[0020] The beneficial effects of the present invention are:

[0021] Compared to existing connectors, the present invention is used for vehicle-mounted connectors. Through the precise plug-in design of the board-end connector and the line-end connector, combined with the tight locking mechanism of the hook and lock assembly, it ensures the stable connection of the connector assembly in complex environments, effectively prevents accidental detachment due to vibration or external force, and ensures the continuity and efficiency of signal and power transmission. The connector assembly adopts a modular design concept. The board end and the line end are independent and have clear functions, which facilitates the rapid replacement of faulty components during equipment maintenance or upgrades, reducing maintenance costs and time. At the same time, the combined structure of the line end metal shell, power connection assembly, and inner and outer modules inside the line end is integrally formed through the injection molding process, which enhances the overall protection performance and extends the service life. The line end outer module outside the line end shell not only enhances the aesthetics, but also effectively isolates the corrosion of external moisture, dust and chemicals through injection molding technology, thereby improving the protection level of the connector and enabling it to adapt to a wider range of working environments, including humid, dusty or highly corrosive environments.

[0022] The cable-end connector utilizes both internal and external injection molding. The internal cable-end mold protects the metal housing, electrical components, and connecting wires, ensuring stability and reliability. The external mold encapsulates the connecting wires and housing, creating a single structure and ensuring durability and tensile strength during use. This addresses the stability and safety issues of existing connectors.

[0023] The wire end housing design of the present invention has a structure in which the wire end plug-in cavity and the injection molding cavity are separated and connected, which not only facilitates the installation and positioning of internal components, but also enhances the sealing and protection level of the connector through the design of the injection molding cavity, effectively prevents the external environment from corroding the internal electrical connection part, and ensures the stability and safety of the electrical connection. Secondly, the wire end metal shell, as a key structural component, firmly supports the wire end electrical component in the wire end plug-in cavity, which not only provides the necessary mechanical support, but also ensures the efficient transmission of electrical signals through its conductive properties. At the same time, the design of the wire end electrical component extending to the wire end plug-in cavity port facilitates quick and accurate docking with external equipment and reduces the plug-in and pull-out force. The wire end inner module tightly covers one end of the wire end metal shell and the connecting wire and wire end electrical component through the injection molding process. This design not only enhances the fixity of the connecting wire and prevents the risk of wire breakage due to external force pulling, but also improves the insulation performance and weather resistance of the connector and extends its service life through the selection of materials and the control of the injection molding process. The injection molding of the outer module of the wire end not only achieves comprehensive coverage of the internal components, further improving the compactness and protection capabilities of the overall structure, but also gives the connector a good appearance texture and visual effect, meeting the aesthetic requirements in different application scenarios.

The connector assembly adopts a modular design concept. The board end and the wire end are independent and have clear functions, which facilitates the rapid replacement of faulty components during equipment maintenance or upgrades, reducing maintenance costs and time. Furthermore, the integrated structure of the metal housing 4, electrical connection assembly, and internal and external modules within the terminal is achieved through an injection molding process, enhancing overall protection and extending service life.

In this embodiment, the limiting rib 311 limits the wire-end metal shell 4 in the wire-end plug-in cavity 31, effectively preventing the shell from loosening or shifting due to vibration or misoperation, thereby ensuring the stable connection and signal transmission reliability of the connector during long-term use. The bevel chamfer 312 provided at the opening of the limiting rib 311 not only optimizes the insertion path of the wire-end metal shell 4, reduces the insertion resistance, avoids scratches or jamming that may occur during the plug-in process, but also improves the user experience. It ensures the smoothness and safety of the connector during rapid plug-in and pull-out.

[0058] The wire-terminal metal shell 4 comprises an upper shell 41 and a lower shell 42. The upper and lower shells 41 and 42 interlock to form a snap-fit ​​cavity 43, one end of which is used to secure the wire-terminal electrical component 5. The lower shell 42 is provided with a contact cavity 44, one end of which communicates with the snap-fit ​​cavity 43, with one end of the wire-terminal electrical component 5 extending toward the contact cavity 44. The walls of the contact cavity 44 are provided with contact springs 441. In this embodiment, the precise snap-fit ​​mechanism of the upper and lower shells 41 and 42 not only ensures the secure formation of the snap-fit ​​cavity 43, providing a solid mounting foundation for the wire-terminal electrical component 5, but also enhances the structural strength of the connector, effectively resisting potential damage from external environmental factors such as vibration and impact. The ingenious design of the contact cavity 44 enables the wire-terminal electrical component 5 to seamlessly connect to the internal circuitry. Furthermore, the contact springs 441 arranged on the walls, through their excellent elasticity and conductivity, ensure a stable and efficient electrical connection, reducing the risk of signal attenuation or circuit breakage caused by poor contact. In addition, the adaptive characteristics of the contact spring 441 can tolerate slight deviations during the docking process to a certain extent, thereby improving the compatibility and ease of use of the connector.

[0059] Mating buckles 411 are provided on both sides of the upper shell 41, and mating slots 421 are provided on both sides of the lower shell 42. The mating buckles 411 and the mating slots 421 are engaged with each other; a fixed wire clamp 45 is provided on the rear side of the wire end metal shell 4, and the fixed wire clamp 45 fixes the connecting wire 8 by riveting. In this embodiment, by providing mating buckles 411 on both sides of the upper shell 41 and engaging with the corresponding mating slots 421 on both sides of the lower shell 42, not only the assembly process is simplified and the assembly efficiency is improved, but also the stable connection of the shell is ensured, loosening due to vibration or external force is effectively prevented, and the overall structural strength of the connector is enhanced. Secondly, the fixed wire clamp 45 design integrated on the rear side of the wire end metal shell 4 uses riveting to fix the connecting wire 8. This innovation not only improves the stability of the connecting wire 8, but also prevents the cable from falling off due to long-term use or environmental factors.

[0060] See Figures 13 to 15 As shown, the wire end electrical connection assembly 5 includes an insulating module 51 and an electrical connection element 52. The insulating module 51 includes a first fixing member 53, a second fixing member 54, and a connecting member 55. The first fixing member 53 and the second fixing member 54 are stacked one above the other. The connecting member 55 is disposed behind the first fixing member 53 and the second fixing member 54 and connects the first fixing member 53 and the second fixing member 54. Multiple electrical connection elements 52 are provided, one end of each of the electrical connection elements 52 extending toward the wire end metal shell 4 and the other end toward the connecting member 55. In this embodiment, the insulating module 51 effectively enhances the overall structural stability through the stacked structure of the first fixing member 53 and the second fixing member 54. At the same time, the connecting member 55 cleverly connects the two at their rear sides, ensuring a stable and efficient signal or current transmission path.

[0064] The wire end inner mold 6 includes an embedded portion 61 and an outer end portion 62. The wire end inner mold 6 is formed by injection molding of an insulating material. The embedded portion 61 is embedded in the injection molding cavity 32 by injection molding to cover the wire end metal shell 4, the connecting wire 8, and one end of the wire end electrical component 5. One end of the outer end portion 62 abuts the port of the injection molding cavity 32. In this embodiment, the injection molding of the insulating material ensures that the wire end inner mold 6 accurately wraps the embedded portion 61 and the outer end portion 62, effectively isolating the wire end metal shell 4, the connecting wire 8, and the wire end electrical component 5 from direct contact with the external environment, significantly enhancing the electrical insulation performance, and preventing the risk of short circuits and leakage. Secondly, the embedded portion 61 is precisely embedded in the injection molding cavity 32, tightly covering one end of the key component, which not only enhances the stability of the structure, but also improves the heat dissipation efficiency through the close combination of materials, thereby extending the service life of the connector. The outer end portion 62 precisely abuts against the port of the injection cavity 32, forming a solid barrier to prevent the intrusion of harmful substances such as external moisture and dust, thereby ensuring the purity and stability of the internal environment of the connector.

[0065] The wire end outer module 7 includes a front end portion 71 and a rear end portion 72. The injection molding cavity 32 is provided with an injection molding groove 321. The front end portion 71 is covered on the outside of the injection molding cavity 32 by injection molding to fill the injection molding groove 321 and cover the outer end portion 62. The rear end portion 72 covers the connecting wire 8. In this embodiment, the front end portion 71 tightly covers the outside of the injection molding cavity 32 through the injection molding process, which not only accurately fills the injection molding groove 321, but also enhances the structural integrity and sealing of the connector body, effectively prevents the intrusion of adverse factors such as dust and moisture in the external environment, and improves the durability and reliability of the connector. Secondly, the covering design of the front end portion 71 further strengthens the stability of the interface between the injection molding cavity 32 and the connecting wire 8, reduces the risk of loosening due to vibration or external force, and ensures the stability of signal transmission and the firmness of the connection. At the same time, this design also optimizes the appearance and texture of the connector, and enhances the overall aesthetics and market competitiveness of the product. The covering treatment of the connecting wire 8 at the rear end portion 72 not only simplifies the assembly process and reduces the number of components in the assembly process, but also provides additional mechanical protection and insulation isolation, reduces the risk of short circuit or electric shock caused by exposed wires, and ensures the safety of users.

[0066] See Figure 15As shown, a locking platform 331 is provided on the upper side of the plug connector 33 , and the locking assembly 9 is provided on the locking platform 331 . The locking member 933 is provided with a locking buckle 934 at the end thereof. In this embodiment, the design of the pressure bar 91 allows the user to trigger the locking mechanism with a simple press. This user-friendly design not only simplifies the operation process but also enhances the user experience. The limit buckle 912 on the locking groove 911 acts as a safety barrier, ensuring precise positioning and stability during the locking process, and preventing the locking member 93 from accidentally falling off or misaligning during the sliding process. The locking member 93 includes a sliding portion 931, a pushing portion 932, and a locking portion 933. The sliding portion 931 slides smoothly within the locking groove 92, ensuring the overall stability and responsiveness of the locking member 93. The pushing portion 932 acts as a power source, and through the action of an external force (such as the pressure bar 91), it pushes the locking portion 933 to move precisely within the locking groove 911, achieving a tight fit or separation between the locking buckle 934 and the target connector. The design of the locking buckle 934 can automatically adjust the locking state according to the position: when it is located at the front end of the limit buckle 912, the locking buckle 934 firmly locks the object connector, effectively preventing accidental loosening due to vibration or external force; and when it moves to the rear end of the locking buckle, it automatically enters the unlocked state, which facilitates quick separation of the connector and improves the efficiency of maintenance or replacement.

[0067] See Figure 16As shown, a method for preparing a wire end connector 20 includes the following steps: preparing a wire end electrical assembly 5, riveting an electrical connection element 52 to a fixing member, then buckling the fixing member to form the wire end electrical assembly 5, then welding a connecting wire 8, welding the connecting wire 8 to a terminal pad 521 of the electrical connection element 52, performing a solder joint inspection after welding, then wrapping a high temperature resistant insulating tape around the connecting wire 8, then assembling a wire end metal shell 4, and placing the assembled wire end electrical assembly 5 inside the wire end metal shell 4. The connecting wire 8 is fixed to the wire clamp of the wire end metal shell 4 by riveting; the prepared iron shell is then injection molded, the wire end metal shell 4 is placed in the mold, and the wire end metal shell 4, the connecting wire 8 and one end of the wire end electrical component 5 are encapsulated by injection molding. The completed injection molded structure is then assembled into the wire end shell 31, and a secondary injection molding is performed. The wire end outer module 7 is injection molded on the outside of the wire end inner module 6 to encapsulate the injection molding cavity 32 and the connecting wire 8. Finally, the locking component 9 is assembled and the finished product is tested to complete the preparation. In this embodiment, the electrical connection element 52 is tightly combined with the fixing part through a fine riveting process to form a stable wire end electrical component 5, ensuring the reliability of the electrical connection. The precise welding of the connecting wire 8 and the wiring pad 521 of the electrical connection element 52, and the subsequent solder joint inspection, further enhance the stability and safety of the electrical connection. Wrapping the connecting wire 8 with high-temperature resistant insulating tape effectively isolates the electrical risks in high-temperature environments, improving the insulation performance of the product and the safety of long-term use. The use of a metal shell 4 at the end of the cable and its riveted attachment to the connecting wire 8 not only enhances the overall strength of the structure but also provides additional physical protection. The initial injection molding process encapsulates the metal shell 4, connecting wire 8, and one end of the terminal electrical assembly 5, achieving excellent sealing and protection while also enhancing the product's appearance. The application of a secondary injection molding process to the outer module 7 further enhances the product's environmental adaptability, such as waterproofing and dustproofing, while also protecting the integrity of the internal structure. Finally, assembly of the locking assembly 9 and finished product testing ensures the final product's assembly precision and functional integrity.
