Description

Technical Field

[0001] This application relates to the technical field of connection cables, and specifically, to parallel connection cables.

Background Art

[0002] Energy storage power sources can be connected to electrical devices to supply power to the electrical devices. Considering high-power electrical devices, a higher-output energy storage power source is often required. However, a relatively high-output energy storage power source has a large mass and volume, making it inconvenient for portability and transportation. Therefore, by connecting two adjacent energy storage power sources using a parallel connection cable, at least two energy storage power sources can operate in parallel, thereby providing a higher output to the electrical device and meeting the needs of the electrical device.

[0003] In the related technical field, since the sizes of energy storage power sources that require parallel operation are different, if the positional relationship between the conducting wire of the parallel connection cable and the plug of the parallel connection cable is fixed, the connection segment where the conducting wire and the plug are connected is prone to fatigue damage, the parallel connection cable is damaged, the parallel operation of the energy storage power source becomes unstable, and it affects the user's usage needs.

Summary of the Invention

[0004] Embodiments of this application provide a parallel connection cable. The purpose is to utilize the movable connection between the movable member and the plug body to avoid the direct rigid fixation of the conducting wire to the plug body, and further effectively solve the problem of breakage due to fatigue of the conducting wire, ensure that a larger output power can be supplied to the electrical device by the parallel operation of the energy storage power source, and meet the user's usage needs.

[0005] Embodiments of the present invention provide a parallel connection cable. The parallel connection cable includes a plug and a conductor, the plug including a plug body connected to an energy storage power source, a movable member movably connected to the plug body so as to be movable relative to the plug body, and a position limiting member provided between the movable member and the plug body to restrict the movement of the movable member relative to the plug body, the conductor including a connecting segment connected to the movable member, the connecting segment being further electrically connected to an energy storage power source via the plug body, and the movable member being movable relative to the plug body so as to move the connecting segment following the movable member.

[0006] Based on the parallel connection cable of this invention, by utilizing a movable connection between the movable member and the plug body, the connection segment can move in accordance with the movable member, thus avoiding the direct and rigid fixing of the conductor to the plug body. Furthermore, this effectively solves the problem of conductor breakage due to fatigue, stabilizes the parallel operation of energy storage power sources, ensures that greater output power can be supplied to electrical equipment through the parallel operation of energy storage power sources, and meets the user's needs.

[0009] To further clarify the purpose, technical means, and advantages of this application, the application will be described in more detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are for interpretive purposes only and do not limit the application.

[0010] As shown in Figure 1, an embodiment of the present invention provides a parallel connection cable 1 including a plug 2 and a conductor 3.

[0011] Plug 2 includes a plug body 21 connected to an electronic device, and a movable member 22 that is movable relative to the plug body 21.

[0012] The conductor 3 includes a connecting segment 31, which is connected to a movable member 22 and further electrically connected to an energy storage power source by the plug body 21.

[0013] In the embodiment of the present invention, by utilizing a movable connection between the movable member 22 and the plug body 21, the movable member 22 can move relative to the plug body 21, thereby avoiding the direct and rigid fixing of the conductor 3 to the plug body 21, effectively solving the problem of conductor 3 breaking due to fatigue, and extending the service life of the parallel connection cable 1.

[0014] The electronic devices include energy storage power supplies, mobile phones, smartwatches, tablet computers, and laptop computers. By connecting any two of these devices via the parallel connection cable 1, electrical energy transmission or data transmission between the electronic devices can be achieved. In other embodiments, the electronic devices may take on other forms. The specific form of the electronic devices is not limited in the embodiments of this application.

[0015] The movable connection method between the movable member 22 and the plug body 21 includes rotary connection, locking, and ball joint, all of which allow the angle between the movable member 22 and the plug body 21 to be changed, thereby reducing the actual curvature angle and width of the connection segment 31. In other embodiments, the movable connection method between the movable member 22 and the plug body 21 may take other forms. In the embodiments of the present application, the specific form of the movable connection method between the movable member 22 and the plug body 21 is not limited.

[0016] For example, when the movable member 22 and the plug body 21 are movably connected in a locking manner, the plug body 21 may be provided with a plurality of locking grooves (not shown) at intervals, and the plug 2 may include a locking member (not shown), which is provided on the movable member 22 and can selectively lock into one locking groove, thereby enabling a movable connection between the movable member 22 and the plug body 21. The locking member may also be provided on the plug body 21, and the movable member 22 may be provided with a plurality of locking grooves at intervals, and the locking member can selectively lock into one locking groove, similarly enabling a movable connection between the movable member 22 and the plug body 21.

[0017] For example, if the movable member 22 and the plug body 21 are movably connected in the form of a ball joint, the plug body 21 is provided with a ball socket (not shown), and the plug 2 includes a ball head (not shown), the ball head is provided on the movable member 22 and rotatably mounted within the ball socket, thereby realizing a movable connection between the movable member 22 and the plug body 21. The ball socket may be provided on the movable member 22, and the head ball may be provided on the plug body 21, and similarly, a movable connection between the movable member 22 and the plug body 21 can be realized by providing the ball head rotatably within the ball socket.

[0018] In addition, the parallel connection cable 1 may include two plugs 2, each connected to both ends of the conductor 3, thereby allowing connection to two electronic devices. In another embodiment, the parallel connection cable 1 may include only one plug 2, with one end of the conductor 3 directly connected to an electronic device and the other end connected to the plug 2, thereby connecting to another electronic device.

[0019] As shown in Figure 1, in a specific embodiment, the electronic device may include an energy storage power supply, which is connected to the electrical device and can supply power to the electrical device. When considering high-power electrical devices, a higher-power energy storage power supply is often required, but relatively high-power energy storage power supplies are inconvenient to carry and transport because they are large in both mass and volume. Therefore, by connecting two adjacent energy storage power supplies using a parallel connection cable 1, at least two energy storage power supplies can be operated in parallel, thereby supplying higher output to the electrical device and thus meeting the needs of the electrical device.

[0020] However, because the energy storage power sources operating in parallel are of different sizes, designing different parallel connection cables 1 for the parallel requirements of different energy storage power sources results in a large number of types of parallel connection cables 1, which significantly increases the parallelization cost.

[0021] When the relative positions of the conductor 3 and the plug 2 are fixed, the twisting or bending of the connection segment 31 increases, making the connection segment 31 more susceptible to damage, which in turn damages the parallel connection cable 1, leading to unstable parallel operation of the energy storage power supply and affecting the user's needs.

[0022] For example, when the angle between the conducting wire 3 and the plug 2 is fixed at 180° and both ends of the parallel connection cable 1 are connected to two energy storage power sources at distant positions, the connection segment 31 tends to bend at 90°, or the torsional width becomes large, making the parallel connection cable 1 prone to damage. When the angle between the conducting wire 3 and the plug 2 is fixed at 90° and both ends of the parallel connection cable 1 are connected to two energy storage power sources at close positions, similarly, the connection segment 31 tends to bend at 90°, or the torsional width becomes large, and similarly, the parallel connection cable 1 is prone to damage.

[0023] Based on this, similarly, by utilizing the movable connection between the movable member 22 and the plug body 21, the position of the movable member 22 can be adjusted according to different connection needs, so that the connection segment 31 can move following the movable member 22, making the connection segment 31 less likely to be damaged, effectively preventing the breakage problem caused by fatigue or wear of the conducting wire 3, further stabilizing the parallel operation of the energy storage power sources, ensuring that a larger output power can be supplied to electrical equipment through the parallel operation of the energy storage power sources, and meeting the usage needs of users.

[0024] In addition, since the movable member 22 is movable relative to the plug body 21, when the energy storage power sources operate in parallel, the position of the movable member 22 can be adjusted according to the requirements for wire arrangement, thereby improving the overall aesthetics during the parallel operation of the energy storage power sources.

[0025] As shown in FIG. 1, in one embodiment, the plug body 21 has an insertion / removal direction X for insertion / removal with respect to the energy storage power supply. In the process of the movable member 22 moving with respect to the plug body 21, the angle R1 formed with the insertion / removal direction X satisfies 0° ≦ R1 ≦ 90°, so that a large movement range can be provided for the connection segment 31. Thereby, the breakage probability of the connection segment 31 can be reduced, and the service life of the parallel connection cable 1 can be extended. In the actual manufacturing process, the numerical range of the angle R1 can be adjusted according to actual usage needs in order to reduce manufacturing costs. Exemplarily, the angle R1 can satisfy 50° ≦ R1 ≦ 80°. Naturally, the angle R1 can further satisfy 30° ≦ R1 ≦ 70°. In other embodiments, the angle R1 can satisfy other numerical ranges. In the embodiments of the present application, the numerical range of the angle R1 is not particularly limited.

[0026] As shown in FIGS. 1 and 2, in one embodiment, the plug 2 includes a rotation axis 23, and the movable member 22 is rotatably connected to the plug body 21 via the rotation axis 23. By providing a stable rotation fulcrum for the movable member 22 and the plug body 21 by the rotation axis 23, the movement locus of the movable member 22 can be controllably made, and it is ensured that the direction of the connection segment 31 and the rotation direction of the movable member 22 coincide, thereby preventing breakage of the connection segment 31. Further, by connecting the movable member 22 and the plug body 21 using the rotation axis 23, a connection with a small gap and high rigidity between the movable member 22 and the plug body 21 can be realized, while ensuring the flexibility of the rotation of the movable member 22 and reducing the probability of loosening or dropping between the movable member 22 and the plug body 21. Thereby, the connection stability between the movable member 22 and the plug body 21 can be increased.

[0027] As shown in Figures 1-3, specifically, the plug body 21 has a housing cavity 211A and a wire passage opening 211B that communicate with each other, and the movable member 22 includes a connecting portion 221 and an extending portion 222. The connecting portion 221 is located inside the housing cavity 211A and is rotatably connected to the plug body 21 via a rotating shaft 23, and the extending portion 222 is connected to the connecting portion 221 and extends outside the housing cavity 211A through the wire passage opening 211B, and the conductor 3 is connected to the extending portion 222 and inserted into the wire passage opening 211B, thereby enabling electrical connection to the plug body 21.

[0028] Furthermore, the conductor 3 can be electrically connected to the plug body 21 by being inserted into the housing cavity 211A, passing through the extended portion 222 and the connecting portion 221. In other embodiments, the conductor 3 is inserted into the connecting portion 221 and can be electrically connected to the connecting portion 221. In this case, since the connecting portion 221 can be electrically connected to the plug body 21, the conductor 3 can similarly be electrically connected to the plug body 21. The specific structure will not be described here.

[0029] As shown in Figures 2 and 3, in one embodiment, the connecting portion 221 has a shielding surface 221A facing the wire passage opening 211B, and the extending portion 222 is connected to the shielding surface 221A. The orthographic projection of the shielding surface 221A onto the surface where the wire passage opening 211B is located covers the wire passage opening 211B, thereby preventing external foreign matter from passing through the wire passage opening 211B and entering the housing cavity 211A. This reduces the probability of the rotating shaft 23 getting stuck and ensures that the connecting portion 221 rotates smoothly relative to the plug body 21. Furthermore, by reducing the probability of external foreign matter adhering to the electronic components in the housing cavity 211A, the probability of damage to the electronic components can be reduced, and the service life of the parallel connection cable 1 can be extended.

[0030] Furthermore, since the orthographic projection of the shielding surface 221A onto the surface where the wire passage opening 211B is located covers the wire passage opening 211B, when the movable member 22 rotates, the shielding surface 221A always covers the wire passage opening 211B, further reducing the probability of external impurities entering the housing cavity 211A.

[0031] Furthermore, the plug 2 further includes a cover member (not shown), which is provided between the shielding surface 221A and the inner wall of the housing cavity 211A. By covering the gap between the shielding surface 221A and the inner wall of the housing cavity 211A, a dynamic cover structure is formed, which can effectively prevent external foreign matter from passing through the wire passage opening 211B and entering the inside of the housing cavity 211A, further protecting the rotating shaft 23 and electronic components and extending the service life of the parallel connection cable 1.

[0032] Furthermore, when the movable member 22 rotates relative to the plug body 21, the deformation caused by the cover member absorbs mechanical vibrations during the rotation process, reducing the probability of collision noise between the plug body 21 and the movable member 22, and improving the user experience.

[0033] For example, the cover member is connected to the inner wall of the housing cavity 211A and is provided around the periphery of the wire passage opening 211B, and can abut against the shielding surface 221A. Naturally, the cover member may also be provided on the shielding surface 221A and abut against the inner wall of the housing cavity 211A. In other embodiments, the cover member may be provided simultaneously on the inner wall of the housing cavity 211A and the shielding surface 221A, but this will not be described here.

[0034] The cover member may also include felt or foam. In other embodiments, the cover member may also be made of other flexible materials such as silicone or rubber. The specific form of the cover member is not limited in the embodiments of the present application.

[0035] After the movable member 22 has moved relative to the plug body 21 and been adjusted, the plug 2 further includes a position limiting member (not shown) to prevent the movable member 22 from continuing to move, the position limiting member is provided between the movable member 22 and the plug body 21, and can restrict the movement of the movable member 22 relative to the plug body 21 and further prevent the reciprocating motion of the movable member 22 relative to the plug body 21, thereby further reducing the probability of significant bending of the connection segment 31 and improving the connection stability between the plug 2 and the energy storage power source.

[0036] For example, the position limiting member may include a damping member (not shown), which is provided on the plug body 21 and can contact the movable member 22. Because the frictional force between the damping member and the movable member 22 is large, the rotation of the movable member 22 relative to the plug body 21 can be restricted. Naturally, the damping member may also be provided on the movable member 22 and can contact the plug body 21, but this will not be explained here. In other embodiments, the plug body 21 and the movable member 22 may be designed to be tightly fitted together, thereby restricting the rotation of the movable member 22 relative to the plug body 21 due to the frictional resistance between the plug body 21 and the movable member 22.

[0037] The position limiting member further includes a projection (not shown) provided on the plug body 21, and the movable member 22 is provided with a plurality of grooves (not shown). When the movable member 22 rotates until the inner wall of any groove contacts a projection, the engagement between the projection and the groove can restrict further rotation of the movable member 22 relative to the plug body 21. Naturally, the projection may be provided on the movable member 22, and the plug body 21 is provided with a plurality of grooves. Similarly, when the movable member 22 rotates until the inner wall of any groove contacts a projection, the engagement between the projection and the groove can similarly restrict further rotation of the movable member 22 relative to the plug body 21. In other embodiments, the position limiting member may take other forms. In the embodiments of the present application, the specific form of the position limiting member is not limited.

[0038] As shown in Figures 1-3, in one embodiment, the plug body 21 includes a housing 211 and a connection terminal 212, the housing 211 being movably connected to a movable member 22, and the connection terminal 212 being electrically connected to a conductor 3 and partially exposed from the housing 211.

[0039] The housing 211 may be made of plastic to protect the components inside, thereby reducing the probability of component damage, which in turn extends the service life of the plug body 21 and the parallel connection cable 1. Furthermore, the housing 211 can have high structural strength through integral injection molding, which in turn reduces the probability of damage to the housing 211 and provides good protection for the components inside the housing 211.

[0040] The connection terminal 212 is inserted into the terminal of the energy storage power supply to establish an electrical connection between the parallel connection cable 1 and the energy storage power supply. Exemplarily, the connection terminal 212 includes at least one of the following: a circular connector terminal, a USB terminal, or a Lightning terminal. Note that if the connection terminal 212 is a male terminal, the terminal of the energy storage power supply is a female terminal that mates with the male terminal; and if the connection terminal 212 is a female terminal, the terminal of the energy storage power supply is a male terminal that mates with the female terminal.

[0041] When the plug body 21 is ball-jointed with the movable member 22, one of the ball head and ball socket is connected to the housing 211, and the other of the ball head and ball socket is connected to the movable member 22, which will not be explained further here.

[0042] As shown in Figures 1, 3-5, in order to further improve the safety of inserting and removing the plug body 21, the plug body 21 further includes an operating member 214 and a trigger member 215. The operating member 214 is slidably connected to the housing 211 and partially exposed from the housing 211. The trigger member 215 is provided in the sliding path of the operating member 214 and, when triggered by the operating member 214, transmits an electrical signal to the energy storage power supply, allowing the energy storage power supply to perform in-position detection on the connection terminal 212. When the energy storage power supply detects that the connection terminal 212 is about to be removed, it stops supplying power to another energy storage power supply in parallel operation, thereby reducing the probability of arc discharge between the connection terminal 212 and the energy storage power supply and improving the safety of the energy storage power supply.

[0043] For example, the connection terminal 212 may include an electrical transmission pin and an in-position detection pin. Since the length of the in-position detection pin is shorter than the length of the electrical transmission pin, in the process of the connection terminal 212 being removed, the in-position detection pin detaches from the energy storage power supply before the electrical transmission pin. This allows the energy storage power supply to detect that the connection terminal 212 is about to be removed. At this time, the energy storage power supply controls the electrical transmission pin to stop power transmission, thereby achieving electrical isolation between the connection terminal 212 and the energy storage power supply.

[0044] As shown in Figures 1 and 3, in order to improve the stability of the electrical connection between the connection terminal 212 and the energy storage power supply, the plug body 21 further includes a locking assembly 213, the locking assembly 213 being rotatably connected to the housing 211 and partially exposed from the housing 211, and when the connection terminal 212 is connected to the energy storage power supply, the locking assembly 213 can lock with the energy storage power supply, thereby reducing the probability of the connection terminal 212 becoming detached from the energy storage power supply, further ensuring the electrical connection between the connection terminal 212 and the energy storage power supply, and improving the safety of the parallel connection cable 1.

[0045] Specifically, by connecting two energy storage power supplies via the parallel connection cable 1, when the two energy storage power supplies are operated in parallel, the locking assembly 213 can lock onto the housing of the energy storage power supplies, thereby reducing the probability of the plug 2 becoming detached from the energy storage power supply. This further improves the stability of the parallel operation of the energy storage power supplies, ensuring that the parallel operation of the energy storage power supplies can supply greater output power to electrical equipment and meet the user's needs.

[0046] Furthermore, because the connection between plug 2 and the energy storage power supply is stable, the probability of plug 2 becoming detached from the energy storage power supply when organizing the wires is reduced, thereby reducing the need for repeated insertion work and improving the efficiency of wire organization.

[0047] The engagement assembly 213 is located in the sliding path of the operating member 214. When it is necessary to remove the plug 2, the engagement between the engagement assembly 213 and the energy storage power supply can be released by driving the operating member 214 to operate the engagement assembly 213, and the plug 2 can then be removed along the insertion / removal direction X.

[0048] As shown in Figures 1, 3-5, in one embodiment, the housing 211 has an opening 211C that communicates with the housing cavity 211A, and the operating member 214 includes a drive unit 2141 and a driven unit 2142, the drive unit 2141 being exposed from the opening 211C, and the driven unit 2142 being connected to the drive unit 2141, provided in the housing cavity 211A, and slidably connected to the housing 211. When the drive unit 2141 slides a first distance L1 into the housing cavity 211A from its initial position, the driven unit 2142 triggers a trigger member 215, and when the drive unit 2141 slides a second distance L2 into the housing cavity 211A from its initial position, the driven unit 2142 drives the engagement assembly 213 to rotate in order to release engagement with the energy storage power source, the second distance L2 being greater than or equal to the first distance L1.

[0049] When the user needs to remove plug 2, the drive unit 2141 is pressed, causing it to move a first distance L1 into the housing cavity 211A from its initial position. At this time, the driven unit 2142 slides a first distance L1, triggering the trigger member 215, which can send an electrical signal to the energy storage power supply. Upon receiving the electrical signal, the energy storage power supply performs in-position detection with respect to the connection terminal 212. If the user continues to press the drive unit 2141 so that the driven unit 2142 slides a second distance L2, the driven unit 2142 drives the locking assembly 213 to rotate, releasing the locking assembly 213 from the energy storage power supply, allowing the user to pull out plug 2 along the insertion / removal direction X. If the energy storage power supply detects that the connection terminal 212 is about to be disconnected, it stops supplying power to another energy storage power supply operating in parallel, thereby reducing the probability of arc discharge between the connection terminal 212 and the energy storage power supply and improving the safety of the energy storage power supply.

[0050] The process described above avoids temporary current shocks caused by "hot-plugging," protects the energy storage power supply and parallel connection cable 1 from high-voltage damage, reduces the probability of damage to the energy storage power supply and parallel connection cable 1, extends the service life of the energy storage power supply and parallel connection cable 1, and improves the safety of the energy storage power supply.

[0051] As shown in Figures 1, 3-5, in one embodiment, the engagement assembly 213 and the trigger member 215 are provided on two opposing inner walls of the housing cavity 211A, respectively. The driven part 2142 includes a first sub-driven part 2143 and a second sub-driven part 2144. The first sub-driven part 2143 is connected to the drive unit 2141 and slidably connected to the inner wall of the housing cavity 211A, and when it moves a first distance L1 from its initial position, it triggers the trigger member 215. The second sub-driven part 2144 is connected to the drive unit 2141 and is provided opposite to the first sub-driven part 2143, and slidably connected to the inner wall of the housing cavity 211A, and when it moves a second distance L2, it drives the engagement assembly 213 to rotate.

[0052] Specifically, the first sub-driven part 2143 and the second sub-driven part 2144 may be provided symmetrically along the central axis of the housing cavity 211A, thereby equalizing the force received between the drive unit 2141, the first sub-driven part 2143, and the second sub-driven part 2144, reducing the probability of sliding deflection and jamming between the first sub-driven part 2143 and the second sub-driven part 2144, improving the comfort of the user when pressing the drive unit 2141, and also allowing the first sub-driven part 2143 to trigger the trigger member 215 and the second sub-driven part 2144 to trigger the engagement assembly 213 when the user presses the drive unit 2141, and further ensuring that the plug 2 can be pulled out while achieving electrical isolation between the plug 2 and the energy storage power source.

[0053] Furthermore, since the engagement assembly 213 and the trigger member 215 are provided on two opposing inner walls of the housing cavity 211A, the movement trajectories of the first sub-driven part 2143 and the second sub-driven part 2144 do not intersect, thereby reducing the probability of interference or false triggering.

[0054] The trigger member 215 includes a microswitch 2151, and a pressing surface 2143A is provided on the side of the first sub-driven unit 2143 away from the drive unit 2141 to press against the microswitch 2151. When the pressing surface 2143A contacts the microswitch 2151, the microswitch 2151 can transmit an electrical signal to the energy storage power source.

[0055] Naturally, the trigger member 215 includes a photoelectric sensor (not shown), and a light-shielding sheet is provided on the side of the first sub-driven unit 2143 away from the drive unit 2141. When the light-shielding sheet moves to the receiving optical path of the photoelectric sensor by the drive of the first sub-driven unit 2143, the photoelectric sensor can transmit an electrical signal to the energy storage power supply.

[0056] In other embodiments, the trigger member 215 may take on other forms, and the specific form of the trigger member 215 is not limited in the embodiments of the present application.

[0057] For example, the method by which the trigger member 215 transmits an electrical signal to the energy storage power source includes at least one of wired transmission, infrared transmission, Bluetooth transmission, NFC (Near Field Communication) transmission, and WIFI (Wireless Network Communication Technology) transmission. In other embodiments, the method by which the trigger member 215 transmits an electrical signal to the energy storage power source may take other forms. In embodiments of the present application, the method by which the trigger member 215 transmits an electrical signal to the energy storage power source is not particularly limited.

[0058] As shown in Figures 1, 3, and 4, in one embodiment, the engagement assembly 213 includes an engagement member 2131 and a first elastic member 2132, the engagement member 2131 being rotatably connected to the housing 211 and having a drive end 2131A and an engagement end 2131C facing each other, the drive end 2131A being located within the housing cavity 211A and situated in the sliding path of the second sub-driven part 2144, the engagement end 2131C being exposed from the housing 211 and used for engagement with the energy storage power supply, and the first elastic member 2132 being connected to the inner wall of the housing cavity 211A and the drive end 2131A.

[0059] When the connection terminal 212 is inserted into the energy storage power supply, the first elastic member 2132 drives the drive end 2131A to rotate along the first direction Y, thereby engaging the engagement end 2131C with the energy storage power supply and reducing the probability of the connection terminal 212 becoming detached from the energy storage power supply.

[0060] When it is necessary to remove plug 2, pressing the drive unit 2141 and moving it by a second distance L2 causes the second sub-driven unit 2144 to move by the second distance L2, driving the drive end 2131A to rotate along the second direction Z, and elastically deforming the first elastic member 2132, thereby releasing the engagement between the engaging end 2131C and the energy storage power supply, and thereby enabling the plug 2 to be pulled out along the insertion / removal direction X, thus achieving the removal of plug 2. The second direction Z is opposite to the first direction Y.

[0061] The first elastic member 2132 may be at least one of a torsion spring, an elastic sheet, and a spring. In other embodiments, the first elastic member 2132 may take other forms. In the embodiments of the present application, the specific form of the first elastic member 2132 is not limited.

[0062] As shown in Figures 1, 3, and 4, one end of the second sub-driven unit 2144 away from the drive unit 2141 has a first guide slope 2144A, and the drive end 2131A has a second guide slope 2131B. The first guide slope 2144A slidably contacts the second guide slope 2131B, causing the drive end 2131A to rotate in the second direction Z, thereby causing the engagement end 2131C to also rotate along the second direction Z, and further releasing the engagement between the engagement end 2131C and the energy storage power source.

[0063] Since the first guide slope 2144A and the second guide slope 2131B are in sliding contact with each other, impact force and wear can be effectively reduced compared to direct rigid collision drive, the rotation of the drive end 2131A can be made smoother, the sticking phenomenon due to wear can be reduced, and the service life of the engagement assembly 213 can be extended.

[0064] Furthermore, the sliding contact of the first guide slope 2144A with the second guide slope 2131B reduces the force required for the second sub-driven part 2144 to drive the drive end 2131A to rotate, making it easier for the drive end 2131A to rotate against the elastic force of the first elastic member 2132. In addition, the user can release the engagement between the engagement end 2131C and the energy storage power source with less force, making user operation easier and improving the user experience.

[0065] As shown in Figures 1, 3, and 4, in order to facilitate the return of the operating member 214, the plug body 21 further includes a second elastic member 216, which is provided in the housing cavity 211A and has both ends connected to the inner wall of the housing cavity 211A and the driven part 2142, respectively. The second elastic member 216 drives the drive unit 2141 to move out of the housing cavity 211A so as to return the operating member 214, that is, to return the drive unit 2141 to its initial position, thereby facilitating the operation of the user to press the drive unit 2141 again to release the engagement between the engagement assembly 213 and the energy storage power supply. It also facilitates the operation of the user to press the drive unit 2141 again to trigger the trigger member 215.

[0066] The second elastic member 216 may be at least one of an elastic sheet and a spring. In other embodiments, the second elastic member 216 may take other forms. In the embodiments of the present application, the specific form of the second elastic member 216 is not limited.
