Thus, the positive electrode plate 11 and the negative electrode plate 12 are insulated by the insulating separator 13, and breakdown and electric leakage between the positive electrode plate 11 and the negative electrode plate 12 are effectively prevented; the positive electrode plate 11 is clamped between the insulating separator 13 and the second insulating baffle 15, and current is prevented from being broken through from two side faces of the positive electrode plate 11; the negative electrode plate 12 is sandwiched between the insulating separator 13 and the first insulating barrier 14, and prevents current from breaking through from both sides of the negative electrode plate 12.

Alternatively, in one embodiment, the positive electrode plate 11 and the negative electrode plate 12 are each copper plates. Thus, the copper plate has good conductivity. Optionally, in an embodiment, the bus bar operating voltage is: 4500V AC, operating current 500A.

Further, referring to fig. 1 to 5, as an embodiment of the busbar provided by the present invention, a first insulating barrier 14 is adhered to the negative electrode plate 12 by an insulating adhesive; and/or the second insulating barrier 15 is bonded to the positive electrode plate 11 by insulating glue.

Thus, the epoxy resin has better insulativity, strength and heat resistance; GPO-3 has good electrical property under high humidity, good mechanical property under medium temperature, flame retardance, electric arc resistance and electric leakage trace resistance.

Further, referring to fig. 1 to 5, as an embodiment of the busbar provided by the present invention, the busbar further includes a positive output terminal 21 and a negative output terminal 22; the first insulating baffle 14 is provided with a first insulating strip 141, and the positive output end 21 is arranged on the first insulating strip 141; the first insulating baffle 14 is provided with a second insulating strip 142, and the negative output end 22 is arranged on the second insulating strip 142; a third insulating strip 152 is disposed on the second insulating barrier 15 between the first insulating strip 141 and the second insulating strip 142. Thus, on the first insulating barrier 14, the positive output terminal 21 is insulated from the outside by the first insulating strip 141, and the negative output terminal 22 is insulated from the outside by the second insulating strip 142; on the second insulating barrier 15, a third insulating strip 152 separates the positive output terminal 21 and the negative output terminal 22 to prevent leakage.

Specifically, in one embodiment, the positive output end 21 and the negative output end 22 have different heights (height: based on the outer surface of the first insulating barrier 14), which increases the creepage distance between the positive output end 21 and the negative output end 22. Specifically, in an embodiment, through holes for the positive output end 21 and the negative output end 22 to pass through are formed in the positive electrode plate 11 and the negative electrode plate 12 (through holes corresponding to the positive output end 21 and the negative output end 22 one to one are formed in the positive electrode plate 11, and through holes corresponding to the positive output end 21 and the negative output end 22 one to one are formed in the negative electrode plate 12), the positive output end 21 is insulated from the positive electrode plate 11 and the negative electrode plate 12 by an insulating ring (the insulating ring is clamped in the through holes), and the negative output end 22 is insulated from the positive electrode plate 11 and the negative electrode plate 12 by the insulating ring (the insulating ring is clamped in the through holes), so that electric leakage is avoided.

Therefore, the T-shaped insulating strip is easy to produce, and the top surface (the top surface, when the cross section of the fourth insulating strip 151 is placed in the T shape, the top end surface of the T shape is the top surface) of the T shape is abutted against the second insulating baffle 15, so that the two sides of the fourth insulating strip 151 on the second insulating baffle 15 can be separated; the principle of the fifth insulating strip is the same.

Further, referring to fig. 1 to 5, as an embodiment of the bus bar provided by the present invention, the third insulating strip 152 and the fourth insulating strip 151 respectively extend in a linear direction and are disposed perpendicular to each other, and/or the third insulating strip 152 and the fifth insulating strip respectively extend in a linear direction and are disposed perpendicular to each other. Therefore, the third insulating strips 152 and the fourth insulating strips 151 can be mutually supported, so that the deformation of the third insulating strips 152/the fourth insulating strips 151 under the action of external force is reduced; similarly, the third insulating strip 152 and the fifth insulating strip can be supported by each other, and the deformation of the third insulating strip 152/the fifth insulating strip under the external force is reduced.

Further, referring to fig. 1 to 5, as an embodiment of the busbar according to the present invention, a groove is formed by surrounding an edge of the first insulating barrier 14 and an edge of the second insulating barrier 15, and the groove is filled with an insulating glue. In this way, the first insulating barrier 14 and the second insulating barrier 15 enclose the positive electrode plate 11 and the negative electrode plate 12 in the gap between the first insulating barrier 14 and the second insulating barrier 15 by the insulating paste.

Optionally, in an embodiment, the insulating adhesive is a hot melt adhesive. Specifically, in one embodiment, the hot melt adhesive is an EVA (EVA: ethylene-vinyl acetate copolymer) adhesive.
