Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage electrical appliances, in particular to a distribution box and a distribution system. Background Art

[0002] With the development of electric power technology, distribution boxes are used more and more widely. Distribution boxes can reasonably distribute electric energy, facilitate the opening and closing operations of circuits, have a high level of safety protection, can intuitively display the conduction status of circuits, are easy to manage, and are conducive to maintenance when circuit failures occur.

[0003] In order to improve the integration of the circuit, the distribution box is usually equipped with distribution equipment containing weak current components and strong current components. However, the existing distribution box has unreasonable allocation of strong current area and weak current area, which makes the operation of strong current control line and weak current control line complicated. The strong current control line and weak current control line are easily intertwined, which causes the component signals of the strong current area and the weak current area to interfere with each other, seriously affecting the accuracy of control signal transmission. In addition, the wiring of the strong current area and the weak current area can only enter and exit in the same direction, which cannot meet the wiring requirements of different working conditions.

[0016] The beneficial effects of the utility model include:

[0017] The distribution box provided in the present application includes a box body and a partition; the box body has a accommodating cavity, and a high-voltage wiring area and a low-voltage wiring area are arranged in the accommodating cavity.

The present application divides the accommodating cavity of the box into a high-voltage wiring area and a low-voltage wiring area, and sets a partition between the high-voltage wiring area and the low-voltage wiring area, so that the high-voltage wiring area and the low-voltage wiring area can be isolated from each other. In this way, the high-voltage control line arranged in the high-voltage wiring area and the low-voltage control line arranged in the low-voltage wiring area can be set independently, and the high-voltage control line and the low-voltage control line will not be intertwined with each other, which can solve the problems of complex wiring and messy routing of the high-voltage control line and the low-voltage control line in the distribution box in the prior art; and because the high-voltage wiring area and the low-voltage wiring area are arranged in staggered layers, the high-voltage control line and the low-voltage control line can also be connected in any direction to meet the routing requirements of different working conditions.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Please refer to Figures 1 to 5 The present embodiment provides a distribution box, which includes a box body 10 and a partition 20; the box body 10 has a receiving chamber 11, and a strong current wiring area 12 and a weak current wiring area 13 are arranged in the receiving chamber 11. The partition 20 is arranged between the strong current wiring area 12 and the weak current wiring area 13, and is used to separate the strong current wiring area 12 and the weak current wiring area 13. The strong current wiring area 12 and the weak current wiring area 13 are arranged in a staggered manner in a first direction a, and the first direction a is the depth direction of the receiving chamber 11. The distribution box can solve the problems of complex wiring and messy wiring of the strong current control line and the weak current control line in the distribution box in the prior art, and enables the strong current control line and the weak current control line to be routed in any direction, which can meet the wiring requirements of different working conditions.

[0038] The box 10 provided in the present application can accommodate strong current devices and weak current devices. It should be noted that the box 10 can be provided with a first placement area and a second placement area. The first placement area can be used to place strong current devices, and the second placement area can be used to place weak current devices. The first placement area and the second placement area can be part of the accommodating cavity 11 of the box 10, or can be formed by other structures accommodated in the box 10. For example, the first placement area can be formed by Figure 4 The second placement area can be formed by the inner cavity of the high-voltage box 30 shown. Figure 4 The inner cavity of the weak-current box 40 shown is formed, and the present application does not limit the specific method for placing strong-current components and weak-current components.

[0039] The box 10 has a housing chamber 11, which at least includes the above-mentioned strong current wiring area 12 and weak current wiring area 13, and the strong current wiring area 12 and the weak current wiring area 13 do not intersect in space. That is, the strong current wiring area 12 and the weak current wiring area 13 are isolated from each other, so that the problem of messy wiring of the strong current control line and the weak current control line can be avoided, and the wiring operation of the strong current control line and the weak current control line can be simplified.

[0040] Specifically, the present application realizes the mutual isolation between the strong current wiring area 12 and the weak current wiring area 13 by providing a partition 20 between the strong current wiring area 12 and the weak current wiring area 13 .

[0041] It should be noted that the shape of the partition 20 is not specifically limited in this application, and can be adaptively set according to the shapes of the strong current wiring area 12 and the weak current wiring area 13. In this embodiment, the partition 20 is preferably an insulating plate to reduce the risk of short circuit of the control lines of the strong current wiring area 12 and the weak current wiring area 13.

[0042] In addition, in the present embodiment, the strong-current wiring area 12 and the weak-current wiring area 13 are arranged in staggered layers in the first direction a. That is, the strong-current wiring area 12 and the weak-current wiring area 13 are distributed along the first direction a (for example, the strong-current wiring area 12 is located in the upper layer, and the weak-current wiring area 13 is located in the lower layer; or, the weak-current wiring area 13 is located in the upper layer, and the strong-current wiring area 12 is located in the lower layer). Through this staggered arrangement, the present application can make the strong-current control line of the strong-current wiring area 12 and the weak-current control line of the weak-current wiring area 13 realize the outlet in any direction, so as to solve the problem that the strong-current control line and the weak-current control line can only enter and exit in the same direction in the prior art, so that the distribution box provided by the present application can meet the wiring requirements of different working conditions.

[0043] To summarize, the distribution box provided in the present application includes a box body 10 and a partition 20; the box body 10 has a accommodating cavity 11, and a high-voltage wiring area 12 and a low-voltage wiring area 13 are provided in the accommodating cavity 11. The partition 20 is provided between the high-voltage wiring area 12 and the low-voltage wiring area 13, and is used to separate the high-voltage wiring area 12 and the low-voltage wiring area 13. The high-voltage wiring area 12 and the low-voltage wiring area 13 are staggered in a first direction a, and the first direction a is the depth direction of the accommodating cavity 11. The present application divides the accommodating cavity 11 of the box body 10 into a strong current wiring area 12 and a weak current wiring area 13, and sets a partition 20 between the strong current wiring area 12 and the weak current wiring area 13, so that the strong current wiring area 12 and the weak current wiring area 13 can be isolated from each other, so that the strong current control line arranged in the strong current wiring area 12 and the weak current control line arranged in the weak current wiring area 13 can be set independently, and the strong current control line and the weak current control line will not be intertwined with each other, which can solve the problem of complex wiring and messy wiring of the strong current control line and the weak current control line in the distribution box in the prior art; and because the strong current wiring area 12 and the weak current wiring area 13 are arranged in staggered layers, the strong current control line and the weak current control line can also be connected in any direction to meet the wiring requirements of different working conditions.

[0044] like Figure 4 As shown, in this embodiment, the strong current wiring area 12 and the weak current wiring area 13 are arranged along the first direction a, and the first direction a is the depth direction of the accommodating cavity 11. In other words, the strong current wiring area 12 and the weak current wiring area 13 are stacked up and down, so that the strong current control lines in the strong current wiring area 12 and the weak current control lines in the weak current wiring area 13 belong to different levels and will not be intertwined.

[0045] Of course, in other feasible implementations, such as Figure 1 As shown, based on the staggered arrangement of the high-current wiring area 12 and the low-current wiring area 13 along the first direction a, the orthographic projections of the high-current wiring area 12 and the low-current wiring area 13 on the box 10 along the first direction a can also be arranged along the second direction b, and the second direction b is perpendicular to the depth direction of the accommodating cavity 11.

[0046] That is to say, in this case, the high-voltage wiring area 12 and the low-voltage wiring area 13 are stacked up and down, and the positive projections of the high-voltage wiring area 12 and the low-voltage wiring area 13 on the box body 10 are arranged side by side. Since the partition 20 is located between the high-voltage wiring area 12 and the low-voltage wiring area 13, this method will not cause the high-voltage control line and the low-voltage control line to be intertwined.

[0047] Please refer to Figure 1 and Figure 4Optionally, the distribution box also includes a strong current box 30 and a weak current box 40, which are respectively arranged in the accommodating cavity 11 and arranged side by side. The strong current box 30 is used to accommodate strong current devices, and the weak current box 40 is used to accommodate weak current devices; the strong current box 30 is connected to the strong current wiring area 12, and the weak current box 40 is connected to the weak current wiring area 13.

[0048] The strong current box 30 is connected to the strong current wiring area 12, so that the strong current control line can be connected to the strong current device at one end and connected to the strong current wiring area 12 at the other end; the weak current box 40 is connected to the weak current wiring area 13, so that the weak current control line can be connected to the weak current device at one end and connected to the weak current wiring area 13 at the other end. Of course, it should be noted that the present application may not set the strong current box 30 and the weak current box 40. Fig.11 As shown, in this way, the box body 10 can also be used to accommodate strong current devices and weak current devices.

[0049] It should be noted that when the distribution box has a strong current box 30 and a weak current box 40, and the strong current wiring area 12 and the weak current wiring area 13 are arranged along the first direction a, as shown in FIG. Figure 5 As shown, if the high-current wiring area 12 is located below the low-current wiring area 13, then the low-current wiring area 13 can be located in the low-current box 40, and the bottom plate of the low-current box 40 can serve as the partition 20; of course, if the high-current wiring area 12 is located above the low-current wiring area 13, then the high-current wiring area 12 can be located in the high-current box 30, and the bottom plate of the high-current box 30 can serve as the partition 20.

[0050] In addition, when the strong current box 30 and the weak current box 40 of the distribution box are arranged side by side, the board of the weak current box 40 close to the strong current box 30 can serve as the function of the partition 20, such as Figure 4 Of course, a separate board can also be made between the strong current box 30 and the weak current box 40 as the partition 20.

[0051] It should be understood that the above two methods are only examples. In other embodiments, the high-voltage wiring area 12 and the low-voltage wiring area 13 may also be located in the accommodating cavity 11 of the box body 10 and arranged outside the high-voltage box 30 and the low-voltage box 40.

[0052] like Figure 5 As shown, optionally, the size of the strong current box 30 along the first direction a is different from the size of the weak current box 40 along the first direction a, and the first direction a is the depth direction of the accommodating cavity 11. The above arrangement is particularly conducive to the arrangement of the strong current wiring area 12 and the weak current wiring area 13 along the first direction a.

[0053] Of course, when the orthographic projections of the high-voltage wiring area 12 and the low-voltage wiring area 13 on the box body 10 are still arranged along the second direction b, the high-voltage wiring area 12 can be set below the high-voltage box 30, and the low-voltage wiring area 13 can be set below the low-voltage box 40; or, the high-voltage wiring area 12 and the low-voltage wiring area 13 can also be set below a relatively smaller component of the two (i.e., the smaller component of the high-voltage box 30 and the low-voltage box 40).

[0054] Alternatively, if Figure 5 , the size of the strong current box 30 along the first direction a is greater than the size of the weak current box 40 along the first direction a. It should be understood that the size of the strong current box 30 along the first direction a is greater than the size of the weak current box 40 along the first direction a is only an example, and in other embodiments, the size of the weak current box 40 along the first direction a may also be greater than the size of the strong current box 30 along the first direction a.

[0055] like Figure 5 As shown, optionally, the strong current wiring area 12 and the weak current wiring area 13 are both located between the weak current box 40 and the bottom wall of the accommodating cavity 11. In this way, the space of the accommodating cavity 11 in the box body 10 can be effectively utilized by taking advantage of the fact that the size of the strong current box 30 along the first direction a is larger than the size of the weak current box 40 along the first direction a.

[0056] Also, if Figure 5 As shown, there is a gap between the strong current box 30 and the weak current box 40 and the bottom wall of the accommodating cavity 11. This is beneficial to heat dissipation and the arrangement of the strong current wiring area 12 and the weak current wiring area 13.

[0057] like Figure 7 As shown, a first support member 61 and a second support member 62 may be protruded on the bottom wall of the accommodating cavity 11 of the box body 10, the first support member 61 being used to support the strong current box 30, and the second support member 62 being used to support the weak current box 40. The sizes of the first support member 61 and the second support member 62 may be determined according to the size of the gaps between the strong current box 30 and the weak current box 40 and the bottom wall of the accommodating cavity 11, respectively, and the present application does not impose any specific limitation.

[0058] Alternatively, if Figure 4 The first hollow area 51 is respectively provided on the side of the strong current box 30 away from the weak current box 40 and the side of the weak current box 40 away from the strong current box 30. In this way, the strong current control line can enter and exit along the side away from the weak current box 40, and the weak current control line can enter and exit along the side away from the strong current box 30.

[0059] Of course, if the size of the strong current box 30 along the first direction a is larger than the size of the weak current box 40 along the first direction a, a first hollow area 51 can also be set on the side of the strong current box 30 close to the weak current box 40, so that the strong current control line can enter and exit along the arrangement direction of the strong current box 30 and the weak current box 40. It can further improve the diversity of wiring and expand the application scenarios of the distribution box. It should be understood that if the size of the weak current box 40 along the first direction a is larger than the size of the strong current box 30 along the first direction a, then correspondingly, a first hollow area 51 can be set on the side of the weak current box 40 close to the strong current box 30.

[0060] Optionally, second hollow areas are respectively provided on the opposite sides of the high-current box 30 along the second direction b and on the opposite sides of the low-current box 40 along the second direction b, and the second direction b, the depth direction of the accommodating cavity 11, and the arrangement directions of the high-current box 30 and the low-current box 40 are perpendicular to each other.

[0061] In this way, both the high-voltage control line and the low-voltage control line can enter and exit along the second direction b, which can further improve the diversity of wiring.

[0062] It should be noted that the first hollow area 51 and the second hollow area may be a whole piece of hollow, such as Figure 4 and Figure 6 , and can also be composed of multiple threading holes.

[0063] To facilitate the assembly of the strong current box 30 and the weak current box 40 with the box body 10 , optionally, the box body 10 supports the strong current box 30 , and the strong current box 30 supports the weak current box 40 ; or, the box body 10 supports the weak current box 40 , and the weak current box 40 supports the strong current box 30 .

[0064] For example, the strong current box 30 can be mounted on the box body 10, and the weak current box 40 can be mounted on the strong current box 30. Figures 8 to 10 Or, the weak current box 40 is hung on the box body 10, and the strong current box 30 is hung on the weak current box 40.

[0065] When the strong current box 30 is mounted on the box body 10 and the weak current box 40 is mounted on the strong current box 30, please refer to Fig. 9 A first hanging portion 31 can be provided on one side of the strong electric box 30, and a Figure 8 The first matching portion 14 shown can be hooked with the first hooking portion 31. A second matching portion 32 is provided on one side of the strong current box 30 close to the weak current box 40, and a second hooking portion 41 adapted to the second matching portion 32 is provided on the weak current box 40, and the second hooking portion 41 can be hooked on the second matching portion 32.

[0066] When the weak current box 40 is hung on the box body 10 and the strong current box 30 is hung on the weak current box 40 , the same logic can be applied and this application will not elaborate on this.

[0067] For another example, the high-current box 30 can be pulled out and set on the box body 10, and the low-current box 40 is hung on the high-current box 30; or, the low-current box 40 can be pulled out and set on the box body 10, and the high-current box 30 is hung on the low-current box 40.

[0068] Another aspect of the present invention provides a power distribution system, which includes the above-mentioned power distribution box. Since the specific structure and technical effects of the power distribution box have been elaborated and explained in detail above, this application will not repeat them here.

[0069] The above description is only an optional 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.

[0070] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction.
