ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to an industrial computer mainframe structure which employs connecting slots of connecting elements to enable mainboards to extend in a horizontal direction instead of being erected in insert slots of the motherboard to thereby reduce the profile of the circuit boards and permit mounting thereof in a computer housing of a height below 2U (1U=4.445 cm).
(b) Description of the Prior Art
With reference to
FIG. 3
, a conventional industrial computer mainframe includes an open housing
100
having a motherboard
200
disposed thereon. The motherboard
200
has a power supply
201
disposed thereon, and is provided with a plurality of insert slots
202
. In use, mainboards
300
having different functions may be inserted into the insert slots
202
uprightly so that the motherboard
200
can be connected to the mainboards
300
via the insert slots
202
. However, since the mainboards
300
are erected in the insert slots
202
, if the height of the mainboards
300
exceed that of the housing
100
, either it is not possible to stack another housing
100
atop the housing
100
or the height of the housing
100
will need to be increased, which will be very space occupying.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide an industrial computer mainframe structure which includes a housing having a motherboard disposed thereon. The motherboard is provided with at least one insert slot. The insert slots receive connecting elements. A horizontal bar is provided with a connecting element. In use, mainboards of the motherboard are inserted into connecting slots of the connecting elements so that they can extend along a horizontal direction. In this way, the profile of the mainboards is lower than the prior art in which the mainboards are directly inserted into the insert slots, and the overall height of the housing can be reduced to allow stacking or more housings.
Another object of the present invention is to provide an industrial computer mainframe structure in which the open end of a housing has at least one horizontal bar mounted thereon. The horizontal bar is parallel to the motherboard and passes through insert slots on the housing. In use, connecting elements inserted in the insert slots may be secured on the horizontal bar to enhance stability thereof.
