Solder-on connector for coaxial cable

A method of forming a solder-on end connector upon an exposed end of a coaxial cable, the coaxial cable being of the type having a center conductor surrounded by a dielectric material, and the dielectric material being surrounded by an outer conductor of a predetermined diameter and encased by a protective jacket, the method comprising the steps of:

• a. providing a pin having first and second opposing ends, the first end of the pin having a central bore for receiving the center conductor of the coaxial cable, the first end of the pin having a first pin diameter;
• b. inserting the exposed end of the center conductor of the coaxial cable into the central bore of the first end of the pin;
• c. soldering the first end of the pin to the center conductor of the coaxial cable;
• d. providing an insulator that extends between first and second opposing ends wherein the first end of the insulator has an outer wall having an outer diameter, the first end of the insulator including an opening formed therein defined by an inner wall, and wherein the second end of the insulator has an aperture, the inner wall of the insulator proximate the first end thereof having an inner diameter greater than the first pin diameter,
• e. sliding the aperture of the insulator over the second end of the pin until the first end of the insulator abuts an exposed edge of the outer conductor of the coaxial cable, the second end of the insulator directly contacting the pin, while the inner wall of the insulator proximate the first end thereof is spaced apart from the first end of the pin;
• f. providing a body member that extends between first and second opposing ends along a longitudinal axis, the first end of the body member including a first-end opening leading into a generally cylindrical cavity having an internal diameter commensurate with the predetermined diameter of the outer conductor of the coaxial cable, the second end of the body member including a second-end opening communicating with the generally cylindrical cavity;
• g. sliding the first end of the body member over the second end of the pin, over the insulator, and over the exposed outer conductor of the coaxial cable;
• h. applying solder between the outer conductor of the coaxial cable and the generally cylindrical cavity of the body member;
• and
• i. heating the solder applied in step h. to couple the outer conductor of the coaxial cable with the body member.

A solder-on connector for a coaxial cable, the coaxial cable being of the type having a center conductor surrounded by a dielectric material, and the dielectric material being surrounded by an outer conductor of a predetermined diameter and encased by a protective jacket, the protective jacket of the coaxial cable being made of a thermoplastic material having a characteristic reflow temperature at which it deforms, the solder-on connector comprising in combination:

• a. a body member extending between first and second opposing ends along a longitudinal axis, the first end including a first-end opening leading into a generally cylindrical cavity having an internal diameter commensurate with the predetermined diameter of the outer conductor of the coaxial cable, the second end of the body member including a second-end opening communicating with the generally cylindrical cavity;
• b. a fastener coupled with the body member proximate the second end of the body member, the fastener being adapted to removably engage a mating coaxial connector;
• c. an insulator disposed at least partially within the generally cylindrical cavity of the body member, the insulator having an aperture formed therein and extending generally coaxial with the longitudinal axis of the body member;
• d. a pin having a first end for being electrically coupled with the center conductor of the coaxial cable and having an opposing second end extending within the second-end opening of the body member, at least a portion of the pin passing through, and being supported by, the aperture formed in the insulator, wherein the pin is supported within the body member generally coaxial with the longitudinal axis thereof;
• and
• e. the first-end opening of the body member includes an outermost region having an internal diameter that exceeds the inner diameter of the generally cylindrical cavity for allowing a portion of the protective jacket of the coaxial cable to enter such outermost region, the outermost region of the body member includes an inwardly directed flange proximate the first end of the body member, the inwardly directed flange serving to capture melted portions of the protective jacket of the coaxial cable when the same is heated to its characteristic reflow temperature.
