[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0045] Please refer to Figures 1 to 8 As shown, the present invention is a USB4 and TBT4 conversion type connector, including a PCB board 1 and a connector body. The connector body includes a housing 2, a mating board 3, a middle partition board 4, a first fixing board 11 and a second fixing board 12. A plurality of middle partition boards 4 are arranged in parallel in the horizontal direction, and the plurality of middle partition boards 4 are fixedly sleeved on the same positioning board 10. This setting can reduce the crosstalk interference and common mode noise between high frequency and low frequency. The first fixing board 11 and the second fixing board 12 are respectively arranged on both sides of the positioning board 10.

[0046] Specifically, the outer shell 2 may include the monomer molecular structure of 2,6-dimethyl-4-(4'-hydroxyphenyl)-phenoxy polyphenylene ether; the monomer molecular structure of 2,6-dimethyl-4-(4'-hydroxyphenyl)-phenoxy polyphenylene ether has an electronic effect and a spatial configuration, where the methyl groups at the 2,6-positions, as alkyl substituents, due to their inductive electron-donating effect, increase the electron cloud density of the main-chain benzene ring, enhance the thermal stability of the molecule, and the steric hindrance effect of the methyl groups effectively inhibits polymer degradation, improving the aging resistance and mechanical strength; the hydroxyl group at the 4-position, as a polar functional group, conjugates with the main-chain benzene ring, and its lone pair electrons resonate with the benzene ring π-electron system, contributing to the formation of hydrogen bonds between molecules, enhancing the rigidity of the material and increasing the thermal decomposition temperature, while reducing charge accumulation and optimizing the dielectric properties; and the 4'-hydroxyphenyl is connected to the main-chain benzene ring through an ether bond, forming a rigid molecular skeleton, enabling the material to maintain stable physical and chemical properties under high-temperature conditions, reducing the dielectric loss, and reducing the energy loss during high-frequency signal transmission; in addition, the presence of the ether bond in the molecular structure of this solution also improves the chemical resistance of the molecule, enabling the product realized by this solution to still have excellent dielectric stability and mechanical strength in high-humidity and high-temperature environments; in the application of the connector outer shell in this solution, its high thermal conductivity can promote uniform heat distribution, reduce local overheating, while providing excellent electromagnetic shielding performance, ensuring the stability of high-speed data transmission, thereby effectively reducing the temperature rise caused by voltage drop and resistance inside the connector, and improving the long-term reliability and working efficiency of the device.

[0047] Specifically, the middle partition may include the monomer molecular structure of 3,4'-oxydiphenyl-1,4-benzenedicarboximide; in the monomer molecular structure of 3,4'-oxydiphenyl-1,4-benzenedicarboximide, 1,4-benzenedicarboximide is the core of the main chain, providing a highly conjugated rigid molecular skeleton, and its conjugated carbonyl group forms a strong π-π stacking effect with the benzene ring through conjugation, greatly enhancing the mechanical strength, heat resistance, and creep resistance of the product realized by this solution, while the ether bond in the 3,4'-oxydiphenyl structure imparts a certain flexibility to this solution and improves the oxidation resistance, enabling it to maintain a stable structure under high-temperature environments, while enhancing the moisture resistance and chemical stability; in addition, the carbonyl group, as a strong polar functional group, forms an inductive effect with the adjacent benzene ring, reducing the dielectric constant, enhancing the electrical insulation performance, and reducing the high-frequency signal loss; in the application of the middle partition of the connector in this solution, it can replace the traditional stainless-steel middle partition, provide good structural support, reduce the overall resistance, improve the heat dissipation efficiency, and effectively reduce signal interference, thereby optimizing the working stability and long-term reliability of the connector.

[0048] Specifically, the insertion plate 3 may include the monomer molecular structure of 6,6'-[2,2,2-trifluoro-1-(trifluoromethyl)ethylene] bis[4-(4-phenoxyphenoxy)phenol]; the monomer molecular structure of 6,6'-[2,2,2-trifluoro-1-(trifluoromethyl)ethylene] bis[4-(4-phenoxyphenoxy)phenol] serves as an insulating matrix. The highly electronegative fluorine atoms in the central structure of 2,2,2-trifluoro-1-(trifluoromethyl)ethylene reduce the electron density through a strong inductive effect, making the molecule exhibit an extremely low polarizability, thereby endowing the product represented by this solution with a high dielectric strength and an extremely low dielectric constant, ensuring that the connector in this solution has excellent electrical insulation performance and signal integrity during high-speed signal transmission; the 6,6'-bis[4-(4-phenoxyphenoxy)phenol] part provides a highly conjugated aromatic ring system, enhancing the molecular chain rigidity, improving the heat resistance stability, reducing the coefficient of thermal expansion, and ensuring that this solution will not deform due to thermal stress in a high-power working environment. At the same time, its phenoxy bridging structure enables this solution to have excellent mechanical flexibility, reduces internal mechanical stress, and enhances the impact resistance; in addition, the terminal phenolic hydroxyl groups can improve the moisture resistance and chemical stability of the polymer through hydrogen bond interactions, enabling it to maintain good dielectric properties even in a high-humidity and high-temperature environment, thereby optimizing the long-term stability of the insertion plate of the connector in this solution as an insulating matrix, and enhancing the overall heat dissipation management ability and electromagnetic shielding characteristics, ensuring that the high-speed connector can still maintain high performance and reliability during long-term operation.

[0049] The first ground terminals 8 are symmetrically inserted into the first fixing plate 11 to form a low-impedance grounding path, improving the electromagnetic shielding ability, reducing common-mode noise and electromagnetic interference; the first power terminals 9 are symmetrically inserted into the first fixing plate 11 at the position between the two first ground terminals 8 to optimize the current distribution, reduce the power supply noise, improve the power supply integrity, and ensure stable power supply; the electrical conduction terminals 6 are inserted into the first fixing plate 11 on both sides of the first power terminal 9 in an array. The differential signal optimization structure is adopted to reduce crosstalk and mode conversion loss, improve the signal integrity, and ensure the high-speed data transmission stability of USB4 and TBT4;

[0050] The second ground terminals 5 are symmetrically inserted into the second fixing plate 12 to form a low-impedance grounding shielding layer, improving the electromagnetic compatibility, reducing common-mode noise and electromagnetic interference; the second power terminals 7 are symmetrically inserted into the second fixing plate 12 at the position between the two second ground terminals 5 to optimize the current distribution, reduce the dynamic voltage fluctuation, improve the power supply integrity, and ensure stable power supply; the electrical conduction terminals 6 are inserted into the second fixing plate 12 on both sides of the second power terminal 7 in an array. The precise differential signal matching design is adopted to reduce crosstalk and mode conversion loss, improve the signal integrity, and ensure the stability of high-speed data transmission of USB4 and TBT4;

[0051] On both ends of the middle part of one side of the first fixing plate 11, positioning columns 1101 are symmetrically arranged. It is connected to the second fixing plate 12 in a sliding insertion manner to achieve precise alignment of the two fixing plates, enhance the structural stability, and prevent dislocation.

[0052] Both the first fixing plate 11 and the second fixing plate 12 are inserted into the insertion plate 3, and the insertion parts of the terminals extend to the upper and lower sides of the plug position of the insertion plate 3, ensuring the neat arrangement of the terminals, improving the contact reliability of signal transmission, and reducing the contact impedance.

[0053] The insertion plate 3 is fixedly inserted into the housing 2, and the plug position of the insertion plate 3 is arranged on one side close to the open end of the housing 2, ensuring that the terminals are aligned during connection, improving the plugging and unplugging stability, and at the same time relying on the housing to form a shielding effect to reduce electromagnetic interference.

[0054] As can be seen from the drawings, the above components constitute the basic structure of the device. The housing 2 is used for protection, the insertion plate 3 is used for the insertion of the male power terminals, the first power terminal 9 and the second power terminal 7 are used for electrical connection with the male power terminals, the first grounding terminal 8 and the second grounding terminal 5 are provided for grounding protection, and the electrical conduction terminal 6 is provided for the transmission of digital information and the like.

[0055] Please refer to Figures 5 to 8 As shown, the terminal is composed of a straight rod part and insertion parts and contact parts integrally formed on both sides of the straight line part. The contact parts of the terminal are inserted and welded on the PCB board 1 to achieve the electrical digital information transmission between the terminal and the PCB board 1.

[0056] On both side surfaces of the middle partition plate 4 between two vertically aligned first grounding terminals 8 and second grounding terminals 5, first convex strips 403 are integrally formed, and the two first convex strips 403 are respectively in contact with the insertion parts on the first grounding terminal 8 and the second grounding terminal 5. This setting can form a parallel shunt, reduce the voltage drop and internal resistance, reduce the internal temperature rise, and at the same time can reduce the crosstalk interference and common-mode noise between high frequencies.

[0057] On both side surfaces of the middle partition plate 4 between two vertically aligned first power terminals 9 and second power terminals 7, second convex strips 404 are integrally formed, and the two second convex strips 404 are respectively in contact with the insertion parts on the first power terminal 9 and the second power terminal 7. This setting can form a parallel shunt, reduce the voltage drop and internal resistance, and reduce the internal temperature rise.

[0058] The first convex strips 403 and the second convex strips 404 are respectively arranged on the two middle partition plates 4. This setting can prevent the power terminals from short-circuit burning when the tongue piece plastic wears.

[0059] The horizontal length dimension of the straight rod portion cross-section of the first ground terminal 8, the second ground terminal 5, the first power terminal 9, and the second power terminal 7 is greater than the horizontal length dimension of the insertion portion cross-section. The thickening of the straight rod portion can be used for large current transmission.

[0060] Please refer to Figure 5 and Figure 6 As shown, at both ends of the side surface of the middle partition plate 4 provided with the first rib 403 away from the conduction terminal 6, a first convex portion 401 and a second convex portion 402 are respectively provided. Both the first convex portion 401 and the second convex portion 402 extend to the outside of the insertion plate 3. The setting of the first convex portion 401 has excellent plugging and unplugging durability and stability, and the cooperation of the first convex portion 401 and the second convex portion 402 can form a good grounding circuit.

[0061] Please refer to Figure 1 , Figure 3 and Figure 4 As shown, a plurality of reinforcing feet 202 are arrayed on both outer side walls of the housing 2. The free ends of the reinforcing feet 202 are inserted and welded to the PCB board 1. This setting can improve the welding stability with the PCB board 1;

[0062] On the upper and lower side surfaces of the housing 2 near the closed end, blocking strips 201 are symmetrically arranged, and the blocking strips 201 extend towards the inside of the housing 2. The setting of the blocking strips 201 can play a role in blocking and limiting when inserting the male power supply, avoiding the collision of the male power supply with internal components and being not easily damaged;

[0063] On the upper and lower side surfaces of the housing 2 near the opening end, elastic pieces 203 are symmetrically arranged, and the elastic pieces 203 extend towards the inside of the housing 2. The setting of the elastic pieces 203 can improve the insertion stability and play a good protective role.

[0064] The PCB also has a signal equalization and retiming chip. The signal equalization and retiming chip is electrically connected to a high-speed equalization circuit module, a feed-forward equalization module, a decision feedback equalization module, a clock data recovery module, a phase-locked loop module, an error detection and correction module, a driver stage amplification module, an adjustable gain amplifier module, and a signal path selection and switching module; and the control logic is as follows:

[0065] where H EQ (f) is the high-speed equalization circuit, used for frequency domain gain to compensate for high-frequency loss; is the feed-forward equalization, used for pre-weighting signal adjustment at the transmitting end; is the decision feedback equalization, used for compensating signal distortion at the receiving end; e CDR (t) is the CDR clock data recovery, used for detecting phase error; is the CDR locked error integral, which is used to ensure clock synchronization; e PLL (t) is the PLL locked error, which is used to generate a stable clock; is the PLL control equation, which is used to adjust the phase-locked frequency through the phase error; G VGA (t) is the adjustable gain amplification, which is used to adaptively adjust the gain according to the signal quality; S sw ·P 1 +(1 - S sw )·P 2 is the signal path switching, which is used to dynamically select the best path according to the signal quality. In this solution, the signal equalization and retiming chip improves the integrity of the connector in high-speed signal transmission through the high-speed equalization circuit module, reduces the attenuation and distortion of the signal in the PCB trace, connector port and cable, and makes the signal transmission more stable; the feed-forward equalization module optimizes the signal waveform at the transmitting end through pre-compensation, reduces the inter-symbol interference, reduces the signal distortion, and improves the resolution and transmission accuracy of the signal; the decision feedback equalization module performs dynamic signal correction at the receiving end, effectively eliminates the noise and distortion in the signal transmission process, and ensures the stability of the high-speed data stream; the clock data recovery module eliminates the signal jitter through precise clock synchronization, ensures that the data is not lost or in error during high-speed transmission, and improves the signal reliability in the case of multi-device connection; the phase-locked loop module generates a stable reference clock, ensures that the connector in this solution still maintains high-precision data sampling under high-bandwidth applications, and prevents packet misalignment or decoding failure; the error detection and correction module actively detects and corrects the error bits by real-time monitoring the data stream, improves the data integrity, reduces the bit error rate, and avoids data loss, device disconnection or communication failure caused by signal damage; the driver stage amplification module adaptively adjusts the signal driving force according to different connectors, cable lengths and device environments, ensures that the receiving end can always obtain a signal with sufficient strength, and improves the compatibility and adaptability of the connector; the adjustable gain amplifier module intelligently adjusts the gain according to the signal quality, increases the signal amplitude when the signal attenuation is serious, and reduces the amplitude when the signal is overloaded, so as to prevent signal distortion, optimize the overall power management, and improve the device operation efficiency; the signal path selection and switching module automatically selects the transmission path with the least loss by real-time monitoring the signal quality, reduces the signal interference, improves the electromagnetic compatibility, and ensures that the connector in this solution can maintain the best performance in different usage environments. Therefore, the conversion connector in this solution can achieve more stable, efficient and low-power high-speed data transmission in high-performance applications such as laptop computers, data centers, external GPU expansion, 8K video transmission, Thunderbolt 4 high-speed storage devices, etc., providing a better user experience and more reliable device compatibility.
