Description

Technical Field

[0001] This utility model relates to the technical field of copper busbar connectors, specifically a copper busbar connector. Background Technology

[0002] Copper busbar connectors are key components in electrical systems that enable mechanical fixing and conductive connections between copper busbars and between copper busbars and electrical equipment. Their core function is to create a low-resistance conductive path using highly conductive materials, while simultaneously withstanding mechanical stress to prevent loosening. They are primarily fixed using bolts, clips, and welding, and must be compatible with different copper busbar specifications and installation scenarios. Common types include bolt-type, plug-in, and custom-made parts. They are widely used in high and low voltage power distribution, new energy, industrial automation, and other high-voltage circuits, serving as a fundamental component for ensuring the safe and efficient operation of electrical systems.

[0003] Traditional copper busbar connectors are integrally designed with a fixed length. When making flexible connections, different models of copper busbar connectors need to be customized according to the actual situation. This means that different copper busbars require customized connectors to achieve a connection. When the specifications of the connected object change, the original connectors are no longer compatible with the new connection requirements and need to be re-customized to achieve an effective connection. This results in extremely poor versatility of the connectors, which not only increases the cost of use but also may delay the construction progress in emergency repair scenarios due to model incompatibility. To address this, we propose a copper busbar connector. Utility Model Content

[0004] The main purpose of this utility model is to provide a copper busbar connector that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a copper busbar connector, comprising a first connecting plate and a second connecting plate, wherein a plug strip is fixedly connected to one side of the first connecting plate, and a plug groove is provided in the inner cavity of the second connecting plate, the plug groove being adapted to the plug strip and extending transversely through the second connecting plate, a fastening component is provided on the side of the plug strip opposite to the first connecting plate, and a connecting end is fixedly connected to the opposite side of both the first and second connecting plates, and a heat dissipation structure for automatically accelerating heat dissipation is provided on the surface of the plug strip and the surface of the second connecting plate.

[0006] Preferably, the heat dissipation structure includes a ventilation groove and a snap-fit ​​groove. The upper surface of the snap-fit ​​strip has ventilation grooves on both sides, and the upper surface of the second connecting plate has a snap-fit ​​groove that penetrates the upper surface of the second connecting plate and communicates with the snap-fit ​​groove.

[0007] Preferably, the surface of the connector strip is coated with a graphene thermal conductive paste layer.

[0008] Preferably, the fastening assembly includes a nesting hole, a fastening bolt, and a fastening nut. The insertion slot has a nesting hole vertically opened on one side relative to the first connecting plate. The fastening bolt is detachably nested in the inner cavity of the nesting hole. The end of the fastening bolt passes through the snap-fit ​​groove and extends to the outside of the second connecting plate. A fastening nut is threaded onto the surface of the fastening bolt above the snap-fit ​​groove.

[0009] Preferably, the inner wall of the fastening nut is provided with an elastic washer, and the inner side of the elastic washer abuts against the bottom end of the inner cavity of the inner wall of the snap-fit ​​groove.

[0010] Preferably, each of the connecting ends has a connecting hole on its surface.

[0011] Preferably, the first connecting plate, the second connecting plate, and the plug strip are all made of copper.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention achieves adjustable length of the copper busbar connector composed of the first and second connecting plates through the cooperation of a copper plug strip on one side of the first connecting plate, a snap-fit ​​groove inside the second connecting plate, and a fixing structure of fastening bolts and nuts. This allows for length adjustment according to requirements, effectively improving connection flexibility and versatility. Within a certain range, it eliminates the need for custom-made connectors for different connection distances, reducing spare parts types, lowering inventory costs and management complexity.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example

[0020] Please see Figure 1 - Figure 3 The copper busbar connector shown in the figure includes a first connecting plate 1 and a second connecting plate 2. A plug strip 3 is fixedly connected to one side of the first connecting plate 1. A plug groove 4 is provided in the inner cavity of the second connecting plate 2, and the plug groove 4 is adapted to the plug strip 3 and extends horizontally through the second connecting plate 2. A fastening component 5 is provided on the side of the plug strip 3 opposite to the first connecting plate 1. A connecting end 6 is fixedly connected to the opposite side of the first connecting plate 1 and the second connecting plate 2. The surfaces of the plug strip and the second connecting plate 2 are provided with heat dissipation structures for automatically accelerating heat dissipation. By cooperating with the plug strip 3 of the first connecting plate 1 and the through-hole plug groove 4 of the second connecting plate 2, and with the fastening component, the length can be flexibly adjusted according to the needs during use, without the need to customize special parts for different connection distances, effectively improving the versatility and adaptability of use.

[0021] The heat dissipation structure includes a ventilation groove 9 and a snap-fit ​​groove 10. Ventilation grooves 9 are laterally formed on both sides of the upper surface of the plug strip 3. The snap-fit ​​groove 10 is formed on the upper surface of the second connecting plate 2 and penetrates through the upper surface of the second connecting plate 2 and communicates with the plug groove 4. A graphene thermal conductive paste layer 11 is coated on the surface of the plug strip 3. The ventilation grooves 9 on the upper surface of the plug strip 3 and the snap-fit ​​groove 10 of the second connecting plate 2 are interconnected, forming an efficient air convection channel to accelerate the dissipation of heat at the plug joint. The graphene thermal conductive paste layer 11 coated on the surface of the plug strip 3 can enhance the heat conduction efficiency of the contact surface between the plug strip 3 and the plug groove 4. The two work together to effectively improve the heat dissipation performance of the copper busbar connector, effectively avoid the decrease in conductivity due to overheating, and effectively ensure its stability in long-term use.

[0022] The fastening assembly 5 includes a nesting hole 8, a fastening bolt 501, and a fastening bolt 501. The insertion groove 4 has a nesting hole 8 vertically opened on one side relative to the first connecting plate 1. The fastening bolt 501 is detachably nested in the inner cavity of the nesting hole 8. The end of the fastening bolt 501 passes through the snap-fit ​​groove 10 and extends to the outside of the second connecting plate 2. A fastening nut 502 is threadedly connected to the surface of the fastening bolt 501 at the top of the snap-fit ​​adjustment. An elastic washer 503 is provided on the inner wall of the fastening nut 502, and the inner side of the elastic washer 503 abuts against the bottom end of the inner wall cavity of the snap-fit ​​groove 10. The fastening bolt 501 and the fastening nut 502 facilitate the quick fixing of the insertion strip 3 to the second connecting plate 2. The elastic washer 503 on the inner wall of the fastening nut 502 abuts against the bottom end of the inner wall cavity of the snap-fit ​​groove 10, which can effectively buffer vibration, compensate for gaps, prevent loosening during long-term use, and ensure the stability and reliability of the connection.

[0023] The connecting end 6 has connecting holes 7 on its surface. The first connecting plate 1, the second connecting plate 2, and the plug strip 3 are all made of copper. The connecting holes 7 on the surface of the connecting end 6 facilitate quick docking and installation with external copper busbars or equipment. The copper structure of the first connecting plate 1, the second connecting plate 2, and the plug strip 3 ensures excellent conductivity, enhances the mechanical strength and corrosion resistance of the overall structure, and improves the compatibility and service life of the connector.

[0024] It should be noted that this utility model is a copper busbar connector. During installation, according to the actual connection distance, the fastening bolt 501 is inserted into the nesting hole 8 on the side of the insertion groove 4 opposite to the first connecting plate 1, so that the end of the fastening bolt 501 passes through the snap-fit ​​groove 10 on the upper surface of the second connecting plate 2 and extends to the outside. Then, the insertion strip 3 on the side of the first connecting plate 1 is inserted into the insertion groove 4 in the inner cavity of the second connecting plate 2, and the bolt slides along the snap-fit ​​groove 10. The required connection size is adapted by adjusting the length of the insertion strip 3 extending into the insertion groove 4. Then, the fastening nut 502 is tightened on the surface of the fastening bolt 501 above the snap-fit ​​groove 10 until the elastic washer 503 on the inner side wall of the fastening nut 502 is in contact with the snap-fit ​​groove. The inner wall of the 10 is tightly abutted to the bottom, thus fixing the plug strip 3 to the second connecting plate 2. Then, using the connecting holes 7 on the connecting ends 6 on the opposite side of the first connecting plate 1 and the second connecting plate 2, the copper busbar connector is docked and fixed to the external copper busbar or equipment, thus completing the installation. During use, the ventilation grooves 9 on both sides of the upper surface of the plug strip 3 and the snap-fit ​​grooves 10 of the second connecting plate 2 form a connected heat dissipation channel, thereby achieving ventilation and heat dissipation. Combined with the graphene thermal conductive paste layer 11 coated on the surface of the plug strip 3, the heat dissipation effect is automatically accelerated, ensuring that the copper busbar connector maintains good heat dissipation performance and electrical conductivity stability during use, effectively reducing the limitations of use while improving the practical effect.
