    • The invention comprises an electrical distribution system in which the electrical conductors are enclosed within a length of hollow conduit which is formed with a continuous slot in one wall through which a plug can be inserted and rotated to bring its contact pins into contact with the conductors. Gate means located within the conduit have a normally closed position in which the conductors are closed off from that part of the conduit containing the slot, and these are movable into the open position by entry of the plug through the slot. By closing off the conductors from the remainder of the conduit, accidental contact with the conductors is prevented even though access to the interior of the conduit may be achieved via the slot. In one embodiment of the invention, a keyway is provided in the conduit and the plug is formed with a corresponding projection which engages the keyway when the plug is fitted into the slot. The gate means is arranged such that it can only be opened by an element passing through the keyway, thus providing an additional safety feature.
    • 本发明包括一种配电系统,其中电导体封闭在中空导管的一段长度内,该中空导管的长度在一个壁上形成有一个连续的槽,一个插头可以插入并旋转,使其接触销与导体接触。 位于管道内的门装置具有常闭位置,在该常闭闭位置,导体与包含狭槽的管道的那部分封闭,并且这些位置可通过塞子进入狭槽而进入打开位置。 通过从导管的其余部分封闭导体,即使通过插槽可以实现对导管内部的访问,也意外接触导体。 在本发明的一个实施例中,在导管中设置有键槽,并且插头形成有当插头装配到槽中时与键槽接合的相应突起。 门装置被布置成使得其只能通过穿过键槽的元件打开​​,从而提供附加的安全特征。

    • The invention provides an electrical distribution system comprising a length of conduit 10 containing a plurality of continuous conductors. Electrical access to the conductors is achieved via a contact plug and a series of spaced entry apertures which are shaped to receive the plug in a particular orientation. Safety door means are provided within the conduit for each aperture and are designed to prevent contact with the conductors by means other than the correct contact plug. In one embodiment of the invention, the conduit is in two parts comprising a support section for securing to a supporting surface, and a wall section containing the entry apertures. The wall section can be connected to the support section at any desired location along its length.
    • 本发明提供一种配电系统,其包括一段包含多个连续导体的导管10的长度。 通过接触塞和一系列间隔开的入口孔实现对导体的电接触,该入口孔被成形为以特定取向接收塞子。 安全门装置设置在每个孔的管道内,并被设计成防止除了正确的接触塞以外的方式与导体接触。 在本发明的一个实施例中,导管分成两部分,包括用于固定到支撑表面的支撑部分和包含入口孔的壁部分。 壁部分可以沿其长度在任何所需位置连接到支撑部分。
