Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
147 words
An inductor comprising: (a) a core having two opposing ends; (b) a winding wound about the core; (c) a pair of connector electrodes disposed on the ends of the core; (d) a pair of terminals connected to the connector electrodes and extending downwardly therefrom, each terminal having a connector finger centrally extending from an upper portion of the terminal for connection to one of the connector electrodes and a pair of spaced apart support fingers parallely extending from an intermediate portion of the terminal supporting the core; (e) a covering of molded insulating resin encapsulating the winding, core, and the upper and intermediate portions of the terminals, a lower portion of each terminal protruding through the covering and being bent horizontally along a portion of the bottom of the covering and upwardly along and in contact with at least a portion of the side of the covering.
Claim 2
Dependent Claim
147 words
An inductor comprising: (a) a core having two opposing ends; (b) a winding wound about the core; (c) a pair of connector electrodes disposed on the ends of the core; (d) a pair of terminals connected to the connector electrodes and extending downwardly therefrom, each terminal having a connector finger centrally extending from an upper portion of the terminal for connection to one of the connector electrodes and a pair of spaced apart support fingers parallely extending from an intermediate portion of the terminal supporting the core; (e) a covering of molded insulating resin encapsulating the winding, core, and the upper and intermediate portions of the terminals, a lower portion of each terminal protruding through the covering and being bent horizontally along a portion of the bottom of the covering and upwardly along and in contact with at least a portion of the side of the covering.
Claim 3
Dependent Claim
33 words
An inductor according to claim 1 in which the core is generally dumbbell-shaped and the winding is wound thereon into a coil, the ends of the coil being connected to the connector electrodes.
Claim 4
Dependent Claim
26 words
An inductor according to claim 1 or 2 in which the upwardly folded portion of each terminal has a height less than that of the covering.
