Description

Technical Field

[0001] This utility model belongs to the field of busbar technology in electrical engineering, and particularly relates to a C-type busbar structure. Background Technology

[0002] Intelligent miniature busbars are devices primarily used in data centers and low-voltage electrical rooms for power supply and distribution. They typically consist of a starting box, a main trunk, and a plug-in box. The main trunk generally comprises an aluminum-magnesium alloy shell, internal copper busbars, and insulators, while the plug-in box typically consists of a distribution box and plug connectors.

[0003] In existing product designs, the copper busbars inside busbar troughs are typically long, strip-shaped copper conductors, while the connectors are generally rectangular or arc-shaped copper blocks. During use, the connector is inserted upwards into the busbar trough and rotated 90 degrees to bring it into contact with the copper busbar, thus completing the power connection. However, this connection has a certain problem: the structural design of the copper busbars and connectors limits their contact area, resulting in situations where the other side of the connector cannot be fully utilized.

[0004] Existing technology discloses a "Smart Busbar Trunking for Data Centers" (Publication No. CN109149476A). The copper busbars inside the busbar are designed with a two-layer, gradually opening structure, and the connectors are designed as flat copper strips. During insertion, the connectors are still inserted upwards into the busbar trough, and rotated 90 degrees to ensure reliable contact between both sides of the connector and the copper busbars inside the busbar. While this structure avoids the problem of low surface utilization when the connector contacts the copper busbars and has the advantages of a tighter fit and smaller size, this compact and narrow structure also suffers from poor heat dissipation. Temperature is a crucial factor in ensuring the stability, reliability, and safety of the power supply system. Poor heat dissipation inevitably leads to a reduction in current carrying capacity, and a prolonged poor heat dissipation environment will further degrade insulation, potentially causing accidents. Utility Model Content

[0005] In view of the shortcomings of the related technologies, this utility model provides a C-type busbar trunking structure to solve the problem that the current busbar trunking structure cannot simultaneously achieve efficient utilization of the connector surface and good heat dissipation performance.

[0006] This utility model provides a C-type busbar trunking structure, including:

[0007] The busbar trunking has an insulating support installed on its inner wall.

[0008] The conductive busbar is mounted on an insulating support; the cross-section of the conductive busbar is C-shaped, so that its upper and lower ends are bent vertically toward the plug-in side;

[0009] The plug box has a rotatable plug; the plug extends into the busbar trunking.

[0010] A conductive connector is installed on a plug connector; by rotating the plug connector, the conductive connector is inserted into the conductive busbar, and the end face and the upper and lower side surfaces of the conductive connector are in contact with the surface of the conductive busbar.

[0011] In some embodiments, conductive connectors are symmetrically installed on the left and right sides of the plug, and conductive busbars are symmetrically installed on the left and right sides of the busbar trunking.

[0012] Rotary connectors, each conductive connector is inserted into a corresponding conductive busbar.

[0013] In some embodiments, the end face of the conductive connector is an arc surface.

[0014] In some embodiments, the insulating support includes:

[0015] Back plate, installed on the busbar trunking;

[0016] Ribs are vertically connected to the back plate; multiple ribs are spaced apart, and the ribs are divided into two fixed ribs located on the upper and lower sides of the conductive busbar and a supporting rib located between the two fixed ribs; the two fixed ribs clamp the fixed conductive busbar, and the supporting rib is attached to the surface of the conductive busbar away from the connector, so as to create a gap between the back plate and the conductive busbar.

[0017] In some embodiments, the fixing ribs are provided with clamping ribs protruding toward the conductive busbar side, and the clamping ribs are attached to the conductive busbar so that the fixing ribs and the conductive busbar are spaced apart.

[0018] In some embodiments, the end face of the fixing rib away from the back plate is flush with the end face of the conductive busbar near the connector.

[0019] In some embodiments, the inner wall of the busbar trunking is vertically provided with wing plates, and multiple wing plates are spaced apart.

[0020] Wings are divided into fixed wings and supporting wings;

[0021] The fixed wing plate extends to the surface of the insulating bracket near the plug, and presses and fixes the insulating bracket against the inner wall of the busbar trough.

[0022] The support wing plate is attached to the surface of the insulating bracket away from the plug, so as to keep the insulating bracket spaced apart from the inner wall of the busbar trough.

[0023] The insulating bracket has fixed wing plates on both the upper and lower sides, and the supporting wing plates are located between adjacent fixed wing plates.

[0026] Rotate the connector, with the end face of the first grounding connector attached to the grounding busbar inside the slot, and the end face of the second grounding connector attached to the grounding busbar on the casing.

[0027] In some embodiments, the first grounding connector and the second grounding connector are symmetrically arranged on the plug; the in-slot grounding busbar and the shell grounding busbar are symmetrically arranged on the left and right sides in the busbar trunking.

[0028] Compared with the prior art, the beneficial effects of this application are as follows: In the embodiment of this utility model, the conductive busbar is C-shaped, so that when the conductive connector is inserted and electrically connected to it, the three sides of the conductive connector are in contact with the conductive busbar, which makes efficient use of the surface of the conductive connector and can carry more current. At the same time, the conductive busbar has an open structure and a larger heat dissipation area, avoiding the reduction of current carrying capacity and insulation degradation caused by high temperature of the conductive busbar. This solves the problem that the current busbar structure cannot take into account both efficient utilization of the connector surface and good heat dissipation performance.

[0037] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] In the description of this utility model, it should be understood that the terms "center", "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] like Figures 1 to 2 As shown, in one schematic embodiment of the C-type busbar trunking structure of this utility model, the C-type busbar trunking structure includes a busbar trunking body 1, a conductive busbar 2, a plug-in box 3, and a conductive connector 4.

[0042] The plug-in box 3 has a rotatable plug-in 5, which extends into the busbar trunking 1 through an opening. An insulating support 6 is installed on the inner wall of the busbar trunking 1, and a conductive busbar 2 is mounted on the insulating support 6. The upper and lower ends of the conductive busbar 2 are bent vertically towards the plug-in 5, making the cross-section of the conductive busbar 2 C-shaped. A conductive connector 4 is mounted on the plug-in 5.

[0043] Because the opening width of the busbar trunking 1 is smaller than the width of the connector 5, but larger than the thickness of the connector 5, the connector 5 needs to be rotated 90 degrees after being inserted into the busbar trunking 1 so that the conductive connector 4 can be attached to the conductive busbar 2. Since the conductive busbar 2 has a C-shaped cross-section, the conductive connector 4 is inserted into the conductive busbar 2, with the conductive busbar 2 surrounding the conductive connector 4 on three sides. The end face and upper and lower side surfaces of the conductive connector 4 are all in contact with the surface of the conductive busbar 2.

[0044] The conductive connector 4 has three sides that are in contact with the conductive busbar 2, making full use of the surface of the conductive connector 4 so that the electrical connection between the conductive connector 4 and the conductive busbar 2 can carry more current. In addition, the C-shaped conductive busbar 2 has a more open structure and a larger heat dissipation area, which can avoid the reduction of current carrying capacity and insulation degradation caused by high temperature of the conductive busbar 2.

[0045] In some embodiments, conductive connectors 4 are symmetrically installed on both sides of the plug 5, and conductive busbars 2 are symmetrically installed on both sides of the busbar trunking 1. By rotating the plug 5, each conductive connector 4 is inserted into a corresponding conductive busbar 2. This structural design ensures that the conductive connectors 4 and conductive busbars 2 are arranged symmetrically from left to right, and each conductive connector 4 is matched with a conductive busbar 2. This allows the plug 5 to be rotated 180 degrees, enabling the conductive connector 4 on one side to be switched to the conductive busbar 2 on the other side, thus achieving the interchangeability of the conductive connectors 4 inserted into the conductive busbars 2 on both sides, satisfying the function of switching the conductive circuit, and improving the flexibility of use.

[0046] In some embodiments, the end face of the conductive connector 4 is an arc surface. This structural design allows the conductive connector 4 to make uniform and smooth contact with the conductive busbar 2 when the connector 5 rotates, avoiding frictional wear and extending service life.

[0047] In some embodiments, the insulating support 6 includes a back plate 601 and ribs 602. The back plate 601 is mounted on the busbar trunking 1, and the ribs 602 are vertically connected to the back plate 601. Multiple ribs 602 are spaced apart, and each rib 602 is divided into two fixed ribs 6021 located on the upper and lower sides of the conductive busbar 2, and a supporting rib 6022 located between the two fixed ribs 6021. The two fixed ribs 6021 clamp and fix the conductive busbar 2, and the supporting rib 6022 is attached to the surface of the conductive busbar 2 away from the connector 5, so as to create a gap between the back plate 601 and the conductive busbar 2.

[0048] This structural design enables the insulating bracket 6 to install and fix the conductive busbar 2. At the same time, the ribs 602 form a heat dissipation channel on the side of the conductive busbar 2 away from the connector 5. This allows the heat generated by the conductive busbar 2 to be dissipated not only through the surface facing the connector 5 to the internal space of the busbar trunking 1, but also through the surface away from the connector 5 to the heat dissipation channel formed by the insulating bracket 6. This achieves heat dissipation from both sides of the conductive busbar 2, improving heat dissipation efficiency.

[0049] In some embodiments, the fixing ribs 6021 are all provided with clamping ribs 6023 protruding toward the conductive busbar 2. The clamping ribs 6023 are all attached to the conductive busbar 2 so that the fixing ribs 6021 and the conductive busbar 2 are spaced apart.

[0050] This structural design allows both fixing ribs 6021 to clamp and fix the conductive busbar 2 through clamping ribs 6023. The clamping ribs 6023 enhance the strength of the fixing ribs 6021, while exposing the upper and lower surfaces of the conductive busbar 2 to the heat dissipation channels formed by the insulating bracket 6, increasing the heat dissipation area of ​​the conductive busbar 2 away from the connector 5, and further improving the heat dissipation efficiency.

[0051] In some embodiments, the end face of the fixing rib 6021 away from the back plate 601 is flush with the end face of the conductive busbar 2 near the connector 5. This structural design allows the conductive busbar 2 to be installed inside the insulating bracket 6 without protruding, ensuring that the insulating bracket 6 provides sufficient support for the conductive busbar 2 and improving its installation stability.

[0052] In some embodiments, the inner wall of the busbar trunking 1 is vertically provided with wing plates 7, and multiple wing plates 7 are spaced apart.

[0053] The wing plate 7 is divided into a fixed wing plate 701 and a supporting wing plate 702. The fixed wing plate 701 extends to the surface of the insulating support 6 near the connector 5 and presses the insulating support 6 against the inner wall of the busbar trunking 1. The supporting wing plate 702 is attached to the surface of the insulating support 6 away from the connector 5, so that the insulating support 6 is spaced apart from the inner wall of the busbar trunking 1. The insulating support 6 has fixed wing plates 701 on both the upper and lower sides, and the supporting wing plates 702 are located between adjacent fixed wing plates 701.

[0054] This structural design allows the insulating bracket 6 to be installed and fixed by the upper and lower fixed wing plates 701. At the same time, a heat dissipation channel is formed between the adjacent wing plates 7 on the side of the insulating bracket 6 away from the plug 5, which further increases the number of heat dissipation channels. This ensures that the heat transferred outward from the conductive busbar 2 can still be efficiently dissipated by the heat dissipation channels after passing through the insulating bracket 6.

[0055] In some embodiments, the top of the connector 5 is equipped with a first grounding connector 8 and a second grounding connector 9. An in-slot grounding busbar 10 is mounted on the inner wall of the busbar trunking 1 via an insulating bracket 6, and a housing grounding busbar 11 is integrally formed on the inner wall of the busbar trunking 1. By rotating the connector 5, the end face of the first grounding connector 8 is attached to the in-slot grounding busbar 10, and the end face of the second grounding connector 9 is attached to the housing grounding busbar 11. The in-slot grounding busbar 10 is grounded through a conductor passing through the busbar trunking 1, and the busbar trunking 1 is directly connected to the grounding conductor, thereby grounding the housing grounding busbar 11.

[0056] This structural design allows connector 5 to contact two grounding busbars through two grounding terminals respectively, achieving both casing grounding and busbar grounding within the busbar trough, thus meeting multiple grounding requirements. Furthermore, it forms a dual grounding system, increasing grounding reliability and enhancing the safety of the power distribution system.

[0057] In some embodiments, the first grounding connector 8 and the second grounding connector 9 are symmetrically arranged on the plug connector 5; the in-slot grounding busbar 10 and the housing grounding busbar 11 are symmetrically arranged on the left and right sides in the busbar trunking 1.

[0058] This structural design allows the grounding connectors and grounding busbars to be arranged symmetrically from left to right. By rotating the connector 5 180 degrees, the grounding connector on one side can be switched to the grounding busbar on the other side, realizing the interchangeability of the grounding connectors attached to the grounding busbars on both sides, thereby enabling the switching between two grounding methods and improving the flexibility of use.

[0059] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0060] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
