An electrical connector including such a cable armor stop. ## Claims ### Claim 1 A cable armor stop comprising: a body having an outer shell with a cylindrical shape dimensioned to engage with an electrical connector, the body having an interior cavity formed by an interior surface of the body, the cavity extending through the body between a front side of the body and a rear side of the body, the cavity generally cylindrical in shape with a maximum cross-sectional diameter sufficient to contact a cable sheathing of an electrical cable with a maximum cable sheathing outer diameter in a range of electrical cables with cable sheathing outer diameters between said maximum cable sheathing outer diameter and a minimum cable sheathing outer diameter, the cavity reduced by a radially protruding member extending inwardly such that a terminating end of said radially protruding member is spaced a distance from an opposite side of the interior surface closest to said terminating end, said distance being less than said minimum cable sheathing outer diameter, said distance being approximately 65 percent of the maximum cross-sectional diameter of the cavity, so as to allow electrical conductors of an electrical cable having a cable sheathing outer diameter within said range of cable sheathing outer diameters to pass through said cavity while contacting the cable sheathing of the electrical cable within said range of cable sheathing outer diameters so as to prevent passage of the cable sheathing. ### Claim 2 (depends on 1) The cable armor stop according to claim 1, wherein the radially protruding member has a smooth shape. ### Claim 3 (depends on 2) The cable armor stop according to claim 2, wherein the shape of the radially protruding member does not have small radii that could impede passage or chaffing of electrical conductors. ### Claim 4 (depends on 1) The cable armor stop according to claim 1, wherein the shape of the radially protruding member substantially corresponds to a palatine uvula. ### Claim 5 (depends on 1) The cable armor stop according to claim 1, wherein the outer shell of the body is formed with an annular groove dimensioned for interfitment with a tongue formed on a U-shaped member of an electrical connector body of the electrical connector so as to secure the cable armor stop to the electrical connector. ### Claim 6 (depends on 5) The cable armor stop according to claim 5, wherein the shape of the radially protruding member substantially corresponds to a palatine uvula. ### Claim 7 (depends on 5) The cable armor stop according to claim 5, wherein a perimeter of the interior surface of the body at both the front side and rear side of the body, and a perimeter of the radially protruding member, are smooth so as to minimize abrasion of electrical conductors passing thereby. ### Claim 8 (depends on 7) The cable armor stop according to claim 7, wherein the shape of the radially protruding member substantially corresponds to a palatine uvula. ### Claim 9 (depends on 7) The cable armor stop according to claim 7, fabricated from an electrical insulating material. ### Claim 10 (depends on 9) The cable armor stop according to claim 9, wherein the insulating material is plastic. ### Claim 11 (depends on 1) The cable armor stop according to claim 1, wherein the outer shell includes at least two movable tabs dimensioned for insertion within slots formed in an electrical connector body of the electrical connector at one end of the electrical connector body. ### Claim 12 (depends on 11) The cable armor stop according to claim 11, wherein the shape of the radially protruding member substantially corresponds to a palatine uvula. ### Claim 13 (depends on 11) The cable armor stop according to claim 11, wherein a perimeter of the interior surface of the body at both the front side and rear side of the body, and a perimeter of the radially protruding member, are smooth so as to minimize abrasion of electrical conductors passing thereby. ### Claim 14 (depends on 13) The cable armor stop according to claim 13, wherein the shape of the radially protruding member substantially corresponds to a palatine uvula. ### Claim 15 (depends on 13) The cable armor stop according to claim 13, fabricated from an electrical insulating material. ### Claim 16 (depends on 15) The cable armor stop according to claim 15, wherein the insulating material is plastic. ### Claim 17 (depends on 1) The cable armor stop according to claim 1, wherein the cavity of the body is reduced by two radially protruding members with terminating ends of said radially protruding members facing each other and spaced a distance from each other less than said minimum cable sheathing outer diameter. ### Claim 18 (depends on 17) The cable armor stop according to claim 17, wherein the shape of each radially protruding member substantially corresponds to a palatine uvula. ### Claim 19 An electrical connector comprising: a body having a nipple formed at one end thereof, the nipple including a cable armor stop formed at one end of the nipple, the cable armor stop having a body, the body of the cable armor stop having an interior cavity formed by an interior surface of the body, the cavity extending through the body between a front side of the body and a rear side of the body, the cavity generally cylindrical in shape with a maximum cross-sectional diameter sufficient to contact a cable sheathing of an electrical cable with a maximum cable sheathing outer diameter in a range of electrical cables with cable sheathing outer diameters between said maximum cable sheathing outer diameter and a minimum cable sheathing outer diameter, the cavity reduced by a radially protruding member extending inwardly such that a terminating end of said radially protruding member is spaced a distance from an opposite side of the interior surface closest to said terminating ends, said distance being less than said minimum cable sheathing outer diameter, said distance being approximately 65 percent of the maximum cross-sectional diameter of the cavity, so as to allow electrical conductors of an electrical cable having a cable sheathing outer diameter within said range of cable sheathing outer diameters to pass through said cavity while contacting the cable sheathing of the electrical cable within said range of cable sheathing outer diameters so as to prevent passage of the cable sheathing. ### Claim 20 (depends on 19) The electrical connector according to claim 19, wherein the electrical connector body has a threaded boss and a slot formed in the body, and the electrical connector has a U-shaped retaining member dimensioned to secure the cable sheathing to the electrical connector body when a fastener is threaded into said boss, with the U-shaped retaining member having a portion passing through said slot. ### Claim 21 (depends on 20) The electrical connector according to claim 20, wherein the radially protruding member has a smooth shape. ### Claim 22 (depends on 21) The electrical connector according to claim 21, wherein the shape of the radially protruding member does not have small radii that could impede passage or chaffing of electrical conductors. ### Claim 23 (depends on 22) The electrical connector according to claim 22, wherein the shape of the radially protruding member substantially corresponds to a palatine uvula. ### Claim 24 (depends on 19) The electrical connector according to claim 19, wherein the shape of the radially protruding member substantially corresponds to a palatine uvula. ### Claim 25 (depends on 19) The electrical connector according to claim 19, wherein the cavity of the body is reduced by two radially protruding members with terminating ends of said radially protruding members facing each other and spaced a distance from each other less than said minimum cable sheathing outer diameter. ### Claim 26 (depends on 25) The electrical connector according to claim 25, wherein the shape of each radially protruding member substantially corresponds to a palatine uvula.
