[0052] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0053] The following is for reference. Figures 1-14 Description of a charging gun 100 according to an embodiment of the present utility model.

[0054] like Figures 1-10 As shown, the charging gun 100 according to an embodiment of the present utility model includes: a housing 10, a cable 20, and a sealing ring 30.

[0055] The housing 10 has a mounting cavity 101, and the housing 10 forms a through hole 121 communicating with the mounting cavity 101; the cable 20 includes a wire harness assembly 21 and an overmolded part 22 wrapped around the outside of the wire harness assembly 21. The overmolded part 22 includes a mating section 221 that passes through the through hole 121 and extends into the mounting cavity 101. The mating section 221 forms a sealing platform 2211 that extends in an annular shape along the circumference of the cable 20; the sealing ring 30 is sleeved on the sealing platform 2211 and seals against the sealing platform 2211 and the inner wall of the mounting cavity 101.

[0056] In some specific examples, such as Figures 1-4 As shown, one end of the cable 20 is connected to the housing 10. Further, the end of the cable 20 connected to the housing 10 has a through hole 121 extending through the housing 10 along its thickness direction. The through hole 121 is circular, and the mating section 221 of the overmolded component 22 passes through the through hole 121 and extends into the mounting cavity 101 of the housing 10. In some specific examples, such as... Figure 9 and Figure 10 As shown, the charging gun 100 also includes a gun head 40, and the housing 10 has a first opening 111, with the gun head 40 covering the first opening 111.

[0057] In some specific examples, such as Figures 4-8As shown, a sealing platform 2211 extending in an annular shape along the circumference of the cable 20 is formed on the outer peripheral surface of the mating section 221. The inner peripheral surface of the sealing ring 30 seals against the outer end of the sealing platform 2211 in the radial direction of the cable 20, and the outer peripheral surface of the sealing ring 30 seals against the inner wall of the mounting cavity 101. In other words, the sealing ring 30 seals against the sealing platform 2211 and the inner wall of the mounting cavity 101, thereby achieving a seal at the tail of the charging gun 100.

[0058] In some specific examples, the sealing platform 2211 and the mating section 221 are integrally molded, thereby ensuring the structural strength of the connection between the sealing platform 2211 and the mating section 221 and effectively reducing assembly difficulty. In some specific examples, both the sealing platform 2211 and the mating section 221 are made of TPE material.

[0059] It should be noted that TPE material is a thermoplastic elastomer, which possesses excellent elasticity, thereby effectively improving the sealing effect of the sealing plate 2211. Furthermore, thermoplastic elastomers have good chemical resistance, exhibiting good resistance to various chemicals and maintaining stable performance under different environments. This effectively improves the durability and stability of the sealing plate 2211 and the mating section 221.

[0060] In this embodiment, the sealing ring 30 is sealed against the inner wall of the sealing platform 2211 and the mounting cavity 101. That is, there are no gaps between the sealing ring 30 and the sealing platform 2211, and between the sealing ring 30 and the inner wall of the mounting cavity 101. This increases the sealing performance of the charging gun 100 and effectively prevents moisture and dust from the external environment from entering the charging gun 100 during use, thereby effectively reducing the risk of damage to the charging gun 100 caused by the external environment.

[0061] According to the embodiment of the present invention, the charging gun 100 includes a housing 10, a cable 20, and a sealing ring 30. The housing 10 has a mounting cavity 101 and a through hole 121 communicating with the mounting cavity 101. The cable 20 includes a wire harness assembly 21 and an overmolded part 22 wrapped around the outside of the wire harness assembly 21. The overmolded part 22 includes a mating section 221 that passes through the through hole 121 and extends into the mounting cavity 101. The mating section 221 forms a sealing platform 2211 that extends in an annular shape along the circumference of the cable 20. The sealing ring 30 is sleeved on the sealing platform 2211 and seals against the inner wall of the mounting cavity 101. This effectively improves the sealing effect of the charging gun 100 and thus effectively enhances the reliability of the charging gun 100.

[0062] In some specific examples, such as Figure 4As shown, a groove 22111 extending in an annular direction along the circumference of the cable 20 is formed on the outer peripheral surface of the sealing platform 2211, and the sealing ring 30 is disposed in the groove 22111.

[0063] For example Figure 4 As shown, a groove 22111 is formed on the outer peripheral surface of the sealing platform 2211, which is recessed from the outside to the inside along the radial direction of the cable 20. The sealing ring 30 is embedded in the groove 22111, that is, the sealing ring 30 is firmly fixed in the groove 22111, thereby effectively preventing the sealing ring 30 from shifting during assembly or use, and thus ensuring long-term stable sealing performance.

[0064] In this embodiment, by forming a groove 22111 extending in an annular direction along the circumference of the cable 20 on the outer peripheral surface of the sealing platform 2211, and the sealing ring 30 is disposed in the groove 22111, the stability of the sealing ring 30 can be effectively improved, thereby effectively enhancing the sealing effect of the sealing ring 30.

[0065] In some specific examples, the sealing platform 2211 is provided with a reinforcement that extends in a ring shape along the circumference of the sealing platform 2211.

[0066] It should be noted that the ring-shaped reinforcing member extending circumferentially along the sealing platform 2211 can effectively increase the structural strength and rigidity of the sealing platform 2211, prevent excessive deformation of the sealing platform 2211 due to external forces during installation or use, and thus ensure a long-term stable sealing effect.

[0067] This embodiment provides a reinforcing member in the sealing platform 2211, and the reinforcing member extends in a ring shape along the circumference of the sealing platform 2211. This effectively increases the structural strength and rigidity of the sealing platform 2211, reduces the deformation of the sealing platform 2211 caused by external forces, thereby effectively improving the stability of the sealing platform 2211 and ensuring the long-term reliable sealing effect of the sealing platform 2211.

[0068] In some specific examples, the reinforcement is a metal part and is embedded in the sealing platform 2211.

[0069] This embodiment uses a metal reinforcement component embedded in the sealing platform 2211, which not only effectively reduces production costs but also saves installation space.

[0070] In some specific examples, such as Figure 4 As shown, the sealing ring 30 is a multi-tooth sealing ring.

[0071] It should be noted that the multiple sealing lips of the multi-tooth sealing ring provide multi-layered sealing protection, thereby more effectively preventing moisture, dust, and other contaminants from entering the charging gun 100. Furthermore, the multi-tooth design of the sealing ring effectively increases the friction between the sealing ring 30 and the contact surface, thus helping to reduce the risk of the sealing ring 30 slipping or shifting during use, and consequently effectively improving the stability and reliability of the sealing ring 30.

[0072] In this embodiment, by setting the sealing ring 30 as a multi-tooth sealing ring, not only can the sealing effect of the sealing ring 30 be effectively improved, but also the stability and reliability of the sealing ring 30 can be effectively improved.

[0073] In some specific examples, such as Figure 6 and Figure 8 As shown, a boss portion 112 with a protrusion 1231 is formed on the inner wall of the housing 10. The boss portion 112 extends in a ring shape along the circumference of the cable 20, and the radial outer end of the sealing ring 30 seals against the boss portion 112.

[0074] In some specific examples, such as Figure 6 and Figure 8 As shown, a boss portion 112 is formed on the inner wall of the housing 10, which protrudes radially inward along the cable 20. Further, the boss portion 112 extends in a ring shape along the circumference of the cable 20. A sealing ring 30 is embedded in the groove 22111, and the outer end of the sealing ring 30 in the radial direction of the cable 20 seals against the boss portion 112.

[0075] In this embodiment, a boss portion 112 with a protrusion 1231 is formed on the inner wall of the housing 10. The boss portion 112 extends in a ring shape along the circumference of the cable 20. The radial outer end of the sealing ring 30 seals against the boss portion 112. This not only effectively increases the structural strength of the housing 10, thereby effectively improving the durability of the housing 10, but also effectively absorbs the manufacturing error of the sealing ring 30, thereby further ensuring the sealing effect of the sealing ring 30.

[0076] In some specific examples, such as Figures 9-12 As shown, the housing 10 includes a main housing 11 and a rear cover 12. The main housing 11 is open at one end along the axial direction of the cable 20. The rear cover 12 covers the open side of the main housing 11 and cooperates with the main housing 11 to define a mounting cavity 101. A through hole 121 is formed in the rear cover 12 and passes through the rear cover 12 along the axial direction of the cable 20. It should be noted that in some specific examples, the axial direction of the cable 20 is the direction shown as A-A' in the figure.

[0077] In this embodiment, a main shell 11 and a rear cover 12 are provided in the housing 10. The main shell 11 is open at one end along the axial direction of the cable 20. The rear cover 12 covers the open side of the main shell 11 and cooperates with the main shell 11 to define the mounting cavity 101. A through hole 121 is formed in the rear cover 12 and passes through the rear cover 12 along the axial direction of the cable 20. This facilitates the later maintenance of the charging gun 100 and effectively improves the convenience of maintenance.

[0078] In some specific examples, such as Figure 6 and Figure 8 As shown, the main shell 11 and the rear cover 12 are snap-fitted together.

[0079] It should be noted that snap-fit ​​connections typically do not require additional tools or fasteners, thus making the assembly process simpler and faster. Furthermore, snap-fit ​​connections effectively ensure a tight fit between the main housing 11 and the rear cover 12, reducing the risk of the rear cover 12 accidentally detaching during normal use.

[0080] This embodiment sets the connection between the main shell 11 and the rear cover 12 as a snap-fit ​​connection, which not only effectively simplifies the connection between the main shell 11 and the rear cover 12, but also effectively improves the stability and reliability of the connection between the main shell 11 and the rear cover 12.

[0081] In some specific examples, such as Figure 10 and Figure 12 As shown, the rear cover 12 is provided with a plurality of first hooks 122, and the main shell 11 is provided with a plurality of first slots 113, with the first hooks 122 and the first slots 113 corresponding to each other.

[0082] For example, the number of the first hook 122 can be two, three, four, five, or more than six. In some specific examples, such as Figure 12 As shown, there are four first hooks 122. Multiple first hooks 122 are set at one end of the rear cover 12 facing the main shell 11, and multiple first hooks 122 are arranged at intervals along the circumference of the cable 20. The first slots 113 on the main shell 11 correspond to and cooperate with the first hooks 122 one by one.

[0083] In this embodiment, multiple first hooks 122 are provided on the rear cover 12 and multiple first slots 113 are provided on the main shell 11. The first hooks 122 and the first slots 113 are matched one-to-one, which can effectively avoid the risk of excessive force on a single first hook 122, thereby effectively reducing the possibility of damage to the first hook 122 and thus effectively improving the reliability of the first hook 122.

[0084] In some specific examples, such as Figure 9 and Figure 10As shown, a first slot 113 is formed on the inner wall of the main housing 11. A guide groove 114 extending along the axial direction of the cable 20 is also formed on the inner wall of the main housing 11. One end of the guide groove 114 is connected to the first slot 113, and the other end of the guide groove 114 passes through the end face of the main housing 11 facing the rear cover 12.

[0085] In some specific examples, such as Figure 9 and Figure 10 As shown, the first slot 113 is located on the side of the guide groove 114 opposite to the rear cover 12. The guide groove 114 extends circumferentially along the cable 20, and one end of the guide groove 114 is connected to the first slot 113. The other end of the guide groove 114 passes through the end face of the main shell 11 facing the rear cover 12. When assembling the rear cover 12 onto the main shell 11, the multiple first hooks 122 are first aligned with the multiple guide grooves 114 in the axial direction of the cable 20, and then the first hooks 122 are engaged in the first slot 113 through the guide groove 114.

[0086] In this embodiment, a first slot 113 is formed on the inner wall of the main housing 11, and a guide groove 114 extending along the axial direction of the cable 20 is formed on the inner wall of the main housing 11. One end of the guide groove 114 is connected to the first slot 113, and the other end of the guide groove 114 passes through the end face of the main housing 11 facing the rear cover 12. This can effectively reduce the assembly difficulty of the rear cover 12 and thus effectively improve the assembly convenience of the rear cover 12.

[0087] In some specific examples, such as Figure 13 and Figure 14 As shown, the rear cover 12 is provided with a limiting plate 123 extending toward the main shell 11, and the limiting plate 123 abuts against the sealing platform 2211 in the axial direction of the cable 20.

[0088] It should be noted that the limiting plate 123 provides additional support for the sealing stage 2211, preventing it from moving towards the rear cover 12, thereby ensuring that the sealing stage 2211 remains in the correct position inside the charging gun 100. Furthermore, the limiting plate 123 facilitates quick positioning of the sealing stage 2211, making the assembly process simpler and more efficient.

[0089] In this embodiment, a limiting plate 123 extending toward the main housing 11 is provided on the rear cover 12. The limiting plate 123 abuts against the sealing platform 2211 in the axial direction of the cable 20, which can effectively fix the sealing platform 2211 and reduce the possibility of movement of the sealing platform 2211, thereby further ensuring the sealing effect. In addition, it can also effectively improve the assembly efficiency of the charging gun 100.

[0090] In some specific examples, such as Figure 12As shown, a protrusion 1231 is formed on the end face of the limiting plate 123 facing the main shell 11, and the limiting plate 123 abuts against the sealing platform 2211 through the protrusion 1231.

[0091] It should be noted that the area of ​​the end face of the protrusion 1231 facing away from the limiting plate 123 is smaller than the area of ​​the end face of the limiting plate 123 facing the main shell 11. This can effectively increase the stress between the protrusion 1231 and the sealing platform 2211, thereby effectively reducing the assembly difficulty of the rear cover 12.

[0092] In this embodiment, a protrusion 1231 is formed on one end face of the limiting plate 123 facing the main shell 11. The limiting plate 123 abuts against the sealing platform 2211 through the protrusion 1231, which can effectively reduce the assembly difficulty of the rear cover 12 and thus effectively improve the assembly convenience of the rear cover 12.

[0093] In some specific examples, such as Figure 12 As shown, the limiting plate 123 extends radially along the cable 20, and there are multiple limiting plates 123, which are arranged at intervals along the circumference of the cable 20.

[0094] For example, the number of limit plates 123 can be two, three, four, five, or more than six. In some specific examples, such as Figure 12 As shown, there are eight limiting plates 123, and the multiple limiting plates 123 are arranged at intervals along the circumference of the cable 20.

[0095] In this embodiment, by extending the limiting plate 123 radially along the cable 20, and having multiple limiting plates 123 arranged at intervals along the circumference of the cable 20, it is possible to avoid damage to a single limiting plate 123 due to excessive force, thereby effectively protecting the limiting plate 123 and improving its reliability.

[0096] In some specific examples, such as Figure 12 As shown, the rear cover 12 is provided with a support plate 124 that extends in a ring shape along the circumference of the cable 20, and multiple limiting plates 123 are connected to the support plate 124.

[0097] In some specific examples, such as Figure 12 As shown, a support plate 124 extending in an annular shape along the circumference of the cable 20 is formed at one end of the rear cover 12 facing the main shell 11. Furthermore, the outer end of the limiting plate 123 in the radial direction of the cable 20 is connected to the support plate 124, and the end face of the support plate 124 facing the main shell 11 is flush with the end face of the protrusion 1231 facing the main shell 11 in the axial direction of the cable 20.

[0098] In this embodiment, a support plate 124 extending in a ring shape along the circumference of the cable 20 is provided on the back cover 12, and multiple limiting plates 123 are connected to the support plate 124, which can effectively improve the structural strength and rigidity of the back cover 12, thereby effectively improving the durability and reliability of the back cover 12.

[0099] In some specific examples, such as Figure 4 and Figure 12 As shown, a first limiting part 2212 is formed on the mating section 221, and a second limiting part 125 is formed in the mounting cavity 101. The first limiting part 2212 and the second limiting part 125 are matched to limit the cable 20 from rotating around the housing 10 in the circumferential direction of the cable 20.

[0100] In a specific example, such as Figure 4 As shown, the first limiting part 2212 is disposed on the side of the sealing platform 2211 facing the rear cover 12. Furthermore, the mating section 221 is integrally formed with the first limiting part 2212. The first limiting part 2212 can engage with the second limiting part 125 in the mounting cavity 101 to limit the rotation of the cable 20 relative to the housing 10 along the circumference of the cable 20.

[0101] In this embodiment, the limiting cooperation between the first limiting part 2212 and the second limiting part 125 can effectively restrict the cable 20 from rotating around the housing 10 in the circumferential direction, thereby further improving the fixing effect of the cable 20.

[0102] In some specific examples, such as Figure 4 and Figure 12 As shown, the first limiting part 2212 extends in a ring shape along the circumferential direction of the mating section 221. The outer peripheral surface of the first limiting part 2212 includes at least one limiting plane 22121. The second limiting part 125 extends in a ring shape along the circumferential direction of the through hole 121, and defines a limiting groove 1251 that matches the shape of the first limiting part 2212 on its inner side. The first limiting part 2212 is fitted into the limiting groove 1251.

[0103] For example, the outer peripheral surface of the first limiting portion 2212 may include a limiting plane 22121; or, for instance, the outer peripheral surface of the first limiting portion 2212 may include multiple limiting planes 22121. In some specific examples, such as Figure 12 As shown, the second limiting part 125 extends in a ring shape along the circumference of the through hole 121. Further, the second limiting part 125 extends along the axial direction of the cable 20, and the inner side of the second limiting part 125 defines a limiting groove 1251 that matches the shape of the first limiting part 2212. The first limiting part 2212 can cooperate with the limiting groove 1251 to restrict the cable 20 from rotating relative to the housing 10 along the circumference of the cable 20.

[0104] In this embodiment, the first limiting part 2212 extends into a ring shape along the circumference of the mating section 221. The outer peripheral surface of the first limiting part 2212 includes at least one limiting plane 22121. The second limiting part 125 extends into a ring shape along the circumference of the through hole 121, and defines a limiting groove 1251 that matches the shape of the first limiting part 2212 on its inner side. The first limiting part 2212 fits into the limiting groove 1251, which can effectively utilize the installation space in the mounting cavity 101, thereby effectively improving the compactness of the charging gun 100.

[0105] In some specific examples, such as Figure 4 As shown, the cross-sectional shape of the first limiting part 2212 perpendicular to the axial direction of the cable 20 is polygonal. That is, the first limiting part 2212 has multiple limiting planes 22121, thereby effectively enhancing the limiting effect.

[0106] In this embodiment, by setting the cross-sectional shape of the first limiting part 2212 perpendicular to the axial direction of the cable 20 as a polygon, it can not only effectively simplify the structural construction of the first limiting part 2212, but also effectively improve the fixing effect on the cable 20.

[0107] In some specific examples, such as Figure 4 , Figure 12 , Figure 13 and Figure 14 As shown, the first limiting part 2212 is arranged on the side of the sealing platform 2211 facing the through hole 121. A limiting hook 1252 extending toward the sealing platform 2211 is formed around the periphery of the through hole 121. The hook portion of the limiting hook 1252 abuts against the side surface of the first limiting part 2212 opposite to the through hole 121.

[0108] In this embodiment, by arranging the first limiting part 2212 on the side of the sealing platform 2211 facing the through hole 121, and forming a limiting hook 1252 extending toward the sealing platform 2211 around the through hole 121, the hook portion of the limiting hook 1252 abuts against the side surface of the first limiting part 2212 away from the through hole 121, which can not only effectively optimize the structure of the charging gun 100, but also effectively limit the movement of the cable 20 in its axial direction, thereby further improving the stability of the cable 20.

[0109] In some specific examples, such as Figure 12-14 As shown, there are multiple limit hooks 1252, which are arranged at intervals along the circumference of the through hole 121.

[0110] In this embodiment, the number of limit hooks 1252 is set to multiple. The multiple limit hooks 1252 are arranged at intervals along the circumference of the through hole 121, which can effectively avoid the risk of damage to a single limit hook 1252 due to excessive force, thereby effectively protecting the limit hooks 1252 and thus effectively improving the reliability of the limit hooks 1252.

[0111] In some specific examples, such as Figure 3 As shown, the charging gun 100 also includes a controller 50, which is located inside the mounting cavity 101, and the cable 20 is connected to the controller 50.

[0112] In some specific examples, such as Figure 3 As shown, one end of the cable 20 is connected to the controller 50 by soldering. By placing the controller 50 within the mounting cavity 101, a high degree of device integration is achieved. This not only saves installation space but also simplifies the overall design, making the charging gun 100 more compact and convenient for users.

[0113] In this embodiment, by placing the controller 50 inside the mounting cavity 101 and connecting the cable 20 to the controller 50, not only can the compactness of the charging gun 100 be effectively improved, but the convenience of using the charging gun 100 for the user can also be effectively improved.

[0114] In some specific examples, such as Figure 11 As shown, the rear cover 12 is provided with multiple positioning blind holes 126, which extend through the rear cover 12 along the axial direction of the cable 20. The positioning blind holes 126 facilitate the initial positioning of the rear cover 12 during installation, thereby effectively improving assembly efficiency. The rear cover 12 is also provided with multiple installation process grooves 127, which provide points for applying external force to the equipment during installation of the rear cover 12, facilitating automated assembly.
