Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a separated distribution box with hierarchical wiring of high and low voltage devices. Background Art

[0002] At present, the market has increasingly higher requirements for the miniaturization, integration, three-proofness and maintainability of distribution boxes.

If the mounting panel of the device mounting plate is too large, it will be inconvenient for its installation and maintenance. If the mounting panel of the device mounting plate is too small, the operability and testability of the device will be reduced; and installing high and low voltage devices on the same mounting plate will cause cross wiring, which is not in line with electrical principles.

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] Example 1

[0046] like Figure 1-Figure 2 As shown, this embodiment proposes a partitioned distribution box with hierarchical wiring of high and low voltage devices, including a distribution box body 10, the distribution box body 10 includes a distribution box bottom plate, a distribution box side plate and a distribution box cover plate 17, and a distribution box panel 12 and a distribution box outlet plate 14 serve as two distribution box side plates of the distribution box body 10. The distribution box bottom plate, the distribution box side plate and the distribution box cover plate 17 together form a distribution box cabin 11, and the distribution box cabin 11 is used to install electrical devices.

[0047] A concave slide groove 18 is provided inside the distribution box body 10. The concave slide groove 18 is opened on the side panel of the distribution box. The concave slide groove 18 is arranged on two opposite side panels of the distribution box. A first layer of partition plate 21 is installed in the concave slide groove 18. The first layer of partition plate 21 is slidably installed in the concave slide groove 18.

[0048] The concave slide groove 18 has a limiting device at one end close to the distribution box outlet plate 14, and the limiting device is used to limit the sliding extreme position of the first layer partition plate 21. The concave slide groove 18 and the first layer partition plate 21 have openings at one end close to the distribution box panel 12, and are connected and fixed by screws. Only two mounting screws are used to fix the first layer partition plate 21, making the installation and maintenance of the partition plate in a small space more operable.

[0049] A wire clip is installed on the concave slide groove 18 to standardize the wiring.

[0050] The first partition plate 21 is substantially the same size as the bottom plate of the distribution box. The first partition plate 21 divides the distribution box body 10 into two spaces, the lower space being used to install the heating device 19 and the upper space being used to install the high-voltage device 32 and the low-voltage device 22 .

[0051] The side plate of the distribution box is provided with heat dissipation holes in the lower space for heat dissipation of the heating device 19. The heat dissipation holes are arranged according to the requirements of the air duct. Figure 3 and Figure 4 As shown, the lower half of the distribution box panel 12 is provided with a distribution box panel heat dissipation hole 13 for heat dissipation of the heating device 19, but not in the upper half; the lower half of the distribution box outlet plate 14 is provided with a distribution box outlet plate heat dissipation hole 15 for heat dissipation of the heating device 19, but not in the upper half. The upper half of the distribution box outlet plate 14 is provided with a distribution box connector installation hole 16.

[0052] like Figure 5 As shown, a heating device wiring hole 27 is respectively provided at the front and rear diagonals of the first layer partition plate 21 according to actual wiring conditions, for wiring the heating device 19 in the lower layer space.

[0053] like Figure 6 As shown, a plurality of welding studs 25 are welded on the top surface of the first layer of partition plate 21, each of which is connected to an insulating column 24, and all of the insulating columns 24 are used to support the second layer of partition plate 31, and the second layer of partition plate 31 is detachably connected to the insulating column 24 by screws, as shown in FIG. Figure 7 As shown, a second layer partition plate mounting hole 34 is opened on the second layer partition plate 31 , and screws are installed in the second layer partition plate mounting hole 34 to fix the second layer partition plate 31 to the top end of the insulating pad column 24 .

[0054] The bottom surface of the first layer of partition plate 21 is welded with a first layer of partition plate welding nut 26 according to actual needs, and a hole is reserved on the first layer of partition plate 21 at the welding position of the first layer of partition plate welding nut 26, and the low-voltage device 22 and other devices 23 are installed on the first layer of partition plate 21. During installation, the low-voltage device 22 and the other devices 23 are detachably installed on the first layer of partition plate 21 by screws, and the screws can be directly screwed into the first layer of partition plate welding nut 26.

[0055] like Figure 7 As shown, a second layer partition plate welding nut 33 is welded on the bottom surface of the second layer partition plate 31 according to actual needs, and a high-voltage device 32 is installed on the second layer partition plate 31. The high-voltage device 32 is detachably installed on the second layer partition plate 31 by screws, and the screws are directly screwed into the second layer partition plate welding nut 33.

[0056] The height of the insulating column 24 is adjusted according to the actual height of the low-voltage device 22, leaving enough space as much as possible for testing the low-voltage device 22 and other devices 23, thereby improving the testability of the distribution box.

[0057] The distribution box body 10 is provided with a first layer component 20 and a second layer component 30. The first layer component 20 includes a first layer partition plate 21 and low-voltage devices 22 and other devices 23 thereon. The second layer component 30 includes a second layer partition plate 31 and high-voltage devices 32 thereon.

[0058] Further, such as Figure 6 and Figure 8 As shown, both ends of the first layer partition plate 21 and the second layer partition plate 31 are bent to improve their strength.

[0059] After the first layer of partition plate 21 of the utility model slides into the concave chute 18, the distribution box is divided into two layers, the lower layer is used to install the heating device 19, the first layer of partition plate 21 is used to install the low-voltage device 22, the second layer of partition plate 31 is installed on the first layer of partition plate 21 through the insulating pad column 24, and the second layer of partition plate 31 is used to install the high-voltage device 32. The structural design of the utility model is scientific and reasonable. After the heating device 19 is separated separately by the first layer of partition plate 21, the upper layer of the distribution box no longer needs to open a heat dissipation hole, and the three-proof performance of the distribution box body is better; the first layer of partition plate 21 is connected by sliding through the concave chute 18 and the first layer of partition plate 21 is welded with welding studs 25, which can greatly reduce the number of screws inside the distribution box body, and facilitate installation and maintenance; the two layers of partition plates can install and route the high and low voltage devices in layers to avoid the crossing of high and low voltage harnesses, which can effectively solve the problems of the existing distribution box heating devices not being separated separately, the limited space in the box body, the partition plate and the inconvenient installation and maintenance of the screws, and the crossing of high and low voltage devices.

[0060] Example 2

[0061] The difference between this embodiment and embodiment 1 is that:

[0062] After the distribution box cabin 11 is welded and formed, the concave chute 18 is welded on both sides of the inner wall of the distribution box cabin 11, and the distribution box panel 12, the distribution box outlet plate 14 and the distribution box cover plate 17 are connected to the distribution box cabin 11 by screws, which is convenient for disassembly and maintenance. After the internal components of the distribution box cabin 11 are installed, the distribution box panel 12, the distribution box outlet plate 14 and the distribution box cover plate 17 are installed with screws.

[0063] Specifically, the heating device 19 is first installed on the bottom plate of the distribution box at the bottom of the distribution box cabin 11. After the heating device 19 is wired, the cable is passed through the heating device wiring hole 27 of the first layer partition plate 21. Then the first layer partition plate 21 is installed through the concave grooves 18 on both sides, and the first layer partition plate 21 and the concave grooves 18 are fixed by installing screws in the first layer partition plate installation holes 28 on the first layer partition plate 21. At this time, the first layer partition plate 21 divides the distribution box body 10 into two layers, upper and lower. Since the heating device 19 is installed on the lower layer, the heat of the heating device 19 cannot be transferred to the upper layer, and the upper layer does not need to open a heat dissipation hole, and the three-proof performance of the distribution box body 10 is greatly improved. Then, the insulating pad column 24 is installed through the welding stud 25 welded on the front (top surface) of the first layer partition plate 21, and the low-voltage device 22 and other devices 23 are installed through the first layer partition plate welding nut 26 welded on the back (bottom surface) of the first layer partition plate 21. During installation, the insulating column 24 is as close to the end of the distribution box panel 12 as possible, leaving as much operating space as possible for the installation of the distribution box body outlet connector, further improving the operability of the entire box. Then, the second layer partition plate 31 is connected to the insulating column 24 by installing screws in the second layer partition plate installation hole 34 on the second layer partition plate 31, and the second layer partition plate welding nut 33 is welded on the back (bottom) of the second layer partition plate 31 to install the high-voltage device 32.

[0064] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
