Example 1

[0055] In view of the deficiencies in the existing technology, the applicant, based on years of practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theoretical principles, has actively conducted research and innovation in order to create a technology that can solve the deficiencies in the existing technology. After continuous research, design, and repeated prototype production and improvement, this utility model with practical value has finally been created.

[0056] Please refer to Figures 1-8 This utility model provides an electrical connector, including a housing 1, a fixing member 2, an insulating base 3, two rows of terminal blocks 4, and two grounding plates 5; wherein,

[0057] The two rows of terminal groups 4 are arranged vertically at intervals to ensure that the electrical connections are clearly defined and do not interfere with each other.

[0058] Both grounding plates 5 are located between the two rows of terminal groups 4, and are located on the left and right sides of the terminal groups 4 respectively. This layout not only effectively improves the overall grounding effect and electrical safety, but also the grounding plates 5 have excellent conductivity and shielding performance, which can absorb, reflect and cancel external electromagnetic interference, thereby protecting the two rows of terminal groups 4 from the influence of electromagnetic crosstalk.

[0059] The two rows of terminal groups 4 are inserted into the insulating base 3, which not only provides the necessary support but also ensures electrical isolation and prevents short circuits.

[0060] The insulating base 3 is fixedly disposed inside the outer shell 1 by the fixing member 2. The fixing member 2 not only plays a fixing role, but also enhances the overall structural strength of the connector.

[0061] It is worth noting that the left and right sides of the fixing member 2 extend rearward and are respectively provided with first welding parts 6. These welding parts are designed to match the second welding parts 7 provided at the rear end of the grounding piece 5. Through a precise spot welding process, each first welding part 6 and its corresponding second welding part 7 achieve a firm and reliable fixed connection, thereby ensuring the continuity and stability of the grounding path.

[0062] In addition, grounding pins 8 are provided at the rear end of the grounding plate 5. These pins facilitate subsequent connection with the circuit board or other grounding structures, further enhancing the grounding performance and electrical safety of the electrical connector.

[0063] In summary, the electrical connector of this invention, through its ingenious component layout and precise manufacturing process, achieves efficient and reliable electrical connection and grounding, providing a high-quality electrical interface solution for modern electronic devices.

[0064] In one embodiment of this invention, the fastener 2 is integrally stamped, possessing high structural integrity and stability, providing solid support for its subsequent assembly and practical application;

[0065] The outer shell 1 is integrally formed with the fixing member 2 by in-mold injection molding. The connection between the two is both firm and tight, which effectively improves the overall strength and durability of the connector.

[0066] It should be noted that by employing a one-piece stamped fixing component 2 and in-mold injection molding to form the outer shell 1 and fixing component 2 into a single unit, this unique design not only significantly enhances the connector's structural strength, enabling it to withstand various harsh operating environments, but also effectively ensures excellent waterproof performance through a precise sealing structure, thereby greatly expanding the product's application areas. Furthermore, this technology also boasts significant advantages in terms of simple manufacturing, high production efficiency, and cost control. These characteristics make this connector stand out among similar products, highly competitive in the market, and very suitable for widespread promotion and application in large-scale production practices to meet the ever-growing market demand.

[0067] In one specific implementation of this embodiment, a key component, a stop block 9, is cleverly arranged inside the outer casing 1. The stop block 9 is designed with two main functional surfaces: a first stop surface 10 and a second stop surface 11, wherein the first stop surface 10 faces forward, while the second stop surface 11 faces backward.

[0068] At the same time, the insulating base 3 is given the unique design of the limiting part 12, whose front end face makes precise contact with the second stop surface 11 of the stop block 9. This design not only enhances the stability of the structure, but also ensures the accurate positioning of the insulating base 3 inside the outer shell 1.

[0069] The fastener 2, as an important element for connection and support, includes the key structure of the stop portion 201. It is worth noting that the left and right sides of the stop portion 201 also cleverly extend backward to form engaging portions 13. These engaging portions 13 can firmly engage the limiting portion 12 of the insulating base 3 between the second stop surface 11 and the engaging portions 13, thereby further enhancing the stability and reliability of the overall structure.

[0070] Even more ingeniously, the rear end face of the stop portion 201 forms a tight abutment with the first stop surface 10 of the stop block 9. This design not only restricts the possibility of the fixing member 2 moving backward, but also enhances the deformation resistance of the entire electrical connector under external force through the design of double stop surfaces, thereby ensuring the stability and durability of the electrical connection.

[0071] In summary, this embodiment, through innovative designs such as the stop block 9, the limiting part 12, the stop part 201, and the engaging part 13, not only improves the stability and reliability of the entire device, but also helps to ensure its normal operation in various usage environments.

[0072] In one specific implementation detail of this embodiment, the engaging portion 13 is carefully designed to include two parts: a connecting section 131 and an engaging section 132. This design aims to further improve the structural stability and assembly accuracy of the electrical connector.

[0073] The connecting section 131 serves as a bridge between the engaging part 13 and the stop part 201, and is arranged perpendicularly to the stop part 201. This vertical arrangement not only ensures that the connecting section 131 can be securely connected to the stop part 201, but also makes the entire structure of the fastener 2 more compact and stable.

[0074] The engaging section 132 is tightly connected to the connecting section 131 and is perpendicular to it, but parallel to the stop portion 201. This design allows the engaging section 132 to precisely engage between the limiting portion 12 of the insulating base 3 and the second stop surface 11 of the stop block 9, forming a stable fixing structure. Simultaneously, since the engaging section 132 is parallel to the stop portion 201, this also helps maintain the flatness of the entire fixing member 2, further improving the assembly accuracy and stability of the electrical connector.

[0075] In summary, through the ingenious design of the connecting section 131 and the engaging section 132, the electrical connector of this embodiment not only achieves structural stability and assembly precision, but also further enhances its reliability and durability.

[0076] In one specific implementation detail of this embodiment, the stop portion 201 has been further designed and optimized. Specifically, a clearance hole 14 is cleverly provided on the stop portion 201 for the insulating base 3 to pass through.

[0077] The clearance hole 14 is designed to ensure that the insulating base 3 can smoothly pass through the stop part 201 during installation, thereby achieving precise assembly with the housing 1 and the fastener 2. This design not only simplifies the assembly process and improves assembly efficiency, but also ensures the stability and positional accuracy of the insulating base 3 after it is fixed.

[0078] Meanwhile, the design of the clearance hole 14 also fully considers the requirements of electrical safety and structural strength. Through precise calculation and design, the size and position of the clearance hole 14 are strictly controlled within a certain range to ensure that it will not adversely affect the overall structural strength and electrical performance of the stop part 201.

[0079] In one embodiment of this invention, the protective performance of the electrical connector, particularly its waterproof performance, is further enhanced. For this purpose, a key component, a waterproof ring 15, is specifically introduced.

[0080] The waterproof ring 15 has a flexible design and can be either fitted onto the outer surface of the front end of the housing 1 or embedded in the front face of the housing 1, depending on actual needs. When the waterproof ring 15 is fitted onto the outer surface of the front end of the housing 1, it can fit tightly between the housing and the external environment, forming an effective waterproof barrier to prevent moisture from seeping in through the gaps in the housing, thereby protecting the electrical components inside the electrical connector from moisture corrosion.

[0081] When the waterproof ring 15 is embedded in the front end face of the housing 1, it can be more deeply embedded into the structure of the housing, forming a tighter bond with it. This design not only further improves the waterproof performance but also enhances the overall structural strength of the housing, improving the durability and reliability of the electrical connector.

[0082] Regardless of the installation method used, the Waterproof Ring 15 is carefully selected and rigorously tested to ensure that it has good elasticity and abrasion resistance, and can maintain a stable waterproof effect in various harsh environments.

[0083] In summary, the introduction of the waterproof ring 15 not only significantly improves the waterproof performance of the electrical connector, but also further enhances its overall structural strength and durability.

[0084] In a more detailed and innovative implementation of this embodiment, the grounding piece 5 has been further optimized, especially with the clever placement of a hole 16 at its front end.

[0085] This design is not arbitrary, but based on in-depth research and understanding of the electromagnetic shielding effect of grounding plate 5. The opening of hole 16 is intended to change the current distribution on the surface of grounding plate 5, thereby more effectively absorbing, reflecting, and canceling external electromagnetic interference. This design allows grounding plate 5 to further enhance its electromagnetic shielding effectiveness while maintaining its original anti-electromagnetic crosstalk capability, providing more robust protection for the electrical components inside the electrical connector.

[0086] Meanwhile, the opening of the holes 16 was carefully calculated and laid out to ensure that it would not adversely affect the overall structural strength and conductivity of the grounding piece 5. On the contrary, through reasonable hole design, the weight of the grounding piece 5 can be further reduced, material utilization can be improved, and production costs can be reduced while ensuring the performance of the grounding piece 5.

[0087] In summary, by incorporating the innovative design of a hole 16 at the front end of the grounding plate 5, the electrical connector in this embodiment not only further optimizes the electromagnetic shielding effect of the grounding plate but also improves material utilization and production cost efficiency.

[0088] In one specific and practical embodiment of this example, terminal group 4 is defined clearly and in detail. Specifically, terminal group 4 is not a single element, but rather a carefully arranged combination of multiple signal terminals in a parallel manner.

[0089] This design offers several advantages. First, by combining multiple signal terminals in parallel, terminal group 4 can process multiple electrical signals simultaneously, thus significantly improving the signal transmission capability and efficiency of the electrical connector. This is undoubtedly a huge advantage for modern electronic devices that need to transmit multiple data or control signals simultaneously.

[0090] Secondly, the parallel-connected signal terminals maintain good electrical isolation, avoiding interference and crosstalk between signals and ensuring the accuracy and stability of signal transmission. This is crucial for ensuring the normal operation and performance of electronic equipment.

[0091] In summary, this embodiment, by employing a terminal group 4 composed of multiple signal terminals arranged in parallel, not only improves the signal transmission capability and efficiency of the electrical connector, but also ensures the accuracy and stability of signal transmission.

[0092] Although this application frequently uses terms such as "casing" and "grounding plate," the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.

[0093] This utility model provides an electrical connector by setting two grounding plates between two rows of terminal groups arranged vertically at intervals, and setting a second welding part and a grounding pin at the rear end of the grounding plates, and setting a first welding part on the left and right sides of the fixing member used to fix and protect internal components. This allows the second welding parts of the two grounding plates to be fixedly connected to the first welding parts on the left and right sides of the fixing member by spot welding. Not only is the welding connection reliable, but the grounding pin at the rear end of the grounding plate is also not easily affected by the heat during the welding process because it is far away from the welding point, so it will not warp or deform, avoid poor solder plate encapsulation, and improve the overall performance and reliability of the connector.

[0094] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
