  • Patent number: 7704096
    Abstract: A coaxial cable connector including an insulating housing, a terminal and a conductive shell is provided. The insulating housing has an insulating arm disposed thereon. The terminal is disposed in the insulating housing. A portion of the terminal is bent towards the insulating arm to form a tongue portion and an opening thereon. The conductive shell includes a body and a bending portion. The body holds the insulating housing. The bending portion and the tongue portion are located on a side and a reverse side of the insulating arm respectively. The bending portion is capable of pressing the tongue portion by the insulating arm to press the tongue portion toward the opening and to connect the tongue portion to an internal conductor of a coaxial cable so as to press the internal conductor into the opening.

  • Publication number: 20070275751
    Abstract: The present invention provides a faceplate having keys. The keys are defined between protrusions under a film. By pressing down a key, a contact is pushed to be in touch with a circuit board to control the circuit board. Consequently, the faceplate is easily assembled and has a reduced production cost.

  • Patent number: 7232969
    Abstract: A keypad suitable for being disposed on a circuit board is provided. The keypad is in contact with the circuit board to generate an electrical signal. The keypad includes a flexible light guide plate, a key pattern, a passivation layer, a light source, and a reflector. Wherein, the key pattern and the passivation layer are both disposed on a first surface of the flexible light guide plate, and the passivation layer covers the key pattern. In addition, the light source and the reflector are both disposed at one side of the flexible light guide plate, and the reflector covers the light source. The keypad has better display brightness such that the user can easily recognize the patterns of the keys.

  • Publication number: 20060273494
    Abstract: An injection molding process for fabricating an in-mold decoration is provided. The process includes the following steps. First, a plastic substrate is provided. Then, an ink pattern is formed on the plastic substrate. A pre-forming process is carried out on the plastic substrate. A trimming process is performed to cut the plastic substrate into a plurality of fashioned units. A resin injection process is performed to coat a plastic layer over the ink pattern on each fashioned unit. A hardening layer is formed over each fashioned unit to cover the surface of each fashioned unit, which is far away from the ink pattern.

  • Publication number: 20060255492
    Abstract: An In-Mold Decoration process has the following steps. A plastic film is provided. A hardening layer is formed under the plastic film. A metal film is formed under the hardening layer. A colored ink layer is coated under the metal film and is then baked. An appliqué, after being colored-ink coated, is preformed into a desired shape by heat and pressure. The preformed appliqué is then precisely trimmed. The appliqué is inserted into the mold cavity and a compatible material is injection molded behind the appliqué. A finished IMD product with metallic appearance is presented.

  • Publication number: 20060214322
    Abstract: An in-mold decoration fabrication of injection molding is provided as follows. First, a plastic substrate is provided and a mask is disposed on the plastic substrate. A patterned metal film is formed on a surface of the plastic substrate without covering the mask. After the mask is removed, an ink pattern is formed selectively on the patterned metal film. Then, a plurality of forming units on the plastic substrate are preformed and separated to each other by trimming the plastic substrate. Finally, a step of resin injection is provided to cover the patterned metal film, ink pattern of each of the forming units and the exposed surface thereof.
