The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned technology; And a kind of connection row and battery cover of dynamic lithium battery are provided; The fastening method of attachment that combines with welding of nut is adopted in the connection of each piece battery of battery pack; Guarantee battery terminal and the steadiness and the validity that are connected row, thereby improve the big multiplying power discharging property of battery.
The utility model is for realizing above-mentioned purpose; Adopt following technical scheme: a kind of connection row and battery cover of dynamic lithium battery, comprise the battery cover that connects row and have explosion-proof valve, it is characterized in that: said connection row is lamellar; Its rectangle thin plate bilateral symmetry is provided with the welding ear; And be connected row and connect and to be whole " worker " font, said welding ear is provided with detent, said connection arranges vertically that center line is arranged with the pole via hole.
Said connection row radial center line position is provided with the circular arc circular arch that is flexible coupling.
Said detent quantity is five, wherein up and down each two, and middle one.
Said battery cover comprises battery cover board, positive and negative terminals, upper-lower seal space washer, plane terminal and connects leader; Affixed positive and negative terminals on the said battery cover board; Said positive and negative terminals passes circular hole on the battery cover board, the affixed order of positive and negative terminals be respectively be connected with in turn from bottom to top connect leader, lower seal space washer, battery cover board, on seal space washer and plane terminal.
Said battery cover positive terminal material is brass nickel plating, and battery cover negative terminal material is red copper nickel plating, and both positive and negative polarity plane terminal material is a nickel, and the plane terminal is shaped as rectangle.
Beneficial effect: the fastening and connected mode that combines of welding through the nut of above-mentioned connection row and battery cover has guaranteed battery terminal and has been connected the steadiness of arranging connection; Battery terminal and the contact area that is connected row have been increased; Having increased the high-power of battery discharges and recharges and security performance; Improve the reliability of assembling and welding performance, be fit to large-scale industrial production.
