Electrical connector

An electrical connector containing a casing;

• a multipolar connection unit, which features a multiplicity of connecting elements from electricity-conducing material and a connection side, which is accessible from the exterior of the casing, meaning that a secondary connection unit with a multiplicity of secondary connecting elements from electricity-conducing material can be connected to the connecting elements of the multipolar connection unit from the exterior of the casing;
• wherein
• inside the casing at least one interface is located, which is designed as a slave and features bus connections for connecting of electrical wires of a bus and signal connections from at least one signal input and/or at least one signal output;
• a bus connection appliance is affixed to the casing, which features bus connection elements from electrically-conducing material which are accessible from the exterior of the casing, to connect the electric wires of the bus outside of the casing;
• the bus connection elements of the bus connection appliance are electrically connected inside the casing with the bus connections of the interface;
• and that the signal connections of the interface within the casing are electrically connected with the connecting elements of the multipolar connection unit;
• whereby the casing forms a mechanical unit together with the connection unit and the interface.
