Abstract

The utility model belongs to the technical field of battery manufacture, and particularly relates to a battery. The battery comprises a casing and poles, wherein the poles are led out of the battery; the outer ends of the poles are positioned outside the casing; the poles outside the casing are riveted with a connecting strip through rivets; and the connecting strip is in plug-in fit with a plug connector. The utility model further provides a battery pack formed by assembling a plurality of the batteries, the adjacent batteries are connected through lead wires to achieve conduction, and the ends of the lead wires are connected with the plug connectors. In the utility model, the poles in the battery can not rotate easily and are positioned firmly, so that during the practical use of the battery, the internal resistance does not change, accordingly, the service performance of the battery is improved. Besides, when the batteries are assembled to form the battery pack, the connection structure is simple, the operation is convenient, the time is saved and the cost is cut.

Description

Battery and battery pack

Technical field

The utility model belongs to battery manufacturing technology field.

Background technology

Existing battery in actual use, as replacing, vibrations etc., its inner pole is moving easily, thereby causes the variation of the internal resistance of cell, has reduced battery performance.In addition, the connection of existing battery in groups the time also bothers, and needs to twist the parts of screw rod and bus and so on, causes battery to operate inconvenience in groups, and be time-consuming and take cost.

Summary of the invention

The utility model discloses a kind of battery and battery pack, it has solved above-mentioned technical problem.

The utility model is taked following technical scheme: battery, comprise housing, pole, and battery is drawn pole, and the pole outer end is in outside the housing, and the pole that is in outside the housing passes through rivet one intercell connector, and this intercell connector is pegged graft with a plug connector and is cooperated.

Preferably, intercell connector forms a hook, and this hook has a location hole; The bottom dual-side of described plug connector leaves the gap along inwardly being circular-arc bending between the edge of this bending part and the body of plug connector, the hook of the suitable and insertion intercell connector of the hook thickness of this gap and intercell connector; Described plug connector forms a reference column, and this reference column buckles into the location hole of intercell connector.

Preferably, two edges, top of plug connector extend forward and form two sidewalls.

Preferably, housing is cuboid.

The utility model also provides a kind of battery pack that is assembled by several aforementioned batteries, and adjacent cell links to each other and conducting by lead, and the termination of lead and described plug connector link.

Preferably, two edges, top of plug connector extend forward and form two sidewalls; The termination of described lead is inserted between the two side, top of plug connector, and the two side is compressed the termination of lead by external force.

The pole of the utility model inside battery is difficult for rotating, the pole firm position, and in the actual use of battery, its internal resistance can not change, thereby has improved the serviceability of battery.In addition, battery is in groups the time, and its syndeton is simple, easy to operate, saves time and reduces cost.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Shown in Fig. 1-12, the battery pack of present embodiment is made of two batteries, and the housing 1 of single battery is flat-shaped cuboid, and it adopts metal or plastics to make, with heat radiation that improves battery and the volume of saving whole battery group.Pole is respectively drawn in the both sides of housing 1 one (sides), the pole of every side is by rivet 5 riveted joint intercell connectors 2 (having two rivet holes 21 on the intercell connector 2), like this, make that inner pole is difficult for rotating, the pole firm position, in the actual use of battery (as battery, vibrations etc.), its internal resistance can not change, thereby has improved the serviceability of battery.

Intercell connector 2 forms a hook, this bending hook part has a location hole 22, the bending hook part of intercell connector 2 plug connector 3 of pegging graft, bottom 31 dual-sides of plug connector 3 are along inwardly being circular-arc bending, leave the gap between the body of bent end edge and plug connector 3, the bending hook part thickness of this gap and intercell connector 2 is suitable, and the bending hook part of intercell connector 2 is inserted in this gap.Plug connector 3 forms a reference column 32, and this reference column 32 buckles into the location hole 22 of intercell connector 2.Intercell connector 2 adopts to patch with plug connector 3 and cooperates, and its syndeton is simple, easy to operate, and the cost-saving saves time.During connection, only need that plug connector 3 is inserted intercell connectors 2 and get final product, and cooperating of corresponding spacer and location hole arranged, assurance in use the phenomenon of both disengagings can not occur.

33 liang of edges, the top of plug connector 3 extend forward, are two parallel sidewalls.When a plurality of batteries in groups the time; link to each other by lead 4 between adjacent cell and conducting (lead 4 comprises BMS connecting line and conductor wire; the BMS connecting line is used to protect battery; prevent super-charge super-discharge); the termination of lead 4 is inserted between the two side, top of plug connector 3, and by external force the two side is compressed the line termination.

Those of ordinary skills will be appreciated that the utility model is not limited to the foregoing description, any conversion of the present utility model, modification are all fallen into protection range of the present utility model.
