Der Kontaktteil jedes Verbindungsstückes 24 weist einen im wesentlichen rechteckigen Streifen aus einem Leiterwerkstoff, z. B. Metall, auf, der an einem Ende mit zwei kreisförmigen und voneinander getrennten Löchern 26 versehen ist, damit er zwischen einander benachbarte Zapfen 12 und über ein Endpaar von Distanzteilen 14 paßt, welche dazu dienen, die beiden Hakenteile 22 einer Kontaktschiene 28 festzulegen. Vorzugsweise liegt das Verbindungsstück 24 unter den beiden Hakenteilen 22 und, wie in F i g. 3 dargestellt ist, weist der Streifen 24 zum Zweck einer gewissen Nachgiebigkeit zusätzlich mindestens eine Biegung auf, damit er die nach außen vorstehenden Bogenteile eines Kontaktelementes aufnehmen kann.The F i g. 2, 2a and 3 of the drawing show the arrangement of electrical connectors along the sides of a breadboard, each connector is arranged so that it is the outwardly protruding arcuate parts of a contact bar of another Can accommodate plug-in panel. The contact portion of each connector 24 has a substantially rectangular strips of a conductor material, e.g. B. metal, on which at one end with two circular and separate holes 26 is provided so that it is between adjacent pins 12 and fits over an end pair of spacer parts 14 which serve to secure the two hook parts 22 of a contact bar 28 to be determined. The connecting piece 24 is preferably under the two hook parts 22 and, as in Fig. 3 is shown, the strip 24 for the purpose of a certain flexibility additionally at least a bend so that it can accommodate the outwardly protruding arcuate parts of a contact element can.

Wie in F i g. 4 dargestellt ist, weist eine Mehrfachsteckplatte 40 zwei oder mehr Einzelplatten oder Schichten 42,43 auf, von denen jede eine Mehrzahl von darin angebrachten Stecklöchern 44 hat, welche so angeordnet sind, daß bei aufeinandergelegten Platten die Stecklöcher koaxial zueinander liegen. Jedes Steckloch wird an seinem Rand von zwei senkrecht zueinander liegenden Kontaktschienen übergriffen, welche sich seitlich erstrecken und Anschlüsse 46 bilden.As in Fig. 4 has a multiple plug-in panel 40 has two or more individual plates or layers 42, 43, each of which has a plurality of has attached holes 44 therein, which are arranged so that when the plates are placed one on top of the other Plug holes are coaxial with one another. Each plug hole is at its edge by two perpendicular to each other overlapping contact rails which extend laterally and form connections 46.
