Description

Technical Field

[0001] The utility model relates to the technical field of cables, and in particular to a pulling-resistant charging pile cable. Background Art

[0002] With the promotion of new energy vehicles, car charging piles have also been promoted. The charging pile cable is mainly responsible for the transmission of electric energy and signal transmission. When using the cable, the cable needs to be connected to the charging port of the car, and after the car is charged, the cable should be put back into the charging pile. During this process, the cable is in a state of repeated pulling, which causes mechanical stress to be applied to the cable. In addition, the cable will produce friction with contact surfaces such as walls and the ground during the pulling process. In the long run, this mechanical stress plus the friction between the cable and the contact surface may cause wear, cracking, breakage, deformation and other conditions on the outer surface of the cable that affect the normal use of the cable, thereby resulting in a short service life of the cable. Utility Model Content

[0004] The technical solution of the utility model is as follows:

[0005] A pulling-resistant charging pile cable comprises a cable body, wherein a charging head and a connector are respectively provided at both ends of the cable body, and the cable body is provided with an anti-pulling structure, and the anti-pulling structure comprises a protective sleeve and a buffer assembly; the cable body is inserted into the protective sleeve, and the protective sleeve comprises a protective tube body and a plurality of connecting tube bodies, and each of the connecting tube bodies is respectively located between the protective tube body and the connector, and between the protective tube body and the charging head; the buffer assembly is located between the cable body and the protective sleeve, and between the connector and the charging head, and the buffer assembly comprises a filling layer and a plurality of reinforcing bodies.

[0012] Furthermore, the surfaces of the protection tube body and each connecting tube body are coated with a waterproof coating, and the waterproof coating is composed of elastic paint.

[0013] The working principle and beneficial effects of the utility model are:

[0014] 1. The cable body of the utility model is provided with a protective sleeve on the outside, which is independent of the cable body and located outside the cable body, so that when the cable is pulled, the protective sleeve generates friction with the wall or the ground, thereby reducing the wear of the cable body caused by pulling and increasing the service life of the cable.

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, this embodiment proposes a pull-resistant charging pile cable, which mainly includes a cable body 1. A charging head 2 and a connector 3 are respectively provided at both ends of the cable body 1, and the charging head 2 and the connector 3 are both connected to the cable body 1. The cable body 1 can be connected to the charging pile through the connector 3, and then the charging head 2 is connected to the car to realize charging of the car.

[0025] At the same time, the cable body 1 is provided with an anti-pull structure 4, which includes a protective sleeve 41 and a buffer component 42; the cable body 1 is inserted into the protective sleeve 41, that is, the protective sleeve 41 plays a role in protecting the cable body 1, so that when the cable body 1 is pulled, the protective sleeve 41 generates friction with the contact surface of the ground, wall, etc., thereby avoiding irreversible damage to the cable body 1 during the pulling process;

[0026] The protective sleeve 41 includes a protective tube body 411 and a plurality of connecting tube bodies 412. The protective tube body 411 and each connecting tube body 412 both cover the cable body 1, thereby ensuring that both can protect the cable body 1. Since the coverage area of ​​the protective tube body 411 is much larger than the sum of the coverage areas of each connecting tube body 412, the protection of the cable body 1 is mainly provided by the protective tube body 411. Each connecting tube body 412 is respectively located between the protective tube body 411 and the connector 3 and between the protective tube body 411 and the charging head 2. Because, when the car is charged through the cable body 1, the charging head 2 is connected to the car, and the connector 3 is connected to the charging pile. That is, both the connector 3 and the charging head 2 have fixed support points, and the cable body 1 sags under the action of gravity, thereby driving the protective sleeve 41 to sag together, resulting in a bending point on the protective sleeve 41. This reciprocating movement can easily cause the protective sleeve 41 to be damaged. Therefore, the protective sleeve 41 is designed in sections. The protective tube body 411 is mainly responsible for protecting the cable body 1, and each connecting tube body 412 connects the protective tube body 411, the connector 3, and the charging head 2. Even if damage occurs due to bending, it is the connecting tube body 412 that is damaged. In this case, only a part of the protective sleeve 41 needs to be replaced, thereby ensuring the economic benefits of this embodiment.

[0027] Moreover, each connecting tube body 412 in the present embodiment is composed of a corrugated tube, so that the connecting tube body 412 can be elastically deformed by external force when being bent, thereby reducing stress concentration and vibration transmission, and improving the durability of the connecting tube body 412; at the same time, the connecting tube body 412 has good pressure resistance and can withstand higher internal and external pressures, so that the part of the cable body 1 located at the connecting tube body 412 can also be better protected.

[0028] like Figure 2 As shown, the buffer component 42 in this embodiment is located between the cable body 1 and the protective sleeve 41, and between the connector 3 and the charging head 2. The buffer component 42 includes a filling layer 421 and a plurality of reinforcing bodies 422. That is, through the cooperation of the filling layer 421 and the plurality of reinforcing bodies 422, the protective sleeve 41 is supported to prevent the protective sleeve 41 from deforming toward the cable body 1 when subjected to external pressure such as pressing force, thereby causing external force to act on the cable body 1 and causing damage to the cable body 1, thereby improving the protective effect of the protective sleeve 41.

[0029] The reinforcement bodies 422 are evenly distributed around the cable body 1 in a circumference, and the reinforcement bodies 422 are fixedly connected to the cable body 1. The reinforcement bodies 422 are all arch structures, that is, by means of the special geometric shape of the arch structure, when subjected to force (deformation of the protective sleeve 41), the gravity and external load are dispersed and transmitted to the cable body 1 in the form of pressure, thereby dispersing the pressure. When the protective sleeve 41 undergoes unavoidable deformation, the pressure is prevented from directly acting on the cable body 1, thereby reducing the probability of damage to the cable body 1.

[0030] like Figure 2~Figure 3 As shown, a plurality of elastic members 5 are provided between the cable body 1 and the protective sleeve 41 in the present embodiment. The elastic members 5 are preferably compression springs, and both ends of each elastic member 5 are respectively fixedly connected to the charging head 2 and the connecting head 3, that is, by virtue of the characteristics of the compression spring that deforms, absorbs and stores energy under force, the tension in the axial direction of the cable body 1 is buffered, thereby avoiding excessive tension that causes the cable body 1 to be stretched straight all of a sudden, resulting in stress that may be concentrated in a certain area of ​​the cable body 1, generating uncertain factors; and each elastic member 5 is located one by one between each reinforcement body 422 and the cable body 1. Although the buffering effect of the compression spring in the radial direction is limited, when the reinforcement body 422 is deformed under force, with the help of this position design, the elastic member 5 can play a certain buffering role in a comprehensive manner such as elasticity and physical buffering.

[0031] Because the connecting tube body 412 is made of a corrugated tube, the strength of the connecting tube body 412 is limited. When the force is deformed to a certain extent, the reinforcing body 422 may cause damage to the connecting tube body 412. To avoid contact between the reinforcing body 422 and the connecting tube body 412, the length of each reinforcing body 422 is less than or equal to the length of the protective tube body 411. Each reinforcing body 422 is made of a polyurethane elastomer, which makes the reinforcing body 422 have a certain elasticity and improves the buffering capacity of the reinforcing body 422.

[0032] There is a gap between the filling layer 421 and each connecting tube body 412 to prevent the connecting tube body 412 from interfering with the filling layer 421 during deformation, causing the connecting tube body 412 to be in a state of multiple deformations and affecting the resetting process of the connecting tube body 412.

[0033] The filling layer 421 in this embodiment should preferably be made of wear-resistant and insulating elastic materials such as rubber, so that the filling layer 421 has an insulating effect while having a buffering effect, and is relatively durable, fully ensuring the practicality of this embodiment. The filling layer 421 is provided with a plurality of accommodating cavities 4211, which are convenient for each reinforcement body 422 and each elastic member 5 to be installed in the filling layer 421, and the design can make each reinforcement body 422 and each elastic member 5 be embedded in the filling layer 421, so that each reinforcement body 422 and each elastic member 5 are surrounded by a filling material made of wear-resistant and insulating elastic materials such as rubber. When each reinforcement body 422 and each elastic member 5 play a buffering role, the filling layer 421 can also play a buffering role for each reinforcement body 422 and each elastic member 5, thereby improving the buffering effect of the buffer assembly 42 in this embodiment.

[0034] The surfaces of the protective tube body 411 and each connecting tube body 412 in this embodiment are coated with a waterproof coating 6. Even if the protective sleeve 41 has moisture-proof and waterproof functions, this embodiment is prevented from being easily affected by a humid environment. The waterproof coating 6 is made of elastic paint, that is, the waterproof coating 6 in this embodiment can expand and contract when slight deformation or cracking occurs on the surface of the protective sleeve 41, thereby effectively preventing the coating from cracking or falling off, thereby ensuring the practicality of the embodiment.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
