[0002] In outdoor centralized charging scenarios for electric motorcycles, charging connectors need to balance high-power transmission, signal stability, and environmental adaptability. Existing plugs often suffer from unreasonable arrangement of power and signal pins, which can easily generate electromagnetic interference, affecting charging efficiency and signal transmission accuracy. At the same time, the high charging frequency of electric motorcycles places stringent requirements on the reliability of pin positioning and the durability of insertion and removal; traditional layouts struggle to achieve effective isolation and precise positioning within limited space.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0017] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0018] like Figures 1 to 4 As shown, this embodiment provides a plug for an electric motorcycle charging connector, including: a main body 00, an inner frame 200, and a terminal assembly.

[0019] Main body 00; Main body 00 is a component formed by injection molding.

[0020] The inner frame 200 has a mating surface and an inner contact surface that are spaced apart. The mating surface of the inner frame 200 is provided with a first slot 210 and a second slot 220. There are two first slots 210 that are spaced apart. The second slot 220 is located on one side of the two first slots 210. The inner contact surface of the inner frame 200 is located in the main body 00. The inner contact surface of the inner frame 200 is provided with a first countersunk hole 230 that communicates with the first slot 210. The first countersunk hole 230 corresponds one-to-one with the first slot 210. The inner contact surface of the inner frame 200 is provided with a second countersunk hole 240 that communicates with the second slot 220. There are six second countersunk holes 240. The inner frame 200 is a component that houses and supports the terminal assembly. The inner frame 200 is connected and fixed to the main body 00 during injection molding. It can be understood that the inner surface of the inner frame 200 faces the main body 00, i.e., the cable connection side. The mating surface of the inner frame 200 faces the socket.

[0021] It is understandable that the first countersunk hole 230 and the second countersunk hole 240 in the inner frame 200 are used to fix the terminals and prevent them from shifting during insertion and removal.

[0022] The terminal assembly includes power terminals and signal terminals. There are two power terminals, one of which passes through the first countersunk hole 230 and a portion of which is located in the first slot 210. There are six signal terminals, one of which passes through the second countersunk hole 240 and a portion of which is located in the second slot 220.

[0023] Two power terminals pass through the corresponding first countersunk holes 230 from one side of the inner surface of the inner frame 200. The portions of the power terminals that contact the socket extend into the first slot 210. The two power terminals are a positive power terminal and a negative power terminal, respectively.

[0024] Six signal terminals pass through six second countersunk holes 240 from one side of the inner surface of the inner frame 200, and the part of the signal terminal that contacts the socket extends into the second slot 220.

[0025] The plug provided in this embodiment places two power terminals in two spaced-apart first slots 210, and six signal terminals in a single-sided second slot 220. This layout effectively separates and isolates high-voltage and low-voltage circuits at the mating surface, improving the electrical safety of the charging connection and preventing signal interference. Furthermore, the inner frame 200, as a core component, integrates the main body 00, power terminals, and signal terminals through a countersunk hole and slot connection design, resulting in a compact and stable structure that ensures the positional accuracy and connection reliability of the terminals during insertion and removal.

[0026] like Figures 1 to 4 As shown, in some embodiments, the width of the inner frame 200 is 17.98 mm to 18.58 mm.

[0027] Specifically, the width of the inner frame 200 is 18.28mm.

[0028] like Figures 1 to 4 As shown, in some embodiments, the first slot 210 is a square slot.

[0029] like Figures 1 to 4 As shown, in some embodiments, the second slot 220 is an oblong slot.

[0030] Understandably, the oblong slot can accommodate multiple signal terminals within a limited width, achieving a compact signal terminal arrangement and saving space on the mating surface. Furthermore, the combination of the oblong slot and the first slot 210 provides very clear insertion guidance and direction. This asymmetrical slot layout strongly prevents incorrect plug insertion, further improving operational safety.

[0031] like Figures 1 to 4 As shown, in some embodiments, a first extension 250 and a second extension 260 are provided on the inner surface. The first extension 250 is provided with a first extension hole 251 communicating with a first countersunk hole 230, and a portion of a power terminal is located in the first extension hole 251. The second extension 260 is provided with a second extension hole 261 communicating with another first countersunk hole 230, and a portion of another power terminal is located in the second extension hole 261.

[0032] Understandably, during installation, the two power terminals not only pass through the first countersunk hole 230, but their tails, i.e., the parts connecting the cables, also pass through the extension holes on these two extensions. This adds extra support to the tails of the power terminals, greatly enhancing their mechanical stability.

[0033] like Figures 1 to 4 As shown, in some embodiments, the length of the first extension 250 is greater than the length of the second extension 260.

[0034] Understandably, by setting the first extension 250 and the second extension 260 to have different lengths, error-proof installation during the assembly process is achieved. For example, if one power terminal is designed as positive and the other as negative, the different extension lengths can ensure that a specific terminal can only be installed in a specific hole, thereby preventing reversed positive and negative installation or wiring errors, which is crucial for safe production and safe use.

[0035] like Figures 1 to 4 As shown, in some embodiments, an annular groove is provided on the outer peripheral surface of the inner frame 200, and a sealing ring 270 is provided in the annular groove.

[0036] Understandably, when the plug and socket are connected, the sealing ring 270 is compressed, forming a sealing barrier. In this way, after the plug and socket are engaged, external contaminants such as moisture and dust can be effectively prevented from entering the plug's interface and interior.

[0037] Figure 5 This is a structural breakdown diagram of the main body and the assisting mechanisms. Figure 6 This is a structural diagram of the main body and the supporting mechanisms.

[0038] like Figure 5 and Figure 6As shown, in some embodiments, the plug includes an assist mechanism 400, which includes a first mating member 410 and an assist rod 420. The first mating member 410 has two parts and is located at opposite ends of the main body. The axis of the first mating member 410 is a rotation axis. The assist rod 420 is provided with a mating hole 421 that mates with the first mating member 410. The assist rod 420 is configured to rotate relative to the main body about the rotation axis, thereby assisting the plug in and out of the socket.

[0039] The first mating component 410 is a member rotatably connected to the assist rod 420. It is understood that the first mating component 410 may include a column portion 411 and an abutment portion 412. The column portion 411 is connected to the main body, and the abutment portion 412 is connected to the outer peripheral surface of the column portion 411. In the assist rod 420, a circular retaining ring is provided on the inner peripheral surface of the mating hole 421. The circular retaining ring has a notch, the size of which is approximately the same as the size of the abutment portion 412. During assembly, the notch of the circular retaining ring is aligned with the abutment portion 412. Then, the mating rod of the assist rod 420 is fitted onto the first mating component 410. Thus, the column portion 411 passes through the circular retaining ring, and the abutment portion 412 passes through the notch. Rotating the assist rod 420 causes the notch and the abutment portion 412 to shift, at which point the abutment portion 412 abuts against the circular retaining ring, thereby preventing the assist rod 420 from detaching from the main body.

[0040] In some embodiments, the abutment portion 412 is connected to the end of the post portion 411, such that there is a gap between the abutment portion 412 and the body, thereby enabling it to engage with the circular retaining ring.

[0041] The assist rod 420 is a component capable of rotating around a rotation axis to assist in the insertion and removal of the plug and socket. It is understood that the assist rod 420 has an arc-shaped groove 422, the opening of which is located on the side of the assist rod 420. The bottom surface of the assist rod 420 is arc-shaped and connected to its side surface. A second mating member, cylindrical in shape, is provided in the socket. During insertion and removal, the assist rod 420 is rotated so that the opening of the arc-shaped groove 422 aligns with the second mating member. The plug is moved closer to the socket, causing the second mating member to enter the arc-shaped groove 422. Pressing the pressing end of the assist rod 420 causes it to rotate, and the second mating member slides into the arc-shaped groove 422, allowing the socket to be finally inserted into the socket, completing the insertion connection. Thus, by manually pressing the assist rod 420, and with the sliding engagement of the second mating part and the arc groove 422, it is convenient to plug and unplug the plug and socket.
