Problems solved by technology

[0002] At present, the power energy storage on the market usually adopts square cells. In order to improve the filling rate of the pole pieces, the permanent terminals are covered on the top cover. The top cover has electrode lead-out holes. After the cell components are installed, there is a vertical space for the electrode lead-out holes Idle, the space has not been effectively used, which is not conducive to the improvement of the energy density of the battery cell, the height of the terminal itself is set above the top cover sheet, occupying the vertical space of the module and other technical problems

Embodiment

[0057] Refer below Figure 1-Figure 7 The specific structure of the roof assembly of a specific embodiment of the present invention is described.

[0058] Such as figure 1 As shown, the top cover assembly includes a top cover sheet 1, a terminal pole 2, a seal 3, a lower plastic part 4, and an electrical connector 5. The top cover sheet 1 is provided with a pole fitting hole 11, and the pole fitting hole 11 Annular projections 12 are arranged at intervals along the circumferential direction on the inner side wall, matching projections 13 are provided on the upper surface of the top cover sheet 1 , and receiving grooves 14 are provided on the matching projections 13 . The lower surface of the top cover sheet 1 is provided with an escape groove 15 arranged around the pole matching hole 11 . The terminal pole 2 is penetrated in the pole matching hole 11, and has a first connection surface 221 and a second connection surface 211 oppositely arranged. The terminal pole 2 includes ...

Abstract

The invention discloses a top cover assembly, an assembling method of the top cover assembly and a battery, the top cover assembly comprises a top cover piece, a terminal post, a sealing piece, a lower plastic piece and an electric connecting piece, the top cover piece is provided with a post matching hole, the terminal post is arranged in the post matching hole in a penetrating manner and is provided with a first connecting surface and a second connecting surface which are oppositely arranged, and the sealing piece is arranged on the first connecting surface; the sealing piece is arranged on the terminal pole in a sleeving mode and clamped among the terminal pole, the inner circumferential wall of the pole matching hole and the upper surface of the top cover piece, the lower plastic piece is attached to the lower surface of the top cover piece, and the electric connecting piece is attached to the lower plastic piece and connected with the terminal pole. According to the top cover assembly, the overlapping height of the terminal post and the top cover plate is increased on the premise of ensuring insulation of the terminal post and the top cover plate, so that the energy density of a battery cell is improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a top cover assembly, a method for assembling the top cover assembly, and a battery. Background technique [0002] At present, the power energy storage on the market usually adopts square cells. In order to improve the filling rate of the pole pieces, the permanent terminals are covered on the top cover. The top cover has electrode lead-out holes. After the cell components are installed, there is a vertical space for the electrode lead-out holes Idle, the space has not been effectively used, which is not conducive to the improvement of the energy density of the battery cell, and the height of the terminal itself is set above the top cover sheet, occupying the vertical space of the module and other technical problems. Contents of the invention [0003] The first object of the present invention is to propose a top cover assembly, which increases the overlapping height of the te...
