[0025] Example 1

[0026] See also Figure 1 The embodiment of the present application provides a ground jumper structure 1000, which is assembled on a return line 2000 and includes: a wire body 1100 and a winding member 1200. Figure 1 and Figure 2The wire body 1100 includes a first connection end 1111 and a second connection end 1121. The first connection end 1111 is connected to the clamping member 3000. The return line 2000 includes a clamping area 2100 and a winding area 2200. The clamping member 3000 is disposed on the clamping area 2100. The winding member 1200 is wound around the winding area 2200 and the second connection end 1121, so that the return line 2000 maintains a first preset angle with the wire body 1100 near the first connection end 1111, and the return line 2000 maintains a second preset angle with the second connection end 1121. On the one hand, the wrapping member 1200 can maintain the stability of the position of the wire body 1100 on the second connecting end 1121, so as to effectively reduce the shaking or swinging of the wire body 1100 on the second connecting end 1121 caused by external force. On the other hand, the wrapping member 1200 cooperates with the clamping member 3000 to fix the wire body 1100 between the first connecting end 1111 and the second connecting end 1121, thereby reducing the reciprocating swing of the wire body 1100 at the end of the clamping member 3000, effectively reducing the bending of the wire body 1100 at the end of the clamping member 3000, reducing the deformation of the wire body 1100 at the end of the clamping member 3000, thereby improving the stability of the position of the wire body 1100, improving the fatigue resistance of the wire body 1100, reducing the risk of breakage of the wire body 1100, and extending the service life of the wire body 1100.

[0027] See also Figure 1 and Figure 2 In some embodiments, the return line 2000 is extended along a first preset direction. The length of the clamping area 2100 along the first preset direction is less than the length of the winding area 2200 along the first preset direction. The winding member 1200 is wound on the winding area 2200 and the second connection end 1121 so that the wire body 1100 between the first connection end 1111 and the second connection end 1121 maintains the first preset direction, thereby maintaining the stability of the position of the wire body 1100 between the first connection end 1111 and the second connection end 1121, reducing the bending of the wire body 1100 at the first connection end 1111, and improving the fatigue resistance of the wire body 1100 at the first connection end 1111, so as to reduce the risk of the wire body 1100 breaking.

[0028] In some embodiments, the clamping member 3000 is a parallel groove wire clamp, and the clamping member 3000 is detachably connected to the clamping area 2100 and the clamping member 3000 is detachably connected to the first connecting end 1111 to facilitate the disassembly and assembly of the clamping member 3000.

[0029] See also Figure 2 In some embodiments, the wire body 1100 includes: a first wire body segment 1110, a second wire body segment 1120, and a third wire body segment 1130. The first connection end 1111 is disposed on the first wire body segment 1110 and is located at the end of the first wire body segment 1110 away from the winding member. A first preset angle exists between the first wire body segment 1110 and the return line 2000. The second connection end 1121 is disposed on the second wire body segment 1120. A second preset angle exists between the second wire body segment 1120 and the return line 2000. The second wire body segment 1120 is connected to the first wire body segment 1110 in an arc transition. One end of the third wire body segment 1130 is connected to the second wire body segment 1120, and the other end of the third wire body segment 1130 is connected to the arm insulator.

[0030] In some embodiments, a second preset angle exists between the second wire segment 1120 and the winding area 2200 .

[0031] In some embodiments, the winding member 1200 is wound on the winding area 2200 and the second wire segment 1120 so that the first wire segment 1110 and the return line 2000 maintain the first preset angle, and the second wire segment 1120 and the winding area 2200 maintain the second preset angle, and the second wire segment 1120 maintains the second preset direction.

[0032] In some embodiments, there is a second preset angle between the second preset direction and the first preset direction, and the second preset angle is less than 90°.

[0033] In some embodiments, the first preset angle is 0° or 180°, that is, the wrapping member 1200 is wrapped around the wrapping area 2200 and the second line segment 1120 so that the first line segment 1110 and the return line 2000 remain parallel.

[0034] In some embodiments, a third preset angle exists between the first line segment 1110 and the second line segment 1120. The third preset angle is greater than the second preset angle, and the sum of the third preset angle and the second preset angle is 180°.

[0035] In some embodiments, the wrapping member 1200 is L-shaped and is a pre-twisted splicing strip. Pre-twisted splicing strips have good elasticity, fatigue resistance, high strength, and can be bent at a preset angle. By wrapping the wrapping member 1200 around the wire body 1100, the impact resistance of the wire body 1100 at the end of the clamping member 3000 can be improved without changing the original positions of the return line 2000, the clamping member 3000, and the arm insulator, thereby improving the fatigue resistance of the wire body 1100 and reducing the risk of wire breakage of the wire body 1100. In addition, the wrapping member 1200 is connected to the wire body 1100 by winding, which is convenient for assembly and disassembly and has high efficiency.

[0036] See also Figure 2 and Figure 3 In some embodiments, the wrapping member 1200 includes a first wrapping portion 1210, a second wrapping portion 1220, and a bending portion 1230. The first wrapping portion 1210 is wrapped around the wrapping area 2200 to form a first sleeve 1240. The second wrapping portion 1220 is wrapped around the second wire segment 1120 to form a second sleeve 1250. The bending portion 1230 connects the first wrapping portion 1210 and the second wrapping portion 1220 to maintain the second preset angle between the first sleeve 1240 and the second sleeve 1250, thereby maintaining the second preset angle between the second wire segment 1120 and the return line 2000, and maintaining the first wire segment 1110 and the return line 2000 in parallel. By cooperating with the clamping member 3000 and the first winding portion 1210, the second winding portion 1220 and the bending portion 1230, the two ends of the first wire segment 1110 can be fixed in position, thereby reducing the movement of the two ends of the first wire segment 1110, effectively improving the fatigue resistance of the first wire segment 1110, and reducing the risk of fatigue breakage of the first wire segment 1110.

[0037] In some embodiments, the shape of the first sleeve 1240 matches the shape of the return line 2000 and is cylindrical. The shape of the second sleeve 1250 matches the shape of the second line segment 1120 and is cylindrical.

[0038] In some embodiments, the bending portion 1230 is located between the return line 2000 and the second line segment 1120 , and the bending portion 1230 is bent in a direction away from the clamping member 3000 .

[0039] The area of the first wire segment 1110 close to the clamping member 3000 is a bending area. When the contact suspension moves longitudinally, the first wire segment 1110 will bend back and forth after being subjected to force, so that the bending area breaks. The present application can fix the relative position of the second wire segment 1120 and the return line 2000 through the cooperation of the first winding part 1210, the second winding part 1220 and the bending part 1230, so that the second wire segment 1120 and the return line 2000 maintain the second preset angle, and can form a rigid support structure for the first wire segment 1110, which can reduce the local stress of the cable and prevent the first wire segment 1110 from being bent and deformed back and forth due to the longitudinal movement of the contact suspension, and can protect the bending area of the first wire segment 1110, thereby improving the fatigue resistance of the wire body 1100, reducing the risk of the wire body 1100 breaking, and effectively extending the life of the wire body 1100.
