[0002] With the development of the new energy industry, electric vehicles are becoming increasingly widespread in the market, and charging devices are an inevitable part of electric vehicle production. Electric vehicles are generally equipped with charging sockets for connecting to a charging gun to charge the vehicle's battery. To prevent the charging terminals in the charging socket from being pushed out by the charging gun, a locking mechanism is needed to secure the charging terminals within the charging socket.

[0003] In existing technologies, besides using a primary locking arm formed inside the socket housing to lock onto the charging terminals, secondary locking of the charging terminals is usually achieved through the structural design of the conductive frame in the socket housing or additional secondary locking components. However, whether using a structural design of the conductive frame or additional secondary locking components, not only does it increase design / component costs, but it also increases the overall size of the socket.

[0004] Therefore, it is necessary to provide a new charging socket to solve the above problems. Utility Model Content

[0033] Figure 1 This diagram shows a perspective view of a charging socket according to an exemplary embodiment of the present invention. Figures 2 to 4 They are from Figure 1 Schematic diagram of cross-sectional structure taken from different angles.

[0034] According to this utility model, see Figures 1 to 4 A charging socket 10 is provided. The charging socket 10 mainly consists of a housing 110 and a socket assembly disposed within the housing 110. The housing 110 is designed to be robust and waterproof to protect its internal electrical components from damage by the external environment. The socket assembly is the core part of the charging socket 10, and it mainly includes charging terminals 120A and 120B for power transmission, as well as other necessary components required for the charging socket 10 to achieve its purpose (e.g., including but not limited to signal terminals for signal transmission, printed circuit boards for charging control and signal processing, sealing gaskets for waterproof sealing, etc.).

[0035] The following content of this utility model mainly relates to the secondary locking of the positive and negative DC charging terminals 120A and 120B inside the charging socket 10.

[0036] See Figures 1 to 4 According to an exemplary embodiment of the present invention, a charging socket 10 suitable for electric vehicles is provided. The charging socket 10 includes a housing 110 and a positive DC charging terminal 120A and a negative DC charging terminal 120B disposed within the housing 110. Figure 1 As shown, the housing 110 has a plug-in port 111, and a first terminal receiving cavity 101A and a second terminal receiving cavity 101B are formed inside the plug-in port 11; wherein, the positive DC charging terminal 120A is received in the first terminal receiving cavity 101A, and the negative DC charging terminal 120B is received in the second terminal receiving cavity 101B. According to the design concept of this utility model, a set of structures for achieving primary and secondary locking of each charging terminal, including the positive DC charging terminal 120A and the negative DC charging terminal 120B, is specifically designed. Therefore, the following description will not distinguish between the positive DC charging terminal 120A and the negative DC charging terminal 120B. Specifically, as... Figures 1 to 4As shown, the charging socket 10 also includes a first locking structure 130, a fastener 140, and a stop structure 150. The first locking structure 130 is located within the terminal receiving cavities 101A and 101B and is used to achieve a primary locking of the charging terminals 120A and 120B. The fastener 140 is used to fasten the ribbon cable 20 to the charging terminals 120A and 120B. The stop structure 150 is formed on the inner wall of the housing 110. The fastener 140 is configured such that while fastening the ribbon cable 20 to the charging terminals 120A and 120B, the tail 141 of the fastener 140 abuts against the stop structure 150 to achieve a secondary locking of the charging terminals 120A and 120B. It should be noted that the ribbon cable 20 described herein may be, for example, an aluminum power / signal transmission cable assembly, and the fastener 140 described herein may be, for example, a fastener (e.g., a fastening screw) used to secure the connection between the ribbon cable 20 and the charging terminals 120A, 120B.

[0037] See Figures 1 to 4 According to an exemplary embodiment of the present invention, specifically, charging terminals 120A and 120B are disposed within the insertion port 111 of the housing 110. The charging terminals 120A and 120B have an insertion end 121 and a fastening end 122 opposite to the insertion end 121. The insertion port 111 of the housing 110 and the insertion ends 121 of the charging terminals 120A and 120B have the same opening orientation. Simultaneously, the housing 110 also forms a fastener receiving opening 112, and the fastening ends 122 of the charging terminals 120A and 120B have fastening holes 123. The fastener 140 enters the interior of the housing 110 through the fastener receiving opening 112 and sequentially passes through the fastening opening of the aluminum busbar 20 and the fastening holes 123 at the fastening ends 122 of the charging terminals 120A and 120B, thereby fastening the aluminum busbar 20 to the fastening ends 122 of the charging terminals 120A and 120B.

[0038] See Figures 1 to 4 According to an exemplary embodiment of the present invention, a first locking structure 130 is designed to achieve a primary locking of charging terminals 120A and 120B. Specifically, the first locking structure 130 includes a pair of locking cantilever arms 131 extending from the inner walls of the terminal receiving cavities 101A and 101B. These locking cantilever arms 131 engage with grooves 124 formed on the outer walls of the insertion ends 121 of the charging terminals 120A and 120B. The pair of locking cantilever arms 131 engage with the grooves 124 from radially opposite ends of the insertion ends 121 of the charging terminals 120A and 120B. When the charging terminals 120A and 120B are inserted into the terminal receiving cavities 101A and 101B, the locking cantilever arms 131 engage with the grooves 124 formed on the outer walls of the insertion ends 121 of the charging terminals 120A and 120B, thereby achieving a primary locking of the charging terminals 120A and 120B.

[0039] According to the design concept of this utility model, a stop structure 150 is provided on the inner wall of the housing 110. Thus, while the fastener 140 secures the ribbon cable 20 to the charging terminals 120A and 120B, the tail 141 of the fastener 140 abuts against the stop structure 150, thereby achieving a secondary locking of the charging terminals 120A and 120B. Specifically, see... Figures 1 to 3 According to an exemplary embodiment of the present invention, the fastener 140 passes through the fastening hole 123 and its tail 141 abuts against the stop structure 150. More specifically, in a direction perpendicular to the insertion direction of the charging terminals 120A and 120B, the stop structure 150 and the fastener receiving opening 112 are respectively formed on opposite sides of the housing 110. In a direction parallel to the insertion direction of the charging terminals 120A and 120B, the side of the tail 141 of the fastener 140 away from the insertion end 121 of the charging terminals 120A and 120B abuts against the stop structure 150. In the illustrated embodiment, the stop structure 150 may be a protruding rib extending from the inner wall of the housing 110.

[0040] The charging socket provided according to the foregoing exemplary embodiments of the present invention achieves secondary locking of the charging terminals by using a screw for assembling the charging terminals to abut against a blocking structure formed inside the socket housing. This avoids structural design of the conductive frame or the use of additional secondary locking parts, which not only reduces manufacturing costs but also reduces the overall size of the socket.
