In downhole apparatus for an oil well, components (26) are installed in tubes (28) received in a space defined between an outer case (20) and an inner length of cylindrical production column (24) that is eccentric relative to the case (20). Each tube (28) is fixed at one end to an interconnection box (30) that is also received in said space, and that has electrical conductors passing therethrough. The tubes (28) are fixed to the box (30) by welding, and the ends of the tubes remote from the box are closed by plugs that are welded on.

Dans un appareil de fond destiné à un puits de pétrole, on installe des composants (26) dans des tubes (28) contenus dans un espace situé entre une enveloppe extérieure (20) et une longueur intérieure d'une colonne de production cylindrique (24) qui est excentrique par rapport à l'enveloppe (20). Chaque tube (28) est fixé au niveau d'une extrémité sur un boîtier d'interconnexion (30) également contenu dans ledit espace et traversé par des conducteurs électriques. Les tubes (28) sont fixés sur le boîtier (30) par soudage, et les extrémités des tubes éloignées du boîtier sont fermées par des obturateurs soudés à ces extrémités.
