An electrical power distribution housing (100) has an elongate opening (104) intended to allow the adapters/plugs (1400) to be inserted to receive electrical power at any point along the housing. A springleaf assembly (300) is mounted adjacent to the elongate opening (104) and extend to close the elongate opening (104) during a non-use situation. A safety grounding plate (200) is mounted on top of the springleaf assembly (300). Power conductors comprising multiple clips (402) are mounted conductor compartments (102) within the housing (100). When an adapter/plug (1400) is inserted into the housing (100) through the elongate opening (104), limbs (1001) will force the corresponding springleaf (301) to open by flexing it onto a springleaf profile (101). The adapter/plug (1400) rotates to "closed" position to slide a contact (807) into engagement with a corresponding contact (402) of the power conductor. When the adapter/plug (1400) rotates to an "open" position and is removed from the elongate opening (104), the corresponding springleaf (301) will return and to close the elongate opening (104).

A module connector (102) for uninterrupted communication is described. The module connector (102) comprises a slot (602) for receiving connector pins (702) of an I/O module 500. The slot (602) has at least one pair of mating pins (606) to connect with the connector pins (702) of the I/O module (500). The at least one pair of mating pins (606) is normally closed in absence of the connector pins (702) in the slot (602). Further, the at least one pair of mating pins (606) in a normally closed state moves to an open state upon receiving the connector pins (702) of the I/O module (500) in the slot (602).

Module connector for uninterrupted communication

An electrical series terminal with a terminal housing, with two conductor connecting elements located in it, and with two current busses, first end regions of which are each assigned to a conductor connecting element and second end regions of which together form an elastic contact region for accommodating the contact plug of a test plug. In the electrical series terminal, when the test plug is inserted into the test opening, elastic contact legs of the second end regions are bent back relative to one another and which together form a second elastic contact region for holding the contact plug of a test plug. The second contact region in the insertion direction is located in front of the first contact region so that an inserted contact plug first makes contact with the second contact region and only upon further insertion with the first contact region.

An electrical terminal block, especially for locking onto a mounting rail, has a plurality of adjacent base terminals and connectors. Each base terminal has a terminal housing, with at least one conductor terminal element and at least one receptacle electrically connected to the conductor terminal element or at least two interconnected receptacles. The individual connectors have a connector housing, with at least one conductor terminal element and a plug-in contact electrically connected to the conductor terminal element. The individual connectors can be plugged onto the individual terminal housings. Reliable mechanical fixing of the connectors on the base terminals is ensured since each outer side of the base terminals has a fixing device on the terminal housing. Sides of adjacent connectors have a fixing cover with a fixing mechanism corresponding to the fixing device, so that the connectors can be mechanically connected to the fixing base terminals via the fixing covers.
