Abstract
The utility model belongs to work fixtures, in particular to a lithium ion battery internal resistance testing fixture, which is characterized by mainly comprising a fixture casing and an internal resistance voltmeter. A positive metal piece and a negative metal piece corresponding to a positive pole and a negative pole of a battery to be tested in positions are arranged inside the fixture casing, and the positive metal piece and the negative metal piece are connected with the internal resistance voltmeter through leads. The lithium ion battery internal resistance testing fixture is simple in structure and practical and has the advantage that a reading of the battery internal resistance can be displayed only on the premise that the battery to be tested is directly placed in the fixture casing, and accordingly testing speed and working efficiency are improved.
Description
Technical field
The utility model belongs to frock clamp, relates in particular to a kind of lithium ion battery internal resistance and detects frock.
Background technology
Need in the battery manufacture process internal resistance of battery is detected, whether qualified to estimate battery.Method at present commonly used is directly two test pencils of voltage internal resistance table to be contacted the reading of observation voltage internal resistance table with battery plus-negative plate to be detected.For detecting typical products in mass production, this mode of operation is very loaded down with trivial details, and detection speed slows down, and is unfavorable for that scale detects.If develop a kind of just battery directly can be placed in the device can real reading frock, will have great practice significance to enterprise.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of simple in structure, detects lithium ion battery internal resistance fast and detects frock.
The utility model for achieving the above object, by the following technical solutions: a kind of lithium ion battery internal resistance detects frock, it is characterized in that, mainly comprise frock housing and voltage internal resistance table, be provided with the positive and negative sheet metal corresponding with battery plus-negative plate to be detected position in the described frock housing, described positive and negative sheet metal is connected with voltage internal resistance table by lead.
Beneficial effect: battery to be detected directly is placed in the frock housing can shows internal resistance of cell reading, improved detection speed and work efficiency, simple and practical.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of lithium ion battery internal resistance detects frock, mainly comprise frock housing 1 and voltage internal resistance table 2, the frock enclosure interior is a hollow shape, any one side at the frock housing is established an opening, be responsible for the battery of packing into, the shape and the battery of frock housing are complementary, guaranteeing that battery to be detected is put between frock housing and housing can not leave the gap, be provided with the positive and negative sheet metal corresponding 3,4 in the described frock housing with battery plus-negative plate to be detected position, when battery to be detected is put into just the both positive and negative polarity of battery contact with positive and negative sheet metal.Described positive and negative sheet metal is connected with voltage internal resistance table by lead 5.During use, cut-in voltage internal resistance table is put into the frock housing with battery to be detected, with the tight mesuring battary of hand, battery plus-negative plate is contacted with positive and negative sheet metal, can show the reading of the internal resistance of cell on voltage internal resistance table, and is simple to operate, easy to use.
The above only is a 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.
