[0023] Embodiment:

[0024] AsFigures 1 to 3 The utility model provides a kind of multilayer insulation copper bar, including copper bar body 1, further include: fourth insulating layer 14, third insulating layer 13, second insulating layer 12 and first insulating layer 11 are fixedly sleeved in copper bar body 1 outside in turn, the material quality of first insulating layer 11, second insulating layer 12 and third insulating layer 13 is polyvinyl chloride, polyvinyl chloride is a widely used synthetic plastic, usually used in the manufacture of cable, pipeline, floor, window frame and many other products.It is by vinyl chloride monomer polymerization and becomes macromolecular material, with many significant physical and chemical properties, and therefore is applied in many fields.Fourth insulating layer 14 material quality is glass fiber, glass fiber is a filamentous material made of glass, usually in the form of fiber cloth, yarn or braided into a belt for covering and reinforcing copper bar.And glass fiber has very high tensile strength, can effectively increase the mechanical strength and toughness of copper bar body 1.It can withstand greater tension and impact force, reduce the deformation and damage that may occur in the use process of copper bar body 1.At the same time, glass fiber has excellent high-temperature resistance, can usually withstand 300°C or even higher temperature.Compared with many plastic materials, glass fiber performs more stably in high-temperature environment, and is not easy to soften or deform.This makes it protect copper bar body 1 from damage in high-temperature working environment.In addition, glass fiber is not easily eroded by chemicals, and has strong corrosion resistance.This is a very important advantage for copper bar body 1 that needs to be used in harsh environments (such as acid, alkali, salt water, etc.).Finally, glass fiber itself is a good electrical insulating material, commonly used in the electrical industry as an insulating material.Therefore, as the external coating material of copper bar body 1, glass fiber can provide additional electrical insulation protection to prevent current leakage or short circuit.The multilayer sealing structure of copper bar body 1 can not only improve the electrical insulation performance, but also enhance the mechanical strength and compression resistance of copper rod.The sealing layer usually has strong impact resistance and compression resistance, can prevent the insulation layer from being damaged or deformed due to external force, ensure the stability of the connection and the durability of the overall structure;Sealing connection mechanism is arranged at both ends of copper bar body 1;Locking mechanism is installed at both ends of copper bar body 1 to automatically lock after connecting copper bar body 1.

[0025] Further, the sealing connection mechanism includes a first groove 112, a second groove 122 and a third groove 132 arranged on one end of the copper bar body 1, the first groove 112 is fixedly connected with one end of the first insulating layer 11, the second groove 122 is fixedly connected with one end of the second insulating layer 12, and the third groove 132 is fixedly connected with one end of the third insulating layer 13.

[0026] The first insulating layer 11 has a first convex pad 111 at one end for the first groove 112 to be inserted into, the second insulating layer 12 has a second convex pad 121 at one end for the second groove 122 to be inserted into, and the third insulating layer 13 has a third convex pad 131 at one end for the third groove 132 to be inserted into. The first convex pad 111, the second convex pad 121 and the third convex pad 131 are all made of rubber and are used to achieve multiple sealing connections when inserted into the first groove 112, the second groove 122 and the third groove 132.

[0027] Furthermore, the locking mechanism includes a spiral connecting block 2 fixedly connected to one end of the fourth insulating layer 14 and sleeved on the end of the copper rod body 1. The other end of the fourth insulating layer 14 has a spiral connecting groove 22 that spirally connects to the spiral connecting block 2. A sliding groove 141 is formed inside the spiral connecting groove 22, and a return spring 142 is fixedly connected inside the sliding groove 141. The return spring 142 causes the telescopic block 143 to rotate and pop out. The end of the return spring 142 away from the inner wall of the sliding groove 141 is fixedly connected to the telescopic block 143. The end of the telescopic block 143 away from the return spring 142 is a spherical plug, which ensures that the telescopic block 143 can be quickly and easily inserted into the slot 21. The spiral connecting block 2 has multiple slots 21 arranged in a circumferential array for the end of the telescopic block 143 to engage.

[0028] In this embodiment, when a multi-layered insulating copper rod is required, such as Figure 1 As shown, two identical copper rod bodies 1 are prepared. First, the spiral connecting block 2 at the end of one copper rod body 1 is inserted into the spiral connecting groove 22 at the end of the other copper rod body 1 and rotated. Since the spiral connecting block 2 and the spiral connecting groove 22 are spirally connected, the connecting ends of the pair of copper rod bodies 1 are firmly connected. Then, one copper rod body 1 moves the first insulating layer 11, the second insulating layer 12, the third insulating layer 13, and the fourth insulating layer 14. Immediately afterwards, the first insulating layer 11 moves the first protruding pad 111 into the first groove 112 at the end of the corresponding copper rod body 1, the second insulating layer 12 moves the first groove 112 into the second groove 122 at the end of the corresponding copper rod body 1, and the third insulating layer 13 moves the third protruding pad 131 into the third groove 132 at the end of the corresponding copper rod body 1, thereby making the connecting ends of the pair of copper rod bodies 1 tightly connected. Finally, when the copper rod body 1 and another copper rod body 1 come into contact with each other, the telescopic block 143, through the elastic thrust of the reset spring 142 in the sliding groove 141, causes the end of the telescopic block 143 with the ball plug to be inserted into a random slot 21. At this time, the spiral connecting block 2 cannot rotate in the spiral connecting groove 22, thereby preventing the connecting ends of the pair of copper rod bodies 1 from separating.

The preferred embodiments do not describe all the details and do not limit the utility model to the specific implementation. Obviously, according to the content of the specification, many modifications and changes can be made.
