Description

Technical Field

[0001] This invention relates to the field of optical fiber communication physical connection technology, and in particular to an optical fiber connector. Background Technology

[0002] Fiber optic connectors are used to quickly connect two optical fibers, enabling continuous optical signals and forming an optical path. Typically, a fiber optic connector consists of multiple components, assembled through the mating and connection of these components. Because fiber optic connectors require extremely high connection precision, assembly often requires a considerable amount of time to ensure all components are properly assembled. Improper assembly can significantly affect the connection accuracy of the fiber optic connector.

[0003] Furthermore, in fiber-to-the-home (FTTH) implementations, when the number of fiber optic cables is fixed, the only way to meet the fiber optic cable requirements is to increase the number or size of the fiber optic boxes. However, increasing the size of the fiber optic boxes leads to larger, less portable boxes; increasing the number of fiber optic boxes also increases the area or volume of the terminal box. For high-rise residents, space within the terminal box is limited, and excessively large fiber optic boxes can pose safety hazards, thus limiting the size of the fiber optic boxes.

[0004] However, in actual construction, the old large-size fiber optic boxes may already be in place. To improve the convenience of on-site construction and the safety of the fiber optic boxes, compact fiber optic boxes can be used to replace the old fiber optic boxes in the terminal box. This not only requires the fiber optic connectors to make stable, accurate and convenient connections, but also places higher demands on the compatibility of the fiber optic connectors.

[0005] Therefore, how to improve the convenience of fiber optic connectors while ensuring their connection stability and accuracy has become an urgent problem to be solved.

[0006] How to make fiber optic connectors compatible with different types of fiber optic boxes and improve the compatibility of fiber optic connectors has become another problem that urgently needs to be solved. Summary of the Invention

[0007] This invention provides an optical fiber connector that improves the convenience of optical fiber connectors while also ensuring connection stability and accuracy.

[0008] This invention provides an optical fiber connector, comprising a body, a collar, and a sleeve, wherein the collar and sleeve are fitted onto the body and detachably connected to the body, wherein...

[0009] The outer side wall of the main body is provided with a connecting groove and a guiding structure, and the inner side wall of the collar is provided with a first connecting part that matches the connecting groove. The guiding structure is used to guide the first connecting part to cooperate with the connecting groove to restrict the axial movement between the collar and the main body.

[0010] A guide structure is also provided on the outer side wall of the main body. The guide structure is a continuous structure. A mating part is provided on the inner side wall of the sleeve. The mating part is used to cooperate with the guide structure to restrict the circumferential rotation between the sleeve and the main body.

[0011] The collar is also provided with a second connecting part, and the sleeve is provided with a connecting rail. The second connecting part is used to cooperate with the connecting rail to connect the collar and the sleeve, and to restrict the circumferential rotation between the collar and the sleeve.

[0012] Optionally, the guide structure includes two continuous guide arms, with a guide channel provided between the two guide arms.

[0013] Optionally, an inlet groove is provided on the outer side of the main body along the circumferential direction, and the guide arm at least partially or completely separates the guide groove from the inlet groove.

[0014] Optionally, the inner wall of the inlet groove is chamfered.

[0015] Optionally, the main body is also provided with a snap-fit ​​part, which is located on the side opposite to the guide structure and is the side wall of the guide groove. The snap-fit ​​part is used to guide the connector of the external fiber optic box to the snap-fit ​​part through the guide groove when the fiber optic connector is fixedly connected to the external fiber optic box, thereby restricting the axial movement between the fiber optic connector and the external fiber optic box.

[0016] Optionally, a chamfer is provided on the inner wall of one side of the inlet groove, and the snap-fit ​​part is provided on the inner wall of the inlet groove where the chamfer is provided.

[0017] Optionally, the snap-fit ​​part is provided on the inner wall of the inlet groove, and the inner walls of the inlet groove on both sides of the snap-fit ​​part are provided with chamfers.

[0018] Optionally, a first limiting part is provided on the outer side wall of the main body, wherein the first limiting part is the side wall of the connecting groove, and the first connecting part cooperates with the first limiting part to restrict the axial movement of the collar and the main body in the first direction.

[0019] Optionally, one end of the connecting rail is provided with an opening, and the opening of the connecting rail is provided from the end face of the sleeve near the collar.

[0020] When the second connecting part mates with the connecting rail, the second connecting part fits against the connecting rail and moves from the opening of the connecting rail to the end to connect the collar and the sleeve.

[0021] Optionally, the connecting track section is curved.

[0022] This invention discloses an optical fiber connector, comprising a body, a collar, and a sleeve. The body is provided with a connecting groove, a guiding structure, and a guiding structure. The collar is provided with a first connecting part. The guiding structure guides the first connecting part to engage with the connecting groove, thereby restricting the axial movement between the collar and the body. The sleeve is provided with a mating part, which engages with the guiding structure to restrict the circumferential rotation between the sleeve and the body. Furthermore, by utilizing the engagement between a second connecting part on the collar and a connecting track on the sleeve, not only are the collar and the sleeve connected, but the circumferential rotation between the collar and the sleeve is also restricted. This solution first restricts the axial movement between the collar and the main body through the cooperation between the first connecting part and the connecting groove. Then, it restricts the axial rotation between the sleeve and the main body through the cooperation between the mating part and the guide structure. Finally, it restricts the circumferential movement between the collar and the sleeve through the cooperation between the collar and the sleeve, thereby restricting the circumferential rotation between the collar and the main body, as well as the axial movement between the sleeve and the main body. This not only achieves axial and circumferential positioning of each pair of collar, sleeve, and main body, ensuring the connection stability and accuracy of the fiber optic connector, but also makes the assembly of each component in the fiber optic connector more convenient, improving the convenience of the fiber optic connector. Furthermore, the fiber optic connector in this application is smaller in size, allowing it to be used in a more compact fiber optic box, thus being compatible with different models of fiber optic boxes and improving the compatibility of the fiber optic connector.

[0034] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail, but well-known methods, processes, and components are not described in detail in order to avoid obscuring the essence of the present invention.

[0035] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0036] Unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."

[0037] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0038] Please see Figure 1 , Figure 1 This is an exploded view of an optical fiber connector according to an embodiment of this application. The optical fiber connector includes a connector head 1, a body 2, a collar 3, a sleeve 4, a fixing member 5, and a dust cap 6. The collar 3 and the sleeve 4 are both fitted onto the body 2 and are detachably connected to the body 2.

[0039] Connector 1 is connected to body 2. In practice, connector 1 can be detachably connected to body 2 to facilitate the replacement of different types of connector 1; connector 1 can also be fixedly connected to body 2. In actual implementation, different types of connectors can also be selected according to the different third-party fiber optic connection equipment being adapted.

[0040] In one embodiment, connector 1 may be as follows: Figure 1 The single-core fiber optic connector shown can also be as follows: Figure 2 The multi-core fiber optic connector shown is an example. The specific type of fiber optic connector to use can be determined based on actual needs.

[0041] like Figure 1 As shown, the main body 2 has a slender structure. This slender structure results in a smaller axial cross-sectional area, allowing it to be used in more compact fiber optic boxes with a smaller overall size. Understandably, this slender fiber optic connector can also be used in older, larger fiber optic boxes, enabling it to adapt to different types and models of fiber optic boxes and improving its compatibility.

[0042] Please see Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of the main body in one direction of the fiber optic connector provided in the embodiments of this application. Figure 4 This application provides a schematic diagram of the structure of the main body of the optical fiber connector in another direction.

[0043] like Figure 3 and Figure 4 As shown, a connecting groove 24 and a guide structure 25 are provided on the outer side wall of the main body 2.

[0044] Please see Figure 6 , Figure 6 This is a schematic diagram of the ferrule in the fiber optic connector provided in an embodiment of this application.

[0045] like Figure 6 As shown, the inner sidewall of the collar 3 is provided with a first connecting part 31 that matches the connecting groove 24. The guide structure 25 is used to guide the first connecting part 31 to cooperate with the connecting groove 24 to restrict the axial movement between the collar 3 and the main body 2.

[0046] In practical implementation, when the collar 3 is fitted onto the main body 2, the first connecting portion 31 on the collar 3 enters the connecting groove 24 through the guide structure 25. The first connecting portion 31 cooperates with the connecting groove 24, thereby restricting the axial movement of the collar 3 on the main body 2, so that the collar 3 can only rotate circumferentially on the main body 2 with the connecting groove 24 as the track. In practical implementation, the thickness of the first connecting portion 31 can be less than the width of the connecting groove 24, so that the first connecting portion 31 can be completely engaged in the connecting groove 24.

[0047] It is understood that the length of the first connecting part 31 is less than or equal to the length of the guide structure 25. The length of the first connecting part 31 refers to the length of the main body 2 circumferentially. Only when the length of the first connecting part 31 is less than or equal to the length of the guide structure 25 can the first connecting part 31 pass through the guide structure 25 and enter the connecting groove 24.

[0048] In one embodiment, a first limiting part 21 is provided on the outer side wall of the main body 2. The first limiting part 21 is the side wall of the connecting groove 24. The first connecting part 31 cooperates with the first limiting part 21 to restrict the axial movement of the collar 3 and the main body 2 in the first direction. At this time, the guide structure 25 provided on the outer side wall of the main body 2 is a notch of a preset length provided on the second limiting part 22. There is at least one guide structure 25 on the main body 2, that is, at least one notch of a preset length can be provided on the second limiting part 22. When there are multiple notches, the length of each notch can be the same or different.

[0049] In specific implementation, a first limiting part 21 can be provided only on the main body 2 as a sidewall of the connecting groove 24, so that when the first connecting part 31 cooperates with the first limiting part 21, the axial movement of the collar 3 in the first direction can be restricted by the first limiting part 21. Here, the first direction refers to the direction from the end of the main body 2 away from the connector 1 towards the end of the main body 2 closer to the connector 1, that is... Figure 4 The arrow in the image indicates the direction.

[0050] It should be noted that the first limiting part 21 is not necessarily a protruding structure. When the first limiting part 21 is a protruding structure, the first connecting part 31 is a recessed structure, and when the connecting groove 24 is a recessed structure, the first connecting part 31 is a protruding structure.

[0051] In other embodiments, such as Figure 5 As shown, a second limiting part 22 can also be provided on the outer side wall of the main body 2, with a preset distance between the first limiting part 21 and the second limiting part 22 to form a connecting groove 24. The distance between the first limiting part 21 and the second limiting part 22 can be adjusted according to the actual situation. Similarly, the second limiting part 22 is not necessarily a protruding structure.

[0052] Please see Figure 7 , Figure 7 This is a schematic diagram of the sleeve structure in the fiber optic connector provided in the embodiment of this application.

[0053] like Figure 4 As shown, a guide structure 26 is also provided on the outer side wall of the main body 2, and the guide structure 26 is a continuous structure.

[0054] like Figure 7 As shown, a mating part 41 is provided on the inner wall of the sleeve 4. The mating part 41 is used to cooperate with the guide structure 26 to restrict the circumferential rotation between the sleeve 4 and the main body 2.

[0055] When the sleeve 4 is fitted onto the main body 2, the guide structure 26 on the main body 2 guides the sleeve 4. The sleeve 4 is guided and positioned by the cooperation between the guide structure 26 and the mating part 41, so that the sleeve 4 cannot rotate circumferentially on the main body 2.

[0056] In practice, the guide structure 26 can be either a protrusion or a groove. It is understood that when the guide structure 26 is a protrusion, the mating part 41 is a groove; when the guide structure 26 is a groove, the mating part 41 is a protrusion.

[0057] In one embodiment, such as Figure 4 As shown, the guide structure 26 includes two continuous guide arms 261, with a guide channel 262 between the two guide arms 261. The two guide arms 261 are arranged opposite each other along the axial direction of the main body 2, and the portion between the two guide arms 261 is the guide channel 262. In specific implementations, the guide channel 262 can be a protrusion or a groove.

[0058] In one embodiment, such as Figure 4 As shown, an inlet groove 28 is also provided circumferentially on the outer side of the main body 2, and a guide arm 261 at least partially or completely separates the guide channel 262 from the inlet groove 28. In specific implementation, the guide arm 261 at least partially separating the guide channel 262 from the inlet groove 28 means that the guide arm 261 is located between the guide channel 262 and the inlet groove 28. The guide arm 261 can completely separate the guide channel 262 from the inlet groove 28, or it can partially separate the guide channel 262 from the inlet groove 28.

[0059] In one embodiment, a chamfer is also provided on the inner sidewall of the inlet groove 28. In specific implementation, it can be done as follows: Figure 3 As shown, a chamfer is provided on the inner wall of one side of the inlet groove 28, and a chamfer is provided on the inner wall of the other side; alternatively, it can be as follows: Figure 8 As shown, a chamfer is provided on the inner wall of one side of the inlet groove 28, while the other side remains undesigned; alternatively, it can also be as follows: Figure 9 As shown, a chamfer is provided on the inner wall of one side of the inlet groove 28, while no other design is made on the other side. It can be understood that when providing a chamfer on the inner wall of the inlet groove 28, it can be provided continuously or intermittently.

[0060] In one embodiment, the main body 2 is further provided with a snap-fit ​​part 27, which is located on the side opposite to the guide structure 26. The snap-fit ​​part 27 is used to guide the connector of the external fiber optic box to the snap-fit ​​part 27 via the guide groove 28 when the fiber optic connector is fixedly connected to the external fiber optic box, thereby restricting the axial movement between the fiber optic connector and the external fiber optic box.

[0061] In the specific implementation process, when the fiber optic connector is fixedly connected to the external fiber optic box, the connector of the external fiber optic box will be guided into the snap-fit ​​part 27 through the guide groove 28 and abut against the snap-fit ​​part 27. Through the cooperation between the connector of the external fiber optic box and the snap-fit ​​part 27, the axial movement between the external fiber optic box and the fiber optic connector is restricted, thereby achieving the tensile strength of the fiber optic connector.

[0062] In one embodiment, a chamfer is provided on the inner sidewall of the guide groove 28 on one side, and the snap-fit ​​part 27 can also be provided on the chamfered inner sidewall of the guide groove 28. In specific implementation, the meaning of the snap-fit ​​part 27 being provided on the chamfered inner sidewall of the guide groove 28 is that the snap-fit ​​part 27 is the inner sidewall of the guide groove 28, that is, the chamfered part of the inner sidewall of the guide groove 28 is reused.

[0063] In another embodiment, the snap-fit ​​portion 27 is disposed on the inner sidewall of the guide groove 28, and chamfers are provided on the inner sidewalls of the guide groove 28 on both sides of the snap-fit ​​portion 27. In specific implementation, the snap-fit ​​portion 27 being disposed on the inner sidewall of the guide groove 28 means that the snap-fit ​​portion 27 is itself the inner sidewall of the guide groove 28, that is, a portion of the inner sidewall of the guide groove 28 is reused. In this case, chamfers can be provided on both sides of the snap-fit ​​portion 27, that is, on the inner sidewalls of the unreused portion of the guide groove 28. This allows the chamfers on both sides of the snap-fit ​​portion 27 to better limit the connection of the external fiber optic box when the fiber optic connector is fixedly connected to the external fiber optic box, thus securing the connection to the snap-fit ​​portion 27 and improving the tensile strength of the fiber optic connector.

[0064] like Figure 6 and Figure 7 As shown, the collar 3 is also provided with a second connecting part 32, and the sleeve 4 is provided with a connecting rail 42. The second connecting part 32 is used to cooperate with the connecting rail 42 to connect the collar 3 and the sleeve 4, and to restrict the circumferential rotation between the collar 3 and the sleeve 4.

[0065] When both the collar 3 and the sleeve 4 are fitted onto the main body 2, the sleeve 4 is partially covered by the collar 3. The connecting track 42 is located on the portion of the sleeve 4 covered by the collar 3. When the second connecting part 32 engages with the connecting track 42, the collar 3 and the sleeve 4 are connected together. Since the collar 3 is axially limited relative to the main body 2, and the collar 3 is connected to the sleeve 4, this also means that the sleeve 4 is axially limited relative to the main body 2. Similarly, since the sleeve 4 is circumferentially limited relative to the main body 2, and the collar 3 is connected to the sleeve 4, the collar 3 is also circumferentially limited relative to the main body 2. Thus, both the collar 3 and the sleeve 4 are limited relative to the main body 2 in both the circumferential and axial directions, achieving a tight connection between the main body 2, the collar 3, and the sleeve 4.

[0066] In one embodiment, such as Figure 6 As shown, a limiting platform 33 is also provided inside the collar 3. The limiting platform 33 is a ring platform. When the collar 3 is connected to the sleeve 4, the end face of the sleeve 4 near the collar 3 abuts against the limiting platform 33. The sleeve 4 covers the main body 2 and the sleeve 4 is at least partially covered by the collar 3.

[0067] A ring-shaped limiting platform 33 is provided inside the collar 3. When both the collar 3 and the sleeve 4 are covered on the main body 2, the sleeve 4 is partially covered by the collar 3. The collar 3 and the sleeve 4 are connected by the cooperation between the second connecting part 32 and the connecting track 42. At this time, the end face of the sleeve 4 close to the collar 3, that is, the end face of the sleeve 4 inside the collar 3, abuts against the limiting platform 33.

[0068] In one embodiment, the connecting rail 42 may be a threaded structure. When the connecting rail 42 is a threaded structure, the second connecting part 32 is a thread that mates with the connecting rail 42. It is understood that when the connecting rail 42 is an external thread, the second connecting part 32 is an internal thread; when the connecting rail 42 is an internal thread, the second connecting part is an external thread.

[0069] In one embodiment, such as Figure 7 As shown, one end of the connecting track 42 is provided with an opening, and the opening of the connecting track 42 is provided from the end face of the sleeve 4 near the collar 3; when the second connecting part 32 is engaged with the connecting track 42, the second connecting part 32 fits against the connecting track 42 and moves from the opening of the connecting track 42 to the end to connect the collar 3 and the sleeve 4.

[0070] One end of the connecting rail 42 is provided with an opening, and the opening of the connecting rail 42 starts from the end face of the sleeve 4. When the second connecting part 32 is engaged with the connecting rail 42, the second connecting part 32 can directly enter the connecting rail 42 from the opening of the connecting rail 42 until it moves to the end of the rail. During this process, the second connecting part 32 always fits the connecting rail 42 to ensure the tightness of the connection between the collar 3 and the sleeve 4.

[0071] In practice, the connecting track 42 can be either a concave or convex track. When the connecting track 42 is a concave track, the second connecting part 32 is a convex structure; when the connecting track 42 is a convex track, the second connecting part 32 is a concave structure.

[0072] In one embodiment, the connecting track 42 is arc-shaped. In practice, the angle of the arc-shaped portion of the connecting track 42 is not limited.

[0073] When the main body 2, collar 3 and sleeve 4 are all securely connected, although the collar 3 and sleeve 4 are limited in both the circumferential and axial directions, a certain degree of relative rotation can still occur between the collar 3 and sleeve 4 within the stroke of the connecting track 42. Therefore, by setting part of the connecting track 42 as an arc-shaped structure, the second connecting part 32 will not fall off on its own without external force after entering the connecting track 42, thereby increasing the tensile strength of the fiber optic connector and improving the connection stability and connection accuracy of the fiber optic connector.

[0074] In one embodiment, such as Figure 1 As shown, the fiber optic connector also includes a fixing member 5. An annular protrusion 43 is provided on the outer wall of the sleeve 4. The fixing member 5 covers the outer side of the collar 3 and the sleeve 4, and one end of the fixing member 5 abuts against the annular protrusion 43. In specific implementation, the end of the fixing member 5 that abuts against the annular protrusion 43 is provided with an external thread for threaded connection with a third-party fiber optic connection device, thereby achieving a secure connection between the fiber optic connector and the third-party fiber optic connection device.

[0075] In one embodiment, such as Figure 3 As shown, an external thread 23 is provided on the outer side wall of the main body 2 along the circumferential direction, and a guide structure 25 is also provided on the external thread 23.

[0076] In practice, the guide structure 25 on the external thread 23 is the same as the guide structure 25 on the main body 2. That is, when the guide structure 25 is a notch, the external thread 23 also has a notch. However, it is understood that the length of the guide structure 25 on the main body 2 and the length of the guide structure 25 on the external thread 23 can be different, but the length of the guide structure 25 on the external thread 23 must be greater than or equal to the length of the guide structure 25 on the main body 2.

[0077] Please see Figure 10 , Figure 10 This is another exploded structural diagram of the fiber optic connector provided in the embodiments of this application.

[0078] like Figure 10As shown, the fiber optic connector also includes a dust cap 6, the inner wall of which is provided with an internal thread 61, which matches the external thread 23.

[0079] When the fiber optic connector does not need to be assembled and used, the collar 3 and sleeve 4 can be removed from the main body 2, and the dust cap 6 can be replaced. The dust cap 6 and the main body 2 are fastened together by the internal thread 61 on the dust cap 6 and the external thread 23 on the main body 2, so as to prevent dust, flying lint and other impurities from entering the fiber optic connector and affecting the subsequent use of the fiber optic connector.

[0080] In one embodiment, such as Figure 1 and Figure 10 As shown, the fiber optic connector also includes a tail sleeve 7. The tail sleeve 7 is detachably connected to the end of the body 2 away from the connector head 1, and the tail sleeve 7 has a hollow structure for passing through the fiber optic cable.

[0081] This invention discloses an optical fiber connector, comprising a body, a collar, and a sleeve. The body is provided with a connecting groove, a guiding structure, and a guiding structure. The collar is provided with a first connecting part. The guiding structure guides the first connecting part to engage with the connecting groove, thereby restricting the axial movement between the collar and the body. The sleeve is provided with a mating part, which engages with the guiding structure to restrict the circumferential rotation between the sleeve and the body. Furthermore, by utilizing the engagement between a second connecting part on the collar and a connecting track on the sleeve, not only are the collar and the sleeve connected, but the circumferential rotation between the collar and the sleeve is also restricted. This solution first restricts the axial movement between the collar and the main body through the cooperation between the first connecting part and the connecting groove. Then, it restricts the axial rotation between the sleeve and the main body through the cooperation between the mating part and the guide structure. Finally, it restricts the circumferential movement between the collar and the sleeve through the cooperation between the collar and the sleeve, thereby restricting the circumferential rotation between the collar and the main body, as well as the axial movement between the sleeve and the main body. This not only achieves axial and circumferential positioning of each pair of collar, sleeve, and main body, ensuring the connection stability and accuracy of the fiber optic connector, but also makes the assembly of each component in the fiber optic connector more convenient, improving the convenience of the fiber optic connector. Furthermore, the fiber optic connector in this application is smaller in size, allowing it to be used in a more compact fiber optic box, thus being compatible with different models of fiber optic boxes and improving the compatibility of the fiber optic connector.

[0082] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
