Abstract

A computer double-power-supply switching card comprises a computer expansion slot fixing plate, a circuit board, two computer power supply 20PIN sockets, and a computer power supply 20PIN plug with a cable of certain length. The switching card is fixed in the computer expansion slot fixing plate through screws, and two computer power supply 20PIN plugs are both connected to the switching card. The computer power supply 20PIN plugs on the switching card are connected to a mainboard of a computer. Two computer power supplies connected on the switching card can be simultaneously turned on/off, when the power button on the computer is touched. One of the power supply connected on the switching card mainly feeds the mainboard, and the other power supply feeds the hard disk, the CD-ROM drive and other peripheral devices of a computer. In the utility model, two miniwatt computer power supplies are used to replace a high power computer power supply, which reduces costs.

Description

A kind of computing machine dual power supply adapter

Technical field

The utility model relates to a kind of computer power supply connecting device, a kind of specifically computing machine dual power supply adapter.

Background technology

The equipment that is connect on the computing machine is more and more at present, as a plurality of hard disks, a plurality of CD-ROM drive, high-performance video card, multi-core CPU, printer, scanner, charger for mobile phone even electric heating plate mat etc., the continuous interpolation of computer fittings has proposed requirements at the higher level with upgrading to power supply, and the output power of a power supply is always limited, the power of computer power supply of normal configuration is all between 200W-300W, for the power consumption that rolls up, often there is computing machine that faults such as deadlock take place because of the unable supply of power supply.Buying a powerful computer power supply is a kind of effective solution really, but expense is higher, the power supply of changing has simultaneously just become electronic waste, again the chance of Li Yonging seldom, we often can see that also unit, family eliminate the computing machine that gets off and become electronic waste.Even the power of large power supply enough satisfies the power requirement of existing hardware equipment, but 4Pin " D " the type plug that power supply provides also is limited, if the peripheral hardware all too many also can be not enough.

Summary of the invention

The purpose of this utility model is at above deficiency, and a kind of computing machine dual power supply adapter is provided, and makes full use of existing power supply, provide two small-power powers to replace the solution of a large power supply, improve stability, the reliability of power supply, reduce upgrade cost simultaneously, reduce electronic waste.

The technical matters that solves:

Solved the problem that too much causes power supply instability at present because of the computing machine connected equipment, a kind of computing machine dual power supply adapter is provided, dual power supply is worked simultaneously and respectively to the distinct device power supply, has been improved stability, the reliability of power supply.

Technical scheme:

The 20Pin plug of two computer power supply bundles of outputs is received adapter simultaneously, the PWR_ON of two 20Pin sockets on the adapter (switching on and shutting down signal), GND (power supply ground) port connect mutually by circuit, one of them 20Pin socket back side on the adapter is connected wire harness receive on the computer motherboard, after computing machine power button touches, can start simultaneously or close two computer power supplies receiving on the adapter by the 20Pin plug.Receive the main main board power supply of giving of two power supplys on the adapter, another mainly gives peripheral hardware power supplies such as hard disk, CD-ROM drive.Computer power supply is placed on the position in the regular picture source that cabinet provides, and another power supply is put in hard disk support bracket below or other correct position.

Beneficial effect:

The utility model is owing to allowing two computer power supplies work simultaneously and separately to the distinct device power supply, having improved stability, the reliability of power supply, adapter novel structure, compact and reasonable, not yielding and damage, easy for installation, simple in structure, debugging is convenient, cheap, wide accommodation.The utility model can also allow old computer power supply bring extra power into play, and reduces the generation of electronic waste.

Among the figure: 1, fixed dam, 2, circuit board, 3, wire harness, 4,20Pin plug, 5,20Pin socket (power 2), 6,20Pin socket (power 1), 7, tie, 8, tie, 9, fixed screw, 10, power is than large power supply, and 11, the less power supply of power, 12, mainboard, 13, power is than the large power supply bundle of outputs, 14, the less power supply bundle of outputs of power, 15, cabinet, 16, power lead.

Embodiment:

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Shown in accompanying drawing 1, accompanying drawing 2, be placed with 20Pin socket (power 2) (5) and 20Pin socket (power 1) (6) in circuit board (2) front, 20Pin socket (power 2) (5) has connect a 20Pin plug (4) at back of circuit board by wire harness (3).Connect with tie (8) between PWR_ON (switching on and shutting down signal) port of 20Pin socket (power 2) (5) and 20Pin socket (power 1) (6); Connect with tie (7) between GND (power supply ground) port of 20Pin socket (power 2) (5) and 20Pin socket (power 1) (6).Circuit board (2) is fixed on the fixed dam (1) by fixed screw (9).

As shown in Figure 3, fixed dam (1) is by the expansion slot baffle plate of screw retention in computer cabinet (15), two computer power supplies (10), (11) all are installed in the computer cabinet (15), and the computer power supply that power is bigger (10) is put in the position that power supply is installed in the cabinet (15); Lower-powered power supply (11) is put under the hard disk rack, on cabinet (15) base plate, with glue or screw fixings.The power supply output line bundle (13) of the computer power supply that power is bigger (10) is connected on the 20Pin socket (power 2) (5) on the circuit board (2); The power supply output line bundle (14) of lower-powered computer power supply (10) is connected on the 20Pin socket (power 1) (6) on the circuit board (2).Circuit board (2) back side wire harness (3) is connected on the mainboard (12) by a 20Pin plug (4).The power lead (16) of lower-powered computer power supply (11) directly inserts from the outside by an expansion slot baffle plate of the bottommost of dismantling.

The computer power supply that power is bigger (10) is mainly used in main board power supply, and lower-powered computer power supply (11) is used for power devices such as hard disk, CD-ROM drive.Because two PWR_ON (switching on and shutting down signal) port, two GND (power supply ground) port connect with tie, after computing machine power button touches, two power supplys receiving on the adapter can start or shutdown signal to receiving simultaneously, two computer power supplies can be carried out startup or closing motion according to oneself state.
