  • Terminal housing for connection devices for conductive contacts on a photovoltaic panel or panel are known per se, so from DE 20 2007 012 096. Thereafter, the terminal device used in the terminal housing has first connection contacts for connecting the conductive contacts of the photovoltaic panel and second terminals for connecting external conductors and at least one or more connected to the terminal diodes.
  • Electricity generating photovoltaic systems generally have at least one photovoltaic panel for generating electricity from sunlight.
  • flexible, easily flexible flat conductor are usually led out of the photovoltaic panels, which make it possible to connect the photovoltaic panels - usually via a multi-conductor cable - for example, to a domestic installation or initially to electrical equipment such as an inverter or the like.
  • the individual flexible flat conductor by means of individual terminals or the like. By hand contacted, which is relatively expensive. Then, a connection housing is set via the contacted flat conductor, which usually contains a certain number of diodes.

  • At least one screw 5, which penetrates the cover section 4 and which can be screwed into the base section 3, serves for this purpose.
  • the screw 5 has a head 6 and a shaft 7.
  • the screw 5 passes through a passage opening 8 of the lid section 4.

If necessary, the screw can also serve as a seal to possibly indicate the warranty status of the housing. It is also a simple, safe and cost-effective solution for servicing the case to open or close the case almost powerless.
  • the selected arrangement makes it possible to unscrew or release the cover section 4 onto the base section 3 with a sufficient assembly tension force without an appreciable force being introduced axially into the photovoltaic panel via the base housing (see FIG. 2). In this way, the risk of damage to the photovoltaic panel is reduced significantly in a simple manner compared with known constructions.
