Description

Technical Field

[0001] This utility model relates to the field of line installation, and in particular to a copper-aluminum branch connector suitable for multi-branch busbars. Background Technology

[0002] To achieve centralized transmission and unified management of electrical energy and improve the stability and operational efficiency of the power supply system, it is necessary to effectively converge the current from multiple electrical branch lines to a single main line. A scientifically and rationally designed branch line busbar structure not only helps reduce line losses but also significantly improves the operational reliability of the entire electrical system. To achieve reliable busbar connections between multiple branches, copper-aluminum branch connectors suitable for multi-branch busbars are typically used for installation and connection to ensure the safety and stability of circuit operation.

[0003] In related technologies, multi-branch bus connections are mainly made using copper-aluminum branch connectors suitable for multi-branch bus connections. Existing copper-aluminum branch connectors for multi-branch bus connections are connection devices specifically designed for multi-circuit branch bus connections. They integrate multi-input and single-output structures and can connect multiple copper or aluminum wires simultaneously to facilitate centralized current transmission and safe transition. However, when connecting branch lines, they are usually directly connected to the main line. When the branch line is subjected to external force, the connection between it and the main line may easily become loose, thereby affecting the structural stability and operational reliability of the entire bus connection.

[0004] Therefore, it is necessary to provide copper-aluminum branch connectors suitable for multi-branch busbars to solve the above-mentioned technical problems. Utility Model Content

A first connecting hole is formed at both ends of the first rectangular plate. Each connecting bolt passes through the interior of each first connecting hole.

[0010] Preferably, an anti-slip pad is fixedly connected to the side of the clamping block near the threading groove.

[0011] Preferably, the branch threading plate includes a second rectangular plate fixedly connected to one side of the arc-shaped upper shell. The second rectangular plate is located on the upper surface of the first rectangular plate. The lower surface of the second rectangular plate is evenly provided with a plurality of storage slots.

[0012] Compared with related technologies, the copper-aluminum branch connector for multi-branch busbars provided by this utility model has the following advantages:

[0013] 1. This copper-aluminum branch connector, suitable for multi-branch busbars, improves the stability of branch line connections: The mounting shell restricts the installation position of the branch line underplate and the branch line overplate. Multiple branches to be busbars are inserted between the branch line underplate and the branch line overplate, facilitating their integration into the main line installed within the mounting shell. Connecting bolts secure the branch line underplate and the branch line overplate. Operators can control the adjustment bolts to rotate using a screwdriver. Rotation of the adjustment bolts lowers the clamping blocks, clamping and securing the branch lines inserted between the branch line underplate and the branch line overplate. This improves the stability of the branch line connection and minimizes the risk of loosening at the connection point between the branch line and the main line due to external force pulling, ensuring the structural stability and operational reliability of the entire busbar connection.

[0014] 2. This copper-aluminum branch connector, suitable for multi-branch busbars, features an arc-shaped lower shell and an arc-shaped upper shell that close together, allowing the mounting housing to be installed on the main line and protecting the connection between the main line and the branch line. By using connecting bolts to fix the branch through-line plate and the branch through-line plate, the closed position between the arc-shaped lower shell and the arc-shaped upper shell can be limited. Operators can easily check the wiring installation inside the mounting housing through the protective plate installed inside the viewing port.

[0015] 3. This copper-aluminum branch connector, suitable for multi-branch busbars, features a cable-passing groove that allows operators to easily insert branch cables into the first rectangular plate. When the branch cable is clamped by the clamping block, the anti-slip pad increases the friction between the cable and the wire, providing a certain anti-slip effect. The storage groove restricts the installation and movement of the clamping block inside the second rectangular plate. The threaded mounting hole restricts the installation position of the adjusting bolt. The second connecting hole, in conjunction with the first connecting hole and the connecting bolt, limits the connection between the second and first rectangular plates. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 5 A copper-aluminum branch connector suitable for multi-branch busbars includes: a mounting housing 1, a branch through-line plate 2 and a branch through-line plate 3 fixedly connected to one side of the mounting housing 1, the branch through-line plate 2 being located above the branch through-line plate 3, and connecting bolts 4 being provided at both ends of the branch through-line plate 2 and the branch through-line plate 3; multiple clamping blocks 5 being provided, the multiple clamping blocks 5 being evenly and slidably disposed inside the branch through-line plate 3; and multiple adjusting bolts 6 being provided, the multiple adjusting bolts 6 being evenly threadedly connected to the inner wall of the branch through-line plate 3, the lower end face of each adjusting bolt 6 being rotatably connected to the upper surface of each clamping block 5.

[0024] In practical implementation, the mounting shell 1 in this copper-aluminum branch connector suitable for multi-branch busbars is generally made of high-strength insulating engineering plastic or aluminum alloy, with an anti-corrosion insulating coating on the outside. This gives the mounting shell 1 good electrical insulation, corrosion resistance, and mechanical strength, ensuring installation safety and long-term stable operation. The mounting shell 1 is used to install the main line. It also restricts the installation positions of the branch underpass 2 and branch overpass 3. The multiple copper-aluminum conductors to be busbars can be inserted between the branch underpass 2 and branch overpass 3 and then connected to the main line installed in the mounting shell 1. The two ends of the branch underpass 2 and the two ends of the branch overpass 3 are fixed together by connecting bolts 4, thus enabling... The mounting shell 1 serves as a limiting device to prevent it from opening and closing arbitrarily. Furthermore, a clamping block 5 is movably installed inside the branch cable guide plate 3 via an adjusting bolt 6. Multiple sets of clamping blocks 5 are provided in conjunction with the adjusting bolt 6. Specifically, the operator can control the adjusting bolt 6 to rotate using a screwdriver. The rotation of the adjusting bolt 6 allows the clamping block 5 to move up and down inside the branch cable guide plate 3. The downward movement of the clamping block 5 clamps and fixes the branch cable inserted between the branch cable lower plate 2 and the branch cable upper plate 3, thereby improving the stability of the branch cable connection and minimizing the possibility of loosening of the connection between the branch cable and the main line due to external force pulling on the branch cable. This ensures the structural stability and operational reliability of the entire bus connection.

[0025] refer to Figure 1 and Figure 2 As shown, the mounting shell 1 includes an arc-shaped lower shell 101 and an arc-shaped upper shell 102 that are hinged to each other on one side. The side of the arc-shaped lower shell 101 away from the hinged part with the arc-shaped upper shell 102 is fixedly connected to one side of the branch threading plate 2. The side of the arc-shaped upper shell 102 away from the hinged part with the arc-shaped lower shell 101 is fixedly connected to one side of the branch threading plate 3.

[0026] In the specific implementation process, the arc-shaped lower shell 101 and the arc-shaped upper shell 102 can be opened and closed as needed. By closing the arc-shaped lower shell 101 and the arc-shaped upper shell 102, the mounting shell 1 can be installed on the main line. The connection bolt 4 can be used to fix the lower shell 101 and the upper shell 102 between the branch through plate 2 and the branch through plate 3, which can limit the closed position between the arc-shaped lower shell 101 and the upper shell 102.

[0027] refer to Figure 1 and Figure 2 As shown, an inspection port 8 is provided on the arc-shaped upper shell 102, and a protective plate 9 is provided inside the inspection port 8.

[0028] In the specific implementation process, the viewing port 8 can restrict the installation position of the protective plate 9. The protective plate 9 can be made of transparent acrylic sheet so that the operator can see the wiring installation inside the mounting shell 1 through the protective plate 9.

[0029] refer to Figure 2 , Figure 3 and Figure 4 As shown, the branch threading plate 2 includes a first rectangular plate 201 fixedly connected to one side of the arc-shaped lower shell 101. The first rectangular plate 201 is located on the lower surface of the branch threading plate 3. A plurality of threading grooves 202 are evenly provided on the upper surface of the first rectangular plate 201. A first connecting hole 203 is provided at both ends of the first rectangular plate 201. Each connecting bolt 4 passes through the interior of each first connecting hole 203.

[0030] In the specific implementation process, the opening of the wire groove 202 makes it easy for the operator to insert the branch line into the first rectangular plate 201. The opening of the first connecting hole 203 cooperates with the connecting bolt 4 to limit the connection between the first rectangular plate 201 and the branch wire threading plate 3.

[0031] refer to Figure 3 and Figure 5 As shown, an anti-slip pad 7 is fixedly connected to the side of the clamping block 5 near the wire groove 202.

[0032] In the specific implementation process, the anti-slip pad 7 can be made of rubber or silicone with a certain elasticity. When the branch line is clamped by the clamping block 5, the anti-slip pad 7 can increase the friction between the line and the line, thereby achieving a certain anti-slip effect.

[0033] refer to Figure 1 , Figure 2 and Figure 3 As shown, the branch threading plate 3 includes a second rectangular plate 301 fixedly connected to one side of the arc-shaped upper shell 102. The second rectangular plate 301 is located on the upper surface of the first rectangular plate 201. A plurality of storage slots 302 are evenly provided on the lower surface of the second rectangular plate 301. Each storage slot 302 is located above each threading slot 202. Each clamping block 5 is located inside each storage slot 302. A plurality of threaded mounting holes 303 are evenly provided on the upper surface of the second rectangular plate 301. Each threaded mounting hole 303 is connected to each storage slot 302. Each adjusting bolt 6 passes through the interior of each threaded mounting hole 303 and is threadedly connected to it. A second connecting hole 304 is provided at both ends of the second rectangular plate 301. Each second connecting hole 304 is connected to each first connecting hole 203. Each connecting bolt 4 passes through the interior of each second connecting hole 304.

[0034] In the specific implementation process, the storage slot 302 can limit the position of the clamping block 5 installed and moved inside the second rectangular plate 301, the threaded mounting hole 303 can limit the installation position of the adjusting bolt 6, and the second connecting hole 304 can cooperate with the first connecting hole 203 and the connecting bolt 4 to limit the connection between the second rectangular plate 301 and the first rectangular plate 201.

[0035] The working principle of the copper-aluminum branch connector for multi-branch bus provided by this utility model is as follows:

[0036] In use, the branch line under plate 2 and the branch line under plate 3 are installed on one side of the mounting housing 1. The mounting housing 1 is then installed on the main line. Multiple branch lines that need to be combined are threaded between the branch line under plate 2 and the branch line under plate 3, and then connected to the main line installed inside the mounting housing 1. The branch line under plate 2 and the branch line under plate 3 are fixed together by the connecting bolts 4. Multiple clamps 5 are installed one by one inside the branch line under plate 3 by multiple adjusting bolts 6. The operator controls the adjusting bolts 6 to rotate them with a screwdriver. By rotating the adjusting bolts 6, the clamps 5 are moved down to clamp and fix the branch lines threaded between the branch line under plate 2 and the branch line under plate 3. This can improve the stability of the branch line connection and minimize the possibility of the branch line being loosened due to external force pulling on the branch line, so as to ensure the structural stability and operational reliability of the entire bus connection.
