Disclosed is a floor-to-ceiling pillar, including a main body, an upper adjusting rod and a lower adjusting rod respectively sleeved inside both ends of the main body. The main body includes a pole body and electrified assemblies. The upper adjusting rod and the lower adjusting rod are respectively sleeved inside both ends of the pole body, to fix the floor-to-ceiling pillar through the upper adjusting rod and the lower adjusting rod. The electrified assemblies are sleeved on the pole body, and are capable of sliding along the pole body and are rotatably arranged around the pole body. The assemblies are electrically connected to power supplies to supply power to the power-consuming parts on the electrified assemblies. The present disclosure achieves the functions of storage, illuminating, charging, and power supply at different heights and orientations only in a small space.

A system is provided for supporting an electrical component in an electrical device of an electrical distribution system. The system includes at least one hook connected to a cabinet frame or structural member of the electrical device; and at least one rod attached to the electrical component. The at least one rod is slidably received in the hook such that the electrical component is held in close proximity to the cabinet frame or structural member of the electrical device while the electrical component is being attached to the cabinet frame or structural member by hardware. The electrical component can be a bus assembly of a switchboard.

A fastening device for fastening a DIN rail to a wall includes: at least one fastening element having a wall fastening portion for fastening the fastening element to the wall, and a DIN rail fastening portion for fastening the fastening element to the DIN rail. When in a fastened state, the DIN rail fastening portion is guided at least in some regions through an opening formed in the DIN rail. The DIN rail fastening portion includes a tongue and groove system into which a portion of the DIN rail is inserted in the fastened state.

This distribution assembly (100), configured to distribute electrical energy from a power source to at least one electrical load, comprises a power bus (124) which comprises a plurality of busbars (122) each having, at one end, a portion for connection to an output terminal of a main box (200). The power bus defines a connection zone, which extends along a connection plane (P124) and is provided for the connection of at least one outgoing box (300) on a front side of the connection plane (P124). The distribution assembly (100) comprises a cooling device (400), which includes a contact plate (410) for cooperation with a rear face (231) of the main housing (200), a radiator (420) which extends from a rear side of the connection plane (P124), and at least one heat pipe (430), which connects the contact plate (410) to the radiator (420).

A fastening member of an electrical connection unit includes a shaft, a base portion, and a heat storage portion. The shaft is inserted into a first attachment hole of a first member and a second attachment hole of a second member in a state in which the first attachment hole and the second attachment hole overlap each other in a first direction. The shaft has a screw thread. When a direction intersecting the first direction is a second direction, a width of the base portion in the second direction is larger than a width of the shaft. The base portion faces the first member or the second member in the first direction. The heat storage portion is provided on a side opposite to the shaft with respect to the base portion. The heat storage portion is formed integrally with the base portion.
