What is described is a connection element for fastening a metal part to a printed circuit board, wherein the connection element has a first portion, which is formed as a press-fit pin to be pressed into a bore of the printed circuit board, and a second portion, which is formed as a screw to be screwed into the metal part.

Connection element for fastening a metal part to a printed circuit board

Described is a fuse for an electrical circuit, comprising two contact arms, each having at least one connecting pin for inserting into a hole of a printed circuit board, and a spring which connects the two contact arms in an electrically conductive manner. According to this disclosure, it is provided that the spring is fastened to at least one of the two contact arms by means of a fastening means that loses its strength at a trigger temperature of the fuse, wherein the fuse is formed in such a manner that by inserting the connecting pins into holes of a printed circuit board, the spring is loaded such that the spring lifts from the at least one contact arm by spring force as soon as the fastening means loses its strength due to overheating. Moreover, a printed circuit board comprising such a fuse is described.

Fuse for an electrical circuit and printed circuit board having a fuse

The invention relates to a glow plug control device comprising a power transistor for switching the heating current on and off, a control unit for controlling the power transistor, a measuring resistor connected in series with the power transistor for measuring the intensity of a heating current, and a circuit board, which carries the power transistor, the control unit and the measuring resistor. The measuring resistor is connected to the circuit board via pins which are pressed into circuit board holes and which are made of an alloy that has a copper content of at least 80% by weight and a nickel content from 4 to 12% by weight. This disclosure also relates to the use of an alloy having a copper content of at least 80% by weight and a nickel content from 4 to 12% by weight for a pin of a press-in connection in a glow plug control device.
