Benefits of technology

"The present invention provides a casing for a mobile phone or terminal that seeks to improve its structure rigidity, facilitate heat transfer, and improve fixation of different parts. The casing is made of a sheet metal casing that encases the portable electronic device and is self-supporting when assembled. The cover members are U-shaped and attached to the frame unit, covering the face and side portions of the frame unit. The second cover member may embrace the frame unit completely or be supported by it. The first cover member may be insert molded onto the frame unit or attached by a snapping mechanism. The frame unit may also have means for guiding the second cover member. The casing is manufactured by 2D forming a sheet metal blank and may be made of metal sheet steel or cold rolled stainless sheet steel. The keys may be integrated in the cover members or manufactured separately. The casing improves the transfer of heat generated in the mobile terminal and fixes different parts better."

Problems solved by technology

In addition, a plastic cover is insufficiently hard and is vulnerable to cracking in collisions.
Plastic covers are usually made by injection molding, which often creates defects during manufacture.
Mechanically many of these covers have not added much to the structure of mobile terminals.
There are also difficulties with the fittings and the fixation of the different parts.
There are also limitations in manufacture covers of metal.
Usually, shapes with sharp edges are nor possible.
Therefore, the edges will be vulnerable and may fracture easily.

Abstract

A casing for a portable electronic device, comprising at least a first and a second cover member and a frame unit. The first and second cover member may be attached to the frame unit and the second cover member may enclose a part of the frame unit, wherein the casing enclose the portable electronic device and is self supporting when the first and second cover member and the frame unit are assembled.

Description

TECHNICAL FIELD[0001]The present invention relates generally to the field of casings or covers for portable electronic devices and, more particularly, to metal casings or covers for mobile terminals.BACKGROUND ART[0002]The first commercially attractive mobile phones or terminals were introduced in the market at the end of the 1980's. Since then, a lot of effort has been made in making smaller terminals, with much help from miniaturization of electronic components. Today, numerous manufacturers offer pocket-sized terminals with a wide variety of capabilities and services.[0003]In order to attract customers the terminal manufactures have therefore taken further measures to strengthen their position in the competition, one such being to offer terminals with attractive covers.[0004]Most mobile phone covers are made of plastic material, since they are easy and cheap to manufacture. In addition, a plastic cover is insufficiently hard and is vulnerable to cracking in collisions. Plastic co...
