And because the limiting structures are introduced into the joints, the problems of wiring errors or poor wiring and the like are not easy to occur, and the possibility of equipment failure or damage is reduced to a great extent. In addition, this application has introduced dual sealing washer in connecting, and after the grafting is accomplished, the deformation takes place for the sealing washer extrusion to effectively avoided moisture to get into the inside possibility of connecting, promoted street lamp connecting device's waterproof performance. Moreover, the street lamp connecting device that this application provided maintains very conveniently in the later stage, and when needs change or maintenance, the mode quick replacement of accessible plug need not to carry out operations such as disconnect, wiring, envelope curve, maintains fastly, efficient, and the cost of labor is low.
