Abstract: A method for determining the quality of a crimped connection between a conductor and a contact includes operating a crimping device to exert a crimping force on the conductor and the contact. From the crimping force curve that occurs during the crimping, a normalized force-distance crimping force curve is derived and a compression area is determined which lies under a reference crimping force curve.

Abstract: A soldering apparatus for connecting solar cells includes an induction heat source to connect cell conducting tracks, provided with soldering medium, with electric conductors. The heat source has a high-frequency generator and an inductor loop in which the flow of a high-frequency current causes a high-frequency magnetic field to induce in the conducting track and in the electric conductor arranged along the conducting track eddy currents that generate the heat that is necessary for the soldering operation.

Each widening affords access to the soldering point for a magnetic-field-neutral pressure foot that presses the conductor onto the conducting track. The inductor loop extends the entire length of the conducting track of the cell upper and lower sides to solder to the conductor in one soldering operation.

Abstract: A method for stripping a cable, the cable having a conductor encompassed by an insulation and extending in a longitudinal direction, includes cutting into the insulation with stripping blades, after which the insulation is removed by sliding the stripping blades in the longitudinal direction. During the removal procedure, the longitudinal position of the stripping blades is detected if it has been determined by a detection device that at least one of the stripping blades has come in contact with the conductor. Based on the longitudinal position of one or more contacts with the conductor, a classification of the cable as adequately or poorly stripped is carried out.
