Root on be fixed with aluminium flake；The insulation spacer is set between the manufactured head of rivet and cover plate main body；The insulation board is set
It is placed between aluminium flake and cover plate main body；The insulation tube is dissolved in mounting hole, and one end is connect with insulation spacer, the other end and absolutely
Listrium connects, and the locating piece for positioning aluminium flake is provided on the insulation board two sides.
Further, the locating piece is provided with the chamfering for reducing friction close to the side of aluminium flake.
Wherein, the chamfering is arc surface.
Further, the other side of the locating piece opposing insulation plate is provided with the convex block towards aluminium flake, the convex block with
Collets form the slideway slid into for aluminium flake.
Further, the circular shape of the protrusion is round or rectangle.
Further, the left side of the cover plate main body outer end face is equipped with liquid injection hole.
It, can be from convex the utility model has the beneficial effects that: the utility model be when aluminium flake will be encased in insulation board
It slides into the slideway that block is formed with collets, by the way that under convex block and insulation board collective effect, aluminium flake is clamped, better plays
Installation is facilitated to the position-limiting action of aluminium flake, simultaneously as the effect of convex block, so that aluminium flake other than it will not arbitrarily rotate, is gone back
It avoids in riveting process, because rivet force is excessive, aluminium flake is caused to deviate from from insulation board, sent out on the riveting direction of rivet
Raw displacement is arranged such the installation for more effectively facilitating battery cover board and practical, improves work efficiency, and can be accurate
Ground installation.
In addition, the protrusion of manufactured head lower end surface can generate the lower pressure reinforced to insulation spacer, even if the pressure of riveting
The slightly surface irregularity of deviation or insulation spacer also can guarantee the reliability of riveting, will not generate gap, can avoid electricity completely
The leakage of pond electrolyte, sealing performance are very reliable；And the design of "-" type mouth, convenient for being used when user's disassembly.

Specific embodiment
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below
In conjunction with accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific implementation described herein
Example is only used to explain the utility model, is not used to limit the utility model.
Please refer to shown in Fig. 1-3, the utility model about a kind of from rushing metal rivet, including cover plate main body 10, rivet 20,
Insulation spacer 30, insulation board 40, insulation tube 50 are provided with the mounting hole 11 for installing anode contact, riveting on cover plate main body 10
Nail 20 is arranged on insulation tube 50, the rivet 20 include manufactured head 21 with the root 22 that is connected, under the manufactured head 21
End face is equipped with a circle protrusion 60 around root, constitutes sealing reinforcement structure, is provided with "-" type notch in the upper surface of manufactured head 21
70, and aluminium flake 80 is fixed on the root of rivet 20 22, insulation spacer 30 is set to the manufactured head 21 and lid of the rivet 20
Between plate main body 10, insulation board 40 is set between aluminium flake 80 and cover plate main body 10, and insulation tube 50 is dissolved in mounting hole 11, one
End is connect with insulation spacer 30, and the other end is connect with insulation board 40, is provided on 40 two sides of insulation board for positioning aluminium flake
80 locating piece 90.
Further, the locating piece 90 is provided with the chamfering 91 for reducing friction close to the side of aluminium flake 80.In aluminium
Piece 80 is encased in during insulation board 40, and there is sharp face at the edge on aluminium flake 80, can wear the locating piece 90 on insulation board 40, is led to
It crosses chamfering 91 and facilitates aluminium flake 80 and be encased in insulation board 40, and reduce the sharp friction in face of locating piece 90 of aluminium flake 80,
Wherein chamfering 91 is that the frictional force of arc surface is minimum, can play the effect of best gap friction.Wherein, the chamfering of the present embodiment
For arc surface.
Further, please refer to shown in Fig. 3, as another embodiment, the 90 opposing insulation plate 40 of locating piece it is another
Side is provided with the convex block 120 towards aluminium flake 80, and the convex block 120 forms the slideway 100 slid into for aluminium flake 80 with collets, in aluminium
When piece 80 will be encased in insulation board 40, it can be slid into from the slideway 100 that convex block 120 is formed with collets, pass through convex block 120
Under 40 collective effect of insulation board, aluminium flake 80 is clamped, has better played the position-limiting action to aluminium flake 80, facilitates installation, together
When, due to the effect of convex block 120, so that aluminium flake 80 is other than it will not arbitrarily rotate, it is thus also avoided that in riveting process, because of riveting
Relay is excessive, and aluminium flake 80 is caused to deviate from from insulation board 40, is subjected to displacement on the riveting direction of rivet 20, and such setting more has
