Abstract
The utility model relates to an external battery current-carrying piece, which comprises a copper piece and at least one nickel piece for being connected with a battery core, wherein the nickel pieces are connected onto the copper piece in a composited manner. The external battery current-carrying piece not only has fine heat conductivity and electric conductivity, but also has the advantage of low cost.
Description
Technical field
The utility model relates to field of batteries, especially relates to a kind of outside batteries current carrying lug.
Background technology
The outside batteries current carrying lug is to be used in the battery pack a plurality of battery battery cores are carried out the device that connection in series-parallel is electrically connected, and it works to compile electric current and guide current.Existing outside batteries current carrying lug normally is made of pure nickel, because nickel has weld strength height, characteristics such as corrosion-resistant.But the resistivity of nickel itself is very big, be 70 times of copper, in the energy resource system of new forms of energy vehicular energy system and high current charge-discharge, owing to be under high magnification, the high current charge-discharge situation, the current carrying lug heating of pure nickel can be very high, causes the efficient of energy resource system self to reduce, simultaneously owing to heating increases, cause temperature rise to improve, internal refrigeration storage requires to improve.Therefore, seek a kind of weld strength with nickel metal, characteristics such as corrosion-resistant, and the outside batteries current carrying lug that possesses the advantage of low resistance is to need the problem that solves at present.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and the outside batteries current carrying lug of a kind of low internal resistance, high battery operated efficient is provided.
For achieving the above object, the utility model has adopted following technical scheme:
The utility model discloses a kind of outside batteries current carrying lug, this current carrying lug comprises copper sheet, and at least one is used to connect the nickel sheet of battery battery core, and the nickel sheet is compound to be connected on the described copper sheet.
Preferably, the nickel sheet is soft attitude pure nickel sheet, and copper sheet is soft attitude fine copper sheet.
Comprise connecting hole and louvre on the copper sheet, the nickel sheet is welded on the connecting hole by the resistance welded mode.
Owing to adopted above technical scheme, the beneficial effect that the utility model is possessed is:
Outside batteries current carrying lug of the present utility model, with respect to the pure nickel sheet, resistance obviously reduces, outside batteries current carrying lug after compound in addition can also significantly reduce material cost, therefore, the utility model not only has good thermal conductivity and conductivity, also has advantage cheaply.
Description of drawings
The following drawings explanation is more conducive to understanding of the present utility model, and size is not to provide according to structure proportion among the figure.
Fig. 1 is an outside batteries current carrying lug structure chart;
Fig. 2 is the structure chart of nickel sheet;
Fig. 3 is the structure chart of copper sheet.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail below by embodiment.
Embodiment one:
As shown in Figure 1, be the outside batteries current carrying lug of present embodiment, this current carrying lug is made of nickel and two kinds of metals of copper.
Particularly, the outside batteries current carrying lug comprises copper sheet 2, and at least one is used to connect the nickel sheet 1 of battery battery core, nickel sheet 1 compound being connected on the copper sheet 2, and distribute according to certain spacing.
Preferably, nickel sheet 1 is the soft attitude pure nickel sheet of pure nickel band through the Mould Machining moulding, and copper sheet 2 is soft attitude fine copper sheet.Can comprise a plurality of connecting holes 4 and a plurality of louvre 3 on the copper sheet 2, each nickel sheet 1 is welded on the respective connecting 4, preferably adopts the mode of resistance welded, not only is convenient to operation, and connects stable.
As shown in Figure 2, the nickel sheet 1 of present embodiment comprises splitter box 6, support bar 7 and a plurality of salient point 5, the concave point that there are splitter box 6, support bar 7 in nickel sheet 1 back side and produce owing to salient point 5.Splitter box 6 is " worker " font structure, and its effect is to guarantee welding reliability, and the salient point 5 that " worker " font is separated is used for electric core and is weldingly connected, and electric core is formed with nickel sheet 1 be electrically connected, and its quantity can be determined according to the actual requirements.Support bar 7 forms one with nickel sheet 1, and its effect is in order to stablize the structure of splitter box 6, to prevent that splitter box 6 from caving in.
Fig. 3 comprises a plurality of connecting holes 4 and a plurality of louvre 3 for the copper sheet 2 of present embodiment, adopts copper sheet and nickel sheet compound, and its resistance is than the high slightly point of fine copper, and is more much lower than nickel, and be easy to moulding, do not influence the structural strength of outside batteries current carrying lug simultaneously.
Because the battery current carrying lug is the copper nickel compound piece, so the overall electrical resistance by its battery pack of forming has remarkable reduction, therefore battery pack has good resistivity and conductivity, and the price of copper also has remarkable reduction far below the price of nickel so produce required cost.
Above content be in conjunction with concrete execution mode to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
