Abstract
Abstract An encapsulated chip capacitor is made by inserting capacitor bodies between two channels of L-shaped cross-section, electrically connecting the capacitor cathodes to one channel and the anodes to the other thus providing terminals, filling the resulting assembly with insulating encapsulant, curing it, and separating the cured assembly into individual chip capacitors.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
149 words
An encapsulated chip capacitor comprising a pair of terminals with a substantially L-shaped cross-section and each having a vertical plate and a horizontal plate meeting in a right angle along a common edge, a capacitor body with an anode and a cathode encapsulated in an insulating material and having an anode lead extending from one end thereof, one of said terminals electrically connected to said cathode and the other to said anode, said horizontal plate of each of said terminals facing each other and extending partway along the same side of said encapsulated body on the outside thereof contiguous therewith and spaced from each other, said vertical plates extending along the outside of opposite ends of said body and contiguous therewith, said vertical plate connected to said anode having a slot partway down said vertical plate from the top thereof toward the horizontal plate and recieving said anode lead.
Claim 2
Dependent Claim
149 words
An encapsulated chip capacitor comprising a pair of terminals with a substantially L-shaped cross-section and each having a vertical plate and a horizontal plate meeting in a right angle along a common edge, a capacitor body with an anode and a cathode encapsulated in an insulating material and having an anode lead extending from one end thereof, one of said terminals electrically connected to said cathode and the other to said anode, said horizontal plate of each of said terminals facing each other and extending partway along the same side of said encapsulated body on the outside thereof contiguous therewith and spaced from each other, said vertical plates extending along the outside of opposite ends of said body and contiguous therewith, said vertical plate connected to said anode having a slot partway down said vertical plate from the top thereof toward the horizontal plate and recieving said anode lead.
Claim 3
Dependent Claim
37 words
An encapsulated chip capacitor according to claim 1 wherein the extremities of said horizontal and said vertical plates opposite said common edge are bent inwardly forming locking lips and said lips are embedded in said insulating material.
Claim 4
Dependent Claim
35 words
An encapsulated chip capacitor according to claim 2 wherein said locking lips of said vertical plate are embedded in said insulating material on the side opposite that bearing the horizontal plate and adjacent said ends.
Claim 5
Dependent Claim
35 words
An encapsulated chip capacitor according to claim 2 wherein said slot also extends through one of said locking lips and said anode lead is welded to said terminal adjacent the lower end of said slot.
Claim 6
Dependent Claim
21 words
An encapsulated chip capacitor according to claim 1 wherein said cathode is connected to its terminal by solder or conductive adhesive.
