Abstract: A connecting slot of appropriate size is punched for receiving a connector in the upper casing of a motherboard module of the present invention; the connector is soldered to the motherboard by a base; a screw hole is disposed each on both ends of the base; a mounting plate is extended each from both ends of the connecting slot of the metal upper casing into the connecting slot, and the end is bent and attached the upper surface of screw holes on both ends of the base and forms a hole relate to the screw hole; a bolt is passed through the hole and secured into the screw hole, and the mounting plate is tightly pressed and secured to the base to electrically ground the connector with the casing in order to provide the grounding for eliminating electromagnetic interference and fit various connectors and enhance the securing effect.

Abstract: The present invention is an installation slot with an oblique guide plate, whose motherboard is wrapped by a casing, which constructed by an upper metal casing and a lower metal casing. The motherboard is isolated in a closed room of the casing except for plural necessary open holes; thus a height difference is between the motherboard and the casing. Wherein an installation slot is on the casing and internally set a connector. A rim of the installation slot extends from the casing to an internal of the installation slot and downward at least an oblique guide plate, and an edge of the rim is as close as possible to reach an edge of the connector for that a few fingers being capable of clamping a plug from a motherboard module, the installation slot, the connector to a plurality of pins inside the connector, and then the pins electrically connecting to outside via several connection wires for enhancing EMI shielding effect and reducing noise.

Abstract: The present invention is that a digital television comprises an inside, a maintain cover, a panel of a front of the digital television, at least one DVD slot and an ejection button around the panel, a hollow sliding frame inside the digital television, an exit of the sliding frame facing the maintain cover, a personal computer mainframe, which comprises a case, a plurality of grooves on upper surface and lower surface of the case and being installed along a central line of the case, a handle on the case toward an end surface of the maintain cover and being capable of pushing the personal computer mainframe into the sliding frame from the exit of the sliding frame being on the reverse side of the end of the maintain cover, a protruded DVD player connecting to the DVD slot and the ejection button for fast assembling and disassembling the computer mainframe to be in maintain and upgrade and offering multiple functions and options to consumers.

Abstract: The invention is related to a fixture device for motherboard module by placing two fixing plates on the locational surface of a major control device. A ∏-shaped slider with the same width as the motherboard module is formed on the base plate below the fixing plate. Additionally, a locating button in front of the opening of the slider is used to secure the motherboard module into the slider. Through this approach, the motherboard module can be easily installed/disassembled by pressing the locating button without using any tools or test fixtures.

Abstract: The present invention is a chute positioning apparatus. Two suitable places of two contour lines of top and bottom sides of a positioning board have two rows of chutes. Each chute is a strip open. A half of the chute is a loading and unloading section with a big open, an end of the loading and unloading section connects to an oblique guide board inclined toward chute. Another half of chute is a tightening section with a small open. Two adjacent sides of the two chute rows both are lines, which means each chute of one row is the same height as others, another row is the like. Two suitable places of two ends of a lower contour line of the positioning board have their own guide board, each guide board is fixed on positioning board and vertically and externally protrudes to form a flat base. To use the guide board and the oblique guide piece to guide fixing piece coming in and going out from chute for easily loading and unloading a sub-PCB box and promoting the efficiency of assembly and maintenance.

Abstract: The present invention relates to an adjustable height apparatus applied to a horizontal projector and comprises a shield assembly, a supporting means, a compression link and a lever. When adjusting the projection elevation, an external force is applied on an adjusting button of the top wall of the projector. The compression link, connecting with the button, makes a vertical movement according to the external force and pushes the detent of the lever to depart from contact with the axial height-positioning component. The sleeve extends toward the outside of said shell by the elasticity of a first elastic component for adjusting a suitable height of the bottom base of the supporting means of the projector.
