Technical Field

[0001] This utility model relates to the field of electrical connection technology, and in particular to a vertical connector. Background Technology

[0002] With the rapid development of automotive electronics technology, in-vehicle connectors are playing an increasingly important role in various electronic systems, undertaking crucial responsibilities for signal transmission and power supply. However, in-vehicle electronic devices operate in complex environments and are inevitably affected by electromagnetic interference and electromagnetic compatibility issues, especially near high-frequency signal transmission and sensitive electronic components. Electromagnetic interference can lead to signal distortion, data errors, and even equipment malfunctions. Therefore, improving the shielding effect of in-vehicle connectors has become a critical technical problem that urgently needs to be solved.

[0003] Currently, to improve the electromagnetic shielding performance of connectors, a common approach is to equip the connector housing with a metal shielding shell. This metal shielding shell can effectively block external electromagnetic interference and ensure stable signal transmission. However, existing metal shielding shells suffer from insufficient stability in practical applications. Most metal shells are prone to deformation under vibration, temperature changes, or mechanical shock, leading to a decrease in shielding performance or even damage, thus affecting the reliability and lifespan of the connector. Therefore, there is an urgent need for a new design scheme or manufacturing technology to enhance the structural stability of the metal shielding shell and improve its resistance to deformation, thereby effectively improving the overall shielding effect and reliability of automotive connectors and meeting the high performance and high reliability requirements of modern automotive electronic systems. Utility Model Content

[0004] To solve the above problems, this utility model is a vertical connector that can avoid interference from external electromagnetic signals to the internal signal transmission of the connector, and also prevent electromagnetic signals generated inside the connector from leaking into the surrounding environment, thereby improving the anti-interference capability and signal transmission accuracy of the entire electronic system.

[0005] The technical solution adopted by this utility model is as follows: a vertical connector, including a metal shell, an insulating inner shell, and electrical terminals. The insulating inner shell is provided with a covering platform on its exterior. The insulating inner shell is provided with a mating cavity in the insertion direction. The covering platform is provided with through grooves on both sides. One end of the through groove extends into the mating cavity. One end of the through groove is provided with a limiting step. The electrical terminals are disposed in the mating cavity. The metal shell is stamped and covered onto the covering platform. The metal shell is provided with contact springs on both sides. The contact springs are provided with elastic contact parts and limiting parts. The elastic contact parts extend through the through grooves into the mating cavity to contact the connector. The limiting parts are used to abut against the limiting step to limit the elastic contact parts.

[0006] A further improvement to the above scheme is that the covering platform is disposed on the outer periphery of the insulating inner shell, and the metal outer shell is rectangularly covering the covering platform.

[0007] A further improvement to the above solution is that the end face of the insulating inner shell is provided with an end face limiting rib, which is used to limit the end face of the metal outer shell.

[0008] A further improvement to the above solution is that the covering platform is provided with a backstop groove, and the metal shell is provided with a backstop spring, the backstop spring being recessed toward the backstop groove; the backstop groove and the limiting rib fix the metal shell to the covering platform.

[0009] A further improvement to the above scheme is that the lower surface of the covering platform is provided with a positioning boss, and the metal shell is provided with a positioning groove. The positioning groove is used to cooperate with the positioning boss for positioning the metal shell.

[0010] A further improvement to the above scheme is that the metal shell is a rectangular shell formed by stamping a metal sheet, and the two ends of the metal sheet are respectively provided with a mating plate and a mating groove. The metal sheet is engaged with the mating plate and the mating groove to form a rectangular shell.

[0011] A further improvement to the above solution is that the elastic contact portion is provided with a contact protrusion facing the insertion cavity, and the contact protrusion is used to contact the target connector.

[0012] A further improvement to the above solution is that the upper and lower sides of the insertion cavity are provided with insertion guide strips and insertion guide grooves for positioning and guiding the mating connector; the left and right sides of the insertion cavity are provided with positioning guide bosses, and the limiting step is provided on the positioning guide bosses.

[0013] A further improvement to the above scheme is that a fixed panel is provided inside the insertion cavity, and a fixed slot is provided on the fixed panel. The power terminal is inserted into the fixed slot, with one end extending into the insertion cavity and the other end extending into the outside of the insulating inner shell. Multiple fixed slots are provided.

[0014] A further improvement to the above solution is that a fixing pad is provided at the rear end of the metal shell, and a fixing hole is provided on the fixing pad, and multiple fixing pads are provided.

[0015] The beneficial effects of this utility model are:

[0016] Compared to existing connectors, the insulating inner shell of this invention features a covering platform, through-slot, and limiting step that work in conjunction with other structures. The through-slot provides an installation path for the contact spring, allowing it to smoothly pass through and extend into the mating cavity to contact the target connector. The limiting step precisely limits the elastic contact portion, preventing displacement or excessive deformation of the contact spring during use, ensuring contact stability and reliability, and thus guaranteeing good conductivity of the connector. The metal shell is stamped and covered onto the covering platform, resulting in a robust connection. The metal shell also provides shielding, effectively reducing electromagnetic interference. This prevents external electromagnetic signals from interfering with the internal signal transmission of the connector and also prevents electromagnetic signals generated inside the connector from leaking into the surrounding environment, improving the anti-interference capability and signal transmission accuracy of the entire electronic system. The electrical terminals are located within the mating cavity and work in conjunction with the contact spring to achieve a stable electrical connection. The vertical design of the entire connector saves space, facilitating layout and installation in limited spaces, making it suitable for various electronic devices with high space requirements. When applied to vehicle systems, the metal housing effectively resists electromagnetic interference from vehicle equipment, ensuring stable signal transmission within the connector.

Detailed Implementation

[0024] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0025] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-6As shown, in one embodiment of this utility model, a vertical connector is provided, including a metal shell 1, an insulating inner shell 2, and a power terminal 3. The insulating inner shell 2 is provided with a covering platform 21 on its exterior. The insulating inner shell 2 is provided with a plug cavity 22 in the plugging direction. The covering platform 21 is provided with through grooves 23 on both sides. One end of the through groove 23 extends into the plug cavity 22. One end of the through groove 23 is provided with a limiting step 231. The power terminal 3 is disposed in the plug cavity 22. The metal shell 1 is stamped and covered onto the covering platform 21. The metal shell 1 is provided with contact springs 11 on both sides. The contact springs 11 are provided with elastic contact portions 111 and limiting portions 112. The elastic contact portions 111 extend through the through grooves 23 into the plug cavity 22 to contact the connector. The limiting portions 112 are used to abut against the limiting step 231 to limit the elastic contact portions 111. In this embodiment, the covering platform 21, through groove 23, and limiting step 231 of the insulating inner shell 2 are used in conjunction with other structures. The through groove 23 provides an installation path for the contact spring 11, allowing it to smoothly pass through the through groove 23 and extend to the insertion cavity 22 to contact the target connector. The limiting step 231 precisely limits the elastic contact portion 111, preventing displacement or excessive deformation of the contact spring 11 during use, ensuring contact stability and reliability, and thus ensuring good conductivity of the connector. The metal shell 1 is stamped and covered onto the covering platform 21, resulting in a robust connection. Furthermore, the metal shell 1 provides shielding, effectively reducing electromagnetic interference. This prevents external electromagnetic signals from interfering with the internal signal transmission of the connector, and also prevents electromagnetic signals generated inside the connector from leaking into the surrounding environment, improving the anti-interference capability and signal transmission accuracy of the entire electronic system. The electrical terminal 3 is located inside the insertion cavity 22 and works in conjunction with the contact spring 11 to achieve a stable electrical connection. The vertical design of the entire connector saves space and facilitates layout and installation in limited spaces, making it suitable for various electronic devices with high space requirements. In this embodiment, applied to an automotive system, the shielding effect of the metal housing 1 plays a crucial role, effectively resisting strong electromagnetic interference generated by vehicle engines, motors, and other equipment, ensuring stable signal transmission within the connector.

[0027] A covering platform 21 is disposed on the outer periphery of the insulating inner shell 2, and the metal outer shell 1 is rectangularly covered on the covering platform 21. The end face of the insulating inner shell 2 is provided with end face limiting ribs 24, which are used to limit the end face of the metal outer shell 1. Specifically, the covering platform 21 is provided with a backstop groove 211, and the metal outer shell 1 is provided with a backstop spring 12, which is recessed towards the backstop groove 211; the backstop groove 211 and the limiting ribs fix the metal outer shell 1 to the covering platform 21. In this embodiment, the metal outer shell 1 is rectangularly covered on the covering platform 21 on the outer periphery of the insulating inner shell 2. The rectangular covering method provides a tight fit, which can more effectively exert the shielding effect of the metal outer shell 1, reduce the interference of the complex electromagnetic environment of the vehicle on the internal signals of the connector, and ensure the stability and accuracy of signal transmission of various electronic systems in the vehicle. The limiting ribs on the end face of the insulating inner shell 2 provide precise end face limiting for the metal outer shell 1. During vehicle operation, various vibrations and impacts occur. The limiting ribs prevent the metal outer shell 1 from shifting in the axial direction, ensuring the relative position stability between the metal outer shell 1 and the insulating inner shell 2, thereby maintaining the overall structural stability of the connector. The anti-reverse groove 211 on the covering platform 21 cooperates with the anti-reverse spring 12 of the metal outer shell 1, further enhancing the stability of the connection. The anti-reverse spring 12 is recessed towards the anti-reverse groove 211, forming a reliable mechanical locking structure. This effectively prevents the metal outer shell 1 from detaching from the covering platform 21 when subjected to external forces, ensuring a tight connection between the metal outer shell 1 and the insulating inner shell 2 even under harsh conditions of frequent vehicle vibration and bumps. Through the dual fixation of the limiting ribs and the anti-reverse groove 211, the reliability of this vehicle connector is greatly improved, enabling it to better adapt to the complex and changing vehicle environment.

[0028] The lower surface of the covering platform 21 is provided with a positioning boss 212, and the metal shell 1 is provided with a positioning groove 13. The positioning groove 13 is used to cooperate with the positioning boss 212 for positioning of the metal shell 1. In this embodiment, the cooperation between the positioning boss 212 and the positioning groove 13 plays a role in precise positioning. The vehicle environment has extremely high requirements for the installation accuracy of components, which allows the metal shell 1 to be quickly and accurately covered on the covering platform 21. This greatly improves installation efficiency and reduces errors and time costs during the installation process. The cooperation between the positioning boss 212 and the positioning groove 13 enhances the connection stability between the metal shell 1 and the covering platform 21. During vehicle operation, strong vibrations and bumps will occur, which can effectively prevent the metal shell 1 from shifting laterally or longitudinally on the covering platform 21. It restricts the degree of freedom of the metal shell 1, making the metal shell 1 tightly connected to the insulating inner shell 2, and ensuring the stability of the overall connector structure.

[0029] The metal shell 1 is a rectangular shell formed by stamping a metal sheet. Each end of the metal sheet is provided with a mating platform 14 and a mating groove 15. The metal sheet engages with the mating platform 14 and the mating groove 15 to form the rectangular shell. In this embodiment, the stamping process is suitable for mass production, enabling efficient manufacturing of the metal shell 1 and reducing production costs. Simultaneously, the stamping process ensures the dimensional accuracy and consistency of the metal shell 1, ensuring that each produced metal shell 1 meets design requirements, facilitating subsequent assembly processes. The design of the mating platform 14 and the mating groove 15 allows the metal sheet to be easily and quickly formed into a rectangular shell. During assembly, simply engaging the mating platform 14 and the mating groove 15 completes the assembly of the metal shell 1, eliminating the need for complex welding or other connection methods, thus improving assembly efficiency. During vehicle operation, various vibrations and impacts are encountered. The tight engagement of the mating platform 14 and the mating groove 15 prevents the metal shell 1 from loosening or separating during use, ensuring the stability of its shielding effect.

[0030] The elastic contact portion 111 is provided with a contact protrusion 113 facing the insertion cavity 22. The contact protrusion 113 is used to contact the target connector. In this embodiment, the presence of the contact protrusion 113 increases the actual contact area with the target connector. In vehicle systems, electronic devices require stable power supply and signal transmission, and a larger contact area can reduce contact resistance. According to Ohm's law, reduced resistance can reduce energy loss at the contact point, reduce heat generation, and avoid connector damage or performance degradation due to overheating, thus ensuring the stable operation of vehicle electronic devices. The contact protrusion 113 can enhance the tightness of the connection with the target connector. When a vehicle is in motion, vibrations and bumps will occur. The contact protrusion 113 can increase the friction and engagement force between the two, preventing the connector from loosening or separating due to vibration, ensuring that the connector maintains a good connection state under complex road conditions, and providing a solid physical basis for the stable operation of various electronic systems in the vehicle.

[0031] The upper and lower sides of the insertion cavity 22 are provided with insertion guide strips 221 and insertion guide grooves 222 for positioning and guiding the target connector. Positioning guide bosses 223 are provided on the left and right sides of the insertion cavity 22, and limiting steps 231 are provided on the positioning guide bosses 223. In this embodiment, the design of the insertion guide strips 221 and insertion guide grooves 222 provides clear guidance for the insertion of the target connector. In the complex wiring environment of a vehicle, operators can easily and accurately insert the target connector into the insertion cavity 22 along the guide strips and guide grooves, greatly improving installation efficiency and reducing connector damage or poor connection due to misoperation during installation. The positioning guide bosses 223 can accurately determine the position of the target connector in the left-right direction.

[0032] The insertion cavity 22 has a fixing panel 224 inside, and a fixing slot 225 is provided on the fixing panel 224. The power terminal 3 is inserted into the fixing slot 225, with one end extending into the insertion cavity 22 and the other end extending into the outside of the insulating inner shell 2. Multiple fixing slots 225 are provided. In this embodiment, the fixing slots 225 provide a precise and stable installation position for the power terminal 3. The design of multiple fixing slots 225 allows for the reasonable layout of the power terminals 3 according to different circuit requirements, ensuring that each power terminal 3 is accurately in the predetermined position. This greatly improves installation efficiency, avoids confusion and errors during the installation of the power terminals 3, and makes the installation process more orderly and efficient. The fixing slots 225 tightly fix the power terminals 3, preventing them from shifting or loosening due to vibration, bumps, or other factors in a vehicle environment.

[0033] The rear end of the metal casing 1 is provided with a fixing pad 16, and the fixing pad 16 is provided with fixing solder holes 161. Multiple fixing pads 16 are provided. In this embodiment, multiple fixing pads 16 provide a reliable fixing method for the connector. By performing soldering operations in the fixing solder holes 161, the connector can be firmly installed in the corresponding circuit or device. During vehicle operation, frequent vibrations and bumps are experienced. The multiple fixing pads 16 distribute the force, effectively preventing the connector from loosening or falling off due to vibration, ensuring a stable connection in the complex vehicle environment, and guaranteeing the reliability of the entire vehicle electrical system. The fixing solder holes 161 can effectively increase the solder's grip, thereby further increasing stability.

[0034] 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.
