## Abstract

A sliding hard disk drive mounting hardware includes a sliding box inserted in a recessed chamber on a computer mainframe and releasably locked in place through tenon-and-mortise joints to hold a hard disk drive for permitting the i/o port of the hard disk drive to be electrically connected to the master board of the computer mainframe through an interference elimination circuit board and an interface circuit board. A LED indicator is turned on by means of the control of a control card as the hard disk drive is installed to produce a signal of low potential, or turned off as the hard disk drive is not installed.

## Claims

### Claim 1

A sliding hard disk mounting hardware comprising:
a hard disk drive having a plurality of screw holes spaced on a top surface thereof, an input/output port attached with an interference elimination circuit board assembly, said interference elimination circuit having a mainframe connector on the outside;
a sliding box consisted of a flat, rectangular box body covered with a cover to hold said hard disk drive, said box body having a trapezoidal opening on a vertical front wall thereof, a channel behind said trapezoidal opening, a horizontal guide board extended outwards from said vertical front wall, two tenons spaced on said horizontal guide board, two longitudinal grooves on two opposite vertical side walls thereof on the outside, and four screw holes on inside four corners thereof, said cover comprising a first set of countersunk holes respectively connected to the four screw holes on said box body by screws, a second set of countersunk holes respectively connected to the screw holes on said hard disk drive by screws, and a downward plate adjacent to a front end thereof stopped against said interference elimination circuit board above said mainframe connector;
a computer mainframe having a recessed chamber into which said sliding box fits, two side rails inside said recessed chamber on two opposite sides respectively fitted into said two longitudinal grooves on said box body, two spaced mortises into which said two tenons on said box body fit respectively, an interface circuit board having a connector on one side toward said recessed chamber for connecting said mainframe connector of said interference elimination circuit board of said hard disk drive to a master board through a flat cable, a LED indicator on a peripheral wall thereof electrically connected to said master board; and
wherein said LED indicator is turned on by means of the control of a control card as said hard disk drive is installed to produce a signal of low potential, or turned off as said hard disk drive is not installed.
