Patent number: 11604318Abstract: An optical fiber sub-assembly includes: a handle, a rear retainer, an optical cable, a field mountable connector (FMC) assembly, a spindle, and a protection hood fixedly connected to the spindle. An end of the optical cable is connected to the FMC assembly, the optical cable protrudes from a first end of the FMC assembly. The FMC assembly includes a ferrule provided at a second end of the FMC assembly. The spindle is sleeved outside the first end of the FMC assembly, and the protection hood is sleeved outside the second end of the FMC assembly. An end of the spindle that is away from the protection hood is connected to the rear retainer and is used to fasten the optical cable. The handle is sleeved outside the protection hood and the spindle.Type: GrantFiled: February 24, 2021Date of Patent: March 14, 2023Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Wei Xiong, Xiupeng Li, Jianxiong Yu, Shangjun Peng, Boyong He

Publication number: 20220252796Abstract: This application provides a pre-connector and a communications device. The pre-connector includes a connector component and an outdoor component. The connector component includes a ferrule base and a ferrule that is slidable relative to the ferrule base. The ferrule base is configured to fasten the optical cable, and the ferrule is connected to an optical fiber that is of the optical cable and that is inserted into the ferrule base. In this way, the optical fiber can be connected to the communications device by using the ferrule. The outdoor component includes: a spindle that is sleeved on the ferrule base and that is fastened to the ferrule base; and a handle sleeve sleeved on the spindle. The outdoor component is used as a connecting piece to be detachably fastened and connected to the communications device, so as to provide a locking force used when the communications device is connected.Type: ApplicationFiled: April 27, 2022Publication date: August 11, 2022Inventors: Xiupeng LI, Feng TANG, Jianxiong YU, Boyong HE

Patent number: 11394306Abstract: Provided is a dynamic control method that turns off a primary-side switching transistor when an output voltage exceeds an upper limit, and control the switching of a secondary-side synchronous rectification transistor with a fixed cycle and a fixed duty cycle. During the time that the synchronous rectification transistor is turned on, the energy of a load capacitor at the output end is extracted to the primary side, which causes the output voltage to drop rapidly and the overshoot voltage to decrease greatly.Type: GrantFiled: June 29, 2020Date of Patent: July 19, 2022Assignees: CSMC TECHNOLOGIES FAB2 CO., LTD., SOUTHEAST UNIVERSITYInventors: Shen Xu, Wei Wang, Feng Lin, Boyong He, Wei Su, Weifeng Sun, Longxing Shi

Patent number: 10921521Abstract: Embodiments provide a splice closure and a method for installing an optical cable. The splice closure includes a closure body, a cable accommodating tray, a nut component, an abutting member, and an elastic member. The abutting member is located between an optical cable and the nut component, and the elastic member is located between the optical cable and an installation tube. When the nut component is screwed to an externally threaded section of the installation tube by using threads of an internally threaded section, the abutting member abuts the elastic member, so that the elastic member elastically deforms under an abutting effect of the abutting member, so as to cause an inner circumferential wall of the elastic member that elastically deforms to abut the optical cable, and an outer circumferential wall of the elastic member that elastically deforms to abut an inner circumferential wall of the installation tube.Type: GrantFiled: March 29, 2019Date of Patent: February 16, 2021Assignee: Huawei Technologies Co., Ltd.Inventors: Guohua Pei, Boyong He

Patent number: 9391133Abstract: A capacitor and a method of fabricating thereof are provided. A structure of low pressure tetraethyl orthosilicate—low pressure silicon nitride—low pressure tetraethyl orthosilicate is used in the capacitor to replace the oxide-nitride-oxide structure of the existing capacitor; the capacitor has a relatively high unit capacitance value. Furthermore, the structure of low pressure tetraethyl orthosilicate—low pressure silicon nitride—low pressure tetraethyl orthosilicate is fabricaited by low pressure chemical vapor deposition method at relatively low temperature; thus the heat produced in the whole process is relatively low, which is insufficient to make the semiconductor device shift or make the gate metal layer or the metallized silicon layer peel off. Accordingly, the capacitor and the method of fabricating the capacitor of the present invention can be well applied in the process of the 0.5 ?m PIP capacitor or below 0.5 ?m.Type: GrantFiled: August 2, 2012Date of Patent: July 12, 2016Assignee: CSMC TECHNOLOGIES FAB1 CO., LTD.Inventors: Rengang Qin, Dejin Wang, Boyong He
