Definitions

  • the device comprises a planar body 21 formed of berylium copper, or similar material as a stamping.
  • the body 21 is bounded by an upper surface 22, a lower surface 23, side edges 24 and 25, and end edges 26 and 27.
  • the edges 26 and 27 are bent upwardly to form generally arcuately shaped terminals 28 and 29 which partially wrap around the contacts.
  • Insulative sleeves 30 and 31 are most conveniently formed by cutting lengths of fusible insulative tubing of Milar or the like.

Abstract

Dispositif de tubes à gaz à sécurité intégrée pour des tubes à gaz à trois éléments allongés ayant une électrode centrale et une paire d'électrodes d'extrémité. Le dispositif comporte un corps plan allongé (21) ayant des bords recourbés (26-27) qui forment des gaines d'isolation de bornes de contact électriques d'extrémité (30-31) formant des éléments fusibles. Des pattes centralement disposées (33-34) s'accrochent élastiquement à une broche qui est portée par l'électrode centrale du tube à gaz. Dans un deuxième mode de réalisation, une paire de plaques de court-circuit (50-51) recouvrent un élément isolateur à entrefer (60) présentant des rangées de petits orifices (66) qui forment des entrefers à travers lesquels les surtensions peuvent former des arcs électriques afin d'assurer une fonction de support équivalente à celle du tube à gaz.
