<p>An extension cord of flat cable, particularly for undercarpet use, comprising a strip of insulated conductors located in a stiffly flexible sleeve-form shield strip mounted at opposite ends in rigid outlet supporting housings with the conductors terminated to leads of the outlets. At one end of the cable, both the shield strip and the conductor strip are fixed to the housing preventing relative longitudinal movement, whilst, at the other end, only one of the strips is fixed to the housing, the other strip being free to move relatively longitudinally during a change in the extension cord from reeled to flat condition, thereby avoiding straining the terminations or buckling the cable. In one example, the shield strip is fixed to the housing and the individual conductors of the conductor strip are connected to leads of the associated outlet by flexible metal bands bowed perpendicularly to the plane of the strip.</p> |
