Background technology
Low-voltage cable junction box has advantages of that volume is little, be convenient to installation and maintenance, use safe, so be widely used on low-voltage circuit.The low-voltage cable junction box using at present, comprises casing, chamber door and case lock, in casing, by insulating support, is fixed with four groups of horizontal, stepped is arranged bus bar copper rows, during installation, bottom half is installed on the ground.The deficiency of this low-voltage cable junction box is: due in Rural Power Grid Construction transformation, entrance line adopts low-voltage cable more, an entrance line cable can only be received a collection family case, most house, rural area is misaligned now, street is crooked, adopt console mode installing cables feeder pillar, certainly will hinder the current of people and vehicle, and also dangerous; In addition, because bus bar copper row is horizontal, stepped arrangement, during wiring, easily collide, cause dangerous.Known by retrieving, although have multiplely about the improved report of low-voltage cable junction box, yet there are no and be exclusively used in rural power grids, low-voltage cable junction box is hung to report on the wall.
Summary of the invention
The purpose of this utility model be to provide a kind of not only simple in structure, production cost is low, installation is easy, use safety, and be applicable to Rural Power Grid Construction transformation, make lower family cable separate 2-3 branch cable by feeder pillar, be connected in the case of collection family or receive subscriber equipment, not taking up an area again face, do not hinder the wall-hanging low-voltage cable junction box that the road is clear.
In order to reach above object, the technical scheme that the utility model adopts is: this wall-hanging low-voltage cable junction box, comprise casing and corresponding chamber door and case lock thereof, chamber door is connected with the opening's edge of casing by hinge pin, it is characterized in that: left and right four bights of described casing rear wall are equipped with horizontal mounting panel, at the middle part of four horizontal mounting panels, are equipped with the expansion bolt fixing with wall; Rear wall top in casing is provided with lateral isolation support, rear wall middle part in casing is provided with protruding lateral isolation pole, the upper end of four groups of longitudinal step-like bus bar copper rows is all fixed on lateral isolation support, it is upper that the lower end of four groups of longitudinal step-like bus bar copper rows is all fixed on protruding lateral isolation pole, and four groups of longitudinal step-like bus bar copper rows equidistant, be parallel to each other; Diapire at casing is provided with three wire holes and an entrance hole; The top of described casing is front oblique flashing board.
The utility model is also implemented by following measure: the middle and lower part, two side of described casing is provided with louver-type ventilation window.
The shoulder height of described longitudinal step-like bus bar copper row is 50mm, and the distance between adjacent longitudinal step-like bus bar copper row is 50-100mm.
The beneficial effects of the utility model are: this wall-hanging low-voltage cable junction box, not only simple in structure, production cost is low, installation is easy, use safety, and be applicable to Rural Power Grid Construction transformation, make lower family cable separate 2-3 branch cable by feeder pillar, be connected in the case of collection family or receive subscriber equipment, do not take up an area again face, do not hinder that the road is clear, and be conducive to aeration-cooling; Meanwhile, step-like owing to bus bar copper row being changed into longitudinally and curving, so easily collide in the time of can avoiding wiring, make wiring operation safe.
