Description

Technical Field

[0001] This invention relates to the field of optoelectronic connectors, and more particularly to an "L"-shaped optoelectronic hybrid fiber optic active connector and its assembly method. Background Technology

[0002] To achieve fiber-to-the-home (FTTH) and fiber-to-every-room (FTNL) connectivity, the main gateway and secondary gateways must transmit both optical and electrical signals. Currently, some manufacturers are starting to produce connectors, but these are mostly prefabricated in the factory and then delivered to the site. The length of the fiber optic cable after cabling can affect usability and aesthetics; furthermore, they are primarily straight, requiring careful planning of the cable coiling radius, which also impacts the appearance of the coiled cable. Even slight bends can increase light loss. Summary of the Invention

[0003] The purpose of this invention is to address the technical problem that existing optoelectronic connectors are all straight, which wastes optical cable materials and affects optical loss, by proposing an "L"-shaped optoelectronic hybrid fiber optic active connector and its assembly method.

[0004] An "L"-shaped optoelectronic hybrid fiber optic active connector includes an optoelectronic hybrid cable, a connector body, a ceramic ferrule, and an optoelectronic hybrid adapter, wherein the connector body is "L"-shaped.

[0005] Furthermore, an "L"-shaped optoelectronic hybrid fiber optic active connector is provided, wherein the front end of the connector body and the optoelectronic hybrid adapter are locked together, the optoelectronic hybrid adapter encloses a ceramic ferrule, and the optoelectronic hybrid cable is connected to the connector body.

[0006] Furthermore, an "L"-shaped optoelectronic hybrid fiber optic active connector is provided, wherein a ceramic ferrule is connected to the front end of the connector body, and an optoelectronic hybrid cable is connected to the lower right end of the connector body. The connector body includes a connector shell, a V-groove tail shank, a bare optical fiber, a V-groove, a tapered guide, a coated optical fiber, a loose-fitting tail shank, barbed teeth, and a spring.

[0007] Furthermore, in an "L"-shaped optoelectronic hybrid fiber optic active connector, the other end of the ceramic ferrule is connected to the front end of the V-groove, the tail of the V-groove is pressed and fixed to the ceramic ferrule, the other end of the V-groove is provided with a tapered guide hole, and the end of the V-groove is tightly connected to a spring.

[0008] Furthermore, an "L"-shaped optoelectronic hybrid fiber optic active connector is provided with a loose component tail sleeve at the lower right end of the connector body. The tail sleeve has barbed teeth at its end. When the optoelectronic hybrid cable is inserted into the tail sleeve, the barbed teeth can firmly lock the optoelectronic hybrid cable. The outer shell of the tail sleeve is set with a rough surface.

[0009] Furthermore, an "L"-shaped optoelectronic hybrid fiber optic active connector, wherein the connector body shell includes a metal spring strip and a connector head stop, and the loose parts include a tail sleeve opening knob and a tail sleeve buckle.

[0010] Furthermore, in an "L"-shaped optoelectronic hybrid fiber optic active connector, two metal spring strips are disposed on the left end of the connector body shell, a connector head stop is used to measure the insertion length when inserting the optoelectronic adapter, a tail sleeve opening knob controls the opening of the loose component tail sleeve, and a tail sleeve buckle controls the locking of the loose component tail sleeve.

[0011] Furthermore, an "L"-shaped optoelectronic hybrid fiber optic active connector is provided, wherein the optoelectronic hybrid adapter includes metal guide strips and fixing clips. The two metal guide strips are used to guide electrical signals, and the upper end of the optoelectronic hybrid adapter is provided with two fixing clips to fix the optoelectronic hybrid adapter in the FTTR optical modem or information panel.

[0012] An assembly method for an "L"-shaped optoelectronic hybrid fiber optic active connector includes the following steps:

[0013] S1. Strip 60mm of the fiber optic hybrid cable, remove the excess fiber optic sheath with a cable stripper or other tools, and strip the last 30mm of the coated fiber optic cable to bare fiber optic cable with fiber stripping pliers and clean it with alcohol swabs.

[0014] S2. Crimp the tail sleeve buckle. Open the right half of the loose tail sleeve, insert the optical fiber into the main body, guide it through the conical guide into the V-groove and successfully pass it out of the ceramic ferrule. Connect the two power sources in the optical-electric hybrid cable to the root crimping point of the metal spring strip according to their polarity and crimp them.

[0015] S3. Press the tail sleeve of the loose part back to the tail end. The barbed teeth on the tail sleeve of the loose part "bite" the sheath of the optical and electrical hybrid cable. Press it tightly to ensure that the snap-on tail sleeve buckle is locked.

[0016] S4. Use a fiber optic cleaver to cut off the bare fiber that is protruding from the ceramic ferrule. Place the connector body into a fiber optic splicer to splice the end face of the ceramic ferrule. After splicing, use a fiber optic end face inspection instrument to inspect the end face. If it passes the inspection, put on a dust cap and wait for use.

[0017] S5. Insert the fixing clips of the photoelectric hybrid adapter into the reserved mounting holes of the information panel or FTTR optical modem. The diameter of the mounting hole matches the fixing clip. After insertion, crimp the two metal guide strips to the power cord on the information panel or FTTR optical modem.

[0018] S6. Remove the dust cap from the connector body and insert it into the optoelectronic hybrid adapter to complete the assembly, and the light and electricity are connected simultaneously.

By designing an "L"-shaped main body, the optical cable does not need to be exposed during use, further improving the aesthetics of the site. Corresponding fixing buckles and metal guide strips are designed on the injection-molded shell of the optoelectronic adapter, so that both optical and electrical signals of the optoelectronic hybrid connector can be transmitted through the connector adapter.

Detailed Implementation

[0025] The present invention will be further described below, but the scope of protection of the present invention is not limited to the following description.

[0026] like Figure 1 As shown, an "L"-shaped optoelectronic hybrid fiber optic movable connector includes an optoelectronic hybrid cable 1, a connector body 2, a ceramic ferrule 3, and an optoelectronic hybrid adapter 4. The connector body 2 is "L"-shaped. The optoelectronic hybrid cable 1 includes an outer sheath, and the sheath contains at least one optical fiber and two copper cables. After being stripped, the cable is inserted into the connector body 2, and then the "L"-shaped optoelectronic hybrid fiber optic movable connector is realized through the matching optoelectronic hybrid adapter 4.

[0027] like Figure 2 As shown, the front end of the connector body 2 and the optoelectronic hybrid adapter 4 are locked together. The optoelectronic hybrid adapter 4 encloses the ceramic ferrule 3, and the optoelectronic hybrid cable 1 is connected to the connector body 2.

[0028] The front end of the connector body 2 is connected to the ceramic ferrule 3, and the lower right end of the connector body 2 is connected to the optical-electric hybrid cable 1. The connector body 2 includes a connector shell 5, a V-groove tail stalk 6, a bare optical fiber 7, a V-groove 8, a tapered guide 9, a coated optical fiber 10, a loose component tail stalk 11, a barbed tooth 12, and a spring 14.

[0029] The other end of the ceramic insert 3 is connected to the front end of the V-groove 8. The tail shank 6 of the V-groove is pressed and fixed to the ceramic insert 3. The other end of the V-groove 8 is provided with a tapered guide hole 9. The end of the V-groove 8 is tightly connected to the spring 14.

[0030] The connector body 2 has a loose component tail sleeve 11 at the lower right end. The end of the loose component tail sleeve 11 is provided with barbed teeth 12. When the optoelectronic hybrid cable 1 is inserted into the loose component tail sleeve, the barbed teeth 12 can firmly lock the optoelectronic hybrid cable 1. The outer shell of the loose component tail sleeve 11 is set with a rough surface 13.

[0031] Bare fiber 7 is a G.657A2 or G.657B3 type fiber with good bending resistance, or a fiber with even better bending performance.

[0032] As attached Figure 3 As shown, the connector body shell 5 includes a metal spring strip 15 and a connector stop 16, and the loose component tail 11 includes a tail opening knob 17 and a tail buckle 18.

[0033] Two metal spring strips 15 are set on the left end of the connector body shell, the connector stop 16 is used to measure the insertion length when the optoelectronic adapter 4 is inserted, the tail sleeve opening knob 17 controls the opening of the loose part tail 11, and the tail sleeve buckle 18 controls the locking of the loose part tail 11.

[0034] As attached Figure 4 As shown, the optoelectronic hybrid adapter 4 includes metal guide strips 19 and fixing clips 20. The two metal guide strips 19 are used to guide electrical signals. The upper end of the optoelectronic hybrid adapter 4 is provided with two fixing clips 20 to fix the optoelectronic hybrid adapter in the FTTR optical modem or information panel.

[0035] In summary, the "L"-shaped hybrid optical fiber connector is an improvement on the existing SC structure. It meets the requirements for connecting hybrid optical cables, enabling accurate on-site installation. Furthermore, the "L"-shaped main body design fits better with optical modems or information panels, resulting in a more aesthetically pleasing on-site installation compared to prefabricated hybrid optical cables. Specifically, a tapered guide 9 is added to the middle of the components in the hybrid connector, allowing the stripped coated optical fiber 10 to be inserted along the "L" shape. The bare optical fiber 7 is then precisely guided into the standard ceramic ferrule 3 via a V-groove 8. The metal spring strip 15 connects to the copper cable in the optical cable, enabling the hybrid connector to transmit both optical and optical signals.

[0036] An assembly method for an "L"-shaped optoelectronic hybrid fiber optic active connector includes the following steps:

[0037] S1. Strip 60mm of the optical-electric hybrid cable 1, remove the excess optical cable sheath with a cable stripper or other tools, and strip the end 30mm of the coated optical fiber 10 into bare optical fiber with optical fiber stripping pliers (7) and clean it with alcohol cotton.

[0038] S2. Crimp the tail sleeve buckle 18, open the right half of the loose tail sleeve 11, insert the optical fiber into the main body, enter the V-groove 8 through the conical guide 9 and successfully pass through the ceramic ferrule 3, connect the two power sources in the optoelectronic hybrid cable 1 to the root crimping point of the metal spring strip 15 according to their polarity and crimp them.

[0039] S3. Press the tail sleeve 11 back to the tail end. The barbed teeth 12 on the tail sleeve 11 "bite" the sheath of the optical-electric hybrid cable 1 and press it tightly to ensure that the crimping tail sleeve buckle 18 is locked.

[0040] S4. Use a fiber optic cleaver to cut off the bare fiber 7 that protrudes from the ceramic ferrule 3. Place the connector body 2 into the fiber optic splicing machine to splice the fiber optic end face of the ceramic ferrule 3. After splicing, use a fiber optic end face detector to inspect the end face. If it passes the inspection, put on a dust cap and wait for use.

[0041] S5 and the fixing buckle 20 of the photoelectric hybrid adapter 4 are respectively inserted into the reserved mounting holes of the information panel or FTTR optical modem. The diameter of the mounting hole matches the fixing buckle 20. After insertion, the two metal guide strips 19 are crimped and connected to the power cord on the information panel or FTTR optical modem.

[0042] S6. Remove the dust cap from connector body 2 and insert it into optoelectronic hybrid adapter 4 to complete the assembly, and light and electricity are connected simultaneously.

[0043] In some embodiments, the optoelectronic hybrid connector further includes a crimping ring and a stop, both of which are located within the “L”-shaped body and fitted onto the handle ceramic ferrule 3. The single optical fiber passes through the handle ceramic ferrule 3, and the sheath of the single optical fiber carried by the stop is crimped into the crimping ring.

[0044] In some embodiments, a spring 14 is provided at the end of the V-groove 8, the ceramic ferrule 3 and the V-groove 8 are pressed together and fixed in the "L"-shaped body by the spring 14, and the central hole of the ceramic ferrule 3 is hollow before the optical fiber is inserted.

[0045] In some embodiments, both the ceramic ferrule 3 with a handle and the adapter are equipped with matching dust caps.

[0046] In some embodiments, the connector adapter includes a housing injection molded part and an inner core injection molded part. The inner core injection molded part is fixedly disposed inside the housing injection molded part. The inner core injection molded part is "H" shaped. The two ends of the inner core injection molded part are provided with barbs. The inner sleeve and the housing are both provided with slots. The barbs at both ends of the inner core injection molded part are respectively adapted to the slots of the inner sleeve and the housing.

[0047] By pre-laying the fiber optic cable and then precisely cutting it to the actual length required for on-site installation, waste or construction difficulties caused by excessively long or short hybrid fiber optic cables are avoided. This also enhances the aesthetics of the construction site. The "L"-shaped design eliminates the need for excessive fiber optic cable coils, further improving the appearance of the construction site.

[0048] This solution utilizes an "L"-shaped hybrid optical fiber connector and assembly method. The "L" shape design allows the hybrid optical cable to make a "right-angle turn" when connecting to fiber optic information panels, FTTR master modems, and slave modems, eliminating the need for installation personnel to intentionally reserve fiber optic coil radius. Furthermore, the absence of coil radius requirements significantly reduces space requirements, enabling installation in confined spaces. Simultaneously, the ingenious combination of the hybrid optical cable, the "L"-shaped hybrid optical connector, and the optical adapter perfectly solves problems such as wasted optical cables and unsightly, cluttered cable arrangements on-site.
