Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4This utility model provides a technical solution: a cable repair patch, comprising a repair patch body 1, an insulation layer 2, reinforcing copper wire pads 3, a closure assembly 4, a temperature-indicating coating 5, a decorative surface layer 6, and a hot melt adhesive layer 7. The insulation layer 2 is provided on the inner wall of the repair patch body 1, and multiple reinforcing copper wire pads 3 are also provided on the outer surface of the repair patch body 1. Each reinforcing copper wire pad 3 includes a protective sheath 31 and reinforcing copper wires 32. The protective sheath 31 wraps around the reinforcing copper wires 32, and the reinforcing copper wires 32 are connected to the closure assembly. Component 4, the surface of the insulating layer 2 is further provided with a decorative surface layer 6, and a hot melt adhesive layer 7 is assembled on the decorative surface layer 6. The closing component 4 includes a perforated groove 41, a closing pad 42, a connecting plate 43, an elastic sheet 44 and a silicone protective pad 45. The closing pad 42 and the connecting plate 43 are respectively set at the left and right ends of the top of the repair patch body 1, and the closing pad 42 is also provided with a perforated groove 41 in the middle. The elastic sheet 44 is fixedly installed on the side of the connecting plate 43, and a layer of silicone protective pad 45 is provided on the outside of the elastic sheet 44.

[0020] As the first embodiment of this utility model: a temperature-indicating coating 5 is added to the left and right ends of the repair patch body 1. This design facilitates monitoring the temperature of the hot melt adhesive layer 7 during baking by setting the temperature-indicating coating 5, preventing damage to the repair patch body 1 due to excessive temperature. The two ends of the reinforcing copper wire 32 are respectively welded to the sides of the closing pad 42 and the connecting plate 43. This design provides an outer layer of protection for the repair patch body 1 by adding the reinforcing copper wire 32, and the reinforcing copper wire 32 can clamp, further increasing the tightness of the repair patch body 1 when fixed. The elastic sheet 44 is made of alloy material, which has good toughness and is not easy to break. The size of the elastic sheet 44 with silicone protective pad 45 is matched with the size of the perforated groove 41 opened on the closing pad 42. This design achieves the clamping and fixing of the repair patch body 1 by using the elastic sheet 44 to pass through the perforated groove 41 opened on the closing pad 42 and then bending it. The structure is simple and convenient. The closing pad 42 and the connecting plate 43 are fixed to the left and right ends of the top of the repair patch body 1 by adhesive. This design helps the repair patch body 1 to be closed and reinforced after repairing the worn cable.

[0021] As a second embodiment of this utility model: After the repair patch body 1 is wrapped around the damaged cable, the hot melt adhesive layer 7 on the inner wall of the repair patch body 1 is attached to the damaged point of the cable. The repair patch body 1 is heated with a heating gun. The hot melt adhesive layer 7 melts when heated and will fill the damaged part of the cable. As the temperature of the temperature-indicating coating 5 on both sides of the repair patch body 1 increases, the temperature-indicating coating 5 changes color. At this time, the heating is stopped. Then, the reinforcing copper wire 32 inside the protective sleeve 31 is pinched by hand. The reinforcing copper wire 32 can be pinched tightly and squeezed to compress the repair patch body 1, so that the closing pad 42 at the top of the repair patch body 1 and the connecting plate 43 are attached. At this time, the elastic piece 44 on the connecting plate 43, with the silicone protective pad 45, passes through the perforated groove 41 on the closing pad 42. After the elastic piece 44 passes through the perforated groove 41, the elastic piece 44 is bent. In this way, the elastic piece 44 will fix the closing pad 42 and the connecting plate 43.
