Description

Technical Field

[0001] This utility model relates to the field of electrical connection mechanism technology, and more specifically to a connector for energy storage systems and electric motorcycles. Background Technology

[0002] Currently, with the development of energy storage systems and electric motorcycle technology, higher demands are being placed on the performance of electrical connectors, especially in areas such as high-current transmission, safety protection, signal communication, and waterproof sealing. Traditional connectors often employ a single conductive structure, lacking effective separation and protection for power, signal, and grounding. This can easily lead to problems such as unstable mating, poor contact, signal interference, and water ingress short circuits, failing to meet the requirements for high-frequency mating and long-term stable use in harsh environments. Furthermore, existing connectors are weak in their design for protection against electric shock, incorrect mating, and vibration-induced loosening, posing significant safety hazards. Therefore, there is an urgent need for a connector with a more rational structure and more comprehensive functions, capable of providing high-current power supply, low-voltage signal transmission, and grounding functions, while possessing excellent sealing, safety, and positioning mating performance to improve the overall system stability and user operational reliability. Utility Model Content

[0003] In view of this, the present invention provides a connector for energy storage systems and electric motorcycles.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A connector for energy storage systems and electric motorcycles includes a plug and a socket. The plug includes a plug housing, two large male hardware components, two positioning posts, a small male hardware component, and multiple plug signal pins. The large male hardware components have a waterproof ring and are fixed inside the plug housing. An insulating cap is fitted at the front end to prevent accidental contact. The positioning posts are located at the front end of the plug housing for precise positioning during insertion. The socket includes a socket housing, two large female hardware components, multiple socket signal pins, and a small female hardware component. The large female hardware components have a waterproof ring. The plug housing has a protrusion for insertion into the socket housing. The socket housing has a slot that mates with the protrusion and a slot corresponding to the positioning posts. The plug is inserted into the slot through the protrusion and achieves precise positioning and connection through the engagement of the positioning posts and the slots, completing a reliable connection for power, signal, and grounding.

[0005] In a preferred embodiment, the plug further includes a waterproof ring, which is fitted over the outside of the protrusion. The protrusion has a recessed fixing groove, and the waterproof ring is embedded in the fixing groove for installation. After the plug is inserted into the slot, the outer protrusion of the waterproof ring forms an interference fit with the inner wall of the slot, thereby achieving a waterproof seal between the plug and the socket.

[0006] In the preferred embodiment, the plug further includes a plug cover for encapsulating the internal structure of the plug and clamping the cable; the socket further includes a socket cover for sealing and fixing the internal components of the socket. Both the plug cover and the socket cover are provided with cable outlet holes and are fixedly connected to the housing.

[0007] In a preferred embodiment, the rear sides of the plug housing and the socket housing are respectively provided with a plug gasket and a socket gasket to assist in the connection of the fixing structure.

[0008] In the preferred technical solution, each male hardware in the plug and socket is connected to the corresponding female hardware for transmitting a large current, with a rated current of 60A.

[0009] In the preferred technical solution, there are 8 plug signal pins and 8 socket signal pins, which are evenly distributed inside the plug and socket and used to realize data or control signal transmission.

[0010] In the preferred technical solution, the male connector in the plug and the female connector in the socket are connected for grounding protection.

[0011] In the preferred embodiment, the insulating cap is made of elastic insulating material and is fitted onto the front end of the connector, covering the portion exposed near the front end of the protrusion. This is to prevent accidental contact by foreign objects or fingers and to improve the electrical safety of the connector.

[0012] In the preferred embodiment, the plug housing and socket housing are made of flame-retardant plastic or high-strength insulating material to enhance structural strength and high-temperature resistance.

[0013] In the preferred technical solution, the plug signal pin and the socket signal pin are equipped with a foolproof structure to ensure that the plug and socket can only be connected in one direction, preventing mis-insertion and reverse insertion.

[0014] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects: By incorporating large male and female connectors, small male and female connectors, and multiple signal pins, physical separation of power, signal, and grounding is achieved, effectively preventing short-circuit interference and ensuring the reliability of power and communication channels. The main power channel uses large-diameter copper alloy conductors, supporting 60A current output to meet the power supply requirements of energy storage systems for high-power loads. An interference fit is formed between the plug's waterproof ring and the socket slot. Independent waterproof rings are provided on both the female and male ends, creating a double-sealed structure that achieves IP-level protection, preventing rainwater and dust intrusion and improving environmental adaptability. A flexible insulating cap is provided at the front end of the conductor to prevent accidental electric shock; all contacts are embedded within the housing to avoid exposure and ensure safe use. Positioning posts on the plug guide the insertion direction, preventing reverse or misaligned insertion and improving accuracy and ease of operation. The plug-and-play connection requires no tools, meeting high-frequency usage requirements and facilitating quick on-site disassembly and replacement. Attached Figure Description

[0024] A connector for energy storage systems and electric motorcycles, please refer to [link / reference]. Figure 1-4The structure comprises two parts: a plug 1 and a socket 2. Its main functions are to provide high-current power supply, signal communication, grounding, and protective connections, ensuring safety, stability, and waterproof reliability. The plug 1 includes: a plug housing 11: the main structure of the plug 1, made of insulating material, used to house and fix all internal components. It has a protrusion 111 at the front end for insertion into the socket 2 to complete the connection. The protrusion 111 is the protruding connecting part at the front end of the plug housing 11, its shape matching the slot 211 in the socket for guiding insertion. The protrusion may have a through hole for the male hardware to protrude or for use with an insulating cap. Two male hardware 15: the main positive and negative conductive components for the power supply, generally made of copper alloy, fixed inside the plug housing 11, corresponding to the two female hardware 22 in the socket; the male hardware 15 has a waterproof ring 19 on its exterior to enhance sealing performance. An insulating cap 110 is provided at the front end of the male hardware to cover its exposed end, preventing accidental contact and improving safety. Insulating cap 110: Made of elastic insulating material, it is fitted onto the front end of the large male hardware 15, covering its exposed area to prevent foreign objects or fingers from contacting the conductor and improving the protection level. The insulating cap 110 adopts a flexible snap-fit ​​structure, fitted onto the front end of the large male hardware 15, and tightly fitted with the plug housing 11 to prevent it from falling off. A small male hardware 17: Used for grounding connection, located inside the plug, corresponding to the small female hardware 24 in the socket, forming a reliable grounding path. Multiple plug signal pins 18: A total of 8 signal pins, used for low-voltage communication signal transmission, corresponding one-to-one with the socket signal pins 23 in the socket to ensure system data interaction. Two positioning posts 16: Symmetrically arranged on both sides of the protrusion 111 of the plug housing 11, used to mate with the slots 212 in the socket to achieve accurate positioning between the plug and the socket, preventing incorrect or crooked insertion. Plug waterproof ring 14: Fitted onto the outside of the protrusion 111 and embedded in the fixing groove 112 provided on the protrusion. The outer diameter of the plug waterproof ring 14 is slightly larger than the inner diameter of the socket housing slot 211, forming an interference fit during insertion to generate appropriate clamping force and ensure a sealing effect. The large male hardware 15, small male hardware 17, and plug signal pin 18 are all fixed inside the plug housing 11 by injection molding or a snap-fit ​​structure. Their corresponding ends are connected to the cable via crimp terminals or soldering to ensure reliable conductivity and shock resistance. The plug waterproof ring 14 is made of flexible elastic material and is embedded in the fixing groove 112 on the outside of the protrusion 111, allowing it to adhere firmly to its surface after installation. When inserted into the socket, the waterproof ring forms a tight seal against the inner wall of the slot 211, providing a high level of sealing.

[0025] Furthermore, the socket 2 includes: a socket housing 21 made of insulating material, which houses the various socket components. A slot 211 at the front mates with the plug protrusion 111 for receiving the plug portion. The slot 211 is a recessed structure for inserting the plug protrusion 111, and its inner wall mates with the plug waterproof ring 14 to form a sealing structure. Two large female hardware units 22 are high-current input terminals, corresponding to the large male hardware units 15 of the plug to complete the main circuit connection. They are externally equipped with female hardware waterproof rings 27 to enhance sealing performance. The female hardware waterproof ring 27 is an annular sealing ring fitted over the large female hardware units to improve sealing performance after plug insertion and prevent moisture from entering the contact area. A small female hardware unit 24 connects to the small male hardware unit 17 of the plug to achieve grounding closure and ensure safe system grounding. Multiple socket signal pins 23 contact the signal pins 18 of the plug one by one for transmitting and receiving low-voltage signals, realizing control and status feedback functions. Slot 212: Located at the front end of the socket housing 21, it mates with the positioning pins 16 on the plug to ensure accurate insertion direction and position, preventing reverse or off-center insertion. The large female hardware 22, small female hardware 24, and socket signal pin 23 of the socket are also fixed inside the socket housing 21 by injection molding, with the tail end connected to the socket-side cable and having a limiting and positioning structure to prevent loosening. The above description of the disclosed embodiments enables those skilled in the art to implement or use this utility model.

[0026] Furthermore, the connection process between plug 1 and socket 2 is as follows: plug 1 is inserted into socket 2 by aligning its protrusion 111 with the slot 211; positioning pin 16 is aligned with slot 212 on socket housing to ensure stable connection; during insertion, plug waterproof ring 14 is press-fitted with the inner wall of slot to form a waterproof seal; the large male hardware 15, small male hardware 17 and signal pin 18 in plug contact the corresponding female terminal in socket; insulating cap 110 covers the conductive front end to further prevent exposure; after insertion, reliable connection of power supply (60A high current), signal (8-pin communication) and grounding is achieved; plug can be pulled out reversibly during disassembly. The plug and socket are equipped with independent power supply channels, signal channels and grounding channels. Large male hardware 15 and large female hardware 22 form the main power supply channel, small male hardware 17 and small female hardware 24 constitute an independent grounding path, and plug signal pin 18 and socket signal pin 23 constitute multiple low-voltage communication channels. All contacts are separated by an insulating housing structure to prevent short circuits or interference between different channels, ensuring stable transmission of both high-current and low-voltage signals simultaneously. The signal pin channels are compatible with communication protocols such as CAN and RS485, enabling real-time information exchange between the energy storage system and the electric motorcycle's main control unit.

[0027] Furthermore, this connector achieves a high current transmission of 60A through the contact between two large male hardware pins 15 and large female hardware pin 22, suitable for applications such as energy storage systems supplying power to electric motorcycles. Eight signal pins form an independent channel, isolated from the main current channel, for data interaction using communication protocols such as CAN and RS485, ensuring real-time and reliable system control and status feedback. A grounding path is formed by connecting the small male hardware pin 17 and small female hardware pin 24, eliminating the risk of static electricity or overvoltage and enhancing electrical safety. The plug's waterproof ring 14 fits tightly with the slot, and the female hardware's waterproof ring 27 provides double protection. Combined with the insulating cap 110's anti-touch design, it achieves IP-level protection. The positioning post 16 mates with the slot 212 to ensure correct insertion direction and consistent position each time, improving the user's insertion experience and reducing the failure rate. Safety protection design: Multiple insulation encapsulations and accidental contact protection design ensure user safety and avoid risks such as short circuits, electric shocks, or incorrect insertion. When using the device, align the plug 1 with the socket 2. The positioning pin 16 engages with the slot 212 to ensure accurate orientation. During insertion, the waterproof ring 14 is gradually pressed into the slot 211 until fully fitted. A clear, fully inserted feel indicates successful connection. Disassembly is simple: just pull out the plug housing 11. The entire insertion and removal process requires no rotation or tools, meeting the needs of frequent insertion and removal, and facilitating on-site maintenance and replacement.

[0028] Furthermore, the plug housing 11 and socket housing 21 are preferably made of high-strength, high-temperature resistant, and flame-retardant insulating materials such as modified nylon to ensure long-term stability in high-temperature and humid environments. The high-current contacts, such as the male hardware 15 and female hardware 22, are preferably made of silver-plated copper alloy, possessing excellent conductivity and corrosion resistance. The plug waterproof ring 14 and female hardware waterproof ring 27 are preferably made of high-elastic silicone or TPV material, possessing good heat resistance, cold resistance, and aging resistance. The insulating cap 110 is preferably made of TPU soft insulating material, possessing good coverage and flexibility.

[0029] Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
