DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Refer to Figure 1-2The heat-resistant composite braided wire shown includes an inner core 1, an insulating sleeve 2, an outer braided heat-resistant layer 3, a first elastic sleeve 4 and a second elastic sleeve 36. The insulating sleeve 2 is sleeved on the outer side of the inner core 1 and wraps the inner core 1 to form insulation protection for the inner core 1. The outer braided heat-resistant layer 3 is distributed in several groups on the outer side of the insulating sleeve 2 and is braided and sleeved on the surface of the insulating sleeve 2, so as to form an integral structure connected with the inner core 1 through the insulating sleeve 2. The first elastic sleeve 4 is sleeved on the outer side of several braided outer braided heat-resistant layers 3, and the second elastic sleeve 36 is sleeved on the outer side of each outer braided heat-resistant layer 3. The first elastic sleeve 4 has the same structure as the second elastic sleeve 26, but different sizes. They are respectively used to connect and protect the single outer braided heat-resistant layer 3 and the braided parts of several outer braided heat-resistant layers 3, and enhance the overall wear resistance. The first elastic sleeve 4 has a low thickness. It forms an integral structure with the outer braided heat-resistant layer 3 as much as possible.

[0018] The inner core 1 is formed by winding a plurality of copper-aluminum composite wires, and the plurality of copper-aluminum composite wires are spirally intertwined to form the core of the connecting wire for conducting electricity.

[0019] At least 12 groups of outer braided heat-resistant layers 3 are arranged on the outside of the insulating sleeve 2, and multiple groups of outer braided heat-resistant layers 3 are interlaced and woven with each other, so as to protect the inner core 1 as much as possible. The diameter of the inner core 1 and the insulating sleeve 2 is set between 1.5mm-2.5mm, and the diameter of the outer braided heat-resistant layer 3 is between 0.8mm-1.2mm. While forming protection, the loss of material is reduced, and multiple groups are set to enhance the tensile resistance of the outer braided heat-resistant layer 3.

[0020] Each outer braided heat-resistant layer 3 includes at least two glass fiber filaments 31, two chromium-nickel alloy wires 32, two ceramic fiber filaments 33, polytetrafluoroethylene fiber filaments 34 and a core 35 located at the center. The two glass fiber wires, the two chromium-nickel alloy wires 32, the two ceramic fiber filaments 33 and the two polytetrafluoroethylene fiber filaments 34 are symmetrically arranged on the outside of the core 35, and the two glass fiber filaments 31, the two chromium-nickel alloy wires 32, the two ceramic fiber filaments 33 and the two polytetrafluoroethylene fiber filaments 34 are interlaced and woven to fit the core 35. Here, the glass fiber filaments 31, the chromium-nickel alloy wires 32, the ceramic fiber filaments 33 and the polytetrafluoroethylene fiber filaments 34 all have heat-resistant effects. After being woven and entangled together, a multi-layer heat-resistant protection effect is formed to improve the overall heat resistance.

[0021] The wire core 35 and the first insulating sleeve 2 are both made of rubber to form insulation protection. The first elastic sleeve 4 is linearly distributed on the outside of the outer braided heat-resistant layer 3, and the second elastic sleeve 36 is linearly arranged on the outside of the braided heat-resistant layers 3 after being braided. The first elastic sleeve 4 and the second elastic sleeve 36 are both braided with nylon wire and aromatic polyamide fiber wire to improve wear resistance and corrosion resistance. The first elastic sleeve 4 can support the overall structure so that it contacts the object first when in use, so that the overall braided wire is suspended in the air or has less pressure when in contact with the object, so as to improve the protective effect during use.
