Description

Technical Field

[0001] The utility model is an electric control flexible cable for new energy vehicles, belonging to the technical field of new energy cable equipment. Background Art

[0002] At present, the cable cores of the known electric vehicle conductive DC charging system are all directly twisted by the DC power core, the protective grounding core, the auxiliary power core, the charging signal core and the charging control core. It is one of the key equipment of the electric vehicle conductive charging system, and is mainly used for the connection between the charging gun and the power supply when the electric vehicle is charged, which can ensure the fast, safe and reliable charging process. The slightly larger DC charging system cable has a larger outer diameter due to its larger conductive core cross-sectional area and more cores, which reduces its flexibility. The DC charging system cable needs to be dragged repeatedly during use, and its poor flexibility greatly increases the difficulty of operation during charging.

[0003] Patent No.: CN207503666U, mentions a flexible cable for an electric vehicle conduction DC charging system, which is made by a cabling method combining back-twisting, co-directional re-twisting and bundle twisting, and the bundle twisting pitch ratio of the strand bundle is not less than the re-twisting pitch ratio of the core, so that the strands are clearly arranged, which can not only achieve the balance of the tension of each conductor single wire in the strand bundle, but also avoid or reduce the breakage of the conductor single wire during the production and use process. The whole strand bundle has sufficient good mechanical properties of tensile resistance, bending resistance and extrusion resistance, and effectively ensures the twisting tightness between the conductor single wire and the strand bundle, which prevents loose strands and avoids excessive embedding between adjacent conductor single wires, thereby ensuring the twisting flexibility of the cable. However, the cable needs to be dragged repeatedly during use. When the cable is pulled out for a long time, its external drooping end will fall on the outside ground. During the repeated dragging process, the outer side of the cable will contact and rub against the outside ground. If this happens for a long time, the cable surface will be worn. Now there is an urgent need for electronically controlled flexible cables for new energy vehicles to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an electronically controlled flexible cable for new energy vehicles to solve the problems raised in the above-mentioned background technology. The utility model has a reasonable structure and good practicality. The overall structure adopts a twisted copper wire structure, and the sheath adopts a low-viscosity flexible wear-resistant material to reduce the wear rate of the cable during continuous reciprocating movement. At the same time, a flexible sliding protective cover structure is designed, which can slide to the drooping end of the cable according to the principle of center of gravity, thereby preventing the drooping end of the cable from directly contacting the outside ground.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an electric control flexible cable for new energy vehicles, comprising a low-viscosity outer sheath, a flexible protective sheath, an elastic rubber sheet and a counterweight slider, a shielding layer is arranged on the inner side of the low-viscosity outer sheath, a woven tape layer is arranged on the inner side of the shielding layer, a filling layer is arranged on the inner side of the woven tape layer, a first conductor, a second conductor, a third conductor, a combined conductor and a sixth category soft conductor single wire are arranged on the inner side of the filling layer, the flexible protective sheath sliding sleeve is arranged on the outside of the low-viscosity outer sheath, and a plurality of open grooves are opened at equal distances from left to right at the upper end of the flexible protective sheath, a plurality of arc grooves are opened at equal distances at the lower end of the flexible protective sheath, elastic rubber sheets are arranged at the plurality of arc grooves, and a plurality of counterweight sliders are arranged at equal distances at the lower ends of the plurality of arc grooves.

[0009] Furthermore, the plurality of counterweight sliding blocks are all slidably attached to the lower end of the low-viscosity outer sheath.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: an electric control flexible cable for new energy vehicles, comprising a low-viscosity outer sheath 1, a flexible protective sheath 10, an elastic rubber sheet 13 and a counterweight slider 14, a shielding layer 2 is arranged inside the low-viscosity outer sheath 1, a braided tape layer 3 is arranged inside the shielding layer 2, a filling layer 4 is arranged inside the braided tape layer 3, a first conductor 5, a second conductor 6, a third conductor 7, a combined conductor 8 and a sixth-category soft conductor single wire 9 are arranged inside the filling layer 4, and the flexible protective sheath 10 is slidably sleeved on the low-viscosity outer sheath. 1, and a plurality of opening grooves 11 are opened at equal distances from left to right at the upper end of the flexible protective cover 10, a plurality of arc grooves 12 are opened at equal distances at the lower end of the flexible protective cover 10, elastic rubber sheets 13 are arranged at the plurality of arc grooves 12, and a plurality of counterweight sliders 14 are arranged at equal distances at the lower ends of the plurality of arc grooves 12. This design solves the problem that the drooping end of the original cable will fall on the external ground, and the outer side of the cable will contact and rub against the external ground during repeated dragging, which will cause the cable surface to wear over a long period of time.

[0019] As the first embodiment of the utility model: the combined conductor 8 is composed of a charging signal core and a charging control core. The first conductor 5, the second conductor 6, the third conductor 7, the combined conductor 8 and the sixth type soft conductor single wire 9 are all provided with an insulating layer on the outside. The added insulating layer can protect the sealing insulation of each conductor. The first conductor 5, the second conductor 6 and the third conductor 7 are respectively the DC power core, the protective grounding core and the auxiliary power core. The multiple counterweight sliders 14 are all slidably attached to the lower end of the low-viscosity outer sheath 1. The added low-viscosity outer sheath 1 is a flexible wear-resistant rubber material, which will not affect the overall flexibility of the cable. The first conductor 5, the second conductor 6 and the third conductor 7 are a twisted copper wire structure. By setting the first conductor 5, the second conductor 6 and the third conductor 7 as a twisted copper wire structure, it is much softer than a single copper wire of the same diameter, and the bending performance of the made wire is also better.

[0020] As a second embodiment of the utility model: the added low-viscosity outer sheath 1 is a flexible wear-resistant rubber material, which will not affect the overall flexibility of the cable. The first conductor 5, the second conductor 6 and the third conductor 7 are set as a twisted copper wire structure, which is much softer than a single copper wire of the same diameter. The bending performance of the wire is also better. In actual use, due to the setting of multiple counterweight sliders 14, the flexible protective sheath 10 will slide to the drooping end of the cable according to the principle of center of gravity (so that the center of gravity of the multiple counterweight sliders 14 is downward, still in Figure 2 As shown in the state), the hanging end of the cable can be prevented from directly contacting the outside ground, and when the hanging end of the cable is flexibly deformed, the flexible protective cover 10 is deformed accordingly. At this time, the width of the multiple opening slots 11 becomes smaller, and the multiple elastic rubber sheets 13 are partially unfolded (reference Figure 1 ).

[0021] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
