[0053] The connector 6 is disposed in the connecting portion 2, and the portion of the conductive bar of the battery that needs to be fixed is placed in the fixing portion 1. The conductive bar can be fixed by passing a fastener in the form of a screw through the conductive bar and connecting the conductive bar to the connector 6. Preferably, the side wall of the fixing portion 1 is provided with an escape notch, and the portion of the conductive bar that needs to be fixed enters the fixing portion 1 through the escape notch, and the escape notch can avoid the conductive bar so that the conductive bar can extend outward.

[0054] Further, the fixing portion 1 has a slot structure, the interior of the connecting portion 2 is hollow to form a mounting slot 201, the mounting slot 201 is communicated with the internal space of the fixing portion 1, and the connecting member 6 is arranged in the mounting slot 201. The inner wall of the mounting slot 201 is provided with a first clamping portion 202, and the outer wall of the connecting member 6 is provided with a second clamping portion 601, and the second clamping portion 601 can be adapted to be clamped with the first clamping portion 202 to limit the connecting member 6 in the mounting slot 201.

[0055] Preferably, the first clamping portion 202 is specifically an annular protrusion arranged along the circumference of the inner wall surface of the installation groove 201. More preferably, the number of the first clamping portions 202 is two or more, and all the first clamping portions 202 are arranged at intervals along the depth of the installation groove 201. The second clamping portion 601 is specifically an annular groove extending along the circumference of the outer wall surface of the connecting member 6, and the shape of the annular groove is adapted to the shape of the annular protrusion, so that the connecting member 6 can be limited in the installation groove 201. It should be noted that the number of the second clamping portions 601 is the same as the number of the first clamping portions 202, and they are arranged one by one.

[0056] Further, the output pole base also includes a locking member 4, which is arranged on the outer side wall of the connecting part 2, and is used to engage with the connecting cavity 301, so that the output pole base can be fixed and locked on the end plate 3. The locking member 4 includes a support part 401 and a locking part 402, wherein the support part 401 has a rod structure or a plate structure, and a wall surface of the connecting part 2 that is not in contact with the fixing part 1 is defined as a bottom wall surface, one end of the support part 401 is connected to a side edge of the bottom wall surface of the connecting part 2, and the other end of the support part 401 is a free end, which extends toward the lower surface of the fixing part 1 but does not contact, and a gap is formed between the support part 401 and the side wall of the connecting part 2, so that when an external force acts on the free end, the free end can approach the connecting part 2, and the support part 401 itself has elasticity, and after the external force disappears, the support part 401 can return to its original position by its own elastic force. Preferably, the support part 401 and the connecting part 2 have an integral structure. The locking portion 402 is disposed on a surface of the free end facing away from the connecting portion 2 . Preferably, the locking portion 402 and the free end have an integral structure. The locking portion 402 protrudes relative to the free end to form a convex portion 4021 , which can be snap-fitted with the connecting cavity 301 .

[0057] The outer wall surface of the free end is also formed with an unlocking inclined surface 4022, and the unlocking inclined surface 4022 and the convex portion 4021 are located on the same wall surface of the free end, and the unlocking inclined surface 4022 and the convex portion 4021 are arranged from top to bottom, and the two are naturally transitionally connected. Fig.14 From the perspective shown, the cross-sectional area of ​​the unlocking slope 4022 gradually increases from top to bottom.

[0058] The inner wall of the connecting cavity 301 is provided with a card slot. When the output pole base is assembled to the end plate 3, the connecting part 2 is aligned with the connecting cavity 301, and the connecting part 2 is inserted into the connecting cavity 301. The inner wall of the connecting cavity 301 can gradually squeeze the unlocking inclined surface 4022. At this time, the free end and the unlocking inclined surface 4022 and the convex part 4021 on the free end gradually approach the connecting part 2. After the connecting part 2 is inserted into place, the convex part 4021 is directly opposite to the card slot on the inner wall of the connecting cavity 301. The convex part 4021 is no longer affected by external force and returns to its original position. At this time, the convex part 4021 is just snapped into the card slot, thereby realizing the snap connection between the connecting part 2 and the connecting cavity 301.

[0059] When disassembling the output pole base, force is applied to the unlocking slope 4022 again, and the unlocking slope 4022 can continue to be driven by the force to move toward the connecting part 2. At this time, the free end and the unlocking slope 4022 and the protrusion 4021 on the free end simultaneously approach the connecting part 2 until the protrusion 4021 is released from the slot, and the output pole base can be pulled outward to separate the output pole base from the end plate 3.

[0060] Preferably, the number of locking members 4 is at least two, the connecting part 2 has four side walls, and the two locking members 4 are arranged on two side walls of the connecting part 2 facing each other. The shape of the connecting cavity 301 is adapted to the shape of the connecting part 2. The connecting cavity 301 includes a bottom wall and four side walls connected end to end. The number of slots on the inner wall of the connecting cavity 301 is the same as the number of locking members 4 and is arranged one by one. Of course, the number of locking members 4 and the number of slots can also be four. A locking member 4 is arranged on the outer wall surface of each side wall of the connecting part 2, and a slot is arranged on the inner wall surface of each side wall of the connecting cavity 301, so as to ensure the clamping strength and stability between the output pole base and the end plate 3.

[0061] Example 2, see Figures 6 to 13 As shown, the second embodiment of the present application provides another output pole base, which includes a fixing part 1, a connecting part 2 and a connecting member 6, wherein the specific structure, positional relationship, and connection method of the fixing part 1, the connecting part 2, and the connecting member 6 are the same as those described in the first embodiment above regarding the fixing part 1, the connecting part 2, and the connecting member 6, and the same contents will not be repeated here, which can be fully understood by those skilled in the art.

[0062] Furthermore, the output pole base also includes a locking member 4, which is arranged at the bottom of the fixing portion 1, and is used to engage with the connecting cavity 301 to fix the output pole base on the end plate 3. Specifically, an extension portion 101 is arranged at the bottom of the fixing portion 1, and the extension portion 101 has a flat plate structure. The extension portion 101 is arranged at a distance from the connecting portion 2, and a hollow portion is arranged at the center of the flat plate structure of the extension portion 101. The locking member 4 is arranged in the hollow portion. The locking member 4 specifically includes a supporting portion 401 and a locking portion 402, wherein the supporting portion 401 is arranged in the hollow portion, and the locking member 4 includes a supporting portion 401 and a locking portion 402. Figure 6 In the state shown, one end of the support portion 401 is connected to the extension portion 101. Specifically, the bottom end of the support portion 401 is fixedly connected to the bottom edge of the hollow portion, and the other end of the support portion 401 is a free end, which extends toward the top edge of the hollow portion. Preferably, the support portion 401 and the extension portion 101 have an integral structure. The locking portion 402 is arranged at the free end, and the locking portion 402 is arranged on a side surface of the free end away from the connecting portion 2. The locking portion 402 is raised relative to the free end to form a convex portion 4021 for clamping with the connecting cavity 301. In addition, since one end of the support portion 401 is fixed and the other end is in a free state, combined with the support portion 401 being made of a plastic material having insulation and a certain elasticity, when an external force pushes the convex portion 4021, the free end of the support portion 401 can be tilted toward the connecting portion 2.

[0063] The free end is also provided with an unlocking inclined surface 4022, which is provided at the top of the support portion 401 and is located above the convex portion 4021. Figure 6 In the perspective shown, the cross-sectional area of ​​the unlocking slope 4022 gradually increases from top to bottom. The inner wall of the connection cavity 301 is provided with a card slot. When the output pole base is assembled to the end plate 3, the connection part 2 is aligned with the connection cavity 301 and the connection part 2 is inserted into the connection cavity 301. The inner wall surface of the connection cavity 301 can gradually squeeze the unlocking slope 4022. At this time, the free end and the unlocking slope 4022 and the convex part 4021 on the free end gradually approach the connection part 2. After the connection part 2 is inserted in place, the convex part 4021 is directly opposite to the card slot on the inner wall of the connection cavity 301. The convex part 4021 is no longer affected by external force and returns to its original position. At this time, the convex part 4021 is just inserted into the card slot, thereby realizing the card connection between the connection part 2 and the connection cavity 301.

[0064] Preferably, the number of the locking members 4 is at least two, the number of the extensions 101 is the same as the number of the locking members 4 and is arranged one-to-one, and accordingly, the slots in the connection cavity 301 are also arranged corresponding to the number of the locking members 4. In this embodiment, the number of the locking members 4 and the number of the extensions 101 are preferably two, one of the extensions 101 is arranged on the bottom wall surface of the fixing portion 1 close to one end edge of the bottom wall surface, and the other extension 101 is arranged at the other end edge of the bottom wall surface of the fixing portion 1, and the two extensions 101 are distributed on both sides of the connection portion 2, so that the fixing portion 1 is clamped with the connection cavity 301 through two clamping points, ensuring the clamping strength between the output pole base and the connection cavity 301, thereby ensuring the stability of the output pole base on the end plate 3.

[0065] To sum up, the output pole base provided in the present application can be stably arranged on the end plate 3, and the connecting part 2 is connected to the end plate 3 by being embedded in the cavity of the end plate 3, so that the output pole base will not occupy excessive installation space, thereby improving the utilization rate of the internal space of the battery, and does not require too much special processing on the end plate 3, which can effectively avoid weakening the structural strength of the end plate 3.

One of the plurality of cavities is a connecting cavity 301, and preferably, the connecting cavity 301 is located in the middle of a plurality of cavities arranged in sequence.

[0068] First limit slots 302 are symmetrically arranged on the two side walls of the connecting cavity 301 facing each other. The two first limit slots 302 are distributed along the length direction of the end plate 3. After the connecting part 2 of the above-mentioned embodiment 1 is inserted into the connecting cavity 301, a locking member 4 on the connecting part 2 is mutually engaged with a first limit slot 302, and another locking member 4 on the connecting part 2 is mutually engaged with another first limit slot 302, thereby fixing the output pole base on the end plate 3.

[0069] Furthermore, the battery further comprises an unlocking member 5, the unlocking member 5 comprises a main body 502 and an abutment 501, wherein the main body 502 has a U-shaped structure, and two ends of the U-shaped structure of the main body 502 are the abutment 501. Fig.14 In the shown state, the cross-sectional area of ​​the abutment 501 gradually decreases from top to bottom, and at the same time, the distance between the abutment 501 at both ends of the main body 502 gradually increases from top to bottom, so that the shape of the abutment 501 can adapt to the shape of the unlocking slope 4022.

[0070] The bottom of the fixing part 1 is provided with an unlocking hole 102 which passes through the inner and outer surfaces of the fixing part 1. The number of the unlocking holes 102 can be specifically two. The two unlocking holes 102 are distributed on both sides of the connecting member 6. The distance between the two unlocking holes 102 is adapted to the distance between the two abutting joints 501, so that one of the abutting joints 501 can be aligned with one of the unlocking holes 102, and the other abutting joint 501 can be aligned with the other unlocking hole 102, so that the abutting joint 501 can pass through the bottom of the fixing part 1 after passing through the unlocking hole 102, so that the abutting joint 501 can abut and squeeze the unlocking inclined surface 4022 of the locking member 4 after passing through the unlocking hole 102. As the unlocking member 5 continues to be inserted downward, the abutting joint 501 can squeeze the free end of the locking member 4 to approach the connecting part 2, and the locking parts 402 on both sides of the connecting part 2 are simultaneously disengaged from the first limiting slot 302, so that the connecting part 2 can be pulled out of the connecting cavity 301, and the output pole base is separated from the end plate 3.

[0071] Example 4, see Fig.12 and Fig.15, Embodiment 4 of the present application provides another battery, including the output pole base described in Embodiment 2 above. The battery includes: an end plate 3, the end plate 3 is made of a profile, and a plurality of cavities are formed inside, the plurality of cavities are spaced apart along the length direction of the end plate 3, the depth of each cavity extends along the height direction of the end plate 3, one of the plurality of cavities is a connecting cavity 301, and preferably, the connecting cavity 301 is located in the middle of a plurality of cavities arranged in sequence.

[0072] The multiple cavities also include a fixed cavity 304, which is arranged adjacent to the connecting cavity 301. Preferably, there are two fixed cavities 304, and along the length direction of the end plate 3, the cavities on both sides of the connecting cavity 301 are fixed cavities 304. The inner wall surface of the side wall of the fixed cavity 304 facing the connecting cavity 301 and relatively far away from the connecting cavity 301 is provided with a second limiting card groove 303. After the connecting part 2 in the above-mentioned embodiment 2 is plugged into the connecting cavity 301, a locking member 4 at the bottom of the fixing part 1 is mutually engaged with the second limiting card groove 303 in the fixing cavity 304 on one side of the connecting cavity 301, and another locking member 4 at the bottom of the fixing part 1 is mutually engaged with the second limiting card groove 303 in the fixing cavity 304 on the other side of the connecting cavity 301, thereby fixing the output pole base on the end plate 3.

[0073] Furthermore, the output pole base further comprises an unlocking member 5, which comprises a main body 502 and an abutment head 501, wherein the main body 502 has a U-shaped structure, and the two ends of the U-shaped structure of the main body 502 are the abutment heads 501. Fig.15 In the shown state, the cross-sectional area of ​​the abutment 501 gradually decreases from top to bottom, and at the same time, the distance between the abutment 501 at both ends of the main body 502 gradually increases from top to bottom, so that the shape of the abutment 501 can be adapted to the shape of the unlocking slope 4022.

[0074] The upper end port of the second limiting slot 303 extends to the upper end surface of the side wall of the fixing cavity 304. The second limiting slot 303 is L-shaped as a whole.
