[0027] Batteries are devices that convert chemical energy into electrical energy and are used very widely in daily life. As the battery industry develops, companies are increasingly demanding higher production efficiency and yield for batteries. Conventional batteries consist of battery cells and a case. Generally, the positive electrode of the battery cell is drawn from the case by electrode poles. Specifically, the electrode poles and the case are isolated by an insulating material, and a fixed connection is made between the electrode poles, the case, and the insulating material. However, the inventors have found that when fixing the electrode poles, the case, and the insulating material, relative rotation is likely to occur between the insulating material and the battery case, making the subsequent fixing unstable and reducing the battery yield.

[0028] In view of this, the present invention provides a battery comprising a battery cell, a case, a pole base, and a first insulating member, wherein the case has a housing cavity in which the battery cell is arranged, the pole base comprises a body and poles, pole hole is provided in the side wall of the case, the first insulating member is arranged between the case and the body, the first insulating member is provided with a first positioning hole opposite to the pole hole, the pole passes through the first positioning hole and the pole hole in sequence, the pole is connected to the electrode tab of the battery cell, the first insulating member is further provided with a third position limiting portion, and a fourth position limiting portion is provided on the outer wall of the case, the third position limiting portion is locked and connected to the fourth position limiting portion. The battery provided by the present invention is configured such that a third position limiting portion is provided on the first insulating member, and a fourth position limiting portion is provided on the outer wall of the case that matches the third position limiting portion. As a result, when assembling the first insulating member and the battery case, the third position limiting portion on the first insulating member can be locked and connected to the fourth position limiting portion on the case. Consequently, rotation of the first insulating member relative to the battery case can be prevented, thereby improving the production yield and efficiency of the battery.

[0029] Figure 1 is a schematic diagram of the overall structure of the battery provided according to an embodiment of the present invention, Figure 2 is an exploded view of the battery provided according to an embodiment of the present invention, Figure 3 is a side view of the battery provided according to an embodiment of the present invention, Figure 4 is a cross-sectional view of AA in Figure 3, Figure 5 is an enlarged view of A in Figure 4, and Figure 6 is a schematic assembly diagram of Figure 5. Please refer to Figures 1 to 6. An embodiment of the present invention provides a battery 100 comprising a battery cell 110, a case 120, a pole base 130, and a first insulating member 140, wherein the case 120 has a housing cavity in which the battery cell 110 is arranged, the pole base 130 comprises a body 131 and poles 132, pole holes 121 are provided in the side wall of the case 120, and the first insulating member 140 is arranged between the case 120 and the body 131, and the first The insulating member 140 is provided with a first positioning hole 141 facing the pole post hole 121, the pole post 132 sequentially passes through the first positioning hole 141 and the pole post hole 121, and the pole post 132 is connected to the electrode tab of the battery cell 110, the first insulating member 140 is further provided with a third position limiting portion 143, and a fourth position limiting portion 122 is provided on the outer wall of the case 120, and the third position limiting portion 143 is locked and connected to the fourth position limiting portion 122.

[0030] The battery cell 110 comprises a negative electrode made of a negative electrode material, a positive electrode made of a positive electrode material, and a separator separating the positive electrode and the negative electrode. The arrangement of the battery cell 110 may be a wound type, a stacked type, or the like, and this embodiment is not particularly limited to this.

[0031] The case 120 serves to protect the battery cell 110, and the case 120 may be formed by joining two parts together to facilitate installation. Stainless steel, which is robust and corrosion-resistant, can be selected as the material for the case 120, although other materials may be used, and this embodiment is not particularly limited to these materials.

[0032] The pole base 130 primarily serves to guide the electricity from the positive electrode of the battery cell 110 to the outside of the battery case 120 for easier use. The pole base 130 can be made of a material with good conductivity, such as copper or aluminum, and is not particularly limited in this specification.

[0033] The first insulating member 140 can be made from a material with good insulating properties such as rubber or resin, and the first insulating member 140 mainly plays the role of isolating the pole base 130 and the case 120, which is generally used as the negative electrode of the battery 100. In other words, it should be understood that the first insulating member 140 is used to isolate the positive and negative electrodes of the battery 100 in order to ensure that the battery 100 operates normally.

[0034] One assembly method for the pole post base 130 is shown in Figures 4 to 6, in which the pole post base 130 comprises pole posts 132, the first insulating member 140 has a first positioning hole 141, and the case 120 has a pole post hole 121. During assembly, one end of the pole post 132 away from the body 131 can sequentially pass through the first positioning hole 141 and the pole post hole 121 before being electrically connected to the positive electrode of the battery cell 110, thereby allowing the electricity from the positive electrode of the battery cell 110 to be guided out of the case 120 via the pole post 132.

[0035] It should be understood that the first insulating member 140 should isolate the pole base 130 from the case 120. Specifically, as shown in Figures 5 and 6, during implementation, the flange can be extended around the edge of the first positioning hole 141 toward one side of the case 120. When assembling the first insulating member 140 from the case 120, the flange can be fitted into the pole hole 121 on the case 120, and the pole 132 can be passed through the first positioning hole 141. In this way, the object that contacts the outer wall of the pole 132 is not the inner wall of the pole hole 121 (i.e., the inner wall of the case 120), but the inner wall of the first positioning hole 141 and the flange (i.e., the object that contacts is the first insulating member 140). This isolates the pole base 130 from the case 120 by the first insulating member 140, ensuring that the positive and negative electrodes of the battery 100 do not interfere with each other and that it operates normally.

[0036] In the battery 100 provided by an embodiment of the present invention, a third position limiting portion 143 is provided on the first insulating member 140, and a fourth position limiting portion 122 that matches the third position limiting portion 143 is provided on the outer wall of the case 120. As a result, when assembling the first insulating member 140 and the case 120 of the battery 100, the third position limiting portion 143 on the first insulating member 140 can be locked and connected to the fourth position limiting portion 122 on the case 120. Consequently, rotation of the first insulating member 140 relative to the case 120 of the battery 100 can be prevented, thereby improving the production yield and efficiency of the battery 100.

[0037] In the above embodiment, one of the third position limiting portion 143 and the fourth position limiting portion 122 can be a groove, and the other can be a protrusion fitted into the groove. Specifically, as shown in Figures 5 and 6, the third position limiting portion 143 is a protrusion provided on the first insulating member 140 that faces the case 120, and the fourth position limiting portion 122 is a groove provided on the case 120 that is away from the battery cell 110.

[0038] Alternatively, the third position limiting portion 143 is a groove provided in the first insulating member 140 that is closer to the case 120, and the fourth position limiting portion 122 is a projection provided in the case 120 that faces toward the first insulating member 140.

[0039] In the above embodiment, the main body 131 is provided with a first position limiting portion 133, and the first insulating member 140 is further provided with a second position limiting portion 142, and the first position limiting portion 133 is locked and connected to the second position limiting portion 142. By providing a first position limiting portion 133 on the main body 131 of the pole column base 130 and a second position limiting portion 142 on the first insulating member 140 that matches the first position limiting portion 133, when assembling the pole column base 130 and the first insulating member 140, the pole column 132 located on the main body 131 of the pole column base 130 passes through the first positioning hole 141 on the first insulating member 140, and at the same time, the first position limiting portion 133 located on the main body 131 of the pole column base 130 locks into place with the second position limiting portion 142 on the first insulating member 140. As a result, rotation of the pole column base 130 relative to the first insulating member 140 is prevented, improving the production yield and efficiency of the battery 100.

[0040] In actual implementation, one of the first position limiting portion 133 and the second position limiting portion 142 can be a groove, and the other can be a protrusion. Specifically, as shown in Figures 5 and 6, the first position limiting portion 133 is a protrusion provided on the main body 131 that faces the case 120, and the second position limiting portion 142 is a groove provided on the first insulating member 140 that is away from the case 120. Alternatively, the first position limiting portion 133 is a groove provided on the main body 131 that is close to the case 120, and the second position limiting portion 142 is a protrusion provided on the first insulating member 140 that faces the case 120.

[0041] In the above embodiment, the first position limiting portion 133 may be located on the side of the main body 131 facing the battery cell 110, and the second position limiting portion 142 is provided facing the main body 131.

[0042] In the above embodiment, there may be multiple first position limiting portions 133, and multiple first position limiting portions 133 are provided in parallel on the main body 131. Accordingly, the first insulating member also has multiple second position limiting portions 142, and when assembling the main body 131 of the pole column base 130 and the first insulating member 140, the multiple first position limiting portions 133 on the main body 131 are locked and connected simultaneously with the multiple second position limiting portions 142 on the first insulating member 140, thereby further preventing rotation of the pole column base 130 relative to the first insulating member 140, improving the rigidity and reliability of the assembly between the pole column base 130 and the first insulating member 140, and improving the production yield of the battery 100.

[0043] As shown in Figures 4 to 6, the above embodiment further includes a conductive connector 150, which is located inside the case 120 and connected to the electrode tab of the battery cell 110. Specifically, the conductive connector 150 may be connected between the positive electrode of the battery cell 110 and the electrode post 132 in order to transmit the electricity from the positive electrode of the battery cell 110 to the electrode post 132 and the electrode post 132 to draw the electricity out of the case 120. By arranging the conductive connector 150, the battery cell 110 and the electrode post 132 can be connected more firmly.

[0044] In the above embodiment, a gap may be placed between the fourth position limiting portion 122 and the conductive connector 150 to prevent electrical contact between the fourth position limiting portion 122 and the conductive connector 150.

[0045] In the above embodiment, the fourth position limiting portion 122 may be machined into a groove with its bottom protruding inward toward the inside of the case 120, as shown in Figures 5 and 6, or the fifth position limiting portion 162 may be provided on the side of the second insulating member 160 closer to the case 120, and the fourth position limiting portion 122 is locked and connected to the third position limiting portion 143 and the fifth position limiting portion 162 simultaneously. Of course, in order to achieve the locking connection with the fifth position limiting portion 162, other position limiting portions may be individually provided on the inner wall of the case 120. By providing the fifth position limiting portion 162 to be locked and connected to the inner wall of the case 120, rotation of the second insulating member 160 relative to the case 120 can be prevented, thereby improving the rigidity and reliability of the assembly between the second insulating member 160 and the case 120. The fifth position limiting portion 162 may be a through hole as shown in Figure 5, or of course, the fifth position limiting portion 162 may be a groove structure, and is not particularly limited in this specification.

[0046] In the above embodiment, a second insulating member 160 may be further provided, the second insulating member 160 being located inside the case 120, the second insulating member 160 isolating the case 120 from the conductive connector 150, and the second insulating member 160 and the conductive connector 150 are engaged with each other. The second insulating member 160 mainly serves to isolate the case 120 (the negative electrode of the battery 100) from the conductive connector 150 (the positive electrode of the battery 100), ensuring that the positive and negative electrodes of the battery 100 do not affect each other. Refer to Figure 6 for one assembly method of the conductive connector 150 and the second insulating member 160. The second insulating member 160 and the conductive connector 150 can be provided with a second positioning hole 161 and a third positioning hole 151, respectively, and the pole 132 on the pole base 130 can sequentially pass through the first positioning hole 141, the pole hole 121, the second positioning hole 161, and the third positioning hole 151.

[0047] In the above embodiment, a sixth position limiting portion 163 is provided on the side of the second insulating member 160 away from the case 120, and a seventh position limiting portion 152 is provided on the side of the conductive connector 150 closer to the second insulating member 160, and the sixth position limiting portion 163 may be locked and connected to the seventh position limiting portion 152. The locking connection between the sixth position limiting portion 163 and the seventh position limiting portion 152 prevents the conductive connector 150 from rotating relative to the second insulating member 160, thereby improving the rigidity and reliability of the assembly between the conductive connector 150 and the second insulating member 160. Specifically, the sixth position limiting portion 163 may be a projection facing the conductive connector 150 side, as shown in Figure 5, and the seventh position limiting portion 152 may be a groove facing the second insulating member 160 side.

[0048] In the above embodiment, the external shapes of the first position limiting portion 133, the second position limiting portion 142, the third position limiting portion 143, the fourth position limiting portion 122, the sixth position limiting portion 163, and the seventh position limiting portion 152 may be rectangular, circular, or triangular.

[0049] In the above embodiment, the diameters of the first position limiting portion 133, the second position limiting portion 142, the third position limiting portion 143, the fourth position limiting portion 122, the sixth position limiting portion 163, and the seventh position limiting portion 152 are all greater than 0.5 mm.

As a result, when assembling the first insulating member 140 and the case 120 of the battery 100, the third position limiting portion 143 on the first insulating member 140 can be locked and connected to the fourth position limiting portion 122 on the case 120. Consequently, rotation of the first insulating member 140 relative to the case 120 of the battery 100 can be prevented, thereby improving the production yield and efficiency of the battery 100.
