Embodiment 1
[0038] An embodiment of the present application provides a lithium battery pole module.
[0039] like figure 1 and figure 2 As shown, a lithium battery pole module includes a pole 1 , a wrapping ring 2 and a sealing ring 5 .
[0040] The pole 1 includes a cylinder 11 and lugs 12, and the lugs 12 are fixed on the circumferential side of the cylinder 11. In this embodiment, the cylinder 11 is cylindrical, and two lugs 12 are provided. The cylinders 11 are uniformly distributed in the circumferential direction, and the lugs 12 and the cylinders 11 are integrally arranged. In other embodiments, the number of lugs 12 may also be one or other numbers, and the cross-section of the cylinder 11 may also be rectangular or other polygonal.
[0041] The wrapping ring 2 surrounds the outer periphery of the pole 1, and the wrapping ring 2 is fixed with a ring-shaped support edge 3, the ring-shaped support edge 3 abuts against the edge of the end face of the pole 1, and the ring-shaped s...
Embodiment 2
[0053] An embodiment of the present application provides a lithium battery pole module.
[0054] The lithium battery pole module of the present application is the same as that of the first embodiment.
[0055] The application also discloses a lithium battery top cover.
[0056] A top cover for a lithium battery. The difference between this embodiment and the first embodiment lies in that the connection mode between the rivet 8 and the lower plastic plate 7 is different.
[0057] like Figure 9 and Figure 10 As shown, the rivet 8 is pre-fixed on the lower plastic plate 7, the cap of the rivet 8 is fixed on the lower plastic plate 7, the cap of the rivet 8 is injection molded on the lower plastic plate 7, and the shank of the rivet 8 passes through the cover plate 6 , ring support edge 3 and pole 1. The lower plastic plate 7 is provided with an embedding groove 93 for accommodating the embedding groove 93 sleeved on the limiting ring 92 of the sealing sleeve 9 .
