[0024] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0025] A copper bar assembly for connecting a new energy battery comprises a bottom plate 1, a top plate 2 is arranged just above the top of the bottom plate 1, side baffles 3 are arranged between both sides of the bottom plate 1 and the top plate 2, and a plurality of copper bar bodies 4 are arranged side by side on the two side baffles 3 located between the bottom plate 1 and the top plate 2; splicing mechanisms 5 are respectively arranged at both ends of the two side baffles 3, and the splicing mechanisms 5 include a first rack 501, a second rack 502 and a tooth plate 503; a first rack 501 and a second rack 502 are arranged at both ends of the two side baffles 3 away from an inner groove 6, the first rack 501 and the second rack 502 are symmetrical up and down, and a tooth plate 503 is movably installed inside the inner groove 6, and the first rack 501 and the second rack 502 are meshed with the tooth plate 503;

[0026] In this embodiment, two groups of identical copper bar assemblies are spliced ​​during installation. During splicing, one end of the first group of copper bar assemblies with the first rack 501 and the second rack 502 is inserted into the two inner grooves 6 of the other group of copper bar assemblies. After the first rack 501 and the second rack 502 are inserted into the inner grooves 6, the tooth blocks on the first rack 501 and the second rack 502 are clamped and fixed with the tooth blocks on the same side of the inner groove 6. In this way, during installation, the first rack 501 and the second rack 502 can be initially positioned during the process of being inserted into the inner groove 6, so that the copper bar body 4 will not be misaligned up and down after docking.

[0027] like Figure 1 and Figure 4As shown, the two side baffles 3 are provided with inner grooves 6 on one side away from the first rack 501 and the second rack 502, and a locking mechanism 7 is provided between the inner groove 6 and the tooth plate 503, and the locking mechanism 7 includes a threaded groove 701, a spring 702 and a knob 703; the middle part of the tooth plate 503 is provided with a threaded groove 701, and the four corners of the inner wall of the inner groove 6 are provided with springs 702, and the other ends of the four springs 702 are respectively provided at the four corners of the back side of the tooth plate 503, and the middle part of the inner groove 6 close to the spring 702 is provided with a knob 703 through a bearing, and the middle part of the knob 703 is threadedly connected with the threaded groove 701, and the end of the knob 703 passes through the side baffle 3 and is located outside the side baffle 3;

[0028] When the first rack 501 and the second rack 502 are fixed to the tooth plate 503, the knob 703 is twisted. When the knob 703 rotates, it cooperates with the thread groove 701 to control the tooth plate 503 to move toward one side of the first rack 501 and the second rack 502. In this way, the first rack 501 and the second rack 502 are more tightly connected to the tooth plate 503 after being clamped, thereby avoiding falling off later. When disassembling, the knob 703 is reversed so that the tooth plate 503 will retreat from one side of the first rack 501 and the second rack 502. In this way, the first rack 501, the second rack 502 and the tooth plate 503 can be quickly unlocked, thereby achieving the purpose of facilitating quick disassembly and assembly.

[0029] like Figure 2 As shown, the surfaces of the copper busbar bodies 4 are coated with an insulating layer;

[0030] In this embodiment, the surface of the copper busbar body 4 is coated with an insulating layer to achieve the purpose of overall insulation.

[0031] like Figure 2 As shown, the outer side of the middle part of the copper busbar body 4 is covered with a heat shrink tube 8, and the heat shrink tube 8 is made of polyvinyl chloride;

[0032] In this embodiment, polyvinyl chloride has good electrical insulation performance and high temperature resistance. When covering the surface of the copper busbar or the aluminum busbar, polyvinyl chloride can provide a certain degree of insulation and protection from the external environment.

[0034] In this embodiment, the flame retardant partitions 9 provided on both sides of the side baffle 3 can play a supporting and sealing role, and can also be flame retardant.

[0035] Working principle: When installing, two identical sets of the device are spliced ​​together. When splicing, insert one end of the first set of copper bar components with the first rack 501 and the second rack 502 from the two inner grooves 6 of the other set of copper bar components. After the first rack 501 and the second rack 502 are inserted into the inner groove 6, the tooth blocks on the first rack 501 and the second rack 502 are clamped and fixed with the tooth blocks on the same side of the inner groove 6. When the first rack 501, the second rack 502 and the tooth plate 503 are clamped and fixed, turn the knob 7 03. When the knob 703 is rotated, it cooperates with the thread groove 701 to control the tooth plate 503 to move toward the side of the first rack 501 and the second rack 502, so that the first rack 501, the second rack 502 and the tooth plate 503 are more tightly connected after being engaged, thereby avoiding falling off later. When disassembling, reverse the knob 703, so that the tooth plate 503 will retreat from the side of the first rack 501 and the second rack 502, so that the first rack 501, the second rack 502 and the tooth plate 503 can be quickly unlocked.
