Abstract
The invention discloses a cell internal resistance detector which comprises a base, and is characterized in that the base is equipped with a probe fixing seat; the probe fixing seat comprises a left probe fixing seat and a right probe fixing seat; the probes in contact with electrodes of the detected cell are mounted on the left probe fixing seat and the right probe fixing seat oppositely; and a detected cell fixing seat is mounted on the base and located between the left probe fixing seat and the right probe fixing seat. The cell internal resistance detector is convenient to operate, and the measuring accuracy is high.
Description
Technical field
The present invention relates to a kind of detector, relate 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, and 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 detection frock; Its objective is and improve detection speed and work efficiency, the technical scheme that for this reason adopts is: the positive and negative sheet metal corresponding with battery plus-negative plate to be detected position is set in the frock housing, should be connected with voltage internal resistance table through lead by positive and negative sheet metal.During use, battery to be detected directly is placed in the frock housing can shows internal resistance of cell reading, though 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 matters to be solved by this invention 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 present invention adopted is: a kind of internal resistance of cell detector; Comprise base; The probe stationary seat is installed on the said base; Said probe stationary seat comprises left probe stationary seat and right probe stationary seat, being equipped with and the contacted a plurality of probes of the electrode of tested battery in opposite directions on said left probe stationary seat and the said right probe stationary seat, and said a plurality of probes evenly are spaced and dismountable being installed on said left probe stationary seat and the said right probe stationary seat; Dismountable on the said base tested battery mounting is installed, said tested battery mounting is positioned in the middle of said left probe stationary seat and the said right probe stationary seat.
Be connected with respectively on said left probe stationary seat and the said right probe stationary seat and drive its drive unit that on said base, slides.
Said drive unit is a cylinder.
Compared with prior art, beneficial effect of the present invention is:
1. because internal resistance of cell detector of the present invention is provided with left probe stationary seat and right probe stationary seat; Be separately installed with a plurality of probes on this left side probe stationary seat and the right probe stationary seat; And dismountable tested battery mounting is installed in the middle of left probe stationary seat and right probe stationary seat; During use, at first tested battery is fixed on the tested battery mounting through frock, the probe on left probe stationary seat and the right probe stationary seat is contacted with the electrode of tested battery respectively; The final detection of accomplishing the tested internal resistance of cell; Can not occur the phenomenon of 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 present invention be easy to operate, measuring accuracy is higher.
2. because all detachably settings of internal resistance of cell detector middle probe of the present invention 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 make its internal resistance that can be suitable for all size battery test, so the present invention uses, and dirigibility is higher, applicability is wider.
Description of drawings
Specify the present invention below in conjunction with accompanying drawing and embodiment:
Fig. 1 is a structural representation of the present invention.
Among the figure: base 10, probe stationary seat 12, tested battery mounting 14, left probe stationary seat 16, right probe stationary seat 18, probe 20.
Embodiment
As shown in Figure 1; A kind of internal resistance of cell detector of the present invention; Include base 10, probe stationary seat 12 and tested battery mounting 14; Wherein probe stationary seat 12 is installed on the base 10 with tested battery mounting 14; Probe stationary seat 12 includes on left probe stationary seat 16 and this left side probe stationary seat 16 and the right probe stationary seat 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 stationary seat 16 and the right probe stationary seat 18, and tested battery mounting 14 is dismountable to be installed on the base 10 and to be positioned in the middle of left probe stationary seat 16 and the right probe stationary seat 18, for easy to operate; On left probe stationary seat 16 and right probe stationary seat 18, be connected with respectively and drive its drive unit that on base 10, slides (for diagram), preferred drive unit is a cylinder.
During actual the use; At first tested battery is fixed on the tested battery mounting 14 through frock; Then the probe on left probe stationary seat 16 and the right probe stationary seat 18 is contacted respectively with the electrode of tested battery; The phenomenon of tested battery and probe loose contact can not appear in the final detection of accomplishing the tested internal resistance of cell in this process, do not survey or the inaccurate phenomenon of test result thereby mistake can not occur.
In sum, the present invention is not only easy to operate but also measuring accuracy is higher.
The above is merely preferred embodiments of the present invention; Protection scope of the present invention is not exceeded with above-mentioned embodiment; As long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
