Inner rack of a mobile rack in a computer

#1. Field of the Invention

#The present invention relates to a an inner rack of a mobile rack in a computer, and particularly to an inner rack, which has a signal conversion circuit board to convert the USB interface signal received by the inner signal connector at the outer side thereof into the IDE interface signal via the control IC thereon with an IDE interface connector connecting with an IDE interface storage device therein for the storage device providing functions of hot-swap and plug and play.

#2. Description of Related Art

#The present invention can be more fully understood by reference to the following description and accompanying drawings, in which:

#FIG. 1 is a perspective exploded view of a mobile rack according to the present invention;

#FIG. 2 is an assembled perspective view of the mobile rack shown in FIG. 1;

#Referring to FIGS. 1 and 2, a computer mobile rack basically comprises an outer rack 1 and an inner rack 2 and the inner rack 2 can be slid into the outer rack 2 for connection or slid out for disengagement.

#Wherein, the outer rack 1 has an IDE interface and a USB interface and it has been disclosed in the U.S. patent application Ser. No. 09/983,374. The outer rack 1 is mounted in a space of 5.25 inch of the main unit of the computer and a central room 11 thereof has an automatically returning gate 12. The rear side thereof has an outer circuit board 13 and a conventional 40-pin connector of standard IDE interface and a pair of conventional power input outlets (not shown).

#The present invention is different from the prior art in that the outer circuit board 13 at the external side thereof provides a USB signal connector (not shown due to projection orientation) such that each signal can be parallel connected to an outer side signal connector 131 at the inner side of the outer circuit board 13. The outer side connector 131 has 50 pins and the 5th and the 13th pins are connected to +data and −data signals of the USB signal connector, the 4th and the 29th pins are parallel connected to the power source outlet and the USB connector respectively. The 2nd, the 3rd, the 27th, the 28th pins are parallel connected to the power source outlet and the grounding lines of the USB signal connector. The 1st and 26th pins are parallel connected to +12V power of the USB signal connector. The rest 40 pins are connected to the standard IDE interface connector. Besides, the outer circuit board connects with a switch 14 via a power line 141 on the outer rack 1 so as to control the power source being in a state of ON or OFF.
