Abstract
A device, used in particular in telecommunications technology to supply power to parallel-connected, electrical loads has side-by-side arranged potential lines. These are secured inside a connecting housing, with connections for supplying the operating potential. The connections supply plug-in modules for connecting individual loads, which modules are fitted against the connecting housing in longitudinal direction of the potential lines. The potential lines are configured as rigid, parallel bus bars that project on a side from the connecting housing. With the aid of passages that make contact with the bus bars, the plug-in modules are fitted side-by-side onto the bus bars, such that they fit against the connecting housing or against each other, and are frictionally secured.
Claims21
A device for supplying power to parallel connected, protective switches by means of side-by-side arranged potential lines, said device comprising:
- a connecting housing in which connections for supplying an operating potential are housed;
- at least two rigid, parallel bus bars which project from a side wall of said connecting housing, said bus bars being the potential lines;
- and
- plug-in modules for electrically connecting individual protective switches to said connecting housing, said plug-in modules having a module housing with passages therein, said passages receiving said bus bars and extending through each said module housing so that at least two plug-in modules can be arranged in a row from the connecting housing, said plug-in modules making electrical contact with said bus bars and one of the at least two plug-in modules being fitted against said connecting housing and the second of the at least two plug-in modules being fitted against said one plug-in module, said plug-in modules being frictionally secured on said bus bars.
