Definitions

  • the invention relates to a contact pin with ceramic insulation, which is provided at one end with a tab for receiving a pole piece and has a jump at the other end, which is supported on a corresponding jump of the flat channel leading through the ceramic insulation.
  • Contact pins of the type mentioned are known. They serve as a power supply for electric lamps, especially for halogen lamps.
  • GB-A-2,093,632 teaches a lower part of a lamp in which a contact pin is guided through a ceramic insulation with a slot-shaped recess and protrudes from the ceramic insulation with a contact tab.
  • a disadvantage of the known contact pins is that the connection of the current-carrying conductor to the ceramic insulation is not wobble-free, which leads to vibrations of the incandescent filament and thus negatively influences its service life.
  • the metal-insulation connection is wobble-free, but at higher temperatures to which the contact pins are exposed, volatile substances gas out, which are deposited on the reflector of the lamp. The insulation loses its shape at correspondingly high temperatures.
  • the invention seeks to remedy this.
  • the invention solves the problem in that the first jump is followed by a second jump which has an undercut in front of the contact tab and which protrudes slightly from the channel and is provided with a compression.
  • the second jump has an undercut.
  • the contact pin 1 made of electrically conductive material such as steel, copper, tungsten and the like is provided with a ceramic insulation 2.
  • the ceramic insulation 2 has a flat channel 3, which is provided with a crack 4.
  • the contact pin 1 is provided with a tab 5 for receiving a pole piece and with at least one jump 6, with which it is supported on the jump 4 of the flat channel 3.
  • the contact pin has a further crack 7 which protrudes slightly (1-3 mm) from the flat channel 3.
  • This step 7 is provided with a compression 8, whereby the contact pin 1 is positively and wobble-free connected to the ceramic insulation 2 in cooperation with step 6.
  • the step 7 is provided with an undercut 9. Hot upsetting has proven to be particularly advantageous.
  • the contact pin is brought to the thermoforming temperature by electrical means.
