Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] Please refer to the following: Figures 1 to 11 The present invention will now describe a DC power socket.

[0049] In one embodiment, such as Figures 1 to 5 As shown, the DC power socket includes a socket housing 1, a socket back cover 2, a flat plate 3, and a round pin 4. The socket back cover 2 is provided with a first through hole 21, and a first boss 22 and a second boss 23 that are symmetrical to each other. A recess 24 is formed between the first boss 22 and the second boss 23, and the socket back cover 2 is fixedly connected to the socket housing 1. The flat plate 3 is provided with a second through hole 31 corresponding to the first through hole 21, and a metal protrusion 32 is provided on the flat plate 3. The height of the metal protrusion 32 is less than the height of the first boss 22 and the second boss 23. The round pin 4 passes through the first through hole 21 and the second through hole 31 to fix the flat plate 3 in the recess 24, thereby realizing the fixed connection between the flat plate 3 and the socket back cover 2.

[0050] As can be seen from this embodiment, by setting the height of the metal protrusion 32 to be less than the height of the first protrusion 22 and the second protrusion 23, damage to the metal protrusion 32 can be effectively avoided during friction between adjacent DC power sockets, thus improving the stability and service life of the DC power socket. Simultaneously, the optimized fixing method between the flat plate 3 and the recessed portion 24 makes the use of this DC power socket on automated production lines more efficient, reducing production failures or shutdown alarms caused by socket overlap, friction, or damage, thereby improving production efficiency.

[0051] It should be understood that the height of the metal protrusion 32 here is less than the height of the first protrusion 22 and the second protrusion 23, that is, the overall height of the flat plate 3 is less than the height of the first protrusion 22 and the second protrusion 23.

[0052] Optionally, such as Figures 2 to 4As shown, the DC power socket also includes a bent pin 5 and a spring 6. The bent pin 5 includes a first bend 51 and a second bend 52, and the spring 6 includes an elastic body 61 and a pin 62. The bottom surface of the socket housing 1 is provided with a second opening 11, and the side surface is provided with a third opening 12. The bent pin 5 and the spring 6 are both disposed inside the socket housing 1. The pin 62 extends out of the second opening 11, the first bend 51 extends out of the third opening 12, the first surface of the second bend 52 abuts against the round pin 4, and the second surface of the second bend 52 abuts against the elastic body 61.

[0053] As can be seen from this embodiment, the configuration of the bent pin 5 and the spring 6 optimizes the performance of the DC power socket. The setting of the second opening 11 and the third opening 12 makes the components installed in a reasonable and orderly manner, improving the utilization of internal space. The contact structure between the second bend 52 and the round pin 4 and the elastic body 61 respectively enhances the stability of the electrical connection, ensures smooth current transmission, and reduces the risk of failure due to poor contact.

[0054] Optionally, such as Figure 6 As shown, a first contact protrusion 53 is provided on the first surface of the second bend 52, and the first contact protrusion 53 abuts against the circular needle 4. By providing the first contact protrusion 53 on the first surface of the second bend 52 and making the first contact protrusion 53 contact the circular needle 4, although the contact area is reduced compared to ordinary planar contact, the contact pressure is more concentrated. This allows the pressure to effectively overcome the obstacles of oxide layers or tiny impurities that may exist on the surface of the circular needle 4 during current transmission, greatly reducing contact resistance and minimizing unnecessary energy loss and heat generation at the contact point, thereby ensuring the high efficiency and stability of current transmission.

[0055] Optionally, such as Figure 7 As shown, the elastic body 61 is provided with a second contact protrusion 611, and the second surface of the second bend 52 abuts against the second contact protrusion 611. By providing the second contact protrusion 611 on the elastic body 61 and abutting the second surface of the second bend 52 against the second contact protrusion 611, the stability of current conduction is enhanced, signal fluctuations and power losses caused by poor contact are reduced, and the reliability of power supply is ensured. In addition, the protrusion contact can provide more precise positioning and support, enhance the stability of the connection between the spring 6 and the elastic body 61, and effectively buffer external force impact during insertion and removal operations, reduce component wear and displacement risks, and extend the service life of the DC power socket.

[0056] Optionally, the first bend 51 and the second bend 52 are integrally formed, as are the elastomer 61 and the pin 62. This integral forming method eliminates gaps and potential weak points between components, greatly enhancing the overall mechanical strength of the bent pin 5 and the spring 6.

[0057] Optionally, such as Figure 8 As shown, the first bend 51, the pin 62, and the flat piece 3 extend from the bottom surface of the socket housing 1 by a length of 3.00mm to 4.50mm. Preferably, the length extending from the bottom surface of the socket housing 1 can be... Specifically, the length of the bottom surface of the socket housing 1 extending outwards can be 3.45mm, 3.55mm, 3.65mm, 3.75mm, 3.80mm, 3.85mm, 3.95mm, 4.10mm, 4.15mm, 4.25mm, 4.35mm, or 4.45mm. The specific design can be tailored to product requirements and is not a limitation here. By setting the lengths of the first bend 51, pin 62, and flat plate 3 extending outwards from the bottom surface of the socket housing 1, sufficient contact stability and reliability are ensured during assembly and use of the DC power socket. This effectively prevents poor contact due to excessive length and space waste or installation difficulties due to excessive length, thus improving the overall performance and adaptability of the DC power socket.

[0058] As an example, suppose the length of the first bend 51, pin 62, and flat piece 3 extending beyond the bottom surface of the socket housing 1 is set to 3.80mm. This length ensures that the bend 5 and pin 62 can form good contact with the connecting wire or power plug outside the bottom surface of the socket, and guarantees smooth assembly and welding on automated production lines, while also avoiding design problems of being too short or too long. If the extension length is set below 3.00mm, the reliability of electrical contact may not be fully guaranteed; while if it is set above 4.50mm, the bottom surface of the DC power socket may protrude excessively, affecting its space adaptability and ease of installation. Therefore, the length range of 3.00mm to 4.50mm effectively balances electrical performance and installation space requirements, improving the stability and adaptability of the DC power socket.

[0059] Optionally, the width of the first bend 51, the pin 62, and the flat piece 3 is 2.00mm to 3.00mm. Preferably, the width of the first bend 51, the pin 62, and the flat piece 3 can be [missing information]. Specifically, the lengths of the first bend 51, the pin 62, and the flat plate 3 can be 2.30mm, 2.50mm, or 2.80mm. The specific design can be made according to product requirements and is not a limitation here.

[0060] Optionally, such as Figure 9 and Figure 10As shown, the socket back cover 2 is also provided with a connecting part 25, and the bottom surface of the socket housing 1 is provided with a groove 13 corresponding to the connecting part 25. The connecting part 25 and the groove 13 are fixedly connected. Preferably, the connecting part 25 can be designed as a insert or pin, and the groove 13 on the bottom surface of the socket housing 1 is designed to receive the insert or pin. A stable connection is achieved by inserting the connecting part 25 into the groove 13 and fixing it in place by a slot or locking device. Alternatively, the socket housing 1 and the socket back cover 2 can be fixed to the connecting part 25 and the groove 13 by rivets or other fasteners (e.g., adhesive). It should be understood that these connection methods are only examples, and specific options can be selected according to application requirements and manufacturing processes, and are not intended to limit the choice.

[0061] As can be seen from this embodiment, the fixed connection between the connecting part 25 and the groove 13 provides a more robust structural connection between the socket back cover 2 and the socket housing 1, avoiding loosening or falling off due to vibration or external force during long-term use.

[0062] Preferably, such as Figure 3 As shown, the second opening 11 can overlap with the groove 13. This design simplifies the bottom surface of the socket housing 1 by aligning the second opening 11 with the groove 13, further improving the compactness and stability of the structure. This configuration ensures that during the assembly of the DC power socket, the connecting part 25 of the socket back cover 2 and the groove 13 on the bottom surface of the socket housing 1 can align more precisely, resulting in a more stable connection, effectively reducing installation errors, ensuring precise alignment of all components, and further improving the overall reliability and service life of the DC power socket.

[0063] Optionally, such as Figure 9 and Figure 10 As shown, the socket housing 1 is provided with a third through hole 14 corresponding to the first through hole 21. The round needle 4 passes through the third through hole 14, the second through hole 31 and the first through hole 21 to fix the flat piece 3 in the recess 24.

[0064] As an example, the flat piece 3 can first be placed in the recess 24 of the socket housing 1, ensuring that the second through hole 31 of the flat piece 3 is aligned with the first through hole 21 of the socket housing 1. Then, the round needle 4 is inserted into the third through hole 14 of the socket housing 1, passing through the second through hole 31 of the flat piece 3 and the first through hole 21 of the socket back seat 1 in sequence, ensuring that the round needle 4 passes smoothly and is firmly connected to the flat piece 3. Next, a pressing tool is used to press one end of the round needle 4 into the second through hole 31 of the flat piece 3, making the connection between the round needle 4 and the flat piece 3 tighter and preventing loosening or falling off, thereby firmly fixing the flat piece 3 in the recess 24 of the socket housing 1.

[0065] Optionally, such as Figure 2 As shown, the circular pin 4 is provided with an annular protrusion 41, which abuts against the third through hole 14, and the diameter of the annular protrusion 41 is larger than the diameter of the third through hole 14. This design ensures that the annular protrusion 41 is in close contact with the inner wall of the third through hole 14 when the circular pin 4 passes through it, preventing the circular pin 4 from slipping or loosening from the third through hole 14 due to external force during installation. The larger diameter of the annular protrusion 41 further ensures a secure connection between the socket housing 1 and the socket back cover 2.

[0066] Optionally, such as Figure 5 As shown, the socket housing 1 has a cavity, and the round pin 4 is located within the cavity. This embodiment demonstrates that the cavity design ensures the connection stability and reliability of the DC power socket. When connecting electronic devices, it allows the round pin 4 to make stable contact and transmit current, thereby guaranteeing superior electrical performance.

[0067] Optionally, the height of the first boss 22 and the second boss 23 is 0.30mm~0.45mm, and the height of the metal protrusion 32 is 0.10mm~0.25mm. Preferably, the height of the first boss 22 and the second boss 23 can be... mm, specifically, it can be 0.33mm, 0.35mm, or 0.40mm; the height of the metal protrusion 32 can be... mm, specifically, can be 0.10mm, 0.15mm, or 0.20mm; none of these are limitations here.

[0068] As can be seen from this embodiment, setting the height of the first protrusion 22 and the second protrusion 23 to be higher than the height of the metal protrusion 32 helps to reduce the risk of friction and damage to the metal protrusion 32. Especially during the assembly and use of the DC power socket, it avoids unnecessary friction between the metal protrusion 32 and the adjacent DC power socket, and can reduce appearance damage caused by excessive wear while maintaining the stability of the DC power socket.

[0069] As an example, if the height of the first protrusion 22 and the second protrusion 23 in the design is 0.35mm, this provides sufficient support on the automatic feeder, preventing the socket from shifting or overlapping due to vibration, thereby improving production efficiency and stability. Meanwhile, the metal protrusion 32 has a height of 0.15mm, making it less susceptible to damage during the feeding process and preventing cosmetic damage due to excessive friction, thus improving product quality and customer satisfaction, reducing the probability of malfunctions, and extending the service life of the DC power socket.

[0070] Optionally, such as Figure 11 As shown, the length of the DC power socket is 14mm~16mm. Preferably, the length of the DC power socket can be... The diameter can be mm, specifically 14.15mm, 14.3mm, 14.45mm, 15.00mm, 15.45mm, 15.65mm, or 15.85mm. The specific diameter can be selected based on product requirements and is not a limitation here. This design ensures that the DC power socket can adapt to different types of electrical connections and installation requirements.

[0071] Optionally, such as Figure 8 As shown, the height of the DC power socket is 10.5mm~12.00mm. Preferably, the height of the DC power socket can be... Specifically, the width can be 10.90mm, 11.00mm, 11.10mm, 11.30mm, 11.40mm, 11.50mm, or 11.80mm; the width of the DC power socket is 8.5mm~10mm, preferably 9.0mm±0.1mm, specifically 8.90mm, 9.00mm, 9.10mm, 9.20mm, 9.40mm, 9.50mm, or 9.80mm. The specific dimensions can be designed according to product requirements and are not limited herein. This design effectively ensures the compatibility of the DC power socket with different electronic devices while providing sufficient space to accommodate internal components.

[0072] Optionally, the materials of the socket housing 1 and the socket back cover 2 may include PBT, PA46, PA66, PA6T, PA9T or LCP, etc. Specifically, they can be selected according to product needs, and this does not constitute a limitation.

[0073] Optionally, the flat plate 3, the round needle 4, the bent needle 5, and the material may include H62 brass, phosphor bronze, copper alloy (such as C5191), or silver-plated copper, etc. The specific selection can be made according to the application requirements and is not limited here.

[0074] The assembly process of the DC power socket of this utility model includes the following steps:

[0075] First, all components are prepared, including the socket housing 1, socket back cover 2, flat piece 3, round pin 4, bent pin 5, and spring 6. Next, the socket housing 1 is placed on the workbench of the automated equipment, and the vision positioning system is activated for a preliminary scan to ensure accurate positioning of the socket housing 1. Then, the robotic arm precisely grasps and places each component based on the information fed back by the vision system. First, the flat piece 3 is placed in the designated position on the socket housing 1, ensuring it aligns with the recess 24 inside the socket housing 1. Subsequently, the round pin 4, bent pin 5, spring 6, and other components are precisely installed into their predetermined positions in sequence. Throughout the process, the vision system continuously monitors the position and angle of each component to ensure the installation accuracy of each component and avoid deviations affecting the final power socket function. Especially when assembling the flat piece 3, the automated equipment ensures the alignment accuracy of the metal protrusion 32, the first protrusion 22, and the second protrusion 23, strictly controlling the height deviation between them to within 0.05mm. Finally, after all components are precisely installed and aligned, automated equipment presses, fixes, and seals them, ensuring a secure connection between all parts of the DC power socket and achieving the designed electrical and mechanical stability. This precise assembly process not only improves assembly efficiency and reduces manual intervention but also significantly enhances the consistency and reliability of the DC power socket's quality.
