In the present embodiment, each bus bar connector 30 is made of an aluminum-based metal material, and the electrode 201 of the plurality of cells 200 is made of aluminum, so that the bus bar connectors 30 and the electrodes 201 are made of the same metal material and are easily welded, and there is no problem that the welding melting points of different metals are different and welding is difficult. Furthermore, referring to fig. 9 and 10, when each of the converging connectors 30 is disposed on each of the converging connector carrying units 1, the limiting protrusion 161 of the converging connector carrying unit 1 passes through the corresponding slit 35 of the converging connector 30 to limit the position of the converging connector 30; the upper limiting piece 17 of the confluence connecting piece bearing unit 1 is used for limiting the uplifting stroke of the corresponding confluence connecting piece 30; the two lower limiting members 18 are used for limiting the pressing stroke of the corresponding bus bar connector 30 to prevent the corresponding battery 200 from being pressed excessively.
In the assembly process of the present embodiment, after the bus connectors 30 are disposed in the tray 10, the circuit board 50 is mounted on the tray 10, and the conductive connectors 52 of the circuit board 50 are electrically connected to the separating portions 32 of the bus connectors 30, respectively. It should be noted that, in each of the bus bar connectors 30 of the present embodiment, the separating portion 32 and the two electrode connecting portions 31 are separated from each other by the second buffer section 34 and the slit 35, respectively, to form a relatively independent board portion, and when the circuit board 50 is mounted on the separating portion 32 by the conductive connecting members 52, the influence on the conductive connecting members 52 caused by the displacement and deformation of the two electrode connecting portions 31 during the process can be greatly reduced.
Referring to fig. 8, each of the output electrode elements 40 includes an electrode connection portion 41, a lead portion 42, and a pad 43. The lead portion 42 extends outward from the electrode connecting portion 41 and serves as an external wire or conductor to conduct current. Referring to fig. 2 and 3, each of the output electrode members 40 is disposed in the corresponding output electrode member supporting unit 2 of the carrier tray 10 and electrically connected to the outermost battery 200, in this embodiment, the electrode connecting portion 41 is made of copper, and the welding pad 43 is made of aluminum and has a circular shape, so that the electrode connecting portion 41 can be welded to the electrode 201 of the outermost battery 200 via the welding pad 43, thereby overcoming the problems of different welding melting points and difficulty in welding of dissimilar metals. Since the two outermost output electrode members 40 are used for conducting current, the material thereof is mainly copper to provide good conductivity, and the two outermost output electrode members 40 respectively lead out the positive electrode and the negative electrode.
To sum up, the battery device of the present invention is composed of a plurality of bus connector carrying units 1 and two output electrode carrying units 2 through the carrying tray 10, and the carrying tray 10 is connected into a whole by the lateral buckling structure 11 and the opposite buckling structure 12 between the bus connector carrying units 1, so that the length of the carrying tray 10 can be flexibly changed by the number of the bus connector carrying units 1, and the number of the bus connectors 30 can be synchronously increased or decreased to meet the specification of the battery 200; furthermore, the assembly process of the boat 10 is simple, and the assembled boat 10 is not only safe and reliable, but also sturdy and durable. More importantly, since the plurality of bus bar connector bearing units 1 are the same, the cost of the mold and the manufacturing production can be greatly reduced, and the standard modularized mass production is realized, so that the purpose of the invention can be really achieved.
However, the above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the contents of the specification of the present invention are still included in the scope covered by the claims of the present invention.
