Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to a busbar protective housing structure and device. Background Technology

[0002] In existing technologies, busbars, commonly known as copper busbars, are the core conductive components connecting power sources and loads in low-voltage distribution cabinets, switchgear, and various electrical equipment. Because exposed busbars may pose safety hazards and are susceptible to factors such as dust, moisture, and corrosion, effective protection and insulation are necessary. Currently, protective enclosures for busbars are commonly used in the market to address this issue.

[0003] However, most of the bus enclosures in the existing technology are designed with one-piece molding or fixed size. This fixed structure can only accommodate the length and width of bus of specific specifications. When the power distribution system design changes and different sizes or higher current loads need to be installed, i.e., a larger cross-sectional area bus is required, the designer must re-customize or find new matching enclosures, which increases the complexity of design and inventory. Utility Model Content

[0004] To address the aforementioned issues, this application provides a busbar protective housing structure and device that utilizes a modular splicing structure for the base and a convenient opening and closing design for the side baffles, while simultaneously enabling free expansion of the protective housing size and busbar wiring operations.

[0005] To achieve the above objectives, in a first aspect, embodiments of this application provide a busbar protective housing structure, comprising: A base, at least one side wall of which is provided with a splicing structure for splicing with another identical base; The top cover is detachably connected to the base, and the base and the top cover together define a receiving space for accommodating the busbar; At least one side stop, the receiving space having a lateral opening corresponding to the side stop, the side stop being detachably mounted on the top cover to selectively close the lateral opening.

[0006] Preferably, the splicing structure includes a splicing protrusion and a splicing groove provided on the side wall of the base.

[0007] Preferably, the bottom edge of the top cover has a notch forming the lateral opening, the opening of the notch is downward, and the inner wall of the notch has a groove for guiding the side stop to slide, the side stop being an insert structure that is inserted and fixed to the groove.

[0008] Preferably, the top cover has four side walls, each of which is provided with a groove to slide and install a side stop member to close the four lateral openings of the accommodating space.

[0009] Preferably, the upper cover and the base are detachably connected by fasteners.

[0010] Preferably, the four corners of the top cover are recessed with recesses, and the recesses are detachably connected to the base by a fastener.

[0011] Preferably, it further includes a cushioning pad, which is disposed on the side of the base opposite to the top cover.

[0012] Preferably, the width of the lateral opening is greater than the width of the busbar housed within the receiving space.

[0013] Secondly, embodiments of this application provide a busbar protection device, including at least two busbar protection housing structures as described in any of the embodiments of the first aspect; wherein the bases of two adjacent busbar protection housing structures are spliced ​​together by their splicing structure.

[0014] The busbar protective housing structure and device designed in this application achieve modular free expansion by setting a splicing structure on the side wall of the base, and setting a detachable side baffle to open the lateral wiring space. This solves the problems of fixed housing size and poor versatility of the existing housing, and can flexibly adapt to different specifications of busbars to meet high load applications. At the same time, its wiring operation does not require disassembling the entire top cover, which effectively simplifies the installation and maintenance steps and improves on-site construction efficiency.

Detailed Implementation

[0022] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0023] Firstly, embodiments of this application provide a busbar protective housing structure 100. For example... Figures 1 to 4 As shown, the structure mainly includes a base 10, a top cover 30, and at least one side baffle 40. The top cover 30 is detachably covered on the base 10 to cooperate with the base 10 to form a receiving space for accommodating the busbar.

[0024] Specifically, to achieve modular splicing of multiple protective shell structures, at least one side wall of the base 10 is provided with a splicing structure 20; this splicing structure 20 is used to cooperate and connect with another splicing structure 20 of the same base 10. In a preferred embodiment, such as Figure 2 , Figure 4 As shown, the splicing structure 20 may include splicing protrusions 21 and splicing grooves 22 alternately arranged on the side wall of the base 10. For example, the splicing groove 22 may be designed as a dovetail groove structure, while the splicing protrusion 21 may be designed as a dovetail tenon structure adapted to the dovetail groove structure, thereby achieving a stable insertion between adjacent bases 10.

[0025] To facilitate wiring operations on the busbars within the accommodating space, a lateral opening 50 is formed between the upper cover 30 and the base 10. In this embodiment, a removable side stop 40 is provided to selectively close the lateral opening 50. In one specific implementation, such as... Figure 2 As shown, the edge of the upper cover 30 extends downward to form a skirt 31, and a groove 60 is formed on the inner wall of the skirt 31 to guide the side stop 40 to slide. The side stop 40 is preferably a one-sided sliding plate structure, which can be easily installed or removed along the groove 60. When wiring is required, only the side stop 40 in the corresponding position needs to be slid out or removed, without disassembling the entire upper cover 30, making the operation extremely convenient.

[0026] Preferably, such as Figure 2 , Figure 4As shown, the upper cover 30 has a quadrilateral structure with four side walls. Each of the four side walls is provided with the aforementioned skirt 31 and sliding groove 60, so as to install four side baffles 40 respectively, in order to close the four lateral openings 50 of the accommodating space, thereby achieving comprehensive protection and selective opening of the accommodating space.

[0027] In some embodiments, such as Figure 2 As shown, a notch forming the lateral opening 50 is provided at the bottom edge of the upper cover 30. The opening of the notch faces downward, and a groove 60 for guiding the side stop 40 to slide is recessed on the inner wall of the notch. Specifically, the notch is provided on the skirt 31 at the edge of the upper cover 30, and its downward opening ensures that when the upper cover 30 and the base 10 are assembled together, the side stop 40 inserted into the groove 60 is blocked by the position of the base 10 and cannot be dislodged.

[0028] In some embodiments, such as Figure 2 As shown, the upper cover 30 and the base 10 are detachably connected by fasteners 70. In specific implementations, such as... Figure 1 , Figure 2 As shown, the upper cover 30 has recessed portions 32 at its four corners, and each recessed portion 32 is detachably connected to the base 10 by a fastener 70. The fastener 70, such as a fixing screw, can pass through the recessed portion 32 and cooperate with the nut fixed on the base 10, thereby fastening the upper cover 30 and the base 10 together.

[0029] In some embodiments, such as Figure 4 As shown, it also includes a cushioning pad 80, which is disposed on the side of the base 10 opposite to the upper cover 30. In this embodiment, the cushioning pad 80 is made of foam.

[0030] In some embodiments, the width of the lateral opening 50 is greater than the width of the bus housed within the receiving space. This ensures, on the one hand, that the bus and its side terminals can be fully exposed after the side baffle 40 is removed, facilitating cable tightening or loosening operations; on the other hand, when providing protection for busbars of different lengths, the busbar can extend beyond the lateral opening 50 to allow for assembly using multiple busbar protective housing structures 100.

[0031] Secondly, such as Figure 4 , Figure 5As shown, this application provides a busbar protection device 200, including at least two busbar protection housing structures 100 as described in any of the first aspects embodiments; wherein, the bases 10 of two adjacent busbar protection housing structures 100 are spliced ​​together by their splicing structures 20. In use, the user can arrange multiple busbar protection housing structures 100 side by side or in an array according to the actual size and layout requirements of the busbar, and splice them together by the splicing structures 20 on each base 10 to form an integral, expandable protective structure.

[0032] The busbar protective housing structure and device provided in this application embodiment achieve modular free expansion by setting a splicing structure on the side wall of the base, and setting a detachable side baffle to open the lateral wiring space. This solves the problems of fixed housing size and poor versatility of the existing housing, and can flexibly adapt to different specifications of busbars to meet high load applications. At the same time, its wiring operation does not require disassembling the entire top cover, which effectively simplifies the installation and maintenance steps and improves on-site construction efficiency.
