Description

Technical Field

[0001] The utility model relates to the technical field of separator plates, and particularly relates to a novel integrated busbar structure for battery cells. Background Art

[0002] The separator plate is an indispensable core component on power batteries, which often affects the reliability and safety of products. After wiring on the top of the separator plate of existing power batteries, it is generally not bound or bound by cable ties. After being bound by cable ties, when it is necessary to pull one or several wire harnesses for adjustment, it cannot be pulled and adjusted, and it is necessary to disassemble the cable ties before adjustment, which is very inconvenient; in addition, after the power battery is assembled, it needs to be installed in the battery pack housing, and then the cover plate is installed for encapsulation. Since the wire harness on the top of the separator plate is exposed on its top, when there is a problem with the power battery and the cover plate needs to be disassembled, the wire harness may be scratched, hung up or broken during the process of disassembling the cover plate, resulting in an increase in maintenance problems and more time-consuming maintenance. Content of the Utility Model

[0003] In order to overcome the existing technical defects, the purpose of the utility model is to provide a novel integrated busbar structure for battery cells to solve at least one of the above technical problems.

[0004] The technical solutions adopted by the utility model to solve the technical problems are as follows:

[0005] According to one aspect of the utility model, a novel integrated busbar structure for battery cells is designed, including: a separator plate and a protection plate. At least one row of buckle assemblies for movably installing wire harnesses is arranged on the separator plate, and the protection plate is detachably connected to the top of the separator plate for covering the wire harnesses arranged on the separator plate.

[0006] By adopting the above technical solutions, the buckle assemblies are arranged on the separator plate to flexibly and movably install the wire harnesses. After the wire harnesses are installed on the separator plate, the wire harnesses can be pulled and adjusted, solving the technical problem that the wire harnesses on the existing separator plate cannot be pulled and adjusted after being bound by cable ties; by detachably arranging the protection plate for covering the wire harnesses on the separator plate, the wire harnesses on the separator plate can be protected from being scratched, hung up or broken during the process of disassembling the cover plate.

[0007] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0008] In some embodiments, two rows of the buckle assemblies are arranged on the separator plate, and avoidance through holes corresponding to the leakage guiding holes on the separator plate are arranged on the protection plate.

[0009] In some embodiments, the buckle component includes two fasteners, each of which has an L-shaped structure. The two fasteners in each buckle component are staggered left and right and arranged in a rotationally symmetric structure, and a wire harness channel is formed between the two fasteners.

[0010] In some embodiments, the guard plate is snap-fitted with the isolation plate.

[0011] In some embodiments, the guard plate is connected to the isolation plate by screws.

[0012] In some embodiments, multiple groups of first buckles for snap-fitting with the edge of the guard plate are horizontally arranged on the isolation plate, and a support protrusion for supporting the guard plate is arranged below one side of each first buckle.

[0013] In some embodiments, multiple groups of second buckles for snap-fitting with the edge of the avoidance through-hole are horizontally arranged on the isolation plate.

[0014] In some embodiments, the thickness of the guard plate is 3 - 5 mm, and an avoidance notch for avoiding the buckle component is arranged thereon. Thus, the requirement for the thinness and lightness of the guard plate can be achieved.

[0015] In some embodiments, at least one end of the front and rear ends of the isolation plate is provided with a row of card-loading components for card-loading aluminum bars.

[0016] In some embodiments, there are two isolation plates, and the guard plates are respectively detachably connected to the two isolation plates, and the two isolation plates are connected by a connecting portion. Thus, a double-row isolation plate structure can be formed to meet the use requirements of large power batteries. BRIEF DESCRIPTION OF THE DRAWINGS
