  • a Blechstrei ⁇ fen a certain rigidity. This requires that the metal strip end is more or less at a predetermined location in the interior of the lamp housing. With a suitable choice of this location, the sheet metal strip must not be bent or at least not strong when a lamp is to be connected. The lamp fitter therefore, it does not have to worry about positioning the metal strip.
  • the sheet metal strip may have a deviating from a straight line shape, so have at least one bending or bending point, by which it is preformed, in the current direction.

Abstract

Dans des appareils de projection vidéo, les boîtiers de lampe recevant la lampe sont amovibles. La lampe doit être raccordée dans le boîtier. Selon l'invention, des barrettes de connexion (26, 26'; 38, 38'; 44, 44') sont intégrées dans le boîtier de lampe en tant que conducteurs de courant. Ces barrettes de connexion rigides pénètrent à l'intérieur (14) du boîtier de lampe (12, 12'), facilitant ainsi le raccordement de la lampe (16). La résistance des barrettes de connexion peut être accrue par le façonnage de profilés moulés par pression.
