1. A system for preventing mating errors between electrical connectors which can be connected to one another in pairs,
comprising first and second multi-part mounting frames (1, 1′), said first mounting frame for surrounding at least a part of one connector (30), at least on the plug side, and said second mounting frame for surrounding at least a part of a mating connector (31), each of said first and second mounting frames comprising at least one coding element (20) which is arranged in the mounting frame (1, 1′) and inserted through a coding opening (2) in the mounting frame (1, 1′) in a radial position which can be rotatably varied about its longitudinal axis, wherein a coding element (20) of said first mounting frame surrounding a of a connector (30) interacts with a coding element (20) of said second mounting frame surrounding a part of a mating connector (31) to allow the connector (30) and mating connector (31) to be mated only when the coding elements are in a correspondingly correct position in the mounting frames (1, 1′), wherein each mounting frame (1) is formed from a front holding frame (A), which is first in the mating direction, and a second, rear securing frame (B), which is arranged immediately behind it, wherein the front holding frame (A) has coding openings (2) for insertion of coding elements (20), and wherein the rear securing frame (B) can be connected to the front holding frame (A) in order to secure the coding elements (20) which can be inserted into the front holding frame (A). |
