Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
175 words
A terminal assembly adapted to project through an opening in seal means closing an open end of a housing for an electrical component, the terminal assembly comprising terminal member means including an external connection portion and an internal connection portion, an opening in the internal connection portion and extension means concentric with the opening of the internal connection portion projecting from the internal connection portion, the extension means adapted to project into the opening of the seal means, and means projecting through the opening of the internal connection portion including a portion adapted to assist in retaining tab means of the electrical component, the means including shank means having flute means, the extension means of the internal connection portion in contact with the flute means by moving the extension means relative to the flute means to drive at least some of the flute means outwardly from the shank means, a flanged portion of the shank means engaging with the internal connection portion to lock the means including the shank means to the terminal member means.
Claim 2
Dependent Claim
175 words
A terminal assembly adapted to project through an opening in seal means closing an open end of a housing for an electrical component, the terminal assembly comprising terminal member means including an external connection portion and an internal connection portion, an opening in the internal connection portion and extension means concentric with the opening of the internal connection portion projecting from the internal connection portion, the extension means adapted to project into the opening of the seal means, and means projecting through the opening of the internal connection portion including a portion adapted to assist in retaining tab means of the electrical component, the means including shank means having flute means, the extension means of the internal connection portion in contact with the flute means by moving the extension means relative to the flute means to drive at least some of the flute means outwardly from the shank means, a flanged portion of the shank means engaging with the internal connection portion to lock the means including the shank means to the terminal member means.
Claim 3
Dependent Claim
30 words
The terminal assembly of claim 1, wherein the flute means is a plurality of flutes integral with and elongated in the direction of the longitudinal axis of the shank means.
Claim 4
Dependent Claim
22 words
The terminal assembly of claim 2, wherein the extension means is made from a metal harder than the metal of the flutes.
Claim 5
Dependent Claim
41 words
The terminal assembly of claim 3, wherein the extension means is metal selected from the group including iron and steel, and the flutes are a metal selected from the group including aluminum, aluminum alloys, and copper, silver, gold and their alloys.
Claim 6
Dependent Claim
24 words
The terminal assembly of claim 1, wherein the extension means is aDapted to engage with the wall of the opening of the seal means.
Claim 7
Dependent Claim
60 words
The terminal assembly of claim 5, wherein the means including the shank means is a rivet-like means including base means having a contact surface with a plurality of dimples, and washer means adjacent the contact surface of the base means, the contact surface and washer means adapted to grip and assist in retaining the tab means of the electrical component.
Claim 8
Dependent Claim
30 words
The terminal assembly of claim 6, wherein the external connection portion of the terminal member means is at an angle of about 90* with respect to the internal connection portion.
Claim 9
Dependent Claim
131 words
The terminal assembly of claim 1, wherein the internal connection portion and the external connection portion are at an angle with respect to each other, the means including the shank means is a rivet-like means including a base means having a contact surface with dimple means adapted to assist in retaining the tab means, the shank means projecting from the base means and having the flute means integral with and elongated in the direction of the longitudinal axis of the shank means, the extension means of the internal connection portion in contact with the flute means by moving the extension means relative to the flute means to drive the flute means toward the base means and outwardly from the shank means to occupy more of the opening of the seal means.
Claim 10
Dependent Claim
22 words
The terminal assembly of claim 8, wherein the extension means is a hard metal and the flute means is a soft metal.
Claim 11
Dependent Claim
29 words
The terminal assembly of claim 8, including a washer cooperatively associated with the contact surface of the base of the rivet-like means to assist in retaining the tab means.
Claim 12
Dependent Claim
24 words
The terminal assembly of claim 10, wherein the extension means is adapted to engage with the wall of the opening of the seal means.
Claim 13
Dependent Claim
56 words
A capacitor including anode electrode means and cathode electrode means, dielectric means between the anode electrode means and the cathode electrode means, electrolyte means cooperatively associated with the anode electrode means and the cathode electrode means, tab means contacting one of the electrode means and having a portion retained by the terminal assembly of claim 1.
