Description
Background of the present invention
The field of the invention
The present invention relates generally to a kind of adapter that is used for connecting optical fiber, particularly a kind of adapter that helps panel type to install.
Prior art
Optical Fiber Transmission is normally finished by an optical fiber component, and described optical fiber component comprises one section optical fiber and cross tie part with certain-length, and described cross tie part comprises that two terminate on the described optical fiber and subsequently by one female-connector that female adapter cooperates.This cross tie part helps the test carried out along cut cable, changes route, and can help to change the floor plan situation of interior of building.Especially at a kind of optical fiber to the applicable cases of desktop, described transmission is normally finished by a duplexing cross tie part, that is, described cable comprises two optical fiber and corresponding single worker's connector, and each adapter is connected to each other and forms two (duplex) interconnection together.
Two kinds of attachment unit interface that are used for data and telephonic communication system are arranged usually, and their title is ST and SC.Described ST is a propelling/twistlock formula interface.Most duplexing ST adapter by two (2) identical, rectangular substantially and body that weld together forms.Adapter is installed by the opening on the plate of an ellipse or rectangle, screws in then in the threaded hole of (both sides of described opening) on the described panel by the screw that uses some to pass the mesopore (clearance hole) in the described adaptor body mounting flange earlier subsequently and is fixed on the described panel.The single worker's adapter of described ST is cylindrical, and required anti-verticity typically uses one (or a plurality of) and is positioned at the smooth part of described cylindrical installation surface and " D " (or " two-D ") the shape opening on the corresponding plate is finished.
Described SC only is a kind of pusher connector.Except the breech lock of fixing usefulness, there is not locking mechanism, it is on the throne to prevent possible throw out of gear phenomenon being connected and fixed that this breech lock engages a connector.Because the difference of intrinsic inside coupling (intramating) is also different with the device that each adapter links to each other with a panel.Described SC adapter rectangular shaped, therefore, the board-like opening that described SC adapter is used is rectangular shaped correspondingly also.Described SC adapter rectangular shaped, and usually by use some be connected on the adapter, independent, " folder " be installed and be fixed in the opening (its size is bigger than the opening on the plate that is used for ellipse/rectangle ST) of the plate of a rectangle through the metal (normally stainless steel) of the mold pressing and the processing that is shaped.The design of described installation folder is such: on each side of described adapter a holder is arranged, and when described adapter passes opening on the described plate, each flexible portion that the keeper of folder is installed can curve inwardly, and after this flexible portion passes the thickness of the opening on the described plate, just get back to its original, external position suddenly.In this position, folder is installed can be held in described adapter clip in the described panel.The installation method of another kind of SC adapter is similar to one of ST mounting means, promptly adopts some to pass described adapter earlier screw with the mesopore in the flange is installed, and is screwed into subsequently that the interior respective screw hole of described panel installs.
Because mounting means is different, therefore, the manufacturer of this product must get product design and not only comprise that one is used for the opening on the plate of ST but also comprises that one is used for the opening on the plate of SC.The opening of making on two kinds of dissimilar plates has increased manufacturing cost, and has increased stock's requirement and complicacy.Therefore, obviously be necessary the adapter of prior art is improved, so that its only needs to use a kind of opening of single plate.
Another problem that exists in the prior art is to use metal that folder is installed SC type adapter is installed on the described panel.These metals are installed folder has increased manufacturing cost, and the fabricator also needs to increase assembly and stock.

Fig. 3 is the side view of an adapter, and described adapter to be numbering 20 total expressions, and it is to be used in the opening of plate of the standard that is installed in.Described adapter comprises four first interface ports 22.In the embodiment shown in fig. 3, first interface is ST.Described adapter comprises two adaptor bodies 20 ' and 20 ".Adaptor body 20 " comprise two ST ports 22 that link to each other with flange 24.Adaptor body 20 ' comprises two ST ports 22 that link to each other with block 28, and block links to each other with flange 26.Block 28 comprises that one is used for holding the groove 30 that a metal described above is installed folder.Two adaptor bodies 20 ' and 20 " be connected together and form adapter 20 (before weld job, a pair of middle sleeve being assemblied in described two bodies) with supersonic welding.Block 28 is rectangular, and have certain size with the plate of one second interface adapter on opening adapt.In the embodiment shown in fig. 3, second interface is SC.Rectangle block 28 can be packed ST-ST adapter 20 in the opening on the plate identical with the SC adapter.Like this, the fabricator just can make the panel of the opening with identical plate, and still is applicable to the installation of SC or ST adapter.
Fig. 5 shows the stereographic map of a kind of modification of Fig. 3 and adapter shown in Figure 4.Being used for accepting groove 30 that traditional metal installs folder is substituted by with the integral type of numbering 40 total expressions folder being installed.Installation folder 40 is formed on the place, one or both ends of block 28, and is an integral body with block 28.Install folder 40 comprise two with adaptor body surface elastic part 42 and 42 ' at angle, as shown in Figure 6.Each elastic part 42 and 42 ' first end and described adaptor body are an integral body.Each elastic part 42 and 42 ' second end include a retaining part or retained part 44 and 44 '.Retaining part 44 and 44 ' is basically parallel to the surface of described adaptor body.The folder 40 resilient clips of preferably being made by molded polymer are installed.When described adapter inserted in the opening of a plate, elastic part 42 and 42 ' was towards block 28 deflections, and after elastic part 44 and 44 ' was crossed the thickness of panel, they just got back to their original position so that described adapter is remained in the described panel.As shown in Figure 7, also some can be installed clamping in SC type adaptor body, thereby no longer need metal clip.Certainly, also the adapter of other any type can be molded as and comprise that all integral types installs folder, thereby no longer need to press from both sides with independent installation.
Fig. 8 one keeps the stereographic map of the part of breech lock with the duplex of numbering 50 total expressions.Duplex keeps breech lock 50 to comprise that two single workers that coupled together by a connection piece 54 keep breech lock 52.The working method that single worker keeps breech lock 52 is identical with the working method of the traditional maintenance breech lock 10 shown in Fig. 2 A-Fig. 2 C.The width of web member 54 can be less than the width that keeps breech lock 52, thereby forms a groove 62 in each duplex keeps the side of breech lock 50.Each keeps breech lock 52 rectangular substantially, and forms an inclined-plane 56 in each corner.Can keep breech lock 52 thereby form two single workers with making bulk (obstruction is fallen) with web member 54 mould parts corresponding, that be used for duplex maintenance breech lock 50.
Each keeps the surface of breech lock 52 to comprise all duckpin 58 and all hole 60.Duckpin 58 and hole 60 can make each duplex keep breech lock to align.If keep the mould of breech lock to change to save web member 54 to being used for described duplex, then duckpin 58 and hole 60 just can make single worker keep breech lock to align.All duckpins 58 are formed on each upper left side and zone, lower right of keeping breech lock.All holes 60 are formed on each upper right side and zone, lower left of keeping breech lock.This set just can make duplex-duplex or single worker-single worker keep breech lock to match when each keeps breech lock to be a plurality of orientation.Certainly, also can use other duckpin and hole, so that duplex or single worker keep breech lock to align.
Fig. 9 is arranged on the rear view that a duplex with the duplex adapters body interior of numbering 70 total expressions keeps breech lock 50.Described duplex adapters body has one and is used for accepting the opening 74 that duplex keeps breech lock 50.Opening 74 comprises two juts 72 that stretch in the opening 74 and be arranged on groove 62 inside in the duplex maintenance breech lock 50.Perhaps, adaptor body 70 can be undertaken on two unidirectional maintenance breech locks in the opening 74.
Figure 10 is the stereographic map of described another embodiment of adapter.Described adapter to be numbering 100 total expressions, and is made up of two identical adaptor bodies 102.Optical fiber and those optical fiber that first interface connector is housed that embodiment shown in Figure 10 can be equipped with those first interface connector couple together.In the embodiment shown in fig. 10, first interface is ST, and therefore, each adaptor body includes all first interface port 110.Each adaptor body includes a block 106, and described block has a suitable outside dimension so that can be installed in the opening on one second interface board (for example SC).In the embodiment shown in fig. 10, each adaptor body includes a flange 108, still, should be understood that, that each adaptor body can not have flange yet.
Adapter 100 also comprises all the sleeve pipe 112 that a connector ring is undertaken in each end and each ring is aligned.Each sleeve pipe 112 is placed in sleeve pipe clamper 114 and 116.Sleeve pipe clamper 114 is one the first interface sleeve pipe clamper of folder to be installed, and sleeve pipe clamper 116 is one to have all the first interface sleeve pipe clamper that folder 118 is installed.Folder 118 is installed is an integral body with sleeve pipe clamper 116.The end that folder 118 is installed comprises one towards the jut 120 that leaves the direction extension that the folder body is installed.Jut 120 has a conical surface 124 and a flat surface 126.In another embodiment, the surface 124 have a kind of circle, bowed shape.Sleeve pipe clamper 116 and folder 118 is installed is made by a kind of resilient material (for example plastics), therefore, folder 118 is installed can be bent, and then gets back to its virgin state.Each opening 128 is arranged in each adaptor body 102, is used for accepting installing pressing from both sides 118.Folder 118 is installed is had a certain size, like this, when adapter 100 is assembled, can press from both sides in all openings 128 that are positioned in the adaptor body installing.
Figure 11 is the stereographic map of the adapter 100 that assembles.Adapter 10 is with each adaptor body 102 being got up with ultrasonic soldering and assembling.The energy drag device is arranged on each adaptor body 102, and this will be described specifically hereinafter.As shown in figure 11, folder 118 is installed and is positioned at adapter two intrinsic openings 128.Figure 15 clearly show that this feature.Being formed on the lip of installing on the folder 118 122 can seal up each opening 128, prevents that pollutant (for example dust) from entering in the adapter 100.When adapter being installed on the panel, the conical surface 124 of jut 120 touches with the side edge of plate opening.When adapter 100 is pushed to described panel, folder 118 is installed just towards the interior deflector of adapter 100.When conical surface 124 is crossed the edge of described panel, folder is installed is got back to its rest position.Interference between jut 120 and the flange 108 can prevent that adapter 100 from moving into or shifting out described panel.Flange 108 is positioned on the back side of described panel, therefore, can provide a kind of installation of feeling attractive in appearance made us.If take off adapter 100, the user can promote each jut 120 towards adapter 100, and each jut 120 just can leave described face plate edge like this.
118 be installed on the described grip sleeve by folder will be installed, the length of described installation folder with embodiment illustrated in fig. 6 in compare just longer.Like this, increase, just can better control the required acting force of the opening (when clamping some installations in the adapter) that adapter is inserted plate because the length of folder is installed.When as shown in Figure 6 some being installed folder and be formed on the described adaptor body, the length that folder is installed is obviously shorter, so just need one bigger adapter insertion force.
Figure 12 one is used for connecting the exploded perspective view of the adapter 130 of the optical fiber that one second interface connector is housed.In the embodiment shown in fig. 12, second interface is SC.Adapter 130 comprises two identical adaptor bodies 132.Some sleeve pipes 112 are set, when inserting each connector ring in each sleeve pipe 112 each connector ring are aligned with box lunch.Two sleeve pipe clampers 131 and 133 have also been used.Sleeve pipe clamper 131 is one to have the second interface sleeve pipe clamper that some install folder.Sleeve pipe clamper 133 is second interface sleeve pipe clampers without any the installation folder.Two sleeve pipe clampers 131 and 133 all comprise the finger 136 that some can tightly be clamped each second interface connector.Similarly, each adapter 132 includes second interface port 138 that some are used for accepting one second interface connector.Each installs folder 118 is similar with those installation folders that the above Figure 10 of combination and Figure 11 describe.
Figure 13 is the stereographic map of adapter shown in Figure 12 after assembling.As described previously, each installation folder 118 is positioned at each opening 128.Be formed on each lip 122 of installing on the folder 118 and can prevent that pollutant from entering in the adapter 130.Adapter 130 is installed in the opening of plate in a kind of and above identical mode described in conjunction with Figure 11.
Figure 14 is an exploded perspective view that is used for the adapter 140 that optical fiber that will one first interface connector be housed and the optical fiber that one second interface connector is housed couples together.Adapter 140 is made up of above those members in conjunction with Figure 10-Figure 13 description.Some are installed folder 118 and are arranged on the second interface sleeve pipe clamper 131.Figure 15 is the stereographic map of the adapter 140 through preparing.Because each is installed folder 118 and is positioned on the second interface sleeve pipe clamper 131, therefore, the first interface adapter body 102 will extend through the opening of described plate.
Figure 16 is used for the exploded perspective view of the adapter 150 that optical fiber that will one second interface connector be housed and the optical fiber that one first interface connector is housed couples together.Adapter 140 is made of above those members of describing in conjunction with Figure 10-Figure 13.Each is installed folder 118 and is arranged on the first interface sleeve pipe clamper 116.Figure 17 is the stereographic map through the adapter 150 of assembling.Because each is installed folder 118 and is positioned on the first interface sleeve pipe clamper 116, therefore, the second interface adapter body 132 will extend through the opening of described plate.
As from Figure 10-Figure 17, can seeing, all the four kinds combinations that an importance of the present invention is an adapter (first interface-first interface, second interface-second interface, first interface-second interface, second interface-first interface) can utilize a plurality of global facilities to assemble.The present invention has adopted one first interface (ST) adaptor body, second interface (SC) adaptor body and four sleeve pipe clampers, thereby just can provide possessive construction described above.So just manufacturing cost can be reduced, and the kind of the parts that manufacturer need lay in can be reduced.In addition, all these four kinds of structures can be arranged on flange 108 on the back side of described panel, thereby a kind of comfortable installation attractive in appearance of making us feeling can be provided.
Figure 18 is the stereographic map of another kind of second interface adapter 152.Each fiber adapter all has one or two keyway, described keyway can by with described connector that the adapter keyway is meshed on key and have constant orientation with respect to matching connector (connector).When being installed on these adapters on one panel, wish that these keyways can have identical orientation all the time, and wish that this orientation is such direction, facing to the people that a connector and each adapter are matched mutually (therefore it can make each keyway, this people described connector that must align, thereby each key is meshed with each keyway).
The assembly crewman of manufacturer will be orientated (when matching mutually with each adapter keyway according to connector-retainer, the position that each adapter will be faced) towards a certain direction with each keyway of adapter.This is a kind of orientation by means of range estimation, therefore, the phenomenon of assembling towards the opposite way round accidentally will occur.
In order to prevent the mistake assembling, adaptor body 152 comprises that one forms groove 154 on its outer surface, is used for accepting a complementary protuberance part that is formed on the plate opening.So just can guarantee adapter 152 with a kind of suitable orientation positions in described plate opening.Usually, the suitable orientation of adapter 152 is such, that is, each the interior keyway 156 of each port that is formed on the second interface adapter body 152 is visible.As a result, can only described adapter be inserted in the described plate opening towards an orientation.Certainly, adapter 152 also can be fit into one does not have in the panel of a jut.
Figure 19 is the stereographic map of the part of adapter assembly 160, and shows another key character of the present invention.In the process of making adapter, each adapter normally assembles at a worker station earlier, and is sent to another worker station subsequently, there adaptor body is connected together with supersonic welding.In prior art, because each member misalignment that may separate or become in transportation, therefore, the operation that the adapter that part is assembled transports is trouble just.As shown in figure 19, because each opening 128 that the jut 120 of folder 118 is positioned at the first interface adapter body 102 is installed, therefore, having the second interface sleeve pipe clamper that folder 131 is installed can be clamped together part adapter assembly 160.This can prevent that each member of described part adapter assembly is moved or separate in the process that is transported to a welding region.Therefore, transporting and manufacturing becomes more convenient.This subassembly can also be put in storage earlier, its advantage is that assembling process is more advanced.Though shown in Figure 19 is a kind of first interface-second interface adapter subassembly,, should be understood that, that all adapters all are holistic installation folder with each sleeve pipe clamper and have this advantage because of having used.
Figure 20-Figure 23 shows another importance of the present invention.In order to produce all adapter configurations of the present invention, need four different sleeve pipe clampers.Various sleeve pipe clampers are: install second interface (Figure 20) of folder, install folder first interface (Figure 21), have second interface (Figure 22) that folder is installed and have first interface (Figure 23) that presss from both sides is installed.All these sleeve pipe clampers all are with using inserts in the described mould, being made by same mould.Can make as shown in figure 22 the described second interface sleeve pipe clamper that each installs folder that has without any the described mould of inserts.170 places clog with some inserts are embedded if described mould is in the position, and the result just can make the second interface sleeve pipe clamper that folder is not installed as shown in figure 20.172 places clog with some inserts are embedded if described mould is in the position, and the result can make the first interface sleeve pipe clamper that folder is installed that has as shown in figure 23.170 and 172 places are clogged by some inserts are embedded if described mould is in the position, and the result can make the first interface sleeve pipe clamper that folder is not installed as shown in figure 21.Owing to only need a mould, therefore, made things convenient for manufacture process.
Now please consult Figure 10 again, each adaptor body 102 includes energy drag device 103,105 and is used for accepting the opening 101,107 of the energy drag device on the adaptor body that is complementary.Term " energy drag device " is the part of raising that is used for describing a polymeric member, its pack into recess of respective shapes of the component inside that is complementary, and described structure can be clamped together described two members after the ultrasonic soldering operation.Traditional energy drag device is made into straight, thin " wall " or a cylindrical columns shape.Intensity that a this traditionally shaped shortcoming is ultrasonic soldering and described two member tensions, anti-pushing away or poor-performing that antitorque commentaries on classics separates.
Each energy drag device 103 and 105 is positioned at described adaptor body lip-deep first by one and raises part and be basically perpendicular to described first and raise second on the adaptor body of part and raise part and constitute.Described first and second raise part contact each other.In the embodiment shown in fig. 10, energy drag device 103 and 105 is L-shaped, thereby the weld strength that can obtain to add, this is because its surface area increases, and to one perpendicular to the plane of L shaped vertical leg in applied force have the resistibility of increase, in the actual use of adapter, be the most incident in this side's upward force.The traditional adapter of manufacturing at present is relatively poor for the resistibility from the acting force of this direction.Though the described energy drag device shown in the figure is L-shaped,, should be understood that, and can also comprise T shape and X-shaped with different alignment so.
Use L shaped energy drag device that some other benefit can also be provided.When each adaptor body is welded, be formed on each adaptor body all described L shaped energy drag device half hitches altogether, with at the inner I-shape construction that forms of described adapter through assembling.This and an I-beam are similar, can improve the intensity of described adapter.
Figure 24 is the stereographic map of another embodiment of the present invention.As shown in figure 24, folder 182 is installed and is made one with adaptor body 180.Folder 182 is installed is comprised that one makes one with adaptor body 182 and perpendicular to the first 184 of the central shaft of port one 99.One second portion 186 extends through an opening 181 that is formed in the flange 183 of adapter walls 180.Described second portion is substantially perpendicular to first 184.As shown in figure 25, second portion 186 comprises a jut 120 of describing in conjunction with Figure 10 hereinbefore.Folder 182 is installed is made by a kind of resilient material, can be towards the adaptor body bending, and can get back to its original position in case pass the opening of a plate.
Figure 26 is the stereographic map of the another embodiment of described adapter.The difference of adapter 190 and aforementioned several embodiment is that each installs folder 192 is members independently, does not make one with described sleeve pipe clamper or adaptor body.The opening that folder 192 is positioned at adaptor body is installed.The end that folder 192 is installed comprises a jut 120 of describing hereinbefore.Though shown in the figure is ST-SC structure,, also can use with any structure described above folder 192 independently is installed.Folder 129 is installed can link to each other with adaptor body in many ways.At first, the inflexibility end that leaves jut 120 can be press-fit in the described adaptor body.Perhaps, each can be installed folder 129 and one set collar and be molded together, and after welding, hold them between the flange of two adaptor bodies.Another kind of version is to adopt the mechanical type breech lock or use a kind of cementing agent to press from both sides 129 and link to each other with described adaptor body installing.
Though being depicted as, the present invention comprises duplex adapters body and duplexing grip sleeve,, should be understood that, that benefit of the present invention obtains by using each single worker's adaptor body and single worker's grip sleeve.That is to say that each installs folder can make one with single worker's grip sleeve, single worker's adaptor body, or each individual member in single worker's adapter.Therefore, not will be understood that the present invention only limits to duplexing embodiment.
