[0025] Example 1

[0026] like Figures 1-3 As shown, a charging gun cable protection device includes a base plate 1, an elastic support member 2, and a sealing sleeve 3. The sealing sleeve 3 is disposed on the inner side of the base plate 1 to seal the inner end of the cable. The elastic support member 2 is disposed on the outer side of the base plate 1 to elastically support the outer end of the cable and has a vibration damping and buffering protection function. The elastic support member 2 includes an elastic member 21 and an elastic support body 22 covering the outer side of the elastic member 21.

[0027] like Figure 3 As shown, the elastic element 21 is a cylindrical steel wire spring, and the elastic support 22 is fixedly connected to the elastic element through injection molding. When the charging gun charges the car, the cable bends, and the cylindrical steel wire spring can greatly reduce the vibration of the cable and prevent the cable from bending excessively, thus playing a role in vibration damping and buffering protection.

[0028] To improve the vibration damping and buffering effect, such as Figures 1-3 As shown, the elastic support 22 has multiple arc-shaped protrusions 23 on its outer side along the axial direction, and a through hole 24 coaxially arranged with the sealing sleeve 3 on its inner side.

[0029] like Figure 1 , 3 As shown, the sealing sleeve 3 is a conical body, with its diameter gradually decreasing as it extends away from the substrate 1, and the end of the sealing sleeve 3 away from the substrate 1 is an open end 31, the inner diameter of which is not greater than the outer diameter of the cable.

[0030] like Figure 3As shown in the above charging gun wire protection device further includes a sealing sleeve two 4, the sealing sleeve two 4 is arranged in the wire hole 24 of the elastic support 2, located in the inside end of the through hole 24, close to the base plate 1 is set;The sealing sleeve two 4 and the sealing sleeve one 3 are coaxially arranged, and are conical bodies extending in the same direction with the sealing sleeve one 3. Through the setting of the sealing sleeve one 3 and the sealing sleeve two 4, the double-layer sealing of the cable is realized, the cable is sealed and protected, the external dust or water vapor is prevented from entering, and the failure of the internal electrical components of the charging gun is avoided.

[0031] In addition, one end of the sealing sleeve two 4 close to the sealing sleeve one 3 is provided with a sealing easy-to-tear opening 41, and the easy-to-tear opening 41 of the sealing sleeve two 4 is closed when not in use, and the flexibility is good. The inner diameter of the easy-to-tear opening 41 is not greater than the inner diameter of the open end 31 of the sealing sleeve one 3, so that a better double-layer sealing effect is realized.

[0032] In summary, the utility model has the advantages of simple structure, double-layer sealing, good sealing effect, vibration damping and buffering protection for the cable, and long service life of the cable and the charging gun. In addition, the wire protection device of the utility model can also be applied to the sealing protection of the pipeline.

The structure is simple and convenient to manufacture. Since the complete elastic silicone sealing is adopted, the cable stress is small, the bending angle is large, and the phenomenon of cable breakage caused by cable stress cannot be released can be avoided, and the service life of the cable is improved.

[0036] As shown in the above, Figure 1 , 3As shown, the inner side of the substrate 1 is provided with a sealing rib along the peripheral side of the substrate 1, which protrudes from the inner side of the substrate 1 and is integrally formed with the elastic outer layer 12. Specifically, the sealing rib is provided with double layers, i.e. an outer sealing rib 14 and an inner sealing rib 15, the height of the outer sealing rib 14 is higher than that of the inner sealing rib 15, and when the outer sealing rib 14 fails due to wear, the inner sealing rib 15 can still provide sealing; and the corner of the inner sealing rib 15 is further provided with a corner sealing rib 16, which forms a quadrilateral sealing body with the inner sealing rib 15 around the peripheral side of the mounting hole 13, which can ensure the sealing of the mounting hole 13, prevent external dust or water vapor from entering the inside through the gap between the mounting holes, and improve the sealing effect.
