【Embodiment】
In order that the purpose of this utility model, technical scheme and advantageous effects become apparent from understanding, below in conjunction with attached
Figure and embodiment, the utility model is further elaborated.It should be appreciated that described in this specification
Embodiment is not intended to limit the utility model just for the sake of explaining the utility model.
Referring to Fig. 2, Novel busbar 1 of the present utility model, including backflow portion 10, the backflow that is connected with the backflow portion 10
Protection portion 20 and the backflow row's fixed part 30 being connected with the back flow protection portion 20, the back flow protection portion 20 uses low melting point
Metal is made.When so occurring short-circuit inside battery bag, the back flow protection portion 20 will be fast due to the design of its low melting point
Fast thawing breaks, it is possible to achieve quick to disconnect protection battery modules and battery bag, it is ensured that its security.Preferably, the backflow is protected
Shield portion 20 is using low-melting-point metals such as aluminium or magnesium.
Preferably, in order to increase the fusing speed in back flow protection portion 20 when occurring short-circuit, the back flow protection portion 20 is adopted
Designed with hollow out.
Specifically, as shown in figure 3, the back flow protection portion 20 uses the structure of cross network, so inside battery bag
When there are short circuit and other problemses, these cross network bus structures simultaneously switch off, and can quickly protect battery modules and electricity
Chi Bao.
Specifically, as shown in figure 4, the back flow protection portion 20 use wrong row's formula bus structure, also can occur it is short-circuit when,
Accelerate the fusing in back flow protection portion 20, reach the purpose of protection battery bag.
Specifically, as shown in figure 5, the back flow protection portion 20 can also use the bus structure of multi-line formula, to realize soon
The disconnected purpose of fast thawing.
Further, as shown in Fig. 2 mounting hole 31 is provided with the backflow row fixed part 30, for will be described new
Bus-bar 1 is fixed in battery modules.
The utility model also proposed a kind of battery bag, and battery mould in battery bag is realized using above-mentioned Novel busbar 1
Electrical connection and short-circuit protection between group.Specifically, as shown in fig. 6, the battery bag, including multiple battery modules 40 and above-mentioned new
