Description

Controlled adapter

Technical field

The utility model relates to a kind of adapter, relates in particular to a kind of controlled adapter that is applied to test memory module on the computer motherboard.

Background technology

The application testing of internal memory module generally all carries out on computer motherboard, prior art is come regulation voltage by fixed resistance is replaced with slide rheostat, because resistance fixing on the mainboard is small-sized, being difficult to manual welding replaces, being easy to damage mainboard and test is at stable power circuit conditioning voltage, voltage-regulation scope after the change is smaller, and unstable; When lacking the motherboard power supply circuit theory diagrams, can not determine the power supply backfeed loop of internal memory module, thereby can not do the performance test of determining operating voltage range the internal memory module.Though now on the market by a kind of adapter, be mainly used in the mainboard level test of internal memory module, it mainly acts on is the plug number of times that reduces mainboard internal memory draw-in groove, prolongs the testing host life-span, it does not possess the voltage-regulation function.

The utility model content

In order to solve existing problem in the middle of the background technology, the utility model proposes a kind of controlled adapter structure.Can realize the function of adapter, voltage-regulation is not limited by can in the mainboard loop simultaneously.

Technical solution of the present utility model is:

A kind of controlled adapter is characterized in that: comprise being arranged on first on the adapter to six limbs, also comprise first voltage source, second voltage source, the tertiary voltage source that are connected successively with the 7th, eight, nine limbs; Above-mentioned first limb is connected with the 7th limb, and the 3rd limb is connected with the 8th limb, and the 5th limb is connected with the 9th limb.

Above-mentioned first limb is connected with second pin, and the 3rd limb is connected with the 4th limb, and the 5th limb is connected with the 6th limb.

Be provided with electronic switch between above-mentioned first limb and second limb, be provided with electronic switch between the 3rd limb and the 4th limb, be provided with electronic switch between the 5th limb and the 6th limb.

The utility model has the advantages that:

1. do not need the circuit on the mainboard is changed, reduced infringement mainboard.

2. be external owing to voltage source, the voltage-regulation scope is determined by external unit, can select high precision for use, the voltage source of wide region, thus voltage-regulation is not limited by or not the mainboard loop.

3. when lacking motherboard circuit figure, still can carry out the voltage performance test to mainboard.

4. by the short-circuit plate, can realize the function of general adapter.

5. by on adapter, adding switch control, the true application testing that the internal memory module that can reduce powers on.

Fig. 1 is the utility model structural representation;

Fig. 2 adds the structural representation of electronic switch for the utility model;

Fig. 3 interconnects for first and second limb of the utility model, and third and fourth limb interconnects, the interconnective structural representation of the 5th, six limbs.

1-first limb wherein, 2-second limb, 3-the 3rd limb, 4-the 4th limb, 5-the 5th limb, 6-the 6th limb, 7-the 7th limb, 8-the 8th limb, 9-the 9th limb, 10-first voltage source, 11-second voltage source, 12-tertiary voltage source, the tested internal storage location of 13-, the 14-adapter, 15-testing host internal storage location slot, 16-electronic switch.

Embodiment

Referring to Fig. 1 and Fig. 2, on the adapter of internal memory module,, connect the two ends of the line of disconnection respectively with two solder joints with the connecting line disconnection of supply voltage and reference voltage.Be originally between two solder joints that a lead links together them, realization be the function of adapter.After the connecting line disconnection, need on circuit board, increase by three solder joints, just the solder joint among Fig. 27,8,9.These three newly-increased solder joints are used for connecting external power supply.What can see that

limb

2,4,6 connects is the grid of MOS-FET, and 1,3,5 what connect is source electrode, and 7,8,9 what connect is drain electrode.By 2,4,6 switches of controlling between 1 and 7,3 and 8,5 and 9.Promptly when on 2,4,6 voltage being arranged, conducting between 1 and 7,3 and 8,5 and 9, i.e. internal memory power supply; Otherwise turn-off i.e. internal memory power down between 1 and 7,3 and 8,5 and 9.Certainly this MOS-FET also can realize by other modes, for example voltage-controlled electronic switch, or the mimic channel built of triode.

When the voltage performance of internal memory module is tested, external digital power positive pole is linked to each other with first limb, the 3rd limb, the 5th limb among the figure, provide the required supply voltage of internal memory module work and the voltage of reference by external voltage source.Supply voltage refers to the main supply voltage of memory bar, and English code name is Vdd; Reference voltage refers to the datum on the memory bar, what be mainly used in the representative of judgement analog voltage is 0 or 1, such as, if reference voltage is 0.75V, when input voltage is 0.8V, what can think the representative of this input voltage in memory bar inside is numeral 1, and when should input voltage being 0.6V, what memory bar can be thought this input voltage representative is numeral 0; Supply voltage and reference voltage are exactly needed voltage on the tested internal storage location; And tested internal storage location refers to is exactly the internal storage location of mainboard.

First limb on the adapter is linked to each other with second limb, and the 3rd limb links to each other with the 4th limb, and the 5th limb links to each other with the 6th limb, can prevent in test process, and frequent plug damages host slot on host slot.Frequent plug just damages adapter on the internal memory adapter, after adapter damages, directly changes just passablely, and cost is low.

When the power supply electrifying situation of needs internal memory module that is virtually reality like reality, can be by on circuit board, adding electronic switch, by the voltage on second limb, the 4th limb, the 6th limb come control voltage source whether with first and third, five limb conductings.The effect that electronic switch plays is internal memory power up that is virtually reality like reality.Because do not add before adapter and the digital voltage source, internal memory is powered by mainboard.After adding adapter and external power supply, internal memory is powered by external power supply, but has done a problem like this, exists in exactly mainboard just may power on before not powering on, and does like this to cause in the test process some test coverages to be lost.So control the break-make of electronic switch by the power supply of the interior nonresident portion on the mainboard, thereby can control the break-make of powering on the tested internal memory that has connect adapter, thereby really realize in internal memory power up and the use consistent.
