It will also be understood that terms such as those defined in common dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted as having an idealized or overly formal meaning unless the present disclosure clearly so defines.

[0035] In a Fiber to the Room (FTTR) application, it is necessary to directly arrange a fiber optic connector (such as an SC fiber optic connector) connected with an optical fiber into a room so that devices in the room (such as a router, a computer, etc.) can directly access the optical network.

[0036] Due to the complex and diverse room environment, optical fibers often need to pass through some pipes (such as wall pipes) during wiring, that is, the "pipe threading" operation needs to be carried out.

[0037] In some related technologies, a traction rope can be pre-passed through the pipe, and then the traction rope on one side of the pipe is tied to the optical fiber connector. Then, the traction rope is pulled from the other side of the pipe to drive the optical fiber connector and the optical fiber it connects through the pipe to complete the pipe threading process.

[0038] However, there is no structure for connecting the traction rope on the conventional optical fiber connector, so the connection operation is troublesome; moreover, there are many uneven structures on the optical fiber connector, and these structures are prone to rubbing against other structures during pipe threading, which not only results in a large resistance but also easily damages the optical fiber connector.

[0039] First, with reference to Figures 1 to 12 , the embodiments of the present disclosure provide a pipe threading assembly.

[0040] With reference to Figure 6 , the pipe threading assembly of the embodiments of the present disclosure includes a pipe threading outer sleeve 1 and a positioning member 2. Before threading the optical fiber connector 3, with reference to Figure 7 , the pipe threading outer sleeve 1 can be sleeved outside the optical fiber connector 3 through the positioning member 2 for pipe threading operation; after the pipe threading is completed, the pipe threading assembly can be removed to expose the optical fiber connector 3, and then it is connected to the connector housing 4 to form an optical fiber connector for reference Figure 5 .

[0041] In some embodiments, the optical fiber connector 3 includes at least one of an SC optical fiber connector, an FC optical fiber connector, an LC optical fiber connector, and an ST optical fiber connector.

[0042] As a way of the embodiments of the present disclosure, the applicable optical fiber connector 3 of the pipe threading assembly of the embodiments of the present disclosure can be known forms such as an SC optical fiber connector, an FC optical fiber connector, an LC optical fiber connector, and an ST optical fiber connector.

[0043] With reference to Figures 6 to 12 , the pipe threading assembly of the embodiments of the present disclosure includes: a hollow pipe threading outer sleeve 1, which includes a main opening 12, a traction structure 13, and a first positioning groove 11; the main opening 12 is located at the first end of the pipe threading outer sleeve 1, the traction structure 13 is used to traction the pipe threading outer sleeve 1, the pipe threading outer sleeve 1 is used to be sleeved outside the optical fiber connector 3 through the main opening 12, and the optical fiber connector 3 includes a second positioning groove 31 for connecting with the connector housing 4; a positioning member 2, which includes a positioning pin 21; the positioning pin 21 is used to insert into the first positioning groove 11 and the second positioning groove 31 to relatively fix the pipe threading outer sleeve 1 and the optical fiber connector 3.

[0044] With reference to Figure 1 , Figure 2, The optical fiber connector 3 (taking the SC optical fiber connector as an example) is a connector connected to the optical fiber 9. During actual use, it can be sheathed with the connector housing 4 referring to Figure 3 , Figure 4 to form the optical fiber connector referring to Figure 5 . Among them, referring to Figure 2 , a second positioning groove 31 is provided in the optical fiber connector 3, and this second positioning groove 31 is a known structure for connecting the connector housing 4 and the optical fiber connector 3.

[0045] It should be understood that although the "SC optical fiber connector" is used as an example of the optical fiber connector 3 in some descriptions of the present disclosure, the pipe-passing assembly of the embodiments of the present disclosure is not limited to the SC optical fiber connector; for example, the pipe-passing assembly of the embodiments of the present disclosure can also be used for other types of optical fiber connectors 3 such as FC optical fiber connectors, LC optical fiber connectors, ST optical fiber connectors, etc. The specific structures of these optical fiber connectors 3, the forms of the second positioning grooves 31, the forms of the adapted connector housings 4, etc. are all different and known, and will not be described in detail here.

[0046] Referring to Figure 8 , Figure 9 , the pipe-passing assembly of the embodiments of the present disclosure includes a hollow pipe-passing outer sleeve 1. A first positioning groove 11 is provided on the pipe-passing outer sleeve 1, and the first end portion (also referred to as the rear end portion, Figure 8 , Figure 9 taking the right end as an example in

[0047] of the pipe-passing outer sleeve 1) has a main opening 12 communicating with the internal space, so that the optical fiber connector 3 can be inserted into the internal space of the pipe-passing outer sleeve 1 through this main opening 12, that is, the pipe-passing outer sleeve 1 is sleeved outside the optical fiber connector 3. Figure 8 , Figure 9 , the pipe-passing outer sleeve 1 also has a traction structure 13, and through this traction structure 13, a traction force can be applied to the pipe-passing outer sleeve 1 to pass it through the pipeline together.

[0048] For example, the traction structure 13 can refer to Figure 8 , Figure 9 , and is a traction hole provided at the second end portion (the end portion opposite to the first end portion, Figure 8 , Figure 9 taking the left end as an example in

[0049] of the pipe-passing outer sleeve 1. A traction rope or the like can be passed through this traction hole to realize the traction of the pipe-passing outer sleeve 1.

[0050] It should be understood that the specific position, form, etc. of the traction structure 13 are not limited to the above example of the traction hole, and it can also be a traction groove provided on the outer side wall of the pipe-passing outer sleeve 1, etc. Figure 10 , Figure 11, the pipe-passing component of the embodiments of the present disclosure further includes a positioning member 2 with a positioning pin 21. When the pipe-passing outer sleeve 1 is sleeved outside the optical fiber connector 3, referring to Figure 7 , the positioning pin 21 can pass through the first positioning groove 11 of the pipe-passing outer sleeve 1 and the second positioning groove 31 of the optical fiber connector 3 at the same time, so as to relatively fix the pipe-passing outer sleeve 1 and the optical fiber connector 3; after that, if the positioning pin 21 is pulled out, the pipe-passing outer sleeve 1 can be separated from the optical fiber connector 3.

[0051] It should be understood that the pipe-passing component of the embodiments of the present disclosure can be made of materials such as plastic and metal.

[0052] When using the pipe-passing component of the embodiments of the present disclosure to pass through a pipe, the pipe-passing outer sleeve 1 can be fixed outside the optical fiber connector 3 through the positioning member 2, and then the pipe-passing outer sleeve 1 is pulled by the traction structure 13 to make the optical fiber connector 3 (including the optical fiber 9 connected thereto) pass through the pipe. After that, the positioning member 2 is pulled out and the pipe-passing outer sleeve 1 can be removed; among them, since the optical fiber connector 3 is protected by the pipe-passing outer sleeve 1 during pipe-passing, the resistance is small and the optical fiber connector 3 will not be damaged; moreover, since the positioning pin 21 of the positioning member 2 is positioned through the original second positioning groove 31 (for connecting the joint housing 4) in the optical fiber connector 3, the embodiments of the present disclosure can ensure stable positioning (compared with methods such as snap connection) without changing the structure of the optical fiber connector 3, and at the same time make the disassembly and assembly operation of the pipe-passing outer sleeve 1 convenient (compared with methods such as threaded connection).

[0053] In some embodiments, referring to Figures 7 to 11 , the positioning member 2 further includes a support portion 24 connected to the positioning pin 21; a recessed portion 14 is provided on the outer side wall of the pipe-passing outer sleeve 1, and the first positioning groove 11 communicates with the recessed portion 14; the structures of the positioning member 2 and the pipe-passing outer sleeve 1 are configured such that when the positioning pin 21 is inserted into the first positioning groove 11 and the second positioning groove 31, at least a part of the support portion 24 is located in the recessed portion 14.

[0054] Referring to Figure 10 、 Figure 11 , the positioning member 2 further includes a support portion 24, and the positioning pin 21 is connected to the support portion 24; correspondingly, referring to Figure 8 、 Figure 9 , a recessed portion 14 is provided on the outer side wall of the pipe-passing outer sleeve 1, and the recessed portion 14 communicates with the first positioning groove 11, so that referring to Figure 7 , when the positioning member 2 is inserted, at least a part of the support portion 24 will be located in the recessed portion 14, and at the same time, the positioning pin 21 connected to the support portion 24 will be inserted into the first positioning groove 11 communicating with the recessed portion 14; the above method can better maintain the position stability of the positioning member 2.

[0055] In some embodiments, referring to Figure 7, the structural configuration of the positioning member 2 and the pipe-passing outer sleeve 1 is such that when the positioning pin 21 is inserted into the first positioning groove 11 and the second positioning groove 31, the outer surface of the supporting portion 24 is flush with the outer surface of the pipe-passing outer sleeve 1.

[0056] Referring to Figure 7 , as a way of the embodiment of the present disclosure, when at least a part of the supporting portion 24 is located in the recessed portion 14, the outer surface of the supporting portion 24 and the outer surface of the pipe-passing outer sleeve 1 can be exactly "aligned", for example, by making the thickness of the supporting portion 24 equal to the depth of the recessed portion 14. Therefore, the outer surfaces of the two form a plane or a smooth arc surface without obvious undulations as a whole, so that the outer surface of the pipe-passing assembly as a whole is smoother, further reducing the resistance during pipe passing.

[0057] In some embodiments, referring to Figure 7 , Figure 9 , Figure 10 , the structural configuration of the positioning member 2 and the pipe-passing outer sleeve 1 is such that when the positioning pin 21 is inserted into the first positioning groove 11 and the second positioning groove 31, one end of the supporting portion 24 extends beyond the first end of the pipe-passing outer sleeve 1.

[0058] Referring to Figure 7 , Figure 9 , Figure 10 , as a way of the embodiment of the present disclosure, the supporting portion 24 can be "long enough" so that when a part of the supporting portion 24 is located in the recessed portion 14, referring to Figure 7 , one end of the supporting portion 24 can "extend beyond" the first end of the pipe-passing outer sleeve 1, and the extended part can be called the "operating sub-portion 241", which can play a role similar to a "handle". As long as the operator grasps the operating sub-portion 241, the positioning member 2 can be pulled out, which is convenient for operation.

[0059] For example, the above-mentioned recessed portion 14 can also extend to the first end of the pipe-passing outer sleeve 1, so that the outer surface of the part of the supporting portion 24 located in the recessed portion 14 can be flush with the outer surface of the pipe-passing outer sleeve 1, and the part of the supporting portion 24 connected to the part located in the recessed portion 14 is the above-mentioned "operating sub-portion 241", and the outer surface of the operating sub-portion 241 is also flush with the outer surface of the part of the supporting portion 24 located in the recessed portion 14.

[0060] In some embodiments, referring to Figures 7 to 10, a clamping opening 16 communicating with the recessed portion 14 and extending to the first end is provided on the side wall of the pipe-passing outer sleeve 1; the supporting portion 24 includes a first portion, a second portion, and a third portion arranged in sequence, the positioning pin 21 is connected to the first portion, and a clamping protrusion 26 is connected to the second portion; the structural configuration of the positioning member 2 and the pipe-passing outer sleeve 1 is such that when the positioning pin 21 is inserted into the first positioning groove 11 and the second positioning groove 31, the first portion is located in the recessed portion 14, the second portion corresponds to the clamping opening 16 and the clamping protrusion 26 is clamped in the clamping opening 16, the third portion extends beyond the first end of the pipe-passing outer sleeve 1, and the outer surface of the supporting portion 24 is flush with the outer surface of the pipe-passing outer sleeve 1.

[0061] As a mode of the embodiment of the present disclosure, referring to Figure 7 , a clamping opening 16 is provided in the pipe-passing outer sleeve 1 on the side closer to the first end of the recessed portion 14, and the clamping opening 16 also communicates with the main opening 12; correspondingly, along the direction from the second end to the first end, the supporting portion 24 sequentially includes the following three portions.

[0062] The first portion is located in the recessed portion 14.

[0063] The second portion is located at a position corresponding to the clamping opening 16 and is connected with a clamping protrusion 26, so that the clamping protrusion 26 can be clamped in the clamping opening 16, and the positioning member 2 is better fixed on the pipe-passing outer sleeve 1; for example, along the circumferential direction of the pipe-passing outer sleeve 1, the size of the clamping protrusion 26 is "slightly larger" than the size of the clamping opening 16, so that the clamping protrusion 26 needs to be elastically deformed slightly to be inserted into the clamping opening 16 to achieve clamping.

[0064] The third portion is located outside the first end of the pipe-passing outer sleeve 1, that is, the above-mentioned "operating sub-portion 241".

[0065] At the same time, referring to Figure 6 , at this time, the outer surface of the supporting portion 24 (the outer surfaces of the above three portions) can also be flush with the outer surface of the pipe-passing outer sleeve 1, so as to better reduce the resistance during pipe passing.

[0066] In some embodiments, referring to Figures 7 to 10 , the positioning member 2 further includes a supporting portion 24 connected to the positioning pin 21, and a first clamping structure provided on the supporting portion 24; the pipe-passing outer sleeve 1 further includes a second clamping structure; the structural configuration of the positioning member 2 and the pipe-passing outer sleeve 1 is such that when the positioning pin 21 is inserted into the first positioning groove 11 and the second positioning groove 31, the first clamping structure is clamped with the second clamping structure.

[0067] Referring to Figures 7 to 10, as a mode of the embodiment of the present disclosure, the support portion 24 and the pipe-passing outer sleeve 1 may be respectively provided with a first engaging structure and a second engaging structure that can match each other. Thus, when the positioning member 2 is inserted, the first engaging structure can be engaged with the second engaging structure, so as to better fix the positioning member 2 on the pipe-passing outer sleeve 1.

[0068] It should be understood that the above first engaging structure and second engaging structure are not limited to the form of the engaging protrusion 26 and the engaging opening 16, and the pipe-passing outer sleeve 1 does not necessarily have the recessed portion 14; for example, it is also possible that the pipe-passing outer sleeve 1 has no recessed portion, so that the support portion 24 is directly provided "outside" the outer surface of the pipe-passing outer sleeve 1, and there is a bayonet as the first engaging structure inside the support portion 24, and a chuck as the second engaging structure on the outer surface of the pipe-passing outer sleeve 1, and the bayonet can be inserted into the bayonet.

[0069] In some embodiments, referring to Figures 8 to 11 , the positioning member 2 includes two positioning pins 21 arranged at intervals; the pipe-passing outer sleeve 1 includes two first positioning grooves 11 arranged at intervals; the optical fiber connector 3 includes two second positioning grooves 31 arranged at intervals.

[0070] Referring to Figures 8 to 11 , as a mode of the embodiment of the present disclosure, the number of the positioning pins 21, the first positioning grooves 11, and the second positioning grooves 31 may all be two, so as to more firmly fix the pipe-passing outer sleeve 1 relative to the optical fiber connector 3.

[0071] For example, referring to Figure 10 , Figure 11 , the two positioning pins 21 are respectively connected outside the two sides of the support portion 24 and extend towards the direction where the pipe-passing outer sleeve 1 is located; and referring to Figure 8 , Figure 9 , the two first positioning grooves 11 may be respectively arranged outside the two opposite sides of the recessed portion 14; referring to Figure 1 , Figure 2 , the two second positioning grooves 31 may be respectively located on the two opposite side surfaces of the optical fiber connector 3, or it can also be understood that the optical fiber connector 3 has a "waist" with relatively narrowed width at the positions of the two second positioning grooves 31.

[0072] Furthermore, the width of the above "waist" may be slightly narrower than the distance between the two positioning pins 21. Thus, when the two positioning pins 21 are inserted into the two second positioning grooves 31, they need to be elastically deformed slightly outwards, so as to generate an inward clamping stress, which plays a better fixing role.

[0073] It should be understood that the specific number, setting position, etc. of the positioning pins 21, the first positioning grooves 11, and the second positioning grooves 31 are not limited to the above examples.

[0074] In some embodiments, referring to Figure 10 ,Figure 12 The positioning pin 21 is used to insert into the first positioning groove 11 and the second positioning groove 31, and the end part for insertion is a pointed structure 211. Along the preset insertion direction, the outer diameter dimension of the pointed structure 211 gradually decreases; the insertion direction is the movement direction when the positioning pin 21 inserts into the first positioning groove 11 and the second positioning groove 31.

[0075] Refer to Figure 10 、 Figure 12 As a way of the embodiment of the present disclosure, one end of the positioning pin 21 for insertion can be a pointed structure 211, that is, the closer the positioning pin 21 is to the end part, the sharper it is (the smaller the outer diameter dimension), so that the resistance when the positioning pin 21 inserts into the first positioning groove 11 and the second positioning groove 31 can be reduced through the guidance of the pointed structure 211.

[0076] For example, when the two second positioning grooves 31 Figure 2 are located on two opposite sides of the optical fiber connector 3, the pointed structure 211 at the end of the positioning pin 21 can be in the form of the "inner inclined surface" Figure 12 referred to, so as to facilitate the "outward deformation" of the positioning pin 21 and insert it into the second positioning groove 31.

[0077] In some embodiments, Figure 8 、 Figure 9 the outer surface of the second end of the pipe sleeve 1 opposite to the first end is a convex arc surface.

[0078] Refer to Figure 8 、 Figure 9 As a way of the embodiment of the present disclosure, the second end (also called the front end) of the pipe sleeve 1 can have a convex arc surface on the outside, that is, the closer the pipe sleeve 1 is to the second end, the smaller the outer diameter dimension, and it is a smooth transition, so that the second end of the pipe sleeve 1 as a whole forms the shape of a "bullet head", which can further reduce the resistance during pipe threading.

[0079] In some embodiments, Figure 7 、 Figure 8 a plurality of anti-slip grooves 19 are provided on the outer side wall of the pipe sleeve 1.

[0080] Refer to Figure 7 、 Figure 8 A plurality of anti-slip grooves 19 can also be provided on the outside of the pipe sleeve 1, so as to make it easier to "hold" the pipe sleeve 1 when operating on the pipe sleeve 1.

[0081] The present disclosure has disclosed exemplary embodiments, and although specific terms are employed, they are used only and should be interpreted only as general illustrative meanings and not for the purpose of limitation. In some instances, it will be apparent to those skilled in the art that, unless otherwise expressly stated, features, characteristics, and / or elements described in connection with a particular embodiment may be used alone or in combination with features, characteristics, and / or elements described in connection with other embodiments. Accordingly, those skilled in the art will understand that various forms and details of changes may be made without departing from the scope of the present disclosure as set forth by the appended claims.
