Abstract: A mobile phone comprising at least a phone body and an antenna is disclosed. The antenna is coupled to the phone body in a detachable manner, and the phone body further includes a circuit board. The antenna is joined with the circuit board in a manner of tenon joint or connecting, so that the electricity is connected. The antenna includes a single band, a dual band or a multi-band antenna.

Abstract: A slidably detachable mobile phone display unit, which includes a frame and an outer covering, is provided. The frame has a chamber into which a display panel is fixed whereas the outer covering is jointed to the frame in a slidably detachable way. Among which, the outer covering, which is slidably detachable from the frame, can be replaced easily; the hard and strong structure of the frame supports and protects the display panel from being damaged by hits of external sources. In addition, the frame, being small-sized, light and thin, makes it easier for the users to carry the mobile phones with them. The seamless outer covering features the integral beauty of the mobile phone.

Abstract: A mobile phone with detachable covers. The phone body has a first engaging portion and a second engaging portion, and a cover, detachably connected to the body, including a third engaging portion and a fourth engaging portion. The body and the cover are separable. The third engaging portion is fastened to the first engaging portion, and the fourth connection is fastened to the second engaging portion.

Abstract: An apparatus for seating a SIM card. The apparatus is embedded in the case of a cell phone, and includes a first plate and a second plate. The first plate includes a pair of shafts and defines a pair of parallel grooves for receiving the SIM card. The second plate includes a depressed portion to contain the first plate, wherein the depressed portion defines a pair of holes and a pair of channels connecting the pair of holes, and the pair of shafts of the first plate are slidably disposed in the pair of channels.

Abstract: A mobile phone including a covering lid, a body, a battery and a battery lid is provided according to the invention. Of which, the body is a mono-block casting with an opening section on the top, while the covering lid is coupled to the body via a first hinge such that the covering lid can be flipped to open from or flipped to close towards the body; the battery is installed inside the body and is loaded into or unloaded from the body via the opening section; the battery lid, which is installed on top of the opening section to hold the battery, is coupled to the body via a second hinge such the battery lid can also be flipped to open from or flipped to close towards the body. In practice, the battery lid can be a keypad module of the mobile phone, while the first and the second hinge can be situated at the same side either having respective axes or sharing the same axis. Moreover, the mobile phone can further include a circuit board which is installed between the battery and the body.

Abstract: The Invention describes a design of mobile phone. The design includes a phone body, a keypad module, and a covering lid. The phone body has a surface port to which the keypad module can be attached. The attachment of the keypad module secures the battery inside the phone body firmly, and thus reinforces the structural strength of the mobile phone. Different keypad modules can be attached, and thus increases the variety the phone can offer. The keypad module is connected to the main circuit board electrically through the keypad connector. The covering lid, pivoted by the cover hinge, can be rotationally moved relatively to the phone body.

Abstract: A mobile phone with a keypad supporting plate and a circuit board includes at least a subscriber identity module (SIM) card connector, wherein the SIM card connector is installed between the keypad supporting plate and the circuit board and is electrically connected to the circuit board. Moreover, such mobile phone can further include a plurality of SIM card connectors wherein these SIM card connectors are installed between the keypad supporting plate and the circuit board and are electrically connected to the circuit board. By means of control software, such mobile phone selects one SIM card connector from among several and makes the selected one enabled. In practice, a mobile phone can be equipped with a slot on its lateral side through which an SIM card can be connected to or disconnected from an SIM card connector.

Abstract: A mobile phone with base-detachable hinge structure is provided. The mobile phone compromises a base unit, a display unit, a hinge structure and a protection casing. The hinge structure, which can be attached to and detached from the base unit by means of a fixing device, is detachable from the display unit and the base unit. The design of base-detachable hinge structure in the invention facilitates the assembly and repair of the mobile phone, lest the hinge structures would be damaged during the process of disassembly resulting in discarded base units. As a result, it becomes environmentally friendly that unnecessary waste is reduced and the usefulness of the base unit improved.
