Description

Technical Field

[0001] This utility model belongs to the field of integrated busbar technology, specifically relating to an integrated busbar using a wire harness-type acquisition component. Background Technology

[0002] In existing integrated busbars, FPC type integrated busbars can form fuses by controlling the line width during circuit printing. FFC type integrated busbars, because their copper wires are flat, can also have fuses punched out on the copper wires. Unlike these two types of integrated busbars, most existing wire harness type integrated busbars do not have fuses installed on the lines. When the circuit experiences abnormal conditions such as short circuits or overloads, it is easy to damage the equipment and cause safety issues. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated busbar that uses a wire harness-type acquisition component.

[0004] To achieve the above objectives, this utility model discloses an integrated busbar using a wire harness-type acquisition component, comprising a bracket, a wire harness, multiple busbar components, multiple conductive connecting pieces, and multiple PCB boards;

[0005] The plurality of busbars are mounted on the bracket, and each busbar is provided with a conductive connecting piece, one end of which is connected to the busbar;

[0006] Each PCB board has a first line, one end of which is connected to the other end of a conductive connector.

[0007] The wiring harness is mounted on the bracket, and the wiring harness includes multiple first acquisition lines, with each first acquisition line connected to one of the first lines.

[0008] A fuse is formed in a portion of the first circuit.

[0009] Preferably, the circuit includes a first conductive wire, a fuse, and a second conductive wire connected in sequence, the first conductive wire being connected to a conductive connecting piece, and the second conductive wire being connected to a first acquisition wire;

[0010] The line widths of the first and second conductive wires are greater than the line width of the fuse.

[0011] Preferably, the first circuit is formed on the PCB board through an etching process.

[0012] Preferably, the first acquisition line is welded and fixed to the first line.

[0013] Preferably, the welding positions of the first acquisition line and the first line are coated with protective adhesive.

[0014] Preferably, the PCB board has multiple first lines, and one end of each of the multiple first lines is connected to a conductive connecting piece.

[0015] Preferably, at least a portion of the PCB board has a second circuit, one end of which is connected to a temperature sensor;

[0016] The harness also includes a second acquisition line, which is connected to the other end of the second line.

[0017] Preferably, there are multiple second lines.

[0018] Preferably, the conductive connecting piece is fixed to the busbar by laser welding.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] Multiple PCBs are set on the wire harness type integrated busbar. The PCBs serve as adapters to connect the conductive connecting pieces and the acquisition lines. A fuse is formed in part of the first line of the PCB. In this way, when the current is too large or overload occurs, the fuse blows, the acquisition signal is interrupted, and the battery can report an error and stop working after the control system collects the abnormal signal, thus ensuring the safe use of the battery module.

[0021] The PCB board is a circuit structure with an integrated fuse. In actual use, it is a standard component, highly versatile, and applicable to different product models. Furthermore, although the PCB board is a separate structure, it can be removed and replaced individually if damaged, preventing the entire integrated busbar from being scrapped, thus reducing maintenance costs.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] An integrated busbar employing a type 20 wire harness acquisition component, see [link / reference]. Figures 1-2The system includes a bracket 10, a wiring harness 20, multiple busbars 30, multiple conductive connecting pieces 40, and multiple PCB boards 50. The busbars 30 are aluminum alloys, and multiple busbars 30 are mounted on the bracket 10. Each busbar 30 has a conductive connecting piece 40, one end of which is fixed to the busbar 30 by laser welding. Each PCB board 50 has a first circuit 51, and the other end of the conductive connecting piece 40 is welded to one end of the first circuit 51. The wiring harness 20 is mounted on the bracket 10 and includes multiple first acquisition lines 21, each first acquisition line 21 connected to a first circuit 51.

[0027] This embodiment provides an assembly method for the above-mentioned integrated busbar: First, the conductive connecting piece 40 is soldered to the PCB board 50, and the conductive connecting piece 40 is connected to the first line 51; then, the nickel sheet with the PCB board 50 soldered on it is soldered and fixed to the busbar 30, and then the busbar 30 is fixed to the bracket 10; finally, the acquisition line is soldered and fixed to the PCB board 50, so that the acquisition line is connected to the first line 51.

[0028] In this embodiment, a fuse 53 is partially formed in the first circuit 51. Thus, in the event of excessive current or overload, the fuse 53 blows, interrupting the signal acquisition. The battery control system, upon receiving the abnormal signal, can report an error and stop operating, ensuring the safe use of the battery module. The PCB board 50 is a circuit structure with the fuse 53. In actual use, it is a standard component, highly versatile, and applicable to different product models. Furthermore, while the PCB board 50 is a separate structure, it can be removed and replaced individually if damaged, preventing the entire integrated busbar from being scrapped, thus reducing maintenance costs.

[0029] Preferably, the circuit includes a first conductive wire 52, a fuse 53, and a second conductive wire 54 connected in sequence. The first conductive wire 52 is connected to the conductive connecting piece 40, and the second conductive wire 54 is connected to the first acquisition line 21. The line width of the first conductive wire 52 and the second conductive wire 54 is greater than the line width of the fuse 53, which facilitates the welding between the first conductive wire 52 and the conductive connecting piece 40, and between the second conductive wire 54 and the first acquisition line 21.

[0030] In this embodiment, the PCB board 50 forms the first line 51 described above through an etching process.

[0031] In this embodiment, the welding positions of the first acquisition line 21 and the first line 51 are coated with protective adhesive 55, which can seal and protect the welding positions and prevent the exposed wires from being oxidized, thus affecting the detection effect.

[0032] In this embodiment, the PCB board 50 is provided with multiple first lines 51, one end of each of the multiple first lines 51 is connected to the conductive connecting piece 40. In this way, when the fuse 53 of one line blows, the acquisition line can be removed and then connected to another first line 51, so that the PCB board 50 does not need to be replaced, thus reducing maintenance costs.

[0033] In this embodiment, at least a portion of the PCB board 50 is provided with a second line 56, one end of which is connected to a temperature sensor. The wiring harness 20 also includes a second acquisition line 22, which is connected to the other end of the second line 56.

[0034] Among them, the preferred option is that there are multiple second lines, numbered 56.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
