Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
In the embodiment of the invention, in the groove position of interpolation frame, the catch assembly is set, comprise two catch in the catch assembly, one of them catch has a rotating shaft, this rotating shaft is positioned at a side of inserting mouthful plane, place, this catch can be around its rotating shaft, between the default primary importance and the second place, rotate, wherein, if this catch is in primary importance, then its projected area on the direction of circuit board insertion groove position is more than or equal to inserting open area, if be in the second place, then it does not interfere with the circuit board of insertion groove position; Another catch in the catch assembly also has a rotating shaft, this rotating shaft is arranged on inside, groove position, the position between the air intake vent of inside, groove position, air outlet or air intake vent and the air outlet for example, another catch can be around its rotating shaft, between default the 3rd position and the 4th position, rotate, wherein, if another catch is in the 3rd position, then its in the projected area of air intake vent on the air outlet direction more than or equal to the air intake vent area, if be in the 4th position, then it does not interfere with the circuit board of insertion groove position.
Below, claiming to be arranged on a catch inserting the porch another catch that is first catch, is arranged in the groove position is second catch, and in conjunction with different situations, and the location status of first catch and second catch is described.
Do not insert under the situation of circuit board in groove position, catch assembly place:
First catch that is arranged on slotting porch, groove position is in primary importance, because the projected area of this catch on the direction of circuit board insertion groove position that is in primary importance be more than or equal to inserting open area, thereby stopped that the air-flow in the interpolation frame flow to the interpolation frame outside from inserting mouth.
If the geomery of first catch with insert mouthful identically, promptly primary importance is to be parallel to the position of inserting mouthful plane, place, and the rotating shaft of this catch is arranged on the one side of inserting mouthful, but then complete closed is inserted mouthful, avoids windage loss in the interpolation frame to outside; If the area of first catch is bigger, greater than the area that inserts mouth, then primary importance not with insert a mouthful place plane parallel, but can have certain included angle with an insertion mouthful plane, place, can guarantee that its projected area on the direction of circuit board insertion groove position is more than or equal to inserting open area, thereby also but complete closed is inserted mouth, avoid the windage loss in the interpolation frame to arrive outside, and, can also make this catch at circuit board when inserting mouthful insertion groove position, only need the short stroke of rotation can arrive the second place.
Second catch that is arranged on inside, groove position then is in the 3rd position, since second catch that is in the 3rd position in the projected area of air intake vent on the air outlet direction more than or equal to the air intake vent area, thereby stopped that the air-flow from air intake vent passes through in this groove position, reduce the air flow rate in the vacant slot greatly, guarantee the air flow rate demand in other non-vacant slots, avoid the air-flow short circuit.
If the geomery of second catch is identical with air intake vent, promptly the 3rd position is the position that is parallel to plane, air intake vent place, and the rotating shaft of this catch is arranged on one side of air intake vent, but complete closed air intake vent then avoids air-flow to flow in the vacant slot; If the area of second catch is greater than the area of air intake vent, then the 3rd position not with air intake vent place plane parallel, but can have certain included angle with plane, air intake vent place, can guarantee its in the projected area of air intake vent on the air outlet direction more than or equal to the air intake vent area, thereby also can seal air intake vent, avoid air-flow to flow in the vacant slot, and, can also make when this catch first catch drives rotation down, only need the short stroke of rotation can arrive the 4th position.
When having circuit board to insert in groove position, catch assembly place:
First catch that insert mouthful the enclosed slot position can be under the promotion of the circuit board of insertion groove position, in changeing the axial groove position, it rotates, and contact and drive second catch around the rotating shaft of this catch rotation with second catch, be in the second place and the 4th position respectively until two catch, promptly two catch all do not interfere with the circuit board of insertion groove position, make circuit board can be inserted in this groove position, and guarantee from this groove position, to flow through from the air-flow of air intake vent.
Wherein, the thickness of first catch and second catch is all unsuitable excessive, interferes with the circuit board of insertion groove position avoiding.For example, even if the second place is perpendicular to the position of inserting mouthful plane, place, if but the thickness of first catch is excessive, and its projection on the circuit board direction of insertion then may overlap with the insertion mouth, thereby making circuit board to insert, also is like this for second catch.
As seen, sealing was not inserted mouthful and is stopped air-flow from air intake vent when above-mentioned catch assembly can insert circuit board in the groove position, and can guarantee that circuit board is inserted in the groove position smoothly.And preferably, two catch are that area is big, the less thin slice of thickness.
In the practical application, realize that first catch drives the rotation of second catch, only need guarantee not insert under the situation of circuit board in groove position, catch assembly place two sides that catch is not connected with rotating shaft, the i.e. free side of two catch is positioned at the same side than separately rotating shaft and gets final product.For example, do not insert under the situation of circuit board in groove position, catch assembly place, if the free side of first catch is positioned at the side of its rotating shaft near heat abstractor, then the free side of second catch also need be positioned at the side of this catch rotating shaft near heat abstractor, like this, when first catch rotates in the groove position, can bump with the edge of the free side of second catch, second catch is produced an impulse force, as a rule, the edge of the free side of second catch can be for not being parallel to the regular planar of the second catch rotating shaft fully, thereby act on impulse force on second catch, on the second catch rotating shaft tangential direction, can produce a component, thereby can make second catch around its rotating shaft rotation.
Above-mentioned situation is a kind of feasible program.In the practical application, also can adopt other schemes, the impulse force that when only needing assurance first catch to rotate in the groove position second catch is produced can produce a component on the second catch rotating shaft tangential direction, can guarantee that second catch can rotate under the drive of first catch.For example, matched in clearance is adopted in second catch and its rotating shaft, like this, when first catch rotates in the groove position and during impulse force that second catch is produced, because second catch and its rotating shaft matched in clearance, thereby can produce shake, make free side to be offset certain angle, thereby make the impulse force that acts on the free margins edge can produce the component on the second catch rotating shaft tangential direction around its rotating shaft.
As seen, above-mentioned catch assembly can be when preventing that windage loss from arriving outside the interpolation frame, the traffic demand of non-vacant slot is flowed through, guaranteed to the flow that can also reduce vacant slot greatly, avoiding the air-flow short circuit, thereby improved the radiating effect that is inserted into the circuit board in the interpolation frame.
Below, identical with air intake vent in conjunction with instantiation with the shape shape and the area identical with area, second catch of first catch with the insertion mouth, technique scheme is elaborated.
Fig. 3 is the view when the catch assembly in the interpolation frame is empty in the groove position in the embodiment of the present invention.Need to prove that the angle of putting of interpolation frame is different from Fig. 1 as shown in Figure 3, in the interpolation frame as shown in Figure 3, circuit board need be inserted in the groove position 10 perpendicular to level side.
As shown in Figure 3, be provided with catch assembly (one group of catch assembly only is shown among Fig. 3) in groove position 10, this catch assembly comprises catch 21 and catch 22.
Do not insert circuit board in this groove position, catch assembly place 10, promptly this groove position 10 is empty.
The insertion mouth 110 place plane parallel of groove position 10 are in vertical plane, one side of catch 21 is provided with a rotating shaft 210 in parallel, the two ends of rotating shaft 210 are connected to the same side on the both sides up and down of groove position 10, make catch 21 vertically be installed in insertion mouth 110 places of this groove position 10 by its rotating shaft 210, and be parallel to and insert a mouthful plane, 110 place, thereby sealed insertion mouth 110, can avoid flowing out to the outside from inserting mouth 110 through the air-flows in the groove position 10.
Wherein and since the shape and size of the catch 21 in the present embodiment with insert mouthfuls 110 identically, thereby the position that is parallel to the plane of inserting mouth 110 places is default primary importance.
The air intake vent 101 place plane parallel of groove position are in horizontal plane, one side of catch 22 is provided with a rotating shaft 220 in parallel, the two ends of rotating shaft 210 are connected to the same side on both sides, air intake vent 101 front and back, make catch 22 be installed in air intake vent 101 places of 10 inside, groove position by its rotating shaft 220 levels, and be parallel to plane, air intake vent 101 place, thereby sealed air intake vent 101, made air-flow to flow in the groove position 10 of not inserting circuit board from air intake vent 101.
Wherein, because the shape and size of catch 22 in the present embodiment are identical with air intake vent 101, thereby the position that is parallel to plane, air intake vent 101 place is and presets the 3rd position.
Fig. 4 is the vertical view of the catch assembly when the groove position is for sky in the embodiment of the present invention.As shown in Figure 4, be with a torsion spring 211 in the rotating shaft 210 of catch 21, torsion spring 211 is 10 inboard and be stiff end 2111 perpendicular to an end that inserts mouthful plane, 110 place towards the groove position, can be fixed in the groove position 10; Torsion spring 211 is towards catch 21 and to be parallel to an end that inserts mouthful plane, 110 place be free end 2112, is positioned at catch 21 and contacts towards a side of 10 inside, groove position and with catch 21.
In Fig. 4, torsion spring 211 in a state of nature, its stiff end 2111 and free end 2112 is vertical mutually, making is not having under the situation of external force, catch 21 can be parallel to and inserts mouthful plane, 110 place and mouth 110 is inserted in sealing.
In the present embodiment, suppose that the second place is the position perpendicular to insertion mouthful plane, 110 place, the 4th position is the position perpendicular to plane, air intake vent 101 place.
If there is circuit board to insert, then this circuit board can apply a thrust in groove position 10 to catch 21, make catch 21 around its rotating shaft 210 to the inner rotation in groove position 10, and the free margins of catch 21 can contact with the free margins of catch 22, drives catch 22 to groove position 10 inner rotations.
For the ease of catch 21 when rotated, can relatively easily drive catch 22 rotations, end near catch 21 on the free margins of catch 22 can be provided with a gap 221, referring to Fig. 5, catch 21 is when rotating perpendicular to the position of inserting mouthful plane, 110 place, can contact with the gap 221 on the free margins of catch 22, and promote catch 22 to position rotation in rotary course perpendicular to plane, air intake vent 101 place by the impulse force that catch 21 is produced.Preferably, gap 221 edges can also have a chamfering (not shown), can make to act on impulse force on the chamfering, have the tangential component of 220 directions around the shaft, thereby promote catch 22 to the position rotation perpendicular to plane, air intake vent 101 place.
End near catch 21 on the free margins of catch 22 can also be provided with a crimping 212 towards 10 inside, groove position, referring to Fig. 6, catch 21 is when rotating perpendicular to the position of inserting mouthful plane, 110 place, can contact with the crimping 222 on the free margins of catch 22, the momentum effect that catch 21 is produced in rotary course can produce the tangential force of 220 directions around the shaft on crimping 222, thereby promotes catch 22 to the position rotation perpendicular to plane, air intake vent 101 place.
The vertical view of the catch assembly when Fig. 7 is non-NULL for groove position in the embodiment of the present invention.As shown in Figure 7, when circuit board is inserted into inside, groove position fully, catch 21 is perpendicular to inserting a mouthful plane, 110 place, and torsion spring 211 is compressed, and has minimum angle between its free end 2112 and the stiff end 2111; Catch 22 is parallel to vertical plane under the drive of catch 21, promptly vertical with plane, air intake vent 101 place.
View when Fig. 8 is non-NULL for the catch assembly in the interpolation frame in the embodiment of the present invention in the groove position.(circuit board of not shown insertion) as shown in Figure 8, catch 21 can guarantee that perpendicular to inserting 22 on a mouthful plane, 110 place, catch perpendicular to plane, air intake vent 101 place the insertion of circuit board and air-flow enter groove position 10 from air intake vent.
At this moment, if in groove position 10, extract circuit board 50, then owing to torsion spring 211 is compressed the elastic force that produces, catch 21 can be back into by the free end 2112 of torsion spring 211 and be parallel on the position of inserting mouthful plane, 110 place, thereby mouth 110 is inserted in sealing once more; Catch 22 also can be got back on the position that is parallel to plane, air intake vent 101 place after its rotating shaft 220 rotations, thereby seal air intake vent 101 once more then owing to action of gravity.
In the embodiment of the present invention, torsion spring 211 also can replace with the elastic construction that other have similar structures.
In the practical application and since interpolation frame put the angle difference, thereby the catch assembly to put angle also different thereupon.No matter but how interpolation frame is put, if the arbitrary catch in the catch assembly, can interpolation frame become empty back by action of gravity get back to automatically be parallel to insert mouthful or the position on plane, air intake vent place (for example, insert mouth or plane, air intake vent place perpendicular to horizontal plane, then catch can be from being parallel to the position of horizontal plane, be rotated down position, promptly be parallel to the position of inserting mouth or plane, air intake vent place perpendicular to horizontal plane; Perhaps, insert mouth or air intake vent place plane parallel in horizontal plane, then catch can be from the position perpendicular to horizontal plane, be rotated down the position that is parallel to horizontal plane, promptly be parallel to and insert mouthful or the position on plane, air intake vent place), for example then do not need to be provided with elastic constructions such as torsion spring in the rotating shaft of this catch; If catch can not be got back to automatically to be parallel to and insert mouthful or the position on plane, air intake vent place, elastic constructions such as torsion spring for example can be set in this rotating shaft then.
As seen, catch 21 is provided with torsion spring 211 owing in its rotating shaft 210, thereby can seal insertion mouth 110 automatically without any need for external force after groove position 10 becomes skies; And since plane, air intake vent 101 place perpendicular to horizontal plane, and rotating shaft 220 is arranged on the lower surface in the groove position 10 and is parallel to horizontal plane, therefore, catch 22 also can be after groove position 10 becomes sky, under action of gravity, rotate on the position perpendicular to plane, air intake vent 101 place, promptly be parallel to horizontal plane, thereby seal air intake vent 101 automatically, it is simple to make that above-mentioned catch assembly uses, and has advantages of high practicability.
In the embodiment of the present invention, catch 22 also can not be arranged on air intake vent 101, can also be arranged on one side of air outlet 102 of groove position 10; Perhaps be arranged on the optional position between air intake vent 101 and the air outlet 102 and guarantee that rotating shaft 220 aligns with same one side of air outlet 102 with air intake vent 101.Like this, if the shape and size of catch 22 are identical with air intake vent 101, still can avoid flowing out through groove position 10 and by air outlet 102 from the air-flow of air intake vent 101.
From above-mentioned execution mode as seen, owing in the groove position, be provided with the catch assembly, thereby do not insert under the situation of circuit board in groove position, catch assembly place, catch 21 is parallel to the plane, insertion mouth 110 place of groove position 10, thereby can seal the insertion mouth 110 of this groove position 10, thereby prevent that windage loss in the interpolation frame is to outside; The catch 22 that is arranged on 10 inside, groove position then is parallel to the plane, air intake vent 101 place of groove position 10, thereby can stop that the air-flow from air intake vent 101 passes through in this groove position 10, thereby can reduce the air flow rate in the vacant slot greatly, guarantee the air flow rate demand in other non-vacant slots, avoid the air-flow short circuit.
Therefore, catch assembly in the above-mentioned execution mode can prevent that windage loss from arriving outside the interpolation frame, the traffic demand of non-vacant slot is flowed through, guaranteed to the flow that can also reduce vacant slot greatly, avoiding the air-flow short circuit, thereby improved the radiating effect that is inserted into the circuit board in the interpolation frame.
