Patent ID: 8085527

Claim:
A plug-in housing module for forming an-explosion-proof switchgear/distribution panel, the plug-in housing module having a plugged-in position, a separation position, and a fully removed position, the switchgear/distribution panel comprising a number of plug-in points, wherein when the plug-in housing module is in the plugged-in position at a corresponding plug-in point of the number of plug-in points, the plug-in housing module is brought into contact with electrical connection devices and is detachably fixed to carrier rails of a frame of the switchgear/distribution panel, the plug-in housing module comprising at least one switching device accessible from the outside for switching between a switching device locking position and a switching device release position, the at least one switching device comprising a switching shaft connected to a switching handle by a locking element that is movable between a locking element locking position and a locking element unlocking position, and when the at least one switching device is in the switching device release position, the plug-in housing module can be moved out of the plugged-in position into the separation position, wherein in the separation position, the contact with the electrical connection devices is interrupted, while maintaining a flameproof mechanical connection, and the separation position is determined in relation to the corresponding plug-in point by a mechanical locking device, wherein once the mechanical locking device has been released, the plug-in housing module can be fully removed from the corresponding plug-in point.
