[0027] See also Figure 1-4 As shown, the utility model is a two-color polytetrafluoroethylene film mixed type wrapped insulated wire, comprising: a wire core 1, the outer side of the wire core 1 is extruded to form an inner coating layer 2 and an outer coating layer 3 with inner and outer layers;

[0028] The outer side of the wire core 1 is wrapped with a wrapping layer 4, and the outer side of the wrapping layer 4 is provided with a protective pad 5, and the protective pad 5 is used to prevent the wrapping layer 4 from becoming loose after being wrapped;

[0029] The outer side of the protective pad 5 is covered with an outer ring belt 6 for decomposing external forces. Both ends of the outer ring belt 6 are provided with positioning frames 7 for resisting external forces. The outer ring belt 6 and the positioning frames 7 are used to prevent the external forces from being directly transmitted inwards.

[0030] This embodiment provides a wrapping protection mechanism, which can effectively prevent external force from being directly transmitted inward, prevent the wrapping layer 4 from being dislocated, and enable it to maintain high-efficiency performance for a long time. Secondly, its assembly method is simple and can be directly installed on the outside of the wrapping layer 4, which is convenient for batch production operations.

[0031] Among them, the outer side of the protective pad 5 is provided with a protruding ridge 8, and the outer side of the ridge 8 is provided with positioning grooves 12 at equal intervals. After laying, the protective pad 5 is squeezed inwardly, and the rubber mechanism on the inside is used to increase the friction resistance to prevent the wrapping layer 4 from becoming loose and affecting the wrapping effect.

[0032] Among them, reinforcing ribs 9 for guiding external forces are installed near the outer side of the positioning frame 7. The reinforcing ribs 9 are used to conduct the external forces circumferentially to form a force unloading. The circumferential guidance of the external forces by the reinforcing ribs 9 can prevent them from being transmitted linearly inward, so as to achieve the effect of force unloading.

[0033] Among them, an inner ring belt 10 is arranged on the inner side of the outer ring belt 6, and a hollow area is formed between the outer ring belt 6 and the inner ring belt 10 to buffer the external force, so that the external force is isolated outside, forming an effective separation protection.

[0034] Among them, a limiting groove 11 for installing the reinforcing rib 9 is opened near the outer side of the positioning frame 7. The upper end of the limiting groove 11 is a narrow open groove structure. The positioning frame 7 is a rubber structure, and the reinforcing rib 9 can be directly pressed into the interior of the limiting groove 11 when flattened.

[0035] The inner side of the positioning frame 7 is provided with a rubber protrusion 13 which docks with the positioning groove 12 . The rubber protrusion 13 is also used to prevent the outer ring belt 6 from becoming loose during laying.

[0036] The outer ring belt 6 and the positioning frame 7 are in a horizontal plane unfolding state when they are externally rolled up.

[0037] It can be understood that the utility model can protect the wrapping component, so that it can maintain stable performance under the action of external forces, effectively avoid misalignment and looseness, so as to maintain the use effect of the cable.

[0038] A specific application of the operation process of this embodiment is as follows: first, when producing cables, the protective pad 5 is released to the outside of the winding layer 4 through an external winding mechanism, and it is held against to prevent loosening, and then the outer ring belt 6 is released through the external winding mechanism, so that it is wrapped around the outside of the protective pad 5, and the rubber protrusion 13 is connected with the positioning groove 12 to form a positioning, and at the same time, the reinforcing rib 9 is inserted into the inside of the limiting groove 11 through an external pressing mechanism, and finally the released outer ring belt 6 is squeezed and closed by the external annular mechanism to form a wrap. After this arrangement, the positioning frame 7 can transmit the external force to the reinforcing rib 9 when it is subjected to external force, guide it and decompose it, and at the same time, the outer ring belt 6 and the inner ring belt 10 are used to form a buffer, so that the external force cannot be directly transmitted inward, and a force unloading force is formed in the outer layer area to ensure the stable use performance of the inner layer part and improve the service life and effect of the cable.
