DETAILED DESCRIPTION

[0050] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0051] The terms used in the embodiments of the present disclosure are only used to explain the embodiments of the present disclosure, and are not intended to limit the present disclosure.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0052] Nowadays, with the development of new energy technology, the number of electric vehicles has increased year by year. Correspondingly, as the supporting charging facilities for electric vehicles, the number of charging piles has also increased. Charging piles include electric piles, cables and electric guns. Figure 1 is a schematic diagram of a connection between an electric gun and a cable shown in an embodiment of the present disclosure, such as Figure 1 As shown, the electric gun includes a housing and a charging terminal, the charging terminal is fixed in the housing, and the charging terminal has a slot structure. One end of the cable extends into the housing and is engaged with the slot structure, and the other end of the cable is electrically connected to the electric pile, so that the electric gun and the electric pile are electrically connected. However, in the above structure, the cable and the electric gun are connected only by the interference fit between the cable end and the charging terminal, and the connection reliability is poor. If the user grasps the cable to plug in and out the electric gun, the cable may be separated from the charging terminal, resulting in failure of the electrical connection between the electric pile and the electric gun.

[0053] The present disclosure provides a cable assembly 01, such as Figure 2 As shown, the cable assembly 01 includes a cable 1 and a limiting member 2 .

[0054] Among them, the limiting member 2 includes a connecting portion 20, a first protruding portion 21 and a second protruding portion 22. The connecting portion 20 is sleeved on the outside of the cable 1 and fixedly connected to the cable 1. The first protruding portion 21 and the second protruding portion 22 are spaced apart in the extension direction of the cable 1 and are respectively connected to the connecting portion 20. The first protruding portion 21 and the second protruding portion 22 are used to cooperate with the housing 02 of the electrical appliance to limit the movement of the cable 1 in the extension direction.

[0055] By adopting the technical solution provided by the embodiment of the present disclosure, compared with Figure 1 The technical solution shown in the figure adds a limiter 2, so that when the cable assembly 01 is connected to the electric appliance (electric gun), not only the cable 1 is connected to the charging terminal in the electric gun, but also the limiter 2 is connected to the housing 02 of the electric appliance, thereby improving the connection reliability between the cable assembly 01 and the electric gun. Therefore, when the user grasps the cable assembly 01 to plug or unplug the electric gun, the electrical connection between the cable assembly 01 and the electric gun is not easy to fail.

[0056] It is understandable that the application of the above-mentioned cable assembly 01 to other electrical appliances can also improve the connection reliability between the cable assembly 01 and the electrical appliances, thereby making the electrical connection between the cable assembly 01 and the electrical appliances less likely to fail.

[0057] In some possible embodiments, Figure 2 As shown, the first protruding portion 21 and the second protruding portion 22 are located at two ends of the limiting member 2 .

[0058] In some examples, the connecting portion 20 has a cylindrical structure, is sleeved outside the cable 1 and is fixedly connected to the cable 1 , and the first protrusion 21 and the second protrusion 22 are both located outside the connecting portion 20 and are connected to both ends of the connecting portion 20 .

[0059] Optionally, the connecting portion 20, the first protruding portion 21 and the second protruding portion 22 may be integrally formed parts. The first protruding portion 21 and the second protruding portion 22 may be formed by a pressurized injection molding process, or the first protruding portion 21 and the second protruding portion 22 may be formed by a cutting process, which is not limited in the present embodiment.

[0060] Optionally, the connection between the connection part 20 and the cable 1 may be by bonding, or the connection between the connection part 20 and the cable 1 may be by snapping, which is not limited in the embodiments of the present disclosure.

[0061] Optionally, the limit member 2 can be made of non-conductive materials such as engineering plastics, or the limit member 2 can be made of conductive materials such as metals. The embodiments of the present disclosure do not limit this. It can be understood that when the limit member 2 is made of conductive materials such as metals, the limit member 2 should be completely arranged inside the housing 02 of the electrical appliance to prevent the user from touching the limit member 2 and getting an electric shock.

[0062] In some examples, the limiting member 2 has a structure in which the middle is concave and the two ends are raised. Specifically, Figure 2 As shown, the recessed portion is the connecting portion 20, and the two raised ends are respectively the first protruding portion 21 and the second protruding portion 22.

[0063] In practice, the limit member 2 can be stamped from a cylindrical structure. Specifically, before the limit member 2 is assembled to the outside of the cable 1, it can be a cylindrical structure, and the cylindrical structure can be a circular cylindrical structure or a square cylindrical structure, which is not limited in the embodiments of the present disclosure. The inner diameter of the cylindrical structure is larger than the outer diameter of the cable 1 (it can be understood that in the case of a square cylindrical structure, the distance between the two opposite inner walls of the square cylindrical structure is larger than the outer diameter of the cable 1), so that the cylindrical structure can be smoothly mounted on the outside of the cable 1, and then the cylindrical structure can be processed using a processing tool to deform the cylindrical structure into the limit member 2, and the limit member 2 is fixedly connected to the outside of the cable 1.

[0064] Of course, the first protrusion 21 and the second protrusion 22 may also be located in the middle of the stopper 2. In some examples, the connecting portion 20 has a cylindrical structure, and the first protrusion 21 and the second protrusion 22 are both located outside the connecting portion 20, between the two ends of the connecting portion 20, and connected to the connecting portion 20.

[0065] In one example, the connecting portion 20 may be in a prismatic structure.

[0066] In practice, the cylindrical structure may be machined by a machining tool to form the connecting portion 20 and make the portion have a prismatic structure.

[0067] Exemplarily, the connecting portion 20 may be in a quadrangular prism structure, a hexagonal prism structure, or an octagonal prism structure, which is not limited in the embodiments of the present disclosure.

[0068] In one example, the stopper 2 is assembled to the outside of the cable 1, and at least a portion of the connection portion 20 is recessed in a direction close to the cable 1, so that the connection portion 20 and the cable 1 have an interference fit. Specifically, the connection portion 20 has a cylindrical structure, and at least a portion of the inner wall of the connection portion 20 is recessed in an axial direction of the cable 1, so that the connection portion 20 and the cable 1 have an interference fit.

[0069] In some possible embodiments, the first protrusion 21 is used to cooperate with the housing 02 of the electrical appliance to limit the movement of the cable 1 in the first direction, and the second protrusion 22 is used to cooperate with the housing 02 of the electrical appliance to limit the movement of the cable 1 in the second direction.

[0070] The first direction is opposite to the second direction, and both the first direction and the second direction are parallel to the extension direction of the cable 1 .

[0071] By adopting the technical direction provided by the embodiment of the present disclosure, the limiter 2 is fixedly connected to the outer wall of the cable 1, and the limiter 2 includes a first protrusion 21 and a second protrusion 22, and the first protrusion 21 and the second protrusion 22 are only used to limit the cable 1 in a single direction, that is, when the cable 1 has a tendency to move along the first direction, the first protrusion 21 has a limiting effect on the cable 1, and when the cable 1 has a tendency to move along the second direction, the second protrusion 22 has a limiting effect on the cable 1. In this way, compared with the limiter using only one protrusion, in the limiter 2 provided by the embodiment of the present disclosure, the first protrusion 21 and the second protrusion 22 will not receive cyclic loads, thereby improving the fatigue resistance of the limiter 2, and further improving the service life of the cable assembly 01 and the electrical appliance.

[0072] Specifically, Figure 3 As shown, the first protrusion 21 and the second protrusion 22 are distributed at both ends of the limiter 2, the first protrusion 21 is used to cooperate with the housing 02 of the electrical appliance to limit the movement of the cable 1 in the first direction, and the second protrusion 22 is used to cooperate with the housing 02 of the electrical appliance to limit the movement of the cable 1 in the second direction. The first direction is the direction in which the second protrusion 22 points to the first protrusion 21, and the second direction is the direction in which the first protrusion 21 points to the second protrusion 22.

[0073] In some examples, two wall surfaces of the first protrusion 21 and the second protrusion 22 that are separated from each other in the extension direction of the cable 1 are respectively used to cooperate with the housing 02 of the electrical appliance.

[0074] like Figure 4 As shown ( Figure 4 for Figure 3 As shown in the half-section schematic diagram corresponding to the cable assembly 01, the housing 02 of the electrical appliance has two limiting structures, one of which is located on the side of the first protrusion 21 away from the second protrusion 22, and is against the wall of the first protrusion 21 away from the second protrusion 22, and the other limiting structure is located on the side of the second protrusion 22 away from the first protrusion 21, and is against the wall of the second protrusion 22 away from the first protrusion 21.

[0075] In some examples, two adjacent wall surfaces of the first protrusion 21 and the second protrusion 22 in the extension direction of the cable 1 are respectively used to cooperate with the housing 02 of the electrical appliance.

[0076] like Figure 6 As shown ( Figure 6 for Figure 51 ), the housing 02 of the electrical appliance has a limiting structure, which is located between the first protrusion 21 and the second protrusion 22, and the length of the limiting structure in the extension direction of the cable 1 is equal to the distance between the first protrusion 21 and the second protrusion 22. The two opposite walls of the limiting structure are respectively against the two adjacent walls of the first protrusion 21 and the second protrusion 22, so as to limit the limiting member 2 in the first direction and the second direction, thereby limiting the cable 1.

[0077] Optionally, a transition fit may be provided between the inner circumference of the limiting structure and the connecting portion 20. In this way, the connecting portion 20 may be prevented from scratching the housing 02 of the electrical appliance.

[0078] In one example, see Figure 5 The limiting member 2 is a structure with a concave middle portion and two raised ends, the two raised ends are respectively the first protruding portion 21 and the second protruding portion 22, the concave portion is the connecting portion 20, the connecting portion 20 is sleeved outside the cable 1 and is fixedly connected to the cable 1, the first protruding portion 21 and the second protruding portion 22 both have a frustum-shaped structure, and the top of the frustum-shaped structure is connected to the connecting portion 20. Furthermore, the first protruding portion 21 and the second protruding portion 22 have two oppositely arranged conical surfaces, which are respectively abutted against two oppositely-separated wall surfaces of the limiting structure to limit the cable 1.

[0079] In some examples, the first protrusion 21 and the second protrusion 22 may both have a block structure (not shown). The first protrusion 21 and the second protrusion 22 are both located outside the connecting portion 20. Optionally, the first protrusion 21 and the second protrusion 22 are arranged opposite to each other.

[0080] In some examples, the first protrusion 21 and the second protrusion 22 are both annular protrusion structures.

[0081] like Figure 2 As shown, the first protrusion 21 and the second protrusion 22 are both annular protrusion structures located at both ends of the stopper 2, and the first protrusion 21 and the second protrusion 22 are both annular protrusion structures, and the first protrusion 21 and the second protrusion 22 are arranged in parallel. In this way, it can be ensured that when the cable 1 rotates circumferentially, the first protrusion 21 and the second protrusion 22 can always cooperate with the housing 02 of the electrical appliance.

[0082] In some possible embodiments, at least one of the connecting portion 20, the first protrusion 21, and the second protrusion 22 in the limiting member 2 has a rotation limiting structure 100, and the rotation limiting structure 100 is used to cooperate with the housing 02 of the electrical appliance to limit the circumferential rotation of the cable 1.

[0083] It is easy to understand that if the cable 1 rotates in the circumferential direction, the end of the cable 1 and the charging terminal may be worn, resulting in failure of the electrical connection between the charging pile and the electric gun. Correspondingly, for other electrical appliances, if the cable 1 rotates in the circumferential direction, the ends of the cable 1 may be worn between the electrical appliances, resulting in damage to the electrical appliances.

[0084] The rotation limiting structure 100 means that at least one of the connecting portion 20, the first protruding portion 21 and the second protruding portion 22 is a non-rotating structure. The so-called non-rotating structure means that during the rotation along any rotation axis, the outer wall surface of the component will fluctuate.

[0085] For some examples, see Figure 2 , the connection part 20 has a rotation limiting structure 100. Specifically, the connection part 20 may have a prism-shaped structure, and illustratively, the connection part 20 may be a hexagonal prism-shaped structure. For the molding steps of the connection part 20, reference may be made to the above introduction, which will not be repeated here.

[0086] Optionally, the above-mentioned rotation limiting structure 100 can be one or more of a limiting plane, a limiting groove or a limiting convex beam. Referring to the previous example, when the connection portion 20 has a prismatic structure, the connection portion 20 has a plurality of limiting planes, and the specific number of the limiting planes is related to the specific structure of the connection portion 20. For example, when the connection portion 20 has a hexagonal prism structure, the connection portion 20 has six limiting planes. It is easy to understand that when the rotation limiting structure 100 is a limiting convex beam, a corresponding position on the housing 02 of the electrical appliance is provided with a slot structure or a protrusion structure that is compatible with the limiting convex beam, and when the rotation limiting structure 100 is a limiting groove, a corresponding position on the housing 02 of the electrical appliance is provided with a protrusion structure that is compatible with the limiting convex beam.

[0087] Furthermore, in order to improve the rotation limiting ability of the limit member 2, the limit member 2 may have a plurality of rotation limiting structures 100, and the plurality of rotation limiting structures 100 may be arranged on different parts of the limit member 2, such as a plurality of rotation limiting structures 100 arranged on at least two of the connecting portion 20, the first protruding portion 21 and the second protruding portion 22. Accordingly, the types of the plurality of rotation limiting structures 100 may be the same or different. For example, the connecting portion 20 and the first protruding portion 21 of the limit member 2 respectively have a rotation limiting structure 100, wherein the rotation limiting structure 100 on the connecting portion 20 is a limiting plane, and the rotation limiting structure 100 on the first protruding portion 21 is a limiting convex beam.

[0088] In some possible embodiments, the cable assembly 01 further includes a wire sheath 3 .

[0089] like Figure 7As shown, the wire protection sleeve 3 is located outside the limiting member 2 and is fixedly connected to the limiting member 2 .

[0090] Specifically, the wire protection sleeve 3 can be formed on the outside of the limiter 2 by injection molding, see Figure 7 The cable sheath 3 has a first accommodating cavity, a second accommodating cavity and a third accommodating cavity which are connected in sequence. The first accommodating cavity and the third accommodating cavity are respectively used to accommodate part of the cable 1, and the second accommodating cavity is used to accommodate the limiter 2, so that the cable sheath 3 completely covers the limiter 2. Further, referring to the above description, in some examples, at least part of the connecting portion 20 is recessed in the direction close to the cable 1 so that the connecting portion 20 and the cable 1 have an interference fit. In this process, the two ends of the limiter 2 are raised to form a first protrusion 21 and a second protrusion 22. The first protrusion 21 and the second protrusion 22 have gaps with the outer peripheral wall of the cable 1, respectively. The cable sheath 3 is molded on the outside of the limiter 2 by an injection molding process, which can prevent the limiter 2 from scratching the cable 1.

[0091] In some possible embodiments, the limiting member 2 limits the movement of the cable 1 in the extension direction by cooperating between the cable sheath 3 and the housing 02 of the electrical appliance. Figure 7 and Fig.10 The cable sheath 3 is injection molded outside the stopper 2, and the first protrusion 21 and the second protrusion 22 of the stopper 2 are used to limit the movement of the cable sheath 3 in the extension direction of the cable 1. Fig.11 The outer wall of the wire sheath 3 has two parallel annular protrusion structures, which are distributed on both sides of the limiting protrusion in the housing 02 of the electrical appliance. The adjacent wall surfaces of the two annular protrusion structures on the outer wall of the wire sheath 3 respectively abut against the wall surfaces opposite to the limiting protrusion, so that the limiting member 2 limits the movement of the cable 1 in the extension direction through the wire sheath 3.

[0092] In this way, the limiting member 2 can be prevented from directly contacting the housing 02 of the electrical appliance, thereby preventing the limiting member 2 from scratching the housing 02 of the electrical appliance.

[0093] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0094] The disclosed embodiment provides a cable assembly 01, in which the limiter 2 includes a connecting portion 20, a first protruding portion 21, and a second protruding portion 22. The connecting portion 20 is sleeved outside the cable 1 and fixedly connected to the cable 1. The first protruding portion 21 and the second protruding portion 22 are spaced apart in the extension direction of the cable 1 and are respectively connected to the connecting portion 20. The first protruding portion 21 and the second protruding portion 22 are used to cooperate with the housing 02 of the electrical appliance to limit the movement of the cable 1 in the extension direction. In this way, by adding the limiter 2, the connection between the cable assembly 01 and the electrical appliance (electric gun) is no longer solely dependent on the cable 1 and the charging terminal in the electric gun, thereby improving the connection reliability between the cable assembly 01 and the electric gun. Therefore, when the user grasps the cable assembly 01 to plug and unplug the electric gun, the electrical connection between the cable assembly 01 and the electric gun is not easy to fail.

[0095] The embodiment of the present disclosure also provides an electrical appliance, which includes the above-mentioned cable assembly 01 and housing 02. Figure 3 As shown, the housing 02 has a first limiting structure 021 , and the first limiting structure 021 cooperates with the first protruding portion 21 and the second protruding portion 22 to limit the movement of the cable 1 in the extension direction.

[0096] By adopting the technical solution provided in the embodiment of the present disclosure, a first limiting structure 021 cooperating with the limiting member 2 is provided on the shell 02 to limit the movement of the limiting member 2. Since the limiting member 2 is fixedly connected to the outside of the cable 1, the movement of the cable 1 in its extension direction can be limited by the first limiting structure 021, thereby avoiding failure of the electrical connection between the cable 1 and the electrical appliance.

[0097] Specifically, see Figure 3 The housing 02 includes a first shell portion 0201 and a second shell portion 0202 , and the first shell portion 0201 and the second shell portion 0202 are connected to form a cylindrical structure, and the cylindrical structure accommodates the above-mentioned limit member 2 and part of the cable 1 .

[0098] In the following, unless otherwise specified, the structures of the first shell portion 0201 and the second shell portion 0202 are completely the same.

[0099] In some possible embodiments, the first limiting structure 021 cooperates with opposite wall surfaces of the first protruding portion 21 and the second protruding portion 22 , respectively.

[0100] like Figure 3 and Figure 4As shown, the inner side walls of the first shell 0201 and the second shell 0202 are respectively provided with a first limiting structure 021, each of which includes a first protruding structure 021a and a second protruding structure 021b, and the first protruding structure 021a is located on the side of the first protruding portion 21 away from the second protruding portion 22, and is connected to the first protruding portion 21. Specifically, the first protruding structure 021a is a semicircular ring plate-shaped structure, which is arranged parallel to the first protruding portion 21 in the form of an annular protruding structure, and the wall surface of the first protruding structure 021a close to the second protruding structure 021b is against the wall surface of the first protruding portion 21 away from the second protruding portion 22.

[0101] Correspondingly, the second protrusion structure 021b is located on the side of the second protrusion 22 away from the first protrusion 21, and is connected to the second protrusion 22. Specifically, the second protrusion structure 021b is a semi-circular ring plate structure, which is arranged parallel to the second protrusion 22 which is an annular protrusion structure. The wall surface of the second protrusion structure 021b close to the first protrusion structure 021a is against the wall surface of the second protrusion 22 away from the first protrusion 21.

[0102] There is a clearance fit between the inner wall of the semicircular plate-shaped structure and the outer wall of the cable 1 , so that scratches between the housing 02 and the cable 1 can be avoided.

[0103] Exemplarily, the first limiting structure 021 and the first shell portion 0201 , as well as the first limiting structure 021 and the second shell portion 0202 can be integrally formed by an injection molding process.

[0104] In some possible embodiments, the first limiting structure 021 cooperates with opposite wall surfaces of the first protruding portion 21 and the second protruding portion 22 .

[0105] like Figure 5 and Figure 6 As shown, the first limiting structure 021 includes a third protruding structure 021c, and the third protruding structure 021c is located between the first protruding portion 21 and the second protruding portion 22, and is connected to the first protruding portion 21 and the second protruding portion 22 respectively.

[0106] Specifically, the first protruding structure 021a is a plate-shaped structure and is arranged parallel to the first protruding portion 21 which is an annular protruding structure. The wall surface of the first protruding structure 021a close to the second protruding structure 021b abuts against the wall surface of the first protruding portion 21 away from the second protruding portion 22.

[0107] Correspondingly, the third protrusion structure 021c is an annular protrusion, and the third protrusion structure 021c is coaxially arranged with the first protrusion 21 and the second protrusion 22 of the annular protrusion structure, and the two opposite walls of the third protrusion structure 021c are respectively against the two opposite walls of the first protrusion 21 and the second protrusion structure 021b.

[0108] In some examples, such as Fig.10 and Fig.11 As shown, the outer portion of the stopper 2 is covered with an injection-molded cable sheath 3, and two parallel annular protrusion structures are arranged at intervals on the outer wall of the cable sheath 3. A third protrusion structure 021c is arranged inside the housing 02, and the third protrusion structure 021c is located between the two annular protrusion structures and is connected to the annular protrusion structures respectively. The third protrusion structure 021c limits the movement of the stopper 2 through the cable sheath 3, thereby limiting the movement of the cable 1 in its extension direction.

[0109] For the specific structure of the third protruding structure 021c, reference may be made to the above description, and the embodiments of the present disclosure will not be described in detail here.

[0110] In some possible embodiments, the housing 02 further has a second limiting structure 022 , and the second limiting structure 022 cooperates with the rotation limiting structure 100 of the limiting member 2 to limit the rotation of the cable 1 in the circumferential direction.

[0111] See also Figure 8 , the first shell 0201 has a second limiting structure 022, and the second shell 0202 also has a second limiting structure 022. Figure 8 As shown, the second limiting structure 022 has a plate-like structure having a first slot 022 a , which is adapted to the rotation limiting structure 100 on the limiting member 2 and is used to be engaged with the rotation limiting structure 100 on the limiting member 2 .

[0112] In some examples, such as Fig. 9 As shown, the connecting part 20 is a hexagonal columnar structure. In this example, a accommodating cavity with a hexagonal cross-section is formed between the first slots 022a of the two second limiting structures 022 on the first shell part 0201 and the second shell part 0202. The accommodating cavity accommodates the connecting part 20 and limits the circumferential rotation of the connecting part 20.

[0113] Optionally, the second limiting structure 022 may include a plurality of limiting plates, which are evenly spaced along the extension direction of the cable 1, and each limiting plate has one of the first slots 022a. In this way, the load generated when the limiting member 2 rotates can be evenly distributed, thereby improving the service life of the housing 02.

[0114] It is understandable that the second limiting structure 022 can also be a limiting protrusion, a limiting groove, a limiting plane or other structures. The specific type of the second limiting structure 022 can be set according to the rotation limiting structure 100 on the limiting member 2, and the embodiment of the present disclosure does not limit this.

[0115] In some possible embodiments, Fig.12 As shown, a relief hole 023 is formed between the first shell 0201 and the second shell 0202. At the relief hole 023, the wall thickness of the first shell 0201 and the second shell is the same, and both are equal to the distance between the two annular protrusions on the cable sheath 3. The aperture of the relief hole 023 is equal to the outer diameter of the portion between the two annular protrusions on the cable sheath 3. In this way, the movement of the stopper 2 can be restricted by the cooperation between the relief hole 023 and the two annular protrusions on the cable sheath 3, thereby limiting the movement of the cable 1 in its extension direction.

[0116] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.
