Abstract: A coupling system for coupling switchgear modules comprises cover-guards wherein the cover-guards of two adjacent modules to be coupled to each other face each other. The cover-guards have enlarged portions which are received in the holes of two modules and are sealed to the modules by O-rings. Each cover-guard has at a base thereof a hole in which a contactor member having a tab is fixed and sealed such that two tabs in two adjacent modules lie in coaxial opposition. The system further includes an insulating mount which is simultaneously plugged into both cover-guards and provided in its hollow interior with a metal tubing member in which are housed a number of conductive elements that tend to grip the conductive tabs by action of circular springs or coils.
