  • Patent number: 9166341
    Abstract: A mounting frame is proposed for a system for preventing mating errors between electrical connectors, which mounting frame surrounds the connector at least on the plug side, wherein at least one coding element is held in the mounting frame. The coding element can rotate about its longitudinal axis and can be fixed in various radial positions in a front holding frame, wherein the front holding frame together with a rear securing frame forms the mounting frame. The coding element only interacts with a coding element on the mating connector to be connected when two connectors are being mated in a correspondingly correct position in the mounting frame, thus allowing the connectors to be mated.
