Patent number: 11154954Abstract: The disclosure relates to the field of welding technology. A welding base includes a welding groove defined therein. A limiting member is arranged inside the welding groove for preventing solder and to-be-welded member from loosening from the welding groove after the to-be-welded member is welded to the welding joint. Based on the prior art welding base, the inside of the welding groove of the present disclosure is provided with a limiting member, which can prevent the solder from a longitudinal movement, thus preventing the solder from falling off the welding groove.Type: GrantFiled: May 23, 2017Date of Patent: October 26, 2021Assignee: COMBA TELECOM TECHNOLOGY (GUANGZHOU) LIMITEDInventors: Binlong Bu, Peitao Liu, Jianjun You, Hongbin Duan, Lijing Peng

Publication number: 20190319370Abstract: The present disclosure relates to the field of welding technology. A welding base for a microwave device includes a cavity and a welding groove defined in the cavity. An inner sidewall of the welding groove is provided with at least one solder-receiving space, and the solder-receiving space extends in an angle with an inner side of the welding groove. In the solution of the disclosure, a solder-receiving space is defined in the inner side of the welding groove, so that part of the solder enters the solder-receiving space when welding, and the solder is stuck in the solder-receiving space after the solder is hardened, and the solder is not easily peeled off.Type: ApplicationFiled: April 26, 2017Publication date: October 17, 2019Inventors: Peitao Liu, Binlong Bu, Jianjun You, Hongbin Duan, Lijing Peng
