Abstract
A levered handle has an elongated slot that allows the levered handle to both slide and pivot over a pivot axis. The levered handle is slid over the pivot axis to allow a notch engager to engage a notch on a memory module. Then the notch engager is forced downward as the levered handle pivots upward about the pivot axis, causing a downward force to be applied to the notch on the memory module. This forces the memory module into a memory module socket. The memory module socket requires a reduced insertion force because the notch engager on the levered handle engages the notch on the memory module and applies downward pressure. A levered handle without the elongated slot can slide along the pivot axis perpendicular to the memory module to engage the notch. Both ejection and insertion forces can be reduced.
Description
Technical field
The present invention relates to the memory module testing slot, related in particular to the test trough that realizes that the lever handle tumbler inserts with the auxiliary memory module.
The application is a common stand-by extention, it applies to have the lever handle tumbler and memory modules is pushed adapter and starts the computer main board test trough that release takes out memory modules, file in the U.S. on December 23rd, 2004 and compile 10/905, No. 276.
Background technology
Resemble the such memory modules of DIMMS (dual-inline memory modules) and be widely applied in the various systems, for example PC (PCs).Because manufacturer's profit of memory modules is more and more lower, manufacturing cost also just must reduce.By test memory module on the computer main board of having revised cheaply, rather than on the electronic assembly test instrument of costliness, carry out, can reduce testing expense.
Expansion card can insert in the memory module slot on the Standard PC mainboard, and when this expansion card bottom was inserted on the memory module slot on the mainboard, its top was equipped with another memory module slot.Expansion card can upwards lift from the mainboard surface with open memory module slot effectively, just can take out this slot more easily.
Fig. 1 shows is a memory modules expansion card between PC mainboard and the memory modules tested by mainboard, element 28 and the memory module slot 18 that is installed in an element next door are arranged on the mainboard 26, many components and parts such as integrated package, resistance, electric capacity, fan, connector and plug can be installed on mainboard, and a lot of mainboards all have 2 or 4 memory module slots 18.
Usually, memory modules 10 is directly inserted in the memory module slot 18, so that the metallic contact of metallic contact 14 and memory module slot 18 the insides closely cooperates.Yet cable and element 28 may be crowded with around the memory module slot 18, and this makes that the insertion memory modules is very difficult.It is seldom to be used on the terminal PC that module is inserted operation, and when mainboard 26 was used to the test memory module, this limiting access was problematic.
When carrying out such test by expansion card 12, memory modules 10 can be inserted easily.Metallic contact 24 on the bottom sides of expansion card 12 is to be inserted in the memory module slot 18, signal can be passed to contact in the corresponding expansion slot 20 from metallic contact 24 by the metal wire on the expansion card 12 on.
In test process, memory modules 10 is inserted in the expansion slot 20 on the expansion card 12.Because expansion slot 20 is raised up on the memory module slot on the mainboard 26 18, just can implements the taking-up and the insertion of memory modules 10 and remove.
The characteristics of some memory module slot are to use fixture that memory modules is locked in the groove.Can prevent to connect unexpected becoming flexible like this, even cause the loss of memory modules, for example, after memory modules 10 was fully inserted into, the clip 22 on the expansion slot 20 can move to snap in the recess 16 on the memory modules 10 inwardly.In order to be maintained fixed, the memory module slot on the mainboard 26 also has such clip 22.
What Fig. 2 A-B showed is the operation of the maintenance clip on the memory module slot, keeps clip 22 to be in outside rotation and away from the release position of expansion slot 20.Shown in Fig. 2 A, memory modules 10 is to be inserted into the retaining clip buckle in the expansion slot 20 of open state.When memory modules 10 was fully inserted in the expansion slot 20, recess 16 will be aligned with keeping clip 22.
Shown in Fig. 2 B, keep clip 22 to be rotated inwardly, cause the recess 16 of projection and memory modules 10 above it to mesh.This engagement can prevent memory modules 10 unexpected ejections.
Yet before maintenance clip 22 snapped in recess 16, memory modules 10 must insert expansion slot 20 fully.And memory modules 10 is inserted in the expansion slot 20 fully, the user just must apply very big strength to memory modules.
Though this slotting power may be very big, because pulling force more is better than thrust, the power of required taking-up can be more difficult.Some memory module slots have been equipped with the release device, to be used for initially taking out or to begin to take out the memory modules that has inserted.
Shown in Fig. 3 A-B is the operation of the release in the memory module slot.Keep the extension of clip 22 can be formed on the fulcrum or axle point that keeps clip 22, this extension is hidden in the expansion slot 20 usually, and the extension that keeps clip 22 is exactly the extension release 30 among Fig. 3 A-B.
As shown in Figure 3A, when memory modules 10 is fully inserted into expansion slot 20, keep clip 22 will snap in recess 16, extension release 30 is in its extreme lower position at this moment, is lower than memory modules 10.The bottom of memory modules 10 (connector) cutting edge of a knife or a sword mouth just contacts with the terminal afterbody of extension release 30.
Begin to take out memory modules 10, the user just should draw outwardly and keep clip 22, shown in Fig. 3 B.When keeping clip 22 outwards to rotate, the pivot of the extension release 30 in expansion slot 20 just upwards rotates.The afterbody of extension release 30 can upwards promote the bottom cutting edge of a knife or a sword mouth of memory modules 10 simultaneously, forces memory modules 10 to pop up from expansion slot 20.Very typically, extension release 30 is only released a little distance up with memory modules 10, and the user will draw memory modules up with its taking-up.
Because usually need bigger power to go to insert memory modules, this maintenance clip and expansion card just seem very useful.When technical staff or operator had to manually memory modules be inserted test trough, this slotting power can produce the repetitive pressure damage, maybe may damage memory bank, expansion card or mainboard tester.Usually under test or experimental situation, memory bank needed change once in per 2～5 minutes.

Embodiment
The present invention relates to a kind of improvement of memory module slot.Describe below so that those skilled in the art use and use the present invention described in the context of concrete application and its demand.Obviously, those skilled in the art can do various modifications to most preferred embodiment, and defined here basic principle can be applied among other embodiment.Therefore, the present invention not only is limited among described these embodiment, all is included within protection scope of the present invention with the corresponding to wider scope of this principle.
Present patent application has disclosed during inserting uses lever principle to act on slotting power on the memory modules to increase the user.After inserting is not the memory modules that remains on simply in the groove, and as keeping clip to do, before memory modules was fully inserted into, lever handle applied downward pressure to memory modules.Like this memory modules is inserted in the groove and just is easy to.
The inventor recognizes that further lever handle can be with one than fixed better movable pivot.Lever handle slides along rotating shaft (pivot axis), further to help the recess engagement on recess engaging-piece and the memory modules module.Especially when the user inserted the recess engaging-piece or extracts recess, lever handle slided along pivot.This lever handle rotates along rotating shaft then, and does not slide to apply slotting power.
Fig. 4 A-C is that slip memory modules lever handle applies the operation chart that memory modules is inserted power on the memory modules that will be inserted in the memory module slot, shown in Fig. 4 A, memory modules module 10 is by in the opening in the User Part ground insertion memory module slot 38.Guide groove along the side of memory module slot 38 can import memory modules 10.
Among Fig. 4 A, lever handle 32 is drawn out with away from memory modules 10, and slides so that lever handle 32 is in complete deployed position along rotating shaft 44.
Recess engaging-piece 36 is formed on the lever handle 32, and it separates with the memory modules that is inserted into memory module slot 38 when initial.During insertion, the user pushes memory modules 10 in the memory module slot 38, so that the recess 16 on the memory modules 10 is in the rightabout with same position upper notch engaging-piece 36.Shown in Fig. 4 A, memory modules also is not inserted into for 10 this moments.
Along with memory modules 10 little by little is fully inserted in the memory module slot 38, when lever handle 32 when rotating shaft 44 inwardly slides, recess 16 and 36 engagements of recess engaging-piece.If the recess 16 on the memory modules 10 is too high with respect to recess engaging-piece 36, so, the user can combine closely until recess 16 and recess engaging-piece 36 with memory modules 10 as far as possible toward being pushed down in the memory module slot 38.
Handle end on the lever handle 32 at the rightabout of recess engaging-piece 36, can be made longlyer or heavier, makes it to be shelved on naturally on aligner 35 levelling benches of a part that belongs to base plate 34.Lever handle 32 shown in Fig. 4 A obviously is in resting position.
Shown in Fig. 4 B, the user slides lever handle 32 towards memory modules 10.Elongated slot on the lever handle 32 can make lever handle 32 slide along rotating shaft 44.Along with lever handle 32 inwardly slides towards memory modules 10, the recess 16 on recess engaging-piece 36 and the memory modules 10 meshes together.
Shown in Fig. 4 C, lever handle 32 is around its pivoting point---and rotating shaft 44 upwards rotates on the base plate 34.If the user lifts the distal portion of lever handle 32, cause on the opposite side with rotating shaft 44 fulcrums to recess engaging-piece 36 move down.
Along with lever handle 12 is lifted, the bottom of recess engaging-piece 36 begins the bottom to recess 16.Along with lever handle 32 is further rotated, memory modules 10 is forced to insert further in the memory module slot 38 downwards.
After lever handle 32 was rotated to certain position, memory modules 10 can be fully inserted in memory module slot 38.Metal Contact sheet in Metal Contact sheet on the memory modules and the memory module slot 38 has electrically contacting property well.
Compare as can be known with the position of memory modules among Fig. 4 B and the 4C, along with lever handle 32 is rotated, it is more little that the distance that memory modules 10 moves down can become, because the friction together of Metal Contact sheet, the very large strength of that part of just needs that memory modules is inserted into be guaranteed their tightly combinations.Because lever principle, the power multiplication that lever handle 32 applies the user, causing recess engaging-piece 36 to be applied to force rate user on the memory modules 10, to be applied to the power of end of lever handle 32 bigger.Certainly, if the user holds the middle-end rather than the end of lever handle arm, along with the arm of force of lever is reduced, the user must use bigger power.
When lever handle 32, recess engaging-piece 36 and base plate 34 by partly or installed near the standard memory module slot, can be as embodiment of PC master they parts as the test adaptation board.Be illustrated in figure 5 as the test adaptation board that has expansion card and be used for the sliding lever handle of auxiliary memory module insertion.
Lever handle 32 when being in the release position, slides to memory modules 10 along rotating shaft 44, when memory modules 10 is inserted into memory module slot 38 proper depth, makes recess 16 engagements on recess engaging-piece 36 and the memory modules 10.Because upwards lifting lever handle 32, the user rotates around the rotating shaft on the base plate 34 44, the power that acts on the recess 16 that recess engaging-piece 36 produces makes memory modules 10 downward, thereby the Metal Contact sheet in its Metal Contact sheet 14 and the memory module slot 38 is closely cooperated.。
Only show the left end of memory module slot 38.Be installed in another lever handle 32 on another base plate 34 at the right-hand member of memory module slot 38 and force in the right-hand member of memory modules 10 with same form.Right end portion is not shown in the drawings, but can be referring to Fig. 7.
The height of support 48 and expansion card 12 should be enough to make sufficient interval or space between substrate 40 and mainboard 26, so that element 28 has enough cooled gas flow that is used for.
As shown in the figure, beam that the handle locator 35 from base plate 34 stretches out or projection can buckle in the recess on the end of memory module slot 38 well, are pressed in the upper surface of substrate 40 for 38 times with the control memory module slot.Memory module slot 38 and expansion card 12 can block substrate 40 in position firmly, and the substrate on mainboard 26 is pressed downward then, and the Metal Contact sheet 24 that resembles expansion card coincide in memory module slot.
Fig. 6 A-B is the operation chart of the lever handle on the test adaptation board.Shown substrate 40 is assembled on the mainboard 26 by support 48 and screw 49.Can use 3,4 or more this support 48, preferably utilize mainboard 26 existing holes.Lever handle 32 is operated as described above like that, and sliding along rotating shaft 44 makes recess engaging-piece 36 and recess 16 engagements.Along with lever handle 32 rotates around rotating shaft 44, recess engaging-piece 36 applies downward force on memory modules 10, forces memory modules 10 to insert memory module slots 38.Memory modules 10 is fully inserted in Fig. 6 A.
Shown in Fig. 6 B, at deenergized period, the user pushes the end of lever handle 32, and it is rotated round rotating shaft 44.Recessedly nibble 36 and upwards draw from recess 16.Along with lever handle 32 is pushed down, the bottom margin of the recess 16 on 30 pairs of memory modules 10 of recess engaging-piece applies power upwards.Very little power just can make memory modules 10 extract from memory module slot.Because maximum release force usually is the initial motion of memory modules 10, this initial release has reduced the power that the user takes out memory modules 10 fully from memory module slot 38.Then, the user along rotating shaft 44 outside sliding lever handles 32 so that recess engaging-piece 36 break away from from recess 16.The user just can take out memory modules 10 fully like this.
Lever handle 32 applies slotting power by recess engaging-piece 36, can reduce the power that the user is applied to memory modules 10.Can reduce the damage that the user is caused like this, for example repetitive pressure damage.
Along rotating shaft 44 sliding lever handles 32 make recess engaging-piece 36 better, more complete and be securely inserted in the recess 16.Along with lever handle 32 rotates along rotating shaft 44, recess engaging-piece 36 is engaging-in preferably can to prevent that in recess 16 lever handle 32 from being flicked or spin off from memory modules 10.Can cause operation to have more reliability like this.Therefore lever handle 32 can be used to the insertion of memory modules 10 simultaneously and flick.
Fig. 7 is the perspective view that has the mainboard tester of the lever handle of being convenient to the slip that memory modules inserts on the test adapter plate.The side examination program of test memory can be carried out on mainboard 26, for example the further side examination after examination of the internal memory side in the start-up course or the initialization.Memory modules generally is to be inserted into memory module slot 18 in Standard PC, rather than expansion card 12 is inserted memory module slots 18, and the top of expansion card 12 has the memory modules groove 38 of the memory modules that is used to receive pretest.
More than one memory modules 10 can be tested simultaneously.On substrate 40, can support to have second expansion card 12 of second memory module slot 38.Two pairs of lever handles 32 can be assembled on the base plate 34, every pair of recess 16 that is engaged on the different memory modules 10 that is inserted into different memory module slot 38 in advance.In another embodiment, each lever handle 32 can mesh two memory modules 10, has two memory module slots 38 that are used for every pair of lever handle 32.Opening 46 can have 4 expansion cards 12, perhaps uses two or more independently openings 46.
When base plate 34 around rotating shaft 44 and lever handle 32 during in side, be contained in the side of elongated slot on the lever handle 32 of walking around rotating shaft 44 base plate 34 shown in can being hidden.
Bar rod 72 can be formed on the substrate 40.When memory modules 10 is inserted into memory module slot 38, the heating chamber that bar rod 72 can be contained in above the memory modules is covered in (heater cover) (not shown), and heating chamber lid and substrate 40 form a heating chamber and be heated and test under the temperature that defines for memory modules 10.Heating chamber lid also can be connected through the hinge on substrate 40.
Fig. 8 A-B is the schematic diagram about another embodiment that slides lever handle that slides in vertical direction.Do not adopt lever handle is flatly slided to described memory modules, glide direction can be other direction.In the present embodiment, described lever handle slides meshing on the vertical direction in the plane of described recess with described memory modules.
Fig. 8 A is the setting vertical view that is inserted into memory module slot 38 when memory modules 10.Lever handle 50 and memory modules 10 be not on same plane, but skew.Lever handle 50 is along rotating as the rotating shaft 44 that is connected a bar bar on the base plate 58.
Lever handle 50 can slide along the rotating shaft 44 that shows as Fig. 8 A arrow.Slide that ring 56 is fixedly connected on the lever handle 50 and slide along rotating shaft 44.Lever handle 50 can slide into the release position 62 and the position of engagement 60 along rotating shaft 44.What take on retainer 52 is a part on the base plate 58, and restriction is through the finite motion of sliding ring 56 of position 60,62.
When lever handle 50 was in release position 62, conical recess engaging-piece 64 was in the outside of recess 16.Along with lever handle 50 slides into the position of engagement 60 along rotating shaft 44, conical recess engaging-piece 64 slips into recess 16 to mesh this memory modules recess.
Fig. 8 B is a front view.Conical recess engaging-piece 64 is engaged on the recess 16 on the memory modules 10.Lever handle 50 rotates in company with sliding ring 56 together around rotating shaft 44.Rotation lock handle 68 is sliding ring 56 projection on the lever handle 50, stop by basic stops 70, in case memory modules 10 from memory module slot 38, mentioned,, stop lever handle 50 excessively to rotate.
Fig. 9 is the rotation schematic diagram that memory modules is inserted into lever handle in the process.Lever handle 50 is fixed to and slides ring 56, and this slides the planar slide of ring 56 to the page or leaf of drawing, so that the recess 16 on the conical recess engaging-piece 64 engaging-in memory modules 10.Then, the user draws in the endways of lever handle 50 in position 50 ', causes it and slides ring 56 around rotating shaft 44 rotations.The handle end of this lever handle 50 rotates the downward power that produces on the opposite end that acts on this fulcrum (rotating shaft 44) up.By lever handle 50 and through the recess engaging-piece to recess 16 to the downward power that conical recess engaging-piece 64 applies, cause memory modules 10 to be pushed downwards into memory module slot 38.
When initial position 50 ', rotation lock handle (rotating stop) 68 leans against basic stops 70 step sidewalls, and when the user calibrated first and partly memory modules 10 is inserted memory module slots 38, it made lever handle 50 remain on initial position.Take out memory modules 10, the user need promote lever handle 50 ends down, to produce the power that makes progress that is applied by the conical recess engaging-piece 64 on the recess 16, memory modules 10 is discharged from memory module slot 38 lightly.Lever handle 50 further rotations can be rotated lock handle 68 and prop up basic stops 70 and stop.
