Description

TECHNICAL FIELD

[0001] The utility model relates to the field of battery module, especially point to a kind of isolating plate assembly. BACKGROUND

[0002] In the existing battery module, the isolating plate is a key component, which is used to support the electrical connection sheet (such as aluminum bar, copper bar), and to isolate the FPC assembly or wire harness from the battery cell; and the electrical connection sheet is used to connect with the pole piece of the battery cell (usually welded).

[0003] Currently, the isolating plate and the electrical connection sheet are produced separately, and then assembled together during the assembly of the battery module. The isolating plate usually has a buckle to limit the electrical connection sheet, and the position of the electrical connection sheet on the isolating plate is movable so that the electrical connection sheet can be accurately connected with the pole piece of the battery cell.

[0004] However, since the isolating plate and the electrical connection sheet are produced separately and then assembled, it affects the assembly efficiency of the battery module. In addition, during transportation, many electrical connection sheets are placed together, which makes the electrical connection sheets easily collide with each other and scratch the surface of the electrical connection sheet, and the scratches on the surface of the electrical connection sheet affect the performance of the electrical connection sheet.

[0005] In view of the above problems, it is necessary to study an isolating plate assembly which helps to improve the assembly efficiency of the battery module and avoid scratches on the electrical connection sheet during transportation of the isolating plate assembly. SUMMARY

[0006] The purpose of the utility model is to provide an isolating plate assembly which helps to improve the assembly efficiency of the battery module and avoid scratches on the electrical connection sheet during transportation of the isolating plate assembly.

[0007] To achieve the above purpose, the solution of the utility model is as follows:

[0008] An isolating plate assembly includes an isolating plate and a plurality of electrical connection sheets. The isolating plate is combined with each electrical connection sheet by encapsulation. The isolating plate is provided with a fitting hole corresponding to each electrical connection sheet. Each electrical connection sheet is accommodated in each fitting hole. At least one elastic arm connected with the electrical connection sheet is arranged in each fitting hole.

[0009] Each fitting hole of the isolating plate is arranged in an array.

[0010] Four elastic arms are arranged in the fitting hole. Two of the four elastic arms in the fitting hole are connected with two ends of the same side of the electrical connection sheet, respectively. The other two of the four elastic arms in the fitting hole are connected with two ends of the other side of the electrical connection sheet, respectively.

[0011] The electric connecting piece is provided with a connecting part for connecting the elastic arm, the connecting part comprises a first opening and a second opening intersecting with each other, the first opening penetrates the side edge of the electric connecting piece; the elastic arm has a connecting head matching the connecting part.

[0012] The connecting sleeve is arranged in the matching hole, the elastic arm is connected with the electric connecting piece through the connecting sleeve, one end of the elastic arm is connected with the inner wall of the matching hole, and the other end of the elastic arm is connected with the connecting sleeve; each connecting sleeve is connected with at least one elastic arm, and the connecting sleeve at least covers the circumferential edge of one end of the electric connecting piece.

[0013] The matching hole is provided with four elastic arms and two connecting sleeves, two elastic arms of the four elastic arms in the matching hole are connected with two sides of one of the two connecting sleeves respectively, and the other two elastic arms of the four elastic arms in the matching hole are connected with two sides of the other one of the two connecting sleeves respectively; the two connecting sleeves cover the circumferential edges of two ends of the electric connecting piece respectively.

[0014] The elastic arm has at least two bending parts.

[0015] The elastic arm comprises a first connecting strip, a second connecting strip and a third connecting strip arranged integrally, the first end of the first connecting strip is integrally connected with the inner wall of the matching hole, the second end of the first connecting strip is connected with the first end of the second connecting strip in a bending manner, the second end of the second connecting strip is connected with the first end of the third connecting strip in a bending manner, and the second end of the third connecting strip is connected with the electric connecting piece.

[0016] The length of the second connecting strip of the elastic arm is greater than the lengths of the first connecting strip and the second connecting strip, and the second connecting strip is parallel to the side edge of the electric connecting piece.

[0017] The elastic arm comprises a first connecting strip, a second connecting strip, a third connecting strip, a fourth connecting strip and a fifth connecting strip arranged integrally, the first end of the first connecting strip is integrally connected with the inner wall of the matching hole, the second end of the first connecting strip is connected with the first end of the second connecting strip in a bending manner, the second end of the second connecting strip is connected with the first end of the third connecting strip in a bending manner, the second end of the third connecting strip is connected with the first end of the fourth connecting strip in a bending manner, the second end of the fourth connecting strip is connected with the first end of the fifth connecting strip in a bending manner, and the second end of the fifth connecting strip is connected with the electric connecting piece.

[0018] The second connecting strip and the fourth connecting strip of the elastic arm are parallel to the side edge of the electric connecting piece.

[0019] By adopting the above solution, this utility model forms a separator assembly by bonding the separator plate and each electrical connector piece with adhesive. This arrangement allows the electrical connector pieces to be directly fitted onto the separator plate after manufacturing, ensuring a stable fit. During subsequent transportation of the separator assembly, the electrical connector pieces are transported along with the separator plate. During transportation, the electrical connector pieces of each separator assembly remain relatively stable, preventing scratches caused by collisions between different electrical connector pieces. Furthermore, since the electrical connector pieces are directly fitted onto the separator plate after manufacturing, subsequent battery module assembly eliminates the need for separate assembly of the electrical connector pieces and the separator plate, thus improving battery module assembly efficiency. Additionally, the elastic arm's deformability allows the electrical connector pieces to move relative to the separator plate under the force applied by the assembly personnel, ensuring accurate alignment of the electrical connector pieces with the cell's electrode plates.
