Abstract
A coaxial electrical cable assembly includes a coaxial electrical terminal having an inner ferrule disposed between an insulator surrounding a central conductor of a coaxial cable and a shield conductor of the coaxial cable and an outer ferrule crimped to the shield conductor and in compressive contact therewith. The outer ferrule defines a pair of crimp wings extending from a first side of a base portion of the outer ferrule and a single crimp wing extending from a second side of the base portion opposite the first side. The single crimp wing is disposed within a gap between the pair of crimp wings.
Claims17
An electrical cable assembly, comprising:
- an electrical terminal having an inner ferrule disposed between an insulator surrounding a central conductor of an electrical cable and a shield conductor of the electrical cable;
- and
- an outer ferrule crimped to the shield conductor and in compressive contact therewith, the outer ferrule defining a pair of crimp wings, both having a trapezoidal shape, extending from a first side of a base portion of the outer ferrule and a single crimp wing having a trapezoidal shape and extending from a second side of the base portion opposite the first side, the single crimp wing, the pair of crimp wings, and the base portion being bent to form a generally cylindrical tubular shape and each of the pair of crimp wings and the single crimp wing having a length equal to at least half of a circumference of the outer ferrule, each crimp wing narrowing continuously from the base portion to its tip, the single crimp wing being wider than a trapezoidal gap between the pair of crimp wings which widens continuously from the base portion to its end, the single crimp wing being disposed within the gap such that mesial edges of the pair of crimp wings are in compressive contact with distal edges of the single crimp wing.
A method of forming an outer ferrule configured to secure an electrical terminal to an electrical cable, the method comprising:
- forming an outer ferrule preform from sheet metal of generally uniform thickness, wherein the outer ferrule preform has a central base portion, defining a pair of crimp wings, both having a trapezoidal shape, extending from a first side of a base portion of the outer ferrule and a single crimp wing having a trapezoidal shape and extending from a second side of the base portion, each crimp wing narrowing continuously from the base portion to its tip, the pair of crimp wings defining a trapezoidal gap therebetween which widens continuously from the base portion to its end, and a width of the single crimp wing being greater than a width of the gap;
- and
- bending the single crimp wing, the pair of crimp wings, and the base portion to form a generally cylindrical tubular shape, each of the pair of crimp wings and the single crimp wing having a length equal to at least half of a circumference of the outer ferrule.
An electrical cable assembly, comprising:
- an electrical terminal having an attachment portion having a pair of crimp wings, both having a trapezoidal shape, extending from a first side of a base portion of the attachment portion and a single crimp wing having a trapezoidal shape and extending from a second side of the attachment portion opposite the first side, the single crimp wing, the pair of crimp wings, and the base portion being bent to form a generally cylindrical tubular shape and each of the pair of crimp wings and the single crimp wing having a length equal to at least half of a circumference of an outer ferrule, each crimp wing narrowing continuously from the base portion to its tip, the single crimp wing being wider than a trapezoidal gap between the pair of crimp wings which widens continuously from the base portion to its end, the single crimp wing configured to be disposed within the gap such that mesial edges of the pair of crimp wings are in compressive contact with distal edges of the single crimp wing.
