Description

A kind of on elasitic layer the connection set of fixing ornamental
Technical field
The present invention relates to the fixing device of decoration, especially with the mode fixing ornamental of folder to foamed material and other elasticity or energy flex layers.
Background technique
Be used in textile decoration thing on the automobile as those now, normally very exquisite moulding is used to reach a kind of effect of comfortable happiness.For example, yarn fabric (particularly dry goods, vinyl goods or the leathercraft that is connected with an elasticity bottom) is fixed on many positions (as seat cushion) on the elastic surface.This bottom generally is to be made of elastic material.The material of this flexible/flexibility can be foamed artificial material (is the foamed material of main material as polythene material or carbimide) or other pad materials, as traditional fine hair rubber product.In general, decoration is need on the bottom the yarn fabric nail in the V-arrangement thing or groove of bottom to be fixed on.In addition, yarn fabric is attached to " wavy " or " account shape " these nonplanar parts.
Nail need be established an adhesive tape at the nexine of decoration in the V-arrangement thing or the conventional method in the groove of yarn fabric and bottom.This adhesive tape is positioned in the interior recess that sews up or weld between the yarn fabric sheet usually.Same, the foamed material bottom comprises a wire that exposes, wire can be fixed in the groove of bottom in the process of injection moulding.So-called " arch " is made up of flexible metal ring, is used for affixed adhesive tape and wire.These rings can be independently by the instrument control as the arch ring rifle.All be fixedly connected between decoration and the bottom as each hogring, form permanent, a interface that can not dismounting.Significantly, this permanent interface is to be difficult to repair, and must very high skill in beginning interface place.In addition, because metal is easy to conduct electricity and the character of heat conduction, it is to be inconvenient to use that electroheat member is set on the seat.
Recently, decoration is fixed on the elasitic layer with the connection set that can divide, and can be repaired, and does not also need very high technical ability in the time of use.In an example, one side in the groove that is connected in elasitic layer of hook and circle and-loop fastener, the another side of fastener is connected on the internal layer of decoration.This method is reliably, and is also cheap aspect materials consumption.This will be provided with a quite wide groove on elasitic layer, to guarantee that enough engaging space are arranged between the fastener.
Another method recently comprises with a string clip and being injected in the groove of foamed artificial material.One form of this structure and another be the fixed connection apparatus of technology formerly, and disclosed patent document US/2003/0215601A1 has description in the U.S., and title is: connection set, the date is: 20/11/2003.A kind of simplified form and purposes that this file refers explicitly to this clip have description in accompanying drawing 1-3.Especially shown in attached Fig. 1 and 2, each clip 100 comprises a pair of outwards pin 102 of (face that bottom is relative with decoration), with two hook or the barbs 106 of high one deck vis-a-vis, form an injection moulding parent 104 together, one of hook-forming is led to the funnel position in room 110 on the top.Form a narrow position 112 between the hook 106, narrow 112 smaller than the width in room 110.The material of pin 102 and thickness make hook 106 can resiliently open appropriate size so that cylindrical body enters into room 110 by narrow position 112, and cylindrical body is fixed in the room 110 under the elastic force effect of hook 106 afterwards.In the method, cylindrical body is plastic cement or the metal bar 120 that is wrapped, and it is seamed in the interface of decorating between the fabric sheet 124 and 126.In this example, bar 120 by the cover 130 of non-fabric round, with suture 132 (or other mechanical connecting device) bar 120 is pressed on seam 122 bottom.The integral diameter ODB that bar 120 and cover 130 forms equals or horizontal width WC less than room 110 is arranged a bit.Therefore in use, when setter only need be pressed onto hook 106 with bar 120 (arrow 140 directions), the angled loxosis of hook portion causes pin 102 to open, make bar 120 by narrow position 112, when bar 120 passes through hook 106 fully, bar 120 just mechanically is fixed in the room 110 by hook 106, and seam 122 (facing to cover 130) makes decoration (124 and 126) partly be close to clip 110 by narrow position 112 simultaneously.
This clip comprises a pedestal 150, and it has the intersect part and a big surface area of a respective thickness, enables to act in (foamed material) primer 252 as an anchor.As shown in Figure 2, pedestal is easy to be absorbed in the groove 254.Pedestal is fixed on bottom inside, just as in injection moulding process sponge layer and base material being linked together.Representative is, clip 100 equally is contained in the bottom of groove 254 as shown in the figure, and in this mode, depressed deformation can make seam 122 sink to bottom and form the tightening force to the surface fully.
Shown in the accompanying drawing 3 is a seat cushions in the prior art file, a plurality of clips 100 with the sky of suitable degree in being fixed on groove 254.Guarantee the shape of bar 120 for successively opening of decoration with this.In the example of seat cushion or back pad, approximately need 12-30 clip 100 could form required shape.On general, the bottom bending must be severe more, and the space of clip is just more little.Above-described U. S. Patent expects that all the space of clip can be conditioned, partly, a fixing space is provided between each clip, and flexible connection set is annotated at the foamed material bottom by the space that connector forms expection between each clip and with this clip.
The clip that above prior art particularly is made of elastic material can adapt to bar 120 and be inserted into the bending deflection of expection during the room.But these clips should be able to be connected together with foamed material or other elastic material jails.So clamp material should have still suitable with the bottom characteristic that links together in long-term the use.
In the process of clip being injected bottom, clip can be subjected to making the high heat of clamp material feature damage.In addition, because clamp material will be connected together with the primer jail, may not can connect together ideally with being connected of curved section or circular arc portion.The general clamp material that goes up needs to select an equinoctial point between the adhesiveness of mechanical property and foamed material.Similarly, if a clip has been subjected to damage when mounted or afterwards, so whole sponge layer generally will be dropped as defectiveness.This is because this clip is to be embedded in chronically in the bottom, can cause very big damage to the surface of bottom especially when moving or reapposing.Naturally, by heat damage (and/or) the frangible clip that constitutes of compromise material is easy to when mounted or damage when using.
Because a kind of clip with good adhesive and lasting mechanical property is badly in need of in the existence of these defectives now, clip should be able to not destroy bottom when repairing like this.

Embodiment
Fig. 4 has described a pair of " locking-type " or " linking type " clip in a kind of structure of the present invention in detail, and each clip all is an assembly independently, and they are connected with flexible and tensile connector 412, and wherein connector 412 has detailed description below.General clip 410 can link together with the connector of any several multiple sizes, so that (as the seat cushion and the back pad of automobile) is provided with suitable connector spacing on the plastic elasitic layer.Each clip 410 is provided with a thin slice that intersects with clip, has increased surface 414 areas (limiting one " top " equally) of base bottom, and it is more firm in bottom that pedestal is annotated.Pedestal is made of polymeric material, the adhesion that it is particularly suitable for providing good and produce combination reaction with primer (for example polyurethane or based on the foamed material of carbimide) and combine.Polymer also can be used as base material, includes, but are not limited to nylon, polyester or other thermoplastic materials, and these materials have when temperature and environmental modification surpass intended scope still can keep original performance.For improving the protective in the bottom body, pedestal is provided with a plurality of through holes outside circumference, and liquid matrix also finally is cemented in by these holes 416 and reinforces in the lattice.
The pedestal of clip generally is circular in this example, also is provided with two relative plat parts on a tail end 420 and another tail end 422.The position-arresting key 430 of these plat parts can block the U-shaped folder 432 of the above connector 412 end.Pedestal two tail ends 420 and 422 plat part provide positioning mark for simultaneously the horizontal location of pedestal, particularly when not having the connector independent action.As described below, suitable mark is essential on the clip base, can align mutually after the bottom installation with groove and the decoration bar of guaranteeing clip, bottom.This plat part can also be for facilitating when using anchor clamps or apparatus for placing is packed clip into bottom automatically.
Each pedestal 414 is provided with a clip projection 450 that engages with bar in a kind of structure of the present invention.Each clip projection 450 is provided with bottom or the projection that engages with pedestal.452 extend a pair of pin 454 from the bottom.Form a room 456 that holds the decoration bar between these pin.When entering room 456 by narrow slit 458, the decoration bar to therefore can make pin 454 bending deflections with defeating.The structure of this clip projection has more deep narration below.
In this structure, the material of clip projection can be different with base material.The meaning is, this clip projection material can have the adhesiveness of comparing better intensity, elasticity (and/or) durability.The material that is fit to clip projection 450 includes but are not limited to: following material: impact improvement type nylon, and polyester, impact improvement type polyester, polycarbonate (PC), or other have the polymer of durable mechanical property.In this mode, do not needed as tradition balance between the adhesiveness in bottom and intensity, do not need all parts of clip 410 all to have good intensity, each part of clip 410 can have only character.
Owing to can be different materials, clip projection and pedestal be removable after being assembled into complete clip.Therefore, shown in the bottom view of the clip that connects as Fig. 5 connector, pedestal 414 has a center concave station 510, and concave station 510 has the keyhole 512 of a rectangle.As following more detailed description, the size of keyhole 512 is decided with bolt 514 sizes, and keyhole 512 can be put into the bolt 514 that is extended out by clip projection 450 bottoms 452.Concave station 510 and bolt 514 are suitable for relatively rotating on the position of inserting, bolt 514 has passed through to be stuck on the position behind the groove position, when bolt rotates in concave station fully (normally keyhole 512 is done 90 degree rotations relatively), the pin 454 on the clip projection 450 aligns with the two end part 420 and 422 on the pedestal.When bolt 514 rotated fully, concave station 510 had blocked another tail end of bolt 514, prevented that simultaneously clip projection 450 is pulled out from pedestal.Following narration, position-arresting key be prevent bolt when stop bit because of a careless and counter-rotational mode.
Clearly such setting makes assembling clip projection operation can be arranged in injection moulding front or back.In this mode, damaged or unnecessary clip projection can at any time be easy to be moved or be reapposed.For preventing that the liquid bottom from stopping up or infiltrate keyhole 512 and bolt 514 (therefore guarantee that clip projection can take out replacings) that concave station 510 can engage cap 520 with one and cover.In this figure, a cap is stuck on the concave station, and another then is removed.Cap 520 can constitute with any suitable material of pedestal 414 materials that comprises.Cap 520 is circular in example, also available certainly other any rational size shapes.Cap 520 comprises that one is used for that concave station 510 periphery is lived in imbrication and the boss 522 that extends out.Cap 520 comprises a columned engaging extension 524, and being used for has a mutual clamping force with the concave station inwall after inserting concave station 510.The lip shape that is fit to and other planar (not having expression in the drawings) can make extension 524 and the corresponding more convenient firm engaging of concave station inwall.The size of cap 520 is fit to allow bolt 514 can unhinderedly rotate in concave station 510.Therefore, in fact cap and pedestal can assemble earlier again and be used on the bottom.
Use different materials at different parts, whole clip uses so-called " twice shaping " injection moulding process may limit or hinder its recoverability." twice shaping " injection moulding process is that pedestal or clip projection are used first kind of material in the first time in the injection moulding room, after the first portion of clip solidifies, is full of the first portion that second kind of material will solidify in the room of injection moulding for the second time and is surrounded.In general, these two-part can be sticked together mutually on a large scale, have limited parts adhesion performance subsequently.But " twice " injection moulding process that can estimate some advanced person can make between two parts has excellent adhesion performance.The advantage of this method is to make the each several part of clip use optimal material to constitute, and forms one and has the internuncial pedestal of foamed material and the clip projection with high mechanical properties.
More than describe the general parts and the characteristic of clip one structure example, more at large described different clips now.Fig. 6 and Fig. 7 are the top view and the bottom view of pedestal 414, and they have separated with above-mentioned clip projection.Provide a relative scale view as an example and to the reader, the DB size of pedestal 414 approximately is 30 millimeters.But its size can have sizable excursion according to using.Equally, the thickness of pedestal the chances are 1-2 millimeter in this example, but sizable excursion is arranged.Pedestal center 610 is probably than high 1-2 millimeter (see figure 6) around the pedestal, for suitable material thickness 452 (see figure 4)s bottom the prop clip projection are provided.Centre bit diameter DC approximately is 15 millimeters, and 452 approximate diameter is complementary bottom the clip projection.High platform 610 parts in center have been made up for concave station 510 (see figure 7)s in base bottom surface 720.Probably there is the DR degree of depth of 1-2 millimeter bottom surface 720 to concave station 510, can hold thickness and probably be the bolt of 1-2 millimeter (514 among Fig. 5).Keyhole 512 width W K in this example the chances are 5 millimeters, can allow general wide 5 millimeters bolt enter (width of bolt is more a little bit smaller than keyhole, makes between them gapped) equally.
The last processing on pedestal 414 surfaces is the adhesives that strengthened foamed material substantially in this example.Similarly, lower surface 720 (and/or the desired place of end face) can make grid-like or the point-like line to go into more can strengthen in the foamed material bottom adhesive and anti-disconnected property in injection moulding.As detailed below, concave station 510 (see figure 7)s are included in two relative slip surfaces 730 and 732 that can allow in the keyhole 512 bolt rotates. Slip surface 730 and 732 is blocked by the high platform 740 and 742 of two stop bits, and the high platform of stop bit prevents that bolt 514 from forwarding the slip surface outside to.In this example, the stop bit platform is located at by revolving behind the keyhole 512 and turn 90 degrees the place.A pair of position-arresting key 750 and 752 is used for locating corresponding emulsus projection (seeing the emulsus projection 810 and 812 of Fig. 8 and Figure 10) when bolt rotates to the high platform of stop bit fully.Position-arresting key can prevent that with engaging of emulsus projection bolt from rotating to the outer place of stop bit.
In addition, the high platform 740 of the stop bit in Fig. 7 and 742 and the inwall of concave station 510 between a space (gap 760 and 762) is arranged.Be fit to pack into the cylindric engaging extension 524 of cap 520, this room.
Fig. 8 to Figure 10 is the clip structure that relates to now, shown in the structure of clip projection 450 of following detailed description.In these views,, clip projection 450 is separated from the pedestal that example is narrated in order to know mobility and the substitutability of representing clip projection 450 with emphasis.The clip projection comprise by two downward slopes 810 clip the top pin 454.The slope extends outwardly into the outside of pin, extends to form narrow slit 458 inwards.This narrow slit has a spacing G who is approximately the 0.5-1 millimeter when static.But the spacing of this narrow slit is changeable, and it is a pair of hook 920 that is extended out by the inboard to pin, and just slope 810 forms than lower part.The upper plane that the slope forms becomes about 30-50 degree angle AB with horizontal plane 1010 (parallel with bottom 452).This angle can be decomposed into lateral pressure (double-head arrow 1030) with a downforce (arrow 1022) of transplanting a cutting 1020 (seeing hatching), and lateral pressure makes pin 454 outwardly-bent distortion, the bar outside width OWB that allows narrow slit 458 be flared to can to make bar 1020 pass through.In this example, bar is a thickening, and by the plastics 1024 wrapped, the material that it is connected with one deck decoration at least sews up.The size at the top 1028 of bar can be pushed when bar is pressed into room 456 and be driven hook 920.In this example, the Extreme breadth WC in room approximately is the 4-5 millimeter, and height H C approximately is the 5-7 millimeter.Therefore the spacing G of narrow slit big appointment when bending deflection increases by 3 millimeters.To take dimensions all be as an example to here all in addition, and the size of all component here can both and adapt to other numerical value according to required effect and change.
Notice hook 810 tail end of the angle bigger that also had than AB.This can be decomposed into a horizontal extruding force (double-head arrow 1030) with downforce (arrow 1022) better when bar 1028 is compressed into narrow slit.
In order to make pin that better sheathed is arranged in the insertion process of bar, pin has one approximately to acutangulate the 3-10 degree inwards than lower part.In addition, between the nexine of bottom 452 and pin, be provided with a pair of little arch 1040, these little arch and can more guaranteeing to have suitable sheathed and can not make the damage that the pin 454 and the ends 452 produce fracture or other modes than lower part of acute angle arranged with reinforced bottom.In this example, the width W L (see figure 8) in the pin is approximately the 4-5 millimeter.Pin thickness T L (see figure 10) is approximately the 1-1.5 millimeter.To take dimensions all be as an example to here all in addition, and the size of all component here can both change according to utilization and the material that uses.
For the possibility breakage that prevents that better excessive pressure from causing, each pin 454 is all respectively facing to a column 850, and column 850 is provided with the general internal surface that becomes similar angle with the outer surface of pin.Common, column 850 forms a support, and this support can provide cumulative holding power to form pressure with block from foot point.The internal surface 1050 of each column 850 all is to have certain size, with the inner face bonding point of pin be the maximum deflection point of pin, it supports pin to damage to prevent pin near the bonding point.Column 850 is provided with has that reinforcement effect is outside to be leg-of-mutton entity arch 1052, is connected firmly with the intensity of guaranteeing column with clip base 452.The height of column 850 and width are variable, but should be enough to keep the firm of pin having only under the diastrophic situation.When inserting decoration, there being other possible over-stress to exist, so-called " have the hiccups " can apply the over-stress of bigger quantity in the process, " have the hiccups " process be when the injection moulding bottom clip by toward pressing down and in bottom, cooling off the clip of fixing.Column 850 is particularly resisted the over-stress that produces in the process of having the hiccups of key.
Comprise above-described bolt 514 below the bottom of clip projection, it is located on the handle 960.Handle is located at the center portion of bottom 452 in this structure, its external diameter is not more than the width of keyhole 512, can rotate to only off-position to guarantee bolt from going into the bolt mouth in keyhole.As previously discussed, the room SD of handle is consistent with the thickness of pedestal in concave station 510, is approximately the 1-2 millimeter.The end 970 of described bolt 514 is fillets, makes its easier periphery rotation in concave station 510.
Handle 960 can disconnect (as brisement) as so-called " welding " when being subjected to too much stress, make under the environmental conditions of using at some, this one or more clip and decoration disconnect or unclamp very and should be noted that, for example, an airbag must expansion below decorative sheet.One default breakdown point 1060 (representing) as Figure 10 dotted line be arranged on handle around.Breakdown point in this example is a narrow circumferential notch, but can preestablish the orientation (or other parts in connecing in pedestal and clip projection) of Material weakening on handle.In another kind of structure, weld is to be provided with circular incision or hole at handle circumference or intercooler core position, and handle is embedded in the pipeline recess.Similarly, the part of weakening can be a stalklet that simply can play suitable effect.The general part that weakens that goes up should be able to and have the skill of experiment to make optimization between installation/constant intensity and yield strength by moulding.
Figure 11 profile illustrates, and the bolt 514 of clip projection is inserted into the state of pedestal 410.Cap (520 among Fig. 5) is separated from concave station 510.Bolt rotates (arrow 1120) to emulsus projection and position-arresting key 750 and 752 junction points, when just bolt 514 engages with the high platform 740 of stop bit and 742 from going into bolt mouth position by keyhole 512 backs.Position-arresting key and emulsus projection have one " click clatter " sensation when engaging, this allows the user can feel that clip projection and pedestal have no alignment.
Shown in Figure 12 is that clip 410 is put into decoration foamed material 1222 grooves 1220 that solidify.In this example, what have only clip projection 450 is that bottom 452 is visible, and pedestal and its high portion 610 in centre effectively are immersed in the parent.In injection moulding process, use a random cap 1230 to enter in the clip to prevent too much material with being careful, cap 1230 particularly (or has the coating of anti-parent by the material of the anti-parent of tool, as teflon) to form, it can surround (shown in dotted line) with selected clip as shown in the figure fully.Cap comprises nexine position-arresting key (not having expression in the drawings), is to be formed by slope 810 outward extending tail ends 1234, is taken off in the process of injection moulding to prevent cap.In case parent solidifies fully, cap 1230 can take out with artificial or machinery.
As mentioned above, pedestal 414 of the present invention can interconnect with the connector 412 of variable-length.Figure 13 shows the connector that the variable-length bar connects.In this example, the length of axle 1310,1320,1330 is respectively L1, L2, L3.Length is predefined.The length of connector rod be several millimeters or more than.The tail end 432 of noticing each U-shaped folder is provided with a pair of Small clamp 1340 inwards, is to be used for better fastening with position-arresting key (seeing 790 among Fig. 7).The pole length (shown in dotted line) that is connected by connecting tube 1350 is unrestricted.Otch 1352 (shown in dotted line) among the figure between axle two tail ends links together and can obtain required length.In other words, connecting rod can provide big length, and stock can be divided into two sections suitable length simultaneously.Two sections available connecting tubes 1350 link together.Significantly, according to different structures multiple bar Placement can be set.
Connector in this example is about 2 millimeters by average thickness/diameter, and the cross section is that rectangle, square or circular elastic material are formed; Thickness can change according to the desired material of connector, DE and axial torsion.Base material also is suitable for connector.In case install, connector is special plug-in package.The topmost purpose of connector is the level that keeps spacing and keep clip when clip is put into bottom when parent is shaped.
Figure 14 and Figure 15 have described the clip ways of connecting in detail according to variable structure.In Figure 14, the clip 1410 of a pair of similar above-mentioned clip 410 is linked together by a fixed length bar 1420.Bar 1420 two ends are fixed in respectively on the tail end 1430,1432 of pedestal 1440,1442.Bar is integrally formed in pedestal 1440 and 1442 injection mouldings.Pedestal 1440 and 1442 is provided with relative bar 1550 and 1552, and they extend to adjacent pedestal (there be not expression among the figure) or other connectors.In general, the clip required arrangement in interval is predefined.Alternatively, this device can be used in the bar middle part of connector to change the spacing of clip.
In Figure 15, clip 1510 and an end of 1512 are provided with a position-arresting key 1520, the other end affixed tail be provided with the connector 1530 of U-shaped folder.Each clip comprises the connector and the clip of one, is connected with the clip position-arresting key that matches to form a series of clip.Notice that connector can preestablish the magnitude range of connector.For example the connector of length L 4 can link together with the clip 1512 of shorter length L 5 connectors.In variable structure, the bar of intermediate connector (as connecting tube 1350) and suitable length can allow the size of one connector not be restricted.
It in Figure 16 the varistructure of completed clip projection 1610.In the clip projection 1610 a plurality of parts with above-mentioned structural similarity or consistent.In brief, the clip projection comprises a pair of elastic foot 1620 and hook 1622 vis-a-vis, is used to fasten the plastic cement inclusion portion 1024 (shown in dotted portion, narration being arranged above) of decoration bar.Pin 1620 is extended out by bottom 1624.By the bottom 1624 excessive plastic deformation of column 1626 prevention pin 1620 that extends out, the effect of column is as indicated above.The another side of bottom is provided with handle 1630 and bolt 1632 to lock in pedestal (as Fig. 6, the pedestal 414 among Fig. 7 and Figure 12) in can rotating.Base material can be different with clamp material, is particularly suitable for embedding foamed material or his bottom of base, and clip projection 1620 is with suitable elasticity and/or is convenient to take out from pedestal when the damage.The internal layer 1640 of pin 1620 is provided with an acute angle protrusion 1650 according to this structure.As shown in the figure, acute angle protrusion 1650 from the pin internal layer than near lower part (bottom 1624) downward (facing to bottom 1624) with give prominence to inwards.Protrusion and pin/clip are integrally formed.Its thickness relatively thin (approximately 0.5-2 millimeter), width is big (with the about 2-3 millimeter of limit perpendicular distance), and length is approximately 2-5 millimeter (other length are all expected).Protrusion 1650 has some bending deflections when being close to bar cover 1024, so that the bar cover can keep can producing extra click in position and not when moving.This reason that moves may be because automobile causes passenger's vertical tremor when advancing.The crooked variable degree of this protrusion when included angle A T between the pin internal layer can determine that cover 1024 engages with protrusion 1650.The included angle A T of protrusion and size all expressly design in the position of pin internal layer in addition.Notice that this structure is provided with a pair of shockproof protrusion 1650 vis-a-vis, provide holding power on one side but specially designing single protrusion in a kind of variable structure.Similarly, can protrusion more than two be set for pin in other structures.
At last, Figure 17 one Figure 20 has represented the bigger clip base structure of variation according to the present invention's design, and socket 1720 can be provided with on one side or polygon gang socket tail end, is used for above-described a succession of clip-type.The shape and size of socket 1720 can both alter a great deal.In this structure first of pedestal (top or bottom) 1730 be provided with one by framework 1742 round rectangular aperture 1740 and bottom surface vis-a-vis 1750.In general, socket is provided with a pair of vertical surface 1760, and it is to be extended by the pedestal level break-in on first and second 1820 to form.The inlet of vertical surface 1760 is provided with the shoulder 1770 of an external narrow inner width.Shoulder in this example (can change mutually and work as greatly) forms a throat width WO who is approximately 2.1 millimeters.Width W W bigger (being at least 2.5 millimeters in this example) inside entering the mouth on the contrary.
As shown in figure 19, this routine connector 1910 is provided with cardinal principle width W SS and is approximately 2 millimeters bar portion 1920.It is provided with a wedge angle/leg-of-mutton afterbody 1930, it be generally width W SS and be provided with that a pair of acute angle AE position as shown in the figure is outward extending, rubber-like, integrally formed protrusion 1940.The width W ET of Yan Shening is bigger than WO and WS fully.So, as shown in figure 20, when afterbody 1930 passes through shoulder 1770 sockets 1720, can reply behind protrusion 1940 bending deflections (arrow 2020) inlet passage and form the angle A C littler than AE.This make the afterbody 2060 of protuberance be squeezed in shoulder 1770 in connect in the place 2030, this can prevent that socket 1720 from extracting from tail end 1930, but needs a suitable side direction and axial angle to guarantee the sheathed of connector and pedestal in addition.
Embodiments of the invention have been done to be described in detail in front.Under the situation that does not break away from the spirit and scope of the invention, also can do different the modification and additional content.For example, can anticipate significantly that clip projection and pedestal can be made up of and the clip projection can be used the dismounting mode the material of similar (or consistent).Similarly, removable clip projection can link together with other connection sets and pedestal, as the connection set of plug-type (non-rotating) device or use separation latch assembly.Therefore, the above just illustrates one embodiment of the present of invention, is not that technical scope of the present invention is imposed any restrictions.
