Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
A kind of top cover for lead-acid accumulator and the fit structure of terminal, including cell cover 15, angular copper tip 8, lead terminal post 4
With epoxide-resin glue part 1, described cell cover 15 is provided with the terminal base 14 for installing angular copper tip 8, described terminal base
14 are provided with U-shaped boss 7, L-type saddle 13 and the through hole 5 passing through for lead terminal post 4, and described lead terminal post 4 passes through through hole 5 and angular copper
Terminal 8 welds, and described angular copper tip 8 is divided into the fixed position 2 of level and vertical connecting portion 9, described fixed position 2 He
Connecting portion 9 is respectively provided with through hole, and the through hole 6 on described fixed position 2 passes through for lead terminal post 4, the through hole on described connecting portion 9
10 are connected with external cabling nose, and described epoxide-resin glue part 1 covers on described terminal base 14 surface and is filled in described terminal base
14 with the gap of angular copper tip 8.
In the present embodiment, described terminal base is provided with for through hole 5 top that lead terminal post 4 passes through coaxial with described through hole 5
Round recessed, described round recessed is placed with the sealing ring through lead terminal post.
In the present embodiment, on described terminal base 14 and angular copper tip 8, the through hole 5 of fixed position 2 is from up to down gradually
The connection conical bore expanding, the upper surface of connection conical bore on described angular copper tip 8 and hole wall are welded with described lead terminal post 4,
The described hole wall connecting conical bore is in close contact with lead terminal post outer surface, and fiting effect is more preferable.
In the present embodiment, described angular copper tip 8 is connected external cabling nose using bolts and nuts, dismounting side
