Description

Technical Field

[0001] This utility model relates to the field of charging head technology, and in particular to a charging adapter that can be adapted to multiple plugs. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the compatibility issues of charging infrastructure are becoming increasingly prominent. Different brands and models of new energy vehicles have significant differences in the size, shape, internal conductive terminal layout, and spacing of their charging ports (i.e., charging sockets) to meet their respective technical standards or design requirements. This means that the charging guns standardly included with charging stations are often incompatible with the charging ports of various vehicle models, causing great inconvenience to users.

[0003] To address this compatibility challenge, various charging adapters have emerged in the industry. These adapters feature an input connector for connecting to charging stations, an output connector for connecting to vehicle charging ports, and a conductive wire for electrically connecting the two, enabling current transfer between different interfaces. However, to further improve compatibility, existing charging adapters typically include multiple adapters, allowing the output connector to be compatible with the charging ports of more vehicle models by replacing different adapter models.

[0004] However, existing technologies have significant flaws in the splicing structure design of the adapter and output connector, resulting in insufficient splicing stability, which is a key issue restricting their performance. Most adapters and output connectors are spliced ​​using only a simple plug-and-play structure, lacking an effective positioning and locking mechanism. During charging, they are prone to loosening due to slight vehicle movement, external force, or their own weight, leading to poor contact of the conductive connectors. This not only affects charging efficiency but may also cause localized overheating due to excessive contact resistance, posing a safety hazard. Therefore, a charging adapter compatible with multiple sockets is provided to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a charging adapter that can be adapted to multiple sockets to address the shortcomings of the existing technology, thereby solving the technical problem of unstable splicing of the adapter connectors in the existing charging adapters.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A charging adapter that can be adapted to multiple sockets includes an output connector, an input connector, and a conductive wire for electrically connecting the output connector and the input connector, and also includes an adapter for splicing with the output connector to make it compatible with a charging port. The output connector includes a plug, and the adapter connector includes a splicing connector; the plug has splicing grooves formed on both the left and right sides, and the splicing connector has splicing parts formed on both the left and right sides that can be inserted into the splicing grooves. Each splicing groove has a snap-fit ​​protrusion formed in it, and the sides of the two splicing parts that are close to each other have snap-fit ​​grooves for the snap-fit ​​protrusions to snap into.

[0007] Furthermore, a first insertion cavity is formed on the front side of the plug, and a first tongue is provided in the first insertion cavity, with an end extending to the outside of the first tongue. A plurality of first sockets are formed on the end of the first tongue extending to the outside of the first insertion cavity, and a first conductive connector for electrically connecting with a conductive wire is provided in each first socket.

[0008] Furthermore, a second insertion cavity is formed on the front side of the splice joint, and a second tongue is provided in the second insertion cavity, with an end extending to the outside of the second tongue. Several second insertion holes are formed on the end of the second tongue extending to the outside of the second insertion cavity, and a second conductive connector is provided in each second insertion hole. The splice has a plug portion for insertion into the first plug cavity on the side away from the second tongue. The plug portion is formed with a slot for the first tongue to be inserted, and a plug terminal for electrical connection with the second conductive connector is installed in the slot. When the first tongue is inserted into the slot, the plug terminal is inserted into the first socket and contacts the first conductive connector.

[0009] Furthermore, both the first conductive connector and the second conductive connector can be copper tubes or copper sheets.

[0010] Furthermore, the top and bottom of the connector are formed with extensions extending to the upper and lower parts of the plug, respectively. An insert is provided on the side of the extensions that are close to each other, and the top and bottom surfaces of the plug are formed with grooves for the inserts to be inserted.

[0011] Furthermore, each insert has a second bevel formed on its end away from the second tongue for guidance.

[0012] Furthermore, the top and bottom surfaces of the plug are both formed with limiting grooves, and the upper and lower extensions are each equipped with limiting parts for engaging into different limiting grooves.

[0013] Furthermore, the limiting portion includes a sliding cavity formed within the extension portion, a sliding member is slidably disposed within the sliding cavity, the sliding member is provided with a limiting member for engaging with the limiting groove, the end of the limiting member near the insertion portion is hemispherical, and the end extends to the outside of the limiting portion; a spring is provided within the sliding cavity for applying a pushing force toward the insertion portion to the sliding member.

[0014] Furthermore, the front edge of the top surface of the plug and the front edge of the bottom surface are both formed with a first bevel for guiding the hemispherical end of the limiting member.

[0015] The beneficial effects of this utility model are as follows: When the charging port model on a new energy vehicle is incompatible with the charging gun model on a charging pile, the input connector is first plugged into the charging gun on the charging pile, and then the corresponding output connector is plugged into the charging port on the new energy vehicle, so that the charging gun can connect to the charging port for charging, thus achieving charging conversion. However, when the output connector is incompatible with the charging port on another new energy vehicle, an adapter connector compatible with the charging port on that new energy vehicle can be attached to the output connector, and then the adapter connector is plugged into the charging port on that new energy vehicle. With the help of the adapter connector, the output connector can be compatible with different charging ports; furthermore, the model and type of the adapter connector attached to the output connector can be adapted according to the new energy vehicle to be charged, making this charging adapter compatible with multiple charging ports (i.e., sockets).

[0016] In addition, after inserting the splicing part on the plug into the splicing groove of the splicing connector, the snap-fit ​​protrusion snaps into the corresponding snap-fit ​​groove to improve the stability of the splicing connector and plug after splicing. Attached Figure Description

[0024] The following is a detailed description of a charging adapter that can be adapted to multiple sockets, with reference to the accompanying drawings.

[0025] like Figure 1 As shown, an embodiment of this utility model of a charging adapter compatible with multiple sockets includes an output connector 1, an input connector 3, and a conductive wire 2 for electrically connecting the output connector 1 and the input connector 3. It also includes an adapter 4 for splicing with the output connector 1 to adapt it to a charging port. The output connector 1 and the adapter 4 can independently adapt to different models of charging ports on new energy vehicles; the input connector 3 can connect to the charging head on a charging pile.

[0026] When the charging port model on a new energy vehicle is incompatible with the charging gun model on a charging pile, first connect the input connector 3 to the charging gun on the charging pile, then connect the corresponding output connector 1 to the charging port on the new energy vehicle. This allows the charging gun to connect to the vehicle's charging port via the output connector 1 and the input connector 3, achieving charging adapter functionality. If the output connector 1 is incompatible with the charging port on another new energy vehicle, attach the adapter 4, which is compatible with the charging port on that new energy vehicle, to the output connector 1, and then connect the adapter 4 to the charging port on that new energy vehicle. The adapter 4 allows the output connector 1 to be compatible with different charging ports. The model and type of the adapter 4 attached to the output connector 1 can be adapted according to the new energy vehicle to be charged, enabling this charging adapter to be compatible with multiple charging ports (i.e., sockets).

[0027] like Figure 2-4As shown, the output connector 1 includes a plug 11 and a first insertion cavity 12 formed on the front side of the plug 11. The plug 11 is an insulated plastic plug. The first insertion cavity 12 is provided with a first tongue 13 extending to its outer side. The first tongue 13 is used to insert into the charging port to achieve insertion. A plurality of first sockets 14 are formed on the end of the first tongue 13 extending to the outer side of the first insertion cavity 12. Each first socket 14 is provided with a first conductive connector 15 for electrical connection with the conductive wire 2. The first conductive connector 15 can be a copper tube or a copper sheet. When the plug 11 is inserted into the charging port, the first conductive connector 15 contacts the charging terminal in the charging port to form a current path to achieve charging.

[0028] In this embodiment, the adapter 4 includes a splice 41 and a second plug cavity 42 formed on the front side of the splice 41. The splice 41 is also an insulated plastic plug. The second plug cavity 42 is provided with a second tongue 43 extending to its outer side. The function of the second tongue 43 is the same as that of the first tongue 13, both used to be inserted into the charging port to achieve plugging. A plurality of second sockets 44 are formed on the end of the second tongue 43 extending to the outer side of the second plug cavity 42. Each second socket 44 is provided with a second conductive connector 45. The second conductive connector 45 is also a copper tube or copper sheet. The spacing between the second sockets 44 is greater than or less than the spacing between the first sockets 14. The diameter of the second sockets 44 is greater than or less than the diameter of the first sockets 14, so that the adapter 4 can be adapted to a variety of charging ports.

[0029] Additionally, a plug-in portion 46 for insertion into the first plug cavity 12 is provided on the side of the splice 41 away from the second tongue 43. The plug-in portion 46 is formed with a slot 47 for the first tongue 13 to be inserted into, and a plug-in terminal 48 for electrical connection with the second conductive connector 45 is installed in the slot 47. When the first tongue 13 is inserted into the slot 47, the plug-in portion 46 is inserted into the first plug cavity 12, and the plug-in terminal 48 is inserted into the first socket 14 and contacts the first conductive connector 15, thereby realizing the splicing of the output connector 1 and the adapter connector 4.

[0030] To make the splicing joint 41 and plug 11 more stable after splicing, splicing grooves 16 are formed on both the left and right sides of plug 11, and splicing parts 49 that can be inserted into the splicing grooves 16 are formed on both the left and right sides of splicing joint 41. Each splicing groove 16 has a snap-fit ​​protrusion 17 formed in it, and each side of the splicing parts 49 that is close to each other has a snap-fit ​​groove 410 for the snap-fit ​​protrusion 17 to snap into. After the splicing part 49 is inserted into the splicing groove 16, the snap-fit ​​protrusion 17 snaps into the corresponding snap-fit ​​groove 410 to improve the stability of splicing joint 41 and plug 11 after splicing.

[0031] In addition, the top and bottom of the connector 41 are formed with extensions 411 extending above and below the plug 46, respectively. The sides of the extensions 411 that are close to each other are provided with inserts 412. The top and bottom surfaces of the plug 11 are formed with grooves 18 for inserts 412 to be inserted. During the splicing process of the connector 41 and the plug 11, the inserts 412 are first aligned with the grooves 18, and then force is applied to the connector 41. The inserts 412 are gradually inserted into the grooves 18. After they are fully inserted, the first tongue 13 is automatically aligned with the slot 47 and inserted into it. Under the action of the grooves 18 and the inserts 412, the convenience of splicing the connector 41 and the plug 11 is improved.

[0032] Each insert 412 has a second bevel 413 formed on the end away from the second tongue 43 for guidance. Under the guidance of the second bevel 413, the insert 412 can be inserted into the groove 18 without precise alignment, which improves the accuracy of splicing the connector 41 and the plug 11.

[0033] Limiting grooves 19 are formed on both the top and bottom surfaces of the plug 11, and limiting parts 414 for engaging into different limiting grooves 19 are installed on the upper and lower extensions 411. When the splice 41 is spliced ​​with the plug 11, the upper extension 411 of the splice 41 is positioned above the plug 11, and the limiting part 414 on the extension 411 engages into the limiting groove 19 on the top surface of the plug 11. The lower extension 411 of the splice 41 is positioned below the plug 11, and the limiting part 414 on the extension 411 engages into the limiting groove 19 on the bottom surface of the plug 11.

[0034] like Figure 5 As shown, the limiting portion 414 includes a sliding chamber 4141 formed in the extension portion 411. A sliding member 4142 is slidably disposed in the sliding chamber 4141. The sliding member 4142 is provided with a limiting member 4143 for engaging with the limiting groove 19. The end of the limiting member 4143 near the insertion portion 46 is hemispherical and extends to the outside of the limiting portion 414. A spring 4144 is provided in the sliding chamber 4141 for applying a pushing force to the sliding member 4142 toward the insertion portion 46. During the splicing process of the connector 41 and the plug 11, the hemispherical end of the limiting member 4143 slides on the top surface of the plug 11. At this time, the spring 4144 is in a compressed state. When the limiting member 4143 slides and aligns with the limiting groove 19, under the action of the compressed spring 4144, the hemispherical end of the limiting member 4143 is inserted into the limiting groove 19. Under the action of the limiting member 4143 and the limiting groove 19, the spliced ​​connector 41 and the plug 11 are limited, which further improves the stability of the two after splicing.

[0035] In addition, a first bevel 110 is formed at the front edge of the top surface and the front edge of the bottom surface of the plug 11 to guide the hemispherical end of the limiting member 4143. With the cooperation of the first bevel 110 and the hemispherical end, during the process of aligning the insert 412 with the groove 18 and applying force to the splice 41, the sliding member 4142 automatically slides in the sliding chamber 4141 and compresses the spring 4144, making splicing more convenient.

[0036] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0037] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
