According to the lithium battery provided by the utility model, two positive electrode output ends and two negative electrode output ends of one battery can be realized by virtue of the positive connector and the negative connector; during the production of the battery, the positive connector and the negative connector are arranged in the shell and are in welded connection, so that the appearance of the lithium battery after packaging is beautiful, and the connection of the internal circuit is also reliable; additionally, the positive plates and the negative plates are arranged in different sections, and are separated from each other as far as possible, so that short circuit is reduced.

Description

A kind of lithium battery
Technical field
The utility model relates to lithium battery, especially has the lithium battery of two positive poles and two negative poles.
Background technology
Existing lithium battery all only has a positive pole and cathode output end, and this battery can only provide a road output.But need a battery to provide two-way output just can meet the demands in some occasion, and this only has the lithium battery of a road output obviously to can not meet at present, if realize two-way output, can only rely on wire to connect and create another road output, it is complicated that such battery structure can become, and circuit exists the danger of short circuit.In addition, the lithium battery that only has an output is anodal or touch while damaging, although the performance of inside battery is intact, and electric weight is pure, and battery also cannot re-use, thereby causes the waste of resource.
Summary of the invention
For solving the problems of the technologies described above, the technical solution of the utility model is to provide a kind of lithium battery, has two positive poles and two negative poles, and simple in structure.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of lithium battery, and comprise housing, be located at battery core and protective circuit plate in described housing, described housing is cylindrical, the two ends of housing are provided with positive plate, and described positive plate is connected with the positive pole of battery core by positive strap; The both sides of described battery core are provided with negative plate, and described negative plate is connected with battery core negative pole by negative pole brace; On described housing, corresponding described negative plate place is provided with opening, and described negative plate exposes outside housing by described opening.The utility model utilizes positive strap and negative pole brace to realize a battery to have the output of two positive poles and two negative poles; Battery, in the time producing, is just located at positive strap and negative pole brace in housing and with being welded to connect, and make the lithium battery outward appearance after encapsulation more good-looking, and its internal circuit connects also reliable.In addition, positive plate is arranged on different regions from negative plate, and what the two was tried one's best separates, and reduces situation about being short-circuited and occurs.Lithium battery of the present utility model is that plug-in uses, and when after the positive pole oxidation or damage of one end, can change the other end into.In addition, battery, in the time of charging, can insert charging in two ends, regardless of direction, safe and reliable.
As improvement, described negative plate is curved.
As improvement, between described negative pole brace and positive plate, be provided with insulation cushion, guarantee that anodal and negative pole can not be short-circuited.
As improvement, described shell protective circuit plate is arranged on one end of battery core, between backplate circuit board and battery core, is provided with insulation cushion.
The beneficial effect that the utility model compared with prior art brought is:
The utility model utilizes positive strap and negative pole brace to realize a battery to have the output of two positive poles and two negative poles; Battery, in the time producing, is just located at positive strap and negative pole brace in housing and with being welded to connect, and make the lithium battery outward appearance after encapsulation more good-looking, and its internal circuit connects also reliable.Positive plate is arranged on different regions from negative plate, and what the two was tried one's best separates, and reduces situation about being short-circuited and occurs.Battery, in the time of charging, can insert charging in two ends, regardless of direction, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, a kind of lithium battery, comprises housing 1, is located at battery core 2 and protective circuit plate 8 in described housing 1.Described housing 1 is cylindrical, and similar to battery core 2 shapes, the two ends of housing 1 are provided with positive plate 3, and described positive plate 3 is connected with the positive pole of battery core 2 by positive strap 5, between positive plate 3 and positive strap 5, adopts and is welded to connect; The both sides of described battery core 2 are provided with the negative plate 4 of arc, and described negative plate 4 is connected with battery core 2 negative poles by negative pole brace 6, and negative plate 4 is structure as a whole with negative pole brace 6; On described housing 1, corresponding described negative plate 4 places are provided with opening, and described negative plate 4 exposes outside housing 1 by described opening.Between described negative pole brace 6 and positive plate 3, be provided with insulation cushion 7, guarantee that anodal and negative pole can not be short-circuited.Described shell protective circuit plate 8 is arranged on one end of battery core 2, between backplate circuit board and battery core 2, is provided with insulation cushion 9.
The utility model utilizes positive strap 5 and negative pole brace 6 to realize a battery to have the output of two positive poles and two negative poles; Battery, in the time producing, is just located at positive strap 5 and negative pole brace 6 in housing 1 and with being welded to connect, and make the lithium battery outward appearance after encapsulation more good-looking, and its internal circuit connects also reliable.In addition, positive plate 3 is arranged on different regions from negative plate 4, and what the two was tried one's best separates, and reduces situation about being short-circuited and occurs.Lithium battery of the present utility model is that plug-in uses, and when after the positive pole oxidation or damage of one end, can change the other end into.Battery, in the time of charging, can insert charging in two ends, regardless of direction, safe and reliable.
