Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be noted that the embodiments described herein are only exemplary and should not be construed as limiting the scope of the present invention.
Referring first to fig. 1, the structure of a prior art charging cable is shown. As shown in fig. 1, the PE ground wire 2 of the charging cable is a solid wire with a circular cross section, and the ground wire 2 occupies a relatively large cross-sectional area in the entire charging cable, resulting in a large wire diameter and a large weight of the entire charging cable. In order to solve the problem, the utility model provides a novel charging cable, the grounding wire of the charging cable is in a metal mesh grid form, and the grounding wire structure in the form can reduce the wire diameter of the charging cable, reduce the weight of the charging cable, improve the use convenience and improve the user experience.
Preferred embodiments of the present invention are further described below in conjunction with fig. 2-4.
As shown in fig. 2, the charging cable of the present invention includes a power wire 1 and a ground wire 2, and the ground wire 2 is in the form of a metal mesh.
Preferably, the metal woven mesh of the earth wire 2 has a macroscopic form of a hollow metal mesh sheath. In addition, the charging cable further comprises a signal wire 3, the signal wire 3 is accommodated in the hollow metal mesh sleeve of the grounding wire 2, the wire diameter of the charging cable can be reduced, and the grounding wire 2 can also play a role of a shielding layer, so that the influence of an external electromagnetic field on the signal wire is reduced.
Specifically, the ground wire 2 in the form of a hollow metal mesh can be provided as a circular hollow metal mesh, and such an arrangement can enable the ground wire 2 to be placed in parallel with other cables in the charging cable better while functioning as a shielding layer.
It should be noted that, although the macroscopic form of the grounding wire 2 shown in fig. 2 is a circular hollow metal mesh, this is not limitative, and a person skilled in the art may set the macroscopic form of the grounding wire 2 in other forms, for example, in the form of a flat hollow metal mesh, as shown in fig. 3, if necessary. As will be understood by those skilled in the art, such an arrangement allows the ground wire 2 to more conveniently fill the charging cable while functioning as a shield.
Furthermore, as shown in fig. 4, the ground wire 2 may also be provided in the form of an unsealed metal mesh. Accordingly, this embodiment considers more the encapsulation of the ground wire 2 in the charging cable and its spatial compatibility with other wires, with less effect as a shielding layer.
Furthermore, the power lines 1 shown in fig. 2-4 may be DC + and DC-lines for power transmission and a + and a-lines as auxiliary power sources, but may also include other power lines related to power transmission. The signal line 3 may be a CC line for pilot connection confirmation and CAN + and CAN-lines for vehicle communication, etc.
Preferably, the metal mesh grid of the earth wire 2 may be woven by weaving round copper wires having a wire diameter of not more than 0.2mm in a form of a plurality of strands in a single layer or a plurality of layers, and the metal mesh grid after weaving has a direct current resistivity of not more than 0.02 Ω (mm)2And/m. The woven metal mesh grounding wire 2 is softer, the signal wire can be better filled in the metal mesh grounding wire 2, and the outside of the grounding wire 2 is wrapped by an insulating material.
It should be noted that, although the grounding wire 2 is woven by a round copper wire with a wire diameter of not more than 0.2mm, this is not restrictive, and those skilled in the art may use other sizes of metal wires to make the metal mesh of the grounding wire 2. For example, it can be formed by weaving a tin-plated soft round copper wire having a wire diameter of not more than 0.15mm in a single layer or a plurality of layers, and the direct current resistivity of the metal woven mesh after weaving is not more than 0.02 Ω (mm)2/m。
The charging gun comprises the charging gun head and the charging cable, and when the grounding wire 2 in the charging cable is in a metal mesh grid form, the wire diameter of the charging cable can be reduced by more than 10%. The charging cable is in compression joint or welding with the charging gun head, so that the metal mesh grid of the grounding wire 2 is tightly connected with the charging gun head.
The charging equipment comprises a power supply device and the charging gun, wherein a charging cable is connected between the power supply device and the charging gun head.
Preferably, the power supply device of the charging device is a charging pile or a mobile charging vehicle. Of course, other forms of power supply may be used.
