  • Publication number: 20240079758
    Abstract: 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.

  • Patent number: 7857666
    Abstract: An exemplary cable connector includes a terminal module, a latching flange, and a housing. The terminal module includes a first terminal, a second terminal, and an insulator. The first terminal and the second terminal are insulated by the insulator. The latching flange is fixed on an outer surface of the terminal module. The housing is fixed on a periphery of the terminal module. The latching flange forms at least one resisting surface. An inner surface of the housing defines a latching groove corresponding to the latching flange. The latching groove forms at least one resisting surface corresponding to the at least one resisting surface of the latching flange. The latching flange is latched in the latching groove.

  • Patent number: 7682201
    Abstract: 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.

  • Publication number: 20080160836
    Abstract: An exemplary cable connector plug includes a first contact, a second contact and a first insulator portion. The first contact and the second contact are insulated from each other by the first insulator portion. The second contact includes an annular contact portion, the annular contact portion surrounding the first insulator. The annular contact portion includes an anti-rotation member defined at an inner side thereof, and the insulator portion is engaged with the anti-rotation member such that the annular contact portion cannot rotate relative to the first insulator portion. The anti-rotation member of the present cable connector plug prevent or avoid the occurrence of displacement as between adjacent contacts of the cable connector plug.
