All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entirety for the purpose of disclosing and describing the Figures 1-5As shown, in an embodiment of the present utility model, a shielded connector is involved, which includes a housing 1, an electrical connection element 2, and a shielding component 3. The housing 1 is provided with a plugging cavity 11 and a fixing base 12. The fixing base 12 is provided with a terminal fixing groove 121. The electrical connection element 2 is arranged on the terminal fixing groove 121. The fixing base 12 is provided with a plugging sleeve 122, and the plugging sleeve 122 extends towards the plugging cavity 11. One end of the electrical connection element 2 extends into the plugging sleeve 122. There are multiple plugging sleeves 122, and the multiple plugging sleeves 122 are arranged in a "field" shape. The shielding component 3 includes a horizontal shielding plate 31 and a vertical shielding plate 32. Both the horizontal shielding plate 31 and the vertical shielding plate 32 are arranged in the plugging cavity 11. There are multiple vertical shielding plates 32 to separate the multiple plugging sleeves 122, and the horizontal shielding plate 31 is arranged between the multiple vertical shielding plates 32. This embodiment is used for the vehicle console to meet the functional requirements of the vehicle network signal system. The designed plugging cavity 11 and the fixing base 12 of the connector housing 1 provide a stable installation foundation for the electrical connection element 2. The terminal fixing groove 121 on the fixing base 12 precisely matches the electrical connection element 2, ensuring the stability and accuracy of the electrical connection points. At the same time, the setting of the plugging sleeve 122 not only facilitates the docking with external devices, but also its design of extending towards the plugging cavity 11 effectively protects the electrical connection element 2 from external physical damage and improves the durability of the connector. Secondly, the multiple plugging sleeves 122 are arranged in a "field" shape. This layout not only optimizes the space utilization, but also enhances the signal transmission ability and power handling ability of the connector. This arrangement enables the connector to support electrical connections of multiple channels simultaneously, meeting the requirements of complex electronic devices for high-density and high-integration connections. Moreover, the introduction of the shielding component 3 significantly enhances the electromagnetic compatibility of the connector. The horizontal shielding plate 31 and the vertical shielding plate 32 work together to build a complete shielding system in the plugging cavity 11. The vertical shielding plates 32 separate the multiple plugging sleeves 122, effectively reducing the electromagnetic interference between adjacent channels and ensuring the purity and stability of signal transmission. The horizontal shielding plate 31 further strengthens this shielding effect, especially when dealing with high-frequency signals, it can significantly reduce electromagnetic leakage and crosstalk and improve the overall electrical performance. Through reasonable structural layout and the ingenious application of the shielding component 3 in this embodiment, high reliability, high integration, and excellent electromagnetic compatibility of electrical connections are achieved. This not only improves the application performance of the connector, but also provides strong support for the miniaturization and lightweight design of modern electronic devices. In addition, this solution also has good scalability and adaptability, and can flexibly adjust the number and arrangement of the plugging sleeves 122 according to specific application scenarios to meet the customized needs of different customers.

[0026] The insertion cavity 11 has shielding fixing grooves 111 on both sides, which are used to fix the vertical shielding plate 32. The fixing base 12 has a vertical slot 123, one end of which is connected to the insertion cavity 11. The vertical shielding plate 32 is inserted into the vertical slot 123 and extends into the shielding fixing groove 111. Specifically, the vertical slot 123 has a limiting step 1231 near the shielding fixing groove 111, and the vertical shielding plate 32 has a limiting protrusion 321 at one end. The limiting protrusion 321 is used to cooperate with the limiting step 1231 to limit the vertical shielding plate within the vertical slot 123. In this embodiment, the shielding fixing grooves 111 on both sides of the insertion cavity 11 provide stable support and positioning for the vertical shielding plate 32, ensuring that the shielding plate can be accurately and firmly installed on the connector, effectively blocking external electromagnetic interference, and ensuring the purity and stability of signal transmission. Meanwhile, the vertical slot 123 designed on the mounting base 12 is connected to the insertion cavity 11, providing a convenient channel for the insertion of the vertical shielding plate 32. The vertical shielding plate 32 extends smoothly into the shielding fixing groove 111 through the slot, realizing the complete construction of the shielding structure and further enhancing the shielding effectiveness of the connector. In addition, a limiting step 1231 is cleverly set at the end of the vertical slot 123 near the shielding fixing groove 111, which cooperates with the limiting protrusion 321 at one end of the vertical shielding plate 32 to form an effective limiting mechanism. This design not only ensures the stable position of the vertical shielding plate 32 in the slot, preventing it from loosening or shifting during operation, but also greatly simplifies the installation process and improves work efficiency.

[0027] The vertical shielding plate 32 is provided with a grounding pin 322, one end of which extends to the lower side of the housing 1. In this embodiment, the extension of one end of the grounding pin 322 to the lower side of the housing 1 achieves a reliable grounding connection between the shielding plate and the connector housing 1. This structure not only simplifies the grounding operation but also greatly improves the stability and reliability of grounding. Through the grounding pin 322, static electricity and electromagnetic interference on the shielding plate can be quickly conducted to the ground, thereby effectively avoiding interference and damage to the internal circuitry of the connector. Furthermore, the combined use of the vertical shielding plate 32 and the grounding pin 322 enhances the overall protection performance of the connector. In complex and variable electromagnetic environments, this type of connector can maintain excellent anti-interference capabilities, ensuring the accuracy and stability of data transmission.

[0028] The top of the insertion cavity 11 is provided with an insertion guide groove 112, and one end of the insertion guide groove 112 is provided with a through groove 113, one end of which connects to the top of the outer shell 1. In this embodiment, the design of the insertion guide groove 112 provides a clear guide for the insertion of cables or plugs, effectively avoiding misalignment or damage caused by improper operation, thereby ensuring that the connector can maintain a stable electrical connection during use. At the same time, the through groove 113 connects to the top of the outer shell 1. This design not only facilitates the observation of the insertion status, but also provides additional operating space when needed, such as for the insertion of auxiliary tools, so as to complete the insertion operation in a tight space. In addition, this structure also helps to improve the shielding effectiveness of the connector. By reasonably designing the size and shape of the insertion guide groove 112 and the through groove 113, they can be used in conjunction with the connectors of the object.

[0029] The mounting base 12 is provided with a bending fixing groove 124, one end of which communicates with a terminal fixing groove 121. The terminal fixing groove 121 and the bending fixing groove 124 cooperate to fix the power receiving element 2. The power receiving element 2 includes a plug-in end 21, a fixing end 22, and a pin end 23. The fixing end 22 is disposed on the terminal fixing groove 121 and the bending fixing groove 124. The plug-in end 21 extends into the plug-in sleeve 122, and the pin end 23 extends to the bottom of the outer shell 1. Specifically, it also includes a pin fixing member 4. The lower side of the mounting base 12 is provided with a pin fixing step 125, which is used for mounting the pin fixing member 4. The pin fixing member 4 is provided with a pin fixing hole 41, which is used to fix the pin end 23. In this embodiment, the bending fixing groove 124 and the terminal fixing groove 121 designed on the mounting base 12 cooperate with each other to form an efficient and stable fixing mechanism for the power receiving element 2. This design not only ensures that the insertion end 21 of the power connector 2 extends precisely into the insertion sleeve 122 to achieve electrical connection, but also that its fixed end 22 is firmly locked in the terminal fixing groove 121 and the bending fixing groove 124, effectively preventing the power connector 2 from loosening or falling off due to vibration or external force. Furthermore, the pin fixing member 4 and the pin fixing step 125 further enhance the stability of the power connector 2. The pin fixing member 4 precisely positions and fixes the pin end 23 through the pin fixing hole 41, preventing deformation or displacement of the pin during long-term use, thereby ensuring the continuous stability and reliability of the connector's electrical performance.

[0030] A positioning pin 13 is provided on the lower surface of the housing 1. The positioning pin 13 is used for positioning the housing 1 during installation. A suspended step 131 is provided on the outer side of the positioning pin 13, and a suspended support strip 14 is provided on the side of the housing 1. The bottom surface of the suspended support strip 14 is flush with the bottom surface of the suspended step 131. In this embodiment, the positioning pin 13 serves as a precise installation guide element, ensuring that the housing 1 can be accurately aligned with the preset position during installation, avoiding performance degradation or connection failure caused by installation deviation. This design greatly improves the assembly efficiency and finished product quality of the connector, ensuring the reliability of the electrical connection. The suspended step 131 provided on the outer side of the positioning pin 13 not only enhances the structural strength of the positioning pin 13 but also provides an additional support surface, further stabilizing the installation state of the housing 1. In complex environments such as vibration or impact, the suspended step 131 can effectively prevent the housing 1 from loosening or shifting, ensuring the long-term stable operation of the connector. In addition, the suspended support strip 14 provided on the side of the housing 1 is flush with the bottom surface of the suspended step 131, forming a uniform and flat installation surface. This not only optimizes the connector's appearance but also enhances its adaptability and compatibility in various application environments. The presence of the suspended support bar 14 also helps to distribute the stress on the housing 1 to a certain extent, extending the connector's service life.

[0031] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
