Method for welding a cable to a terminal
First Claim
Patent Images
1. A method of welding a cable to a terminal, wherein the cable comprises multiple strands, the method comprising the steps of:
- aligning the multiple strands on a welding surface of the terminal along a longitudinal axis of the terminal;
pressing the multiple strands to the terminal with a pressing mechanism separate from the terminal, wherein the multiple strands are not crimped by material forming the terminal,making at least one welding connection between the multiple strands and the terminal by applying at least one pulse of a laser directly to an end section of the cable while pressing the multiple strands to the terminal with the pressing mechanism, wherein a first pulse of the laser is applied to the end section of the cable and a diameter of a first impact area of the first pulse of the laser is larger than an overall width of the pressed multiple strands, wherein a second pulse of the laser is applied to the end section of the cable and a diameter of a second impact area of the second pulse of the laser is larger than the overall width of the pressed multiple strands, wherein the first impact area overlaps the second impact area, and wherein a power of the second pulse of the laser is higher than a power of the first pulse of the laser; and
removing the pressing mechanism after making the at least one welding connection between the multiple strands and the terminal.

Abstract
The invention is a welding method for welding a cable to a terminal, the cable comprising multiple strands and an insulating sheath around the multiple strands, the method comprising the steps of removing the insulating sheath from an end section of the cable, pressing the multiple strands to the terminal with a pressing mechanism, and making at least one welding connection between the multiple strands and the terminal by applying at least one pulse of a laser onto the end section of the cable, and removing the pressing mechanism.
