The sectional area of protection zone preferably, being provided with some through holes in described protection zone, is reduced by arranging through hole, And loose structure is conducive to the fracture of protection zone.
The sectional area of protection zone preferably, the both sides of described protection zone are provided with recess, is reduced by arranging recess, Be conducive to the fracture of protection zone.
Preferably, the minimum thickness of described protection zone is less than described master tape bonding pad and the described minimum with bonding pad Thickness, reduces the sectional area of protection zone by reduce thickness, is conducive to the fracture of protection zone.
Preferably, described protection zone is provided with circular arc with described master tape bonding pad and the described junction with bonding pad Transition zone, circular arc excessively makes nickel strap in normal work, and heating is evenly distributed it is therefore prevented that breaking occurs in protection zone under normal work Situation about splitting.
Preferably, being provided with connecting hole in described master tape bonding pad, described master tape body is provided with location hole, described master Fixed by securing member, connecting hole and location hole between band bonding pad and described master tape body so that battery cell can independent quilt Dismounting, after single battery cell is damaged, can be convenient for changing battery cell.
Preferably, being provided with the protection board being made from an insulative material between described adjacent guardbands, when protection zone fracture Can prevent the belt body coming off from snapping on adjacent battery cell afterwards, thus causing the situation of adjacent cell monomer short circuit.
In sum, the beneficial effects of the utility model:
1. a kind of battery pack nickel belt structure described in the utility model, improves the security of battery pack, can be unexpected short After road situation occurs, disconnect problem battery cell immediately, protect whole battery pack.
2. a kind of battery pack nickel belt structure described in the utility model, changes power supply single convenient, by the company of securing member Connect mode, only need to be individually replaced problem battery cell so that it may quickly repair battery pack.

Specific embodiment
Specific examples below is only to explanation of the present utility model, and it is not to restriction of the present utility model, this Skilled person can make to the present embodiment after reading this specification as needed does not have the modification of creative contribution, But as long as all being protected by Patent Law in right of the present utility model.
With embodiment, the utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment 1:
According to Fig. 1, Fig. 2, a kind of battery pack nickel belt structure, comprising: multiple bands on master tape body 1 and master tape body 1 Body 2, is provided with protection band 3 between master tape body 1 and a belt body 2, the two ends of protection band 3 are solid with master tape body 1 and a belt body 2 respectively Fixed, the minimum cross-sectional area of protection band 3 is less than the minimum cross-sectional area of a belt body 2 and master tape body 1.
Protection band 3 include in order to be connected with master tape body 1 master tape bonding pad 31, the band in order to be connected with belt body 2 Bonding pad 32 and the protection zone 33 in order to protect battery, a band bonding pad 32 is welded and fixed with battery cell 5, master tape bonding pad 31 It is welded and fixed with master tape body 1, be welded and fixed more firm, battery loose contact can be avoided.
