Description

Technical Field

[0001] This application relates to the field of fiber optic connector technology, and in particular to a fiber optic connector protective housing assembly. Background Technology

[0002] With the large-scale application of Fiber To The Home (FTTH), a large number of fiber optic connectors are inevitably needed. Fiber optic connectors are the most widely used passive optical devices in fiber optic communication systems. Most fiber optic connectors consist of three parts: two fiber optic connectors and a coupler; the two fiber optic connectors are used to insert the two fiber optic tails; and the coupler serves to align the ferrules. Fiber optic connectors have a wide range of applications, and during long-term use, especially outdoors, fiber optic adapters need to be waterproof.

[0003] In related technologies, fiber optic connectors used outdoors need to have good waterproof performance. To achieve this, a protective sleeve is usually added to the fiber optic connector. One end of the protective sleeve is connected to a waterproof sealing plug that seals the protective sleeve, and the other end is connected to a waterproof sealing cap that seals the protective sleeve. The enclosed space formed by the protective sleeve, the waterproof sealing plug, and the waterproof sealing cap provides waterproof, dustproof, and weather-resistant protection for the fiber optic connector.

[0004] When installing the fiber optic connector in the enclosed space formed by the outer protective sleeve, waterproof sealing plug, and waterproof sealing cap, it is necessary to first disassemble the assembled outer protective sleeve, waterproof sealing plug, and waterproof sealing cap into individual parts. Then, assemble the fiber optic connector inside the outer protective sleeve, then attach the waterproof sealing plug to the optical cable at the end of the fiber optic connector and seal it to one end of the outer protective sleeve. Finally, connect the waterproof sealing cap to the other end of the outer protective sleeve.

[0005] However, during the installation and removal of the aforementioned outer protective sleeve, waterproof sealing plug, and waterproof sealing cap, their small size and light weight make them prone to slipping from the hands of workers. This is especially problematic when workers are operating at heights; the falling of these components can impede their work and reduce efficiency. Summary of the Invention

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] This application provides a fiber optic connector protective housing assembly that solves the problem in related technologies where the waterproof sealing plugs and waterproof sealing caps at both ends of the protective sleeve are easily slipped from the hands of operators due to their small size and light weight.

[0049] See Figures 1 to 4 As shown, the first aspect of this application provides a fiber optic connector protective housing assembly, including:

[0050] The outer protective kit 10 includes an outer protective sleeve 11 for accommodating the fiber optic connector 30, a waterproof sealing cap 13 sealing the front end of the outer protective sleeve 11, and a waterproof sealing plug 12 sealing the end of the outer protective sleeve 11. The waterproof sealing plug 12 has a through hole 121 for inserting the optical cable 31.

[0051] A fall arresting rope 20 is attached to the outer protective sleeve 11. One end of the fall arresting rope 20 is detachably connected to a waterproof sealing plug 12, and the other end is rotatably connected to a waterproof sealing cover 13. The waterproof sealing plug 12 is plugged into and detached from one end of the fall arresting rope 20, facilitating the assembly of the waterproof sealing plug 12 and the fall arresting rope 20 together.

[0052] The outer protective sleeve 11 has a hollow tube structure, and a cavity is formed inside the outer protective sleeve 11 to accommodate the fiber optic connector 30. The front end of the outer protective sleeve 11 has a front opening that communicates with the cavity, and the end of the outer protective sleeve 11 has an end opening that communicates with the cavity. A waterproof sealing plug 12 is sealed to the end of the outer protective sleeve 11 to close the end opening.

[0053] The waterproof sealing cap 13 is threaded onto the front end of the outer protective sleeve 11 to close the front opening. The waterproof sealing cap 13 can be either a dust cap or an adapter that is threaded onto the outer protective sleeve 11. The waterproof sealing cap 13 is rotatably connected to the fall arrestor rope 20 to facilitate the threaded connection between the waterproof sealing cap 13 and the outer protective sleeve 11.

[0054] Before the outer protective sleeve 11 is connected to the adapter, a dust cap is used to connect the outer protective sleeve 11 to form a waterproof and enclosed space for accommodating the fiber optic connector 30; when the outer protective sleeve 11 is connected to the adapter, the adapter is used to connect the outer protective sleeve 11 to form a waterproof and enclosed space for accommodating the fiber optic connector 30.

[0055] When the dust cap is connected to the outer protective sleeve 11 via the fall arrestor rope 20, the fall arrestor rope 20 is used to prevent the dust cap from falling. When the adapter is connected to the outer protective sleeve 11 via the fall arrestor rope 20, the fall arrestor rope 20 is used to prevent the outer protective sleeve 11 from falling.

[0056] The outer protective sleeve 10 of the fiber optic connector protective housing assembly in this application embodiment uses an outer protective sleeve 11, a waterproof sealing plug 12, and a waterproof sealing cap 13 to form a waterproof enclosed space for accommodating the fiber optic connector 30.

[0057] During assembly, the fiber optic connector 30 is first inserted into the outer protective sleeve 11, and then the waterproof sealing plug 12 is fitted onto the optical cable 31 at the end of the fiber optic connector 30 and then sealed to the end of the outer protective sleeve 11.

[0058] Finally, the waterproof sealing cap 13 is sealed to the front end of the outer protective sleeve 11 to seal the fiber optic connector 30 inside the outer protective kit 10, thereby improving the sealing and waterproof performance and enabling the use of the ordinary pre-assembled fiber optic connector 30 in outdoor scenarios requiring waterproof performance.

[0059] In addition, the fiber optic connector protective shell assembly of this application embodiment is provided with a fall protection rope 20 on the outer protective sleeve 11. One end of the fall protection rope 20 is detachably connected to the waterproof sealing plug 12, and the other end of the fall protection rope 20 is rotatably connected to the waterproof sealing cover 13.

[0060] The fall arrestor rope 20 connects the waterproof sealing plug 12 and the waterproof sealing cover 13 to the outer protective sleeve 11. When installing and removing the waterproof sealing plug 12 and the waterproof sealing cover 13, the waterproof sealing plug 12 and the waterproof sealing cover 13 are always connected to the outer protective sleeve 11, eliminating the risk of workers falling while working at height and improving the efficiency of construction operations.

[0061] In some alternative implementations: see Figure 4 As shown, this application embodiment provides a fiber optic connector protective shell assembly. The waterproof sealing plug 12 of the fiber optic connector protective shell assembly is made of flexible sealing material. A cutout 122 is radially opened on the outer wall of the waterproof sealing plug 12, which communicates with the wire through hole 121. The length of the cutout 122 extends through both ends of the waterproof sealing plug 12.

[0062] A bevel 123 is provided on the outer wall of the waterproof sealing plug 12, located on both sides of the cut 122. The bevel extends to one end of the waterproof sealing plug 12, and the bevel 123 has a "V" or "U" shaped structure. When the waterproof sealing plug 12 is fitted onto the optical cable 31 at the end of the optical fiber connector 30, the cut 122 is opened from the closed state by hand or with a tool from the bevel 123 position, and the waterproof sealing plug 12 is fitted onto the optical cable 31 through the cut 122.

[0063] In some alternative implementations: see Figures 1 to 4 As shown, this application embodiment provides a fiber optic connector protective shell assembly. The waterproof sealing plug 12 of the fiber optic connector protective shell assembly has a cylindrical structure, and the diameter of the waterproof sealing plug 12 gradually decreases from the middle to both ends. The end opening of the outer protective sleeve 11 is a flared mouth 111 adapted to the diameter of the waterproof sealing plug 12.

[0064] A first nut 14 is threaded to the end of the outer protective sleeve 11 to secure the waterproof sealing plug 12 inside the outer protective sleeve 11. One end of the fall arrest rope 20 is inserted into the first nut 14 and then connected to the waterproof sealing plug 12. When the first nut 14 is threaded to the end of the outer protective sleeve 11, the waterproof sealing plug 12 is squeezed and secured inside the flared opening 111.

[0065] The inner diameter of the first nut 14 is smaller than the outer diameter of the waterproof sealing plug 12. When one end of the fall arrest rope 20 is inserted into the first nut 14 and connected to the waterproof sealing plug 12, the first nut 14 is fitted onto the fall arrest rope 20 by the waterproof sealing plug 12, preventing the first nut 14 from falling when installing or removing the waterproof sealing plug 12.

[0066] In some alternative implementations: see Figures 1 to 4 As shown, this application embodiment provides a fiber optic connector protective housing assembly. The anti-fall pull rope 20 of the fiber optic connector protective housing assembly includes a first ring 21 sleeved on the outer wall of the outer protective sleeve 11, and a first pull rope 22 connected to the waterproof sealing plug 12 is provided on the first ring 21.

[0067] And a second ring 23 fitted on the outer wall of the waterproof sealing cover 13, a second pull rope 24 connected to the first ring 21 is provided on the second ring 23, and an annular groove connected to the second ring 23 is provided on the outer wall of the waterproof sealing cover 13 so that the waterproof sealing cover 13 can rotate freely relative to the second ring 23.

[0068] In this embodiment, the first pull cord 22 is connected between the first ring 21 and the waterproof sealing plug 12, and the second pull cord 24 is connected between the second ring 23 and the first ring 21. The first pull cord 22 is plugged into one end of the waterproof sealing plug 12. The first pull cord 22 and the second pull cord 24 are bent into a "U" shape.

[0069] See Figures 5 to 7 As shown, a second aspect of this application provides a fiber optic connector protective housing assembly, comprising:

[0070] The outer protective kit 10 includes an outer protective sleeve 11 for accommodating the fiber optic connector 30, a waterproof sealing cap 13 sealing the front end of the outer protective sleeve 11, and a waterproof sealing plug 12 sealing the end of the outer protective sleeve 11. The waterproof sealing plug 12 has a through hole 121 for inserting the optical cable 31.

[0071] The outer protective sleeve 11 includes a front sleeve 112 and a rear sleeve 113 that are coaxial and axially slidably connected, with the rear sleeve 113 partially located inside the front sleeve 112. The front end of the front sleeve 112 is threadedly connected to the waterproof sealing cap 13, and the end of the rear sleeve 113 is threadedly connected to a second nut 15 that fixes the waterproof sealing plug 12 inside the rear sleeve 113.

[0072] The outer protective sleeve 11 of this application embodiment includes a front sleeve 112 and a rear sleeve 113 that are coaxially connected and axially slidably connected. The rear sleeve 113 is partially located inside the front sleeve 112. The front sleeve 112 and the rear sleeve 113 can be axially slidably adjusted to adjust the length of the outer protective sleeve 11, thereby allowing the outer protective sleeve 11 to accommodate fiber optic connectors 30 of different lengths and improving the versatility of the outer protective kit 10.

[0073] In some alternative implementations: see Figure 7 As shown, this application embodiment provides a fiber optic connector protective shell assembly. The fiber optic connector protective shell assembly has a first sealing ring 17 between the front sleeve 112 and the rear sleeve 113 for mutual sealing connection. The first sealing ring 17 is used to seal the gap between the front sleeve 112 and the rear sleeve 113 to improve the waterproof performance of the connection between the front sleeve 112 and the rear sleeve 113.

[0074] The front end of the rear sleeve 113 is threadedly connected to a connector 16 that positions the fiber optic connector 30 axially and circumferentially on the rear sleeve 113. The connector 16's threaded connection to the front end of the rear sleeve 113 facilitates installation and removal of the connector 16 from the rear sleeve 113, and allows for easy replacement of the connector 16 to accommodate different types of fiber optic connectors 30. The connector 16 is compatible with any of the following connector types: SC, FC, LC, ST, and XC.

[0075] In some alternative implementations: see Figure 7 and Figure 10 As shown, this application embodiment provides a fiber optic connector protective shell assembly. The connector 16 of the fiber optic connector protective shell assembly includes an inner sleeve 161 that is threadedly connected to the front end of the rear sleeve 113. The front end of the inner sleeve 161 is provided with a positioning slot 162 that connects to and partially accommodates the fiber optic connector 30.

[0076] Two centrally symmetrically arranged elastic arms 163 extend from the front end of the inner sleeve 161. The elastic arms 163 are provided with barbs 164 for axially positioning the fiber optic connector 30 in the positioning slot 162. A notch 165 is radially opened on the outer wall of the inner sleeve 161, communicating with the inner wall of the inner sleeve 161. The notch 165 extends to both ends of the inner sleeve 161.

[0077] In this embodiment, a positioning slot 162 is provided at the front end of the inner sleeve 161 to connect to and partially accommodate the fiber optic connector 30. The outer shell of the fiber optic connector 30 can be snapped into the positioning slot 162 to achieve axial and circumferential positioning. Furthermore, two elastic arms 163 extend from the front end of the inner sleeve 161, and barbs 164 provided on the elastic arms 163 are used to snap the fiber optic connector 30 to prevent the fiber optic connector 30 from coming out of the positioning slot 162.

[0078] When assembling the fiber optic connector 30 onto the connector 16, first, the inner sleeve 161 is fitted onto the optical cable 31 at the end of the fiber optic connector 30 through the notch 165. Then, the fiber optic connector 30 is inserted into the positioning slot 162 of the inner sleeve 161 until the barb 164 on the elastic arm 163 is engaged with the outer shell of the fiber optic connector 30, thereby positioning the fiber optic connector 30 circumferentially and axially on the connector 16.

[0079] In some alternative implementations: see Figures 6 to 9 As shown in the figure, this application embodiment provides a fiber optic connector protective shell assembly. One end of the second nut 15 of the fiber optic connector protective shell assembly has an external thread 151 that is threaded to the end of the rear sleeve 113, and the other end of the second nut 15 has a polygonal inner hole 152. The waterproof sealing cap 13 has a polygonal head 131 that is adapted to the polygonal inner hole 152 at the end away from the front sleeve 112, and the axis of the polygonal head 131 is perpendicular to the axis of the waterproof sealing cap 13.

[0080] In this embodiment, the second nut 15 is threadedly connected to the end of the rear sleeve 113 via an external thread 151 to seal and fix the waterproof sealing plug 12 inside the rear sleeve 113. A polygonal inner hole 152 is provided at the other end of the second nut 15. The polygonal head 131 at the front end of the waterproof sealing cap 13 is adapted to the polygonal inner hole 152 for tightening the second nut 15 onto the rear sleeve 113. The polygonal inner hole 152 is preferably, but not limited to, a hexagonal inner hole, and the polygonal head 131 is preferably, but not limited to, a hexagonal head.

[0081] When threading the second nut 15 to the end of the rear sleeve 113, you can first hold the second nut 15 and pre-connect it to the rear sleeve 113, then remove the waterproof sealing cap 13, insert the polygonal head 131 of the waterproof sealing cap 13 into the polygonal inner hole 152 of the second nut 15, and tighten the second nut 15 onto the rear sleeve 113 by rotating the waterproof sealing cap 13, thereby improving the waterproof sealing performance of the waterproof sealing plug 12.

[0082] In some alternative implementations: see Figures 6 to 9 As shown in the figure, this application embodiment provides a fiber optic connector protective shell assembly. The second nut 15 of the fiber optic connector protective shell assembly includes a left half nut 153 and a right half nut 154 that are mated to each other. One end of the left half nut and the right half nut together forms an external thread 151 that is threaded to the end of the rear sleeve 113. The other ends of the left half nut 153 and the right half nut 154 together form a polygonal inner hole 152.

[0083] In this embodiment, the second nut 15 is divided into a left half nut 153 and a right half nut 154. The left half nut 153 and the right half nut 154 are designed as separate units, which facilitates the disassembly and assembly of the left half nut 153 and the right half nut 154 onto the optical cable 31. After the left half nut 153 and the right half nut 154 are fitted onto the optical cable 31, they are then joined together to form the second nut 15, which is then threaded to the end of the rear sleeve 113.

[0084] One end of the waterproof sealing cap 13 is provided with a second sealing ring 18 that is sealed to the front sleeve 112. The polygonal head 131 is provided with a clearance groove 132 for avoiding the optical cable 31. The waterproof sealing cap 13 is threaded to the front sleeve 112, and the second sealing ring 18 is sealed between the waterproof sealing cap 13 and the front sleeve 112, thereby improving the waterproof sealing performance at the connection between the waterproof sealing cap 13 and the front sleeve 112.

[0085] The polygonal head 131 has a clearance groove 132 for avoiding the optical cable 31. This clearance groove 132 is used to avoid the optical cable 31 located inside the polygonal inner hole 152 when the polygonal head 131 is inserted into the second nut 15. After the optical cable 31 is located in the clearance groove 132, the waterproof sealing cap 13 can rotate around the optical cable 31 to smoothly tighten the second nut 15 onto the rear sleeve 113.

[0087] This application provides a fiber optic connector protective housing assembly. The fiber optic connector protective housing assembly includes an outer protective sleeve 10, which comprises an outer protective tube 11 for accommodating a fiber optic connector 30, a waterproof sealing cap 13 sealing the front end of the outer protective tube 11, and a waterproof sealing plug 12 sealing the end of the outer protective tube 11. The waterproof sealing plug 12 has a threading hole 121 for inserting an optical cable 31. A fall arrestor 20 is also provided, connected to the outer protective tube 11. One end of the fall arrestor 20 is detachably connected to the waterproof sealing plug 12, and the other end is rotatably connected to the waterproof sealing cap 13.

During assembly, the fiber optic connector 30 is first inserted into the outer protective sleeve 11, then the waterproof sealing plug 12 is fitted onto the optical cable 31 at the end of the fiber optic connector 30 and then sealed to the end of the outer protective sleeve 11. Finally, the waterproof sealing cap 13 is sealed to the front end of the outer protective sleeve 11 to seal the fiber optic connector 30 within the outer protective kit 10, thereby improving sealing performance and waterproof performance, and enabling the use of ordinary pre-assembled fiber optic connectors in outdoor scenarios requiring waterproof performance.

[0089] Furthermore, the fiber optic connector protective housing assembly of this application is equipped with a fall arrest rope 20 on the outer protective sleeve 11. One end of the fall arrest rope 20 is detachably connected to the waterproof sealing plug 12, and the other end is rotatably connected to the waterproof sealing cover 13. The fall arrest rope 20 connects the waterproof sealing plug 12 and the waterproof sealing cover 13 to the outer protective sleeve 11. When installing and removing the waterproof sealing plug 12 and the waterproof sealing cover 13, they are always connected to the outer protective sleeve 11, eliminating the risk of workers falling while working at heights and improving construction efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0091] It should be noted that in this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0092] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
