Control device used for a computer motherboard on which a plurality of interface cards is inserted
A control device used for a computer motherboard on which a plurality of interface cards is inserted, is composed of an L-shape notch which is opened at a corner or a long strip of notch which is opened at a side edge, of a circuit motherboard positioned in an interior of a computer casing of height of 2U or 1U; a riser card, which is inserted vertically into a preset slot of the circuit motherboard; and an interface short card or an interface long card, which can be fitted into the L-shape notch or the long strip of notch, wherein conduction pins of the interface long, short cards can be inserted into a transversal slot of the riser card, and the interface short card or the interface long card approaches to a same horizontal level as the circuit motherboard, such that the riser card can be added with more slots for insertion of more interface long cards or interface short cards.
1. A control device used for a computer motherboard on which a plurality of interface cards is inserted:
a circuit motherboard which is connected and fixed on a bottom surface of a computer casing, with an L-shape notch being opened at a corner of the circuit motherboard, and a side edge of the L-shape notch being welded with a vertical slot;
a riser card, a side surface at a bottom end of which is welded with a transversal slot, and a bottom end at a side of which is provided with a conduction pin which is inserted into the slot of the circuit motherboard, enabling the riser card to be positioned vertically on the circuit motherboard; and a standardized interface short card, an inner end of which is provided with a conduction pin which is inserted into the transversal slot, and
primary area of which is emplaced into the L-shape notch, such that a surface of the standardized interface short card is substantially on a same horizontal plane as that of the circuit motherboard.
2. The control device used for a computer motherboard on which a plurality of interface cards is inserted, according to claim 1 , wherein a side surface above the transversal slot of the riser card is welded respectively with a plurality of transversal slots, and conduction pins of a plurality of standardized interface long cards are inserted respectively into the plural transversal slots, enabling the plural interface long cards to be overlapped with and parallel to one another, and to be located above the standardized interface short card, as well as to be located in an internal space of the computer casing.
3. The control device used for a computer motherboard on which a plurality of interface cards is inserted, according to claim 1 , wherein the computer casing includes especially the following parts: (a) an I/O board, which is provided with an I/O connection interface, being located at a side of the computer casing to serve as a connection interface of I/O; (b) a frame, which is provided with a ventilation hole, being located in the internal space of the computer casing; and a connection element, which is provided with a vertical board for connecting and fixing the riser card, with a front connection end of which being screwed on the frame, and a rear connection end of which being screwed on the I/O board.
4. The control device used for a computer motherboard on which a plurality of interface cards is inserted, according to claim 1 , wherein the slots of the circuit motherboard are divided into a left and a right set, the conduction pins located at the bottom end at the side of the riser card are divided into a left and a right set, and the two sets of conduction pins are inserted into the two sets of slots.
5. The control device used for a computer motherboard on which a plurality of interface cards is inserted, according to claim 1 , wherein height of the computer casing is standardized height of 2U.
6. A control device used for a computer motherboard on which a plurality of interface cards is inserted, comprising a circuit motherboard, which is connected and fixed on a bottom surface of a computer casing, a side of which is formed with a long strip of continuous notch, with a side edge of the long strip of notch being welded with a vertical slot; a riser card, a side surface at a bottom end of which is welded with a transversal slot, and a bottom end at a side of which is provided with a conduction pin which is inserted into the slot of the circuit motherboard, such that the riser card is positioned vertically on the circuit motherboard; and a full length, full height, standardized interface long card, an inner end of which is provided with a conduction pin, and primary area of which is emplaced into the long strip of notch, such that a surface of the standardized interface long card is substantially on a same horizontal plane as that of the circuit motherboard.
