[0026] like Figure 1 As shown, this application provides an integrated electrode connector, which includes an electrical connection component 100. The electrical connection component 100 includes a first connection portion 110, an adapter portion 120, and a second connection portion 130. The first connection portion 110 is used for electrical connection with the tabs in the battery module, and the second connection portion 130 is used for electrical connection with external devices. One end of the adapter portion 120 is connected to the first connection portion 110, and the other end of the adapter portion 120 is connected to the second connection portion 130. The first connection portion 110, the adapter portion 120, and the second connection portion 130 are integrally formed.
[0027] In one specific embodiment, the electrical connection component 100 is entirely made of a metal material with good conductivity. The electrical connection component 100 is the core component for realizing the entire electrode connection function. The first connection portion 110 is elongated and is used to establish an electrical connection with the tabs in the battery module. The tabs are metal conductors that lead the positive and negative electrodes out of the battery cell, and their function is to conduct the current inside the battery cell. The second connection portion 130 is rectangular and is used to directly establish an electrical connection with an external device, which can be any device that requires battery power. The adapter portion 120 is rectangular and acts as a transition and bridge. One end of the adapter portion 120 is connected to the first connection portion 110, and the end of the adapter portion 120 away from the first connection portion 110 is connected to the second connection portion 130, allowing current to be smoothly transmitted from the battery module to the external device.
[0028] In summary, the one-piece molded electrical connection component 100 significantly improves the mechanical strength of the overall structure, ensuring that the various parts of the one-piece electrode connector will not loosen during use, providing a stable and reliable electrical connection, and effectively reducing the risk of failure due to poor connection. Furthermore, due to its simple one-piece structure, installation and disassembly are more convenient, effectively shortening production and maintenance time and reducing costs.
[0029] like Figure 2 As shown, the first connecting part 110 and the adapter part 120 are located on the same plane, and the plane where the second connecting part 130 is located is perpendicular to the plane where the adapter part 120 is located.
[0030] In one specific embodiment, the first connecting part 110 and the adapter part 120 are positioned in a relatively flat relationship. This design facilitates a compact layout within the battery module, saving space. The structural design where the plane of the second connecting part 130 is perpendicular to the plane of the adapter part 120 primarily considers the connection method and spatial adaptability with external devices. In many practical applications, the interface position and orientation of external devices are fixed. This perpendicular design allows the second connecting part 130 to interface with external devices more conveniently and directly, achieving a fast and stable electrical connection.
[0031] In summary, from a space utilization perspective, the first connecting portion 110 and the adapter portion 120, which are on the same plane, can better fit the internal structure of the battery module, reduce space occupation, and improve the integration of the battery module. Meanwhile, the vertical second connecting portion 130 facilitates connection with external devices, adapting to the interface directions of different types of external devices and increasing the versatility of the connector.
[0032] like Figure 2 As shown, the first connecting part 110 is provided with a through groove 111, which passes through the first connecting part 110. The electrode tab passes through the through groove 111 and is welded and fixed to the first connecting part 110.
[0033] In one specific embodiment, the first connecting portion 110 has an elongated through groove 111 in the middle, which extends through the first connecting portion 110. After the electrode tab passes through the through groove 111, it is welded and fixed to the first connecting portion 110. The design of the through groove 111 allows the electrode tab to be accurately positioned on the first connecting portion 110, facilitating subsequent welding operations. The presence of the through groove 111 provides an accurate installation position for the electrode tab, avoiding problems such as offset or misalignment during welding, and ensuring the quality and stability of the welding.
[0034] In summary, the positioning function of the through groove 111 makes the welding between the electrode tab and the first connecting part 110 more robust and reliable, reducing problems such as poor contact caused by weak welding.
[0035] like Figure 2 and Figure 3 As shown, the integrated electrode connector also includes a cover 200, which includes a cover body 210. The shape of the cover body 210 matches the shape of the adapter 120 and the second connection 130. The cover body 210 is used to insulate the adapter 120 and the second connection 130.
[0036] In one specific embodiment, the covering 200 is entirely made of plastic material and has insulating properties. The covering 200 is used to protect and insulate the electrical connection component 100. The covering body 210 is the main component of the covering 200. The shape of the covering body 210 matches the adapter portion 120 and the second connecting portion 130, allowing the covering body 210 to tightly wrap around the adapter portion 120 and the second connecting portion 130. Furthermore, the material of the covering body 210 isolates the adapter portion 120 and the second connecting portion 130 from the outside environment, preventing current leakage and avoiding safety issues such as short circuits.
[0037] In summary, the enclosure 200 plays a crucial role in safety and protection. Firstly, the insulating enclosure prevents current leakage, avoiding short circuits and electric shocks. Secondly, the enclosure 200 protects the adapter 120 and the second connection 130 from external environmental influences, effectively protecting the electrical components and ensuring their normal operation even in harsh environments, thus improving the reliability and stability of the equipment.
[0038] like Figure 2 and Figure 3 As shown, the electrical connection component 100 also includes a plurality of fixing posts 131, which are fixedly disposed on the second connection portion 130. The covering body 210 is provided with a plurality of receiving posts 211, the fixing posts 131 and the receiving posts 211 are matched, and the fixing posts 131 are embedded in the receiving posts 211 to fix the relative positions of the electrical connection component 100 and the covering component 200.
[0039] In one specific embodiment, the fixing post 131 is a cylindrical structure vertically disposed on the second connecting part 130. Two fixing posts 131 are provided, spaced apart. The function of the fixing posts 131 is to fix the relative position of the electrical connection component 100 and the covering component 200. The receiving post 211 is a cylindrical structure on the covering body 210 that matches the fixing post 131. The receiving post 211 is hollow, and its hollow portion is a first columnar groove 216. The shape of the first columnar groove 216 matches the shape of the fixing post 131. When the fixing post 131 is embedded in the first columnar groove 216, a tight connection between the first columnar groove 216 and the covering component 200 is achieved. This design is similar to a mortise and tenon structure. Through the mutual cooperation between the two components, a stable connection is achieved, effectively preventing the covering component 200 from shifting or falling off during use, thus ensuring the effectiveness of the insulation covering.
[0040] like Figure 3 As shown, the covering body 210 includes a receiving groove 212 and several fixing plates 213. The receiving column 211 and the fixing plates 213 are both located in the receiving groove 212, and the fixing plates 213 are distributed around the receiving column 211.
[0041] In one specific embodiment, the receiving groove 212 is a rectangular groove structure on the covering body 210 for placing the receiving column 211. The receiving groove 212 provides a space for placing the receiving column 211, and the sidewall of the receiving groove 212 also enhances the overall structural stability of the covering 200. The fixing plate 213 is a rectangular plate structure disposed in the receiving groove 212, and the fixing plate 213 is evenly distributed around the receiving column 211. One side of the fixing plate 213 is connected to the receiving column 211, and the other side is connected to the sidewall of the receiving groove 212. The function of the fixing plate 213 is to strengthen the structural stability of the receiving column 211 and prevent the receiving column 211 from being damaged by external forces.
[0042] like Figure 3 As shown, the covering 200 also includes a support strip 220. The support strip 220 is provided with a fixing groove. The shape of the fixing groove matches the shape of the first connecting part 110. The edge of the first connecting part 110 is embedded in the fixing groove.
[0043] In one specific embodiment, the support strip 220 is a component of the covering 200. The support strip 220 is elongated and its length matches the length of the first connecting portion 110. The support strip 220 is fixedly connected to the covering body 210, and it serves to support and fix the first connecting portion 110. The fixing groove is a groove-shaped structure on the support strip 220 that matches the shape of the first connecting portion 110. When the edge of the first connecting portion 110 is embedded in the fixing groove, the support strip 220 can provide additional support to the first connecting portion 110, preventing it from deforming or being damaged due to stress.
[0044] like Figure 3 As shown, the first connecting part 110 has several notches 112 at its edge and several protrusions 221 in its fixing groove. The notches 112 match the protrusions 221 and the protrusions 221 are embedded in the notches 112.
[0045] In one specific embodiment, the notch 112 is a recessed portion located at the edge of the first connecting portion 110. The notch 112 is approximately rectangular, and several notches 112 are evenly spaced on the first connecting portion 110. The protrusion 221 is a raised portion in the fixing groove that matches the notch 112. Several protrusions 221 correspond one-to-one with several notches 112. When the protrusion 221 is embedded in the notch 112, it further enhances the connection stability between the first connecting portion 110 and the support strip 220. This snap-fit-like structural design makes the connection between the first connecting portion 110 and the support strip 220 tighter and less prone to separation.
[0046] In summary, the design of the notch 112 and the protrusion 221 not only enhances the connection strength between the first connecting part 110 and the support strip 220, but also improves the stability of the entire integrated electrode connector. In actual use, even under significant external force, the first connecting part 110 and the support strip 220 maintain a tight connection, avoiding various problems caused by loose connections.
[0047] like Figure 3 As shown, the receiving groove 212 includes a first sidewall 214, and a plurality of fixing holes 215 are provided on the first sidewall 214. The fixing holes 215 penetrate through the first sidewall 214, and the integrated electrode connector is fixed through the fixing holes 215.
[0048] In one specific embodiment, the first sidewall 214 of the receiving groove 212 is one side of the receiving groove 212. In this embodiment, the first sidewall 214 is provided with two fixing holes 215, which penetrate through the first sidewall 214. The function of the fixing holes 215 is to fix the integrated electrode connector to its components. Typically, bolts, screws, or other connectors can be passed through the fixing holes 215 to securely connect the electrode connector to the reinforcing beam in the battery module. This fixing method is simple and reliable, and can effectively fix the electrode connector in the required position, ensuring its normal operation.
[0049] In summary, the mounting hole 215 facilitates the installation of the integrated electrode connector. Through the mounting hole 215, the integrated electrode connector can be easily installed in various positions to adapt to different application scenarios.
[0050] like Figure 2 As shown, the fixing post 131 is hollow, and the hollow part of the fixing post 131 is the mounting hole 132. The external equipment is fixedly installed to the second connecting part 130 through the mounting hole 132.
[0051] In one specific embodiment, the fixing post 131 is hollow, and the hollow part of the fixing post 131 serves as a mounting hole 132. The mounting hole 132 is exposed, and external devices can be fixedly installed with the second connecting part 130 by means of bolts, screws, or other connectors passing through the mounting hole 132, thereby achieving an electrical connection between the external device and the second connecting part 130. This design facilitates the installation of external devices, saves space, and simplifies the structure.

In this embodiment, the specific structure of the battery module is not limited, as long as the battery module includes the integrated electrode connector.
