The process adopting single-core fiber assembly of the present invention to load and unload optical fiber roughly comprises: single core optical module is welded as a whole on optical communication equipment, first pulls up activity male 2 from single core optical module female seat 1 when carrying out Fiber connection; Then the fiber entrance hole 241 of plastic optical fiber from activity male 2 is inserted, through active lock gripping members 27, enter optical fiber entrance hole 224, until concordant with the front end of butt junction 22, now by tightening fastener parts 28, make active lock gripping members 27 and optical fiber lock fasten positive stop lug boss 211 and fasten and lock optical fiber; Then the activity male 2 with plastic optical fiber is inserted the docking chamber 14 of fixing female seat, until fixing female seat 1 is inserted in the butt junction 22 of activity male 2 completely, now Part I 221 is fitted completely with the Part I 141 docking chamber 14, at this moment buckle 25 can correspondingly with buckle shoulder 15 fasten to together, and make the two combine, thus the plastic optical fiber (scheming not shown) be installed in this activity male 2 can connect with the photoelectric chip be installed in fixing female seat 1 well.When needs exit plastic optical fiber, only need screwed tightening firmware 28, unclamp active lock gripping members 27, can plastic optical fiber be taken out.
Embodiment two:
The present embodiment is movable twin-core optical communication module, and its outward appearance and assembling schematic diagram are as shown in Figure 7.
As shown in Figure 7, the present embodiment is merged together by the identical structural member of two in embodiment one, twin-core transmitting-receiving subassembly clamp 81 is merged into by the clamp in embodiment one 16 two, female seat in embodiment one 1 two is merged into twin-core transmitting-receiving subassembly female seat 82, two activity males 21 in embodiment one merge twin-core transmitting-receiving subassembly activity male 83, and two in embodiment one little door-plates 24 merge the little door-plate 84 of twin-core transmitting-receiving subassembly.
With embodiment one unlike, the present embodiment can accommodate two photoelectric chips (scheming not shown), corresponding, can load and unload twin-core fiber.And for the locking loose unloading of single-core fiber, its channel interior structure is just the same.
The process of the movable twin-core light transmitting-receiving subassembly handling optical fiber of the present embodiment is adopted roughly to comprise:
Movable twin-core optical module as a whole (outward appearance is as Fig. 7) is welded on optical communication equipment, first pulls up activity male 83 from fixing female seat 82 when carrying out Fiber connection; Then the fiber entrance hole 241 of a plastic optical fiber from activity male 83 is inserted, through active lock gripping members 27, enter inner via hole 224, until concordant with the front end of butt junction 22, now by tightening fastener parts 86, make active lock gripping members 85 and optical fiber lock fasten spacing small boss 211 and fasten and lock optical fiber; The second core fibre is locked with method.
Then the activity male 83 with plastic optical fiber is inserted fixing female seat 82, at this moment buckle 831 can correspondingly with buckle shoulder 821 fasten to together, and make the two combine, thus the plastic optical fiber (scheming not shown) be installed in this activity male 83 can connect with the photoelectric chip be installed in fixing female seat 82 (scheming not shown) well.When needs exit plastic optical fiber, only need screwed tightening firmware 86, unclamp active lock gripping members 85, can plastic optical fiber be taken out.
Embodiment three:
The present embodiment is single-core fiber splicing connector, and its outward appearance and assembling schematic diagram are as shown in Figure 8.
With two kinds of embodiments above unlike, the present embodiment single-core fiber splicing connector is by continuous for two fiber alignments.Therefore female seat body 90 only has docking chamber 91 and buckle shoulder 92.
The single-core fiber of the present embodiment is adopted to continue to connect the process of handling optical fiber roughly to comprise:
First activity male 2 is pulled up from female seat 90 one end of continuing; Then plastic optical fiber (scheming not shown) is inserted, until concordant with the front end of butt junction 22, now lock optical fiber by tightening fastener parts 96; Then the activity male 2 with plastic optical fiber is inserted the female seat 90 that continues, at this moment buckle 93 can correspondingly with buckle shoulder 91 fasten to together, and makes the two combine.Same treatment other end optical fiber locking docking.Thus the docking completing two optical fiber continues.
Compared with prior art, optical fiber lock locking structure of the present invention, multiple optical communication modular structure or fibre junction connector construction can be built, make to adopt these optical communication modules of the present invention or connector the same with the connection procedure of cable and equipment in Fiber connection process, extremely applicable industrial environment equipment also meets business, home environment equipment.
Foregoing is only preferred embodiment of the present invention, and not for limiting embodiment of the present invention, the optical communication module that those of ordinary skill in the art's central scope according to the present invention designs or the joints of optical fibre should be considered as scope.
