Abstract
Abstract An electrical coil which has a bobbin configuration with a terminal-mounting means. The terminal-mounting means includes a separate connector plate for receiving end wires from a coil wound on the bobbin for connection to appropriate terminal leads. The connector plate is snap-fit onto the bobbin at the peripheral edge of the bobbin end discs spanning the channel of the bobbin with the wound coil therein so as to position the connector plate for receiving the coil end wires and/or the terminal leads.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
In an electrical coil having a bobbin coil form with a central portion and a pair of generally parallel end discs at either end of the central portion defining a coil-receiving channel, a coil wound on the central portion of the coil form within said channel and having end wires for connection to terminal leads, the improvement comprising: a separate connector plate receiving the end wires of said coil and said terminal leads; and means for mounting said connector plate between the end discs of the bobbin, including complementary interengaging surfaces on one disc and the corresponding edge of the connector plate, a tab extending from the opposite edge of the connector plate toward the center of the bobbin and means defining a radial slot in the other of said end discs, in which said tab is received and through which an end wire of the coil extends outwardly to the connector plate.
Claim 2
Dependent Claim
153 words
In an electrical coil having a bobbin coil form with a central portion and a pair of generally parallel end discs at either end of the central portion defining a coil-receiving channel, a coil wound on the central portion of the coil form within said channel and having end wires for connection to terminal leads, the improvement comprising: a separate connector plate receiving the end wires of said coil and said terminal leads; and means for mounting said connector plate between the end discs of the bobbin, including complementary interengaging surfaces on one disc and the corresponding edge of the connector plate, a tab extending from the opposite edge of the connector plate toward the center of the bobbin and means defining a radial slot in the other of said end discs, in which said tab is received and through which an end wire of the coil extends outwardly to the connector plate.
Claim 3
Dependent Claim
38 words
The coil of claim 1 in which said discs are circular and the edge of the other disc has a flat surface extending on both sides of said slot, the connector plate being seated on said flat surface.
Claim 4
Dependent Claim
34 words
The coil of claim 1 wherein the complementary interengaging surfaces comprise means defining an aperture in said one disc and a lip on the corresponding edge of the connector plate extending into the aperture.
Claim 5
Dependent Claim
215 words
In an electrical coil having a bobbin coil form with a central portion and a pair of generally parallel end discs at either end of the central portion defining a coil receiving channel, a coil wound on the central portion of said coil form within said channel and having end wires connected to terminal leads, a connector plate having a flat base portion mounted between said end discs for receiving said end wires from said terminal leads, the improvement comprising: a T-shaped boss extending from said base portion generally radially of the bobbin, the T-shaped boss having a cross-shaped portion and a leg portion, the cross portion being oriented generally parallel to said end discs and the leg portion extending at right angles thereto, and a pair of upstanding bosses extending from said base portion, one on each side of the leg portion of said T-shaped boss, spaced from said leg portion and from said cross portion, said terminal leads having exposed wire portions thereof extending at right angles to the leads, one lead being positioned between each of said upstanding bosses and said leg portion, with the exposed wire portions thereof extending around the upstanding bosses and between them and the cross portion of the T-shaped boss, and connected to said coil end wires.
