Technical field
The present invention is the power system about PC haply.Especially about design with make the method for the power system with modularization and integrated cable interface in order to standard output (O/P) cut cable of being connected the printed circuit board (PCB) (printed circuit board (PCB)) of a plurality of outputs (O/P) cable group to some power systems, this power system provides from the power supply of outside with the DC power supply of supply predetermined voltage level each subsystem to PC via these O/P cable group.
Background technology
The power system of PC need provide power supply to the cumulative peripherals of number, as modem or tool machine, CD player, scanner, Winchester disk drive, floppy drive or the like.Because the development trend of PC can expect that this trend will continue at present always.Especially from strength to strength and can handle under the situation of multimedia and multiplex's function in the function of microprocessor (being commonly referred to as CPU (central processing unit), i.e. CPU).Except this trend, the PC of each kind and kenel needs unique arrangement and structure so that place these peripheral units in different positions more.For the extremely complicated demand of power supply to all peripheral units that provide is provided, need to comprise the power system of feed cable and interface connector so that meet the specification of each kenel personal computer system design separately according to the requirement design at each family.
The known power system 10 of figure one expression, it comprises several outputs (O/P) cable group, i.e. cable group 15-1,15-2,15-3 and 15-4 are in order to connect CPU and different peripherals such as Winchester disk drive (HDD), floppy drive (FDD), CD player (CDD), data-fax card and fluorescent screen.Power system also has a feed cable 20 in order to be connected to external power source joint 25.The back panel (back-panel) that the external power source joint is arranged at PC usually goes up so that be connected to external power source via the power lead (not shown).Be provided with according to the inner space, the power supply unit in the personal computer system can be placed on different position in the personal computer system.Feed cable 20 and O/P cable group 15-1,15-2,15-3, the length of 15-4 has nothing in common with each other.Therefore, the manufacturing of the power supply unit used of actual PC be design according to the user customize (tailor-make) those cables then and according to each buyer's order with its combination.
Must pay special attention in welding or when welding the certain connection points of each indivedual O/P cable to the printed circuit board (PCB) of power supply unit.Because this independently cable connection structure, known manufacturing process must be being the length of each O/P cable of based process individually, because may have different length when specific O/P cable is designed to be welded to point specific on the printed circuit board (PCB) in advance and is contained in specific cable group each O/P cable so that specific dc voltage to be provided to specific peripheral subsystem.Because this point-to-point design concept, comprise that point on the printed circuit board (PCB) in the power system for example connects and the power system of each O/P cable length design manufactures and designs according to the specification of each brand of client or kenel.
It is the power supply unit that ASTEC AS145-3420 type is used for IBM people's electricity clothes that this power system has an example, and its output cable connects and output cable group such as Fig. 2 A, shown in the 2B.Fig. 2 A is the side view of power supply unit, and wherein a plurality of output cables from the AS145-3420 power supply unit are directly to be connected along A-A ' direction surface from the contiguous panel of power supply unit top.The output cable contact 40 of AS145-3420 power supply unit is with identical shown in the figure one.Fig. 2 B represents the thin portion combination of output cable (being cable group 45-1 to 45-6).Since these output cables 45-1 to 45-6 may be different because of different computer kenel possibilities, the AS145-3420 power supply unit is expressed typical conventional design and is used.It should be noted that in Fig. 2 B each O/P cable is in order to providing specific DC output voltage to specific pin, as each pin that is labeled.The employed dc voltage of these pins can be a ground voltage ,-5 volts, and+5 volts ,-12 volts and+12 volts, as shown.Each O/P cable has different colors to be assigned to the different dc voltages of different O/P cables with easy identification.Because ASTEC be topmost in the world PC IBM has lasting market and occupies power with one of power supply unit manufacturer, shown ASTEC145-3420 has showed the level of the personage in the power supply unit design in the suitable PC specific area.
Therefore, in the field of power supply unit design and manufacturing, still need new system architecture and method for designing so that solve these difficulties and restriction.Especially, the demand that different clients must be provided when the many subsystems that provide power supply to PC for this new system architecture and method for designing, these subsystems may be listed other design thinking of consideration in and different designs is arranged according to packing layout, integrated horizontal, performance level, the function of wanting and multiple computer design person.

Above-mentioned design and manufacturing process provide many advantages.At first, design and manufacturing cost have been reduced by the basic device standardization that makes power system.Do not need just can reach cost-effective purpose to the major part redesign of power system.Secondly, by making the flow process standardization of manufacturing, can finish regularly better and more stable quality control with less variation between tested person and the in check different product line.The 3rd, by all flow processs are cut apart two key steps, i.e. the cable of basic standard basic device and client decision can provide the design of power supply device and make preferable elasticity so that the demand of customer in response is done preferable response.This is because the design of cable and manufacturing are general than being easier to and can making in the short period of time.Infraction in the technological process that in known flow process, in the demand of the power supply unit that determines for the client compatible, often meets with different types of computer framework, thereby can solve by the present invention.
The present invention discloses a kind of novelty and non-obvious system architecture and method for designing so that provide modularization that the PC power system uses and integrated cable interface.Modularization that disclose in this place and integrated cable interface may be comparatively obvious in the design of other electronic product and manufacturing field, yet belong to novel and non-obviously in the power system field that PC is used, and it be the reasons are as follows.
At first, modularization and integrated cable interface are mainly to consider as running is flexible in the design in many electronic product fields with in making, promptly in many subsystems and the design in the operational devices, the simplicity that connects and disassemble, by general use.This interface structure is to establish for downstream user's (end user) interests.On the contrary, be applied in the processing procedure so that reach in design and the elasticity in making as disclosed modularization and integrated interface structure.Specific group between other electronic product with the integrated and modular cable interface of the present invention is diverse and therefore has different purposes and demand.For a specific group such as downstream user may be known and obvious, but this technology is then really not so for another different groups such as power system deviser, because trend of using and potential interests are different fully.
The second, along with the expansion of CPU and storage device capacity can be supported the multi-purpose peripheral units of carrying out more, the trend that the oriented more complicated system of computer industry moves.The design of power system need be caught up with final development.Computermaker, i.e. the buyer of power supply unit, and downstream user orders about power system and satisfies more different types of system architectures.The demand of this trend and design is with integrated and standardization is opposite.Therefore in implementing, when ripe already modularization and integrated cable interface, in the power system design field, produce a blind spot as many electronic products field.
