System for connecting electric conductors with potentials which differ from one another and plug-in adapter for the system

A system for connection of electrical conductors with potentials which differ from one another, comprising:

• at least two electrical terminals which are located next to one another with plug-in receptacles and
• at least two plug-in jumpers, each of which has at least two plug-in contacts which are connected to one another via a head web and are insertable into the plug-in receptacles,
• wherein the plug-in jumpers and the electrical terminals are matched to one another such that one of the at least two plug-in jumpers is insertable into any of the plug-in receptacles of a first of the at least two electrical terminals and another of the at least two plug-in jumpers is insertable into any of the plug-in receptacles of a second of the at least two electrical terminals, the first and second of the at least two electrical terminals being located directly or indirectly next to one another in a direction crosswise to a lengthwise direction of the at least two electrical terminals,
• wherein the plug-in jumpers and the electrical terminals are made matched to one another such that a distance of individual plug-in receptacles of the electrical terminals relative to one another and relative to a housing of the electrical terminals is essentially matched to a distance between individual plug-in receptacles of the second of the electrical terminals,
• wherein the plug-in jumpers are insertable into one of the electrical terminals in said lengthwise direction and are also insertable into at least two of the electrical terminals in the direction crosswise to said lengthwise direction, the lengthwise direction is substantially perpendicular to the crosswise direction and
• wherein the plug-in jumpers are detachable parts of a continuous plug-in jumper.
