Abstract
Abstract An internally threaded insert having intersecting faces about its axis is positioned in a keyed aperture formed in a cover for a capacitor. This provides an antitwist characteristic between the insert and the walls of the aperture to facilitate a seal between the two. An electrical terminal can then be threaded into the insert to electrically connect it to an internal lead of the capacitor. An elastic bushing is also carried in the keyed aperture to provide a seal. The cover has a rib extending around its periphery to engage a capacitor housing, the rib providing a seal.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
105 words
A capacitor cover and terminal connection which comprises: a disc fabricated of an electrically insulative material, at least one aperture in said disc, keying means in a first portion of said aperture, an elastic bushing fabricated of an electrically insulative material carried in a second portion of said aperture, a metal insert extending through said bushing and having an outer face adapted to engage said keying means to thereby provide an antitwist characteristic between said disc and said insert, receiving means within said insert adapted to receive an electrical terminal, and retaining means holding an internal electrical lead into electrical contact with said metal insert.
Claim 2
Dependent Claim
105 words
A capacitor cover and terminal connection which comprises: a disc fabricated of an electrically insulative material, at least one aperture in said disc, keying means in a first portion of said aperture, an elastic bushing fabricated of an electrically insulative material carried in a second portion of said aperture, a metal insert extending through said bushing and having an outer face adapted to engage said keying means to thereby provide an antitwist characteristic between said disc and said insert, receiving means within said insert adapted to receive an electrical terminal, and retaining means holding an internal electrical lead into electrical contact with said metal insert.
Claim 3
Dependent Claim
26 words
A capacitor cover and terminal connection according to claim 1 wherein said elastic bushing is fabricated of a thermal plastic material or a thermal setting material.
Claim 4
Dependent Claim
21 words
A capacitor cover and terminal connection according to claim 1 wherein said keying means comprises flat intersecting walls of said aperture.
Claim 5
Dependent Claim
18 words
A capacitor cover and terminal connection according to claim 3 wherein said flat intersecting walls provide a hexagon.
Claim 6
Dependent Claim
17 words
A capacitor cover and terminal connection according to claim 1 wherein said receiving means includes internal threads.
Claim 7
Dependent Claim
18 words
A capacitor cover and terminal connection according to claim 1 wherein said retaining means includes a rivet head.
Claim 8
Dependent Claim
21 words
A capacitor cover and terminal connection according to claim 1 further including a rib extending from a periphery of said disc.
