Abstract: An electrical contact includes: a first end; a second end; and a solder cup section formed at the first end. The solder cup section conductively connects to an electric component including a wire, by soldering. The solder cup section has a circumferential wall region with an upper edge defining a solder cup opening at the first end, and a solder cup base, which is arranged opposite the solder cup opening and which defines a base of the solder cup section. The electrical contact is stamped and formed from a metal sheet.

Abstract: A method for joining an electrical terminal pre-populated in a contact carrier and an electrical conductor includes arranging a connection portion of the electrical conductor at a receiving section of the electrical terminal pre-populated in the contact carrier, arranging at least two electrodes on one or more sides of the receiving section of the electrical terminal pre-populated in the contact carrier receiving the connection portion of the electrical conductor, and fusing the connection portion of the electrical conductor and the receiving section of the electrical terminal pre-populated in the contact carrier by using the electrodes to join the electrical conductor and the electrical terminal pre-populated in the contact carrier.

Abstract: A fastening aid for screwing a fastener having a locknut by rotating the fastener around a rotation axis with a predetermined torque includes a sleeve element being attachable around the locknut along the rotation axis, an engaging structure provided at an inner surface of the sleeve and configured to engage with the locknut when the sleeve is attached around the locknut, a clasp element for reversibly closing the sleeve element to a closed state for attaching the sleeve around the locknut, and for reversibly opening the sleeve element to an opened state for detaching the sleeve from the locknut. The fastening aid is configured to allow screwing of the fastener around the rotation axis when exposed to a torque smaller than or equal to the predetermined torque and to prevent screwing the fastener around the rotation axis when the predetermined torque is exceeded.
