Definitions

  • the invention relates to an ignition bridge support for electrical detonators, in which an insulating body with at least one bore is arranged in a metallic ring, in which a contact pin is fitted as a power supply line and is electrically connected to the metal ring by an ignition bridge.
  • Ignition bridge carriers of the type mentioned which are used for igniting ignition sets, delay sets, pyrotechnic mixtures and for igniting primary substances and sets, are known from DE-A-34 16 735. This
  • Ignition bridge carriers can only be subjected to low mechanical and thermal loads.
  • the invention seeks to remedy this.
  • the contact pin is provided with a bead which defines the position of the contact pin in the bore of the insulating body.
  • two bores are arranged in the insulating body, in which contact pins are fitted as current leads, which are connected to one another in an electrically conductive manner by means of an ignition bridge.
  • the insulating bodies are preferably made of aluminum oxide ceramic with an Al 2 O 3 content> 90%.
  • the outer surface of the insulating body and the walls of its holes can be metallized.
  • the ignition bridge carrier according to the invention offers advantages in its manufacture.
  • the ignition bridge carrier according to the invention offers advantages in its manufacture.
  • FIG. 1 shows a longitudinal section through the ignition bridge support with ignition bridge and Figure 2 is a plan view of the ignition bridge support.
  • the ignition bridge carrier consists of a metallic ring 1, in which an insulating body 2 made of ceramic is arranged.
  • the insulating body 2 can be metallized on its outer surface 6 (not shown). It has two bores in which electrically conductive contact pins 3 are arranged.
  • the contact pins 3 are provided with thickenings 7 in order to fix their position in the bores.
  • Metal ring 1 and insulating body 2 or insulating body 2 and contact pins 3 are connected to each other by brazing at about 800 to 900 ° C. It has certain advantages to provide the ends of the holes with chamfers 8.
  • Solder wells 9 are formed.
  • the two solder wells and thus the contact pins 3 are electrically conductively connected via a metal layer 4 which is applied by sputtering.
  • the actual ignition bridge 5 and thus the resistance between the contact pins 3 can be worked out of the metal layer 4 by means of laser trimming technology known per se. In order to ensure closed metal layers 4, care must be taken that the surface roughness

Abstract

Un support pour ponts d'allumage de fusées d'amorçage comprend dans une bague métallique un corps isolant pourvu d'au moins un alésage dans lequel s'adapte une tige de contact qui sert d'amenée de courant. L'amenée de courant est électriquement connectée à la bague métallique par un pont d'allumage. La tige de contact (3) est pourvue d'un renflement (7) qui détermine sa position (3) dans l'alésage du corps isolant.
