Abstract:
A handheld electronic device may be provided that contains a conductive housing and other conductive elements. Transceiver circuitry, such as radio frequency (RF) transceiver circuitry configured to transmit and receive RF signals, may be connected to the resonating elements by transmission lines such as coaxial cables. The electronic device may have an integrated touch screen display in which a user can control the device by interacting directly with the display.
Abstract:
An array of electrical components may be mounted in openings in an electronic device housing. The housing may have a cylindrical shape or other curved shape. A support structure such as a hollow cylindrical tube may be mounted within the interior of the housing. The electrical components may have terminals that mate with corresponding contacts on a flexible printed circuit. Interconnect paths on the flexible printed circuit may be used to route signals for the electrical components. The flexible printed circuit may be wrapped into the shape of a cylindrical tube and may be mounted on an interior surface of the cylindrical housing or on the exterior surface of the support structure.
Abstract:
An array of electrical components may be mounted in openings in an electronic device housing. Gaskets may be used to seal the electrical components to a housing wall. The housing wall may be planar or may have a cylindrical shape or other curved shape. The electrical components may be mounted to the housing wall using screws and nuts. Each nut may have a central member with opposing stops at the ends of the central member. An opening in each central member may receive a screw to allow the nut to rotate between an installation position and a locked position. The openings in the housing wall may have scalloped extensions that allow the nuts to clear the housing wall while the components are being inserted into the housing. Following installation, the nuts may be rotated into the locked positions.
Abstract:
An electronic device may have a rigid support structure to which electrical components are mounted. The rigid support structure may be an electronic device housing structure such as a housing wall having openings that receive the electrical components. The electrical components may have electrical component connectors. A printed circuit board may be used to convey signals for the electrical components. Connectors may be mounted to the printed circuit board. Lateral shift accommodation structures may be formed between the electrical component connectors and the electrical components or in the vicinity of the connectors on the printed circuit to allow the connectors on the printed circuit to mate with the electrical component connectors of the rigidly mounted electrical components.
Abstract:
Portable electronic devices are provided. Each device may be formed from two parts. A first part may be provided with components such as a display, a touch screen, a cover glass, and a frame. A second part may be provided with a plastic housing, circuit boards containing electrical components, and a bezel. Engagement members may be connected to the first and second parts. The engagement members may be formed from metal clips with holes and springs with flexible spring prongs that mate with the holes in the clips. The metal clips may be welded to frame struts on the frame and the springs may be welded to the bezel. During assembly, the first part may be rotated into place within the second part. Retention clips attached to the frame may be used to secure the two parts together. Assembly instructions and associated connector numbers may be provided within the devices.
Abstract:
A handheld electronic device may be provided that contains a conductive housing and other conductive elements. The conductive elements may form an antenna ground plane. One or more antennas for the handheld electronic device may be formed from the ground plane and one or more associated antenna resonating elements. Transceiver circuitry may be connected to the resonating elements by transmission lines such as coaxial cables. Ferrules may be crimped to the coaxial cables. A bracket with extending members may be crimped over the ferrules to ground the coaxial cables to the housing and other conductive elements in the ground plane. The ground plane may contain an antenna slot. A dock connector and flex circuit may overlap the slot in a way that does not affect the resonant frequency of the slot. Electrical components may be isolated from the antenna using isolation elements such as inductors and resistors.
