An electronic device such as a radiotelephone (100) includes a bottom housing (108) defining a first hinge aperture (2207) and a slot (2208) adjacent the first hinge aperture. A top housing (102) defines a second hinge aperture (2223) having an inner rotation surface (2226). A shaft (2210) extends from the first housing at the first hinge aperture. The shaft is sized for insertion in the second hinge aperture and terminates in a bearing surface (2216), the inner rotation surface pivoting on the bearing surface as the second housing moves in relation to the first housing. The shaft and the bearing surface both define a shaft slot (2218) aligned with the slot in the first housing for routing a flexible circuit element (216) between the first housing and the second housing.

A foldable device (100) includes two housings (102, 108) rotatably coupled by a hinge (3800) about an axis of rotation (211). The hinge (3800) has a stationary element (3802) and a movable element (3804) positioned in a pocket (3858) of one of the housings (102, 108). The movable element (3802) is restricted to movement along the axis of rotation (211). This prevents the generation of audible clicking noises that are characteristic of existing hinge arrangements.

Hinge suitable for use in a foldable device

Conductive pads (126) of a first PCB (114) and conductive pads (128) of a second PCB (116) are electrically coupled. An electrical device includes a housing portion (112) which has an inner face (122) including a protrusive element (200). First PCB (114) has a body (203) and a flexible portion (204) which includes conductive pads (126). An elastomeric connector (208), having an elastomeric face (210) and an elastomeric edge (212), is positioned adjacent to protrusive element (200). First PCB (114) is disposed within inner face (122) of housing portion (112) such that flexible portion (204) bends, preferably at an angle perpendicular to body (203) of first PCB (114), by protrusive element (200). Flexible portion (204) is secured to elastomeric face (210), thus securing conductive layers of elastomeric connector (208) to conductive pads (126). Conductive pads (128) of second PCB (116) are abutted to elastomeric edge (212), thereby electrical coupling conductive pads (126, 128) of first and second PCBs (114, 116).

Electrical coupling method and apparatus for printed circuit boards

An uninterruptible power supply (UPS) (100) has a housing (111) that supports the major electrical components of the UPS (100), i.e., a transformer circuit (207), a switching circuit (217), and a battery (209). Furthermore, a connector (107;115;117) affixed to the housing (111 ) is capable of removably affixing the UPS (100) to an alternating-current (AC) outlet (102).

Uninterruptible power supply

A novel conductive contact comprises a dual beam spring (308, 310) which forms a 'C' shaped spring and which is used to electrically mate to a contact on a printed circuit board. The open end of the 'C' spring preferably fits over a plastic rib (404) in a housing for support. A surface mount contact (504) on the PCB has formed wings which fit into a rectangular slot in the PCB. To make electrical connection, the board is placed over the 'C' spring. The 'C' spring and plastic support protrude through the rectangular slot in the PCB. The conductive contact is preferably formed from a single piece of metal.
