SYSTEM FOR PREVENTING MATING ERRORS BETWEEN ELECTRICAL CONNECTORS

摘要

A system for preventing mating errors between electrical connectors (30,31) comprises a mounting frame (1,1´) surrounding a connector (30) at least on a plug side, wherein at least one coding element (20) 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 (A). The mounting frame is formed from the front holding frame and a rear securing frame (B) together. The coding element is only interacted with a coding element on a mating connector (31) to be connected while the two connectors are mated in a correspondingly correct position in the mounting frame, thus allowing the connectors to be mated.
