AI Technical Summary
The electrode post is prone to sinking under external force, which causes changes in the compression of the sealing ring between the electrode post and the cover plate, affecting airtightness and easily causing leakage problems.
First and second connecting grooves are provided on the cover plate, and first and second insulating components are respectively embedded in them. The insulating components are fixed to the cover plate by injection molding, which restricts the movement of the pole post, prevents sinking, and ensures the sealing effect of the sealing ring.
It effectively prevents the terminal post from sinking, maintains the stability of the sealing ring's resistance and deformation, ensures that the battery's airtightness is not affected, and avoids leakage.

The electrode post mates with the mounting hole, and the opposite ends of the electrode post protrude relative to the first side and the second side, respectively. A first insulating element covers the portion of the pole that protrudes relative to the first side, and a portion of the first insulating element is embedded in the first connecting groove; and / or, The second insulating member covers the portion of the pole that protrudes relative to the second side, and a portion of the second insulating member is embedded in the second connecting groove.
2. The roof assembly of claim 1, wherein, The first insulating element includes a first protrusion that mates with the first connecting groove; the first protrusion is a cone, and the first connecting groove is a tapered groove; and / or, The second insulating element includes a second protrusion that mates with the second connecting groove. The second protrusion is a cone, and the second connecting groove is a conical groove.
3. The roof assembly of claim 1, wherein, The first insulating member is injection molded on the first side, and a portion of the first insulating member is filled into the first connecting groove; and / or, The second insulating component is injection molded on the second side, and a portion of the second insulating component is filled into the second connecting groove.
4. The roof assembly of any one of claims 1-3, wherein, The first connecting groove and the second connecting groove are offset in the thickness direction of the cover plate.
5. The roof assembly of any one of claims 1 to 3, wherein, The pole post has an annular groove recessed on the outer wall of the protruding portion on the first side, and a portion of the first insulating member is embedded in the annular groove.
6. The roof assembly of any one of claims 1 to 3, wherein, The outer wall of the pole post protruding from the second side is provided with an annular boss. The annular boss is spaced apart from the second side. A portion of the second insulating member is embedded in the area between the annular boss and the second side, as well as in the area of the annular boss away from the second side.
7. The roof assembly of claim 6, wherein, The distance A between the side of the second insulating member away from the second side and the side of the annular boss away from the second side in the height direction of the pole post is satisfied: 0.5mm≤A≤2mm.
8. The roof assembly of any one of claims 1-3, wherein, The portion of the pole protruding relative to the second side includes an exposed end that is exposed outside the coverage area of the second insulating member.
9. The roof assembly of claim 8, wherein, The length of the exposed end in the height direction of the pole post is B, and B satisfies: 0.2mm≤B≤1mm.
10. A battery, characterized by include: The outer casing has a receiving cavity; A battery cell is disposed within the receiving cavity, and the battery cell is provided with tabs; The top cover assembly as described in any one of claims 1 to 9 is disposed on the top of the housing, the top cover assembly being used to close the receiving cavity, and the pole being electrically connected to the tab.
