[0027] In some embodiments, the second flange structure is connected to the first flange structure and the fixing portion respectively.

[0028] By adopting the above-mentioned technical solution, the second flange structure is connected to the first flange structure and the fixing part, so that the output pole in the accommodating cavity can increase the creepage distance between it and the first beam body in the length direction toward the first beam body, or in any direction intersecting with the length direction of the first beam body, and the insulation protection effect is better; at the same time, the first flange structure, the second flange structure and the fixing part can be arranged around the notch of the avoidance groove, thereby improving the sealing effect of the avoidance groove and reducing the probability of metal chips inside the first beam body falling out of the avoidance groove.

[0029] In some embodiments, a ripple structure is formed on a surface of the second flange structure facing the insulation cover.

[0030] By adopting the above technical solution, since creepage occurs along the surface of the insulator, an undulating structure is formed on the second flange structure, which can effectively increase the creepage distance from the output pole to the first beam body and further improve the protection effect of the output pole base.

[0031] In some embodiments, a first limiting portion is formed on the insulating cover, and the first limiting portion is plugged into and matched with the undulating structure.

[0033] In some embodiments, the main body is recessed in the length direction of the first beam to form a clamping groove, and the insulating cover is formed with a clamping portion, which is inserted into the clamping groove.

[0034] By adopting the above technical solution, the clamping portion of the insulation cover is plugged into the clamping groove on the main body so that the clamping groove limits the movement of the clamping portion, thereby maintaining the insulation cover in a state where the cover is arranged on the main body.

[0052] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0053] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0055] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0056] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0057] To increase energy density, batteries are becoming increasingly integrated. Simultaneously, the current trend toward rapid battery charging is toward high-voltage, high-rate charging. However, achieving high battery voltage requires connecting more battery cells in series, which necessitates a larger number of wiring harnesses and wider flexible circuit boards. Furthermore, the high currents generated by high-rate charging require even wider busbars. This compresses the top assembly space of the beam structure within the housing, particularly along the length of the internal beams, significantly impacting the layout of the output pole bases used to mount the positive and negative output poles.

[0058] Based on the above considerations, in order to solve the problem that the top assembly space of the beam structure inside the box is occupied, which affects the assembly of the output pole base, a battery is designed. By opening an avoidance groove on the first beam body of the box body, the main body of the output pole base can be accommodated in the avoidance groove, and the fixing part can be fixed on the first beam body on the side away from the battery module, so that the fixing part can be staggered from the top of the first beam body for assembly, effectively reducing the impact of the top assembly space of the first beam body on the assembly of the output pole base being occupied, and the output pole base can be more conveniently fixed and assembled through the fixing part.

[0059] The battery disclosed in the embodiments of the present application can be used as a power source for electrical devices or as an energy storage element in various energy storage systems. Electrical devices may include, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, battery cars, electric cars, ships, spacecraft, and the like. Among them, electric toys may include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, and spacecraft may include airplanes, rockets, space shuttles, and spacecraft, and the like.

[0085] It can be understood that when the first connection structure 1221 and the second connection structure 1222 are fixedly connected to the first beam body 110 , the third connection structure 1223 will abut against the outer wall surface of the first beam body 110 on the side facing away from the battery module 20 .

[0086] With such an arrangement, when the output pole base 120 is fixedly assembled on the first beam body 110, the first connecting structure 1221 and the second connecting structure 1222 form a fixed connection with the first beam body 110, and the third connecting structure 1223 can abut against the outer wall surface of the first beam body 110, so that the first connecting structure 1221, the second connecting structure 1222 and the third connecting structure 1223 can act together on the first beam body 110, so that the stability of the main body 121 is better; at the same time, the first connecting structure 1221, the second connecting structure 1222 and the third connecting structure 1223 can also block the avoidance groove 111, which can reduce the probability of metal chips inside the first beam body 110 falling out of the avoidance groove 111.

[0087] Please refer to Figures 3 to 5. In some embodiments, the battery 100 also includes a circuit board 30, which is connected to the battery module 20 and fixedly connected to the first beam 110; wherein the circuit board 30 and the fixing portion 122 are respectively connected to different sides of the first beam 110.

[0088] It can be understood that the circuit board 30 is fixedly connected to the first beam body 110, and the circuit board 30 is specifically fixed to the top of the first beam body 110, that is, the exposed wall surface intersecting with one side of the first beam body 110 facing the battery module 20 and the other side opposite to the battery module 20.

[0089] In this configuration, the circuit board 30 and the fixing portion 122 are respectively connected to different sides of the first beam 110 . Thus, the circuit board 30 occupies the assembly space of the first beam 110 due to its own width, which has little impact on the assembly of the fixing portion 122 .

[0090] 4 to 6 , in some embodiments, the output pole base 120 further includes an insulating cover 130 . The insulating cover 130 covers the main body 121 and forms a receiving cavity 1301 . One end of the output pole 21 is disposed in the receiving cavity 1301 .

[0091] The insulating cover 130 is an insulating structure, such as a cover structure formed of a material such as silicone, rubber, or plastic. The insulating cover 130 can be positioned over the main body 121 to form a receiving cavity 1301 , so that one end of the output pole 21 can be positioned within the receiving cavity 1301 to facilitate connection with the external electrical connection structure 22 .

[0092] Optionally, the insulating cover 130 can be a hollow structure with one end open. The insulating cover 130 is covered on the main body 121 through its open end to form a relatively sealed accommodating cavity 1301, and the output pole 21 and the external electrical connection structure 22 can both be passed through the accommodating cavity 1301 to achieve connection.

[0093] The above-mentioned peripheral electrical connection structure 22 can be a conductive structure such as a guide plate or a guide bar.

[0094] In this configuration, the insulating cover 130 is covered on the main body 121 to form a receiving cavity 1301 , so that the output pole 21 fixed on the main body 121 can be received in the receiving cavity 1301 , effectively improving the protection effect of the output pole 21 .

[0095] Please refer to Figures 4 to 6. In some embodiments, the main body 121 extends in the direction toward the battery module 20 to form a first flange structure 1211, and a first wiring port 1302 for introducing the output pole 21 into the accommodating cavity 1301 is formed between the first flange structure 1211 and the insulating cover 130.

[0096] It can be understood that a gap can be formed between the first flange structure 1211 and the insulating cover 130 for the output pole 21 to pass through, and the gap is the first wiring port 1302; alternatively, a slot structure can be opened in the insulating cover 130 toward the first flange structure 1211, so that the first flange structure 1211 is enclosed in the slot structure to form the first wiring port 1302.

[0097] It can be understood that the aforementioned direction toward the battery module 20 may be a direction perpendicular to the length direction X of the first beam 110 .

[0098] Since the first flange structure 1211 is formed to extend in the direction toward the battery module 20 , the first flange structure 1211 is oriented toward the accommodating space 101 , and the output pole 21 can pass through the first wiring port 1302 from the accommodating space 101 and enter the accommodating cavity 1301 for connection with the external electrical connection structure 22 .

[0099] With this arrangement, a first wiring port 1302 is formed between the first flange structure 1211 and the insulation cover 130 , and the output pole 21 can be connected to the accommodating cavity 1301 through the first wiring port 1302 ; moreover, the first flange structure 1211 can improve the insulation protection effect of the output pole 21 .

[0100] Referring to FIG. 4 to FIG. 6 , in some embodiments, the first flange structure 1211 extends out of the avoidance groove 111 , and the first flange structure 1211 is located between the first beam 110 and the output pole 21 .

[0101] It can be understood that the first flange structure 1211 is formed on the main body 121, and the first flange structure 1211 extends out of the avoidance groove 111. Then, the first flange structure 1211 located outside the avoidance groove 111 and the main body 121 located inside the avoidance groove 111 can block the part of the first beam 110 located at the notch of the avoidance groove 111 to achieve insulation protection.

[0102] At the same time, the first flange structure 1211 is also located between the first beam body 110 and the output pole 21. Furthermore, the first flange structure 1211 can separate the output pole 21 and the part of the first beam body 110 located at the slot of the avoidance groove 111 at the first wiring port 1302; thus, the first flange structure 1211 can increase the creepage distance between the first beam body 110 and the output pole 21 to further improve the insulation protection effect of the first beam body 110.

[0103] Referring to FIG. 3 to FIG. 6 , in some embodiments, the box body 10 further includes a partition plate 13 , and the partition plate 13 extends between the output pole 21 and the first flange structure 1211 .

[0104] The partition plate 13 is insulating and is used to be disposed in the accommodating space 101 . The partition plate 13 is also a support structure for integrating and fixing internal structures (such as guide plates, sampling harnesses, etc.).

[0105] In this way, by extending the insulating partition plate 13 between the output pole 21 and the first beam body 110, so that the partition plate 13 and the first flange structure 1211 form an overlapping part between the output pole 21 and the first beam body 110, the creepage distance between the output pole 21 and the first beam body 110 can be effectively increased, and the insulation protection effect between the output pole 21 and the first beam body 110 can be further improved.

[0106] 4 to 7 , in some embodiments, the main body 121 extends along the length direction X of the first beam 110 to form a second flange structure 1212 . The second flange structure 1212 is disposed on the outer surface of the first beam 110 .

[0107] Optionally, the main body 121 may form a second flange structure 1212 on either side of the first beam 110 in the length direction X, or the main body 121 may form a second flange structure 1212 on both opposite sides of the first beam 110 in the length direction X.

[0108] The second flange structure 1212 is provided on the outer surface of the first beam body 110. It can be understood that the second flange structure 1212 can abut against the outer surface of the first beam body 110, or be fixed to the outer surface of the first beam body 110 by bonding or fastener connection; or, the second flange structure 1212 can form a gap between the outer surface of the first beam body 110.

[0109] In this configuration, by forming the second flange structure 1212 in the length direction X of the first beam body 110 , the second flange structure 1212 can increase the creepage distance between the output pole 21 and the first beam body 110 in the length direction X of the first beam body 110 .

[0110] Referring to FIG. 4 to FIG. 7 , in some embodiments, the second flange structure 1212 is connected to the first flange structure 1211 and the fixing portion 122 , respectively.

[0111] It is understood that the second flange structure 1212 can be connected to the first flange structure 1211 by, for example, bonding, fastener connection, splicing, etc., or the second flange structure 1212 and the first flange structure 1211 can be integrally formed by injection molding or other methods. Similarly, the second flange structure 1212 can be connected to the fixing portion 122 by bonding, fastener connection, splicing, etc., or can be integrally formed by injection molding or other methods.

[0112] Among them, the second flange structure 1212 is formed on opposite sides of the main body 121 along the length direction X of the first beam body 110, the first flange structure 1211 is formed on the side of the main body 121 facing the battery module 20, and the second flange structure 1212 and the fixed part 122 are connected. Therefore, the first flange structure 1211, the second flange structure 1212 and the fixed part 122 can jointly enclose the part of the first beam body 110 located at the slot of the avoidance groove 111, so that the inside and outside of the avoidance groove 111 are separated, further reducing the probability of metal chips in the avoidance groove 111 falling out.

[0113] In this way, the second flange structure 1212 is connected to the first flange structure 1211 and the fixing part 122, so that the output pole 21 can increase the creepage distance between it and the first beam body 110 in the length direction X of the first beam body 110, or in the direction toward the battery module, and the insulation protection effect is better; at the same time, the first flange structure 1211, the second flange structure 1212 and the fixing part 122 can be surrounded by the notch of the avoidance groove 111 to achieve sealing of the avoidance groove 111, which can reduce the probability of metal chips inside the first beam body 110 falling out of the avoidance groove 111.

[0114] Referring to FIG. 4 , FIG. 5 and FIG. 7 , in some embodiments, a surface of the second flange structure 1212 facing the insulation cover 130 is provided with an undulating structure 12121 .

[0115] The undulating structure 12121 is formed on the side of the second flange structure 1212 facing the insulating cover 130. The undulating structure 12121 is a structure that fluctuates up and down on the surface of the second flange structure 1212. As a result, due to the characteristics of creepage current, the path of creepage current through the surface of the undulating structure 12121 is longer, thereby increasing the creepage distance from the output pole 21 within the accommodating cavity 1301 to the first beam 110.

[0116] For example, the undulating structure 12121 can be formed by the inward depression of the surface of the second flange structure 1212, that is, the undulating structure 12121 is a groove structure formed by the depression of the surface of the second flange structure 1212; the undulating structure 12121 can be formed by the outward protrusion of the surface of the second flange structure 1212, that is, the undulating structure 12121 is a convex strip structure formed by the protrusion of the surface of the second flange structure 1212.

[0117] Among them, the undulating structure 12121 can be arranged on the surface of the second flange structure 1212 along a direction perpendicular to the length direction X of the first beam body 110. Optionally, the undulating structure 12121 penetrates the second flange structure 1212 in a direction perpendicular to the length direction X of the first beam body 110; taking the undulating structure 12121 as an undulating groove as an example, the opposite ends of the undulating groove can penetrate the second flange structure 1212 to the outside in a direction perpendicular to the length direction X of the first beam body 110. Therefore, when creepage is generated on the second flange structure 1212 and extends toward the length direction X of the first beam body 110, the undulating groove can effectively increase the creepage distance.

[0118] It should be understood that the number of the undulating structures 12121 can be one or any number of more than one.

[0119] With this arrangement, creepage occurs along the surface of the insulator, forming an undulating structure 12121 on the second flange structure 1212 , which can effectively increase the creepage distance from the output pole 21 to the first beam 110 , further improving the protection effect of the output pole base 120 .

[0120] Please refer to FIG. 4 , FIG. 5 and FIG. 7 . In some embodiments, a first limiting portion 131 is formed on the insulating cover 130 . The first limiting portion 131 is plugged into and matched with the undulating structure 12121 .

[0121] It can be understood that the first limiting portion 131 is plugged into and matched with the undulating structure 12121; in some embodiments, the undulating structure 12121 can be an undulating groove, and thus, the first limiting portion 131 can be a plug-in block formed on the insulating cover 130, and the plug-in block is plugged into the undulating groove, so that the plug-in block can only move along the undulating groove, and the undulating groove can limit the movement of the plug-in block in other directions.

[0122] In other embodiments, the undulating structure 12121 may be an undulating ridge, whereby the first limiting portion 131 may be an insert slot formed on the insulating cover 130, and the undulating ridge may form an insert fit with the insert slot, so that the insulating cover 130 is limited to move only along the length direction of the undulating ridge.

[0123] With this arrangement, the insulating cover 130 is plugged into and matched with the undulating structure 12121 via the first limiting portion 131 , and the undulating structure 12121 can limit the movement of the first limiting portion 131 , thereby limiting the movement of the insulating cover 130 .

[0124] Please refer to Figures 4, 5 and 7. In some embodiments, the main body 121 is recessed in the length direction X of the first beam 110 to form a snap-fit ​​groove 1213, and a snap-fit ​​portion 132 is formed on the insulation cover 130, which is inserted into the snap-fit ​​groove 1213.

[0125] It is understood that the snap-fit ​​groove 1213 is a groove structure formed on the main body 121. The snap-fit ​​groove 1213 can be, but is not limited to, a strip-shaped groove, a rectangular groove, a circular groove, etc.; for example, the snap-fit ​​groove 1213 can be a strip-shaped groove, with the length of the strip extending toward the battery module 20. The snap-fit ​​groove 1213 can be located anywhere on the outer surface of the main body 121 to facilitate insertion of the snap-fit ​​portion 132 of the insulating cover 130. Optionally, the number of snap-fit ​​grooves 1213 can be one or more.

[0126] The clamping portion 132 is formed on the insulating cover 130. Optionally, the clamping portion 132 can be, but is not limited to, a block structure, a sheet structure, a rod structure, etc. formed on the insulating cover 130. The number of the clamping portions 132 can be one or more. The clamping portion 132 is used to be inserted into the clamping groove 1213 and form a plug-in fit. The inner wall of the clamping groove 1213 can limit the clamping portion 132 to restrict its movement.

[0127] In this arrangement, the snap-in groove 1213 on the main body 121 is used to plug and connect the snap-in portion 132 of the insulating cover 130, so that the snap-in groove 1213 limits the movement of the snap-in portion 132, that is, limits the movement of the insulating cover 130 relative to the main body 121, and the insulating cover 130 can be maintained in a state where it is covered on the main body 121.

[0128] For example, in some embodiments, the snap-fit ​​groove 1213 is a strip groove opened on the main body 121, and the snap-fit ​​portion 132 is a snap-fit ​​protrusion formed at one end of the insulation cover 130 facing the main body 121. In the process of covering the insulation cover 130 on the main body 121, the snap-fit ​​protrusion is inserted into the strip groove, so that the insulation cover 130 can remain in a state of covering the main body 121; when the insulation cover 130 needs to be removed, the insulation cover 130 can be squeezed along the length direction X of the first beam 110 so that the snap-fit ​​protrusion on the insulation cover 130 can be moved out of the strip groove.

[0129] Please refer to Figures 4, 5 and 7. In some embodiments, a limiting groove 1214 is opened on the main body 121, and a second limiting portion 133 is formed on the insulating cover 130. The second limiting portion 133 is inserted into the limiting groove 1214. The limiting groove 1214 is used to limit the movement of the second limiting portion 133 in a direction perpendicular to the length direction X of the first beam body 110.

[0130] The limiting groove 1214 is a groove structure opened on the main body 121. The limiting groove 1214 can be, but is not limited to, a groove structure such as a strip groove, a rectangular groove, or a circular groove. The number of the limiting grooves 1214 can be one or more.

[0131] The second limiting portion 133 is formed on the insulating cover 130. Optionally, the second limiting portion 133 can be, but is not limited to, a block structure, a sheet structure, a rod structure, etc. formed on the insulating cover 130. The number of the second limiting portions 133 can be one or more. The second limiting portion 133 is used to be inserted into the limiting groove 1214 and form a plug-in fit. The inner wall of the limiting groove 1214 can limit the second limiting portion 133 to limit its movement in the direction perpendicular to the length direction X of the first beam body 110.

[0132] For example, in some embodiments, the main body 121 is formed with two protrusions at intervals along a direction perpendicular to the length direction X of the first beam body 110, and a limiting groove 1214 is formed between the two protrusions. When the insulating cover 130 is covered on the main body 121, the second limiting portion 133 can be inserted into the limiting groove 1214, and the opposite ends of the second limiting portion 133 respectively abut against the wall surfaces of the two protrusions, so that the movement of the insulating cover 130 in the direction perpendicular to the length direction X of the first beam body 110 is limited.

[0133] Please refer to Figures 4 to 7. In some embodiments, the main body 121 includes a base portion 121a, a first enclosure portion 121b arranged on the base portion 121a, and two second enclosure portions 121c arranged opposite to each other on the base portion 121a, and the two second enclosure portions 121c are respectively connected to the first enclosure portion 121b; the insulating cover 130 and the base portion 121a, the first enclosure portion 121b and the second enclosure portion 121c are enclosed to form a accommodating cavity 1301.

[0134] It can be understood that the base 121a, the first enclosure part 121b and the second enclosure part 121c can all be sheet structures or block structures, and the base 121a and the first enclosure part 121b and the two second enclosure parts 121c arranged on the base 121a can be enclosed to form an inwardly concave groove structure. Therefore, when the insulating cover 130 is mounted on the main body 121, the insulating cover 130 can cover the enclosed groove structure and form a accommodating cavity 1301.

[0135] Furthermore, when at least a portion of the main body 121 is accommodated within the avoidance groove 111, the first enclosure portion 121b of the main body 121 faces one side of the battery module 20, and the second enclosure portions 121c are located on opposite sides of the first enclosure portion 121b in the longitudinal direction X of the first beam 110. A first flange structure 1211 is formed on the first enclosure portion 121b, and two second enclosure portions 121c extend from opposite sides thereof to form second enclosure portions 121c. A snap-fit ​​groove 1213 is formed on opposite side walls of the two second enclosure portions 121c, and a retaining groove 1214 is formed on the sides of the two second enclosure portions 121c facing away from the base portion 121a. The fixing portion 122 can be connected to the outer surface of the base portion 121a and extend toward the second enclosure portions 121c on both sides to connect to the second flange structure 1212.

[0136] Referring to FIG. 4 to FIG. 7 , in some embodiments, the output pole base 120 further includes a connecting portion 123 . The connecting portion 123 is disposed on the main body 121 and located within the accommodating cavity 1301 . The output pole 21 is connected to the connecting portion 123 .

[0137] The connecting portion 123 is a component used to fix the output pole 21 and to connect the output pole 21 and the external electrical connection structure 22 .

[0138] Optionally, the connecting portion 123 may be a connecting portion 123 having a threaded hole, whereby the output pole 21 can be fixed to the connecting portion 123 by means of bolts or screws, and a fixed connection is formed; or, the connecting portion 123 may be a clamping component with a clamping function, by inserting the output pole 21 into the clamping component and operating the clamping component to clamp the output pole 21 and form a connection.

[0139] In some embodiments, the connecting portion 123 can be a gasket with a threaded hole, and a connecting groove is provided on the base portion 121a of the main body 121, and the gasket is assembled in the connecting groove. Thus, the output pole 21 and the peripheral electrical connection structure 22 can be stacked on the gasket and tightened into the threaded hole of the gasket using fasteners such as bolts or screws, so that the output pole 21 and the peripheral electrical connection structure 22 are fixed on the gasket, and the connecting groove can avoid fasteners such as bolts or screws.

[0140] With such a configuration, the output pole 21 can be connected to the connecting portion 123 in the accommodating cavity 1301 , thereby facilitating the connection operation of the output pole 21 in the accommodating cavity 1301 .

[0141] For example, in some specific embodiments, the output pole base 120 includes a main body 121 and a fixing portion 122. The main body 121 includes a base portion 121a, a first enclosure portion 121b and two second enclosure portions 121c provided on the base portion 121a. The first enclosure portion 121b extends toward the battery module 20 to form a first flange structure 1211. The two second enclosure portions 121c are respectively formed with a second flange structure 1212. The second flange structure 1212 is connected to the first flange structure 1211 to form a whole. The base portion 121a A connecting groove is formed on it, and a gasket with a threaded hole is assembled in the connecting groove; the fixing part 122 includes a first connecting structure 1221, a second connecting structure 1222 and a third connecting structure 1223 that are connected to each other, and the first connecting structure 1221 and the second connecting structure 1222 are both provided with mounting holes, wherein the third connecting structure 1223 is connected to the outer surface of the base 121a, and the first connecting structure 1221 and the second connecting structure 1222 are respectively connected to the outer surfaces of the two second enclosure parts 121c and extend to connect to the second flange structure 1212. Therefore, when assembling the output pole base 120, part of the main body 121 is accommodated in the avoidance groove 111 of the first beam body 110, so that the fixing part 122 is in contact with the side surface of the first beam body 110 facing away from the battery module 20 and is fixed to the first beam body 110 through the mounting hole by fasteners; the fixing part 122, the first flange structure 1211 and the second flange structure 1212 can all be set against the surface of the first beam body 110, and can jointly surround the notch of the avoidance groove 111. The insulating cover 130 is covered on the main body 121, so that the insulating cover 130 and the base 121a, the first enclosure 121b and the second enclosure 121c together enclose a accommodating cavity 1301; the output pole 21 can be passed through the first flange structure 1211 and the insulating cover 130 into the accommodating cavity 1301, and the external electrical connection structure can be passed through the insulating cover 130 and the side of the base 121a facing away from the first enclosure 121b into the accommodating cavity 1301, so that the output pole 21 and the external electrical connection structure 22 can be fastened to the gasket by bolts to achieve electrical connection.
