Description
Technical field:
The present invention relates to a kind of power-supply device, specifically is a kind of DC ATX electric power for vehicle mounted computer of miniaturization.
Background technology:
Direct current ATX power supply is a kind of working power that is widely used in vehicle-mounted computer, its effect be the automobile storage battery voltage transitions of 12V or 24V become inner 3.3V, the 5V that uses of vehicle-mounted computer, 12V or-DC voltage such as 12V.At present, the prior art DC ATX electric power for vehicle mounted computer is generally the square PCB circuit board of a block length, the welding by one side of described PCB circuit board is connected to the corresponding work circuit, except being welded with the corresponding work circuit, also be provided with a 2*10PIN socket (public affairs) that is electrically connected with the relevant work circuit on the described PCB circuit board, described 2*10PIN socket (public affairs) is electrically connected with 2*10PIN socket (public affairs) on the vehicle-mounted computer mainboard by 2*10PIN plug (mother) patchcord, thereby realization is to the power supply of vehicle-mounted computer mainboard.
There is following defective in actual applications in the prior art DC ATX electric power for vehicle mounted computer of said structure: 1, though 2*10PIN plug (mother) patchcord can realize being connected between direct current ATX power supply and the vehicle-mounted computer mainboard, but because the connecting line of 2*10PIN plug (mother) patchcord is many, it is big and need be installed in the vehicle-mounted computer mainframe box in addition to add the volume of PCB circuit board of ATX power supply, therefore, prior art direct current ATX power supply not only in the vehicle-mounted computer mainframe box occupation space bigger, and because its a part of electric energy wants loss in patchcord, so its power supplying efficiency is lower; 2, because prior art direct current ATX power supply occupation space in the vehicle-mounted computer mainframe box is bigger, and the space of placing the vehicle-mounted computer mainframe box in the car is more limited, therefore, prior art direct current ATX power supply is easy to generate a large amount of electromagnetic interference (EMI) and reduces the stability of vehicle-mounted computer system work greatly.
Summary of the invention:
The technical problem to be solved in the present invention is, provides a kind of and not only takes up room for a short time, and power supplying efficiency is low, and electromagnetic interference (EMI) is little, the DC ATX electric power for vehicle mounted computer that system works stability is high.
Technical solution of the present invention is that a kind of DC ATX electric power for vehicle mounted computer with following structure is provided: it comprises the PCB circuit board, is arranged on power input and the connector that can be connected on the socket I that is located on the vehicle-mounted computer mainboard on the PCB circuit board; Described PCB circuit board has two and be parallel to each other; Described two PCB circuit boards that are parallel to each other are connected with connector simultaneously; The pros and cons of described every PCB circuit board is provided with the operating circuit of mutual electrical connection; Described connector is electrically connected with operating circuit.
After adopting above structure, compared with prior art, the present invention has the following advantages: because two PCB circuit boards among the present invention are overlapped, and the pros and cons of every PCB circuit board all is welded with the corresponding work circuit, thereby mechanical dimension of the present invention is reduced greatly, in addition, because two PCB circuit boards of the present invention all are to be connected with connector, and connector can directly plug on the vehicle-mounted computer mainboard, in other words, the present invention does not need to use the various 2*10PIN plug patchcord of circuit just can plug on the vehicle-mounted computer mainboard as memory bar, thereby not only reduced occupation space required for the present invention, and power supplying efficiency of the present invention has been improved greatly because need not to use patchcord; Because occupation space required for the present invention is little, so can prevent in the vehicle-mounted computer mainframe box that the present invention from producing too much electromagnetic interference (EMI), thereby guarantees that the present invention has the higher system job stability.

Embodiment:
The invention will be further described below in conjunction with the drawings and specific embodiments:
As Fig. 1, Fig. 2 and shown in Figure 3, the prior art DC ATX electric power for vehicle mounted computer is generally the square PCB circuit board of a block length, the welding by one side of described PCB circuit board is connected to corresponding work circuit 7, except being welded with corresponding work circuit 7, also be provided with a 2*10PIN socket II8 who is electrically connected with relevant work circuit 7 on the described PCB circuit board, described 2*10PIN socket II8 is electrically connected by the socket I4 of the 2*10PIN on the patchcord of 2*10PIN plug and the vehicle-mounted computer mainboard 3, thereby realization is to the power supply of vehicle-mounted computer mainboard 3.
As Fig. 4, Fig. 5, Fig. 6 and shown in Figure 7, unlike the prior art, DC ATX electric power for vehicle mounted computer of the present invention comprises two sizes are less and be parallel to each other PCB circuit board 1, is arranged on power input 5 on the PCB circuit board 1 and the connector 2 of a 2*10PIN; The connector 2 of described 2*10PIN can be connected on the socket I4 of the 2*10PIN that is located on the vehicle-mounted computer mainboard 3; Described two PCB circuit boards that are parallel to each other 1 are connected with the connector 2 of 2*10PIN simultaneously; The pros and cons of described every PCB circuit board 1 is provided with the operating circuit 7 of mutual electrical connection; The connector 2 of described 2*10PIN is electrically connected with operating circuit 7.Operating circuit 7 among the present invention adopts is operating circuit 7 in the prior art ATX power supply, different is, operating circuit 7 among the present invention is to be separately positioned on the pros and cons of two PCB circuit boards 1, and the size of the PCB circuit board 1 among the present invention is far smaller than PCB circuit board of the prior art, thereby reduced occupation space required for the present invention; In addition, two PCB circuit boards 1 are to be connected with the connector 2 of 2*10PIN after being parallel to each other, it has not only saved the various lead of 2*10PIN plug patchcord, nor need be installed in addition in the vehicle-mounted computer mainframe box (not shown), therefore the present invention not only in the vehicle-mounted computer mainframe box shared space reduce greatly, and power supplying efficiency is improved greatly because need not to use patchcord; In addition, the present invention takes up room reduces not only to make has enough spaces to guarantee heat radiation of the present invention in the vehicle-mounted computer mainframe box, and can prevent the present invention from producing too much electromagnetic interference (EMI) and influence the stability of system of the present invention operation.
