
Dependent Claim 207 words
In a coil plate assembly for positioning a coil in a die cavity for encapsulation in an insulating material, the combination comprising: a pair of coil plates between which the coil is disposed, and each having a center panel with two side members that extend alongside the coil to abut with side members of the other coil plate, each side member has a boss at a remote end that protrudes above said side member with a front inclined face, an opposite rear inclined face, and a lip above said front face, and bosses of two abutting side members match with one another to define a generally rectangular outline; and a pair of terminal clasps, each electrically connected to the coil and each having a clasp portion with a rectangular opening that conforms to the outline of two matching bosses, and a connection end, said clasp portion is adapted to hook under the lips of two matching bosses and pivot down the opposite inclined faces of said matching bosses to seat flat upon the side members associated with said matching bosses, snugly clamping the matching bosses together, said connection end extends outward from said side members and serves as a terminal for connecting said coil into a circuit.
Claim 12
Dependent Claim 84 words
A coil plate assembly as in claim 8 in which each boss has a flexible rib at a rear corner and has a catch protruding from the flexible rib, and the ribs of said matching bosses are spaced from one another to allow the ribs to be slightly deflected inward as the clasp portion of the terminal clasp engages and slides over the catches of the matching bosses while pivoting down upon the side members, said catches thereafter maintaining the terminal clasp in place.
