Description
Technical field
The utility model relates to a kind of lithium-ion-power cell, especially a kind of lithium ion power pole anti-rotation battery.
Background technology
Lithium-ion-power cell positive and negative pole in being assembled into the process of battery pack adopts thread connecting mode to couple together, also can adopt the spot welding connected mode, but the spot welding ease of connection causes the pole heating, and cause the stressed loosening cell sealing effect that influences of pole when being threaded in the process of connection positive and negative pole clamp nut of single battery or bolt easily, thereby cause battery gas leakage, the internal resistance of cell increases, and the internal short-circuit of battery that causes of a serious nature causes potential safety hazard.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and the lithium-ion-power cell that battery electrode column can not rotate when a kind of being threaded was provided makes battery have good sealing property, fail safe and practicality.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of lithium-ion-power cell, comprise positive and negative battery electrode column and the battery case of fixedlying connected with positive and negative battery electrode column, described positive and negative battery electrode column links together by nut and copper bar, all be socketed with torsional stop on the described positive and negative battery electrode column, this torsional stop is fixedlyed connected with battery case, described positive and negative battery electrode column is provided with male member, described torsional stop be provided with positive and negative battery electrode column on the male member corresponding grooves, described male member is connected in the described groove.
Further, described torsional stop is the polypropylene torsional stop; Described male member is anti-turning handle; Described torsional stop is between battery case and copper bar.
The beneficial effects of the utility model: the utility model has solved the defective that exists in the background technology, after the positive and negative pole of lithium-ion-power cell and the clamping of polypropylene torsional stop, when the nut on the fastening pole causes pole stressed, anti-turning handle passes to the polypropylene torsional stop with power, the polypropylene torsional stop can bear high pulling torque, and power is transferred to battery case, battery case itself has enough intensity, thereby battery electrode column can not rotated when stressed, improved sealing, fail safe and the good practicality of battery.
