Abstract
The utility model discloses a battery internal resistance detector comprising a pedestal. The detector is characterized in that probe fixing seats mounted on the pedestal comprise a left probe fixing seat and a right probe fixing seat, that probes contacting the electrodes of a detected battery are oppositely mounted on the left probe fixing seat and the right probe fixing seat, and that a detected battery fixing seat disposed on the pedestal is located between the left probe fixing seat and the right probe fixing seat. The battery internal resistance detector is not only easy to manipulate, but also has high measurement accuracy.
Description
Technical field
The utility model relates to a kind of detector, relates in particular to a kind of internal resistance of cell detector.
Background technology
The internal resistance of battery is the important parameter of battery, and it not only reflects the nuclear power state that battery is current, and the degradation of reflection battery.So before using battery, its internal resistance detected and seems particularly important, yet, traditional internal resistance of cell detector in use still has various weak points, thereby can't satisfy the needs of practical application, for example: the Chinese patent Granted publication number is CN201903589U, Granted publication day is that on 07 20th, 2011 utility model patent discloses a kind of lithium ion battery internal resistance testing fixture, its objective is and improve detection speed and work efficiency, the technical scheme that for this reason adopts is: arrange corresponding just with battery plus-negative plate to be detected position in the frock housing, negative sheet metal, with this just, negative sheet metal is connected with voltage internal resistance table by wire.During use, battery to be detected directly is placed in the frock housing can shows internal resistance of cell reading, although improved detection speed and work efficiency, the structure of this kind device is too simple, thereby causes its less stable, and measuring accuracy is lower.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of easy to operate, internal resistance of cell detector that measuring accuracy is higher.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of internal resistance of cell detector, comprise base, the probe holder is installed on the described base, described probe holder comprises left probe holder and right probe holder, being equipped with and the contacted a plurality of probes of the electrode of tested battery in opposite directions on described left probe holder and the described right probe holder, described a plurality of probe evenly is spaced and dismountable being installed on described left probe holder and the described right probe holder, dismountable on the described base tested battery mounting is installed, described tested battery mounting is positioned in the middle of described left probe holder and the described right probe holder.
Be connected with respectively on described left probe holder and the described right probe holder and drive its drive unit that slides at described base.
Described drive unit is cylinder.
Compared with prior art, the beneficial effects of the utility model are:
1. because internal resistance of cell detector of the present utility model is provided with left probe holder and right probe holder, be separately installed with a plurality of probes on this left probe holder and the right probe holder, and dismountable tested battery mounting is installed in the middle of left probe holder and right probe holder, during use, at first tested battery is fixed on the tested battery mounting by frock, probe on left probe holder and the right probe holder is contacted with the electrode of tested battery respectively, finally finish the detection of the tested internal resistance of cell, the phenomenon that can not occur tested battery and probe loose contact in this process, do not survey or the inaccurate phenomenon of test result thereby mistake can not occur, so the utility model is easy to operate, measuring accuracy is higher.
2. because all detachably settings of internal resistance of cell detector middle probe of the present utility model and tested battery mounting, thereby can adjust number of probes or change tested battery mounting according to the specification of tested battery in use, thereby can be suitable for the internal resistance test of all size battery, so the utility model uses, and dirigibility is higher, applicability is wider.
Description of drawings
Describe the utility model in detail below in conjunction with drawings and embodiments:
Fig. 1 is the utility model structural representation.
Among the figure: base 10, probe holder 12, tested battery mounting 14, left probe holder 16, right probe holder 18, probe 20.
Embodiment
As shown in Figure 1, a kind of internal resistance of cell detector of the present utility model, include base 10, probe holder 12 and tested battery mounting 14, its middle probe holder 12 and tested battery mounting 14 are installed on the base 10, probe holder 12 includes on left probe holder 16 and this left probe holder 16 and the right probe holder 18 being equipped with and the contacted a plurality of probes 20 of the electrode of tested battery in opposite directions, these a plurality of probes 20 evenly are spaced and dismountable being installed on left probe holder 16 and the right probe holder 18, tested battery mounting 14 is dismountable be installed on the base 10 and be positioned at left probe holder 16 and right probe holder 18 in the middle of, for easy to operate, be connected with respectively on left probe holder 16 and right probe holder 18 and drive its drive unit that slides at base 10 (for diagram), preferred drive unit is cylinder.
During actual the use, at first tested battery is fixed on the tested battery mounting 14 by frock, then the probe on left probe holder 16 and the right probe holder 18 is contacted respectively with the electrode of tested battery, finally finish the detection of the tested internal resistance of cell, can not occur the phenomenon of tested battery and probe loose contact in this process, not survey or the inaccurate phenomenon of test result thereby mistake can not occur.
In sum, the utility model is not only easy to operate but also measuring accuracy is higher.
The above only is preferred embodiments of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
