Embodiment
For convenience of description, the golden finger that below will continue to use three types of PCI, PCI-E and PCI-X comes for example, and so this only illustrates, and is not in order to limit the present invention.
Fig. 5 is the synoptic diagram according to the load measuring tool of the utility model one embodiment.Please refer to Fig. 5, wherein indicate 502 and be expressed as a main body, realize with printed circuit board (PCB) in this example, is four thumb-acting switch and indicate 504～510, and indicating 512～518 is four loads.In addition, indicate 520 and be expressed as PCI-E formula golden finger, be expressed as PCI formula golden finger, be expressed as PCI-X formula golden finger as for indicating 524 and indicate 522.Above-mentioned PCI-E formula golden finger 520, PCI formula golden finger 522 and PCI-X formula golden finger 524 are arranged at three different sides of main body 502 respectively.
Above-mentioned load measuring tool can be explained its operation with Fig. 6, Fig. 6 be load measuring tool shown in Figure 5 equivalent electrical circuit illustrate figure.Please refer to Fig. 6, wherein indicate 504～524 correspondences that are respectively among Fig. 5 and indicate the object of being censured.In this figure, three golden fingers that are arranged on different sides are put together on one side, conveniently to illustrate and to inspect.In addition, indicate 520-1 and 520-2 and be respectively in the PCI-E formula golden finger 520, in order to couple two power pins of power supply V1 and V2; Indicating 520-3 then is in the PCI-E formula golden finger 520, in order to couple the common electric potential pin of common electric potential GND.Indicate 522-1 and 522-2 and be respectively in the PCI formula golden finger 522, in order to couple two power pins of power supply V1 and V2; Indicating 522-3 then is in the PCI formula golden finger 522, in order to couple the common electric potential pin of common electric potential GND.Indicate 524-1 and 524-2 and be respectively in the PCI-X formula golden finger 524, in order to couple two power pins of power supply V1 and V2; Indicating 524-3 then is in the PCI-X formula golden finger 524, in order to couple the common electric potential pin of common electric potential GND.In this example, above-mentioned power supply V1 for example is a 12V voltage, and power supply V2 for example is a 3.3V voltage.
In Fig. 6, pin 520-1,522-1 and 524-1 three couple mutually, and pin 520-2,522-2 and 524-2 three couple mutually, and pin 520-3,522-3 and 524-3 three couple mutually.That is to say, in three golden fingers of Fig. 6, electrically connect mutually in order to the pin that couples power supply V1 equally, electrically connect mutually in order to the pin that couples power supply V2 equally, and electrically connect mutually in order to the pin that couples common electric potential GND equally.Thus, when the user is plugged in PCI-E formula golden finger 520 when testing in the PCI-E slot (not illustrating), computer system just can see through the PCI-E slot power supply V1, power supply V2 and common electric potential GND are coupled to pin 520-1,520-2 and 520-3 respectively, so the user just can be by switching the size that those switches change load.
In like manner, when the user is plugged in PCI formula golden finger 522 when testing in the PCI slot (not illustrating), computer system just can see through the PCI slot power supply V1, power supply V2 and common electric potential GND are coupled to pin 522-1,522-2 and 522-3 respectively, so the user also can be by switching the size that those switches change load.And PCI-X formula golden finger 524 is plugged in when testing in the PCI-X slot (not illustrating) as the user, computer system just can see through the PCI-X slot power supply V1, power supply V2 and common electric potential GND are coupled to pin 524-1,524-2 and 524-3 respectively, so the user equally can be by switching the size that those switches change load.
In above-mentioned example, the number of the arrangement position of the shape of all types of PCI golden fingers, pin sum, pin, power pin and common electric potential pin is all just in order to give an example, for convenience of description, so this does not influence the user and integrates dissimilar PCI golden fingers according to the spirit of the foregoing description.Certainly, the also also non-limiting common electric potential pin that can only see through in each PCI golden finger of each load couples common electric potential GND.In addition, the above-mentioned switch and the number of load also can be done increase and decrease according to user's actual needs, there is no certain qualification.For instance, if the user does not need to use power supply V2 when testing, so just switch 504 and 506, load 512 and 514 can be removed.If the user wants when power supply V1 one supplies so far the load measuring tool again, this load measuring tool just can provide load 516 at once, so just switch 508 can be removed, and load 516 is directly connected in all types of PCI golden fingers, in order to couple the pin of power supply V1.If the user wants to increase the load of power supply V1 again, just the load that the institute desire increases can be connected in load 516 or 518 with parallel way, and can increase switch again and determine whether newly-increased load coupled is arrived power supply V1.
In addition, have the knack of this skill person and should be known in that aforementioned body also can be other forms of supporting body, and above-mentioned three kinds of dissimilar PCI golden fingers also can be done suitable configuration according to the external form of supporting body, as long as can be plugged in corresponding PCI slot.And if develop the PCI golden finger that other types, equally also can do integration according to the mode of the foregoing description institute teaching.
By the teaching of the foregoing description, can put out the most basic a kind of load measuring tool of the present invention in order, it includes main body, first kind PCI golden finger, the second type PCI golden finger, the 3rd type PCI golden finger and first load.First kind PCI golden finger, the second type PCI golden finger and the 3rd type PCI golden finger all are arranged on the main body, and have first power pin, second source pin and the 3rd power pin respectively, and above-mentioned power pin is all in order to couple first power supply.First load also is arranged on the main body, and couples first power pin, second source pin and the 3rd power pin.
In sum, the utility model is because of being incorporated into three kinds of dissimilar PCI golden fingers on the same main body, and will interconnect in order to the pin that couples same voltage swing in these three kinds of PCI golden fingers, therefore no matter which kind of PCI golden finger to remove to plug the PCI slot of corresponding types with, all can use same load, so can reach the purpose of integrating three kinds of dissimilar PCI golden fingers.Also because so, such load measuring tool not only makes things convenient for the tester to test, and also is more conducive to deposit.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; anyly have the knack of this skill person; in not breaking away from spirit and scope of the present utility model; when doing a little change and retouching, therefore protection domain of the present utility model is worked as with being as the criterion that claim was defined.
