[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a split flexible thermal connector, including a connector body 1. Symmetrical through grooves 2 are provided at both ends of the connector body 1. Symmetrical fixing grooves 6 are provided at the edges of the through grooves 2. Symmetrical sliding grooves 3 are provided on the inner walls of both sides of the through grooves 2. A connecting structure is also provided inside the through grooves 2. The connecting structure includes a connecting block 4 installed inside the through grooves 2. Symmetrical protrusions 5 are provided at both ends of the connecting block 4. One end of the protrusion 5 is slidably installed in the sliding grooves 3 opened on the inner walls of both sides of the through grooves 2.

[0024] refer to Figure 2 and Figure 3 The top of the protrusion 5 has a fixing hole, which corresponds to the fixing groove 6 and is fixed by fixing bolts 7 and clamping plates. The connecting block 4 has a connecting hole 8, and a sealing protrusion 9 is provided on the top of the connecting block 4 at the edge of the connecting hole 8. A rubber connecting strip 10 is also provided on the top of the connecting block 4 near one side edge. One end of the rubber connecting strip 10 is connected to a sealing block 11, which is compatible with the sealing protrusion 9. More specifically, when connecting batteries of different specifications, by moving the connecting block 4, the two ends of the sealing protrusion 9 can be aligned. The protrusion 5 slides along the groove 3, allowing the connecting block 4 to move left and right to adjust its position. Then, the fixing bolt 7 passes through the fixing groove 6 and the fixing hole on the protrusion 5. By tightening the fixing bolt 7, the clamping plate is pressed against the top of the fixing groove 6, thus fixing the position of the connecting block 4. This makes it easier for staff to connect batteries of different specifications, improving practicality. After connection, by pressing the sealing plug 11 connected to one end of the rubber connecting strip, it is matched with the sealing protrusion 9, thereby sealing the connection and providing a waterproof function.

[0025] refer to Figure 4A multi-layered composite flexible structure is provided at the middle section of the connector body 1. This multi-layered composite flexible structure includes a high thermal conductivity layer 12, an insulating layer 13, and a wear-resistant layer 14. The high thermal conductivity layer 12 is located in the innermost layer and is made of high thermal conductivity copper foil with a thickness between 10-50 μm. The insulating layer 13 is located in the middle layer and is made of flexible insulating polyimide film with a thickness between 25-100 μm. The wear-resistant layer 14 is located in the outermost layer and is made of highly flexible and wear-resistant silicone rubber with a thickness between 0.5-2 mm. More specifically, by providing a multi-layered composite flexible structure at the middle section of the connector body 1... The high thermal conductivity layer 12, the insulating layer 13, and the wear-resistant layer 14 are all included. The high thermal conductivity layer 12 is made of copper foil, a metal material with high thermal conductivity, which can quickly transfer the heat generated by the battery. The insulating layer 13 is made of polyimide film, a flexible insulating material, which can effectively prevent electrical short circuits between different components. The wear-resistant layer 14 is made of silicone rubber with high flexibility and wear resistance, which can adapt to various complex bending and stretching deformations and has good wear resistance. Through the multi-layer composite structure, the connector can not only conduct heat efficiently, but also effectively avoid electrical short circuits, while maintaining good flexibility and mechanical properties in various complex operating environments.

[0026] The implementation principle of a split flexible thermal connector according to an embodiment of this application is as follows: In use, by moving the connecting block 4, the two end protrusions 5 slide along the sliding groove 3, allowing the connecting block 4 to move left and right to adjust its position. Then, the fixing bolt 7 fixes the position of the connecting block 4, thereby facilitating the connection of batteries of different specifications by the staff and improving practicality. At the same time, the cooperation between the sealing block 11 and the sealing protrusion 9 can play a waterproof role at the connection. By setting a high thermal conductivity layer 12, an insulating layer 13 and a wear-resistant layer 14 in the middle section of the connector body 1, when the connector body 1 is in use, the high thermal conductivity copper foil in the high thermal conductivity layer 12 can quickly transfer the heat generated by the battery. The flexible insulating polyimide film in the insulating layer 13 can effectively prevent electrical short circuits between different components. The highly flexible and wear-resistant silicone rubber in the wear-resistant layer 14 can adapt to various complex bending and stretching deformations and has good wear resistance. Through the multi-layer composite structure, the connector can not only efficiently conduct heat but also effectively avoid electrical short circuits, while maintaining good flexibility and mechanical properties in various complex usage environments.
