Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A glow plug control device, comprising: a power transistor for switching 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; wherein the measuring resistor is connected to the circuit board via pins which are press-fit 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; whereby the change in resistance of the pins as a function of temperature is low and the mechanical properties of the pins are enhanced for a press-fit connection. 2. The glow plug control device according to claim 1 , wherein the alloy has a copper content of at least 85% by weight. 3. The glow plug control device according to claim 1 , wherein the alloy has a copper content of at least 88% by weight. 4. The glow plug control device according to claim 1 , wherein the alloy contains less than 10% by weight of other alloy constituents. 5. The glow plug control device according to claim 1 , wherein the alloy contains less than 5% by weight of other alloy constituents. 6. The glow plug control device according to claim 1 , wherein the alloy contains less than 3% by weight of other alloy constituents. 7. The glow plug control device according to claim 1 , wherein the alloy has a nickel content from 6 to 10% by weight. 8. The glow plug control device according to claim 1 , wherein the alloy has a nickel content from 8 to 10% by weight. 9. The glow plug control device according to claim 1 , wherein the alloy is CuNi6, CuNi10, CuNi10Fe1Mn or CuNi9Sn2. 10. The glow plug control device according to claim 1 , wherein the alloy does not contain any alloy constituent in an amount greater than 2% by weight other than copper and nickel. 11. The glow plug control device according to claim 1 , wherein the pins have an opening that is compressed as the pins are pressed in.
