Publication number: 20250183592Abstract: An exemplary female connector includes a female terminal having a first end for mating with a male connector or a gold finger circuit board, and a second end for connection with a PCB board. The female terminal is formed with at least one shape abruptly-changed portion between the first end and the second end. A high-frequency radiation area is formed in the vicinity of the shape abruptly-changed portion when the first end is mated with the male connector or the gold finger circuit board. A wave-absorbing material is disposed in a spatial range covered by the high-frequency radiation area. By selectively or pertinently disposing the wave-absorbing material in an area where a high-frequency radiation is likely to occur during the use of the female connector, crosstalk signals will be absorbed by the wave-absorbing material without affecting normal differential signals thereby ensuring the integrity of the differential signal.Type: ApplicationFiled: February 6, 2025Publication date: June 5, 2025Inventors: Jihai Tang, Jingqi Zhao, Yifan Xu

Publication number: 20250141156Abstract: An exemplary female connector is configured to connect to a PCB board, which is internally provided with a signal layer and a drilling hole penetrating the signal layer. The female connector includes a female terminal having two ends. The two ends include a connecting end for mating with a male connector or a gold finger circuit board, and another end forming a crimping pin to be inserted into a drilling hole and connected with the signal layer. A high-frequency radiation area is formed in the vicinity of a connection between the crimping pin and the drilling hole when the connecting end is mated with the male connector or the gold finger circuit board. A wave-absorbing material is disposed in a spatial scope covered by the high-frequency radiation area.Type: ApplicationFiled: January 3, 2025Publication date: May 1, 2025Inventors: Yifan XU, Jihai TANG, Jingqi ZHAO

Publication number: 20250141136Abstract: An exemplary female connector includes a plurality of female terminals having ends radially expanded outward to form trumpet-shaped guide heads for blind mating with a male connector or a gold finger circuit board. A first high-frequency radiation area is formed in the vicinity of the trumpet-shaped guide head when the female terminals are mated with the male connector or the gold finger circuit board. A first wave-absorbing material is disposed in a spatial scope covered by the first high-frequency radiation area.Type: ApplicationFiled: December 19, 2024Publication date: May 1, 2025Inventors: Jihai TANG, Yifan Xu, Jingqi Zhao

Patent number: 12244098Abstract: The present disclosure provides a female connector and a connector combination. The female connector includes: a female terminal having a first end for mating with a male connector or a gold finger circuit board, and a second end for connection with a PCB board, the female terminal being formed with at least one shape abruptly-changed portion between the first end and the second end, and a high-frequency radiation area being formed in the vicinity of the shape abruptly-changed portion when the first end is mated with the male connector or the gold finger circuit board; and a wave-absorbing material disposed in a spatial range covered by the high-frequency radiation area. By selectively disposing the wave-absorbing material in an area where a high-frequency radiation is easily generated during the use of the connector, crosstalk signals are absorbed, while normally transmitted electrical signals are retained, and an overall weight of the connector is light.Type: GrantFiled: December 7, 2020Date of Patent: March 4, 2025Assignee: Tianjin Laird Technologies LimitedInventors: Jihai Tang, Jingqi Zhao, Yifan Xu

Publication number: 20250030186Abstract: A female connector is configured for connection with a PCB board internally provided with a signal layer and a ground layer. A surface of the PCB board includes conductive pads connected to the signal layer and the ground layer. The female connector includes a female terminal having first and second ends. The second end includes differential signal pairs arranged at intervals and ground pins each located between an adjacent two of the differential signal pairs. The differential signal pairs are connectable to the signal layer through the conductive pads. The ground pins are connectable to the ground layer through the conductive pads. A high-frequency radiation area is in the vicinity of a joint between the differential signal pair and the conductive pad when the first end is mated with a male connector or circuit board. A wave-absorbing material is disposed in a spatial range covered by the high-frequency radiation area.Type: ApplicationFiled: October 1, 2024Publication date: January 23, 2025Inventors: Jingqi Zhao, Jihai Tang, Yifan Xu

Publication number: 20240024863Abstract: A field of environmental protection and discloses a method for preparing an amorphous silica-alumina encapsulated metal oxide catalyst and application thereof. The catalyst is prepared by filling silica-alumina precursors in tunnels of a monometallic or bimetallic complex and then performing heat treatment. The catalyst has the advantages that acidic sites and oxygen vacancies are highly dispersed, the pore size range is large and the mass transfer efficiency is high, improves the efficiency of a cracking-oxidation tandem reaction, and achieves full purification of carbon/nitrogen pollutants in landfill leachate. The COD removal rate of the landfill leachate reaches 98.3% or above, and the ammonia nitrogen removal rate thereof reaches 98.0% or above. The COD concentration of oxypyrolysis purified effluent is less than 98.7 mg/L and the ammonia nitrogen concentration thereof is less than 24.9 mg/L.Type: ApplicationFiled: June 30, 2023Publication date: January 25, 2024Applicants: NANJING TECH UNIVERSITY, NANJING RESOURCES AND ENVIRONMENT ENGINEERING TECHNOLOGY RESEARCH INSTITUTE CO., LTD.Inventors: Zhuxiu ZHANG, Xu QIAO, Tao WEI, Jihai TANG, Mifen CUI, Zihan ZHOU, Zhe ZHOU, Jinghao FAN, Xian CHEN, Zhaoyang FEI, Qing LIU
