Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a compression-resistant component of a charging cable for a new energy vehicle. Background Art

[0002] Nowadays, new energy vehicles are widely used. New energy vehicles use electricity as energy, which can effectively reduce pollution to the environment. However, new energy vehicles need to be equipped with charging piles for charging. In the existing technology, when new energy vehicles are charged, fires often occur due to the long charging time. Therefore, the charging cable used must have good high temperature resistance and fire resistance, and the charging cable must also have good pressure resistance due to the coming and going of vehicles in the charging area.

[0003] A pressure-resistant, high-temperature-resistant, and easy-to-dissipate heat dissipation new energy vehicle charging cable with Chinese patent application number CN202111618322.9 includes a plurality of charging units and two pressure-resistant skeletons. The two pressure-resistant skeletons are arranged as semi-elliptical structures for use together, and the butt joint end faces of the two pressure-resistant skeletons are provided with unit grooves adapted to the size of the charging units. The two pressure-resistant skeletons can be butt jointed into an overall elliptical structure. However, when the cable is in use, the cable will be damaged when the wheels repeatedly pass by.

[0004] A cable for new energy vehicles with Chinese patent application number CN202010651896.5 includes a cable body, the cable body includes a cable core and a cable core protective sleeve covered on the surface of the cable core, the cable core protective sleeve includes a water-blocking wrapping layer, a shielding layer, an inner protective layer and an outer protective layer from the inside to the outside, and the cable core includes a buffering special-shaped bracket with a "Y"-shaped cross-section. However, when the device is in use, when the cable crosses the road, the cable is easily crushed and damaged by passing vehicles.

[0005] During the application of the cable body in the field of new energy vehicles, when installing charging piles, the cable body will pass through the community road. It is time-consuming and labor-intensive to dig grooves in the road to bury the cable body, and the dug grooves need to be re-paved with cement and wait for solidification before normal driving. When the cable body is placed directly on the road, the cable body will be damaged as the vehicle passes by, affecting the use of the cable body. Therefore, it is necessary to set a pressure-resistant component on the cable body so that when the cable body crosses the road, the cable body can be protected with the assistance of the pressure-resistant component. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a pressure-resistant component for a new energy vehicle charging cable.

[0007] The present invention provides a pressure-resistant assembly of a new energy vehicle charging cable, comprising a pressure-resistant portion and a cable body, wherein the cable body passes through the pressure-resistant portion;

[0008] The pressure-resistant part includes a pressure-resistant shell, a first cavity is arranged in the pressure-resistant shell, a wire rack is arranged in the first cavity, the cable body passes through the wire rack, the wire rack is elastic, a pressure sensor is arranged on the surface of the pressure-resistant shell, a second cavity is arranged on both sides of the first cavity in the pressure-resistant shell, a third cavity is arranged on the top of the first cavity in the pressure-resistant shell, connecting pipes are arranged between the first cavity and the second cavity and the third cavity, and a pressure valve is arranged in the connecting pipes.

[0009] By setting the first cavity, the second cavity, the third cavity, the pressure sensor, the electronically controlled two-way hydraulic cylinder and the lifting hydraulic cylinder and other components, the pressure of the wheel against the pressure shell can be detected with the assistance of the pressure sensor, and the electronically controlled two-way hydraulic cylinder and the lifting hydraulic cylinder and other components can be adjusted accordingly according to different pressures. When the detection value of the pressure sensor reaches the first threshold value, the pressure of the non-Newtonian fluid in the second cavity and the third cavity increases, which causes the pressure valve to open, and then slowly releases the pressure to buffer the pressure of the wheel. When the detection value of the pressure sensor is between the first threshold value and the second threshold value, the lifting hydraulic cylinder is used to move the wire rack downward, and the non-Newtonian fluid in the first cavity will gather above the wire rack to strengthen the protection of the wire rack. When the detection value of the pressure sensor reaches the second threshold value, By controlling the electronically controlled bidirectional hydraulic cylinder, the push plate is moved, and the non-Newtonian fluid in the first cavity is pushed to both sides, so that the first cavity generates a reaction force at the wheel, so as to better protect the opposing wire rack. When the detection value of the pressure sensor exceeds the second threshold value, the first cavity, the second cavity and the third cavity will be squeezed, and the non-Newtonian fluid in the second cavity will enter the limiting hole. The pressure of the non-Newtonian fluid in the limiting hole acts on the first fitting plate. With the cooperation of the first fitting plate and the second fitting plate, the second fitting plate is disengaged from the slot, and the pressure-resistant shell is moved downward. The friction between the support plate and the support plate will play a buffering role. When the pressure-resistant shell descends and retracts into the mounting base, the pressure-resistant shell can be better protected, ensuring that the cable body can be used stably.

[0010] Preferably, an electrically controlled bidirectional hydraulic cylinder is provided at the upper end of the inner wall of the first cavity, and the electrically controlled bidirectional hydraulic cylinder is arranged at the upper end of the wire rack. An output rod is provided at the output end of the electrically controlled bidirectional hydraulic cylinder, and a push plate is provided at the end of the output rod, and the top of the push plate matches the inner wall of the first cavity.

[0016] Preferably, non-Newtonian fluid is arranged in the first cavity, the second cavity and the third cavity.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting the first cavity, the second cavity, the third cavity, the pressure sensor, the electronically controlled two-way hydraulic cylinder, the lifting hydraulic cylinder and other components, the pressure of the wheel on the anti-pressure shell can be detected with the assistance of the pressure sensor, and the electronically controlled two-way hydraulic cylinder and the lifting hydraulic cylinder and other components are adjusted accordingly according to different pressures. When the detection value of the pressure sensor reaches the first threshold, the pressure of the non-Newtonian fluid in the second cavity and the third cavity increases, causing the pressure valve to open, and then slowly releases the pressure to buffer the pressure of the wheel.

[0019] 2. By setting the first cavity, the second cavity, the third cavity, the pressure sensor, the electronically controlled two-way hydraulic cylinder, the lifting hydraulic cylinder and other components, the pressure of the wheel on the anti-pressure shell can be detected with the assistance of the pressure sensor, and the electronically controlled two-way hydraulic cylinder and the lifting hydraulic cylinder and other components can be adjusted accordingly according to different pressures. When the detection value of the pressure sensor is between the first threshold value and the second threshold value, the lifting hydraulic cylinder is used to move the wire rack downward, and the non-Newtonian fluid in the first cavity will gather above the wire rack to strengthen the protection of the wire rack.

[0020] 3. By setting the first cavity, the second cavity, the third cavity, the pressure sensor, the electronically controlled two-way hydraulic cylinder and the lifting hydraulic cylinder and other components, the pressure of the wheel on the anti-pressure shell can be detected with the assistance of the pressure sensor, and the electronically controlled two-way hydraulic cylinder and the lifting hydraulic cylinder and other components can be adjusted accordingly according to different pressures. When the detection value of the pressure sensor exceeds the second threshold value, the first cavity, the second cavity and the third cavity will be squeezed, and the non-Newtonian fluid in the second cavity will enter the limiting hole. The pressure of the non-Newtonian fluid in the limiting hole acts on the first fitting plate. With the cooperation of the first fitting plate and the second fitting plate, the second fitting plate is detached from the slot, thereby moving the anti-pressure shell downward. The friction between the support plate and the support plate will play a buffering role. When the anti-pressure shell descends and retracts into the mounting base, the anti-pressure shell can be better protected to ensure that the cable body can be used stably.

[0031] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive. Embodiment 1

[0032] like Figure 1 to Figure 2As shown, the present embodiment discloses a new energy vehicle charging cable, including a cable body 1, the cable body 1 includes a core 101, the core 101 is provided with four, an aluminum sheath 102 is provided on the outside of the core 101, a protective layer 103 is provided on the outside of the aluminum sheath 102, an insulating layer 104 is wrapped on the outside of the protective layer 103, a waterproof layer 105 is provided on the outside of the four insulating layers 104, an insulating filler 106 is filled between the waterproof layer 105 and the insulating layer 104, a wear-resistant layer 107 is provided on the outside of the waterproof layer 105, a fireproof material tube 108 is provided in the insulating filler 106, a fire extinguishing liquid is provided in the fireproof material tube 108, a connecting wire 109 is provided in the center of the insulating filler 106, the four cores 101 correspond to each other, and the core 101 can be protected with the aid of the aluminum sheath 102 to avoid the cable body 1 being made During the operation, the wires of the core 101 are scattered. The core 101 can be further protected with the assistance of the protective layer 103, and there is an insulating layer 104 on the outside of the protective layer 103. The insulating layer 104 can prevent the four cores 101 from conducting each other and causing accidents. When a large current passes through the core 101, the core 101 will generate heat. Once a fire occurs, the fireproof material tube 108 at the burning part of the cable body 1 will rupture, and the fire extinguishing liquid in the fireproof material tube 108 will assist in extinguishing the fire. When the cable body 1 is moving and stretching, if a force is directly applied to the core 101, it is easy to cause damage to the core 101. When moving and stretching with the assistance of the connecting wire 109, the damage to the core 101 can be reduced, and the connecting wire 109 is made of steel wire, which has a stable structure and good tensile performance.

[0033] The wear-resistant layer 107 is made of a nylon tube, thereby increasing the wear resistance of the cable body 1 and making the cable body 1 more stable during use.

[0034] During use, the connecting wire 109 is provided to effectively improve the tensile strength of the cable and prevent the cable body 1 from being broken. The insulating filler 106 is provided to make the cable body 1 have insulating properties, so that each core 101 is independent of each other. With the assistance of the wear-resistant layer 107, the cable body 1 can be effectively prevented from being worn. With the assistance of the waterproof layer 105, rainwater can be effectively prevented from contacting the core 101. In addition, the aluminum sheath 102, the fireproof material tube 108 and the insulating layer 104 can effectively improve the fireproof performance of the cable body 1, and can effectively prevent the cable body 1 from being burned or short-circuited in a high temperature and fire environment. Embodiment 2

[0035] During the application of the cable body 1 in the field of new energy vehicles, when installing the charging pile, the cable body 1 will pass through the community road. It is time-consuming and labor-intensive to dig grooves in the road to bury the cable body 1, and the dug grooves need to be re-paved with cement and wait for solidification before normal driving. When the cable body 1 is directly placed on the road, the cable body 1 will be damaged as the vehicle passes by, affecting the use of the cable body 1. Therefore, it is necessary to set a pressure-resistant component on the cable body 1 so that when the cable body 1 crosses the road, the cable body 1 can be protected with the assistance of the pressure-resistant component.

[0036] like Figures 1 to 9 As shown, this embodiment also discloses a pressure-resistant component of a new energy vehicle charging cable, including a pressure-resistant part 2, through which the cable body 1 passes. When the cable body 1 needs to be laid across a community road, the cable body 1 is first passed through the pressure-resistant part 2, and then a groove is opened in the road, so that the pressure-resistant part 2 is installed in the groove opened in the road.

[0037] The pressure-resistant part 2 includes a pressure-resistant shell 201, a first cavity 202 is provided in the pressure-resistant shell 201, a wire rack 203 is provided in the first cavity 202, the cable body 1 passes through the wire rack 203, the wire rack 203 has elasticity, a second cavity 204 is provided on both sides of the first cavity 202 in the pressure-resistant shell 201, a third cavity 205 is provided on the top of the first cavity 202 in the pressure-resistant shell 201, and the first cavity 202 and the second cavity 204 and A connecting pipe 206 is provided between the third cavities 205, and a pressure valve is provided in the connecting pipe 206. Non-Newtonian fluid is provided in the first cavity 202, the second cavity 204 and the third cavity 205. The cable body 1 passes through the wire rack 203, and the wire rack 203 is elastic and located in the first cavity 202. When the vehicle passes through the pressure-resistant part 2, the wheel will first press on one side of the pressure-resistant shell 201, and then the wheel will move to the top of the pressure-resistant shell 201. And it drives out from the other side of the pressure-resistant shell 201. Therefore, in the process of the wheel passing through the pressure-resistant shell 201, the second cavity 204 is squeezed first, and then the third cavity 205 on the top is squeezed, and finally, the second cavity 204 on the other side is squeezed. In this process, when the squeezing of the third cavity 205 and the second cavity 204 is too large, the pressure valve will be opened, and then the non-Newtonian fluid in the third cavity 205 and the second cavity 204 will be discharged into the first cavity 202 through the connecting pipe 206 for slow pressure relief, so as to have a buffering effect, which is beneficial to protect the anti-pressure part 2. Since the non-Newtonian fluid is arranged in the first cavity 202, the second cavity 204 and the third cavity 205, when the speed of the passing vehicle is too fast, the physical properties of the non-Newtonian fluid can protect the anti-pressure part 2, so that the cable body 1 is well protected in the anti-pressure part 2, so that it can be used stably.

[0038] A pressure sensor is provided on the surface of the pressure-resistant shell 201, and the pressure of the vehicle when it is running can be detected with the assistance of the pressure sensor.

[0039] An electrically controlled bidirectional hydraulic cylinder 207 is provided at the upper end of the inner wall of the first cavity 202, and the electrically controlled bidirectional hydraulic cylinder 207 is provided at the upper end of the wire rack 203. An output rod 208 is provided at the output end of the electrically controlled bidirectional hydraulic cylinder 207, and a push plate 209 is provided at the end of the output rod 208. The top of the push plate 209 matches the inner wall of the first cavity 202. When the pressure sensor detects that the pressure when the wheel crosses the pressure-resistant shell 201 is too large, the electrically controlled bidirectional hydraulic cylinder 207 is started, and the output end of the electrically controlled bidirectional hydraulic cylinder 207 drives the output rod 208 to extend, thereby moving the push plate 209. When the push plate 209 moves, it pushes the non-Newtonian fluid in the first cavity 202 to both sides, thereby increasing the non-Newtonian fluid in the first cavity 202 corresponding to the wheel, so that the first cavity 202 generates a reaction force at the wheel, so as to better protect the wire rack 203 and reduce the pressure on the cable body 1 in the wire rack 203.

[0040] A lifting hydraulic cylinder 213 is provided at the bottom end of the pressure-resistant shell 201, and the output end of the lifting hydraulic cylinder 213 is inserted into the first cavity 202. A connecting plate 214 is provided at the output end of the lifting hydraulic cylinder 213, and the connecting plate 214 is arranged at the lower end of the wire rack 203. When the wheel passes through the pressure-resistant shell 201 and generates downward pressure, it is detected by the pressure sensor, and then the lifting hydraulic cylinder 213 is controlled to start, so that the connecting plate 214 moves downward, and then the wire rack 203 moves downward. When the wire rack 203 moves downward, the non-Newtonian fluid in the first cavity 202 will be more gathered at the upper end of the wire rack 203 to avoid the deformation of the upper pressure-resistant shell 201 squeezing the wire rack 203, and more non-Newtonian fluid gathers at the upper end of the wire rack 203, which can also achieve a better buffering effect.

[0041] The inner side of the push plate 209 matches and fits with the wire rack 203, and a first limit groove 210 is provided at the lower end of the push plate 209. A limit plate 211 is provided in the first limit groove 210, and a spring 212 is provided between the limit plate 211 and the push plate 209. The lower end of the limit plate 211 matches and fits with the wire rack 203. When the wire rack 203 moves downward, due to the assistance of the spring 212, the limit plate 211 will always fit the surface of the wire rack 203, thereby ensuring that the push plate 209 can push the non-Newtonian fluid when it moves horizontally.

[0042] A mounting base 215 is provided at the lower end of the pressure-resistant shell 201, and a support plate 216 is provided on the mounting base 215. A support plate 217 is provided at the lower end of the pressure-resistant shell 201. A limiting hole 218 is provided on the support plate 217, and the limiting hole 218 is communicated with the second cavity 204. A first engaging plate 219 is slidably provided in the limiting hole 218, and a second limiting groove 220 is provided at the lower end of the limiting hole 218 in the support plate 217. A second engaging plate 221 is slidably provided in the second limiting groove 220, and a damping cylinder 222 is provided between the second engaging plate 221 and the side wall of the second limiting groove 220. A slot 223 is provided on one side of the support plate 216 close to the support plate 217, and the second engaging plate 221 is inserted into the slot 223. The first engaging plate 219 and the second engaging plate 221 are wedge-shaped matched. When a vehicle passes through the pressure-resistant part 2, if the weight of the vehicle is too large, the pressure According to the detection value of the sensor, when the pressure-resistant part 2 cannot bear the weight of the vehicle, when the vehicle passes directly above the pressure-resistant part 2, the pressure in the second cavity 204 will increase, and then the pressure of the non-Newtonian fluid in the second cavity 204 will act on the first fitting plate 219, causing the first fitting plate 219 to move downward. The downward movement of the first fitting plate 219 will push the second fitting plate 221 to overcome the damping cylinder 222 to move, and then the second fitting plate 221 will be disengaged from the slot 223. After the second fitting plate 221 is disengaged from the slot 223, the pressure-resistant shell 201 will move downward. At this time, the friction between the support plate 217 and the support plate 216 will play a buffering role. When the pressure-resistant shell 201 descends and retracts into the mounting base 215, the pressure-resistant shell 201 can be better protected to ensure that the cable body 1 can be used stably and avoid the cable body 1 from being crushed.

[0043] The surface of the pressure-resistant shell 201 is provided with anti-skid grooves, the lower end of the pressure-resistant shell 201 is flush with the top of the mounting base 215, and the top of the mounting base 215 is flush with the ground. When the wheels pass through the pressure-resistant shell 201, due to the anti-skid grooves on the surface of the pressure-resistant shell 201, the wheels are prevented from slipping when passing through the pressure-resistant shell 201, thereby reducing the stay time of the wheels on the pressure-resistant shell 201 and improving the stability of the equipment.

[0044] During the use of the present invention, when a vehicle passes through the anti-pressure part 2, the wheel will first roll over the side end of the anti-pressure shell 201, and then the wheel will climb to the top of the anti-pressure shell 201, and finally the wheel will drive out from the other side of the anti-pressure shell 201. Therefore, the second cavity 204 at the side end will be squeezed first, and then the third cavity 205 at the upper end will be squeezed, and finally the second cavity 204 on the other side will be squeezed. In this process, the pressure of the wheel on the anti-pressure shell 201 can be detected with the assistance of the pressure sensor.

[0045] When the detection value of the pressure sensor reaches the first threshold value, the second cavity 204 and the third cavity 205 are squeezed and the pressure increases in the process of the wheel passing through the pressure-resistant shell 201. At this time, since the pressure increase in the second cavity 204 and the third cavity 205 exceeds the threshold value of the pressure valve, the pressure valve will be opened, and the non-Newtonian fluid in the second cavity 204 and the third cavity 205 will slowly flow to the first cavity 202. In this way, the effect of cushioning the wheel can be achieved, the pressure when the wheel passes through the pressure-resistant shell 201 can be reduced, and the pressure-resistant shell 201 can be better protected.

[0046] When the detection value of the pressure sensor is between the first threshold and the second threshold, in order to prevent the pressure-resistant shell 201 from deforming and squeezing the wire rack 203 when the wheel passes through the pressure-resistant shell 201, the equipment controls the lifting hydraulic cylinder 213 to start. After the lifting hydraulic cylinder 213 is started, the connecting plate 214 will move downward, thereby causing the wire rack 203 to move downward. In the process of the wire rack 203 moving downward, the non-Newtonian fluid in the first cavity 202 will gather above the wire rack 203. At this time, even if the pressure-resistant shell 201 at the third cavity 205 is pressed downward and deformed, it will not squeeze the wire rack 203, thereby protecting the cable body 1 in the wire rack 203, and the non-Newtonian fluid in the first cavity 202 gathers above the wire rack 203, which can also play a better buffering role when the wheel passes through the top of the pressure-resistant shell 201.

[0047] When the wire rack 203 moves downward, the limiting plate 211 will always be in contact with the surface of the wire rack 203 with the help of the spring 212, thereby ensuring that the push plate 209 can push the non-Newtonian fluid when it moves horizontally.

[0048] When the detection value of the pressure sensor reaches the second threshold, it indicates that the gravity of the vehicle is relatively large at this time. Therefore, according to the position distribution of the vehicle tires, the equipment starts the electronically controlled two-way hydraulic cylinder 207. The output end of the electronically controlled two-way hydraulic cylinder 207 drives the output rod 208 to extend, thereby moving the push plate 209. When the push plate 209 moves, it pushes the non-Newtonian fluid in the first cavity 202 to both sides, thereby increasing the non-Newtonian fluid in the first cavity 202 corresponding to the wheel, causing the first cavity 202 to generate a reaction force at the wheel, so as to better protect the wire rack 203 and reduce the pressure on the cable body 1 in the wire rack 203.

[0049] When the detection value of the pressure sensor exceeds the second threshold value, when the wheel passes through the pressure-resistant shell 201, the first cavity 202, the second cavity 204 and the third cavity 205 are squeezed, and the non-Newtonian fluid in the pressure-resistant portion 2 is concentrated on both sides. Therefore, after the second cavity 204 is squeezed, the non-Newtonian fluid in the second cavity 204 will enter the limiting hole 218, and the pressure of the non-Newtonian fluid in the limiting hole 218 acts on the first fitting plate 219, causing the first fitting plate 219 to move downward. The downward movement will push the second mating plate 221 to overcome the damping cylinder 222 and move, thereby causing the second mating plate 221 to disengage from the slot 223. After the second mating plate 221 disengages from the slot 223, the pressure-resistant shell 201 will move downward. At this time, the friction between the support plate 217 and the support plate 216 will play a buffering role. When the pressure-resistant shell 201 descends and retracts into the mounting base 215, the pressure-resistant shell 201 can be better protected, ensuring that the cable body 1 can be used stably and avoiding the cable body 1 from being crushed.

[0050] When the speed of the passing vehicle is too fast, the physical properties of the non-Newtonian fluid can protect the anti-pressure part 2, so that the cable body 1 is well protected in the anti-pressure part 2, so that it can be used stably.

[0051] When the push plate 209 is moved to both sides with the assistance of the electronically controlled bidirectional hydraulic cylinder 207, the push plate 209 can also play a supporting role in the first cavity 202, reducing the pressure when the wheel passes through the pressure-resistant shell 201, and indirectly protecting the pressure-resistant shell 201, ensuring that the cable body 1 inside can be used stably. In addition, there will inevitably be a gap between the push plate 209 and the inner wall of the first cavity 202. Therefore, when the wheel passes through the pressure-resistant shell 201 and squeezes the first cavity 202, the non-Newtonian fluid on both sides of the first cavity 202 will also slowly enter the middle through the gap. In this way, the pressure when the wheel passes by can be buffered, ensuring the stability of the cable body 1 in use and the structural stability of the pressure-resistant shell 201.

[0052] The cable body 1 will generate heat during use. When the cable body 1 passes through the pressure-resistant part 2, since the wire rack 203 is in the first cavity 202 and there is a non-Newtonian fluid in the first cavity 202, the cable body 1 can be assisted in cooling with the assistance of the non-Newtonian fluid, making the use of the cable body 1 more stable.

[0053] The main functions realized by the present invention are as follows: by setting the first cavity 202, the second cavity 204, the third cavity 205, the pressure sensor, the electronically controlled bidirectional hydraulic cylinder 207 and the lifting hydraulic cylinder 213 and other components, the pressure of the wheel against the pressure shell 201 can be detected with the assistance of the pressure sensor, and the electronically controlled bidirectional hydraulic cylinder 207 and the lifting hydraulic cylinder 213 and other components are adjusted accordingly according to different pressures. When the detection value of the pressure sensor reaches the first threshold value, the pressure of the non-Newtonian fluid in the second cavity 204 and the third cavity 205 increases, which causes the pressure valve to open, and then slowly releases the pressure to buffer the pressure of the wheel. When the detection value of the pressure sensor is between the first threshold value and the second threshold value, the lifting hydraulic cylinder 213 is used to move the wire rack 203 downward, and the non-Newtonian fluid in the first cavity 202 will gather above the wire rack 203 to strengthen the protection of the wire rack 203. When the detection value of the pressure sensor reaches the second threshold value, the lifting hydraulic cylinder 213 is used to control the lifting hydraulic cylinder 213. The electronically controlled bidirectional hydraulic cylinder 207 moves the push plate 209, thereby pushing the non-Newtonian fluid in the first cavity 202 to both sides, so that the first cavity 202 generates a reaction force at the wheel to better protect the opposing wire rack 203. When the detection value of the pressure sensor exceeds the second threshold value, the first cavity 202, the second cavity 204 and the third cavity 205 will be squeezed, and the non-Newtonian fluid in the second cavity 204 will enter the limiting hole 218. The pressure of the non-Newtonian fluid in the limiting hole 218 acts on the first fitting plate 219. Under the cooperation of the first fitting plate 219 and the second fitting plate 221, the second fitting plate 221 is disengaged from the slot 223, thereby moving the pressure-resistant shell 201 downward. The friction between the support plate 217 and the support plate 216 will play a buffering role. When the pressure-resistant shell 201 descends and retracts into the mounting base 215, the pressure-resistant shell 201 can be better protected to ensure that the cable body 1 can be used stably.
