Abstract
Abstract An anode structure attached to free end of an insulated high-tension lead for engagement with a CRT anode button. The anode structure has a radioactive rays shielding portion for shielding radioactive rays emanating from the anode button, an engaging portion for insertion into the anode button and a lead holding portion for holding the insulated high-tension lead.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
326 words
A CRT anode cap which is provided with an insulated high-tension lead, an anode structure electrically connected with the free end of the insulated high-tension lead for engagement with a CRT anode button, and an insulating cap provided at one end portion of the insulated high-tension lead for housing the anode structure, wherein the anode structure has a first conductive plate member, second and third conductive plate members extending from left and right free end portions of the first conductive plate member and folded back to the right and the left, respectively, to underlie the first conductive plate member in opposing relation thereto, fourth and fifth conductive plate members extending downwardly from the rear free end portions of the second and third conductive plate members, respectively, and sixth and seventh conductive plate members extending from the front and rear free end portions of the first conductive plate member, respectively; wherein the fourth conductive plate member has, in its lower left portion, a first anode button engaging piece provided with a first stepped portion extending outwardly to the left and a first slope extending down therefrom to the right, and a first flange receiving facet extending upwardly from the first stepped portion; wherein the fifth conductive plate member has, in its lower right portion, a second anode button engaging piece provided with a second stepped portion extending outwardly to the right and a second slope extending down therefrom to the left, and a second flange receiving facet extending upwardly from the second stepped portion; wherein the fourth and fifth conductive plate members constitute an engaging portion for engagement with the CRT anode button; wherein the first, second and third conductive plate members constitute a radioactive rays shielding portion for shielding radioactive rays emanating from the side of the CRT anode button; wherein the sixth conductive plate members is electrically connected with the insulated high-tension lead; and wherein the seventh conductive plate member holds the insulated high-tension lead.
Claim 2
Dependent Claim
326 words
A CRT anode cap which is provided with an insulated high-tension lead, an anode structure electrically connected with the free end of the insulated high-tension lead for engagement with a CRT anode button, and an insulating cap provided at one end portion of the insulated high-tension lead for housing the anode structure, wherein the anode structure has a first conductive plate member, second and third conductive plate members extending from left and right free end portions of the first conductive plate member and folded back to the right and the left, respectively, to underlie the first conductive plate member in opposing relation thereto, fourth and fifth conductive plate members extending downwardly from the rear free end portions of the second and third conductive plate members, respectively, and sixth and seventh conductive plate members extending from the front and rear free end portions of the first conductive plate member, respectively; wherein the fourth conductive plate member has, in its lower left portion, a first anode button engaging piece provided with a first stepped portion extending outwardly to the left and a first slope extending down therefrom to the right, and a first flange receiving facet extending upwardly from the first stepped portion; wherein the fifth conductive plate member has, in its lower right portion, a second anode button engaging piece provided with a second stepped portion extending outwardly to the right and a second slope extending down therefrom to the left, and a second flange receiving facet extending upwardly from the second stepped portion; wherein the fourth and fifth conductive plate members constitute an engaging portion for engagement with the CRT anode button; wherein the first, second and third conductive plate members constitute a radioactive rays shielding portion for shielding radioactive rays emanating from the side of the CRT anode button; wherein the sixth conductive plate members is electrically connected with the insulated high-tension lead; and wherein the seventh conductive plate member holds the insulated high-tension lead.
Claim 3
Dependent Claim
100 words
A CRT anode cap according to claim 1 wherein the sixth conductive plate member is formed by folding back the front free end portion of the first conductive plate member at the center thereof to overlie it in opposing relation thereto and has first and second core conductor holding pieces formed by bending down the left and right free end portions of the backwardly extending portion of the sixth conductive plate member, respectively, and wherein the seventh conductive plate member has first and second high-tension lead holding pieces formed by bending up its left and right free end portions, respectively.
Claim 4
Dependent Claim
94 words
A CRT anode cap according to claim 1 wherein the sixth conductive plate member is formed by folding back the front free end portion of the first conductive plate member at the center thereof to lie between it and the second and third conductive plate members and has first and second core conductor holding pieces formed by bending up its left and right free end portions, respectively, and wherein the seventh conductive plate member has first and second high-tension lead holding pieces formed by bending down its left and right free end portions, respectively.
