Publication number: 20240079758Abstract: An electronic device includes a metal back cover, a metal frame, and a first, second, third, and fourth radiators. The metal frame includes a discrete part and two connection parts. The connection parts are located by two sides of the discrete part, separated from the discrete part, and connected to the metal back cover. A U-shaped slot is formed between the discrete part and the metal back cover and between the discrete part and the connection parts. The first radiator is separated from the discrete part and includes a feed end. The second, third, and fourth radiators are connected to the discrete part and the metal back cover. The third radiator is located between the first and second radiators. The first radiator is located between the third and fourth radiators. The discrete part and the first, second, third, and fourth radiators form an antenna module together.Type: ApplicationFiled: August 2, 2023Publication date: March 7, 2024Applicant: PEGATRON CORPORATIONInventors: Chien-Yi Wu, Chao-Hsu Wu, Chih-Wei Liao, Hau Yuen Tan, Shih-Keng Huang, Wen-Hgin Chuang, Lin-Hsu Chiang, Chang-Hua Wu, Han-Wei Wang, Chun-Jung Hu

Patent number: 7682201Abstract: An exemplary cable connector plug (20) includes a first contact (21). The first contact includes a contact portion (210) and an extension portion (211) extending from the contact portion along an axis of the cable connector plug. The extension portion includes a first columnar portion (2111), a neck portion (2112) and a second columnar portion (2113). The neck portion interconnects the first columnar portion and the second columnar portion. A periphery of a junction where the neck portion connects with the second columnar portion is curved from a point of the periphery distal from the second columnar portion to a point of the periphery distal from the neck portion. The cable connector plug has a relatively good mechanical strength and durability.Type: GrantFiled: February 8, 2007Date of Patent: March 23, 2010Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Wu-Kuang Chen, Hsiaw-Chiang Chen, Min-Qiang Zhang, Chang-Hua Liao, Guo-Zhong Liu

The first contact includes a contact portion (210) and an extension portion (211) extending from the contact portion along an axis of the cable connector plug. The first contact further includes a hooking portion (2115) provided at the extension portion. The insulator surrounds the hooking portion, and is lockingly engaged with the hooking portion such that when the extension portion is moved along an axis of the cable connector plug, the first insulator correspondingly moves in unison with the extension portion. The cable connector plug has good mechanical strength and stability.Type: GrantFiled: February 8, 2007Date of Patent: July 29, 2008Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Wu-Kuang Chen, Hsiaw-Chiang Chen, Min-Qiang Zhang, Chang-Hua Liao, Guo-Zhong Liu
