Abstract
The utility model discloses an insulating pad for testing a cylindrical lithium battery. The insulating pad comprises an annular insulating pad body, wherein two clamping columns matched with process holes in a positive cap are arranged at the back of the insulating pad body; elastic plug strips are arranged on two opposite side walls of each clamping column, and are vertically arranged; the cross section of each elastic plug strip is of a large semicircular shape. The insulating pad for testing the cylindrical lithium battery has the advantages that the insulating pad is independently designed; before testing, the insulating pad can be conveniently and quickly arranged on the positive cap of the cylindrical lithium battery, so that the positive cap of the cylindrical lithium battery is separated from a negative electrode, and a body led out of the positive cap is prevented from touching a negative steel shell during testing; meanwhile, the clamping columns and the elastic plug strips are arranged on the insulating pad body, so that the insulating pad body can be protected from being easily disengaged from the cylindrical lithium battery.
Description
Technical field
The utility model relates to a kind of cylindrical lithium battery test insulation cushion.
Background technology
As shown in Figure 1, the positive pole of Small Cylindrical type lithium battery 1 side of blocking a shot has at least two technology grooves 2, and negative pole is connected with whole outer box hat 3, box hat is also provided with a circle groove 4 near one end of anodal block outside, before Small Cylindrical type lithium battery dispatches from the factory, need to carry out diversified test, as: short-circuit test, overcharge test, large multiplying power loop test etc., but between negative pole box hat and anodal block only between the sealing ring of alternating floor insulation, while making to test, be easy to the block a shot nickel strap of drawing or steel band of positive pole to encounter on negative pole box hat and cause short circuit.
Utility model content
The purpose of this utility model is to provide a kind of cylindrical lithium battery test insulation cushion, can effectively solve existing cylindrical lithium battery anodal block lead body in the time of test and easily encounter the problem that causes short circuit on negative pole box hat.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of cylindrical lithium battery test insulation cushion, comprise the insulation cushion body of annular, described insulation cushion body center has and the positive pole suitable circular hole of blocking a shot, the back side of described insulation cushion body be provided with two with the suitable clamping post of anodal block fabrication hole, on two relative sidewalls of described each clamping post, be equipped with elasticity tent, described elasticity tent vertically arranges and cross section is large semi-circular.
Preferably, the outer eaves of described insulation cushion body is provided with the elastic buckles limit to downward-extension, and described elastic buckles limit is provided with the fixture block that blocks the outer box hat upper groove of cylindrical lithium battery; The further energy of insulation cushion body and negative pole box hat are formed a fixed connection, and while preventing from testing, the disengaging of insulation cushion body causes short circuit.
Compared with prior art, the utility model has the advantages that: design separately an insulation cushion, before test, can be arranged on easily and fast the positive pole block of cylindrical lithium battery, thereby positive pole block and the negative pole of cylindrical lithium battery are separated, while preventing from testing, encounter negative pole box hat from positive pole block lead body, insulation cushion body is provided with clamping post and elasticity tent simultaneously, can ensure can not depart from easily cylindrical lithium battery at insulation cushion body.

Embodiment
Consult Fig. 2, Fig. 3, Fig. 4 is the embodiment of a kind of cylindrical lithium battery test of the utility model insulation cushion, a kind of cylindrical lithium battery test insulation cushion, comprise the insulation cushion body 5 of annular, described insulation cushion body 5 centers have and the positive pole 1 suitable circular hole 6 of blocking a shot, the back side of described insulation cushion body 5 be provided with two with the suitable clamping post 7 of anodal block 1 fabrication hole 2, on two relative sidewalls of described each clamping post 7, be equipped with elasticity tent 8, described elasticity tent 8 vertically arranges and cross section is large semi-circular, the outer eaves of described insulation cushion body 5 is provided with the elastic buckles limit 9 to downward-extension, described elastic buckles limit 9 is provided with the fixture block 10 that blocks outer box hat 3 upper grooves 4 of cylindrical lithium battery.
A kind of method of testing that adopts cylindrical lithium battery test insulation cushion, by insulation cushion body 5 by 1 end of blocking a shot at the positive pole of cylindrical lithium battery, the positive pole block 1 of cylindrical lithium battery is exposed from the circular hole 6 of insulation cushion body 5, simultaneously insulation cushion body 5 all covers the block a shot negative pole box hat on 1 side of positive pole, then press insulation cushion body 5, make to clamp in the fabrication hole 2 that post 7 enters anodal block 1, elasticity tent 8 is between clamping post 7 and anodal block 1 fabrication hole 2 sidewalls, nickel strap or the steel band of burn-oning respectively test use to again the positive pole block 1 of cylindrical lithium battery and negative pole, make elasticity mouth limit touch outer box hat simultaneously, allow fixture block snap in groove.
An insulation cushion of design separately, before test, can be arranged on easily and fast the positive pole block 1 of cylindrical lithium battery, thereby positive pole block 1 and the negative pole of cylindrical lithium battery are separated, while preventing from testing, encounter negative pole box hat from positive pole 1 lead body of blocking a shot, insulation cushion body 5 is provided with clamping post 7 and elasticity tent 8 simultaneously, can ensure can not depart from easily cylindrical lithium battery at insulation cushion body 5.
The foregoing is only specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
