Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1, it is a schematic structural diagram of the novel laminated busbar provided by the present invention. The novel laminated busbar comprises a first L-shaped polar plate 10, a second L-shaped polar plate 20 arranged on one side of the first L-shaped polar plate 10, a third L-shaped polar plate 30 arranged on one side of the second L-shaped polar plate 20, and a plurality of copper columns 40 arranged in the first L-shaped polar plate 10, the second L-shaped polar plate 20 and the third L-shaped polar plate 30. It is conceivable that the novel laminated busbar further includes other functional modules, such as a tag module, a component module, and the like, which are known to those skilled in the art and will not be described herein.

The first L-shaped polar plate 10, the second L-shaped polar plate 20 and the third L-shaped polar plate 30 are bonded together by glue.

Please refer to fig. 2. First L type polar plate 10 includes an L type plate body 11, four intervals set up in lap-joint zone 12 on the long side of L type plate body 11, four intervals set up in first on the short side of L type plate body 11 connects and draws terminal 13 to and two insulating films 14 that set up on L type plate body 11 that show.

The lap joint zone 12 can be directly connected with the component modules, the first leading terminal 13 can also be directly connected with the components of the module, so that the copper bar switching is omitted, and the current can be uniformly transmitted to each component module.

The lap zone 12 includes a first connection hole 121, two first avoiding holes 122 located at one side of the first connection hole 121, and two insulation rings 123 filled in the two first avoiding holes 122, respectively.

The copper column 40 is arranged in the first connecting hole 121, the copper column 40 protrudes out of the surface side face of the L-shaped plate body 11 facing the second L-shaped polar plate 20, so that when the second L-shaped polar plate 20 is arranged, the partially protruding copper column 40 extends into the second L-shaped polar plate 20, overlaps the two polar plates and improves the structural strength between the two polar plates.

The axle center and two of first connecting hole 121 the axle center of first dodging hole 122 is equilateral triangle and distributes, these limit triangle-shaped structures with second L type polar plate 20 and third L type polar plate 30 cooperate, make components and parts setting be in back on the overlap joint zone 12, can guarantee that novel female the arranging atress of stromatolite is even, further improves the female structural strength who arranges of this stromatolite. The specific matching will be explained below.

The insulating ring 123 in the first avoidance hole 122 can insulate the first L-shaped polar plate 10 and the second L-shaped polar plate 20, and reinforces the novel laminated busbar structure, and simultaneously improves the electrical insulation of the laminated busbar.

Two side surfaces of the first L-shaped plate 10 are covered with insulating films 14 for insulating from other plates, thus ensuring the electrical insulation of the first L-shaped plate 10. It is conceivable that a plurality of through holes for avoiding the bridging region 12 should be provided in the insulating film 14.

The second L-shaped plate 20 and the third L-shaped plate 30 have a structure similar to that of the first L-shaped plate 10. There are also four landing zones, four lead terminals, and two insulating films, but the first connection holes 121 and the first escape holes 122 in the landing zones are staggered in position.

Four second leading terminals 21 which are long strips are arranged on the short side edge of the second L-shaped polar plate 20 at intervals, and the second leading terminals 21 and the first leading terminals 13 are arranged in a staggered mode. Four third lead terminals 31 are disposed at intervals on short sides of the third L-shaped plate 30, and the third lead terminals 31 are disposed in a staggered manner with respect to the first lead terminals 13 and the second lead terminals 21.
