[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. As new energy vehicle manufacturing technology matures, new energy vehicles are gradually entering people's daily lives. In order to better serve new energy vehicles, new energy charging piles are set up in many locations in cities.

[0003] Traditional charging pile wiring harnesses are long, leaving the charging cables hanging loose. This drags the wiring harness along the ground when charging a vehicle, easily causing wear and tear on the wiring harness surface, posing a safety hazard. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide a new energy charging pile wiring harness with safety protection to solve the technical problem that the current charging pile wiring harnesses are all set to be long and the charging cables of the charging piles are always in a scattered state, thereby dragging the charging wiring harness on the ground when charging the vehicle, easily causing the wiring harness surface to wear and break, posing a safety hazard.

[0005] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is as follows: a new energy charging pile wiring harness with safety protection is designed, including a wire body, a plurality of support plates are provided on the outside of the wire body, and the plurality of support plates are equidistantly distributed on the outside of the wire body, and the plurality of support plates are integrated with the wire body;

[0006] One end of each of the support plates is provided with an annular notch, and an annular fixing plate is arranged in each of the annular notches. Multiple semicircular holes are provided at the opposite end of each of the annular fixing plates and the annular notches. The multiple semicircular holes on the annular fixing plates respectively correspond to the multiple semicircular holes on the annular notches, and balls are rotatably connected between the semicircular holes on the annular fixing plates and the semicircular holes on the annular notches.

[0007] Preferably, a fixing bolt is rotatably passed through one end of each of the plurality of annular fixing plates, and the fixing bolt is threadedly connected to the surface of the annular notch.

[0008] Preferably, the wire body includes an outer protective layer, an inner protective layer, a first insulating layer, a shielding layer, a second insulating layer and a wire, and the outer protective layer, inner protective layer, first insulating layer, shielding layer, second insulating layer and wire are connected in sequence from outside to inside.

[0009] Preferably, the outer protective layer is a rubber sleeve, and the inner protective layer is a nylon sheath.

[0010] Preferably, the first insulating layer and the second insulating layer are both made of polyvinyl chloride insulating material.

[0011] Preferably, the shielding layer is composed of tinned copper wire braiding.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model combines structures such as a support plate, a wire body, an annular notch, a semicircular hole, an annular fixing plate and a ball. When the wire body is in use, the support plate supports the wire body and the ball contacts the supporting surface. Therefore, when the wire body is dragged for use, it not only avoids wear and damage caused by direct friction between the wire body and the ground, thereby preventing the risk of electric shock, but also reduces the contact friction between the support plate and the ground, thereby making it easier for people to drag the wire body for use.

[0014] 2. The utility model combines the fixing bolt and the annular fixing plate. By twisting the fixing bolt, the annular fixing plate can be disassembled, thereby facilitating the disassembly and replacement of damaged balls, and further making ball replacement more convenient.

DETAILED DESCRIPTION

[0019] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0020] Example 1: A new energy charging pile wiring harness with safety protection, see Figures 1 to 3, including a wire body 1, a plurality of support plates 2 are provided on the outside of the wire body 1, and the plurality of support plates 2 are equidistantly distributed on the outside of the wire body 1, and the plurality of support plates 2 are integrated with the wire body 1; one end of the plurality of support plates 2 is provided with an annular notch 25, and an annular fixing plate 21 is provided in the plurality of annular notches 25, and the plurality of annular fixing plates 21 and the plurality of annular notches 25 are provided with a plurality of semicircular holes 24 on the opposite end. The plurality of semicircular holes 24 on the annular fixing plate 21 respectively correspond to the plurality of semicircular holes 24 on the plurality of annular notches 25, and a ball 23 is rotatably connected between the semicircular holes 24 on the annular fixing plate 21 and the semicircular holes 24 on the annular notch 25, and a fixing bolt 22 is rotatably passed through one end of the plurality of annular fixing plates 21, and the fixing bolt 22 is rotatably connected to the annular notch The surface of the opening 25 is threadedly connected. When working, the ball 23 is placed in the semicircular hole 24 in the annular notch 25, and then the fixing bolt 22 is twisted to fix the annular fixing plate 21 in the annular notch 25, so that the ball 23 is rotated and connected between the semicircular hole 24 on the annular notch 25 and the semicircular hole 24 on the annular fixing plate 21. When the wire body 1 is in use, the wire body 1 is supported by the support plate 2 and the ball 23 contacts the supporting surface. When the wire body 1 is dragged for use, it not only avoids the wear and damage caused by direct friction with the ground and the risk of electric shock, but also reduces the contact friction between the support plate 2 and the ground, thereby making it easy for people to drag the wire body 1 for use, and the annular fixing plate 21 can be disassembled by twisting the fixing bolt 22, which makes it easy to disassemble and replace the damaged ball 23, and further, it is more convenient to replace the ball 23.

[0021] For details, see Figure 1 and Figure 3 The wire body 1 includes an outer protective layer 16, an inner protective layer 15, a first insulating layer 14, a shielding layer 13, a second insulating layer 12 and a wire 11. The outer protective layer 16, the inner protective layer 15, the first insulating layer 14, the shielding layer 13, the second insulating layer 12 and the wire 11 are connected in sequence from the outside to the inside. The outer protective layer 16 is a rubber sleeve, and the inner protective layer 15 is a nylon sheath. The first insulating layer 14 and the second insulating layer 12 are both made of polyvinyl chloride insulation material. The shielding layer 13 is composed of tinned copper wire. The outer protective layer 16 can increase the strength of the wire body 1, thereby improving the stability of the connection between the support plate 2 and the wire body 1. The inner protective layer 15 can increase the bending and traction ability of the wire body 1. The double-layer insulation of the first insulating layer 14 and the second insulating layer 12 can further improve the insulation effect of the wire body 1. The shielding layer 13 reduces electromagnetic interference on the wire 11, thereby avoiding electromagnetic influence on the charging quality of the vehicle by the wire 11.
