[0025] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, clearly and comprehensively demonstrating the technical solution. It should be noted that the listed embodiments are only a part of this utility model, and not all possible implementations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of the power connector 00 and the battery together according to an embodiment of the present invention. Figure 2 This is a cross-sectional schematic diagram of the power connector 00 provided in this embodiment of the utility model.

[0027] This utility model relates to a power system comprising: a first electrical appliance, a second electrical appliance, and a power connector 00. The first electrical appliance is connected to the power connector 00, and the second electrical appliance is connected to another power connector 00. The two power connectors 00 are elastically connected to each other, thereby electrically connecting the first and second electrical appliances. This technical solution, by respectively setting power connectors 00 on the first and second electrical appliances and making the two power connectors 00 elastically connected to each other, provides an effective solution to the technical problems of poor connection reliability, complex assembly, and poor contact in existing power systems. The first electrical appliance can be an electrical component such as a cable, a liquid chiller, or a water pump; the second electrical appliance can also be an electrical component such as a cable, a liquid chiller, or a water pump.

[0028] Specifically, the two electrical connectors (00) are electrically connected via a flexible abutment mechanism. This structural design automatically compensates for changes in connection gaps caused by assembly tolerances, mechanical vibration, thermal expansion and contraction, maintaining consistent contact pressure and significantly improving the stability and reliability of the electrical connection. Even during long-term operation or in harsh environments, it effectively prevents poor contact caused by loosening or oxidation, enhancing system safety and lifespan.

[0029] Furthermore, this technical solution simplifies the assembly process of the power system. The two electrical connectors (00) only need to be simply aligned and elastically abutted to complete the connection, avoiding the cumbersome screwing or welding processes of traditional connection methods. This improves assembly efficiency and facilitates later maintenance and replacement. In summary, this technical solution, by optimizing the power connection method, achieves high reliability, high stability, and convenient assembly of electrical connections, effectively solving related technical problems in existing technologies.

[0030] Please see Figures 1 to 3 As shown, Figure 3 This is an exploded view of the power connector 00 and the battery provided in this embodiment of the utility model.

[0031] In the construction of the power connector 00, in addition to the basic housing assembly 10, conductor 20, and elastic element 30, several other important structural elements are included. The housing assembly 10 is meticulously designed with three main parts: a first opening 101, a mounting cavity 102, and a second opening 103, which are connected sequentially. These three parts are arranged in an orderly manner, with the first opening 101 and the second opening 103 located at opposite ends of the housing assembly 10, ensuring smooth operation of the power connector 00. The conductor 20 is precisely placed within the mounting cavity 102, allowing for smooth sliding contact with the housing assembly 10 along the axial direction of the first opening 101. This design allows one end of the conductor 20 to freely extend beyond the first opening 101, facilitating precise docking with conductors 20 of other power connectors 00 and ensuring efficient power transmission. Simultaneously, the other end of the conductor 20 can also extend beyond the second opening 103, facilitating connection with various electrical devices and ensuring a stable power supply. In addition, the position of the elastic element 30 in the assembly cavity 102 is also carefully designed. It is in a compressed state. This design not only ensures the durability of its elasticity, but also ensures that the elastic element 30 can be firmly connected to one end of the housing assembly 10 and the conductor 20 respectively, thereby providing the necessary elastic support during the operation of the power connector 00 and ensuring the stability and reliability of the connection.

[0032] This technical solution, through innovative design of the housing assembly 10, conductor 20, and elastic element 30, effectively improves the inherent reliability of the power connector, including the stability of contact resistance, high standards of insulation resistance, and specifications for insertion and extraction forces in terms of mechanical performance. Furthermore, the solution considers the vibration and shock resistance of the electrical connector during transportation and use, ensuring the stability and reliability of the connection and meeting the stringent requirements of military electrical connectors. Specifically, in this technical solution, the conductor 20 can slide along the first opening 101 within the assembly cavity 102 of the housing assembly 10, with one end extending out of the first opening 101 of the housing assembly 10 to reliably dock with the conductor 20 of the external power connector 00, and the other end extending out of the second opening 103 for electrical connection. The elastic element 30 is in a compressed state, connected to one end of both the housing assembly 10 and the conductor 20, thereby automatically compensating for gap changes caused by tolerances, vibration, or thermal expansion during docking and continuously providing stable contact pressure. This design effectively prevents electrical performance degradation and safety hazards caused by poor contact, thereby enhancing the stability and durability of the connection.

[0033] Meanwhile, the structural design of the housing assembly 10 simplifies the assembly and disassembly of the conductor 20, facilitating later maintenance and replacement, and improving the ease of product maintenance. Furthermore, the sequentially connected layout of the first port 101, assembly cavity 102, and second port 103 optimizes the overall structure of the power connector 00, reduces its size, and facilitates miniaturization. In summary, this technical solution not only improves the electrical performance and mechanical reliability of the power connector 00 but also contributes to efficient production and maintenance, thereby achieving a safe, stable, and long-life power connection.

[0034] Please see Figures 1 to 4 As shown, Figure 4 This is a schematic diagram of the structure of the conductor 20 provided in this embodiment of the utility model.

[0035] The conductor 20 is designed with three main parts, which are integrally formed and have different functions and positions. First, the first part 21, conductor 20, extends out and is located at the first opening 101. Its main function is to contact and abut with the conductor 20 of another electrical connector 00, ensuring that current can be smoothly transferred from one connector to another. Second, the second part 22, conductor 20, extends out and is located at the second opening 103. Its purpose is to connect with electrical equipment, allowing current to flow from conductor 20 to the appliance, thereby providing the appliance with the required power. Finally, the third part 23, conductor 20, is designed to slide with the housing assembly 10. This design ensures both the flexibility of the connection and a tight fit between conductor 20 and housing assembly 10, maintaining the stability and safety of the overall structure.

[0036] This technical solution addresses the technical problems of existing power connectors 00, such as complex structure, difficult assembly, and unstable electrical connection. It proposes an innovative design where the conductor 20 is a single-piece structure comprising a first part 21, a second part 22, and a third part 23. The implementation of this solution significantly enhances the structural stability and electrical efficiency of the power connector 00.

[0037] Specifically, the one-piece molding design of the conductor 20 ensures electrical continuity between various parts, avoiding problems such as increased contact resistance and overheating that may result from multi-segment splicing, thus solving the technical problem of unstable electrical connection from the source. The first part 21 extends directly from the first opening 101 for reliable docking with the conductor 20 of another electrical connector 00, effectively ensuring the electrical performance and mechanical strength of the connection interface. The second part 22 extends from the second opening 103 for connection with electrical appliances, simplifying the assembly process and improving connection efficiency and reliability. The third part 23 is slidably connected to the housing assembly 10, and in conjunction with the elastic element 30, allows the conductor 20 to move flexibly within the assembly cavity 102, effectively compensating for displacement caused by external mechanical tolerances or thermal deformation, ensuring continuous and stable contact pressure and electrical performance.

[0038] Therefore, this technical solution simplifies the number of components and assembly process by setting the conductor 20 as an integrally formed structure, reduces production and maintenance costs, improves the overall electrical performance and mechanical reliability, and achieves efficient, stable and long-life power connection, effectively solving the relevant technical problems in the prior art.

[0039] The elastic element 30 is fitted onto the outer peripheral surface of the first part 21. The first part 21 limits the elastic element 30, preventing it from deforming along its axial direction perpendicular to the first part, thus ensuring that the elastic element 30 always generates elastic force in its axial direction. This design ensures that the elastic element 30 maintains its original elastic characteristics during use, avoiding unnecessary deformation caused by external forces, thereby maintaining its performance and extending its service life. At the same time, this limiting mechanism also ensures that the elastic element 30 can evenly distribute force when subjected to pressure or tension, avoiding local stress concentration, further improving the stability and reliability of the elastic element 30.

[0040] This technical solution addresses the problems in the prior art where the elastic element 30 is prone to non-axial deformation due to uneven force or external force during application, leading to decreased elastic properties, unstable performance, and shortened lifespan. It proposes a structural design in which the elastic element 30 is sleeved on the outer peripheral surface of the first part 21, and the first part 21 limits the elastic element 30.

[0041] Specifically, the elastic element 30 is fitted onto the outer peripheral surface of the first part 21, ensuring an effective elastic fit between the elastic element 30 and related components, thereby providing continuous elastic support for the device. Furthermore, the first part 21 acts as a limiter for the elastic element 30, effectively preventing unnecessary deformation of the elastic element 30 in a direction perpendicular to its axial direction. Utilizing this specific limiting structure, when the elastic element 30 is subjected to pressure or tension, its elastic deformation is restricted to the axial direction, thus ensuring the stability of its elastic properties and preventing fatigue damage.

[0042] The aforementioned structural design not only maintains the original elastic characteristics of the elastic element 30 during use, preventing performance degradation due to external disturbances, but also, through a limiting mechanism, ensures that the elastic element 30 can evenly distribute pressure or tension when subjected to external forces, avoiding localized stress concentration and effectively improving the overall stability and reliability of the elastic element 30. Simultaneously, through optimized design and material selection, the elastic element 30 achieves precise control of its stress state, reducing the risk of failure due to excessive deformation. Furthermore, through regular maintenance and proper installation precision, the service life of the elastic element 30 is significantly extended.

[0043] Through a carefully designed limiting structure, this technical solution effectively solves the problems of non-axial deformation and local stress concentration encountered by the elastic element 30 in practical applications. This improvement significantly enhances the performance stability of the elastic element 30 and ensures the high reliability of the device.

[0044] In the design, mounting grooves 24 are specifically designed between the first part 21 and the third part 23, into which some of the elastic elements 30 are precisely assembled. This design ensures that the mounting grooves 24 can effectively curb the non-axial deformation of the elastic elements 30, thereby ensuring that the elastic elements 30 always release elastic force stably along their axial direction. In addition, the presence of the mounting grooves 24 also prevents unnecessary displacement of the elastic elements 30, further enhancing the stability and reliability of the entire structure.

[0045] This technical solution addresses the problems in the prior art where the elastic element 30 is prone to non-axial deformation or displacement during use, resulting in insufficient elasticity, unstable performance, and shortened lifespan. It proposes a structural design that forms an installation groove 24 between the first part 21 and the third part 23, and assembles part of the elastic element 30 into the installation groove 24.

[0046] By forming a mounting groove 24 between the first part 21 and the third part 23, and embedding the elastic element 30 partially into the mounting groove 24, the elastic element 30 can be effectively limited, preventing it from deforming in a direction perpendicular to its axial direction when subjected to force. This design ensures that the elastic element 30 only undergoes elastic deformation in the axial direction, thereby continuously providing stable axial elastic force and avoiding a decrease in elastic performance due to lateral deformation. In addition, the containment and constraint of the mounting groove 24 on the elastic element 30 can also prevent unnecessary displacement of the elastic element 30 during use, further ensuring the stability of the working position and function of the elastic element 30.

[0047] Therefore, by setting the mounting groove 24, this technical solution effectively solves the technical problems such as the performance degradation of the elastic element 30 caused by non-axial deformation and displacement, realizes the stability and reliability of the elastic force output of the elastic element 30, extends the service life of the elastic element 30, and improves the safety and durability of the overall device.

[0048] In the axial direction perpendicular to the first opening 101, the cross-sectional area of ​​the first part 21 is S1, and the cross-sectional area of ​​the second part 22 is S2, where 1.5 ≤ S1 / S2 ≤ 4, and can be 1.5, 1.8, 2.0, 2.5, 3.0, 3.2, 3.5, 3.6, 4.0, etc. Within this range, the current carrying efficiency of the first part 21 is effectively improved, reducing the heat generated by the contact between the first parts 21. By limiting the cross-sectional area ratio, the technical problems of low current carrying efficiency of the first part 21, easy heating of the contact parts, and impact on conductivity and service life of existing power connectors 00 are effectively solved.

[0049] Specifically, by appropriately increasing the cross-sectional area of ​​the first part 21, keeping its ratio to the cross-sectional area of ​​the second part 22 within the range of 1.5 to 4, the current-carrying capacity of the first part 21 can be significantly improved. When current passes through the first part 21, the larger cross-sectional area reduces the current density per unit area, reducing resistance loss and thus effectively improving current-carrying efficiency. Simultaneously, since resistive heating is proportional to current density, increasing the cross-sectional area can also significantly reduce heat generation at the contact point between the first part 21 and the first part 22, reducing energy loss and temperature rise caused by heating, and avoiding problems such as material aging and performance degradation caused by excessive temperature rise.

[0050] Therefore, by reasonably limiting the cross-sectional area ratio of the first part 21 and the second part 22, this technical solution effectively improves current carrying efficiency, reduces contact heating, enhances the safety and reliability of power connectors, and extends their service life while ensuring the stability of electrical connections.

[0051] The housing assembly 10 mainly consists of two parts: the outer shell 11 and the cover plate 13. The outer shell 11 has three sequentially arranged and interconnected openings: a first opening 101, an assembly cavity 102, and a second opening 103. These openings facilitate the assembly of the housing assembly 10 and the installation of internal components. During assembly, the cover plate 13 is fitted into the second opening 103 to close one end of the outer shell 11. Furthermore, the other end of the conductor needs to pass through the cover plate 13 to enable the housing assembly 10 to conduct electricity. To ensure the stability of the cover plate 13 and the overall performance of the housing assembly 10, an elastic element 30 is cleverly connected to the cover plate 13 to provide the necessary elasticity, ensuring tight contact and a sealing effect between the conductor and the outer shell 11.

[0052] In this embodiment, the above-described structural design effectively solves the problems of poor sealing of the housing assembly 10, unstable assembly of the conductor, and easy detachment of the elastic element 30 in the prior art. First, by sequentially providing a first opening 101, an assembly cavity 102, and a second opening 103 on the outer shell 11, and assembling the cover plate 13 into the second opening 103, the assembly and positioning of each component is facilitated, improving the overall structural strength and sealing performance of the housing assembly 10, preventing external dust and moisture from entering the assembly cavity 102, and enhancing the reliability and service life of the product. Second, the cover plate 13 passes through the other end of the conductor, allowing the conductor to be stably positioned within the housing assembly 10, preventing loosening or detachment of the conductor during long-term use, and ensuring the durability and safety of the electrical connection. Third, the design of the elastic element 30 connected to the cover plate 13 ensures the stable fixation of the elastic element 30 inside the housing assembly 10, thereby providing continuous elastic pressure to the conductor, improving the reliability of electrical contact, and preventing poor contact caused by displacement of the elastic element 30.

[0053] In summary, this embodiment, with its ingenious structural design, not only improves the ease of assembly and sealing performance of the housing assembly 10, but also ensures the stable installation of the internal conductors and elastic elements 30, successfully overcoming related technical challenges and achieving a significant improvement in the structural reliability and electrical connection stability of the housing assembly 10.

[0054] The electrical connector 00 includes a waterproof ring 40 with a first groove 41. A limiting arm 15 protrudes from one end of the outer casing 11 at the first opening 101 and is inserted into the first groove 41. In use, the waterproof ring 40, by abutting against the outer casing 11 and being under appropriate compression, effectively seals the contact surfaces between adjacent conductors 20 according to the compression standard of the sealing ring.

[0055] In this embodiment, the electrical connector 00 includes a waterproof ring 40 with a first groove 41. A limiting arm 15 protrudes from one end of the outer casing 11 at the first opening 101 and is inserted into the first groove 41. During use, the waterproof ring 40 can abut against the outer casing 11 of another electrical connector 00 and be in a compressed state, thereby sealing the contact surface between adjacent conductors 20.

[0056] Through the above structural design, this technical solution effectively solves the technical problems of poor waterproof sealing effect of existing power connectors 00 and easy misalignment or detachment of waterproof rings 40.

[0057] Specifically, one end of the outer casing 11 is designed with a protruding limiting arm 15, which is inserted into the first groove 41 of the waterproof ring 40 to ensure that the waterproof ring 40 can be stably positioned in the predetermined position, effectively avoiding the problem of displacement or falling off of the waterproof ring 40 due to external force during assembly or use, thereby enhancing the assembly stability and reliability of the waterproof ring 40.

[0058] Furthermore, when electrical connector 00 is connected to another electrical connector 00, a precisely designed waterproof ring 40 abuts against the other's housing 11 and is in a compressed state, ensuring that the waterproof ring 40 can fully fill the gap between the two housings 11, forming an effective sealing structure. These measures effectively prevent external impurities such as moisture and dust from penetrating into the contact surface between the conductors 20, thereby significantly improving the waterproof performance and service life of the connectors and ensuring the safety and stability of the electrical connection.

[0059] In summary, this embodiment employs a cleverly combined structure of the limiting arm 15 and the first groove 41 of the waterproof ring 40, achieving stable fixation of the waterproof ring 40 and tight sealing of the contact surface. This successfully solves the technical problems of easy displacement of the waterproof ring 40 and poor waterproofing effect, significantly improving the sealing performance and reliability of the power connector 00.

[0060] Furthermore, it also includes a first sealing ring 50, and a second groove 43 is formed on the side of the waterproof ring 40 away from the first groove 41, and the first sealing ring 50 is fitted into the second groove 43. In use, the first sealing ring 50 abuts against the housing 11 of another electrical connector 00 and is in a compressed state, thereby sealing the contact surface between adjacent conductors 20.

[0061] This technical solution, through the above structural design, effectively solves the technical problems of limited waterproof sealing effect of existing power connectors, easy misalignment or detachment of waterproof rings 40 and sealing rings, and insufficient sealing reliability.

[0062] Specifically, a limiting arm 15 at one end of the outer casing 11 is inserted into the first groove 41 of the waterproof ring 40, allowing the waterproof ring 40 to be accurately and firmly positioned at the end of the outer casing 11. This prevents the waterproof ring 40 from shifting or falling off during assembly and use, thus improving the installation reliability of the waterproof ring 40. Simultaneously, a second groove 43 is provided on the side of the waterproof ring 40 away from the first groove 41, and the first sealing ring 50 is assembled into the second groove 43. This allows the first sealing ring 50 to be positioned together with the waterproof ring 40, further enhancing the overall stability of the sealing structure.

[0063] When the connectors are used together, the first sealing ring 50 abuts against the surface of the outer shell 11 of the other electrical connector 00 and is in a compressed state, so that the sealing ring can fully fill the gap between the connectors, effectively sealing the contact surface of the adjacent conductors 20, preventing moisture, dust and other external impurities from seeping in, improving the protection level and service life of the entire electrical connector 00, and ensuring the safety and reliability of the electrical connection.

[0064] In summary, this embodiment achieves precise fixation of the waterproof ring 40 by cooperating with the limiting arm 15 and the first groove 41 of the waterproof ring 40. By setting the second groove 43 on the waterproof ring 40 and assembling the first sealing ring 50, a multi-seal structure is achieved, thereby effectively solving problems such as seal displacement and incomplete sealing, and achieving the technical effect of improving the protection performance and reliability of the power connector 00.

[0065] In this embodiment, the power connector 00 further includes a second sealing ring 60. A limiting groove 17 is formed at one end of the outer casing 11 located at the second opening 103, and the second sealing ring 60 is fitted into the limiting groove 17. During use, the second sealing ring 60 can come into contact with the surfaces of other parts, thereby achieving an effective seal on the second opening 103.

[0066] Through the above structural design, this technical solution effectively solves the technical problems of poor sealing effect, easy detachment or misalignment of sealing ring in the second port 103 of the existing power connector 00.

[0067] Specifically, the outer casing 11 is provided with a limiting groove 17 at one end of the second opening 103, and the second sealing ring 60 is assembled in the limiting groove 17, so that the second sealing ring 60 can be reliably positioned in the designated position of the outer casing 11, avoiding the problem of displacement or falling off of the sealing ring due to external force or vibration during assembly or use, and improving the installation reliability and positional stability of the sealing ring.

[0068] During assembly or connection, the second sealing ring 60 can come into close contact with the surface of other parts and be in a compressed state, effectively blocking the second opening 103. This ensures that impurities such as moisture and dust cannot penetrate into the interior of the power connector 00 through the second opening 103, thereby improving the overall sealing performance and protection level of the power connector 00, ensuring the safe and reliable operation of the internal conductive structure, and extending the service life of the product.

[0069] In summary, this embodiment ensures the stable positioning of the sealing ring and achieves a high-efficiency sealing effect of the second opening 103 by setting a limiting groove 17 in the second opening 103 and assembling the second sealing ring 60. It effectively solves the problems of easy detachment of the sealing ring and poor sealing performance, and achieves the technical effect of improving the sealing reliability and protection performance of the power connector 00.
