DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-5 The present invention provides a technical solution for a DTU power distribution terminal with a wiring system:

[0027] Embodiment 1:

[0028] according to Figure 1 , Figure 4 and Figure 5 As shown, a DTU power distribution terminal with a wiring system includes a cabinet 1, a cabinet door 2 is hinged on the front of the cabinet 1, a base 14 is fixedly provided at the bottom of the cabinet 1, and a moisture-proof and penetration-proof medium can be added inside the base 14 to prevent moisture from entering the inside of the cabinet 1 through the base 14;

[0029] A wiring assembly is placed inside the cabinet 1, and the wiring assembly includes a wiring board 6 for classifying the lines inside the cabinet 1. The wiring board 6 is hinged on the inner wall of the cabinet 1. A plurality of wiring racks 11 are slidably connected to the wiring board 6. The wiring rack 11 is used to fix and adjust the position of the lines. A slide groove 7 is provided on one side of the front of the wiring board 6. A plurality of rubber blocks 8 are slidably connected inside the slide groove 7. The friction coefficient of the rubber blocks 8 is large. The sliding friction force when sliding inside the slide groove 7 is greater than gravity. The wiring rack 11 can be fixed at a specified position without setting a limiting structure. The sliding connection between the slide groove 7 and the rubber block 8 also facilitates the up and down adjustment of the wiring rack 11. The front sides of the plurality of rubber blocks 8 are fixedly connected with columns 9. The plurality of columns 9 are fixedly connected to one end of the corresponding wiring rack 11 by adjusting screws 10. By setting the adjusting screws 10, the connection between the wiring rack 11 and the columns 9 is changed from a movable connection to a fixed connection, which facilitates the adjustment of the wiring rack 11 in the front and rear positions.

[0030] The inner walls of the multiple sets of wiring racks 11 are all provided with strip grooves 26, which can drive the wire card board 12 to move left and right, thereby facilitating the layout of the lines and making the wiring more flexible and changeable. The interiors of the multiple sets of strip grooves 26 are all slidably connected to the multiple sets of wire card boards 12, and slots 21 are provided on both sides of the tops of the multiple sets of wire card boards 12. One side of the multiple sets of wire card boards 12 is provided with multiple wire card grooves 22, which clamp single or multiple lines together for effective distinction and classification.

[0031] A marking plate 20 is inserted and connected between two adjacent slots 21, and a label plate 23 is provided in the middle of the front of each of the marking plates 20 to annotate and register the lines on the current card board 12. A plurality of wire grooves are provided on the back of each of the marking plates 20, and a temperature-sensitive coating 25 is provided inside each of the wire grooves. When the line is connected to the card board 12, the line contacts the wire groove, thereby contacting the temperature-sensitive coating 25. When a line ages or short-circuits and causes the internal temperature to rise, the temperature-sensitive coating 25 will change color, thereby prompting the operator that the line may have safety hazards and timely troubleshooting.

[0032] The other ends of the multiple wiring racks 11 are fixedly connected to a micro box 24, and the interiors of the multiple micro boxes 24 are fixedly installed with a micro air pump 28. One ends of the multiple micro boxes 24 are fixedly connected to an end plate 29, and the middle parts of the multiple end plates 29 are provided with a rectangular groove 30. The interiors of the multiple wiring racks 11 are provided with a cavity, and the multiple rectangular grooves 30 are connected to the corresponding cavities. The inner sides of the multiple wiring racks 11 are provided with multiple air outlet holes 27 at equal intervals, and the multiple air outlet holes 27 are located below the strip grooves 26. The micro air pump 28 injects air into the cavity inside the wiring rack 11 to form an airflow, and then the airflow is discharged from the air outlet holes 27 opened on the wiring rack 11 to cool the lines to avoid the lines being too dense, which may cause local excessive temperature and damage to the lines.

[0033] In specific use, the present invention is a DTU power distribution terminal with a wiring system. When wiring, first open the cabinet door 2, then turn out the wiring board 6, install the original equipment inside the cabinet 1, and then place the line on the wiring board 6. By sliding the rubber block 8 with force, the rubber block 8 slides inside the slide groove 7, thereby driving the column 9 to slide in the slide groove 7, and then by rotating the adjusting screw 10, loosening the connection between the column 9 and the wiring rack 11, to adjust the front and rear position of the wiring rack 11. After the adjustment is completed, the adjusting screw 10 is screwed in again to fix the wiring rack 11 and the column 9. The whole process completes the adjustment of the upper and lower front and rear positions of the wiring rack 11, and then the line is clamped inside the wire clamping groove 22 on the wire clamping plate 12, and the wire clamping groove 26 is opened inside the bar groove 26. Slide the card plate 12 back and forth to make the wiring of the line not appear very compact, so as to avoid affecting the wiring because the line is not long enough. After the wiring is completed, the basic information such as the line type and time is recorded in the label plate 23 on the marking plate 20. After the registration is completed, start the micro air pump 28, and the micro air pump 28 blows the air flow from the rectangular groove 30 into the cavity inside the wiring rack 11, and then discharges it from the air outlet 27 to cool the lines on the wiring rack 11 to avoid the lines being too dense, which causes the local temperature to be too high and cause line damage. When a line is aged or short-circuited, the line contacts the temperature-sensitive coating 25, and the temperature-sensitive coating 25 will change color, thereby reminding the operator that the line may have safety hazards and should be checked in time.

The inner wall on one side of the cabinet 1 takes in air, and the inner wall on the other side discharges air, which can form a good gas circulation inside the cabinet 1 and accelerate the ventilation and heat dissipation inside the cabinet 1.

[0036] One end of multiple mounting seats 5 is snap-connected with air tubes 16, multiple fans 18 and multiple exhaust fans are installed in the corresponding air tubes 16, one end of multiple air tubes 16 is snap-connected with mounting tubes 19, one end of multiple mounting tubes 19 is snap-connected with net tubes 4, and rubber rings 17 are provided at the connection between the corresponding mounting tubes 19 and the net tube 4. The rubber ring 17 makes the connection between the net tube 4 and the mounting tube 19 more firmly and tightly connected. A dry medium, such as a desiccant, can be placed inside the net tube 4. When the fan 18 takes in air, the incoming air is dried to remove moisture in the wind, thereby avoiding affecting the drying effect inside the cabinet 1.

[0037] Multiple through slots 13 are provided on both sides of the cabinet body 1, and multiple mounting seats 5 are installed inside the corresponding through slots 13. One side of the multiple through slots 13 is movably connected with a cover plate 3 through multiple elastic sheets 15.

[0038] In specific use, the present invention is a DTU power distribution terminal with a wiring system. During assembly, multiple mounting seats 5 are installed in the through slots 13 opened on both sides of the cabinet 1, and then air ducts 16 are installed at the ends of the multiple mounting seats 5. A fan 18 is installed inside the air duct 16 on one side of the inner wall of the cabinet 1, and an exhaust fan is installed inside the air duct 16 on the other side of the inner wall of the cabinet 1. Then, the mounting tube 19 is installed at the end of the air duct 16, and then a net tube 4 is installed inside the mounting tube 19. A drying medium, such as a desiccant, can be placed inside the net tube 4 to improve the internal drying effect. Then, the cover plate 3 is installed on the through slot 13 on one side of the exhaust fan through the elastic sheet 15. At this time, the fan 18 and the exhaust fan are driven, and the fan 18 blows air into the interior of the cabinet 1. The exhaust fan extracts the internal air of the cabinet 1, taking in air while exhausting air. When exhausting air, the cover plate 3 is blown open by the wind, forming a stable airflow circulation path inside the cabinet 1, thereby ventilating and cooling the interior of the cabinet 1.
