[0025] To keep the following description of the embodiments of the present disclosure clear and concise, detailed descriptions of known functions and components are omitted in this disclosure.

[0026] To illustrate the technical solutions of the present disclosure, descriptions are provided through the following specific embodiments.

[0027] Embodiment I of the present disclosure provides a charging gun cable 10. As shown in FIG. 1 , the charging gun cable 10 includes a first L wire 11, an N wire 14, a PE wire 12, and a CP wire 13. The first L wire 11, the N wire 14, and the PE wire 12 are arranged adjacent to each other. The PE wire 12 has a hollow hole. The CP wire 13 is positioned within the hollow hole of the PE wire 12.

[0028] The first L wire 11 is a single-phase alternating current (AC) wire. The N wire 14 is an AC neutral wire. The PE wire 12 is a ground wire of the charging gun configured to connect the charging gun and the vehicle to a common ground. The CP wire 13 is a control guide cable for monitoring the interaction function between the electric vehicle and the electric vehicle power supply device.

[0029] The fact that the PE wire 12 has a hollow hole means that the PE wire 12 is a hollow wire, the center of the wire harness is hollow, and the CP wire 13 is positioned within the hollow hole of the PE wire 12, so that the PE wire 12 forms a blocking layer for the CP wire 13.

[0030] The present disclosure provides a charging gun cable 10. The charging gun cable 10 includes a first L wire 11, an N wire 14, a PE wire 12, and a CP wire 13. The PE wire 12 has a hollow hole, and the CP wire 13 is positioned within the hollow hole of the PE wire 12. According to the present disclosure, the CP wire 13 is positioned within the hollow hole of the PE wire 12, so that the PE wire 12 not only fulfills the grounding function but also shields the CP wire 13. The PE wire 12 is reused as a shielding wire to prevent interference with the CP wire 13 during signal transmission. In addition, the PE wire 12, which has the same diameter as the original wire, is used as a shielding wire, so the function of the original PE wire 12 is not affected.

[0031] Regarding the positional relationship between the PE wire 12 and the CP wire 13, the CP wire 13 is positioned inside the PE wire 12, and the outer surface of the CP wire 13 may be in partial contact with the inner surface of the PE wire 12 or may be in complete contact with the inner surface of the PE wire 12. In one implementation, the PE wire 12 is a metal layer that wraps around the CP wire 13. Preferably, the CP wire 13 and the PE wire 12 are coaxially arranged, and the technical effect of this implementation is that the PE wire 12 tightly wraps around the CP wire 13, thereby improving the blocking effect on the CP wire 13.

[0032] Regarding the connection between the CP wire 13 and other modules, the CP wire 13 extends through a hole in the PE wire 12 and connects to the control device of the charging pile. To realize the connection between the CP wire 13 and other modules, the PE wire 12 near the control device inside the charging pile is provided with a hole through which the CP wire 13 passes.

[0033] Regarding the category of the charging gun cable 10 shown in FIG. 1, if the category of the charging gun cable 10 is a single-phase AC charging cable, the charging gun cable includes only the first L wire 11. As shown in FIG. 2, if the category of the charging gun cable 10 is a three-phase AC charging cable, the charging gun cable 10 further includes a second L wire 15 and a third L wire 16. The first L wire 11, the second L wire 15, the third L wire 16, the N wire 14, and the PE wire 12 are arranged adjacent to each other in order. One arrangement is where the first L wire 11, the second L wire 15, the third L wire 16, the N wire 14, and the PE wire 12 form a loop. Another arrangement is a double-row arrangement where the first L wire 11, the second L wire 15, and the third L wire 16 are arranged in a first row, and the N wire 14 and the PE wire 12 are arranged in a second row. The charging gun cable 10 provided in this embodiment can be used as both a single-phase AC charging cable and a three-phase AC charging cable.

[0034] Embodiment II of the present disclosure provides a charging gun including a charging gun body and a charging gun head. The charging gun head includes the charging gun cable provided in embodiment I. The charging gun cable extends through the charging gun body and connects to a charging pile.

[0035] Embodiment III of the present disclosure provides a charging pile, including a charging pile body 30 and the charging gun 20 provided in Embodiment II.

[0036] 3, the charging pile is a single-phase charging pile, and the charging pile body 30 includes a switching device 31 and a control device 32. The switching device 31 connects the first L wire to the N wire. The communication terminal of the control device 32 is connected to the CP wire, and the ground terminal of the control device 32 is connected to the PE wire.

[0037] In this implementation, in a single-phase charging pile, the CP wire is placed in the hollow hole of the PE wire, so that the PE wire not only realizes the grounding function but also shields the CP wire, which is reused as a shielding wire to prevent the CP wire from being interfered with during signal transmission.

[0038] In another implementation, the charging pile is a three-phase charging pile. The charging pile body includes a switching device and a control device. The switching device connects the first L wire, the second L wire, the third L wire, and the N wire. The communication terminal of the control device is connected to the CP wire, and the ground terminal of the control device is connected to the PE wire.

[0039] In this implementation, in a three-phase charging pile, the CP wire is placed in the hollow hole of the PE wire, so that the PE wire not only realizes the grounding function but also shields the CP wire, and the PE wire is reused as a shielding wire to prevent the CP wire from being interfered with during signal transmission.

[0040] The above is a further detailed description of the present disclosure with reference to specific preferred implementations, and the specific implementations of the present disclosure should not be considered limited to these descriptions. All equivalent substitutes or obvious variations that can be made by those skilled in the art of the present disclosure without departing from the concept of the present disclosure and have the same performance or application should be considered to fall within the scope of patent protection determined by the scope of the claims of the present disclosure.
