Description

Technical Field

[0001] This invention relates to the field of electrical connection technology, and in particular to a high-speed shielded connector. Background Technology

[0002] Against the backdrop of the rapid development of automotive intelligence and connectivity, the demand for high-speed data transmission from in-vehicle electronic systems is experiencing explosive growth. Advanced driver assistance systems, in-vehicle infotainment systems, high-resolution cameras, and radar sensors require a large amount of high-speed data exchange, placing extremely high demands on the performance of in-vehicle connectors, which act as transmission nodes. The in-vehicle environment is challenging: on the one hand, the complex electromagnetic interference generated by numerous motors, electronic control units, and high-frequency communication modules within the space seriously threatens the integrity of high-speed signals; on the other hand, the continuous vibration, impact, and harsh operating conditions such as temperature and humidity changes during vehicle operation pose severe challenges to the mechanical stability, sealing performance, and long-term reliability of connectors.

[0003] Traditional automotive high-speed connector solutions often have the following limitations: First, the shielding design is mostly a single metal shell, which is prone to problems such as incomplete shielding and leakage at high frequencies, making it difficult to effectively isolate electromagnetic interference in all directions; Second, the fixing method of the internal insulator and terminals is prone to loosening under vibration, resulting in increased contact resistance or even signal interruption; Third, the stress relief design of the cable is insufficient, and external force can be directly transmitted to the crimping points of the conductive terminals, posing a risk of connection failure; Fourth, the overall structure is often relatively complex, with many assembly processes, low production efficiency, difficulty in ensuring consistency, and high cost. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides comprehensive electromagnetic shielding for the conductive terminals and the inner core connection points of the connecting wires, effectively isolating the mutual interference between the internal high-speed signals and the external complex electromagnetic environment, thus ensuring the signal integrity of the high-speed shielded connector.

[0005] The technical solution adopted in this invention is as follows: a high-speed shielded connector, comprising an injection-molded outer shell, a first shielded lower shell, a second shielded lower shell, a shielded upper cover, an insulating base, conductive terminals, and connecting wires. The first shielded lower shell, the second shielded lower shell, and the shielded upper cover constitute a shielded housing. The injection-molded outer shell is provided with a fixing cavity for fixing the shielded housing, and the insertion end of the shielded housing is exposed outside the fixing cavity. The first shielded lower shell has an open cavity, and connecting plates are provided on both sides of the open cavity. The second shielded lower shell is disposed in the open cavity and is connected to the connecting plates on both sides. The shielded upper cover covers the upper side of the open cavity and is connected to the connecting plates on both sides to close the open cavity and form a shielded cavity. One end of the insulating base is disposed in the shielded cavity. The insulating base is provided with multiple terminal fixing slots along the insertion direction. The conductive terminals are disposed in the terminal fixing slots. The tail of the injection-molded outer shell is used to fix the connecting wires, and the inner core of the connecting wires is used to pass through the shielded housing and connect to the conductive terminals.

[0006] A further improvement to the above solution is that the wiring terminal of the injection-molded shell is provided with a lead wire sleeve, which is used to pass through the connecting wire; injection-molded slots are provided on both sides of the fixing cavity, and fixing buckles are provided on both sides of the first shielding lower shell, which are used to cooperate with the injection-molded slots to fix the shielding shell in the fixing cavity.

[0007] A further improvement to the above solution is that an extension block is provided at the upper end of the injection-molded housing, the end of the extension block extends to the panel of the insulating base and is connected to the panel, the extension block is provided with a pressing buckle, the pressing buckle is used for locking when the connector is inserted; the tail of the pressing buckle is provided with a pressing part, and limit guards extend from both sides of the injection-molded housing to limit the pressing part.

[0008] A further improvement to the above solution is that a wire clamp is provided at the tail of the first shielding lower shell, and the wire clamp is provided with a riveting part, which is used to rivet the connecting wire to fix the connecting wire.

[0009] A further improvement to the above solution is that the connecting plate is provided with a first connecting slot and a second connecting slot, the second shielding lower shell is provided with a first connecting buckle, and the shielding upper cover is provided with a second connecting buckle. The first connecting buckle is used to cooperate with the first connecting slot to fix the second shielding lower shell on the first shielding lower shell, and the second connecting buckle is used to cooperate with the second connecting buckle to fix the shielding upper cover on the first shielding lower shell to cover the open cavity.

[0010] A further improvement to the above solution is that the front end of the connecting plate is provided with an assembly buckle, and the two sides of the insulating seat are provided with assembly slots. The assembly buckle is used to cooperate with the assembly slots to fix the insulating seat in the shielding cavity. The connecting plate is provided with a folding part on one side of the assembly buckle. The folding part forms a slot with the bottom surface of the open cavity. The two sides of the insulating seat are provided with insertion parts. The slot is used to cooperate with the insertion parts and tightly fit the insertion parts.

[0011] A further improvement to the above scheme is that the second shielding lower shell is provided with an inner core guide groove, which is used to guide the inner core of the connecting wire toward the terminal fixing groove of the insulating seat. Multiple inner core guide grooves are provided, and partitions are provided between the multiple inner core guide grooves for separation. The shielding upper cover is provided with an elastic pressure plate, the end of which faces the inner core guide groove and is used to press the inner core of the connecting wire into the inner core guide groove.

[0012] A further improvement to the above scheme is that the insulating base is provided with a plug-in groove in the plugging direction, and the end of the shielding cover is provided with a plug-in pin. One end of the plug-in pin is inserted into the plug-in groove to fix the insulating base in the shielding cavity.

[0013] A further improvement to the above solution is that the end of the insulating base is provided with a panel, the panel is provided with a plurality of insertion holes that match the terminal fixing groove, and the opening of the insertion hole is provided with a guide slope.

[0014] A further improvement to the above solution is that the surface of the insulating base is provided with a terminal slot, one end of the terminal slot is connected to the terminal fixing slot, the terminal slot is provided with a terminal buckle, and the terminal buckle is used to fix the conductive terminal in the terminal fixing slot.

[0015] The beneficial effects of this invention are:

[0016] Compared to existing connectors, this invention employs a dual structure of an injection-molded outer shell and a metal shielding shell. The internal shielding shell (composed of a first lower shielding shell, a second lower shielding shell, and a shielding top cover) forms a complete, enclosed Faraday cage, providing 360° electromagnetic shielding for the conductive terminals and the inner core connection points of the connecting wires. This effectively isolates the internal high-speed signals from the complex external electromagnetic environment, ensuring signal integrity. The external injection-molded shell not only provides insulation and protection, but its covering structure further enhances the overall mechanical strength and sealing performance, while also forming a second protective barrier, improving the overall resistance to external mechanical shocks and environmental corrosion. This dual protection enhances the connector's long-term operational reliability in automotive environments filled with electromagnetic interference, vibration, and harsh weather conditions. As an independent pre-assembled module, the shielding shell allows for the prior assembly of all precision conductive components (insulating bases, conductive terminals) and the construction of the shielding structure, ensuring the assembly quality and shielding effectiveness of the internal core components. Subsequently, this module is embedded into the fixing cavity of the injection-molded shell for injection molding or fixation. By breaking down the complex assembly process, the assembly steps of the final product are simplified, which facilitates automated production and improves production efficiency and product consistency. Simultaneously, the injection molding process ensures that the shielding shell is firmly and precisely fixed in the designated position, preventing internal loosening and guaranteeing high precision and stability. The injection-molded shell directly serves to fix the connecting cable at the rear, providing excellent stress relief. It effectively distributes the tensile and torsional forces on the cable to the robust shell, preventing external forces from being directly transmitted to the internal termination points and avoiding wire breakage or loosening due to long-term vehicle vibration. The inner core of the connecting cable passes through the shielding shell before connecting to the conductive terminals, ensuring that the signal is under full shielding protection throughout its journey into the connector core, preventing electromagnetic leakage and improving overall electromagnetic compatibility performance. This meets the stringent requirements of automotive connectors for high vibration resistance, high reliability, and long lifespan. Attached Figure Description

[0020] 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.

[0021] 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 in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] like Figures 1-4As shown, in one embodiment of the present invention, a high-speed shielded connector is provided, including an injection-molded outer shell 1, a first shielded lower shell 2, a second shielded lower shell 3, a shielded upper cover 4, an insulating base 5, conductive terminals 6, and connecting wires 7. The first shielded lower shell 2, the second shielded lower shell 3, and the shielded upper cover 4 form a shielded housing. The injection-molded outer shell 1 is provided with a fixing cavity 11, which is used to fix the shielded housing. The insertion end of the shielded housing is exposed outside the fixing cavity 11. The first shielded lower shell 2 has an open cavity 21, and connecting plates are provided on both sides of the open cavity 21. 22. The second shielding lower shell 3 is disposed within the open cavity 21 and connected to the connecting upright plate 22 on both sides. The shielding upper cover 4 covers the upper side of the open cavity 21 and is connected to the connecting upright plate 22 on both sides to close the open cavity 21, forming a shielding cavity. One end of the insulating seat 5 is disposed within the shielding cavity. The insulating seat 5 is provided with multiple terminal fixing slots 51 along the insertion direction. The conductive terminal 6 is disposed within the terminal fixing slots 51. The tail of the injection-molded shell 1 is used to fix the connecting wire 7, and the inner core of the connecting wire 7 is used to pass through the shielding shell and connect to the conductive terminal 6. This embodiment adopts a dual structure of injection-molded shell 1 and metal shielding shell. The internal shielding shell (composed of the first shielding lower shell 2, the second shielding lower shell 3, and the shielding upper cover 4) constitutes a complete and closed Faraday cage, providing 360° electromagnetic shielding for the connection point of the conductive terminal 6 and the inner core of the connecting wire 7, effectively isolating the mutual interference between the internal high-speed signal and the external complex electromagnetic environment, and ensuring signal integrity. The outer injection-molded housing 1 not only provides insulation and protection, but its covering structure further enhances the overall mechanical strength and sealing performance, while also forming a second protective barrier, improving the overall resistance to external mechanical impact and environmental corrosion. This dual protection improves the long-term operational reliability of the connector in automotive environments filled with electromagnetic interference, vibration, and harsh weather conditions. As an independent pre-assembled module, the shielding housing allows for the prior assembly of all precision conductive components (insulating base 5, conductive terminals 6) and the construction of the shielding structure, ensuring the assembly quality and shielding effectiveness of the internal core components. Subsequently, this module is embedded into the fixing cavity 11 of the injection-molded housing 1 for injection molding or fixation. Decomposing the complex assembly process simplifies the final product assembly steps, facilitating automated production and improving production efficiency and product consistency. Simultaneously, the injection molding process ensures that the shielding housing is firmly and precisely fixed in the designated position, preventing internal loosening and guaranteeing the product's high precision and stability. The injection-molded housing 1 directly serves to fix the connecting wire 7 at the rear, providing excellent stress relief. It can effectively distribute the tensile and torsional forces on the cable to the robust housing, preventing external forces from being directly transmitted to the internal termination points and avoiding wire core breakage or loosening of connections caused by long-term vehicle vibration.The inner core of the connecting wire 7 passes through the shielding shell before connecting to the conductive terminal 6, ensuring that the signal is under shielding protection throughout its journey into the core of the connector, preventing electromagnetic leakage and improving overall electromagnetic compatibility performance. This meets the stringent requirements of automotive connectors for high vibration resistance, high reliability, and long lifespan.

[0023] The injection-molded housing 1 has a lead sleeve 12 at its terminal, which is used to pass through the connecting wire 7. The fixed cavity 11 has injection-molded slots 111 on both sides, and the first shielding lower shell 2 has fixing buckles 23 on both sides. The fixing buckles 23 cooperate with the injection-molded slots 111 to fix the shielding housing within the fixed cavity 11. This embodiment provides a smooth transition channel and protection for the connecting wire 7 through the lead sleeve 12 structure, avoiding insulation wear caused by sharp-angle bending or friction at the cable exit, thus improving cable durability. The cooperation between the fixing buckles 23 and the injection-molded slots 111 achieves precise positioning of the metal shielding housing within the injection-molded housing 1. This ensures that the shielding module will not shift or loosen within the housing when subjected to vibration and insertion / extraction forces, guaranteeing the overall structural integrity and reliability of the product, and meeting the high vibration resistance requirements of automotive connectors.

[0024] An extension block 13 is provided at the upper end of the injection-molded housing 1. The end of the extension block 13 extends to the panel 55 of the insulating base 5 and connects to the panel. The extension block 13 is provided with a pressing buckle 131, which is used for locking the connector during mating. A pressing part 132 is provided at the tail of the pressing buckle 131. Limiting guard plates 14 extend from both sides of the injection-molded housing 1 to limit the pressing part 132. In this embodiment, the pressing buckle 131 mechanism is integrated into the extension block 13 of the injection-molded housing 1, and its end is connected to the panel of the insulating base 5. This ensures that the operating force of the buckling mechanism directly acts on the core structure of the entire connector, enhancing the strength and stability of the lock. The limiting guard plates 14 limit the stroke of the pressing part 132, preventing damage to the buckling mechanism due to excessive pressing, improving the reliability of operation and service life. Reliable locking is achieved, preventing the connector from accidentally disengaging during vehicle vibration and ensuring the continuity of electrical connection. The end of the extension block 13 is provided with a mounting insert 133, and the panel 55 is provided with a groove 553, wherein the mounting insert 133 is embedded in the groove 553.

[0025] A wire clamp 24 is provided at the tail of the first shielding lower shell 2. The wire clamp 24 is provided with a riveting part 241, which is used to rivet the connecting wire 7 to fix the connecting wire 7. In this embodiment, the cable is fixed by riveting inside the shielding shell. The strong mechanical connection generated by riveting can directly transmit the tensile and torsional forces on the cable to the robust metal first shielding lower shell 2, effectively avoiding the transmission of external forces to the fragile conductive terminal 6 and the crimping point of the wire core, preventing fatigue fracture of the terminal point caused by long-term vehicle vibration, and greatly improving the long-term reliability of the electrical connection under harsh working conditions.

[0026] The connecting plate 22 is provided with a first connecting slot 221 and a second connecting slot 222. The second shielding lower shell 3 is provided with a first connecting buckle 31, and the shielding upper cover 4 is provided with a second connecting buckle 41. The first connecting buckle 31 is used to cooperate with the first connecting slot 221 to fix the second shielding lower shell 3 onto the first shielding lower shell 2. The second connecting buckle 41 is used to cooperate with the second connecting slot 222 to fix the shielding upper cover 4 onto the first shielding lower shell 2, thereby covering the open cavity 21. This embodiment achieves rapid assembly between various metal shielding components through multiple sets of buckles and slots, simplifying the process and improving production efficiency. More importantly, the direct mechanical snap-fit ​​between the metal parts ensures good electrical contact continuity between the shielding components, forming a complete and low-impedance shield, preventing electromagnetic waves from leaking from the component joints, and ensuring the stability of the overall shielding effectiveness.

[0027] The front end of the connecting plate 22 is provided with an assembly buckle 223, and the two sides of the insulating seat 5 are provided with assembly slots 52. The assembly buckle 223 is used to cooperate with the assembly slots 52 to fix the insulating seat 5 in the shielding cavity. The connecting plate 22 is provided with a folding part 224 on one side of the assembly buckle 223. The folding part 224 and the bottom surface of the open cavity 21 form a slot 225. The two sides of the insulating seat 5 are provided with insertion parts 53. The slot 225 is used to cooperate with the insertion parts 53 and tightly fit the insertion parts 53. In this embodiment, the initial fixation of the insulating seat 5 in the shielding cavity is achieved by the cooperation of the assembly buckle 223 and the assembly slots 52. The combination of the slot 225 formed by the folding part 224 and the tight fit of the insertion parts 53 constitutes a multi-point limiting of the insulating seat 5. The combination of snap-fit ​​and tight-fitting fixing enhances the stability of the insulating base 5 within the cavity, effectively suppressing its minute displacement in all directions under vibration, ensuring that the conductive terminals 6 inside always maintain extremely high positional accuracy, thereby guaranteeing reliability and consistency when mating with the connector.

[0028] The second shielding lower shell 3 is provided with an inner core guide groove 32. The inner core guide groove 32 guides the inner core of the connecting wire 7 toward the terminal fixing groove 51 of the insulating seat 5. Multiple inner core guide grooves 32 are provided, and partitions 33 are provided between them for separation. The shielding upper cover 4 is provided with an elastic pressure plate 42, the end of which faces the inner core guide groove 32, and is used to press the inner core of the connecting wire 7 into the inner core guide groove 32. In this embodiment, the inner core guide groove 32 and the partitions 33 achieve orderly branching and management of multiple wire cores, accurately guiding each wire core to the corresponding terminal fixing groove 51, avoiding misalignment, crossing, and tangling, facilitating termination operations, and reducing signal crosstalk. The elastic pressure plate 42 provides downward pressure during assembly, temporarily fixing the wire core in the guide groove to prevent it from coming out midway, ensuring smooth assembly and accurate termination position, and improving production yield and efficiency.

[0029] The insulating base 5 has a insertion groove 54 in the insertion direction, and the end of the shielding cover 4 has an insertion pin 43. One end of the insertion pin 43 is inserted into the insertion groove 54 to fix the insulating base 5 in the shielding cavity. In this embodiment, the insertion pin 43 of the shielding cover 4 cooperates with the insertion groove 54 of the insulating base 5 to provide a fixing point from the front end of the insulating base 5. Combined with the side snap-fit ​​fixing, a more stable "three-point" fixing structure is formed, which enhances the insulating base 5's resistance to front end lifting and overall loosening, ensuring that the insulating base 5 and terminals will not move backward or shake due to force when frequently plugging and unplugging the connector, thus improving the product's mechanical durability and plugging / unplugging life.

[0030] An insulating base 5 has a panel 55 at its end, which has multiple insertion holes 551 that match the terminal fixing slots 51. The openings of the insertion holes 551 are provided with guide bevels 552. In this embodiment, the panel 55 structure enhances the overall strength of the end of the insulating base 5. The insertion holes 551 ensure that the conductive terminals 6 can be accurately exposed for mating. The guide bevels 552 automatically guide the male connector pins smoothly into the insertion holes 551 when mating with the male connector, achieving blind mating, reducing the difficulty of insertion and removal and alignment requirements, effectively preventing terminal damage due to alignment deviations, improving user experience and connector durability.

[0031] The surface of the insulating base 5 is provided with a terminal slot 56, one end of which is connected to a terminal fixing slot 51. The terminal slot 56 is provided with a terminal latch 561, which is used to fix the conductive terminal 6 within the terminal fixing slot 51. This embodiment provides a locking function for the conductive terminal 6 by integrating the terminal latch 561 structure onto the insulating base 5. When the terminal is inserted into the terminal fixing slot 51 from the rear, the corresponding structure on the terminal is reliably locked by this latch, preventing the terminal from accidentally coming out of the fixing slot due to vibration or cable pulling. This ensures absolute stability of the electrical connection under extreme operating conditions and fully meets the stringent safety standards of the automotive industry for components.

[0032] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
