Description

Voltage conversion device

The present invention relates to a voltage conversion device, and more particularly to a voltage conversion device for connecting a motherboard to a power supply.

Generally, most motherboards used by servers or computers require various driving voltages such as 3.3V, 5V, and 12V to maintain normal operation of the computer. When a single-output power supply is used to drive the aforementioned server or computer. In the case of a motherboard, it is often necessary to pass a complicated voltage conversion device to achieve a multiple output. At present, a common method is to add a voltage conversion device between the power supply and the motherboard, and the power supply and the motherboard must be separately connected by the cable to achieve the purpose of converting the voltage. However, this method not only causes system assembly. It is not easy, and it will greatly increase the manufacturing cost. In addition, the use of the cable connection method is also prone to energy or power loss, thereby reducing the efficiency of the power supply.

An embodiment of the present invention provides a voltage conversion device including a body, a first connector, and a second connector. The first connector is disposed on the body and electrically connected to a power supply. The second connector is disposed on the body, wherein the second connector is detachably fixed to a motherboard and electrically connected to the motherboard.

In an embodiment, the first and second connectors are ATX connectors.

In one embodiment, the aforementioned power supply provides a DC voltage of 12V to the power conversion device.

In an embodiment, the output voltage values of the power conversion device include 12V, 3.3V, and 5V.

In an embodiment, the first and second connectors are respectively disposed on opposite sides of the body.

In one embodiment, the voltage conversion device further includes a third connector disposed on the body for electrically connecting to a hardware device.

In an embodiment, the voltage conversion device further includes a positioning post, wherein the positioning post is detachably fixed to the motherboard.

In one embodiment, the first connector protrudes from one side of the body, and the side edges are perpendicular to the extending direction of the second connecting portion.

The above described objects, features, and advantages of the invention will be apparent from the description and appended claims

First, referring to FIG. 1 , a voltage conversion device 100 according to an embodiment of the present invention is electrically connected to a power supply 200 and a motherboard 300 of a computer or a server. As shown in FIG. 1 , the power supply 200 can output a DC voltage of 12V, wherein the transmissive voltage conversion device 100 can convert the 12V DC voltage generated by the power supply 200 into different driving voltage outputs, for example, 12V respectively. 3.3V, 5V and 5VSB (standby voltage), in order to provide a stable driving voltage of the motherboard 300 to maintain the normal operation of the computer or the server.

The voltage conversion device 100 in this embodiment mainly includes a body 10, a first connector 11, and a first embodiment. The second connector 12 and the third connector 13 may include a printed circuit board. The first connector 11 is disposed on the body 10 and protrudes from one side 101 of the body 10 for electricity. The foregoing power supply 200 is connected to the power supply 200, wherein the front side 101 is substantially perpendicular to the extending direction of the second connecting portion 12; further, the second connector 12 is protruded from the bottom surface 102 of the body 10 for electrical connection. Motherboard 300.

Referring to FIG. 3 again, it can be clearly seen from FIG. 3 that the first connector 11 is fixed to the top surface 103 of the body 10, and the second connector 12 is fixed to the bottom surface 102 of the body 10; in other words The first and second connectors 11 and 12 are respectively located on opposite sides of the body 10. The first connector 11 can be connected to the power supply 200 through a wire during installation, and the second connector 12 can be directly connected to the motherboard 300. The combination of the corresponding connectors (for example, ATX connectors) allows the voltage conversion device 100 to be fixed to the motherboard 300, whereby the voltage conversion device 100 can be used for voltage conversion. On the other hand, the voltage conversion device 100 can be firmly coupled to the motherboard 300 by the positioning post S protruding from the bottom surface 102 of the body 10 during installation to prevent the voltage conversion device 100 from being released from the motherboard 300.

It should be particularly noted that a DC/DC voltage conversion circuit is provided on the body 10 of the voltage conversion device 100, thereby converting the 12V DC voltage provided by the power supply 200 into 12V, 3.3V, and 5V required by the motherboard 300. And the 5VSB (standby voltage); the voltage conversion device 100 in the embodiment directly inserts the second connector 12 on the bottom surface 102 of the body 10 directly with the corresponding connector on the motherboard 300 by pluggable In combination, there is no need to connect through the wires between the voltage conversion device 100 and the motherboard 300, thereby achieving space saving and power loss avoidance. For example, the first, second, and third connectors 11, 12, and 13 can be used. A connector of the ATX (Advanced Technology eXpanding) interface specification, wherein the third connector 13 is selectively disposed on the body 10 as needed to connect other hardware devices or boards.

In summary, the present invention provides a voltage conversion device, which mainly includes a body, a first connector, and a second connector. When used, the power supply can be connected to the first voltage conversion device through a wire. The connector, while directly inserting the second connector on the motherboard, can convert the 12V DC voltage generated by the power supply into a plurality of different driving voltages required by the motherboard. Since the present invention does not need to be connected through a wire between the voltage conversion device and the motherboard, the power and energy loss can be effectively reduced, and space and cost can be effectively saved, and the user can be assembled.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the invention. Those skilled in the art having the ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
