The spring has a base from which two insertion tabs extend coaxial with the axis and a pressure tab extending from the base perpendicular to the two insertion tables having a pressure prong to provide a radial grounding force for the connector. The insertion tabs of the spring have hook latches extending past the insulator that lock the connector in the panel and the base of the spring has a hole to receive the cable where first and second clamping tabs clampingly lock the cable in the connector. ## Claims ### Claim 1 A connector for connecting an electrical cable to an aperture in an electrical panel, comprising: a one piece spring, a shell, and an insulator collectively having a longitudinal central axis extending there through when the connector is assembled; said spring having a base from which two side insertion tabs bend around the said axis and a pressure tab extending from the base perpendicular to the two side insertion tabs, and said insulator having a joining wall and a springing feature, and said shell having a through opening coaxial with said longitudinal central axis, wherein said insertion tabs springingly retain said spring in said through opening of said shell, and wherein said springing feature retains said insulator in said through opening of said shell; said insertion tabs of said one piece spring having hook latches extending past said shell to snappingly lock the connector in the panel when axially pressed into the aperture; said pressure tab having a pressure prong to provide a radial grounding force for the connector; and said base of said spring further having a hole to receive the cable when axially pressed into the connector, and a first clamping tab and a second clamping tab, and a third clamping tab to clampingly lock the cable in the connector. ### Claim 2 (depends on 1) The connector of claim 1, wherein said spring is made of sheet metal. ### Claim 3 (depends on 1) The connector of claim 1, wherein the panel has wall material proximal to the aperture and said hook latches of said insertion tabs of said spring each have at least one perpendicularly extending barb to grip into the wall material of the panel. ### Claim 4 (depends on 1) The connector of claim 1, wherein the cable has a spiral or helix shaped side and said first clamping tab and said second clamping tab are differently sized to clamp against the spiral or helix shaped side of the cable. ### Claim 5 (depends on 1) The connector of claim 1, wherein the panel has wall material proximal to the aperture and wherein said shell has a stopper to abut the connector against the wall material of the panel. ### Claim 6 (depends on 5) The connector of claim 5, wherein the aperture has a circumference and said insulator is a bridge ring corresponding with the circumference. ### Claim 7 (depends on 1) The connector of claim 1, wherein said springing feature of said insulator is a plurality of legs that snappingly engage with said shell. ### Claim 8 (depends on 1) The connector of claim 1, wherein said insulator has a plurality of legs that aligningly engage with said shell. ### Claim 9 (depends on 1) The connector of claim 1, wherein the first clamping tab, second clamping tab and third clamping tab are not axially aligned within the spring. ### Claim 10 (depends on 1) The connector of claim 1, wherein the cable has a spiral or helix shaped side and said at least one clamping tab includes a first prong and a second prong that are differently directed to clamp against the spiral or helix shaped side of the cable. ### Claim 11 (depends on 1) The connector of claim 1, wherein said springing feature of said insulator is a plurality of legs that snappingly engage with said shell. ### Claim 12 A connector for connecting an electrical cable to an aperture in an electrical panel, comprising: a one piece spring, a shell, and an insulator collectively having a longitudinal central axis extending there through when the connector is assembled; said spring having a base from which two side insertion tabs bend around the longitudinal central axis and a locking tab extending away from each of the side insertion tabs for locking engagement of the spring to the shell; said insulator having a joining wall and a springing feature, and said shell having a through opening coaxial with said longitudinal central axis, wherein said insertion tabs springingly retain said spring in said through opening of said shell, and wherein said springing feature retains said insulator in said through opening of said shell; said insertion tabs of said one piece spring having hook latches extending past said shell to snappingly lock the connector in the panel when axially pressed into the aperture; and said base of said spring further having a hole to receive the cable when axially pressed into the connector, and a first clamping tab, a second clamping tab and a third clamping tab to clampingly lock the cable in the connector; and wherein the spring includes a pressure tab extending from the base perpendicular to the two side insertion tabs, wherein the pressure tab has a pressure prong to provide a radial grounding force for the connector. ### Claim 13 (depends on 12) The connector of claim 12, wherein said spring is made of sheet metal. ### Claim 14 (depends on 12) The connector of claim 12, wherein the panel has wall material proximal to the aperture and said hook latches of said insertion tabs of said spring each have at least one perpendicularly extending barb to grip into the wall material of the panel. ### Claim 15 (depends on 12) The connector of claim 12, wherein the cable has a spiral or helix shaped side and said first clamping tab and said second clamping tab are differently sized to clamp against the spiral or helix shaped side of the cable. ### Claim 16 (depends on 12) The connector of claim 12, wherein the panel has wall material proximal to the aperture and wherein said shell has a stopper to abut the connector against the wall material of the panel. ### Claim 17 (depends on 16) The connector of claim 16, wherein the aperture has a circumference and said insulator is a bridge ring corresponding with the circumference. ### Claim 18 (depends on 12) The connector of claim 12, wherein the first clamping tab, second clamping tab and the third clamping tab are not axially aligned within the spring. ### Claim 19 (depends on 12) The connector of claim 12, wherein the cable has a spiral or helix shaped side and said at least one clamping tab includes a first prong and a second prong that are differently directed to clamp against the spiral or helix shaped side of the cable.
