Abstract
The utility model relates to batteries, in particular to a connecting sheet of the batteries, which comprises a connecting sheet body and a temperature fuse, wherein the connecting sheet body is electrically connected with the temperature fuse. The connecting sheet of the batteries has the benefit of sensing overheating produced by the connecting sheet body during abnormal operation through the temperature fuse, thereby cutting off a loop to avoid the occurrence of fire disasters.
Description
Technical field
The utility model relates to battery, relates in particular to the brace of a kind of battery of battery.
Background technology
The effect of brace is to connect between battery and the battery, and at present, existing brace does not have temperature protection, has potential safety hazard.
Summary of the invention
Do not have the problem of temperature protection in order to solve the brace of battery in the prior art, the utility model provides a kind of brace of battery.
The utility model provides a kind of brace of battery, comprises brace body and Thermal Cutoffs, and described brace body is electrically connected with described Thermal Cutoffs.
As further improvement of the utility model, described brace body is connected by spot welding with described Thermal Cutoffs.
As further improvement of the utility model, described Thermal Cutoffs is provided with welding pin, and described brace body is connected by spot welding with the welding pin of described Thermal Cutoffs.
As further improvement of the utility model, described welding pin has two at least.
As further improvement of the utility model, described brace body is corresponding one by one with described welding pin.
As further improvement of the utility model, described welding pin has two, and described brace body has two.
As further improvement of the utility model, two described welding pin lay respectively at the two ends of described Thermal Cutoffs.
As further improvement of the utility model, described Thermal Cutoffs is between two described brace bodies.
The beneficial effects of the utility model are: by such scheme, can respond to overheated that the brace body produces in improper running by Thermal Cutoffs, thereby cut-off loop is to avoid the generation of fire.
Description of drawings
Fig. 1 is the structural representation of the brace of a kind of battery of the utility model;
Fig. 2 is the structural representation of another embodiment of the brace of battery described in the utility model.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further specified.
Drawing reference numeral among Fig. 1 to Fig. 2 is: Thermal Cutoffs 1; Welding pin 11; Brace body 2.
As shown in Figure 1, a kind of brace of battery comprises brace body 2 and Thermal Cutoffs 1, and described brace body 2 is electrically connected with described Thermal Cutoffs 1.Wherein, described brace body 2 is the sheet metal shell fragment.
As shown in Figure 1, described brace body 2 and described Thermal Cutoffs 1 are connected by spot welding, are specially, and adopt spot welding machine that Thermal Cutoffs 1 and brace body 2 are welded together.
As shown in Figure 1, described Thermal Cutoffs 1 is provided with welding pin 11, the welding pin 11 of described brace body 2 and described Thermal Cutoffs 1 is connected by spot welding, is specially, and adopts spot welding machine that the welding pin 11 and the brace body 2 of Thermal Cutoffs 1 are welded together.
As shown in Figure 1, described welding pin has two at least.
As shown in Figure 1, described brace body is corresponding one by one with described welding pin.
To shown in Figure 2, described welding pin 11 can have two as Fig. 1, and described brace body 2 has two, and each brace body 2 is connected by spot welding with corresponding welding pin 11 respectively.
To shown in Figure 2, two described welding pin 11 lay respectively at the two ends of described Thermal Cutoffs 1 as Fig. 1, and promptly described Thermal Cutoffs 1 connects two described brace bodies 2 by two described welding pin 11.
To shown in Figure 2, described Thermal Cutoffs 1 is between two described brace bodies 2 as Fig. 1.
Because the heat resistance of Thermal Cutoffs 1 is poor, generally about 100 ℃, and the fusing point of the employed solder stick of soldering has reached 250 ℃, so high temperature can be destroyed Thermal Cutoffs 1 rapidly, carry out heat conduction so when soldering, need to clamp welding pin with tweezers, increased task difficulty, brace body 2 can't be fixed, be easy to generate skew during soldering, man-hour, cost was too big, and the solder stick cost is higher, the price of per kilogram approximately can reach 200 yuans, the cost of each tin point approximately can reach 0.08 yuan, therefore, is not suitable for adopting soldering to connect Thermal Cutoffs 1 and brace body 2.And adopt spot welding machine that the welding pin 11 and the brace body 2 of Thermal Cutoffs 1 are welded together, and can not produce high temperature, Thermal Cutoffs 1 just can not damage, reduce the consumption of solder stick, do not had the discharging of smog, energy-saving and emission-reduction, improved operating efficiency, reduced production costs.
The brace of a kind of battery that the utility model provides, can respond to overheated that brace body 2 produces in improper running by Thermal Cutoffs 1, thereby cut-off loop is to avoid the generation of fire, and, adopt the mode of spot welding machine spot welding that Thermal Cutoffs 1 and brace body 2 is welded together, can reduce the spoilage of Thermal Cutoffs 1, increase work efficiency; Owing to do not use solder stick, reduced production cost, also avoid the generation of toxic smog simultaneously, the effect of the energy-saving and emission-reduction that reach.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
