The following defect of existing low-voltage cable junction box ubiquity, the first, generally only offer a cabinet door, turnover cable, all from this traveling, connects up loaded down with trivial details, be easy to make mistakes, and security performance is poor.The second, the mode of installing cabinet door before the moon is generally that hinge-type or plug-in type are hinged, can do 180 degree of rotations when cabinet door is opened.If adopt many cabinets door, the problem which certainly will cause door leaf to collide with each other.3rd, existing cable branch box does not have special ventilation equipment, and in case, hot-air cannot unimpededly be discharged, and the problem that space temperature certainly will be caused to raise affects its security performance.
The patent application document of China's application number 200320107028.2 discloses, a kind of low-voltage cable junction box, comprise casing and the cabinet door on casing that is connected through the hinge, in the front of casing, side and be separately installed with three cabinet doors, i.e. Qianmens below, side door and back door, although the cable branch box design of this structure is more reasonable, more convenient operation, security performance is better, but radiating effect is not obvious, and the temperature in cabinet can not be shown.In sum, for the defect of prior art, need good heat dissipation effect especially, the low-voltage cable junction box of temperature in cabinet can be shown, thus solve above-mentioned problem.
Utility model content
The technical problem that the utility model solves is to provide a kind of low-voltage cable junction box, to solve the problem proposed in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: a kind of low-voltage cable junction box, comprise: casing and chamber door, chamber door fixes on casing by hinges fixing, the upper end of described casing is provided with ventilation hole, the upper end of ventilation hole is provided with ventilating fan, ventilating fan is fixed on casing by support, temperature sensor is provided with in casing, chamber door is provided with thermometer, the output of temperature sensor is connected with thermometer, be provided with base plate in described casing, base plate is fixed on casing by fixed screw, and casing and back plate connections are provided with insulation cushion.
Described chamber door is provided with return air hole, and the top of described casing is provided with the suspension hook for lifting by crane.
Described base plate is provided with three-phase bus bar, closes the insulating cover of busbar, and each insulating cover is provided with the spliced eye of a plurality of output module, and spliced eye is vertically arranged on insulating cover and spliced eye on same longitude is one group, and quantity of each group spliced eye is identical; Base plate is provided with the screw preformed hole of a plurality of fixing output module.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, design ingenious, good heat dissipation effect, and can direct displays temperature on chamber door, insulating cover is provided with the spliced eye of a plurality of output module in addition, and base plate is provided with the screw preformed hole of a plurality of fixing output module, according to actual needs, the number of installing output module can be determined.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is base arrangement schematic diagram of the present utility model.
In figure: 1, casing; 2, chamber door; 3, ventilating fan; 4, thermometer; 5, return air hole; 6, suspension hook; 7, support; 8, base plate; 82, busbar; 83, spliced eye; 84, screw preformed hole; 85, output module; 86, insulating cover.
Embodiment
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1, a kind of low-voltage cable junction box, comprise: casing 1 and chamber door 2, chamber door 2 fixes on casing 1 by hinges fixing, and the upper end of described casing 1 is provided with ventilation hole, and the upper end of ventilation hole is provided with ventilating fan 3, ventilating fan 3 is fixed on casing 1 by support 7, be provided with temperature sensor in casing 1, chamber door 2 is provided with thermometer 4, and the output of temperature sensor is connected with thermometer 4.Described chamber door 2 is provided with return air hole 5.The top of described casing 2 is provided with the suspension hook 6 for lifting by crane, and be provided with base plate 8 in described casing 1, base plate 8 is fixed on casing 1 by fixed screw, and casing 1 and base plate 8 junction are provided with insulation cushion.
As shown in Figure 2, described base plate 8 is provided with three-phase bus bar 82, closes the insulating cover 86 of busbar 82, each insulating cover 86 is provided with the spliced eye 83 of a plurality of output module, spliced eye 83 is vertically arranged on insulating cover 86 and spliced eye 83 on same longitude is one group, and quantity of each group spliced eye 83 is identical; Base plate 8 is provided with the screw preformed hole 84 of a plurality of fixing output module 85.
Feeler in the utility model on output module 85 inserts the spliced eye 83 of insulating cover 86, the now busbar clamping of feeler and insulating cover 86 inside, ensures that output module 85 and busbar UNICOM conduct electricity.Utilize screw by output module 85 fixation simultaneously; Screw is connected with the screw preformed hole 84 on base plate 8 through output module 85.When installing output module 85 by said structure, do not need to use a lot of erecting tools, it is simple, convenient to install.According to actual needs, the number of installing output module 85 can also be determined additionally by said structure; Spliced eye 83 is vertically arranged on insulating cover 86 and spliced eye 83 on same longitude is one group, quantity of each group spliced eye 83 is identical, can guarantee that each output module 85 firmly can be fixed on insulating cover 86 and to contact conduction fully with busbar 82.
