Description

Computer comprising power supply which locates outside of mainframe

The present invention relates to a computer, and more particularly to a computer having a power supply outside the main body.

Recently, with the development of related technologies, the price for the performance of the computer is gradually lowered, and the computer-based Internet has become the main means of information exchange, and the computer is now widely used as a necessity of life.

FIG. 1 is a schematic view of a main body of a desktop computer commonly used in a home or an office. The main body 11 includes a CD ROM drive 12, a floppy disk drive 13, and a hard disk drive 14. And a main board 15 for connecting a CPU and controlling the operation of the entire computer, and a plurality of insertion slots (not shown) for inserting a VGA card and a LAN card. .

The main board 15 in the figure shows a standing state, but may be arranged differently.

In addition, a built-in power supply (16) for supplying power to such modules and various components, the power supply 16 is a DC 5V, 6V 220V AC power flowing through the AC power cable (17) It converts and supplies driving power required for each component such as 12V.

However, the conventional configuration in which the power supply unit 16 is installed inside the main body 11 has some problems. The first is that it acts as an obstacle to the slimming of the product, which has recently been emphasized. Although the fan is attached, heat generated in the process of converting AC power to DC power increases the internal temperature of the main body 11, which adversely affects peripheral components or modules.

Third, since various electronic components sensitive to electric shock are concentrated inside the main body 11, even in the current structure in which AC power is drawn into the main body 11, even if a small problem occurs in electrical stability, It is likely to have a fatal effect.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and aims to provide a computer that can reduce the size of the computer, minimize heat generation inside the body, and prevent damage to components or modules due to electric shock. .

In order to achieve the above object, the present invention includes a main body having a plurality of modules; A power supply unit located outside the main body and converting AC power into DC power; Provided is a computer including a power cable connecting the power supply and at least one of the modules.

At this time, the power cable, one end is coupled to the first connector having a plurality of connection terminals, the other end is an internal cable connected to at least one of the module; One end has a second connector coupled to the first connector, the other end may include an external cable connected to the power supply, a bracket having an insertion hole is coupled to the computer body, the first connector is connected The terminal may be fixed to the insertion hole to be seen from the outside.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

2 illustrates a configuration of a computer according to an exemplary embodiment of the present invention. For convenience, peripheral devices such as a monitor, a mouse, and a keyboard are not shown.

Inside the main body 110, a CD ROM drive 120, a floppy disk drive 130, a hard disk drive 140 and a main board 150 connected to them and mounting a CPU to control the operation of the entire computer. The fact that it is built-in and that the insertion slot (not shown) for inserting a VGA card, a LAN card, etc. in addition to these are included is the same as the conventional.

The biggest feature of the present invention, it can be said that the power supply 160 is located outside the computer main body 110 as shown.

The power supply unit 160 converts the AC power introduced through the AC power cable 170 connected to one side into DC power and supplies the power to the respective modules or components inside the main body 110. Since the configuration is common, the description is omitted.

In order to supply power, a power cable for connecting the power supply unit 160 and each module is required. In this case, a power cable for directly connecting the power supply unit 160 and each module may be used. As shown in the drawing, it is preferable to separate the internal cable 180 located inside the main body 110 and the external cable 190 located outside.

The inner cable 180 is composed of several strands of cables, one end of which is connected to the first connector 182, the other end of which is connected to the motherboard 150, some of which is connected to the CD-ROM drive 120, and some of which is Some of the floppy disk drives 130 are connected to the hard disk drive 140 and the like.

The other end of the internal cable 180 connected to the motherboard 150 or each drive 120, 130, 140 is normally connected to the connector, so that it is electrically connected by plugging it into a connection socket formed on the motherboard or each drive. .

The first connector 182 is preferably fixed to the wall surface of the main body for easy connection with the external cable 190, which will be described later, the connection terminal of the first connector 182 should be seen from the outside of course. .

Meanwhile, one end of the external cable 190 is connected with a second connector 192 having a connection terminal for coupling with the first connector 182 of the internal cable 180, and the other end is connected to the power supply unit 160. .

3 is a view illustrating a state in which the external power supply unit 160 and the main body 110 are connected through an external cable 190 according to an embodiment of the present invention, wherein the second connector 192 of the external cable has a main body ( 110) It is connected to the first connector fixed to the back.

The first connector 182 of the inner cable 180 and the second connector 192 of the outer cable 190 are shown in Figure 4, the connector of each connector 182, 192 is female means Should be in the form corresponding to each other, in the drawings are shown by omitting the wall surface of the main body 110 for convenience.

3 again, the power supply unit 160 has a ventilation hole 161 for natural ventilation on the side, and is provided with a power switch and an outlet connected to an AC power cable. Although not shown, a cooling fan may be coupled to the inside.

Reference numeral 112 is a bracket installed to fix the first connector to the back of the main body 110. As shown in FIG. 5, since the insertion hole 113 is disposed in the center, the first connector 182 is fixed thereto. In this case, the connection terminal of the first connector 182 should be seen from the outside as described above.

Since the bracket 112 may fix the first connector 182, its shape may be variously modified by those skilled in the art.

Looking at the process of supplying power from the computer having the above configuration with reference to Figures 2 and 3, first, after the AC power supplied through the AC power cable 170 is converted into a DC power from the power supply unit 160 After passing through the external cable 190 to one end of the internal cable 180 inside the main body 110, the other end of the internal cable 180 goes through the process of supplying the necessary power to the motherboard and various drives. .

In the above description of the preferred embodiment of the present invention, but the present invention is not limited to this and can be variously modified or modified by those skilled in the art, this modification or modified technology described in the claims to be described later As long as it includes the technical idea of the present invention, it will be obvious that it belongs to the scope of the present invention.

According to the present invention, the design space is increased due to the enlarged space, thereby making it possible to easily slim the computer and to accommodate more types of cards by using the expanded space without reducing the size.

In addition, it is possible to minimize the heat generation inside the main body to prevent deterioration of the built-in various electronic components, it is possible to increase the electrical stability because the AC power is not drawn into the interior.
