Disclosed is a conductive track-typed mounting assembly, comprising a guide rail (1) and at least one suspending component (2) slidably connected onto the guide rail (1), wherein the guide rail (1) is provided with a first rail (11) on which the suspending component (2) can slide; at least two electrodes (11a, 11b, 11c) are provided in the first rail (11); and each suspending component (2) comprises a trigger member (22a, 22b) for current conduction corresponding to each electrode (11a, 11c). In the conductive track-typed mounting assembly, the suspending component can not only conduct current, but can also hang a weight, and the positive and negative electrodes can be arranged and converted creatively and conveniently, so that the suspending component can move on the guide rail at any adjustable interval, so that the mounting assembly is suitable for installing advertisement lamp boxes, advertisement machines, lamps and so on in public places or in the home. It can further equip the guide rail with lighting lamps so as to be applied to illumination for industrial production places, shop windows and counters and so on. In addition, since a plurality of electrodes can be provided in an inner side of the guide rail, different types of low-voltage direct currents and low-voltage alternating currents can be supplied according to requirements.
