[0039] A movable member 32, the movable member 32 is movably sleeved on the outer wall of the cable 20 and is located at a side of the fixed member 31 away from the gun head 10;

[0040] A plurality of skeleton components 33, wherein the skeleton components 33 include a first skeleton 331 and a second skeleton 332, wherein the first skeleton 331 has a first end 3311 and a second end 3312, and the second skeleton 332 has a third end 3321 and a transition portion 3323, wherein the first end 3311 is rotatably connected to the movable member 32, the third end 3321 is rotatably connected to the fixed member 31, and the second end 3312 is rotatably connected to the transition portion 3323; and a plurality of spacing rings of the skeleton components 33 are arranged on the outer walls of the fixed member 31 and the movable member 32;

[0041] The cover body 35 has one end connected to the fixing member 31 , and the other end fixedly connected to the second frame 332 .

[0042] In the technical solution adopted in this embodiment, the charging gun 100 includes a gun head 10, which is used to be plugged into the socket on the new energy vehicle. A cable 20 is provided at the tail end of the gun head 10, and the cable 20 can supply power to the gun head 10, so that the electric energy can be transmitted from the gun head 10 to the socket on the new energy vehicle, and then supply power to the battery in the new energy vehicle. The charging gun 100 is also provided with a waterproof part 30, and the waterproof part 30 includes a fixed part 31, a movable part 32, a plurality of skeletons and a cover body 35. The fixed part 31 is fixedly sleeved on the outer wall of the cable 20, and the movable part 32 is movably sleeved on the outer wall of the cable 20 and is located at one end of the fixed part 31 away from the gun head 10. In this way, the movable part 32 can move axially along the cable 20 to approach the fixed part 31 or move axially along the cable 20 away from the fixed part 31, thereby changing the distance between the fixed part 31 and the movable part 32. Multiple skeleton components 33 are arranged on the outer walls of the fixed part 31 and the movable part 32. Each skeleton assembly 33 includes a first skeleton 331 and a second skeleton 332. The first end 3311 of the first skeleton 331 is rotatably connected to the movable member 32. The second end 3312 of the first skeleton 331 is rotatably connected to the adapter 3323 on the second skeleton 332. The third end 3321 of the second skeleton 332 is rotatably connected to the fixed member 31. In this configuration, when the movable member 32 moves away from the fixed member 31, since the third end 3321 is rotatably connected to the fixed member 31, the first end 3311 is rotatably connected to the movable member 32, and the second end 3312 is rotatably connected to the adapter 3323, the end of the second skeleton 332 away from the third end 3321 rotates around the third end 3321 toward the direction close to the cable 20 until the movable member 32 moves away from the fixed member 31. Figure 1 As shown, the cover 35 surrounds the cable 20. When the movable member 32 approaches the fixed member 31, as shown in FIG. Figure 2As shown, since the third end 3321 is rotatably connected to the fixing member 31, the first end 3311 is rotatably connected to the movable member 32, and the second end 3312 is rotatably connected to the adapter 3323, the end of the second frame 332 away from the third end 3321 rotates around the third end 3321 in a direction away from the cable 20. When the movable member 32 abuts against the fixing member 31, as shown in FIG. Figure 4 As shown, the cover 35 surrounds the gun head 10, and the cover 35 can contact the body of the new energy vehicle. Rainwater will flow out along the cover 35 and will not enter the gun head 10 and the socket connection, protecting the charging safety. Preferably, the cover 35 is a rainproof cloth or plastic cloth. Optionally, the cover 35 is made of transparent material.

[0043] Furthermore, in one embodiment of the utility model, a fourth end 3322 is provided on a side of the second skeleton 332 away from the third end 3321 and the adapter 3323 , one end of the cover body 35 is connected to the fixing member 31 , and the other end of the cover body 35 is fixedly connected to the fourth end 3322 .

[0044] It is understandable that the third end 3321 of the second skeleton 332 is rotatably connected to the fixing member 31, the end of the second skeleton 332 away from the third end 3321 is the fourth end 3322, and the adapter 3323 is located between the third end 3321 and the fourth end 3322. Preferably, the first skeleton 331 and the second skeleton 332 are both rod-shaped. Preferably, the adapter 3323 is a protrusion on the first skeleton 331. It is understandable that connecting one end of the cover body 35 to the fixing member 31 and the other end of the cover body 35 to the fourth end 3322 can maximize the coverage of the cover body 35. It is understandable that in the initial position, as Figure 1 As shown, at this time, the cover body 35 surrounds the cable 20, and the projection of the fourth end 3322 on the cable 20 is located at the end of the fixing part 31 away from the gun head 10. As the movable part 32 gets closer and closer to the fixing part 31, the distance between the fourth end 3322 and the cable 20 becomes farther and farther, and the projection of the fourth end 3322 on the cable 20 becomes closer and closer to the fixing part 31. When the projection of the fourth end on the cable 20 overlaps with the fixing part 31, at this time, the distance between the fourth end 3322 and the cable 20 is the farthest. Continue to push the movable part 32 toward the fixing part 31. At this time, the projection of the fourth end 3322 on the cable 20 is located at the end of the fixing part 31 close to the gun head 10, and the distance between the fourth end 3322 and the cable 20 becomes smaller and smaller as the movable part 32 moves. When the movable part 32 and the fixing part 31 are in contact, as shown in FIG. Figure 4 As shown, at this time, the fourth end 3322 is located around the gun head 10 , so that the entire cover body 35 will surround the gun head 10 .
