Description

Technical Field

[0001] The utility model relates to the field of combiner cabinets, in particular to a cable inlet arrangement structure and a combiner cabinet. Background Art

[0002] At present, the inlet and outlet lines of the low-voltage DC combiner cabinet on the market are generally connected in series with a fuse in each cluster of power cables in the container through the high-voltage box, and then output to the disconnector by the disconnector. If there are 12 clusters, 12 fuses need to be connected in series, and sufficient space must be guaranteed between each fuse, that is, at least 30mm of operating space must be guaranteed between each fuse for the installation and after-sales maintenance and replacement of the fuse. This will result in the need to deepen or widen the outer dimensions of the combiner cabinet to meet the installation requirements of the fuse, which will make the combiner cabinet larger in size, which is not conducive to the selection and arrangement of the battery compartment, liquid cooling unit and other devices. In addition, the number of cable clusters for each project is different, and the size of the combiner cabinet required to be increased is also different, which is not conducive to the standardized design of the product and greatly increases the production cost.

[0003] Therefore, a cable entry arrangement structure and a junction box are needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a cable incoming line arrangement structure and a junction box, so as to optimize the cable arrangement mode, shorten the space occupied by the fuse in the depth or width direction of the junction box, and meet the installation requirements of the fuse and the arrangement of the cable under the premise of a standardized junction box, thereby achieving the purpose of reducing costs.

[0005] In order to solve the above technical problems, the utility model provides a cable inlet arrangement structure, including a base plate, a busbar, a fuse group and a cable body;

[0006] The busbar is arranged on the substrate;

[0007] The fuse group is arranged on the upper and lower sides of the busbar and includes a plurality of fuse bodies;

[0008] One end of the cable body is connected in series with the fuse body and is connected to the busbar.

[0009] Furthermore, the busbar is provided with double rows of connection holes;

[0010] The number of the connection holes in each row matches the number of the fuse bodies in the fuse group.

[0011] Furthermore, the connecting hole and the corresponding fuse body are located in the same vertical plane.

[0012] Furthermore, the connection hole is built with a bolt fastener for connecting the busbar and the fuse body.

[0013] Furthermore, the two fuse groups are symmetrically arranged on the upper and lower sides of the busbar.

[0014] Furthermore, a fixed beam is provided on the base plate;

[0015] One end of the fuse body is locked on the fixed crossbeam by means of bolts.

[0016] Furthermore, the fuse group includes three fuse bodies.

[0017] On the other hand, the utility model also provides a combiner cabinet, comprising a cabinet body and the cable inlet arrangement structure described in the above embodiment;

[0018] The base plate is a side plate of the cabinet.

[0019] Furthermore, an opening is preset at the bottom of the cabinet, and the opening is used for the cable body to pass through.

[0020] Furthermore, the plurality of cable bodies are vertically arranged inside the cabinet.

[0021] Compared with the prior art, the utility model has at least the following beneficial effects:

[0022] By arranging fuse groups on the upper and lower sides of the busbar, the fuse bodies are placed in a stacked manner, and by connecting the cable body in series with the fuse body and then connecting it to the busbar, the cable body can be installed by entering the cable from top to bottom. Therefore, through this arrangement, it is possible to effectively reduce the excess space in the depth or width direction of the busbar cabinet due to the need to connect the cable body in series with the fuse body and the need to reserve operating space between the two fuse bodies, so that the busbar cabinet can meet the functional requirements of installing cables and other components within the specified size range, which is conducive to the standardized design of the busbar cabinet, and achieves the purpose of reducing costs, simplifying processes and facilitating installation. Correspondingly, sufficient space can be reserved for the selection of other components such as battery compartments and liquid cooling units. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The cable inlet arrangement structure and the combiner cabinet of the utility model will be described in more detail below in conjunction with the schematic diagram, wherein the preferred embodiment of the utility model is shown. It should be understood that the technical personnel in the field can modify the utility model described herein, and still achieve the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to the technical personnel in the field, and not as a limitation to the utility model.

[0028] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0029] In the prior art, the cable entry arrangement structure often adopts a single-row entry, that is, by setting a row of fuse bodies 3, and installing a busbar 2 below or above the fuse body 3, so that the cable body 4 is connected in series with the fuse body 3 from the side of the fuse body 3 away from the busbar 2, and then connected to the busbar 2. However, in actual application, this method will require a corresponding expansion of the depth of the busbar cabinet due to the increase in the number of fuse bodies 3, which will lead to an increase in the production cost of the busbar cabinet, and due to different requirements, the corresponding number of fuse bodies 3 is also different, and the busbar cabinet needs to be customized, so it is difficult to achieve standardized production, which is not conducive to saving production costs.

[0030] To this end, this embodiment proposes a cable entry structure, which optimizes the arrangement of the fuse body 3 and the cable body 4 to meet the installation requirements, improve space utilization, and reduce costs under the premise of a standardized junction cabinet.

[0031] Embodiment 1

[0032] like Figures 1 to 3 As shown, an embodiment of the utility model proposes a cable inlet arrangement structure, including a substrate 1, a busbar 2, a fuse group and a cable body 4.

[0033] The busbar 2 is arranged on the substrate 1, that is, fixedly mounted on the substrate 1. The busbar 2 plays a vital role in power engineering and electrical systems by balancing voltage and connecting electrical equipment, ensuring the safe operation of the system and effective grounding of the equipment.

[0034] The fuse group is arranged on the upper and lower sides of the busbar 2, and includes a plurality of fuse bodies 3. That is, the fuse bodies 3 are arranged on the substrate 1 in an up-and-down stacking manner, so the space required in the width direction of the substrate 1 (i.e., the depth direction of the busbar cabinet) can be effectively saved. Compared with the single-row arrangement in the prior art, the situation that the substrate 1 needs to be widened (the busbar cabinet needs to be deepened) due to too many fuse bodies 3 can be effectively avoided.

[0035] One end of the cable body 4 is connected in series with the fuse body 3 and is connected to the bus bar 2 to complete the wiring function of the cable body 4. Since the fuse body 3 is arranged in a stacked shape, the cable body 4 can be installed by means of upper and lower wire outlets, that is, the normal wiring function of the cable body 4 will not be affected by the change in the arrangement of the fuse body 3.

[0036] The device arranges fuse groups on the upper and lower sides of the busbar 2 so that the fuse bodies 3 are placed in a stacked manner, and connects the cable bodies 4 in series with the fuse bodies 3 and then to the busbar 2, so that the cable bodies 4 can be installed by means of upper and lower line entry. Therefore, through this arrangement, it is possible to effectively reduce the redundant space generated in the depth or width direction (i.e., the width of the substrate 1) of the busbar cabinet due to the need to connect the cable bodies 4 in series with the fuse bodies 3 and the need to reserve operating space between the two fuse bodies 3, so that the busbar cabinet can meet the functional requirements of installing components such as cables within the specified size range, which is conducive to the standardized design of the busbar cabinet, and achieves the purpose of reducing costs, simplifying processes and facilitating installation. Correspondingly, sufficient space can be reserved for the selection of other components such as battery compartments and liquid cooling units.

[0037] It should be noted that the busbar 2 is provided with double rows of connection holes.

[0038] The number of the connection holes in each row matches the number of the fuse bodies 3 in the fuse group, so that the fuse bodies 3 can correspond to the connection holes one by one.

[0039] In addition, the connection hole and the corresponding fuse body 3 are located in the same vertical plane, which facilitates connection.

[0040] It should be noted that the connection hole is equipped with a bolt fastener for connecting the busbar 2 and the fuse body 3 .

[0041] In a further embodiment, the two fuse groups are symmetrically arranged on the upper and lower sides of the busbar 2 , so that the two fuse groups can be better connected to the busbar 2 .

[0042] In other embodiments, in order to facilitate the fixed installation of the fuse group on both sides of the busbar 2, a fixed crossbeam 5 is provided on the substrate 1.

[0043] It should be noted that one end of the fuse body 3 is fastened to the fixed crossbeam 5 by means of bolts.

[0044] In this embodiment, the fuse group includes three fuse bodies 3 to meet the wiring requirements of six clusters of cable bodies 4. The fuse group may also include four, five or six fuse bodies 3 to meet the wiring requirements of eight clusters of cable bodies 4, ten clusters of cable bodies 4 or twelve clusters of cable bodies 4, respectively.

[0045] Embodiment 2

[0046] This embodiment further proposes a combiner cabinet based on the first embodiment, which effectively controls the length and depth of the cabinet body 6, reduces the volume of the combiner cabinet, improves space utilization, and achieves the purpose of reducing the manufacturing cost of the combiner cabinet.

[0047] like Figure 2 and Figure 3 As shown, specifically, a junction box includes a box body 6 and the cable inlet arrangement structure described in the first embodiment.

[0048] The base plate 1 is a side plate of the cabinet 6 .

[0049] It should be particularly noted that the combiner cabinet proposed in this embodiment is a double-pole combiner cabinet, so two side panels are arranged in the middle. Correspondingly, four groups of cable inlet arrangement structures are arranged in the cabinet body 6 to meet application requirements.

[0050] It should also be noted that the bottom of the cabinet 6 is preset with an opening, which is used for the insertion of the cable body 4, so that multiple cable bodies 4 are arranged vertically inside the cabinet 6, which is convenient for laying the cable bodies 4 and easy for installation.

[0051] The device arranges the fuse bodies 3 in a stacked manner, so that the space occupied by the busbars 2 in the depth direction of the cabinet 6 due to the single-row arrangement of the fuse bodies 3 can be effectively shortened, so as to effectively control the length and depth of the cabinet 6. Since the cable bodies 4 can be connected by upper and lower wire entry, this arrangement can effectively reduce the volume of the busbar cabinet, improve space utilization, and achieve the purpose of reducing the manufacturing cost of the busbar cabinet.

[0052] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
