[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Please refer to the following: Figures 1 to 6To achieve the above objectives, this utility model provides the following technical solution: A fully insulated copper busbar includes a first copper busbar body 1, a second copper busbar body 2, and a third copper busbar body 3; the first copper busbar body 1 and the second copper busbar body 2 are coaxially arranged, wherein a coaxial connection mechanism 4 is provided between the first copper busbar body 1 and the second copper busbar body 2; the second copper busbar body 2 and the third copper busbar body 3 are perpendicular to each other, wherein a right-angle connection mechanism 5 is provided between the second copper busbar body 2 and the third copper busbar body 3.

[0022] Please refer to the following: Figure 1 , Figure 5 As an embodiment of the present utility model, the coaxial connection mechanism 4 includes a first female connector 401 and a first male connector 402. The first male connector 402 is inserted into the first female connector 401 and fixedly connected thereto. The first female connector 401 is fixedly connected to one end of the first copper tube bus body 1. The first male connector 402 is fixedly connected to one end of the second copper tube bus body 2.

[0023] In the above-described scheme, the first female connector 401 is fixedly connected to one end of the first copper busbar body 1 by bolt connection, ensuring good electrical conductivity and mechanical stability between the first female connector 401 and the first copper busbar body 1, so that current can be smoothly transmitted from the first copper busbar body 1 to the first female connector 401; similarly, the first male connector 402 is also fixed to one end of the second copper busbar body 2 by bolt connection; ensuring reliable electrical connection between the first male connector 402 and the second copper busbar body 2, and being able to withstand certain mechanical stress, thus providing a guarantee for the stable operation of the entire connection structure.

[0024] During the connection operation, the first male connector 402 is accurately inserted into the first female connector 401. This process requires ensuring that the insertion direction and angle are accurate to ensure that the two can be correctly connected. After the first male connector 402 is inserted into the first female connector 401, the first copper busbar body 1, the first female connector 401, the first male connector 402, and the second copper busbar body 2 form a continuous electrical path. Current can flow unimpeded from the first copper busbar body 1 through the first female connector 401 and the first male connector 402, and finally to the second copper busbar body 2, ensuring the continuity and stability of power transmission. The coaxial connection mechanism 4 can withstand the mechanical stress that the copper busbar may experience during operation, such as its own weight, wind force, vibration, etc., preventing the copper busbar from shifting or deforming, thereby ensuring the safe and reliable operation of the entire power transmission system.

[0025] Please refer to the following: Figure 2 , Figure 4As an embodiment of this utility model, the first connecting female head 401 includes a connecting seat 4011. A mounting groove 4012 is provided on one side of the connecting seat 4011, wherein a positioning sleeve 4013 is provided in the mounting groove 4012; a conical elastic buckle 4014 is horizontally provided in the inner cavity of the positioning sleeve 4013; one end of the conical elastic buckle 4014 is fixedly connected to the inner wall of the positioning sleeve 4013; a plurality of inclined elastic cards 4015 are provided at equal intervals on the other end of the conical elastic buckle 4014, wherein the movable end of the elastic card 4015 extends toward the bottom of the mounting groove 4012.

[0026] In the above-described scheme, the connector 4011 is fixedly connected to the first copper busbar body 1, realizing the electrical and mechanical connection between the first female connector 401 and the first copper busbar body 1, allowing current to be conducted from the first copper busbar body 1 to the first female connector 401. The mounting groove 4012 on one side of the connector 4011 provides installation space for the positioning sleeve 4013. The size and shape of the connector 4011 are precisely machined according to the design requirements of the positioning sleeve 4013, ensuring that the positioning sleeve 4013 can be securely installed in the mounting groove 4012. The design of the mounting groove 4012 and the positioning sleeve 4013 provides precise guidance and positioning for the first male connector 402, ensuring that the first male connector 402 can be accurately inserted into the first female connector 401, avoiding connection problems or component damage due to insertion deviation. The tapered elastic buckle 4014 is horizontally arranged inside the positioning sleeve 4013, with one end of the tapered elastic buckle 4014 connected to... The positioning sleeve 4013 is fixedly connected to the inner wall, and the other end is a free end with an elastic card 4015. The tapered design of the tapered elastic buckle 4014 allows it to elastically deform when subjected to the insertion force of the first connecting male head 402. The elastic cards 4015 are equidistantly arranged at the other end of the tapered elastic buckle 4014 and are inclined, with the movable end of the elastic card 4015 extending towards the bottom of the mounting groove 4012. When the first connecting male head 402 is inserted, the elastic card 4015 is squeezed and expands outward. When the first connecting male head 402 is inserted into the appropriate position, the elastic card 4015 can return to its original shape, which can lock the first connecting male head 402, so that a stable connection is formed between the first connecting male head 402 and the first connecting female head 401. Even under vibration, external impact, etc., the connection between the first connecting male head 402 and the first connecting female head 401 will not loosen, thereby ensuring the stability and reliability of the electrical connection.

[0027] Please see Figure 4 As one embodiment of the present utility model, a limiting groove 4016 is provided in the middle of the bottom of the mounting groove 4012, wherein the inner diameter of the groove opening of the limiting groove 4016 is larger than the outer diameter of the movable end of the conical elastic buckle 4014.

[0028] In the above-described scheme, the inner cavity of the positioning sleeve 4013 provides the conical elastic buckle 4014 with a space for movement and a positioning reference. Simultaneously, by opening a limiting groove 4016 at the middle of the bottom of the mounting groove 4012, a certain amount of space is provided for the insertion of the first male connector 402 into the first female connector 401. When the first male connector 402 is inserted into the first female connector 401, the front end of the first male connector 402 compresses the conical elastic buckle 4014, causing it to elastically deform. The inner cavity of the positioning sleeve 4013 allows the conical elastic buckle 4014 to... When compressed, it has room to move, avoiding damage due to excessive pressure, thus ensuring the elasticity and service life of the conical elastic buckle 4014. When the first connecting male 402 is inserted into the appropriate position, the conical elastic buckle 4014 will return to its original shape under its own elasticity, and the elastic card 4015 will lock the first connecting male 402. At this time, the limiting groove 4016 plays the role of restricting the first connecting male 402, thereby ensuring that the elastic card 4015 can always maintain a suitable clamping force on the first connecting male 402, preventing the first connecting male 402 from loosening or falling off.

[0029] Please see Figure 4 As one embodiment of the present utility model, the connecting seat 4011 is provided with a connecting contact point 4017 on the side away from the mounting groove 4012, wherein the connecting contact point 4017 is fixedly connected to the first copper tube bus body 1.

[0030] In the above-described scheme, the connecting contact 4017 is typically made of highly conductive materials such as copper or silver. The connecting contact 4017 is fixedly connected to the first copper busbar body 1, ensuring a reliable electrical and mechanical connection between them. This fixed connection prevents the connecting contact 4017 and the first copper busbar body 1 from easily loosening or disconnecting due to external factors (such as vibration or external pulling), providing a stable connection foundation for the entire electrical connection system and ensuring continuous and stable current transmission between them. In the power transmission system, current originates from the power source, is conducted through the first copper busbar body 1 to the connecting contact 4017, and finally reaches the first male connector 402 connected to it, and then to the second copper busbar body 2. The connecting contact 4017, as a key node in the current transmission path, improves the electrical transmission efficiency of the entire system through its connection with the first copper busbar body 1.

[0031] Please refer to the following: Figure 2 , Figure 3 As an embodiment of the present utility model, the first connecting male head 402 includes a plug body 4021, one end of which is fixedly connected to the second copper tube bus body 2, wherein the other end of the plug body 4021 is provided with a tapered boss 4022.

[0032] In the above-described scheme, one end of the plug body 4021 is fixedly connected to the second copper busbar body 2 to ensure that the current can be smoothly transmitted from the second copper busbar body 2 to the plug body 4021. In the power transmission system, the second copper busbar body 2 serves as one of the current transmission channels. Through a reliable connection with the plug body 4021, the current is introduced into the first male connector 402, laying the foundation for the subsequent connection with the first female connector 401 and the further transmission of current. When the first male connector 402 is connected to the first female connector 401, the top of the conical boss 4022 first contacts the entrance of the positioning sleeve 4013 at the front end of the first female connector 401. Due to its conical structure, it can naturally guide the plug body 4021 to gradually insert into the positioning sleeve 4013 in the correct direction. Even if there is a certain insertion deviation, it can be automatically corrected by the guiding effect of the conical surface, improving the accuracy and convenience of insertion and reducing component damage caused by improper insertion. During the insertion process, the conical boss 4022 will engage with the conical elastic buckle 401. 4. The elastic card 4015 interacts with the plug body 4021. As the plug body 4021 is inserted deeper, the conical boss 4022 will squeeze the elastic card 4015 of the conical elastic buckle 4014, causing the elastic card 4015 to open outward. When the conical boss 4022 is inserted into the limiting groove 4016, the elastic card 4015 will return to its original shape under its own elasticity and lock into a specific position of the conical boss 4022, generating a clamping force, thereby firmly connecting the first male connector 402 into the first female connector 401, preventing it from loosening or falling off, and ensuring the reliability of the connection.

[0033] Please refer to the following: Figures 2 to 5 As an embodiment of this utility model, the diameter of the conical boss 4022 is equivalent to the inner diameter of the limiting groove 4016, and the height of the conical boss 4022 is equivalent to the depth of the limiting groove 4016; the plug body 4021 has a mounting hole 4023 in the middle, and a conductive spring pin 4024 is provided in the mounting hole 4023; one end of the conductive spring pin 4024 abuts against the second copper tube bus body 2, and the other end of the top of the conductive spring pin 4024 passes through the conical boss 4022 and abuts against the connecting contact point 4017.

[0034] In the above-described scheme, the diameter of the conical boss 4022 is approximately equal to the inner diameter of the limiting groove 4016, ensuring that the conical boss 4022 can accurately enter the limiting groove 4016 during the insertion of the first male connector 402 into the first female connector 401. The height of the conical boss 4022 is approximately equal to the depth of the limiting groove 4016, ensuring that the conical boss 4022 is fully inserted into the limiting groove 4016 after the first male connector 402 is inserted into the groove. The depth of the limiting groove 4016 restricts the range of movement of the conical boss 4022 in the axial direction, preventing the first male connector 402 from moving excessively in the axial direction when subjected to external forces (such as vibration, tension, etc.), thus ensuring the stability and reliability of the connection between the first male connector 402 and the first female connector 401.

[0035] A mounting hole 4023 is provided in the middle of the plug body 4021 to provide installation space for the conductive spring pin 4024, ensuring that the conductive spring pin 4024 can be smoothly installed and fixed in the plug body 4021, while ensuring that the conductive spring pin 4024 can extend and conduct electricity normally in the mounting hole 4023. The conductive spring pin 4024 is an elastic conductive element. In the first male connector 402, one end of the conductive spring pin 4024 abuts against the second copper tube bus body 2, and the other end passes through the top of the conical boss 4022 and extends outward. This design allows the conductive spring pin 4024 to play a role in buffering and elastic connection when the first male connector 402 is connected to the first female connector 401.

[0036] One end of the conductive spring pin 4024 abuts against the second copper tube bus body 2, realizing the electrical connection between the first male connector 402 and the second copper tube bus body 2. When current is transmitted from the second copper tube bus body 2, it can be smoothly transmitted to the first male connector 402 through the conductive spring pin 4024, providing a channel for subsequent current transmission. The other end of the conductive spring pin 4024 passes through the top of the conical boss 4022 and extends outward. After the first male connector 402 is inserted into the first female connector 401, the top of the conductive spring pin 4024 abuts against the contact point 4017 on the first female connector 401. This abutment method, under the elastic action of the conductive spring pin 4024, can ensure good electrical contact performance, even if some vibration occurs during use. Even with movement or displacement, the conductive spring pin 4024 can automatically adjust through its own elasticity to always maintain close contact with the connection contact point 4017, ensuring that the current can be transmitted stably and reliably between the first male connector 402 and the first female connector 401. The conductive spring pin 4024 connects the second copper tube bus body 2, the first male connector 402, and the connection contact point 4017 of the first female connector 401, forming a complete electrical transmission channel. During the entire connection process, the elastic characteristics of the conductive spring pin 4024 can adapt to the small gaps and displacement changes between different components, effectively reducing the problem of poor electrical contact caused by loose connections, ensuring the continuity and stability of electrical transmission, and improving the reliability and safety of the entire power transmission system.

[0037] Please see Figure 6 As an embodiment of this utility model, the right-angle connection mechanism 5 includes a connector 501; one end of the connector 501 is provided with a second female connector 502, and the other end of the connector 501 is provided with a third female connector 503; the second female connector 502, the third female connector 503 and the first female connector 401 have the same structure and are capable of connecting with the corresponding male connectors. The second female connector 502 and the third female connector 503 are located at both ends of the connector 501, serving as interfaces for current input and output. Through cooperation with the male connectors, electrical connections with other lines or devices are realized; the connector 501 is provided with a fourth copper tube bus body 504, which is set at a right angle, and both ends of the fourth copper tube bus body 504 are fixedly connected to the second female connector 502 and the third female connector 503, respectively.

[0038] In the above-described scheme, the right-angle connection mechanism 5 enables right-angle turns and connections in confined spaces or when a specific route is required, greatly improving the flexibility and space utilization of the line layout and reducing the space occupied by line bends or detours. The second female connector 502 and the third female connector 503 are respectively fixedly installed at both ends of the connector 501, using welding, crimping, or bolt connections to ensure sufficient mechanical strength and electrical connection reliability between the second female connector 502 and the third female connector 503 and the connector 501. To prevent loosening or disconnection during use, the fourth copper busbar body 504 built into connector 501 allows current to change its transmission path along a right angle after entering from the second female connector 502 at one end, and then output from the third female connector 503 at the other end, thereby changing the direction of the line. The fourth copper busbar body 504 has a certain mechanical strength and flexibility, and can withstand certain external forces and environmental factors such as thermal expansion and contraction while maintaining a right angle shape, making it less prone to deformation or damage.

[0039] Please refer to the following: Figure 1 , Figure 6 As one embodiment of the present utility model, the second copper tube bus body 2 is provided with a second connecting male 505 at the end away from the first connecting male 402, wherein the second connecting male 505 is fixedly connected to the second connecting female 502; the third copper tube bus body 3 is provided with a third connecting male 506 at one end, wherein the third connecting male 506 is fixedly connected to the third connecting female 503.

[0040] In the above-described scheme, a second male connector 505 is provided at the end of the second copper busbar body 2 furthest from the first male connector 402. This expands the connection capability of the second copper busbar body 2 beyond its connection function with the first male connector 402, enabling it to connect with other components equipped with second female connectors 502. A third male connector 506 is provided at one end of the third copper busbar body 3, providing an interface for its connection and allowing it to be integrated into the entire electrical connection system, enabling power interaction with other lines or equipment. By providing the second male connector 505 and the third male connector 506, the electrical connection system gains greater flexibility and scalability. According to actual needs, the second copper busbar body 2 and the third copper busbar body 3 can be connected with other components equipped with corresponding female connectors to achieve line extension, branching, or complex connections between equipment, meeting different electrical layout and functional requirements.
