While the current-conducting profiles 120, 220 have channels with continuous channel walls 1273, 2273 over the major part of their respective longitudinal extension, which is not shown in Figure 15, they form alternatingly arranged projections 1274, 2274 and recesses 1271, 2271 in their plug-in sections.
  • a recess 1271, 2271 of each plug-in section is formed between two projections 1274, 2274 of the respective plug-in section.
  • the recesses 1271, 2271 are designed in such a way that they are suitable for receiving a respective projection 1274, 2274 of the other plug-in section.
  • FIGS. 15a and 15b the current-conducting profiles 120, 220 are shown with their plug-in sections plugged into one another.
  • FIG. 15a shows the current-conducting profiles 120, 220 and thus the current-conducting rail accommodated in a mounting rail 1.
  • Figure 15c shows the plug-in section of a first of the current-conducting profiles 120
  • Figure 15d shows the corresponding plug-in section of a second of the current-conducting profiles 220, these plug-in sections corresponding to one another being arranged plugged into one another in order to implement a current-conducting rail according to the invention, as is shown in Figures 15a and 15b .
  • the projections of both plug-in sections each have insertion bevels 1272, 2272 on their longitudinal ends, with which they form the longitudinal ends of the respective plug-in section.
  • the projections each form a section of a channel of the current conducting rail.
  • This defined longitudinal region 1275, 2275 is at a distance from the respective longitudinal end of the plug-in section, which forms the respective longitudinal end of the respective current-conducting profile 120, 220.
  • this defined longitudinal area is at a distance from the longitudinal ends of the respective projection 1274, 2274 and thus also from the longitudinal ends of the recess 1271, 2271 of the plug-in section formed between two adjacent projections 1274, 2274 of one of the plug-in sections.
  • this ensures that the current-conducting profiles 120, 220 can be simply plugged into one another in the longitudinal direction, since the respective recess 1271, 2271, which has the associated projection 1274, 2274 of the another plug-in section, has a sufficiently large clear width at its longitudinal end in order to accommodate this projection 1274, 2274 with as little friction as possible.

Abstract

L'invention concerne un système pour mettre en oeuvre une lampe allongée, le luminaire et un procédé pour produire le système (100) dans sa position de fonctionnement. Ce système comprend au moins un rail porteur (1), un rail conducteur de courant (2) et plusieurs fils conducteurs (4) disposés dans des canaux (21) du rail conducteur de courant (2). Le rail conducteur de courant (2) est disposé dans la position de fonctionnement à l'intérieur (10) et est fixé au rail de support (1), le système (100) comportant en outre une partie de fixation (3) qui est maintenue en place dans la position de fonctionnement entre le rail conducteur de courant (2) et le rail de support (1) dans une zone centrale (20) de l'extension longitudinale du rail conducteur de courant (2) sur une partie de fixation du rail de support (1) et sur une partie de fixation du rail conducteur de courant (2) afin d'éviter un déplacement relatif du rail de support (1) et du rail conducteur de courant l'un par rapport à l'autre.
