Abstract
A laminated cable includes a metal laminate surrounding a cable core having first and second ends. Solder is applied adjacent the ends of the laminate, and is heated and subsequently cooled to form a metal seal. The solder can be melted in a plastic jacketing extruder as the extruder applies a plastic jacket over the metal laminate.
Claims17
A cable comprising:
- a cable core;
- a metallic jacket disposed radially outward relative to the core, the jacket having a first end and second end proximate to the first end, wherein at least a portion of the first end overlaps at least a portion of the second end;
- and
- a seal including solder in contact with the first and second ends, wherein the seal is disposed radially inward of and in overlapping relation to both the first and second ends across the overlap of the first and second ends.

A method of making cable, comprising:
- at least partially surrounding a cable core with a metallic laminate having a first circumferential end and second circumferential end, wherein at least a portion of the first circumferential end overlaps at least a portion of the second circumferential end;
- disposing solder adjacent to the first circumferential end and second circumferential end, wherein the solder is disposed radially inward of and in overlapping relation to both the first and second circumferential ends;
- and,
- forming a seal including the solder in contact with the first circumferential end and second circumferential end across the overlap of the first and second circumferential ends.
1 more element
An apparatus, comprising:
- an elongate cable core extending from an input side of a heat source to an output side of the heat source;
- a metallic laminate at least partially surrounding the cable core and having a first circumferential end and second circumferential end, wherein at least a portion of the first circumferential end overlaps at least a portion of the second circumferential end;
- solder disposed proximate to at least one of the first circumferential end and the second circumferential end, wherein the solder is disposed radially inward of and in overlapping relation to both the first and second circumferential ends;
- and
- a solder seal in contact with the first circumferential end and the second circumferential end across the overlapping portions of the first and second circumferential ends, the solder seal extending along a longitudinal axis of the core from proximate to the heat source to the output side of the heat source.
