The present invention relates to a part key for switching the function of a communication device such as a mobile phone, PDA, MP3, etc. More specifically, the appearance is clean and the surface peeling does not occur is used to cope with the plating key made of synthetic resin By improving the structure of the metal parts key so that light leaks out from the back side, it is easy to select and use the parts key to be selected at night or in the dark, and at the same time, mass production and production by simplifying the manufacturing process of the metal parts key. Not only to reduce costs, but also to realize a variety of colors through the printing film and to maintain the feel of the metal material as it is designed to increase the product value through the parts key.

In general, electronic products such as mobile phones, MP3s, and PDAs have various component keys to enable the function switching.

In addition to the key button having a dial function for making a phone call, the parts key includes a navigation key including a function key for navigating a menu function, a volume key for adjusting a volume, and a camera key and an electric phone in a mobile phone having a camera function. For example, a button key that transmits a signal, and a speaker decoy and a hinge decoy for design or decoration purposes.

The above-described part keys are combined parts that are coupled to electronic products (portable communication devices), and are formed to have a three-dimensional shape so as to give a shape and a three-dimensional effect according to the shape of the counterpart (body), as well as functions. According to (role), a projection for pressing a metal dome or switch is formed on the bottom surface.

Part keys formed as described above are popularized with component keys made of synthetic resins that are easy to shape and easy to mass produce.

The injection part key made of the synthetic resin is first molded into a shape suitable for the function using an injection molding machine.

As described above, the injection molded part key formed by injection molding is surface-treated, and then the injection part key is completed by adding a rubber series such as silicone or urethane to have a projection for pressing a metal dome or a switch on the bottom surface.

The reason for the surface treatment of the surface of the injection molded part key manufactured as described above has a primary purpose to protect the surface of the molded injection part key, and a secondary purpose of pursuing differentiation of the design through color.

 As described above, the surface treatment of the injection-molded component key is mainly selected by a plating treatment that can give a feeling of a metal material.

While the surface of the injection part key is plated as described above, an injection part key having a metal material feel can be obtained, while the plating for surface treatment of the injection part key is copper-nickel-6 chromium plating or nickel-6. Since most of chromium plating is caused, environmental pollution such as groundwater and soil is caused by inducing environmentally harmful substances due to plating, as well as copper-nickel-hexavalent chromium plating or nickel-6 chromium plating. This is subject to the regulation of environmentally hazardous substances, so manufacturing difficulties arise that must not adversely affect the user's body.

In addition, nickel itself causes allergic diseases, as well as peeling nickel applied during use, the user with allergic dermatitis has a problem that should be used with care.

Despite the above-mentioned problems, the reason why the use of the copper-nickel-6-valent chromium plating or the nickel-hexavalent chromium-plated injection part key is to obtain a feeling of the metal material from the injection part key as described above. This is because it is easy to secure the light transmitting part to be able to easily select and use the component key at night.

As a component key for solving the above-mentioned disadvantages of the injection component key, a component key using a metal plate may be exemplified.

A part key using a metal plate is a button of an electronic product of Utility Model Registration No. 296278.

The electronic product button of the prior registration design consists of the metal button part which cut | disconnected the metal plate, and the resin insulation part assembled to a metal button part.

The pre-registered electronic product button is formed of a resin insulating portion made of silicon, urethane, or the like on the bottom of the metal button portion.

In the button made as described above, the resin insulating portion is bonded to the metal button portion by an adhesive or the insert is injected.

The button of the pre-registered design has a metal button part made of metal material, and the surface of the button is made of an injection-molded material to solve the environmentally harmful substances caused by copper-nickel-hexavalent chromium plating or nickel-hexavalent chromium plated injection part keys. It has advantages

However, the above-mentioned preliminary registration has a disadvantage in that the resin insulator is simply injection-molded to the metal button parts which are hardly adhered to each other, so that the metal button part and the resin insulator are easily separated during use, which impairs the reliability of the product. Since the metal button part is formed by simple cutting, it is not only difficult to shape the shape of the metal button part, but also has the disadvantage that a lot of defects occur due to the shape of the metal button, as well as the simple cutting without the surface treatment. Could not feel the texture and the metal button can be made by using the metal material directly to get the feel of the metal material, but the price of the product is increased and the weight of the product is caused, of course, Since it is a simple cutting of the metal plate, it is impossible to light the back, so there is no light A lucky place or at night two minutes of the character number of key components (buttons keys) are inconvenient to use difficult.

The present invention is to solve the shortcomings of the component key formed by the metal material of the conventional component key used in the portable communication device, the purpose is to include a letter, symbol, etc. on the metal plate surface treated to have a feeling of the metal material After forming the part key pattern, and cutting the part key pattern formed on the metal plate with the printing film attached to give the color printing effect on the formed letters, symbols, etc., the part key member is shaped, and then By filling any one of rubber-based or synthetic resins such as silicone or urethane into the space to manufacture the part key including the metal part key member, the metal part key can be manufactured at a low price while giving the impression of the metal material, while at the same time increasing productivity. At the same time, the back lighting can be done as in the injection part key. It is easy to operate the parts key, and since nickel or hexavalent chromium is not used, there is no cause of environmental pollutants, and the back lighting is possible to prevent skin disease (allergy) caused by the use of portable communication devices. A part key of a portable communication device is provided.
