Detailed description of the invention
As shown in figs. 1-4, a kind of big current polymer battery clamp 1, comprises base 2 and the pole piece under being located at base, and pole piece comprises a pair side pole sheet 31 and at least one middle pole piece 32, and middle pole piece 32 is positioned at the centre of a pair side pole sheet 31.
The top of a pair side pole sheet 31 is provided with the kink 33 of outwards bending.The design of side pole sheet top kink, can increase the contact area of pole piece and battery pole ear, reduces contact resistance, ensures the good contact of fixture and battery pole ear;
The kink 33 of a pair side pole sheet 31 is mutually concordant with the top of middle pole piece 32.Such design, can allow the kink of side pole sheet contact with the lug of battery with the top of middle pole piece simultaneously, increase the contact area of pole piece and battery pole ear.
The lower surface of the kink 33 of a pair side pole sheet 31 is provided with multiple contact 34, and the top of middle pole piece 32 is also provided with multiple contact 34.
Multiple contact 34 adopts annular knurl mode to make.Contact 34 on the lower surface of side pole sheet 31 and middle pole piece 32 top, adopts annular knurl mode to make, can increase the contact area of the lug 51 of pole piece and battery to be detected 5 further, more easily make the lug 51 of battery 5 clamp.
Base 2 is plastic feet, and plastic feet has locating dowel 21 and installing hole 22.
The base 2 of fixture 1 is adopted made of plastic, makes the cost of manufacture of fixture 1 low, and the design of installing hole 21 and locating dowel 22 on fixture 1 base 2, is convenient to the installation of fixture 1 on equipment.
Big current polymer battery clamp 1 in the present embodiment is installed as shown in Figure 5, fixture 1 is fixed on installing plate 4 by locating dowel 21 and installing hole 22, driven by cylinder or other external force, promotion fixture 1 compresses to the lug 51 of battery 5, realizes the clamping of the lug 51 of battery 5.
Big current polymer battery clamp in the utility model, is specially adapted to automation, the test of big current poly-lithium battery.Comprise: plastic feet easy for installation; Newly-designed side pole sheet; Newly-designed middle pole piece.Whole fixture can be arranged on equipment by plastic feet easily.The bending design enlarge active surface of both sides pole piece, significantly reduces contact resistance, ensures fixture and battery pole piece reliable contacts.The appropriate design of middle pole piece, can adjust pole piece quantity according to size of current.By the redesign of pole piece, increase the contact area of pole piece and battery, guarantee to contact well with great current cell lug.Thus ensure that precision and the reliability of battery detection equipment charging and discharging currents, voltage.In addition, this fixture is easy for installation, is specially adapted to automation equipment.
The above embodiment only have expressed Some Species embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.Without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
