Conduit end fitting
View Patent ↗A conduit end fitting includes a length of conduit having a core wire extending therethrough and a fitting at an end of the length of conduit. An abutment is rotatably secured to the fitting and has an exterior groove configured to be seated on a substantially U-shaped bracket and a central aperture extending therethrough. A swivel guide tube has an aperture through which the core wire extends and extends through the central aperture of the abutment. A flexible joint member secures one end of the swivel guide tube to the abutment such that the swivel guide tube is rotationally fixed with respect to the abutment.

wherein the ball includes a groove formed about its periphery and defining a plurality of recesses, and the flexible joint member is an annular member having a plurality of interior tabs extending radially inwardly from its interior surface, each interior tab received in a recess in the groove.
8. The conduit end fitting of claim 7 , wherein the abutment includes a plurality of axially extending grooves and the flexible joint member includes a plurality of exterior tabs extending radially outwardly from its exterior surface, each exterior tab received in a groove of the abutment.
9. The conduit end fitting of claim 8 , wherein the flexible joint member includes four exterior tabs spaced approximately 90° from one another and four interior tabs spaced approximately 90° from one another.
10. A conduit end fitting comprising, in combination:
a length of conduit having a core wire extending therethrough;
a fitting at an end of the length of conduit;
an abutment rotatably secured to the fitting and having a central aperture and four grooves extending axially along an interior surface of the abutment and spaced approximately 90° from one another;
a swivel guide tube having an aperture through which the core wire extends and extending through the central aperture of the abutment; and
a swivel joint comprising:
a ball at the end of the swivel guide tube;
a groove formed in the ball and defining two pairs of diametrically opposed recesses, the pairs of recesses offset approximately 90° from one another; and
a flexible annular member positioned in the groove and having four interior projections extending radially inwardly and spaced approximately 90° from one another, each interior projection seated in a corresponding recess in the ball, and four exterior projections extending radially outwardly and spaced approximately 90° from one another, each exterior projection received in a groove in the abutment.
11. The conduit end fitting of claim 10 , wherein the fitting comprises:
a molded sleeve secured about an exterior of the end of the length of conduit;
an isolator positioned about the molded sleeve; and
a cap positioned about the isolator.
12. The conduit end fitting of claim 10 , wherein the abutment includes a pair of opposed wings, each wing having a tab configured to be received in a recess formed on the bracket, and an arm extending axially from an end of the wing.
13. A conduit end fitting comprising, in combination:
a length of conduit having a core wire extending therethrough;
a fitting at an end of the length of conduit;
an abutment rotatably secured to the fitting and having an exterior groove configured to be seated on a substantially U-shaped bracket, a central aperture extending therethrough, and a plurality of axially extending grooves formed on an interior surface thereof;
a swivel guide tube having an aperture through which the core wire extends, and extending through the central aperture of the abutment; and
a swivel joint connecting an end of the swivel guide tube to the abutment and comprising:
a ball on the end of the swivel guide tube, a groove formed in an exterior surface of the ball and defining a plurality of recesses; and
a flexible joint member seated in the groove and having a plurality of radially inwardly extending interior tabs, each interior tab seated in a recess, and a plurality of radially outwardly extending exterior tabs, each exterior tab received in an axially extending groove in the abutment.
14. The conduit end fitting of claim 13 , wherein the fitting comprises:
a molded sleeve secured about an exterior of the end of the length of conduit;
an isolator positioned about the molded sleeve; and
a cap positioned about the isolator.
15. The conduit end fitting of claim 13 , wherein the abutment includes a pair of opposed wings, each wing having a tab configured to be received in a recess formed on the bracket, and an arm extending axially from an end of the wing.
16. A conduit end fitting comprising, in combination:
