Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connection, in particular to a flange ferrule sleeve. Background Art

[0002] In the traditional OSA (optical and electrical conversion) optical fiber transceiver module, the ferrule sleeve assembly does not have a mounting positioning plate. It can only be connected to the SC / LC type optical fiber activity connector when it is stuck in the module. If the ferrule sleeve assembly is to be docked with the SC type optical fiber activity connector (fast plug and unplug), a standard double-headed SC / PC flange and a standard SC / PC connector need to be added in the traditional structure.

[0003] One more jumper and adapter lead to an increase in the number of optical path transfers, which will increase the optical path loss and cost. In the case of increased optical path loss and cost, the market competitiveness of this adapter will be weakened. Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a flange ferrule sleeve to solve the problem that one more jumper and adapter lead to an increase in the number of optical path transfers, which will increase the optical path loss and cost.

[0005] To achieve the above object, the basic scheme of the utility model is as follows: A flange ferrule sleeve includes a flange assembly detachably installed between the ferrule sleeve assembly and the connector assembly. The flange assembly includes:

[0006] A first flange, which is fixedly connected to the ferrule sleeve assembly;

[0007] A second flange, which is fixedly connected to the connector assembly;

[0008] A connecting member detachably connecting the first flange and the second flange.

[0009] The technical principle of the utility model is: The first flange and the ferrule sleeve assembly form an integral structure, the second flange can form an integral structure with the connector assembly. The first flange and the second flange provide a stable connection structure for the connection between the ferrule sleeve assembly and the connector assembly. The connecting member can make the first flange and the second flange stably and tightly connected; at the same time, after the connector assembly is matched with the second flange, the connector assembly can be more stably and accurately matched with the ferrule sleeve assembly, reducing the loss of the optical link caused between the connector assembly and the ferrule sleeve assembly.

[0010] Further, the ferrule sleeve assembly includes:

[0011] A ferrule for inserting an optical fiber;

[0012] A closed-end sleeve coaxially and fixedly installed on the outer wall of one end of the ferrule;

[0013] A core fixing member is coaxially sleeved and fixedly installed at the connection between the closed sleeve and the ferrule. A ring-shaped first flange is fixedly arranged at the middle part of the core fixing member.

[0014] An interface member is coaxially and fixedly sleeved outside the core fixing member and the closed sleeve. The inner wall of the middle part of the interface member abuts against one end of the closed sleeve away from the ferrule, and one end of the interface member away from the closed sleeve abuts against one side of the first flange close to the connector assembly.

[0015] A clamping part connected to the connector assembly;

[0016] A first through hole for the closed sleeve, the core fixing member and the interface member to pass through is provided at the middle part of the first flange. A second flange coaxially arranged at the first through hole of the first flange abuts against one side of the first flange close to the connector assembly. The second flange wraps outside the interface member, and the clamping part is fixedly installed on one side of the first flange close to the second flange.

[0017] Through the above settings, the ferrule, the closed sleeve, the core fixing member and the interface member are precisely matched, so that finally the first flange and the second flange can also be precisely installed on the ferrule. The clamping part can be precisely clamped and matched with the connector assembly, so that the connector assembly is precisely matched with the ferrule under the fixation of the first flange and the second flange, and the optical energy output by the transmitting optical fiber can be coupled into the receiving optical fiber to the maximum extent.

[0018] Further, the connector assembly includes:

[0019] An SC / PC connector, and the SC / PC connector is pluggably connected to the clamping part;

[0020] A dust cap is sleeved and fixed on the end of the SC / PC connector;

[0021] A second through hole for the clamping part, the closed sleeve and the interface member to pass through is provided on the second flange. A housing for clamping the outer wall of the dust cap is provided on one side of the second flange away from the first flange.

[0022] Through the above settings, the housing can further cooperate with the dust cap to realize the stable installation of the SC / PC connector and the second flange, so that the SC / PC connector pluggably installed on the clamping part can be more precisely and stably matched with the ferrule.

[0023] Further, the clamping part includes a plurality of tenons, and a third flange that can pass through the dust cap and abut against the outer wall of the SC / PC connector is provided at the end of the tenon.

[0024] With the above settings, after the third flange on the tenon abuts against the side wall of the SC / PC connector, rapid elastic docking between the tenon and the SC / PC connector can be achieved, making the insertion and extraction of the SC / PC connector more convenient and simpler.

[0025] Furthermore, a fourth flange that can abut against the third flange is provided on the outer wall of the SC / PC connector.

[0026] With the above settings, after the fourth flange and the third flange cooperate, the fitting and installation of the SC / PC connector and the ferrule are more stable, making the connection performance between optical fibers more stable and the quality more reliable.

[0027] Furthermore, the clamping portion further includes a connecting plate. One ends of several tenon connecting plates away from the third flange are fixedly connected to the connecting plate. A third through hole for the closed sleeve and the interface member to pass through is provided at the center of the connecting plate. The connecting plate is located within the second through hole and is fixedly connected to the first flange or the interface member.

[0028] With the above settings, the connecting plate can make the cooperation and installation between the tenon and the first flange or the interface member more stable, making the performance of the tenon more stable during the insertion and extraction process.

[0029] Furthermore, a limiting chute is provided at the end of the housing away from the second flange and penetrating through the end of the housing. A limiting slider that can be embedded in the limiting chute is fixedly provided on the outer wall of the dust cap.

[0030] With the above settings, when the SC / PC connector is pushed and inserted into the second flange and the housing, the limiting slider on the outer wall of the dust cap is embedded into the limiting chute of the housing to guide the insertion of the SC / PC connector at this time, making the insertion of the SC / PC connector more convenient and easy for the installation staff to operate.

[0031] Furthermore, it further includes a spring piece. One end of the spring piece is connected to the outer wall of the housing, and the other end of the spring piece is opposite to the outer wall of the housing.

[0032] With the above settings, when inserting the SC / PC connector, the hand can hold the spring piece, which is more convenient for applying force to the housing, making it easier to insert the SC / PC connector into the housing and the second flange.

[0033] Furthermore, several first positioning holes penetrate through the edge of the first flange, and several second positioning holes that can coincide with the first positioning holes penetrate through the edge of the second flange. The connecting member is installed at the first positioning holes and the second positioning holes.

[0034] With the above settings, the connecting member can stably and tightly connect the first flange and the second flange through the first positioning holes and the second positioning holes, making the cooperation between the first flange and the second flange precise.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0043] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0044] This embodiment is basically as Figures 1 - 5 shown. An embodiment of the present utility model provides a flange ferrule, which includes a flange assembly detachably installed between a ferrule 10 sleeve assembly and an SC / PC connector 20 assembly. The flange assembly includes a first flange 30, a second flange 40, an elastic piece 401, and a connecting piece detachably connecting the first flange 30 and the second flange 40. Both the first flange 30 and the second flange 40 are metal flanges.

[0045] As Figures 1 - 5As shown in the figure, the ferrule 10 set of components includes a ferrule 10 for inserting an optical fiber, a closed sleeve 101, a ferrule fixing member 102, an interface member 104, and a clamping portion connected to the SC / PC connector 20 set of components. The ferrule 10 is a ceramic ferrule 10, and the grinding degree of the ceramic ferrule 10 is 8°. The closed sleeve 101 is a closed ceramic sleeve, and the closed sleeve 101 is coaxially and fixedly installed on the outer wall of one end of the ferrule 10. The ferrule fixing member 102 is coaxially sleeved and fixedly installed at the connection between the closed sleeve 101 and the ferrule 10. A ring-shaped first flange 103 is integrally formed at the middle of the ferrule fixing member 102. The interface member 104 is coaxially and fixedly sleeved outside the ferrule fixing member 102 and the closed sleeve 101, and the inner wall of the middle of the interface member 104 abuts against the end of the closed sleeve 101 away from the ferrule 10. One end of the interface member 104 away from the closed sleeve 101 abuts against the side of the first flange 103 close to the SC / PC connector 20 set of components. A first through hole for the closed sleeve 101, the ferrule fixing member 102, and the interface member 104 to pass through is provided at the middle of the first flange 30. A second flange 301 that abuts against the side of the first flange 103 close to the SC / PC connector 20 set of components is integrally formed coaxially at the first through hole of the first flange 30, and the second flange 301 wraps around the outside of the interface member 104.

[0046] At the same time, as Figures 1 - 5 shown, the SC / PC connector 20 set of components includes an SC / PC connector 20 and a dust cap 201. The dust cap 201 is sleeved and fixed on the left end of the SC / PC connector 20. A second through hole for the clamping portion, the closed sleeve 101, and the interface member 104 to pass through is provided on the second flange 40. An outer shell 403 that is clamped to the outer wall of the dust cap 201 is integrally formed on the side of the second flange 40 away from the first flange 30. A limiting chute 404 is provided at the end of the outer shell 403 away from the second flange 40 and penetrating through the end of the outer shell 403. The cross-sectional contour of the limiting chute 404 is in the shape of a "U". A limiting slider 202 that can be embedded in the limiting chute 404 is fixedly provided on the outer wall of the dust cap 201. When the limiting slider 202 is located in the limiting chute 404, the dust cap 201 is clamped to the outer shell 403 in place.

[0047] At the same time, as Figure 3 shown, the clamping portion includes two tenons 105 and a connecting plate 107. A third flange 106 that can pass through the dust cap 201 and abut against the outer wall of the SC / PC connector 20 is integrally formed at the end of the tenon 105. A fourth flange 203 that can abut against the third flange 106 is provided on the outer wall of the SC / PC connector 20. Both ends of the two tenons 105 away from the third flange 106 are integrally formed with the connecting plate 107. A third through hole for the closed sleeve 101 and the interface member 104 to pass through is provided at the center of the connecting plate 107. The connecting plate 107 is located in the second through hole, and the connecting plate 107 is welded to the right side of the first flange 30.

[0048] As Figures 1 - 3 shown, the number of the elastic pieces 401 is two, and the two elastic pieces 401 are located on opposite sides of the outer shell 403. A connecting piece 402 that wraps around the outer wall of the outer shell 403 is integrally formed between the two elastic pieces 401. The connecting piece 402 is snap-fitted and installed on the outer wall of the outer shell 403; one end of the elastic piece 401 is fixedly attached to the outer wall of the outer shell 403, the other end of the elastic piece 401 faces the outer wall of the outer shell 403, and the extending direction of the elastic piece 401 is consistent with the axial direction of the outer shell 403.

[0049] Meanwhile, as Figures 1 - 3 shown, both the first flange 30 and the second flange 40 are rectangular. A first positioning hole 302 penetrates through the edges at both ends of the first flange 30, and a second positioning hole 405 that can coincide with the first positioning hole 302 penetrates through the edges at both ends of the second flange 40. The connecting piece is installed at the first positioning hole 302 and the second positioning hole 405, and the connecting piece is a rivet 50.

[0050] When the flange ferrule in this embodiment is in use, the core fixing member 102 is press-fitted onto the ferrule 10. At this time, the ferrule 10 is set with a 108° direction facing outward, and the ferrule 10 and the core fixing member 102 are press-fitted in place; then the closed-end sleeve 101 is press-fitted onto the right end of the ferrule 10, and the left end of the closed-end sleeve 101 is embedded into the right end of the core fixing member 102, and the closed-end sleeve 101 is press-fitted in place.

[0051] Then, the assembly of the flange assembly is carried out. The closed-end sleeve 101, the core fixing member 102, and the interface member 104 pass through the first through-hole of the first flange 30, and the second flange 301 of the first flange 30 abuts against the first flange 103 of the core fixing member 102; the clamping portion, the closed-end sleeve 101, and the interface member 104 pass through the second through-hole of the second flange 40, and the second positioning hole 405 on the second flange 40 coincides with the first positioning hole 302 of the first flange 30. At this time, the first positioning hole 302 and the second positioning hole 405 of the first flange 30 and the second flange 40 are riveted and fixed by using the rivet 50, so as to realize the riveting and fixing of the first flange 30 and the second flange 40.

[0052] Then, connect the SC / PC connector 20 and the dust cap 201 to the second flange 40 and the housing 403. Push the SC / PC connector 20 into the second flange 40 and the housing 403. The limiting slider 202 on the outer wall of the dust cap 201 is inserted into the limiting chute 404 of the housing 403 to guide the insertion of the SC / PC connector 20 at this time. When the side wall of the end of the SC / PC connector 20 moves to the tenon 105, the third flange 106 at the end of the tenon 105 passes through the dust cap 201 and abuts against the fourth flange 203 on the SC / PC connector 20, realizing the accurate positioning and insertion of the SC / PC connector 20. During the whole process, the double-headed SC / PC flange and a standard SC / PC connector 20 are omitted, effectively improving the space utilization rate and saving costs.

[0053] When inserting the SC / PC connector 20, the SC / PC connector 20 can be more stably and quickly guided by the cooperation of the limiting slider 202 and the limiting chute 404 between the housing 403 and the dust cap 201 to the tenon 105 quickly. It is also convenient for the third flange 106 to abut and cooperate with the fourth flange 203, realizing the stable and quick insertion of the SC / PC connector 20, and facilitating the accurate cooperation of the SC / PC connector 20 to the closed sleeve 101. The four-way performance of the closed sleeve 101 is better than that of the traditional open ceramic ring, and can realize the high-precision docking of the SC / PC connector 20 and the ferrule 10.

[0054] At the same time, since the ferrule 10 is a ceramic ferrule 10, the closed sleeve 101 is a closed ceramic sleeve, and the first flange 30 and the second flange 40 are both metal flanges, the whole flange-ferrule sleeve has the characteristics of strong anti-corrosion performance and high reliability.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
