    • A printed circuit board assembly and a liquid crystal display (“LCD”) having the same, and more particularly, to a printed circuit board assembly, wherein a board mounted with a heat dissipation plate and a time controller using a spring clip or a hook spring can prevent the board from sagging. An exemplary embodiment includes a heat dissipation plate, a protection plate and a thermal interface material to dissipate heat from a time controller, thereby efficiently dissipating heat from the time controller. Another exemplary embodiment includes a spring clip or a hook spring to increase contact forces among a protection plate, a heat dissipation plate and a board, thereby further improving heat dissipation performance. Exemplary embodiments of the present invention make it possible to provide a printed circuit board assembly, wherein a spring clip supports the bottom of a region of a board in which a time controller is mounted, thereby preventing sagging of the region of the board in which the time controller and a heat dissipation plate are mounted. An LCD having the printed circuit board assembly is also described.
    • 一种印刷电路板组件和具有其的液晶显示器(“LCD”),更具体地涉及一种印刷电路板组件,其中安装有散热板的板和使用弹簧夹或钩的时间控制器 弹簧可以防止板材下垂。 示例性实施例包括散热板,保护板和热界面材料,以从时间控制器散发热量,从而有效地散发来自时间控制器的热量。 另一个示例性实施例包括弹簧夹或钩弹簧,以增加保护板,散热板和板之间的接触力,从而进一步提高散热性能。 本发明的示例性实施例使得可以提供一种印刷电路板组件,其中弹簧夹支撑安装时间控制器的板的区域的底部,从而防止板的区域的下垂,其中 时间控制器和散热板。 还描述了具有印刷电路板组件的LCD。

    • An automatic door opening mechanism for ejecting a video cassette tape of a video cassette recorder (VCR) includes a door mounted at both sides on door brackets in front of a cassette deck opening for inserting/ejecting a cassette tape so as to be opened upwardly and an actuator lever fixed on one end of an actuator shaft rotatably mounted on main frame. The actuator lever has a door locking part formed on one end and a button pressing part formed on the other end. A further door locking part is fixed on the other end of the actuator shaft. A retention arm is fixed on the actuator shaft in the middle thereof. The retention arm has a stopper tiltably mounted on its top. The stopper is vertically positioned under the cassette deck opening so as to be engaged with front and rear lower edges of the cassette tape and to be tilted inwardly by being engaged with the rear lower edge of the cassette tape when inserting the same through the opening. The stopper is returned to its vertical position after complete insertion of the cassette tape.
    • 用于喷射盒式磁带录像机(VCR)的盒式录像带的自动开门机构包括一个门,其安装在用于插入/弹出盒式磁带的盒式磁盘开口前面的门托架的两侧,以向上敞开, 固定在可旋转地安装在主框架上的致动器轴的一端上的致动器杆。 致动器杠杆具有形成在一端的门锁定部和形成在另一端的按钮按压部。 另一个门锁部分固定在致动器轴的另一端。 保持臂在其中间固定在致动器轴上。 保持臂具有可倾斜地安装在其顶部上的挡块。 止动器垂直定位在盒式甲板开口下方,以便与盒式磁带的前后下边缘接合,并且当通过开口插入时通过与盒式磁带的后下边缘接合而向内倾斜。 完全插入盒式磁带后,止动器返回到其垂直位置。
