Abstract
A mobile phone includes a phone core with operative components thereof in a one piece phone housing that is directly molded to the phone core. Operative components that require exterior access from the housing, e.g., ear speaker, microphone, loudspeaker, SIM card reader, display, and keypad, may be shielded from molding material during the molding process by shielding boxes integrally molded into the housing and/or by shielding cores in the mold of a plastic injection molding machine. A plastic injection molding machine with shielding cores may form the phone housing as an integral structure directly to and about the phone core. A method of making a mobile phone includes plastic injection molding using insert molding technique.
Claims21
A mobile wireless electronic device, comprising
- a core unit including operative components of the electronic device, and
- a molded housing directly molded to at least part of the core unit,
- wherein the core unit comprises a printed circuit board and said operative components are mounted to the printed circuit board, and
- further comprising a shielding box to protect at least an operative component during molding of the molded housing, whereby the operative component maintains its operative character during molding and
- wherein the shielding box protects at least one of a loudspeaker or vibrator.
A mobile wireless electronic device, comprising
- a core unit including operative components of the electronic device, and
- a molded housing directly molded to at least part of the core unit,
- wherein the core unit comprises a printed circuit board and said operative components are mounted to the printed circuit board, and
- wherein one of the operative components comprises keypad switches having respective pairs of switch terminals, and keypad openings in the molded housing through which force may be applied to close a circuit between respective pairs of switch terminals.
A method of making a mobile phone, comprising
- placing a phone core unit for a mobile phone in a plastic injection molding machine mold, and
- molding housing directly to the phone core unit to form an integral structure therewith, and
- wherein the phone core unit includes switch terminals for a keypad, a resilient member intended to be movable to respective positions relative to a pair of switch terminals selectively to cause completing and opening of electrical connection between the pair of switch terminals, and wherein the molding comprises urging the resilient member toward a position to cause completing of an electrical connection between a pair of switch terminals while blocking a flow path of molding material to at least part of the area of the resilient member and permitting flow of molding material to other areas in proximity to the switch terminals.
