Description

Technical Field

[0001] This utility model relates to the technical field of battery assembly accessories, and in particular to a composite aluminum sheet. Background Technology

[0002] In battery pack applications, real-time monitoring of the voltage of each individual cell is crucial to ensure stable operation and safety. Currently, a common practice is to connect multiple cells in series using connectors. Simultaneously, a separate wire needs to be led out from the connector between cells to enable real-time monitoring of the voltage of each individual cell; this wire is typically called a voltage sampling line. Existing connection solutions involve welding a connector separately to the inner wall of a groove on a composite aluminum sheet, providing a connection point for subsequent welding to the wire.

[0003] However, existing voltage sampling line connection methods have the following shortcomings in practical applications: battery packs often consist of multiple batteries connected in series / parallel, with multiple composite aluminum sheets connecting the batteries. This necessitates the individual welding of a connecting piece onto each composite aluminum sheet for connection with the wires, which undoubtedly increases the complexity of the battery assembly process. With the increase in processes, not only is more manpower required to complete these additional operations, but the time cost also increases significantly. Therefore, this application proposes a composite aluminum sheet. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a composite aluminum sheet that does not require separate welding of connecting pieces, thereby reducing labor and time costs.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A composite aluminum sheet, comprising:

[0007] An aluminum sheet body, wherein a protruding bridge is provided on the aluminum sheet body; and

[0008] A connector, comprising a clamp and a support block, wherein the clamp is disposed on the convex bridge and the support block is disposed on the clamp, and there is an angle between the clamp and the support block, wherein when the clamp is subjected to external force, the clamp and the support block together clamp the wire.

[0009] Optionally, both the convex bridge and the clamping piece are U-shaped structures.

[0010] Optionally, a clearance groove is provided between the clip and the convex bridge.

[0011] Optionally, the connector further includes a plurality of toothed blocks, each of which is disposed on opposite sides of the clamping piece.

[0012] Optionally, the support block is provided with an arc-shaped portion, which is located at the end of the support block away from the clamping piece.

[0013] Compared with the prior art, the present invention has at least the following advantages:

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0025] like Figures 1 to 3 As shown, in one embodiment, a composite aluminum sheet 1 includes an aluminum sheet body 10 and a connector. The aluminum sheet body 10 is provided with a protruding bridge 11. The connector includes a clamping piece 20 and a support block 30. The clamping piece 20 is disposed on the protruding bridge 11, and the support block 30 is disposed on the clamping piece 20. There is an angle between the clamping piece 20 and the support block 30. When the clamping piece 20 is squeezed by an external force, the clamping piece 20 and the support block 30 together clamp the wire.

[0026] It should be noted that both the bridge 11 and the clamping piece 20 are U-shaped structures, and both are integrally stamped with the aluminum sheet body 10. The bridge 11 is located in the middle of the aluminum sheet body 10, causing it to protrude relative to the middle position of the aluminum sheet body 10. One end of the clamping piece 20 is located on the end face of the bridge 11, and two clearance grooves 110 are formed between one end of the clamping piece 20 and the end face of the bridge 11. The two clearance grooves 110 are located at both ends of the end face of the clamping piece 20 / the end face of the bridge 11, so that the middle position of the end face of the clamping piece 20 is connected to the middle position of the end face of the bridge 11. Thus, when the assembler presses the two sides of the clamping piece 20 with a tool, such as pliers, the two inner sidewalls of the clamping piece 20 will come closer together to clamp the wire. Furthermore, the support block 30 is disposed on any end of the clamping piece 20 away from the protrusion 11, and the angle between the support block 30 and the clamping piece 20 is 90 degrees. An arc-shaped portion 31 is provided on the end of the support block 30 away from the clamping piece 20, and the extension direction of the arc-shaped portion 31 is close to the inner bottom wall of the clamping piece 20. When the clamping pieces 20 clamp the wire together, one side of the clamping piece 20 will drive the support block 30 to abut against the inner side wall of the other side. Since the arc-shaped portion 31 is provided on the end of the support block 30 away from the clamping piece 20, and the extension direction of the arc-shaped portion 31 is close to the inner bottom wall of the clamping piece 20, when the arc-shaped portion 31 abuts against the inner side wall of the other side of the clamping piece 20, the arc-shaped portion 31 will slide along the inner side wall towards the inner bottom wall of the clamping piece 20, so that the angle between the support block 30 and the inner side wall of the clamping piece 20 gradually decreases, thereby causing the support block 30 to move obliquely from the end of the clamping piece 20 towards the inner bottom wall of the clamping piece 20. In this way, when the two sides of the clip 20 come closer to each other, the arc-shaped part 31 of the support block 30 moves closer to the inner bottom wall of the clip 20, so that the two sides of the clip 20 and the support block 30 together surround and clamp the wire, thereby preventing the wire from slipping out from the opening between the two ends of the clip 20.

[0027] like Figures 1 to 3 As shown, in one embodiment, the connector further includes a plurality of toothed blocks 40, each toothed block 40 being disposed on opposite sides of the clamping piece 20.

[0028] It should be noted that the clamp 20 has a U-shaped structure, with each toothed block 40 disposed on the two opposing inner sidewalls of the clamp 20, so that each toothed block 40 faces each other. When the two sides of the clamp 20 approach each other to clamp the wire, the two sides of the clamp 20 simultaneously drive each toothed block 40 to approach and engage with each other to clamp the wire. Specifically, existing wires are usually made of multiple thin wires twisted together. When the insulation shell is removed from the ends of the wires, the multiple thin wires will be in a scattered state. When the toothed blocks 40 on both sides of the clamp 20 engage with each other, each toothed block 40 bites into the scattered thin wires, increasing the contact area between the wire and the connector, thereby increasing the force that the wire can withstand when pulled, thus increasing the connection stability between the wire and the connector.

[0029] It should be noted that when one end of the wire is inserted into the middle position of the clamp 20, the assembler can quickly clamp the wire with a tool. This reduces the need to weld a separate connecting piece for connecting the wire onto the aluminum sheet body 10, effectively reducing labor and time costs.

[0030] In one embodiment, two connectors are provided, each with a protrusion on one end face of the bridge 11. This allows the installer to choose different directions for connection according to the actual installation requirements on site, thus providing convenience for installation.

[0031] In one embodiment, the convex bridge 11, clamping piece 20, support block 30, arc-shaped part 31 and several toothed blocks 40 are all integrally stamped and formed with the aluminum sheet body 10, so that the composite aluminum sheet 1 of this application does not need to provide additional parts for welding, thereby reducing the material cost of production.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
