[0002] A battery pack is usually composed of multiple battery cells, and the battery cells are electrically connected and signal collected by busbars and collection harnesses. In the prior art, the busbars and the collection harnesses are usually connected by welding. However, when the battery is in use, if the collection harnesses are short-circuited due to failure, maintenance is usually performed. When the damaged part is small, a remedial method can be used, that is, the insulating film on the surface of a flexible printed circuit (FPC) is scraped off with a knife, and then the two ends are welded together with lead. However, this maintenance method has the following disadvantages: first, the welded part is prone to high temperature when current passes through, thereby affecting the safety of other parts; second, the surface of the welded part has too many burrs, which are difficult to handle. Therefore, providing a reliable maintenance method for the connection between the busbar and the collection harness is an urgent problem to be solved in the battery field.

Detailed Implementation

[0029] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0030] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0031] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] In related technologies, the connection between the busbar and the data acquisition line within the battery pack is typically achieved through soldering. However, this method leads to problems when the data acquisition line malfunctions and causes a short circuit. In such cases, the insulating film on the flexible circuit board needs to be scraped off with a knife before soldering for repair. The soldered area is prone to overheating when current flows, potentially affecting the safety of other components. Furthermore, the soldered surface often exhibits excessive burrs, making it difficult to remove. Therefore, the existing connection method between the busbar and the data acquisition line results in inconvenient maintenance.

[0034] Based on the above considerations, in order to solve the technical problem that the connection method of the acquisition component in the prior art leads to inconvenient maintenance, this application provides an acquisition component, including: a bus, a connecting terminal and an acquisition harness. The bus has a first side and a second side arranged opposite to each other. The bus has a mounting hole extending from the first side to the second side inside, and the opening of the mounting hole is located on the first side. The connecting terminal is detachably installed into the mounting hole. The acquisition harness is connected to the connecting terminal.

[0035] In the technical solution of this application embodiment, the busbar and the acquisition harness are detachably connected by the connection terminal. When the acquisition harness fails, the busbar and the acquisition harness can be disconnected by the connection terminal, so that the busbar and the acquisition harness are disconnected, avoiding short circuit of the acquisition line failure from affecting other cells and protecting other cells. At the same time, the damaged acquisition harness can be replaced and then installed on the busbar by the connection terminal. No soldering is required, and maintenance is convenient.

[0036] The acquisition components of this application can be applied to power batteries, energy storage batteries, electronic devices, or mechanical devices.

[0037] The technical solutions of the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0038] Please refer to Figures 1 to 3 or Figures 6 to 8 This application provides a data acquisition component, including: a busbar 1, a connecting terminal 3, and a data acquisition harness 2. The busbar 1 has a first side 11 and a second side 12 disposed opposite to each other. The busbar 1 has a mounting hole 10 extending from the first side 11 to the second side 12 inside, and the opening of the mounting hole 10 is located on the first side 11. The connecting terminal 3 is detachably installed into the mounting hole 10. The data acquisition harness 2 is connected to the connecting terminal 3.

[0039] It can be understood that the acquisition component can be a device for acquiring sampling signals from the battery cell and transmitting these signals to the battery management system. The sampling signal can be an electrical signal characterizing the operating parameters of the battery cell, such as voltage, temperature, or internal resistance. Bus 1 is used to connect the electrode terminals of the battery cell, thereby forming a series or parallel connection between the cells. The connection terminal 3 can be a structural component for electrically connecting the acquisition harness 2 and bus 1; it can be a metal component, such as a nickel sheet. The acquisition harness 2 can be various types of cables capable of transmitting electrical signals. The first side 11 and the second side 12 can be two sides arranged opposite each other along the width direction of bus 1. The first side 11 and the second side 12 are surfaces perpendicular to the side of bus 1 used for connecting the electrode terminals. The mounting hole 10 can be a groove structure formed by recessing from the first side 11 towards the second side.

[0040] In the technical solution of this application embodiment, the busbar 1 and the acquisition harness 2 are detachably connected by the connection terminal 3. When the acquisition harness 2 fails, the busbar 1 and the acquisition harness 2 can be disassembled by the connection terminal 3, so that the busbar 1 and the acquisition harness 2 are disconnected, avoiding short circuit of the acquisition line and affecting other cells, thus protecting other cells. At the same time, the damaged acquisition harness can be replaced and then installed on the busbar 1 by the connection terminal 3. No soldering is required, making maintenance convenient.

[0041] In some embodiments, please refer to Figure 3 and Figure 4 or Figure 8 and Figure 9 The mounting hole 10 includes a first mounting surface 104 and a second mounting surface 105 disposed opposite to each other. The first mounting surface 104 is provided with a positioning hole 101, and the second mounting surface 105 is provided with a positioning groove 102. The connecting terminal 3 includes a first connecting portion 301 and a second connecting portion 302 disposed opposite to each other. A positioning block 305 that mates with the positioning hole 101 is provided on the surface of the first connecting portion 301 facing away from the second connecting portion 302. A positioning boss 303 that mates with the positioning groove 102 is provided on the surface of the second connecting portion 302 facing away from the first connecting portion 301. In some embodiments, the positioning boss 303 is a strip-shaped protrusion extending along the width direction of the second connecting portion 302.

[0042] It is understood that the positioning hole 101 can be a through hole penetrating the first mounting surface 104 and the surface of the busbar 1. The positioning groove 102 can be a recessed structure recessed into the second mounting surface 105. In some embodiments, the positioning groove 102 is a strip-shaped groove extending along the width direction of the second mounting surface 105. The positioning block 305 can be inserted into the positioning hole 101, and the positioning boss 303 can be confined within the positioning groove 102.

[0043] In the technical solution of this application embodiment, the above-mentioned settings enable the connection terminal 3 to be installed into the mounting hole 10, and the positioning block 305 to be inserted into the positioning hole 101, with the positioning boss 303 limited within the positioning groove 102. This allows the connection terminal 3 to be stably fixed in the busbar 1 to form a stable connection, preventing the busbar 1 and connection terminal 3 from separating due to the shaking of the battery cell, thus avoiding abnormal voltage or temperature data acquisition.

[0044] In some embodiments, please refer to Figure 3 The first mounting surface 104 is provided with an inlet groove 103 near the opening of the mounting hole 10. The inlet groove 103 extends from the opening of the mounting hole 10 towards the positioning hole 101. The inlet groove 103 is connected to the positioning hole 101, and the groove width of the inlet groove 103 is consistent with the hole diameter of the positioning hole 101.

[0045] It is understandable that the guide groove 103 serves to guide the positioning block 305 to the positioning hole 101. The guide groove 103 can be a groove structure formed by recessing from the first mounting surface 104 in a direction away from the mounting hole 10.

[0046] In the technical solution of this application embodiment, since the height of the top surface of the positioning block 305 is greater than the distance between the first mounting surface 104 and the second mounting surface 105 of the mounting hole 10, in order to facilitate installation, an inlet groove 103 is provided on the first mounting surface 104. The inlet groove 103 is connected to the positioning hole 101 and the groove width of the inlet groove 103 is consistent with the hole diameter of the positioning hole 101. Therefore, during installation, the positioning block 305 of the connecting terminal 3 can be directly aligned with the inlet groove 103, and the connecting terminal 3 can be pushed to insert it into the positioning hole 101. At the same time, the positioning boss 303 is limited to the positioning groove 102.

[0047] In some embodiments, please refer to Figure 4 or Figure 9 The connecting terminal 3 also includes a middle portion 304, which is connected to one end of the first connecting portion 301 and the second connecting portion 302. The other ends of the first connecting portion 301 and the second connecting portion 302 extend freely from the middle portion 304 away from the middle portion 304 at intervals, so as to form a deformation space 307 between the first connecting portion 301 and the second connecting portion 302.

[0048] It is understood that the first connecting portion 301 can be plate-shaped or sheet-shaped, and the second connecting portion 302 can be plate-shaped or sheet-shaped. The intermediate portion 304 can be plate-shaped or sheet-shaped. The intermediate portion 304 is connected to one end of the first connecting portion 301 and the second connecting portion 302, and the other ends of the first connecting portion 301 and the second connecting portion 302 extend freely away from the intermediate portion 304 at intervals. In some embodiments, the first connecting portion 301, the intermediate portion 304, and the second connecting portion 302 form a U-shaped structure. The deformation space 307 is a deformation space that allows the first connecting portion 301 or the second connecting portion 302 to undergo elastic deformation due to pressure.

[0049] In the technical solution of this application embodiment, the above-mentioned arrangement allows the first connecting part 301 and the second connecting part 302 to be pressed together within the deformation space 307 during installation, facilitating the insertion of the connecting terminal 3 into the mounting hole 10. After insertion, the first connecting part 301 and the second connecting part 302 are released, and under their own elastic force, the first connecting part 301 and the second connecting part 302 recover their deformation and adhere to the first mounting surface 104 and the second mounting surface 105. At the same time, the positioning block 305 is inserted into the positioning hole 101, and the positioning boss 303 is limited within the positioning groove 102, thereby achieving a stable connection between the connecting terminal 3 and the mounting hole 10.

[0050] In some embodiments, please refer to Figure 4 or Figure 9A fixing member 306 is provided on the surface of the second connecting part 302 facing the first connecting part 301, and the acquisition wire harness 2 is connected to the second connecting part 302 through the fixing member 306.

[0051] It is understandable that the fastener 306 is a structural component used to fix the acquisition harness 2 to the second connection part 302.

[0052] In the technical solution of this application embodiment, through the above-mentioned arrangement, the acquisition harness 2 and the second connection part 302 are connected by the fixing member 306 so as to realize the electrical connection between the acquisition harness 2 and the connection terminal 3.

[0053] In some embodiments, please refer to Figure 4 or Figure 9 The fastener 306 includes two oppositely arranged fasteners. One end of the fastener is fixedly connected to the surface of the second connecting part 302, and the other end of the fastener is inclined upward toward the other fastener. The acquisition wire harness 2 is fixed to the second connecting part 302 by welding or snap-fitting through the fasteners.

[0054] It is understood that the fixing plate can be a structural component capable of deformation to secure the end of the acquisition harness 2. In some embodiments, the acquisition harness 2 is placed between two fixing plates, and then the fixing plates are pressed against the acquisition harness 2 with a tool to secure it firmly. In other embodiments, the fixing plates can also be connected to the acquisition harness 2 by welding.

[0055] In the technical solution of this application embodiment, the above settings are used to achieve a fixed connection between the acquisition harness 2 and the connection terminal 3.

[0056] In some embodiments, please refer to Figure 4 The positioning block 305 is cylindrical. For other embodiments, please refer to... Figure 9 The positioning block 305 is a spherical or hemispherical protrusion. The length of the positioning block 305 extending into the positioning hole 101 is less than the depth of the positioning hole 101. In some embodiments, the length of the positioning block 305 extending into the positioning hole 101 is controlled to be 1 / 10 to 4 / 5 of the depth of the positioning hole 101.

[0057] In the technical solution of this application embodiment, the above-mentioned settings facilitate the easy insertion of the positioning block 305 into the positioning hole 101, and also facilitate the easy removal of the positioning block 305 from the positioning hole 101, thus facilitating the installation and removal of the connection terminal 3 and the busbar 1.

[0058] In some embodiments, the length, width, and height of the mounting hole 10 may correspond to the length and width of the connecting terminal 3 and the height distance between the first connecting portion 301 and the second connecting portion 302. This is so that after the connecting terminal 3 is inserted into the mounting hole 10, the outer sides of the first connecting portion 301, the second connecting portion 302, and the intermediate portion 304 can fit against the hole wall of the mounting hole 10 to conduct electricity.

[0059] On the other hand, this application also provides a battery pack including the aforementioned data acquisition component. Please refer to... Figure 5 or Figure 10 The acquisition harnesses 2 of multiple acquisition components are connected to the bus harness 4. The bus harness 4 gathers the acquisition harnesses 2 of all the cells and then connects to the outside world through the connector 5.

[0060] On the other hand, this application also provides an electrical device including the aforementioned battery pack. This electrical device can be, but is not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Among them, electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc., and spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.
