Embodiment
The structure and its operation principle of the attachment means that substrate is fixed on to housing of the explanation present invention below in conjunction with the accompanying drawings.
Fig. 1 is the top view for the hollow housing 1 for being attached to substrate (not shown in figure 1).It can be seen that in shell
The both sides of the hollow inside of body 1 each offer two wedge-shaped slot 1-1, that is to say, that are opened up altogether in the hollow inside of housing 1
There are four wedge-shaped slot 1-1.It is preferred that each wedge-shaped slot 1-1 is close to one of corner of housing 1, so can more consolidate
Ground fixed substrate.
It is generally rectangular shaped that substrate is fixed on to the main body 2 of the attachment means of housing, but is opened in its insertion on housing 1
Wedge-shaped slot 1-1 side is provided with wedge-shaped afterbody 2-7, and its shape matches with wedge-shaped slot 1-1., can be to prevent by said structure
Only attachment means release after embedded wedge-shaped slot 1-1 from wedge-shaped slot 1-1, and further result in the substrate being mounted thereon
Drop or slip.
Certainly, for the person of ordinary skill of the art, it is contemplated that by above-mentioned wedge-shaped slot and wedge-shaped afterbody
Other shapes are designed as, as long as being able to ensure that attachment means can be embedded in groove without releasing.Such modification falls
Enter within protection scope of the present invention.
It can be readily appreciated that the main body 2 of attachment means is made up of elastomer, for example, rubber, nylon, styrene, vinyl chloride
Class, polyurethanes, polyamide-based etc..These modification is also each fallen within protection scope of the present invention.
Fig. 2 is the sectional view of the attachment means of the present invention.As shown in Fig. 2 in one example, the height of main body 2 can be with
It is arranged to be interference fitted with the height of lid 4 and housing 1.
In addition, the main body 2 of attachment means can offer longitudinally through main body 2 with wedge-shaped afterbody 2-7 opposite sides
Slit 2-1.Otch 2-1 can substrate 3 insert.So, substrate 3 is being sequentially inserted into the otch 2- of each attachment means
After 1, substrate 3 can relatively securely be arranged on the hollow inside of housing 1, then can cover lid 4 at the top of housing 1,
So that substrate 3 is hidden in the inside of housing 1 and from ectocine or interference.
Present inventor by finding after many experiments, if the otch 2-1 of attachment means upside and/
Or if downside offers one or more hole 2-2 along the direction parallel to substrate, the elastomeric material near otch 2-1 is on edge
The in-plane of substrate 3 is easier to move, and is less susceptible to move perpendicular to the direction of substrate 3.
Explanation is needed exist for, so-called " upside " and " downside " are the otch 2-1 institutes in fig. 2 relative to attachment means
For showing orientation, one of ordinary skill in the art can change the installation direction of attachment means in known category, hole 2-2's
Orientation will change with the change of attachment means installation direction, and this is many institute's weeks for the person of ordinary skill of the art
Know.
Fig. 3 is referred to, the figure shows stress diagram of the main body 2 of attachment means in the wedge-shaped slot 1-1 of housing 1.
It can be seen that when inserting substrate 3, chucking power is due to substrate (as shown in the filled arrows in Fig. 3) caused by otch 2-1
Fastening force between cooperation and lid 4 and housing 1 between 3 and otch 2-1 applies caused on the body 2.
Fig. 4 to 7, which is shown, to be improved to the otch of traditional attachment means so as to obtain pushing away for the technology of the present invention design
Process is led, wherein Fig. 4 is the cross-sectional view of traditional attachment means, and wherein rectangular shape is presented in otch；Fig. 5 is the present invention
Attachment means the first comparative example cross-sectional view, wherein contact surface of the otch with substrate is formed with tooth-shape structure；
Fig. 6 shows the stress of shaped cutouts in the way to enlarge；And Fig. 7 is the first preferably implementation of the attachment means of the present invention
The upper side and lower side of the cross-sectional view of example, wherein otch offers three holes respectively along the direction parallel to substrate.
As shown in figure 4, the rectangular slits of traditional attachment means can clamp substrate 3 really, but substrate 3 is heated swollen
During swollen or contract on cooling, produced frictional force can tightly act on otch 2-1 contact surface.Due to the contact table of rectangular slits
Face is relative smooth, therefore is unfavorable for stress release.
Accordingly, it is considered to otch 2-1 is made with (that is, the dentation contact of several tooth-shape structures with the contact surface of substrate 3
Position) shaped cutouts (referring to Fig. 5).By the example compared with the conventional attachment devices shown in Fig. 4, it is found that when
When substrate 3 is expanded or shunk due to temperature change, substrate 3 does not produce in the presence of frictional force with dentation contact site
It is relative to slide, but occured bending and deformation under the shear stress of frictional force.
As shown in Fig. 6 enlarged diagram, for substrate 3 in expanded by heating, main deformation direction is in the horizontal direction
Expansion, i.e. substrate 3 stretch towards the direction of arrow in Fig. 6.Now, the dentation contact site contacted in surface can bend change
Shape, (for ease of signal, the deformation extent of contact site has been exaggerated, but not shadow as shown in phantom in Figure 6 in the direction that it is deformed
Ring those skilled in the art for the understanding of the present invention).Although the contact on the upside of otch is illustrate only in Fig. 6
The deformation at position, but the deformation of the contact site on the downside of otch is similar therewith, and here is omitted.
Due to the difference in manufacture, and with the tolerance closed, the frictional force between each dentation contact site and substrate 3
Can be variant.If wherein had, the frictional force of a tooth is too small, when substrate 3 is expanded or shunk, dentation contact site with
Substrate 3 is possible to occur to slide relatively, and such case will avoid as far as possible.Therefore, inventor is in the first ratio described in Fig. 5
On the basis of example, plane is made into the dentation contact site of above and below otch 2-1 both sides so that dentation contact site is turned into square
Shape hole, in other words so that be spaced apart between rectangular opening and otch 2-1 by thin-walled.As shown in fig. 7, otch 2-1 and substrate 3
Contact surface be whole plane, rather than several points.As the present invention the first preferred embodiment, otch the upper side and lower side
Rectangular opening is arranged side by side and is partitioned into three rectangular openings by thin-walled each other.Now, due to the effect of rectangular opening, table is contacted
Face will not occur to slide relatively with substrate 3 under frictional force effect, but be occured bending and deformation by the thin-walled between each hole.This
Sample, putting on the chucking power of substrate 3 will greatly increase compared with Fig. 3, firm so as to strengthen holding of the attachment means for substrate 3
Degree.
Fig. 8 is the alternate embodiment of the attachment means in Fig. 7.Compared with the first preferred embodiment in Fig. 7, in Fig. 8
The difference of first alternate embodiment is rectangular opening 2-2 quantity.Specifically, the otch 2-1's that substrate 3 inserts is upper
Side and downside each offer three rectangular openings in five rectangular openings, rather than Fig. 7 along the direction parallel to substrate 3.Pass through
Change the quantity of rectangular opening, thus it is possible to vary the thin-walled size between rectangular opening 2-2 is appropriate so as to be carried out to the pressurized state of substrate
Regulation.Certainly, the rectangular opening of other quantity is also feasible that these modifications will all be fallen within the scope and spirit of the invention.
Fig. 9 shows the rectangular opening 2-2 in attachment means in the way to enlarge, and Figure 10 and 11 is respectively illustrated in Fig. 9
Rectangular opening 2-2 other modifications.As illustrated, compared with the rectangular opening in Fig. 9, the hole in Figure 10 is close to contact surface
One end is formed as circular shape.Compared with the hole in Figure 10, the hole in Figure 11 is formed as wineglass in one end away from contact surface
Curved flanges shape.
By changing the shape in hole, it can correspondingly change the shape and size of thin-walled between hole, it is swollen so as to change substrate 3
Deformation during swollen or contraction, and substrate 3 and the elastic deformation at incision contacts position.So, deflection difference is gone for
Occasion.
Thickness, size and the material of substrate 3 and the high-low limit of use environment temperature can all influence the expansion width of substrate 3
Degree.Due to body the deforming come the deformation of absorptive substrate by thin-walled of attachment means, therefore change the shape in hole and change whereby
Become the shape of each thin-walled, it is possible to absorb the deflection of otherwise limit.
Figure 12 and 13 be the present invention attachment means second and the 3rd comparative example cross-sectional view.It is although of the invention
The first preferred embodiment of attachment means otch 2-1 is effectively increased compared with traditional attachment means for substrate 3
Chucking power, but in order to further increase the chucking power, consider on the basis of the first preferred embodiment, it is desirable to otch 2-1 is at this
Can inwardly it be closed with less resistance at body.Therefore, otch 2-1 both sides need a relatively thin position.As shown in figure 12,
The body interior of attachment means can be made hollow shape, and the hollow bulb is connected with otch 2-1.Now, otch can
To be easier inwardly to compress, but also relatively easily outwards separate simultaneously.
Therefore, consider to separate the hollow bulb and otch 2-1 using thin-walled, in other words, in the inner side of otch or root
Connection batch layer is formed, so as to which two parts up and down of otch be linked together.So, when by inward pressure, can and scheme
12 comparative example is equally easy to inwardly compress, but when being forced outwardly, then is not easy outwards to separate.Because connection is cut
The thin-walled or batch layer of mouth root upper and lower side, can be distorted, and stretch under a stretching force under pressure.Within the specific limits,
Active force required for equal displacement is significantly different, and required pressure is smaller and pulling force is then larger.
Figure 14 is referred to, wherein showing the state of the thin-walled or batch layer stress and deformation in Figure 13 in the way to enlarge.When
Otch inwardly by compression when, thin-walled or batch layer will not be deformed only in compressed form, but in flexural deformation (as schemed
In dotted line shown in).Therefore in deformation, equal displacement is less than stretching required power.If change the section shape of batch layer
Shape, moreover it is possible to the further direction of control flexural deformation and angle, so as to obtain desired technique effect.
Following drawback be present in the rectangular opening 2-2 in Figure 12 and 13：When the width of rectangular opening is larger, body is in incision energy
Enough deformation spaces are obtained, but are easily deformed on the both sides up and down of non-incision, especially rectangular opening, cause body
Entirety deforms.On the other hand, when the width of rectangular opening is smaller, the overall deformation of body is smaller, but in the change of incision
Shape space also accordingly diminishes, and is unfavorable for the assembling of body.
Therefore, inventor is by testing it has furthermore been found that substituting single rectangle with the side opening of three distributions symmetrical above and below
Hole is a kind of fairly simple scheme.The program can either provide enough deformation in incision, while the deformation of otch, especially
It is that outside deformation will be constrained by three thin-walleds, therefore the overall deformation of body is extremely limited.
Figure 15 is the cross-sectional view of the second preferred embodiment of the attachment means of the present invention.It can be seen that connecting
In the main body 2 of device master hole 2-3 is offered along the in-plane of substrate 3.In the preferred embodiment, master hole 2-3 is presented
For the shape of regular hexagon.Although other shapes of master hole is also applied for the present invention, is found by experiment, master hole is set
The overall deformation of body can farthest be suppressed by being set to regular hexagon.
In fig.15, due to the shape that master hole 2-3 is regular hexagon, in terms of the cross-sectional direction of body, the master hole
With six sides, wherein passing through the spacing thin-walled 2-5 intervals of master between on the inside of a side on the inside of otch and otch
Open (as shown in the arrow of by-level position is in Figure 15).
In addition to the 2-3 of master hole, two are further opened with along the direction parallel to substrate 3 in the main body 2 of attachment means
Secondary side opening 2-4.As shown in figure 15, secondary side opening 2-4 is it can also be provided that the shape of regular hexagon.Therefore, in the preferred embodiment
In, two secondary side opening 2-4, which can be provided respectively therein the heart, has the position of 60 ° of angles relative to the in-plane of substrate, and
In terms of the cross-sectional direction of body, by secondary spacing thin between one of secondary side opening 2-4 side and master hole 2-3 another side
Wall 2-6 is spaced apart.
Above-named secondary hole type is controlled by changing the shape of secondary side opening between secondary side opening and master hole
The deformation that thin-walled is occurred so that the overall deformation amount of the main body of attachment means reduces.Using different suppleness and different bullets
When the material of property is to make main body, it is only necessary to which changing part-structure therein can reach desired purpose, without to master
Body is redesigned.
Furthermore it is also possible to by change the size and location of secondary side opening to adjust between two secondary side opening and master holes two
The size and shape of individual thin-walled, obtain whereby it is sufficiently large, otch open caused by resistance so that otch is easy to internal pressure
Tightly and it is not easy to expand outwardly.
Specifically, Figure 16 and 17 shows two modifications of the secondary side opening 2-4 in Figure 15, it can be seen that the two changes
Type is modified to the shape of the secondary side opening in Figure 15, wherein Figure 16 by two sides of two secondary side openings away from master hole more
A side is changed to, and four sides in six sides of two secondary side openings are changed to one section of circular arc by Figure 17.For ability
The those of ordinary skill in domain is it can be readily appreciated that such change for secondary side opening shape should all fall into the guarantor of the present invention
Within the scope of shield.
Figure 18 shows another modification of the secondary side opening 2-4 in Figure 15, it can be seen that the modification is to the secondary side in Figure 15
The size in hole is modified, and is the size less than master hole by its modification of dimension.Equally, it is such for secondary side opening size
Change should also fall under the scope of the present invention.
Although the structure and operation principle of the present invention are illustrated above in association with preferred embodiment, this technology
Those of ordinary skill in field is it should be appreciated that above-mentioned example is intended merely to explanation, and cannot function as the limit to the present invention
System.Therefore, the present invention can be modified in the spirit of claims and modification, these modifications and variations
It will all fall within the scope of required by claims of the present invention.
