[0002] The maximum diameter of cables currently used is 11mm, because cables with a diameter larger than this are difficult to bend manually, which greatly limits the design of high-power requirements or increases the complexity of high-power transmission systems, pushing up production and maintenance costs. This solution can fundamentally solve this problem. The strength of cable bending only depends on the thickness and bending strength of the insulation layer, and has nothing to do with the diameter of the conductive metal.

[0003] The utility model divides the conductive metal in the cable into units of specific lengths, and the two ends of each unit are designed to be a matching structure suitable for bending, and mechanical force is used to keep each interface in close contact to control the contact resistance, while ensuring the appropriate degree of freedom of each unit.

[0006] Also included are metal unit two and metal unit three.

[0007] Furthermore, the main body of the second metal unit is a cylinder, and connecting pieces are provided at both ends of the second metal unit. A through hole is provided at the center of the connecting piece, and a pin is provided inside the through hole.

[0008] Furthermore, the connecting piece is composed of a semi-cylinder and a quarter sphere, and the two connecting pieces are located on opposite sides of two ends of the metal unit, and the height of the semi-cylinder and the cross-section of the quarter sphere match each other.

[0009] Furthermore, the main body of the metal unit three is a cylinder, a connecting column is provided at one end of the metal unit three, a sphere is provided at one end of the connecting column, and a claw is provided at the edge of the other end of the metal unit three.

[0010] Furthermore, there are multiple circular arrays of claws, and the sphere can be located inside multiple claws.

[0011] Furthermore, the outer ends of the metal unit 1, the metal unit 2 and the metal unit 3 are provided with an insulating layer, and a metal wire is provided inside the cylindrical hole.

[0012] The advantages of the utility model compared with the existing technology are:

[0013] (1) The utility model divides the conductive metal in the cable into units of specific lengths, and the two ends of each unit are designed to be paired structures suitable for bending. Mechanical force is used to maintain close contact between the interfaces to control the contact resistance, while ensuring the appropriate degree of freedom of each unit.
