Description

Technical Field

[0001] This application relates to the technical field of electrical equipment, and in particular to an OT terminal and a battery. Background Technology

[0002] With the development of electrical equipment technology, an OT terminal connector technology disclosed in CN204464517U has emerged. The OT terminal is installed in the housing, and the cable is then clamped in the circular groove on the cover. The cover is then fastened to the housing. When the cover is pressed down, the cover clamps the cable on it through the slots at both ends of the guide structure and clamps it onto the OT terminal. The cutting edge of the slot pierces the cable sheath, making the cable electrically connected to the OT terminal. However, this technology neglects the monitoring and acquisition of the connector voltage, making it impossible to perform accurate voltage sampling, which is not conducive to monitoring the battery status.

[0003] However, the aforementioned OT terminals have some drawbacks:

[0004] 1. New energy batteries have strict requirements for voltage and temperature monitoring of individual battery cells. Typically, two OT terminals need to be installed on each battery cell—one for voltage acquisition and the other for temperature monitoring. This is cumbersome to install and takes up a lot of installation space.

[0005] 2. A quick connection is achieved by piercing the cable sheath. However, this design focuses on improving ease of installation but neglects high-precision sampling of voltage signals. It cannot integrate temperature monitoring functionality and still requires additional terminals and wiring harnesses, making it difficult to meet the system monitoring needs of new energy batteries.

[0006] This utility model was developed to address the common problems in the field, such as dual-terminal solutions occupying a large amount of installation space, dense and untidy battery wiring, increased installation complexity due to the use of multiple terminals and cables, susceptibility to external interference, and inaccurate monitoring data. Utility Model Content

[0007] Therefore, it is necessary to provide an OT terminal and battery to address the problems of dual-terminal solutions occupying a large amount of installation space, dense and messy battery wiring, increased installation complexity due to the use of multiple terminals and cables, susceptibility to external interference, and inaccurate monitoring data.

[0008] In a first aspect, this application provides an OT terminal, which adopts the following technical solution:

[0009] An OT terminal, comprising:

[0010] The collection section has through holes for connecting parts to pass through;

[0011] The wiring section has a cavity, which is nested on the outer periphery of the end of the acquisition section away from the through hole. The cavity contains and integrates a voltage acquisition line and two temperature acquisition lines. The voltage acquisition line is located inside the cavity and connected to the acquisition section.

[0012] A temperature sensor is built into the cavity and electrically connected to the two temperature acquisition lines.

[0013] In one embodiment, the temperature contact surface of the temperature sensor is in contact with the end face of the acquisition unit body.

[0014] In one embodiment, the main body of the collecting unit is a circular conductive sheet.

[0015] In one embodiment, a covering layer is provided outside the wiring cavity.

[0016] In one embodiment, the voltage acquisition line and the two temperature acquisition lines disposed in the cavity extend along one end face away from the acquisition part.

[0017] Secondly, this utility model provides a battery, the battery comprising: a housing and a battery cell, a busbar bracket and a busbar disposed in the housing, the busbar being placed on the busbar bracket and electrically connected to the battery cell, wherein the OT terminal is detachably connected to the busbar.

[0018] In one embodiment, the busbar bracket is provided with a wiring section for placing the voltage acquisition line and the two temperature acquisition lines.

[0019] In one embodiment, the housing includes end plates, side plates, and cover plates, with two oppositely arranged end plates, two oppositely arranged side plates, and two oppositely arranged cover plates joined together to form the housing.

[0020] In one embodiment, an insulating baffle is also provided between the end plate and the busbar support.

[0021] In one embodiment, the busbar bracket and the side plate are detachably connected.

[0022] This application has at least the following beneficial effects:

[0023] The aforementioned OT terminals, through the cooperation of the acquisition section and the wiring section, enable the voltage acquisition line to be reliably connected to the acquisition section. At the same time, the wiring section's covering layer isolates external interference, ensuring the high efficiency of voltage acquisition and the stability of the signal.

[0024] The aforementioned OT terminal, through the cooperation between the acquisition unit and the cavity, allows the acquisition unit to be firmly wedged into the cavity body. At the same time, the acquisition unit is directly connected to the voltage acquisition line, realizing efficient current conduction and signal acquisition functions, ensuring the excellent conductivity and accurate signal transmission of the entire OT terminal.

[0025] The aforementioned OT terminal, through the interaction between the wiring section and the cavity, enables the cavity to provide space for placing voltage acquisition lines, temperature acquisition lines, and temperature sensors. The wiring section's covering layer enhances safety, ensuring that the entire OT terminal has good protection and reliability in complex working environments. Attached Figure Description

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and 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, and therefore should not be construed as a limitation of this application.

[0036] Furthermore, where the terms "first" and "second" appear, these terms are 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 with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] like Figure 1 As shown, this utility model provides an OT terminal, including a data acquisition unit 1, a wiring unit, and a temperature sensor 4. The data acquisition unit 1 has a through hole 2 for a connector to pass through. The wiring unit has a cavity 3, which is nested on the outer periphery of the end of the data acquisition unit 1 away from the through hole 2. The cavity 3 houses and integrates a voltage acquisition line 6 and two temperature acquisition lines 5. The voltage acquisition line 6 is located inside the cavity 3 and connected to the main body of the data acquisition unit 1. The temperature sensor 4 is built into the cavity 3 and electrically connected to the two temperature acquisition lines 5. Through the cooperation of the data acquisition unit 1 and the wiring unit, the voltage acquisition line 6 can be reliably connected to the data acquisition unit 1. At the same time, the wiring unit isolates external interference, ensuring high efficiency of voltage acquisition and signal stability.

[0041] In this embodiment, the OT terminal for voltage acquisition and the OT terminal for temperature acquisition are integrated into a single OT terminal. This optimized design achieves structural and functional integration, significantly saving internal battery space and improving operational convenience and OT terminal reliability. The integrated OT terminal design involves soldering the voltage acquisition line 6 to the OT terminal body and tightly fixing the temperature sensor 4 to the OT terminal. Simultaneously, the temperature acquisition line 5 is connected to the temperature sensor 4, forming an integrated, modular, and highly efficient monitoring and connection solution.

[0042] Integrating a single OT terminal effectively saves space. Compared to traditional dual-terminal designs that require more installation space and wiring, integrated terminals reduce the number of wires within the module by combining voltage acquisition and temperature monitoring functions, resulting in cleaner and neater wiring. This facilitates optimized module layout and is particularly suitable for applications with strict space requirements, such as electric vehicle batteries, energy storage devices, and industrial batteries.

[0043] By reducing space occupation, the heat dissipation performance of OT terminals is further improved, the wiring complexity is reduced, and subsequent maintenance and operation are made more convenient.

[0044] In this embodiment, the integrated design significantly improves assembly efficiency. Traditional methods require separate soldering, fixing, and cable connection of two OT terminals; now, all connection tasks can be completed by installing only one terminal at a time, reducing assembly steps by half. For the production line, the reduced steps not only shorten production time but also significantly reduce manpower requirements and improve production line efficiency.

[0045] The design, integrating components onto a single OT terminal, effectively reduces manufacturing costs. By consolidating the functions of two terminals into a single unit, material usage and processing complexity are reduced, lowering production overhead. Using one less terminal means less consumption of metal raw materials, while also reducing mold development and process costs. Furthermore, the integrated design also reduces logistics and storage costs, as the reduction in the types and number of parts simplifies supply chain management.

[0046] The integrated design also improves the reliability and monitoring accuracy of the OT terminal. Through integrated design, the signal paths for voltage acquisition and temperature monitoring are shorter, reducing external environmental interference and ensuring signal stability. At the same time, the integrated terminal reduces the number of connection points, fundamentally reducing the risk of poor contact caused by vibration, loosening, and other factors, making the OT terminal safer and more reliable.

[0047] In summary, the OT terminal design, which integrates voltage and temperature acquisition functions, provides an efficient and economical solution for new energy batteries by saving space, improving assembly efficiency, reducing costs, and enhancing OT terminal reliability. It has broad market application prospects and technological promotion value.

[0048] In this embodiment, the temperature contact surface of the temperature sensor 4 is in contact with the end face of the acquisition unit body, thereby improving the reliability of temperature signal transmission.

[0049] Voltage acquisition line 6 and temperature acquisition line 5 are built into and integrated in cavity 3, and stable transmission of voltage and temperature signals is achieved through precise internal wiring.

[0050] The internal structure of cavity 3 has been optimized to not only accommodate voltage acquisition line 6 and temperature acquisition line 5, but also to protect temperature sensor 4, enabling it to work stably in harsh environments.

[0051] In addition, the temperature sensor 4 is built into the cavity 3 and is connected to external devices via two temperature acquisition lines 5. This temperature sensor 4, through close contact with the acquisition unit 1 using thermally conductive material, can quickly respond to temperature changes in the device under test, thereby achieving accurate monitoring.

[0052] The electrical connection of temperature sensor 4 uses high-reliability terminals, and the temperature signal is transmitted to the battery management system (BMS) through an independent signal processing channel to ensure the accuracy and stability of data transmission.

[0053] In this embodiment, the battery management system (BMS) is a device and instrument well known to those skilled in the art, as well as a technical means well known to those skilled in the art. Those skilled in the art can consult relevant technical manuals to learn about this technology, so it will not be described in detail in this embodiment.

[0054] Traditional OT terminal blocks require separate fixing and cable routing for voltage and temperature acquisition OT terminals during installation, which is cumbersome and prone to errors. By integrating voltage and temperature acquisition onto a single OT terminal, users can quickly complete all assembly work on a single terminal.

[0055] On one hand, the voltage acquisition line 6 is connected to the acquisition unit 1 by welding, and the connection part stabilizes the terminal position to ensure welding accuracy. On the other hand, the temperature sensor 4 is installed inside the cavity 3 and directly connected to the temperature acquisition line 5, avoiding problems such as loose or messy cable arrangement. The optimized design of the OT terminal integrates multiple independent operations into one-time completion, significantly improving assembly efficiency and saving production line time and labor costs.

[0056] In terms of operational safety, the wiring section further enhances the overall performance of the terminals. During installation and assembly, operators can use the wiring section to securely position the terminals, avoiding the risk of poor contact or short circuits caused by slippage. Furthermore, the cavity effectively isolates internal components from external dust and moisture, further improving the long-term stability and reliability of the terminals. For high-frequency maintenance scenarios, the wiring section also provides additional convenience for disassembly and replacement, allowing operators to quickly remove terminals without the need for additional tools.

[0057] like Figure 2 and Figure 3 As shown, the main body of the collecting part 1 is a flat circular conductive sheet with two parallel end faces. A through hole 2 is provided on the end face of the main body of the collecting part 1, and the through hole 2 penetrates the main body of the collecting part 1. In this embodiment, the opening direction of the through hole 2 is perpendicular to the end face of the main body of the collecting part 1.

[0058] Optionally, a covering layer is provided outside the wiring cavity. The covering layer is made of insulating material. Both the cavity 3 and the covering layer 14 can be made of epoxy resin and a hardener, integrally molding the temperature sensor 4 onto the acquisition unit 1. Alternatively, the cavity 3 can be installed at the acquisition unit 1, and then the covering layer is formed outside the cavity 3 using insulating material. The covering layer is made of insulating material, and its insulating properties can effectively isolate the voltage acquisition line 6 from electrical interference from the external environment, thereby improving the safety of the entire OT terminal.

[0059] Optionally, the acquisition unit 1 uses a conductive metallic material. The acquisition unit 1 uses a highly conductive metallic material, such as silver, copper, or nickel-plated copper. Its superior conductivity ensures efficient voltage signal transmission and significantly reduces contact resistance. Nickel plating not only enhances corrosion resistance but also improves the wear resistance of the metal surface, making it suitable for complex industrial environments or outdoor applications.

[0060] Meanwhile, the high strength of the metal material ensures that the collecting unit 1 can maintain stable mechanical properties during long-term use, avoiding deformation caused by vibration or external force.

[0061] Furthermore, the direct welding of the conductive metal material of the acquisition unit 1 to the voltage acquisition line 6 further optimizes the electrical connection performance. At the same time, it reduces the use of intermediate interfaces, lowers resistance and interference in the signal path, and makes voltage signal acquisition more accurate and stable, making it particularly suitable for battery applications requiring high monitoring accuracy.

[0062] Optionally, the voltage acquisition line 6 and two temperature acquisition lines 5, located in the cavity 3, extend along the side facing away from the acquisition unit 1, with the two temperature acquisition lines 5 symmetrically arranged on both sides of the voltage acquisition line 6. To achieve a compact structure and stable signal transmission, the arrangement of the voltage acquisition line 6 and the two temperature acquisition lines 5 has been carefully designed. In the cavity 3, the voltage acquisition line 6 is located in the middle, and the two temperature acquisition lines 5 are symmetrically arranged on both sides of the voltage acquisition line 6. This symmetrical arrangement not only improves the neatness of the cable arrangement but also gives the temperature signal acquisition a higher anti-interference capability.

[0063] Voltage acquisition line 6 and temperature acquisition line 5 extend from the side of cavity 3 away from acquisition unit 1, ensuring a uniform cable exit direction for easy subsequent connection and fixation. The parallel arrangement of voltage acquisition line 6 and temperature acquisition line 5 allows users to easily identify and separate cables with different functions during installation, avoiding incorrect connections or short circuits caused by messy cable arrangement. This design is particularly suitable for scenarios with multiple cable connections, such as monitoring large energy storage battery packs (up to 9) or electric vehicle batteries.

[0064] A well-designed cable layout significantly improves terminal assembly efficiency. In practical use, users do not need to painstakingly distinguish cable functions and can quickly complete connections through the symmetrical design. Furthermore, the uniformity of cable exit directions makes wiring more intuitive, especially in confined spaces or high-density modules, facilitating installation and debugging.

[0065] During maintenance, the symmetrical cable arrangement and consistent cable extension direction allow operators to quickly identify and disconnect relevant cables without requiring additional adjustments or disassembly of other components. For equipment requiring periodic replacement or testing, the symmetrical cable arrangement and consistent cable extension direction significantly shorten maintenance time and reduce labor intensity.

[0066] By using a metallic conductive material in the acquisition unit 1 and optimizing the arrangement of the voltage acquisition line 6 and the temperature acquisition line 5, this OT terminal has significant advantages in the following aspects:

[0067] 1) Conductivity: The metal material of the acquisition unit 1 improves the transmission efficiency of voltage signals and reduces power loss.

[0068] 2) Signal stability: The symmetrically arranged temperature acquisition lines 5 reduce the risk of interference in signal acquisition and ensure the accuracy of temperature monitoring.

[0069] 3) Assembly efficiency: The cables exit in the same direction, which facilitates quick installation and is especially suitable for mass production and large-scale equipment assembly.

[0070] 4) Ease of maintenance: The optimized cabling design allows users to quickly troubleshoot or replace components, reducing maintenance time and costs.

[0071] In this embodiment, the optimization of the material of the acquisition unit 1 and the fine adjustment of the cable arrangement not only significantly improve the performance and ease of operation of the terminals, but also meet the urgent needs of modern new energy equipment for efficient, accurate and reliable connection solutions.

[0072] In addition, this utility model provides a battery, such as Figure 4 , Figure 6 and Figure 7 As shown, the battery includes a housing and a battery cell 11, a busbar bracket 10, and a busbar 8 disposed in the housing. The busbar 8 is placed on the busbar bracket 10 and electrically connected to the battery cell 11. The OT terminal is detachably connected to the busbar 8.

[0073] In this invention, the OT terminal is fixed to the busbar 8 by bolts 7, and the busbar 8 is further placed on the busbar bracket 10. The bolts 7 are adapted to the through holes 2 provided on the OT terminal. The detachable design brings significant convenience to installation and maintenance. During assembly, by directly installing the OT terminal onto the busbar 8, the user can quickly complete the terminal fixing without using complex tools or special processes. Quickly fixing the terminal makes the assembly process more efficient, especially in scenarios requiring mass production or rapid repair, saving a significant amount of time. At the same time, the bolt 7 connection method provides reliable mechanical stability, ensuring a firm connection between the terminal and the busbar even in high vibration or high impact environments, avoiding loosening or poor contact.

[0074] In this invention, the main body of the busbar 8 is made of a conductive metal material. The busbar 8 is made of a highly conductive metal material (such as copper or nickel-plated copper). Highly conductive metal materials have extremely low resistance and excellent conductivity, enabling efficient power transmission under high current conditions. The metal busbar not only reduces power loss but also has good heat dissipation performance, quickly conducting away heat generated during operation and preventing performance degradation or safety hazards at the OT terminals due to overheating. Furthermore, after undergoing anti-corrosion treatment such as nickel plating, the metal busbar can withstand environments with high humidity or strong chemical corrosion, significantly improving its durability.

[0075] Optionally, the busbar bracket is provided with a wiring section for placing the voltage acquisition line 6 and two temperature acquisition lines 5.

[0076] To further optimize the wiring of voltage acquisition line 6 and temperature acquisition line 5, a dedicated wiring section was designed at the busbar bracket. This section provides a fixed path for the cables. Voltage acquisition line 6 and the two temperature acquisition lines 5 extend from the side of cavity 3 away from acquisition section 1, with the two temperature acquisition lines 5 symmetrically arranged on both sides of voltage acquisition line 6. This symmetrical arrangement of the two temperature acquisition lines 5 ensures neat cable arrangement, avoiding interference caused by messy or crossed cables. This not only improves signal acquisition accuracy but also facilitates subsequent maintenance and management. The centralized cable arrangement combined with the fixing function of the wiring section makes battery 9 more stable during operation, reducing the risk of failure due to loose or worn cables.

[0077] like Figure 5 As shown, the box body includes end plates 12, side plates 9 and cover plates. The two oppositely arranged end plates 12, the two oppositely arranged side plates 9 and the two oppositely arranged cover plates are assembled to form the box body.

[0078] Optionally, an insulating baffle 13 is also provided between the end plate 12 and the busbar bracket 10.

[0079] Optionally, the busbar bracket 10 and the side plate 9 are detachably connected.

[0080] The installation of the insulating baffle 13 improves the overall safety of the battery, while the detachable connection between the busbar bracket 10 and the side plate 9 brings many benefits to the overall performance. The modular design of the busbar bracket 10 makes the assembly of the entire battery more efficient, and users can choose different specifications of busbar bracket 10 and busbar 8 combinations according to specific needs, thus adapting to various battery application scenarios. Furthermore, the fixing method of the busbar bracket 10 and the side plate 9 improves maintenance convenience.

[0081] This application optimizes the connection between the voltage acquisition OT terminal and the temperature monitoring OT terminal and the busbar 8 and busbar bracket 10 by integrating the voltage acquisition OT terminal and the temperature monitoring OT terminal into a single OT terminal. This improves assembly efficiency and maintenance convenience. By optimizing the cable wiring design, it significantly improves the space utilization and overall efficiency of the battery, providing a safe, reliable and efficient connection solution for electric vehicles, energy storage equipment and other fields.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
