The fixing member 3 is used to fix the power connection component 4 in the second fixing cavity 21. The mating end of the power connection component 4 extends to the mating hole 14. In this embodiment, the first fixing cavity 13 in the fixing part 11 provides a stable installation space for the fixing base 2, making the internal structure layout of the entire connector reasonable, reducing the impact of vibration and shaking on the internal components, and improving the stability of the connector during vehicle operation. The design of the mating hole 14 on the plug part 12 facilitates docking with other devices, ensuring accurate and convenient connection. The second fixing cavity 21 of the fixing base 2 corresponds to the mating hole 14, further optimizing the installation and connection of the power connection component 4. The power connection component 4 can be firmly fixed in the second fixing cavity 21 by the fixing member 3, and its mating end extends to the mating hole 14, ensuring the reliability of the power connection. In the complex electrical environment of a vehicle, stable and reliable power connection is crucial, effectively avoiding electrical faults caused by poor contact and ensuring the normal operation of the vehicle's electrical system. In the vehicle environment, vehicles face various complex operating conditions, such as high temperature, low temperature, and vibration. This structural design of the male connector enhances its environmental adaptability. The outer shell 1 provides a certain degree of protection for the internal components, preventing dust, moisture, etc. from entering and extending the service life of the connector. It also helps to improve the connector's anti-interference ability, reduce the impact of external electromagnetic interference on electrical signal transmission, and ensure the accuracy and stability of signal transmission. The use of the fixing member 3 makes the installation and removal of the power connection component 4 more convenient. This embodiment achieves various technical benefits through reasonable structural design, including stable connection, reliable power supply, strong environmental adaptability, and ease of installation and maintenance.

[0021] The outer casing 1 has a mating latch 15 located on the upper side of the plug portion 12. The mating latch 15 has a pressing portion 151, and a locking latch 152 is located at the top of the pressing portion 151 for locking the male and female connectors after mating. In this embodiment, when the male connector and the female connector are mated, the locking latch 152 securely locks them together, preventing the connectors from loosening or even falling off due to vehicle vibration. This function ensures the reliability of the vehicle's electrical system connection, avoids electrical faults caused by unstable connections, and ensures the normal operation of various vehicle electrical devices, such as in-vehicle navigation and audio systems. During installation, simply mating the male connector and the female connector will automatically lock the latch 152; when disassembly is required, the pressing portion 151 can release the lock, making the operation simple and quick. This greatly improves the efficiency of connector use and reduces the difficulty of maintenance and replacement.

[0022] The fixing part 11 has mounting springs 111 on both sides, each with a fixing groove 112. The fixing seat 2 has fixing buckles 22 on both sides, and each mounting spring 111 has a guide slope 113 at its end. The fixing buckles 22 of the fixing seat 2 are guided towards the fixing grooves 112. The fixing buckles 22 cooperate with the fixing grooves 112 to fix the fixing seat 2 in the first fixing cavity 13. In this embodiment, when the fixing seat 2 is installed into the first fixing cavity 13, the guide slope 113 guides the fixing buckles 22 of the fixing seat 2 to move towards the fixing grooves 112, making the installation process smoother and allowing for accurate alignment without complicated operations. This greatly improves installation efficiency and saves labor costs and time, which is very beneficial for large-scale production and maintenance. From the perspective of connection stability, the cooperation between the fixing buckles 22 and the fixing grooves 112 allows the fixing seat 2 to be firmly fixed in the first fixing cavity 13. During vehicle operation, strong vibrations and bumps occur. This stable fixing method prevents the mounting bracket 2 from loosening or shifting. If the mounting bracket 2 becomes loose, the connection of the power connection component 4 may be affected, potentially leading to an electrical fault. This design ensures the stability of the mounting bracket 2, thereby guaranteeing the stable connection of the power connection component 4 and improving the overall reliability of the connector in a vehicle environment.

[0023] A positioning rib 131 is provided in the first fixing cavity 13 near the plug portion 12, and a positioning groove 23 is provided at the end of the fixing seat 2. The positioning rib 131 is used to cooperate with the positioning groove 23 for positioning and assembling the fixing seat 2 within the first fixing cavity 13. In this embodiment, the design of the positioning rib 131 and the positioning groove 23 greatly improves the accuracy and convenience of assembly. When installing the fixing seat 2 into the first fixing cavity 13, the operator only needs to align the positioning groove 23 with the positioning rib 131 to quickly and accurately complete the positioning of the fixing seat 2, avoiding repeated adjustments and trial and error. This not only saves installation time and improves production efficiency, but also reduces the product defect rate caused by installation errors. During vehicle operation, vibrations and bumps will occur. If the fixing seat 2 is not installed in an accurate position, it may cause the connection between the electrical connection component 4 and other components to loosen, thereby affecting electrical performance. The cooperation between the positioning rib 131 and the positioning groove 23 ensures that the fixed seat 2 is fixed and accurate in the first fixed cavity 13, so that the power connection component 4 can be stably connected to other components, reducing connection failures caused by vibration and other factors, and ensuring the stable operation of the vehicle electrical system.

[0024] A front stop ring 141 is provided for the socket 14, a backstop block 24 is provided for the mounting base 2, and a mounting platform 41 is provided for the power connection assembly 4. The front stop ring 141 is used to abut and limit the front end of the mounting platform 41, and the backstop block 24 is used to abut and limit the rear end of the mounting platform 41. In this embodiment, when the power connection assembly 4 is installed onto the mounting base 2 and extends to the socket 14, the front end of the mounting platform 41 abuts against the front stop ring 141, and the rear end abuts against the backstop block 24. This precise limiting method ensures the accuracy of the installation position of the power connection assembly 4. This is crucial for vehicle electrical systems because an accurate installation position ensures precise docking of the power connection assembly 4 with other components, avoiding electrical connection problems caused by installation deviations and improving the overall assembly quality of the connector. Vehicles experience various complex road conditions during operation, resulting in strong vibrations and bumps. The front stop ring 141 and the back stop block 24 limit the fixed platform 41 from the front and rear ends respectively, effectively preventing the power connection assembly 4 from moving or shaking in a vibration environment. This ensures that the power connection assembly 4 maintains a stable connection state, reduces problems such as poor contact and electrical faults caused by loosening, and guarantees the stable operation of the vehicle electrical system.

[0025] The mounting base 2 is provided with a mounting slot 25, and the fixing component 3 is provided with a fixing pin 31. The fixing pin 31 is inserted into the mounting slot 25, and the fixing pin 31 is provided with an arc-shaped fixing groove 32 for fixing the power connection component 4. Specifically, the mounting base 2 is provided with connecting slots 251 on both sides of the mounting slot 25, and the fixing pin 31 is provided with connecting buckles 311. The fixing pin 31 is fixed to the connecting slots 251 by the connecting buckles 311. In this embodiment, the fixing pin 31 can be directly inserted into the mounting slot 25, making the installation process of the fixing component 3 and the mounting base 2 very convenient. Operators can quickly complete the connection between the two, greatly improving the assembly efficiency on the production line and reducing labor costs and assembly time. The arc-shaped fixing groove 32 can firmly fix the power connection component 4, holding the power connection component 4 securely in the predetermined position. During vehicle operation, strong vibrations and bumps occur. The arc-shaped fixing groove 32 prevents the electrical connection component 4 from loosening or shifting due to vibration, ensuring a stable connection between the electrical connection component 4 and other components, and guaranteeing the normal operation of the vehicle's electrical system. The engagement of the connecting slots 251 on both sides of the fixing slot 25 with the connecting buckles 311 on the fixing pin 31 further enhances the firmness of the connection between the fixing component 3 and the fixing slot 2. The connecting buckles 311 are fixed on the connecting slots 251, forming a reliable locking mechanism that prevents the fixing pin 31 from easily coming out of the fixing slot 25.

[0026] The power connection assembly 4 includes a power connection sleeve 42, an insulator 43, a power connection terminal 44, and a wiring sleeve 45. The insulator 43 is disposed inside the power connection sleeve 42, the power connection terminal 44 is disposed inside the insulator 43, and the wiring sleeve 45 is disposed at the tail end of the power connection sleeve 42. Specifically, the power connection sleeve 42 includes a front sleeve 421 and a rear sleeve 422. The front end of the front sleeve 421 extends to the mating hole 14, and the rear end extends to the first fixing cavity 13. The front end of the rear sleeve 422 is connected to the insulator 43 and the front sleeve 421, and the rear sleeve 422 is connected to the wiring sleeve 45. The mating end of the front sleeve 421 is provided with a mating spring 423, the insulator 43 is provided with a terminal fixing groove 431, and the power connection terminal 44 is disposed in the terminal fixing groove 431. In this embodiment, from an electrical performance perspective, the nested structure of the connecting sleeve 42, insulator 43, connecting terminal 44, and wiring sleeve 45 effectively ensures the stability and safety of current transmission. The insulator 43, located inside the connecting sleeve 42, prevents current leakage, avoids electrical faults such as short circuits, and ensures the normal operation of the vehicle's electrical system. The connecting terminal 44, located inside the insulator 43 and fixed by the terminal fixing slot 431, ensures the accuracy of the connecting terminal 44's position, allowing current to be transmitted stably from the connecting terminal 44, reducing resistance and signal interference, and improving power transmission efficiency. When mating with the mating hole 14, the mating spring 423 provides good elastic contact, ensuring that the connecting assembly 4 remains tightly connected to the mating hole 14 even under vibration and bumps during vehicle operation, preventing loosening and poor contact, and ensuring the reliability of the electrical connection. The design of the connecting sleeve 42, consisting of a front sleeve 421 and a rear sleeve 422, makes the installation process more flexible and convenient. The front sleeve 421 extends to the mating hole 14 and the first fixing cavity 13, and the rear sleeve 422 connects to the insulator 43, the front sleeve 421, and the wiring sleeve 45. The connections of each part are clear and easy to assemble and disassemble.
