[0019] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0020] In the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] Example 1: Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A hole potential transfer microcapacitor for an energy storage battery comprises a shell 1, a core bag 2 is arranged inside the shell 1, an anode guide pin 21 and a cathode guide pin 22 are arranged on the core bag 2, a top cover 11 is connected to the top of the shell 1, and an insertion hole 12 and an insertion hole 2 13 which fit the anode guide pin 21 are respectively opened on the top cover 11.

[0022] Reference Figure 2, further comprising a support plate 3 fitted with the inner wall of the shell 1, the bottom of the core package 2 is fitted on the support plate 3, an annular fixing plate 31 fixedly connected to the inner wall of the shell 1 is provided above the support plate 3, an elastic member is provided between the annular fixing plate 31 and the support plate 3, the elastic member comprises a plurality of vertical protective plates 4 which are circumferentially and fixedly connected to the top of the support plate 3, a top plate 41 is fixedly connected to the top of the vertical protective plate 4, an elastic sheet 42 which contacts the surface of the core package 2 is fixedly connected to one side of the top plate 41, and a plurality of top plates 41 are fixedly connected to the bottom of the annular fixing plate 31. A first spring 43 is fixedly connected, a plurality of guide wheels 32 are provided below the bottom of the support plate 3, a pair of vertical mounting plates 34 are fixedly connected to the bottom of the support plate 3, a connecting shaft 35 is rotatably provided between the two vertical mounting plates 34, the guide wheel 32 is fixedly connected to the connecting shaft 35, a toggle shaft 33 is rotatably provided on the outer shell 1, a toggle member linked to the surface of the guide wheel 32 is fixedly connected to the toggle shaft 33, the toggle member includes a toggle plate 36 fixedly connected to the toggle shaft 33, and an arcuate toggle plate 1 37 and an arcuate toggle plate 2 38 are respectively fixedly connected to the toggle plate 36.

[0023] In the above technical solution, when the dial 36 contacts the surface of the guide wheel 32, the anode guide pin 21 and the cathode guide pin 22 are aligned with the top of the top cover 11 respectively. This design, on the one hand, enables the anode guide pin 21 and the cathode guide pin 22 to be hidden inside the housing 1 during transportation or storage of the capacitor, thereby avoiding the anode guide pin 21 and the cathode guide pin 22 from being squeezed, hit or otherwise subjected to external forces such as protrusion from the top of the housing 1, thereby effectively preventing the anode guide pin 21 and the cathode guide pin 22 from being bent or broken, thereby ensuring the integrity and performance of the capacitor. On the other hand, in conventional In the design, if the anode guide pin 21 and the cathode guide pin 22 are directly exposed to the outside of the shell 1, they will easily become attachment points for dust and other tiny particles. These attachments may not only affect the electrical connection between the guide pins, resulting in a decrease in capacitance performance, but may also cause a short circuit due to the formation of a conductive path, further damaging the function of the capacitor. Therefore, when the anode guide pin 21 and the cathode guide pin 22 are not in use, they are hidden inside the shell 1, which greatly reduces the direct contact between the anode guide pin 21 and the cathode guide pin 22 and the external environment, thereby reducing the risk of dust and other contaminants adhering.

[0024] Reference Figure 3 and Figure 4When the toggle plate 36 is disengaged by rotating along the surface of the guide wheel 32 through the toggle shaft 33, the arc toggle plate 1 37 contacts the surface of the guide wheel 32, and the anode guide pin 21 and the cathode guide pin 22 protrude from the top of the top cover 11 by the same first length, which is used for some electronic devices or application scenarios that do not require high pin height. When the toggle shaft 33 continues to drive the arc toggle plate 1 37 on the toggle plate 36 to rotate along the surface of the guide wheel 32, the arc toggle plate 2 38 contacts the surface of the guide wheel 32, and the anode guide pin 21 and the cathode guide pin 22 protrude from the top of the top cover 11 by the same second length, and the second length is greater than The first length is used for electronic devices or application scenarios that require a higher pin height to ensure good electrical connection and performance. This design avoids the versatility and adaptability issues of capacitors in different electronic devices or application scenarios. In the past, capacitors may need to be customized for different application scenarios, which not only increases production costs and time, but also limits the application scope of capacitors. Now, through this design of adjustable heights of the anode guide pin 21 and the cathode guide pin 22, capacitors can be more flexibly adapted to different electronic devices or application scenarios, greatly reducing the cost and time of customized design.

[0025] It should be noted that, since the core package 2 is clamped between a plurality of elastic sheets 42, when the arc-shaped toggle plate 1 37 or the arc-shaped toggle plate 2 38 on the toggle plate 36 contacts the surface of the guide wheel 32, the guide wheel 32 will be pressed upward by the arc-shaped toggle plate 1 37 or the arc-shaped toggle plate 2 38, so that the vertical mounting plate 34 connected to the connecting shaft 35 drives the support plate 3 to slide along the inner wall of the shell 1, thereby squeezing the first spring 43. As the support plate 3 slides and the top plate 41 squeezes the first spring 43, the anode guide pin 21 and the cathode guide pin 22 on the core package 2 will pass through the corresponding insertion holes, respectively. One 12 and the interpenetrating hole two 13 gradually protrude from the outside of the housing 1, and when the arc-shaped toggle plate one 37 contacts the guide wheel 32, the first protruding length of the anode guide needle 21 and the cathode guide needle 22 reaches a first predetermined value, which is suitable for electronic equipment or application scenarios that do not require high pin height. When the arc-shaped toggle plate two 38 contacts the guide wheel 32, due to further squeezing and adjustment, the second protruding length of the anode guide needle 21 and the cathode guide needle 22 will increase to a second predetermined value, which is greater than the first predetermined value, and is suitable for electronic equipment or application scenarios that require a higher pin height.

[0026] Example 2: Reference Figure 5 , Figure 6 and Figure 7On the basis of the above embodiment, the difference is that a plurality of exhaust holes 39 are opened on the support plate 3, a circular block 310 corresponding to the exhaust hole 39 is fixedly connected to the connecting shaft 35, a plurality of arc-shaped protrusions 311 are fixedly connected to the circular block 310, and a resistance member located between the top and the bottom of the support plate 3 and linked with the circular block 310 and the arc-shaped protrusion 311 is provided in the exhaust hole 39, and the resistance member includes an annular connecting rod 312 located above the top of the support plate 3, and a plurality of circumferential resistance members that are all attached to the top of the support plate 3 are fixedly connected to the annular connecting rod 312. The contact block 313 has two contact blocks 313 whose bottoms are fixedly connected with a contact rod 314 extending along the bottom of the exhaust hole 39. The end of the contact rod 314 located below the exhaust hole 39 is fixedly connected with a limiting block 315. The surface of the contact rod 314 is sleeved with a second spring 316 fixedly connected between the top of the limiting block 315 and the bottom of the support plate 3. The bottom of the limiting block 315 is fixedly connected with a fitting block 317 in contact with the surface of the circular block 310. The fitting block 317 is semicircular in shape. The end diameter of the contact rod 314 is smaller than the inner wall diameter of the exhaust hole 39.

[0027] In the above technical solution, when the dial 36 contacts the guide wheel 32, the anode guide pin 21 and the cathode guide pin 22 on the core package 2 are hidden inside the housing 1, that is, when the capacitor is not in use, the two abutment blocks 313 located on the top of the support plate 3 cover the exhaust hole 39, such as Figure 7 As shown, this can prevent dust or moisture from entering the corresponding chamber space on the top of the support plate 3 through the exhaust hole 39, causing problems such as electrical performance degradation, short circuit or corrosion of the core package 2.

[0028] When the arc-shaped toggle plate 1 37 or the arc-shaped toggle plate 2 38 is in the process of abutting against the guide wheel 32, the anode guide pin 21 and the cathode guide pin 22 on the core package 2 are protruding from the outside of the shell 1, indicating that the capacitor is in use. At the same time, the guide wheel 32 will drive the circular block 310 on the connecting shaft 35 to rotate together under the rotational abutment of the arc-shaped toggle plate 1 37 or the arc-shaped toggle plate 2 38. As the circular block 310 rotates, the arc-shaped protrusion 311 fixed on the circular block 310 will also rotate and gradually abut against the surface of the fitting block 317, thereby pushing the limit block 315 to squeeze the second spring 316, so that the abutment rod 314 drives the abutment block 310 on the annular connecting rod 312 to rotate. 13 abuts between the vertical protective plate 4 and the elastic sheet 42. Such a design has the following advantages: firstly, when the abutment block 313 is separated from the exhaust hole 39, since the end diameter of the abutment rod 314 is smaller than the inner wall diameter of the exhaust hole 39, the heat generated by the core package 2 when working inside the shell 1 can be smoothly introduced into the bottom of the support plate 3 through the exhaust hole 39, and finally discharged from the holes at the bottom of the shell 1, thereby improving the heat dissipation effect of the capacitor; secondly, the abutment block 313 abuts between the vertical protective plate 4 and the elastic sheet 42, which can further increase the clamping effect of the multiple elastic sheets 42 on the core package 2, so that the core package 2 can remain stable during operation and reduce the risk of performance degradation or damage caused by vibration or external interference.

[0029] Example 3: Reference Figure 8 and Fig. 9 On the basis of the above embodiment, the difference is that a circular rotating block 318 is fixedly connected to one end of the toggle shaft 33 located in the shell 1, and a threaded limiting groove 319 is opened on the circular rotating block 318. A plurality of locking parts distributed in a circle are arranged around the circular rotating block 318. The locking part includes a positioning plate 320 fixedly connected to the shell 1, and a locking screw 321 is threadedly connected to the positioning plate 320. One end of the locking screw 321 is used to cooperate with the threaded limiting groove 319 for locking, and the other end of the locking screw 321 is fixedly connected to a hexagonal driving block 322.

[0030] In the present technical solution, there are three positioning plates 320, and the three positioning plates 320 are distributed in a circle around the circular rotating block 318. When the toggle shaft 33 drives the toggle plate 36, the arc toggle plate 1 37 or the arc toggle plate 2 38 to rotate, the user only needs to simply rotate the threaded limit groove 319 provided on the circular rotating block 318 to a position corresponding to any one of the positioning plates 320, and then operate the hexagonal driving block 322 to rotate the locking screw 321 on the positioning plate 320 to tightly lock the thread. Tightly fitted into the inner wall of the threaded limit groove 319, on the one hand, this can improve the fixing stability of the toggle plate 36, the arc-shaped toggle plate 1 37 or the arc-shaped toggle plate 2 38 when they are in contact with the guide wheel 32; on the other hand, through the corresponding locking relationship between the threaded limit groove 319 on the circular rotating block 318 and each positioning plate 320, the user can intuitively identify the specific position where the toggle plate 36, the arc-shaped toggle plate 1 37 or the arc-shaped toggle plate 2 38 is currently in contact with the guide wheel 32, thereby greatly simplifying the operation process and improving work efficiency.

[0031] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of them belong to the protection scope of the present invention.
