MODULARE ELEKTRISCHE VORRICHTUNG, BEI DER JEDES MODUL AUF EINER ENTSPRECHENDEN HALTERUNG BEFESTIGT WIRD, UND ELEKTRISCHES SYSTEM, DAS EINE SOLCHE ELEKTRISCHE VORRICHTUNG UMFASST

摘要

The invention provides a modular electrical device and an electrical system comprising the same. The electrical device (114) includes : a main module (116) ; an auxilary module (118) which is electrically connected to the main module (116) ; at least one attachment which attaches the auxiliary module (118) to the main module (116) so as to prevent the auxiliary module (118) from disengaging the main module (116). The attachment allows the auxiliary module (118) moves in a front-rear direction between a position proximate to and a position away from the main module (116) with respect to the main module (116).
