Detailed Description
Current fiber optic adapters generally include a first mating portion and a second mating portion. The first adapter part is arranged outside the optical module box, or most of the first adapter part is arranged outside the optical module box, and the second adapter part is arranged inside the optical module box, namely, the optical fiber extending out of the first adapter part is used for connecting an external optical path, and the optical fiber extending out of the second adapter part is used for connecting an optical path in the optical module box. In the prior art, the first adapting part and the second adapting part are fixed together through ultrasonic welding, and the assembly process needs to be carried out by means of ultrasonic welding equipment, so that the cost is high.
In addition, in the conventional optical fiber connecting device, when two or more optical fibers are needed, only a plurality of optical fiber adapters can be combined for use, so that a certain gap, namely, the frame distance of the groove, needs to be reserved between the plurality of optical fiber adapters in order to be matched with the optical module box, the size of the whole optical fiber connecting device is increased, and the requirement of compact installation of the optical fiber adapters is not met.
In view of the above problems, embodiments of the present invention provide a fiber optic adapter assembly, which includes at least one first adapter portion, at least one second adapter portion, and a fixing portion;
the first adapting part is used for adapting the optical fiber connector at one end of the optical fiber adapter component;

the fixing part comprises a first preset structure which simultaneously limits the axial and vertical positions of the first adapting part and the second adapting part;
the first adaptation portion with the second adaptation portion all is provided with and presets the structure complex second with first presetting.
According to the optical fiber adapter assembly provided by the embodiment of the invention, the first adapting part and the second adapting part are fixed together through the fixing part, the axial and vertical positions of the first adapting part and the second adapting part are limited, the first adapting part and the second adapting part are prevented from being fixed through welding, the process is simplified, the cost is reduced, and the optical fiber adapter assembly is formed by the plurality of first adapting parts and the plurality of second adapting parts through the fixing part, so that the interval between two or more optical fiber adapters in matched use is reduced, the mounting area of an optical module box panel is effectively reduced, and the compact mounting requirement of the optical fiber adapters is met.
In other embodiments of the present invention, the fixing portion includes a first connection plate provided with a first preset structure, the first connection plate being located above and/or below the first fitting portion and the second fitting portion; the first preset structure is a connecting lug arranged on the first connecting plate, and the connecting lug comprises at least two lugs extending downwards or upwards; the second preset structure is a splicing groove matched with the connecting lug, and the first adapting part and the second adapting part are respectively provided with at least one splicing groove on the upper surface and/or the lower surface. The connecting lug and the splicing groove are of a concave-convex combined structure, have the characteristics of simplicity in implementation, reliability in fixation and convenience in disassembly, do not damage the first adapting part and the second adapting part, and are better implementation modes. Here, the first connecting plate may be provided only above or below the first fitting portion and the second fitting portion, or may be provided both above and below. It can be understood that: the first preset structure is a groove, and the second preset structure is a bump, so that the fixing purpose can be achieved.
In other embodiments of the present invention, the splice groove has an L-shaped cross section in the axial direction of the first adapting portion, and the coupling protrusion is adapted to the shape of the splice groove. The L-shape is a shape that can restrict the axial and vertical positions of the second fitting portion at the same time, and is a more preferable embodiment because the processing is also simple. It is understood that a dovetail shape, a V shape, or the like may be used.
In other embodiments of the present invention, the depth of the splicing groove is greater than a preset value, after the first connecting plate is connected to the first adapting portion and the second adapting portion, the top end of the first connecting plate is lower than or equal to the top ends of the first adapting portion and the second adapting portion. Such a fiber optic adapter assembly is lower in height, small in size, and suitable for compact installation of fiber optic adapters, and is a preferred embodiment. The preset value here may be set according to the thickness of the first connection plate. The term "higher" means that the top end of the first connecting plate is flush with the top ends of the first fitting part and the second fitting part.
In other embodiments of the present invention, the fixing portion includes two first connecting plates respectively located above and below the first fitting portion and the second fitting portion; the fixing part also comprises a second connecting plate which is connected with the two first connecting plates, and the second connecting plates are respectively arranged at two sides of the first adapting part and the second adapting part; the second connecting plate is fixed with the first connecting plate through a buckle structure. The buckle structure is convenient to mount or dismount and is a better implementation mode.
Further, the second connecting plate is used for connecting the two first connecting plates, and meanwhile, the transverse positions of the first adapting parts and the second adapting parts are limited, so that the axial direction, the vertical direction and the transverse direction of the first adapting parts are limited, the optical fiber connector assembly is more stable, and the optical fiber connector assembly is a better implementation mode.
In other embodiments of the present invention, the first connecting plate is provided with a cut-off marking line in a length direction thereof, the cut-off marking line is perpendicular to the length direction of the first connecting plate, and a distance between the cut-off marking line and an end of the first connecting plate or a distance between adjacent cut-off marking lines is adapted to a width of the first adapting portion. Like this, the optical fiber adapter quantity that can make up as required cuts first connecting plate, and the processing cost is low, and convenient to use, flexibility are better implementation mode.

the elastic bulge is used for adapting to the mounting hole of the light module box;
the combination groove is used for accommodating the elastic bulge when more than two first adapting parts are combined.
Thus, a plurality of first adapter portions can be used in combination, and compared with a single adapter portion, the size of the optical module box is saved (because each optical fiber adapter needs to be grooved in the optical module box, a plurality of frames are needed for forming a plurality of small grooves, and a frame can be saved for forming a large groove), which is a better implementation mode.
In other embodiments of the present invention, the first fitting part includes: the first elastic bulge and the first combination groove are arranged on the outer side wall of one side of the first elastic bulge and the first combination groove, and the second elastic bulge and the second combination groove are arranged on the outer side wall of the other side of the first elastic bulge and the second combination groove;
the first elastic bulge and the second elastic bulge are both used for adapting to the mounting hole of the light module box;
the first combination groove is used for accommodating the second elastic bulge when more than two first adapting parts are combined;
the second combination groove is used for accommodating the first elastic bulge when more than two first adapting parts are combined;
the positions of the first combination groove and the second elastic bulge are axisymmetrical in the axial direction of the first adapting part; the second combination groove and the first elastic bulge are axially symmetrical in the axis direction of the first adapting part. The axial symmetry here is limited to position only and the shape is not symmetrical.
Thus, each first adapting part is the same, so that the first adapting parts are more convenient to combine and are better embodiments. In order to ensure that the elastic protrusions are disposed on both sides of the assembled optical fiber adapter, the first adapter parts of the two types must be designed, and the arrangement of the elastic protrusions and the assembling grooves on the left and right sides of each first adapter part is different. In the present embodiment, each first fitting portion is the same, but the first fitting portion itself has different sides.
In other embodiments of the present invention, the elastic protrusion includes an elastic arm extending substantially in an axial direction, and the combination recess includes a hook plate hooking the elastic arm therein. Thus, in addition to restricting the position where the two first fitting portions are combined, the two first fitting portions can be prevented from being disengaged in the combining direction, which is a more preferable embodiment. Here, the elastic protrusions also include first and second elastic protrusions, and the combining grooves also include first and second combining grooves; the substrate extends along the axial direction, which means that the substrate may deviate by 5-10 degrees in the axial direction due to the reason of convenient assembly or processing error, but the axial extending direction is basically maintained.
The embodiment of the invention also provides an optical fiber connecting device, which comprises an optical fiber adapter and at least two optical fiber connectors respectively connected to two ends of the optical fiber adapter; the fiber optic adapter is any of the fiber optic adapter assemblies described above.
