Abstract
Abstract A capacitor including an insulating body supporting a conductor assembly. A conductor assembly includes first and second terminal members at opposite ends respectively of the body and a conductive link member extending through the body and electrically connecting the first and second terminal members. A metal strip encircles the exterior of the body adjacent the first terminal member, and the metal strip defines a first capacitor plate while the first conductor defines a second capacitor plate. The dielectric of the capacitor is provided by the material of the body lying between the first terminal and the metal strip.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
253 words
A capacitor for use in a circuit having first and second complementary shaped mating and releasably engageable circuit elements, comprising: an insulating body; a conductor assembly carried by the body and including a first terminal member accessible at one end of said body and including a hollow conductive sleeve arranged to internally receive the first mating circuit element, a second terminal member accessible at the other end of said body and including a spring means plug part arranged to be received in the second mating circuit element, and a conductive rivet means having a width less than the width of said first and second terminal members extending within said body and electrically interconnecting said first and second terminal members; a metal strip on the exterior of said body having a third terminal member connected thereto; said strip constituting a first capacitor plate, said first terminal member constituting a second capacitor plate and said body including a solid dielectric material between said first and second plates and in direct contact with said conductive rivet means; and an outer casing of insulating material about said body leaving said first, second and third terminal members accessible but enclosing at least said metal strip constituting said first capacitor plate, said sleeve having a portion projecting from said body and the outer surface of said projecting portion being encircled by said outer casing, said outer casing being arranged adjacent to said second terminal member to encircle the second mating circuit element engaging said second terminal member in use.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
32 words
A capacitor as claimed in claim 1 wherein the metal strip constituting the first capacitor plate is in the form of a band encircling the body intermediate the ends of the body.
Claim 4
Dependent Claim
29 words
A capacitor as claimed in claim 1 wherein the first terminal member includes a cylindrical region which extends into the body, the cylindrical region defining the second capacitor plate.
Claim 5
Dependent Claim
22 words
A capacitor as claimed in claim 1 wherein the first and second terminal members are disposed with their axes at right angles.
