Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further：
A kind of copper bar high voltage protection set as Figure 1-Figure 2, including bottom 2, the embedded copper bar being arranged on bottom 2 top
3 and be located at copper bar 3 top and the top cover 1 being connected together with bottom 2.Described copper bar 3 includes the U-shaped copper bar that Open Side Down
Main body 31 and two copper installation portions 32 being separately positioned on copper bar main body 31 left and right sides, described copper installation portion 32 opens
It is provided with installing hole 33.The effect of copper bar is two power battery modules of series connection, is equivalent to wire；Installing hole is used for copper bar and power
Fixation between battery module.Described top cover 1 and bottom 2 are all using polypropylene material.The heat-shrinkable T bush of copper bar outer wrapping and copper
Row's directly contact, during battery charging and discharging and standing, the temperature of copper bar is in fluctuation status, and the change of temperature is easily caused
Material aging and expanding with heat and contract with cold, this requires that heat-shrinkable T bush has good ageing resistace and pliability.And polythene material
According to having preferable ageing resistace and pliability and cheap, therefore copper bar heat-shrinkable T bush adopts polythene material.And copper
Row's high voltage protection is enclosed within battery box structure copper bar is played a supporting role in protection, therefore using having poly- the third of higher intensity
Alkene.Described top cover 1 and bottom 2 are injection molding part.Copper bar 3 is wrapped by described top cover 1 and bottom 2, and is tied by buckle
Structure（The buckle on draw-in groove and bottom on top cover/）Realization is connected.
As shown in figure 3, described top cover 1 includes the cell body 11 that Open Side Down, is separately positioned on the gear at cell body 11 about two ends
Draw-in groove 12 on plate 13 and both sides side wall before and after being arranged on cell body 11.The left and right at described cell body 11 top is respectively arranged at two ends with one
Groove 14, this groove is used for copper bar is played with constraint and spacing effect.On the side wall of both sides before and after described cell body 11 respectively
Offer a breach 15, this breach is to radiate and saving material.As shown in figure 1, under the side wall two ends of cell body side
Gap is left, for the signal wire harness slot milling for BMS in end.Described baffle plate and cell body surround the sealing of a lower ending opening
Chamber, this annular seal space is located at the top of copper bar and bottom, can by fully wrapped around for copper bar live, improve insulating properties.
