Abstract
Abstract An improved feed through capacitor for radio frequency suppression adapted for universal connection between a source of supply and each utilization device in a vehicle. A conventional capacitive winding is encapsulated in a non-conductive container. A rigid conductive blade having opposite male and female ends of the plug-in type extends through the winding and into the encapsulated container. The male end emerges from the encapsulated container at one end thereof and the female end terminates electrically accessible of the encapsulating material at the other end thereof. A flexible grounding lead is connected to the conventional winding and extends through the encapsulation and outwardly therefrom. The blade supports the entire encapsulated capacitor for universal mounting.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
In a feed-through capacitor having a conventional winding of the type for radio frequency supression, the improvement comprising: an elongated flat rigid conductive blade extending through said winding; said blade having a male end and a female end externally of said winding and at opposite ends thereof; a flexible conductive grounding lead connected to one end of said winding and having a free opposite end; and said winding, said blade and said flexible conductive lead being encapsulated in a non-conductive material with the male blade end and female blade end and free end of said flexible conductive lead all electrically accessible relative to said encapsulation; said conductive blade for electrically interconnecting said capacitor in a circuit and for rigidly supporting said capacitor.
Claim 2
Dependent Claim
122 words
In a feed-through capacitor having a conventional winding of the type for radio frequency supression, the improvement comprising: an elongated flat rigid conductive blade extending through said winding; said blade having a male end and a female end externally of said winding and at opposite ends thereof; a flexible conductive grounding lead connected to one end of said winding and having a free opposite end; and said winding, said blade and said flexible conductive lead being encapsulated in a non-conductive material with the male blade end and female blade end and free end of said flexible conductive lead all electrically accessible relative to said encapsulation; said conductive blade for electrically interconnecting said capacitor in a circuit and for rigidly supporting said capacitor.
Claim 3
Dependent Claim
48 words
The invention as defined in claim 1 and further including a metallic washer at each end of said conventional winding; said washer having a slot therein and said blade extending through the slot in each washer; and said flexible conductive lead being connected to one of said washers.
Claim 4
Dependent Claim
29 words
The invention as defined in claim 1 wherein, said male blade end and said femle blade end and said flexible conductive lead all extend outwardly free of said encapsulation.
Claim 5
Dependent Claim
35 words
The invention as defined in claim 1 wherein, said male blade end and said flexible conductive lead extend outwardly of said encapsulation and said female blade end is flush with the end of said encapsulation.
Claim 6
Dependent Claim
49 words
The invention as defined in claim 1 wherein, said male blade end and said flexible conductive lead extend outwardly of said encapsulatin and said female blade end is recessed inwardly from the end of said encapsulation, said encapsulation being open to provide electrical access to said female blade end.
