Abstract
The utility model relates to the manufacture technical field of a lithium ion battery and especially relates to a tool for testing a power battery. The tool comprises a housing and connection sheets, wherein the housing matches an upper portion of a lithium ion battery and is equipped with spacing holes that allow the connection sheets to pass through. Each connection sheet is L-shaped. One edge of each connection sheet is equipped with a test hole that is connected with an external battery test wire, and the other edge of each connection sheet is equipped with a pole through hole that is convenient for battery poles to pass through. A side wall of the housing is provided with locking bolts that are used for fixing a battery case. According to the tool for testing the power battery, improvements are made based on the welding connection sheets, thus avoiding operation of the welding connection sheets before a test; the positive and negative poles are prevented against short circuits, the connection sheets are prevented from shedding, etc, thereby enhancing safety during a test process; and errors caused by the test tool are avoided.
Description
Technical field
The utility model relates to technical field of lithium-ion battery, relates in particular to a kind of electrokinetic cell frock.
Background technology
Advantages such as lithium ion battery has voltage height, specific energy height, recycles often, storage time is long, not only at portable electric appts, be used widely as mobile phone, Digital Video and laptop computer, and be widely used in big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool, so the safety requirements of lithium ion battery is more and more higher.Because electrokinetic cell generally all has high voltage and jumbo characteristics, often will carry out the charge-discharge test of big multiplying power, guarantee that the high security of test and the high accuracy of test result are very necessary.Though use the method be welded to connect sheet can finish test in the prior art, the making of contact pin and welding make the set-up procedure of the test safety inadequately that becomes, complex steps; And the quality of welding has also influenced the result of test, and can't avoid the come off problem of brace in test process; With this understanding, brace becomes a kind of consumables, and the battery after the welding also can't reduce.Therefore need a kind of have safety, electrokinetic cell test fixture efficiently.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of electrokinetic cell frock is provided, and can carry out high-current test and need not change brace frequently lithium ion battery.
The utility model for achieving the above object, by the following technical solutions: a kind of electrokinetic cell frock comprises the housing and the brace that are complementary with lithium ion battery top; Described housing is provided with for the spacing hole that guarantees that described brace passes; Described brace is L-shaped, and a limit of described brace is provided with the instrument connection that is connected with the external cell p-wire, and another limit is provided with is convenient to the pole through hole that battery electrode column passes through; The sidewall of described housing is provided with for the clamping screw that battery case shell is fixing.
The part that described brace is connected with battery cover board is provided with the projection contact of conduction, and compresses by spring and the battery cover board that is arranged between brace and housing.
Described housing adopts the bakelite material.
The beneficial effects of the utility model are: the utility model is simple in structure, adopts the electrokinetic cell frock of the utility model structure, improves on the basis that is welded to connect sheet, has avoided being welded to connect before the test operation of sheet; Also prevent the generation of phenomenon such as come off of both positive and negative polarity short circuit, brace in the test process, strengthened test process security, avoided the error that causes owing to test fixture; In addition, use this frock and can repeat different batteries are tested, avoid the waste of brace, also make the preceding preliminary work of battery testing simpler simultaneously, provide a kind of instrument easily for safe, the efficient test that realizes electrokinetic cell.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is internal view of the present utility model;
Fig. 3 is brace outside drawing of the present utility model.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1; electrokinetic cell frock of the present utility model; the brace 2 that it comprises housing 1 and is used for battery testing, described frock size is slightly larger than battery size, can just cover the battery upper end; can protect the positive and negative terminals of battery; simultaneously leave spacing hole 5 on frock top over against the position of electrode, the width in hole is 1mm, and length is slightly larger than brace 2; can guarantee that like this brace 2 can pass through spacing hole smoothly, reach the purpose that is communicated with battery electrode and p-wire.Described housing 1 is provided with a pair of clamping screw 3 in a side, clamping screw must be screwed in test process, prevents that battery and housing break away from.
As shown in Figure 2, described frock is equipped with two springs 6 in inside, and the position of spring 6 should be corresponding with the position of battery electrode column, and the diameter of spring must be greater than the diameter of pole.In the process of using, spring 6 is pressed on brace 2 on the cover plate of battery, guarantees that brace contacts well with electric lids.
As shown in Figure 3, described brace 2 thickness are 0.7mm, are that the rectangle foil obtains through bending 90 °, and brace 2 two ends are left instrument connection 4 and pole through hole 8 respectively, instrument connection 4 namely is used for the connection of battery testing line, and the diameter of pole through hole 8 must be slightly larger than the pole diameter.The end that brace 2 contacts with electric lids is the cylindrical projections contact 7 of dense arrangement, and under the pressuring action of spring 6, the contact 7 of these projections can closely contact with battery cover board, reaches and is welded to connect the effect that contacts that sheet compares favourably.
The material of described housing 1 is selected bakelite for use but is not limited to bakelite, and the insulating effect of this thermosetting macromolecule material is apparent, and bakelite has higher, the cheap advantage of intensity, and like this, the manufacturing cost of frock can reduce greatly.
The material of described brace 2 is selected for use to copper but is not limited to copper, metallic copper has the good electric conductivity that is only second to noble metal, in order to prevent the brace oxidation, can be chosen in the brace surface gold-plating, especially oxidation will be avoided in the contact that contacts with electric lids, to guarantee quality of connection.The thickness of brace 2 is 0.7mm.
Frock main body 1 and brace 2 are namely done as a whole, before test, battery are stretched into frock by the electrode direction of illustrating, make battery electrode column pass through pole through hole 8, then battery and frock are compressed the fastening bolt 3 that screws.Instrument connection 4 connects p-wire can carry out test operation later on.
Adopt the electrokinetic cell frock of the utility model structure, improve on the basis that is welded to connect sheet, avoided being welded to connect before the test operation of sheet; Also prevented the generation of phenomenon such as come off of both positive and negative polarity short circuit, brace in the test process; In addition, use this frock and can repeat different batteries are tested, avoid the waste of brace, also make the preceding preliminary work of battery testing simpler simultaneously, provide a kind of instrument easily for safe, the efficient test that realizes electrokinetic cell.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
