A device for interconnecting electrical circuits fixed to a body member 4 such as a bus and a door 2 movably mounted to close an aperture in the body member, comprises housing means 12, 14 and at least one length of flat conductor cable 16 accommodated within the housing means 12, 14 and provided with electrical end connections and one or more ribbon-like conducting elements. The cable flexes in order to accommodate movement eg. rotational and translational between the body member 4 and door 2 and includes a bight 16a and a spiral. The cable is guided from a channel 14 across a pivot housing 12 and spirally around a pivot bush 30 and bushing 26, to pass through a bushing slot 24 and then between a door plate 28 and pivot plate 32 and into the door 2. Housing 12 is guided by the channel 14 and a roller 36 in a body slot 38, the pivot bush 30 being adjustable along a slot 21 to take up wear or misalignment. A hollow, deformable edge strip on the door 2 encloses a light source and detector, deformation of the strip eg. on blockage of the door, interfering with light transmissal along the strip. <IMAGE> |
