Description
Technical Field
[0001] This utility model belongs to the field of energy storage connection technology, and specifically relates to a battery connector and electrical equipment with flexible connection orientation. Background Technology
[0002] With the rapid development of electric bicycles, energy storage devices, and other fields, batteries, as core energy components, especially sodium-ion batteries with high safety and long service life, have significantly extended the lifespan of electrical equipment, particularly shared electric vehicles. Consequently, the charging convenience and safety of corresponding components have become a major concern. In existing technologies, batteries and charging devices are typically connected via connectors. Connectors generally include compatible male and female terminals. The male terminal has positive power pins, negative power pins, and signal pins, while the female terminal has corresponding pin holes. Power transmission and signal interaction are achieved through the interaction of the pins and pin holes.
[0003] However, existing connectors often have the limitation of a fixed connection orientation, meaning that the male and female terminals can usually only be effectively connected at a specific angle (such as forward or reverse). In practical applications, factors such as battery installation position deviations, limited operating space, or external vibrations (such as the bumps of an electric bicycle) often make it difficult to quickly align the male and female terminals, or cause stress on the wiring after connection due to incorrect orientation. This not only increases the difficulty of operation but may also affect the stability and lifespan of the connection due to the stress on the wiring.
[0004] Especially in high-current transmission scenarios, uneven contact pressure between the electrode and the hole can lead to increased resistance and even cause safety hazards such as overheating. In applications such as automated charging equipment or multi-directional charging interfaces, a fixed connection orientation cannot meet the needs of multi-angle docking, which limits the adaptability and flexibility of the equipment.
[0005] Therefore, a flexible battery connector and electrical device are needed. Utility Model Content
[0006] The purpose of this invention is to provide a battery connector and electrical equipment with flexible connection orientation, increasing the flexibility of the wiring connection orientation by providing multiple orientations for easy connection operation. It also prevents the wiring from being subjected to additional tensile force due to incorrect orientation, thereby improving the stability and reliability of the electrical connection. The specific technical solution is as follows: A flexible battery connector includes: a female connector and a male connector; the female connector has a first terminal hole, a plurality of second terminal holes, and a plurality of pin hole groups; the plurality of second terminal holes are evenly distributed around the first terminal hole; the plurality of pin hole groups are evenly distributed around the first terminal hole; the number of pin hole groups corresponds to the number of second terminal holes; the male connector has a first terminal, a second terminal, and a pin assembly; the first terminal is inserted into the first terminal hole; the second terminal is inserted into one of the second terminal holes; the pin assembly is inserted into one of the pin hole groups.
[0007] Furthermore, the female connector is provided with a plurality of guide post holes; the guide post holes are evenly distributed around the first pole post hole; the number of guide post holes corresponds to the number of second pole post holes; the male connector is also provided with a first guide post; the first guide post is inserted into and connected to one of the guide post holes.
[0008] Furthermore, the male head is also provided with a second guide post; the second guide post is inserted and connected to another guide post hole among a plurality of guide post holes.
[0009] Furthermore, the number of guide post holes is even; the first guide post and the second guide post are symmetrically arranged with the first pole post hole as the center.
[0010] Furthermore, each group of the pin holes includes a first pin hole, a second pin hole, and a third pin hole; the pin assembly includes a first pin, a second pin, and a third pin that are respectively connected to the first pin hole, the second pin hole, and the third pin hole.
[0011] Furthermore, the first pin hole, the second pin hole, and the third pin hole are arranged in an arc shape with the first pole hole as the center.
[0012] Furthermore, the male connector includes a first housing, a connector, and a first cover plate; the first cover plate is installed on the top of the first housing to form a first mounting cavity; the first electrode post, the second electrode post hole, and the pin assembly are located on the connector; the connector is located in the first mounting cavity and is movably installed on the first housing; a first movable cavity is provided between the connector and the inner wall of the first housing; a plurality of first elastic members are installed on the top of the connector; a plurality of elastic member sleeves are provided on the bottom surface of the first cover plate; the first elastic members are installed in the elastic member sleeves.
[0013] Furthermore, the connector includes a plug plate and a second cover plate; the second cover plate is fixedly connected to the plug plate, the first pole post, the second pole post hole and the pin assembly respectively, so as to fix the first pole post, the second pole post hole and the pin assembly to the plug plate.
[0014] Furthermore, the female connector includes a second housing and a third cover plate; the first pole post hole, a plurality of second pole post holes, and a plurality of pin hole groups are located on the second housing; the first pole post hole and the second pole post hole are respectively provided with a first metal elastic element; each pin hole of the pin hole group is provided with a second metal elastic element; the third cover plate is fixedly connected to the bottom of the second housing, the first metal elastic element, and the second metal elastic element, respectively, so as to fix the first metal elastic element and the second metal elastic element in the second housing.
[0015] An electrical device includes a battery connector with the above-described flexible orientation.
[0016] Compared with existing technologies, this utility model has the following beneficial effects: 1. In existing technologies, connectors typically only allow mating at specific angles, such as forward or reverse, failing to meet multi-angle connection requirements. This solution uses the first pole as the turning center, evenly distributing several second pole holes, pin holes, and guide holes around the first pole hole. This allows the male connector to achieve precise mating with the female connector at multiple angles (such as 30°, 60°, 90°, etc.), overcoming the limitation of only being able to plug in two directions. It is particularly suitable for scenarios such as automated charging equipment and multi-directional charging interfaces.
[0017] 2. In existing technologies, when a battery undergoes slight displacement due to vibration or external forces, it is prone to poor contact between the male and female terminals, affecting connection stability and service life, which is particularly evident in scenarios such as the bumpy ride of an electric bicycle. In this solution, the guide post and the first electrode post are symmetrically positioned, and the first electrode post uses a larger radius as the central post, which can reduce the offset amplitude of vibration; at the same time, the power pins (first electrode post and second electrode post) are distributed close to the turning center, resulting in a smaller radius of arc of the movement trajectory during insertion and removal, and more uniform contact pressure with the corresponding holes, which can reduce wear between the electrode post and the hole wall, and significantly improve the stability of high current transmission and structural durability.
[0018] 3. In existing technologies, under high-current transmission scenarios, uneven contact pressure between the electrode and the hole can lead to increased resistance and even cause safety hazards such as overheating. In this solution, the first and second electrodes, as core conductive components, are designed close to the turning center to reduce alignment errors caused by angular deviations, ensure uniform contact pressure, further guarantee the reliability of power transmission, and reduce safety hazards.
[0019] 4. In existing technologies, a fixed connection orientation often makes it difficult to quickly align the male and female terminals, increasing the workload for users, especially for heavy battery components. In this solution, guide pin holes are evenly distributed around the first electrode hole, and their number corresponds to the second electrode hole. The guide pins of the male connector can cooperate with different guide pin holes depending on the insertion angle, forming a guiding mechanism adapted to the positioning of the power pins. Even at non-positive / reverse angles, the position can be quickly corrected by the cooperation of the guide pins and corresponding guide pin holes, reducing repeated adjustments by the user and improving the user experience.
[0020] 5. When the battery undergoes slight displacement due to vibration, external force, etc., the guide post and the first pole post form a symmetrical orientation. At the same time, by using the larger radius of the first pole post as the central post, the displacement amplitude of the vibration can be reduced, thereby improving the stability and lifespan of the connection in scenarios such as the bumpy ride of an electric bicycle.
[0021] 6. The solution in this application uses the first terminal as the turning center, and the distribution of the power pins (first terminal and second terminal) is closer to the turning center. This results in a smaller radius of curvature for the movement trajectory during insertion and removal, and more uniform contact pressure with the corresponding holes. This reduces wear between the terminal and the hole wall, improving the stability of high-current transmission and structural durability. Simultaneously, the design of the first and second terminals, as core conductive components, being close to the turning center reduces alignment errors caused by angular deviations, further ensuring the reliability of power transmission.
[0022] 7. In this application, the guide pin holes are evenly distributed around the first electrode pin hole, and their number corresponds to the second electrode pin hole. The male connector's guide pins can cooperate with different guide pin holes depending on the insertion angle, forming a guiding mechanism adapted to the positioning of the power connector pins. This design allows the guiding function to work in tandem with the turning center of the power connector pins. Even at non-positive / reverse angles, the position can be quickly corrected through the cooperation of the guide pins and corresponding guide pin holes, reducing the need for repeated adjustments by the user. This is especially beneficial for heavier battery components, significantly reducing operational intensity and improving the user experience. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.
[0031] Example 1 like Figures 1 to 8 The diagram shows a structural schematic of a flexible battery connector, including: a female connector 2 and a male connector 1; the female connector 2 has a first terminal hole 211, a plurality of second terminal holes 213, and a plurality of pin hole groups 214; the plurality of second terminal holes 213 are evenly distributed around the first terminal hole 211; the plurality of pin hole groups 214 are evenly distributed around the first terminal hole 211; the number of pin hole groups 214 corresponds to the number of second terminal holes 213; the male connector 1 has a first terminal 121, a second terminal 122, and a pin assembly 124; the first terminal 121 is inserted into the first terminal hole 211; the second terminal 122 is inserted into one of the plurality of second terminal holes 213; the pin assembly 124 is inserted into one of the plurality of pin hole groups 214.
[0032] In existing technologies, connectors can typically only be mated at specific angles, such as forward or reverse, failing to meet the needs of multi-angle connections. This solution uses the first pole post 121 as the turning center, and evenly distributes several second pole post holes 213, pin hole groups 214, and guide post holes 212 around the first pole post hole 211, enabling the male connector 1 to achieve precise mating with the female connector 2 at multiple angles (such as 30°, 60°, 90°, etc.), breaking through the limitation of only being able to be plugged in two directions. It is especially suitable for scenarios such as automated charging equipment and multi-directional charging interfaces.
[0033] Meanwhile, compared to the steering method centered on the signal pin, although a guide post can be added, when the battery undergoes slight displacement due to vibration, external force, etc., although the guide post can limit some radial displacement, if the first pole post 121 is not used as the steering center and is far away from the steering center, the first pole post 121 and the second pole post 122 will be more sensitive to displacement (because the signal pin has a small radius and weak displacement limiting force), and poor contact may still occur, which is especially obvious in scenarios such as the bumps of electric bicycles. Therefore, this application uses the first pole post 121 as the steering center, which can improve the stability and reliability of the connection.
[0034] In a specific implementation, the female connector 2 is also provided with a plurality of guide post holes 212; the guide post holes 212 are evenly distributed around the first pole post hole 211; the number of guide post holes 212 corresponds to the number of second pole post holes 213; the male connector 1 is also provided with a first guide post 123; the first guide post 123 is inserted and connected to one of the guide post holes 212.
[0035] Furthermore, the male head 1 is also provided with a second guide post 125; the second guide post 125 is inserted and connected to another guide post hole 212 among a plurality of guide post holes 212.
[0036] Furthermore, the number of guide post holes 212 is even; the first guide post 123 and the second guide post 125 are symmetrically arranged with the first pole post hole 211 as the center.

[0038] Furthermore, the first pin hole 2141, the second pin hole 2142, and the third pin hole 2143 are arranged in an arc shape with the first pole hole 211 as the center. Furthermore, the distance from the pin assembly 124 to the first pole 121 is less than the distance from the second pole 122 to the first pole 121.
[0039] In a specific implementation, the male connector 1 includes a first housing 13, a connector 12, and a first cover plate 11; the first cover plate 11 is installed on the top of the first housing 13 to form a first mounting cavity; the first electrode post 121, the second electrode post hole 213, the pin assembly 124, the first guide post 123, and the second guide post 125 are located on the connector 12; the connector 12 is located in the first mounting cavity and is movably installed on the first housing 13; the bottom of the first housing 13 has an opening, allowing the first electrode post 121, the second electrode post hole 213, the second electrode post hole 213, the first guide post 124, the second guide post 125 to pass through the first mounting cavity. The insertion pin hole 213, pin assembly 124, first guide post 123, and second guide post 125, etc., can extend beyond the first housing 13 when inserted into the female connector 2. A first movable cavity 131 is provided between the connector 12 and the inner wall of the first housing 13, so that the connector 12 has elastic movement space when the male connector 1 is vibrated. Several first elastic elements 127 are installed on the top of the connector 12. Several elastic element sleeves 111 are provided on the bottom surface of the first cover plate 11. The first elastic elements 127 are installed in the elastic element sleeves 111. This allows the first housing 13 to reduce the transmission of vibration force to the connector 12 when subjected to external vibration, thus maintaining the connection reliability between the male connector 1 and the female connector 2.
[0040] Furthermore, the connector 12 includes a plug plate 128 and a second cover plate 126; the second cover plate 126 is fixedly connected to the plug plate 128, the first pole post 121, the second pole post hole 213 and the pin assembly 124 respectively, so as to fix the first pole post 121, the second pole post hole 213 and the pin assembly 124 on the plug plate 128.

[0043] Furthermore, the first cover plate 11, the second cover plate 126 and the corresponding positions of the first pole post 121, the second pole post 122 and the pin assembly 124 are provided with through holes, so that the wires can be connected to the first pole post 121, the second pole post 122 and the pin assembly 124.
[0044] In specific implementation, the insert plate 128 is also provided with a third step hole for installing the first guide post 123 and the second guide post 125. The first guide post 123 and the second guide post 125 are provided with a second limiting boss for cooperating with the third step hole to limit and prevent the first guide post 123 and the second guide post 125 from falling off.

[0047] Example 2 An electrical device includes a battery connector with the above-described flexible orientation.
[0048] Compared with existing technologies, this utility model has the following beneficial effects: 1. In existing technologies, connectors typically only allow mating at specific angles, such as forward or reverse, failing to meet multi-angle connection requirements. This solution uses the first pole as the turning center, evenly distributing several second pole holes, pin holes, and guide holes around the first pole hole. This allows the male connector to achieve precise mating with the female connector at multiple angles (such as 30°, 60°, 90°, etc.), overcoming the limitation of only being able to plug in two directions. It is particularly suitable for scenarios such as automated charging equipment and multi-directional charging interfaces.
[0049] 2. In existing technologies, when a battery undergoes slight displacement due to vibration or external forces, it is prone to poor contact between the male and female terminals, affecting connection stability and service life, which is particularly evident in scenarios such as the bumpy ride of an electric bicycle. In this solution, the guide post and the first electrode post are symmetrically positioned, and the first electrode post uses a larger radius as the central post, which can reduce the offset amplitude of vibration; at the same time, the power pins (first electrode post and second electrode post) are distributed close to the turning center, resulting in a smaller radius of arc of the movement trajectory during insertion and removal, and more uniform contact pressure with the corresponding holes, which can reduce wear between the electrode post and the hole wall, and significantly improve the stability of high current transmission and structural durability.
[0050] 3. In existing technologies, under high-current transmission scenarios, uneven contact pressure between the electrode and the hole can lead to increased resistance and even cause safety hazards such as overheating. In this solution, the first and second electrodes, as core conductive components, are designed close to the turning center to reduce alignment errors caused by angular deviations, ensure uniform contact pressure, further guarantee the reliability of power transmission, and reduce safety hazards.
[0051] 4. In existing technologies, a fixed connection orientation often makes it difficult to quickly align the male and female terminals, increasing the workload for users, especially for heavy battery components. In this solution, guide pin holes are evenly distributed around the first electrode hole, and their number corresponds to the second electrode hole. The guide pins of the male connector can cooperate with different guide pin holes depending on the insertion angle, forming a guiding mechanism adapted to the positioning of the power pins. Even at non-positive / reverse angles, the position can be quickly corrected through the cooperation of the guide pins and corresponding guide pin holes, reducing repeated adjustments by the user and improving the user experience.
[0052] 5. When the battery undergoes slight displacement due to vibration, external force, etc., the guide post and the first pole post form a symmetrical orientation. At the same time, by using the larger radius of the first pole post as the central post, the displacement amplitude of the vibration can be reduced, thereby improving the stability and lifespan of the connection in scenarios such as the bumpy ride of an electric bicycle.
[0053] 6. The solution in this application uses the first terminal as the turning center, and the distribution of the power pins (first terminal and second terminal) is closer to the turning center. This results in a smaller radius of curvature for the movement trajectory during insertion and removal, and more uniform contact pressure with the corresponding holes. This reduces wear between the terminal and the hole wall, improving the stability of high-current transmission and structural durability. Simultaneously, the design of the first and second terminals, as core conductive components, being close to the turning center reduces alignment errors caused by angular deviations, further ensuring the reliability of power transmission.
[0054] 7. In this application, the guide pin holes are evenly distributed around the first electrode pin hole, and their number corresponds to the second electrode pin hole. The male connector's guide pins can cooperate with different guide pin holes depending on the insertion angle, forming a guiding mechanism adapted to the positioning of the power connector pins. This design allows the guiding function to work in tandem with the turning center of the power connector pins. Even at non-positive / reverse angles, the position can be quickly corrected through the cooperation of the guide pins and corresponding guide pin holes, reducing the need for repeated adjustments by the user. This is especially beneficial for heavier battery components, significantly reducing operational intensity and improving the user experience.
