Patent number: 11372179Abstract: A connector includes a cage and a heat-radiation element. A top wall of the cage includes an opening, and first engaging structures extending from the top wall of the cage toward an outside of the cage at a periphery of the opening. The heat-radiation element is disposed on the cage corresponding to the opening, and first notches corresponding to the first engaging structures are disposed on side walls of the heat-radiation element. Each first engaging structure passes through the corresponding first notch to engage the heat-radiation element on the cage. The cage has a receiving cavity and supporting structure at a bottom of the receiving cavity. When a mating connector is inserted into the receiving cavity, a bottom of the mating connector is supported by the supporting structure, a top of the mating connector abuts against the heat-radiation element through the opening, and the heat-radiation element remains substantially stationary.Type: GrantFiled: January 5, 2021Date of Patent: June 28, 2022Assignee: DONGGUAN LUXSHARE TECHNOLOGIES CO., LTDInventors: Bai-Yu Duan, Xiao-Kai Wang, Xiao-Ping Wu

Patent number: 10287848Abstract: A seal assembly features radially stacked sealing elements separated by a ring shaped structural member with the structural member configured to fold on itself as the inner and outer sealing elements are axially compressed during the setting process. The structural member remains embedded in the outer sealing element when the assembly is set. Seal rings flank the inner and outer sealing element and feature an outwardly facing bevel to contact a conforming bevel shape on extrusion ring assemblies. During axial compression the extrusion rings are pushed out with the seal rings and then the inner and outer sealing elements are axially compressed as the structural member's ends come together and its middle folds. The structural member creates gaps to allow fluid to escape during setting.Type: GrantFiled: October 17, 2016Date of Patent: May 14, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Guijun Deng, Ping Duan, Yingqing Xu, Xiao Wang
