Abstract
The utility model relates to a battery detection device and discloses a clamp for testing the internal resistance and the voltage in a battery pack. The clamp comprises an insulation base plate, wherein two lower current-conducting plates are disposed on the upper surface of the base plate at a certain interval; a driving device is suspended above the base plate; the driving device is in driving connection with an insulation top plate and is used for driving the driving insulation top plate to move up and down in a manner of parallel to the base plate; at least one through hole is disposed at each projection position of each lower current-conducting plate on the insulation top plate; a guide rod is axially movably disposed in the through hole; a reset spring is sleeved on the guide rod; an upper current-conducting plate is fixedly disposed at the lower end of the guide rod and is parallel to the lower current-conducting plate; each lower current-conducting plate and each upper current-conducting plate which is vertically opposite to each other are respectively communicated with the same work lead. The clamp for testing the internal resistance and the voltage in the battery pack effectively solves the problem of low set-matching quality caused by unstable internal resistance/voltage tests during a set-matching process.
Description
Technical field
The utility model relates to battery detecting equipment, especially relates to the anchor clamps of testing internal resistance, voltage among a kind of battery PACK.
Background technology
Battery PACK operation is divided into preceding processing, assembling, packing three parts, will carry out internal resistance, voltage, capacity and size to electric core and detect in the PACK operation.Traditional method is to adopt conventional anchor clamps, last lower plate all adopts the copper coin design, wherein lower plate is fixed on the worktable of insulation, and train wheel bridge is fixed on the piston rod of cylinder by insulcrete, thus moving up and down clamping or unclamping the lug of electric core to be measured by the control piston bar.This anchor clamps are when test internal resistance/voltage, because the flatness of the thickness of lug or lug is inconsistent, it is compacted to be easy to generate a lug, and another but has loosening phenomenon, and the internal resistance voltage that causes testing out all has problem; And in use for some time, because the copper coin serious wear because loose contact causes the phenomenon of internal resistance/voltage fluctuation more serious, has had a strong impact on the precision of combo, the quality after the electric core combination can't guarantee.
The utility model content
For overcoming above-mentioned shortcoming, the utility model provides a kind of anchor clamps that can accurately measure electric in-core resistance, voltage in battery PACK.
The purpose of this utility model is achieved through the following technical measures, test internal resistance among a kind of battery PACK, the anchor clamps of voltage, comprise insulating base, described plate upper surface is arranged at intervals with two lower conducting plates, a drive unit has suspended above the described base plate, described drive unit drives and connects an insulation top board, being used for driving the parallel base plate of insulation top board moves up and down, each projection place that described lower conducting plate is positioned at the insulation top board is provided with a through hole at least, axially be movably set with a guide rod in the described through hole, be arranged with a back-moving spring on the described guide rod, the parallel lower conducting plate in the lower end of described guide rod is set with current-carrying plate on; The lower conducting plate of described correspondence up and down is communicated with by identical work lead respectively with last current-carrying plate.
As a kind of optimal way, each projection place that described lower conducting plate is positioned at the insulation top board is provided with two through holes.
Concrete, described lower conducting plate and last current-carrying plate are copper coin.
Concrete, described drive unit is cylinder, described insulation top board is fixed on the piston rod.
Concrete, described guide rod is the copper rod of diameter 4mm.
The utility model adopts the guide rod of band back-moving spring and last current-carrying plate as train wheel bridge, thereby no matter whether the lug thickness of electric core changes, dynamics and the contact area of each contact are constant basically, and the result of test is more stable; In the use, even current-carrying plate has worn and torn, can not influence the test effect yet, thereby solve effectively in the combo process because the combo phenomenon of low quality that internal resistance/the voltage tester instability causes.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A partial enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
As Fig. 1, test the anchor clamps of internal resistance, voltage among a kind of battery PACK, comprise insulating base 5, base plate 5 upper surfaces are arranged at intervals with conductive copper plate 4 two times, a cylinder 1 has suspended above the base plate, one insulation top board 2 is fixedly arranged on the piston rod of cylinder 1, and cylinder 1 work then drives insulation top board 2, and parallel base plate 5 moves up and down.With reference to figure 2, conductive copper plate 4 places are provided with two through holes 201 respectively under 2 projections of insulation top board, the axial movable copper rod 302 that is provided with a diameter 4mm that connects in the through hole 201, the upper end that copper rod 302 is positioned at insulation top board 2 is provided with a clamp 101 greater than through hole 201, the lower end that copper rod 302 is positioned at insulation top board 2 is arranged with conductive copper plate 304 in parallel, copper rod 302 top wedging rings are provided with a back-moving spring 303, and the following conductive copper plate 4 of described correspondence up and down is communicated with by identical work lead respectively with last conductive copper plate 304.
The utility model adopts the copper rod (diameter 4mm) of band spring function as train wheel bridge, no matter whether the lug thickness of electric core changes, dynamics and the contact area of each contact are constant basically, and the result of test is more stable; In the use, even upper and lower conductive copper plate has worn and torn, can not influence the test effect yet, solve in the combo process because the combo phenomenon of low quality that internal resistance/the voltage tester instability causes.
More than be that the anchor clamps of testing internal resistance, voltage among the utility model battery PACK are set forth; be used for helping to understand the utility model; but embodiment of the present utility model is not restricted to the described embodiments; anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
