Abstract: The present invention proposes a resilient sheet of connect port for isolating EM waves, which sheet comprises a main body of rectangular sheet and an outer frame bent toward the same direction from the edge of the main body. The cross section of the outer frame is U-shaped, and a plurality of bumps equally spaced are formed on the outer side surface thereof. A plurality of resilient plates and resilient projective ears slanting forwards are formed on the edge of the outer frame. A raised point is formed on each of the resilient projective ears. The raised points will contact a rear plate set of the case of a computer. The resilient projective ears will be bent backwards due to the push of the rear plate set.

Abstract: A screwless computer case mounting arrangement includes a top-open case body, a top cover covered on the case body, a hollow shell mounted in an opening on the top cover, an axle pivoted to the hollow shell on the inside, a retaining member fastened to the axle in the hollow shell and hooked on a locating frame of said case body to secure the top cover and the case body together, a handle fastened to the axle and adapted for turning by hand to disengage the retaining member from the locating frame of the case body, a spring mounted on the axle and adapted for force the retaining member into engagement with the locating frame of the case body, and a lock installed in the case body and adapted to stop the retaining member from movement relative to the case body.

Abstract: A mobile rack mounting structure includes a mounting frame fixedly mounted in a computer mainframe, and a plurality of CD-ROM player carriers detachably mounted in the mounting frame, the mounting frame having guide plates, supporting plates and retaining holes at two vertical side panels thereof, each CD-ROM player carrier having two sliding rails adapted for moving in and out of sliding tracks defined by the guide plates of the mounting frame, and two handles bilaterally disposed at a front side, the handles each having hooks adapted for engaging the retaining holes at the vertical side panels of the mounting frame.
