In an implementation, the fastener 4 may be threadably coupled to the housing 3. When the fastener 4 is provided with internal threads, the threads arranged at the corresponding positions on the shell 3 are external threads; when the external thread is provided on the fastener 4, the thread provided at the corresponding position on the housing 3 is an internal thread.

As shown in fig. 4, the main body 2 is provided with a first cavity 21, a second cavity 22 and a guiding structure 23 which is communicated with the first cavity 21 and the second cavity 22, wherein the guiding structure 23 is used for guiding the optical fiber cable 5 to be in butt joint with the embedded optical fiber 11; at least part of the quick-connect assembly 1 is arranged in the first cavity 21 and is fixedly connected with the main body 2, and the optical fiber cable 5 penetrates into the second cavity 22 through the fastener 4 and is in butt joint with the embedded optical fiber 11 through the guide structure 23.

In a specific implementation process, the first cavity 21 is used for being installed in cooperation with the quick-connect assembly 1, for example, the first cavity may be connected by a threaded connection, or may be connected by a buckle or the like. The second cavity 22 is adapted to cooperate with the optical fiber cable 5 for the optical fiber cable 5 to pass through. The guide structure 23 may be a channel axially arranged in the body 2. Preferably, the guide structure 23 may be axially disposed along the central axis of the body 2.

In the field installation process, an installer can use an optical fiber cutting knife to cut the optical fiber in the optical fiber cable 5 on the field, then penetrate the cut optical fiber cable 5 into the second cavity 22 of the main body 2 through the channel inside the fastener 4, then enter the guide structure 23 through the second cavity 22, and the guide structure 23 can limit and guide the position of the optical fiber cable 5 when the optical fiber in the optical fiber cable 5 extends out of the second cavity 22 to be butted with the embedded optical fiber 11, so that the optical fiber in the optical fiber cable 5 can be accurately butted with the embedded optical fiber 11 along the guide structure 23, the integral optical fiber connection precision of the optical fiber in the optical fiber cable 5 and the embedded optical fiber 11 is ensured, the optical fiber connection inside the outdoor waterproof quick connector 100 is further completed, and the optical fiber connection precision of the outdoor waterproof quick connector 100 is ensured after the optical fiber cable 5 is connected.

Further, the embedded optical fiber 11 is arranged in the quick-connection component 1, the quick-connection component 1 is arranged in the main body 2 and is in fastening connection with the main body 2, so that the quick-connection component 1 is not easy to separate from the main body 2, the connection tightness between the components in the outdoor waterproof quick connector 100 is good, and the precision of optical fiber connection and the tensile effect of the outdoor waterproof quick connector 100 can be ensured.

As shown in fig. 3, the housing 3 is provided with a receiving cavity 33, and the main body 2 may be at least partially located in the receiving cavity 33 of the housing 3 when the main body 2 is fixedly coupled with the housing 3.

As shown in fig. 5 and 6, the housing 3 includes a sinking structure 31 and an introduction groove 32, the introduction groove 32 being provided along an axial direction of the housing 3, the sinking structure 31 including an abutment surface 311, the abutment surface 311 having an angle of 100 ° or less with respect to the axis of the housing 3. The housing 3 is mated with the fiber optic box insertion port through the sinking structure 31 and the lead-in groove 32 to interface the outdoor waterproof quick connector 100 with the fiber optic box.

In a specific implementation, an axis intersecting the abutment surface 311 may be taken on the housing 3 to calculate the angle between the axis and the abutment surface 311. It is understood that the axis of the housing 3 refers to a line parallel to the central axis of the housing 3.

When the outdoor waterproof quick connector 100 and the optical fiber box are installed, the guide groove 32 arranged in the axial direction of the shell 3 can guide an installer to install the outdoor waterproof quick connector 100 into the insertion port 210 of the optical fiber box 200, and the sinking structure 31 arranged on the shell 3 can enable the outdoor waterproof quick connector to be clamped with the locking structure 230 in the optical fiber box 200, so that the outdoor waterproof quick connector 100 is clamped with the optical fiber box 200, and accurate connection between the outdoor waterproof quick connector 100 and the optical fiber box 200 is realized. Specifically, the locking structure 230 abuts against the abutting surface 311 on the housing 3, and the abutting surface 311 is used for limiting the position of the locking structure 230, so as to ensure the connection stability between the fiber optic box 200 and the housing 3, and further ensure the connection stability between the outdoor waterproof quick connector 100 and the fiber optic box 200.

In this embodiment, through the first cavity 21, the second cavity 22 and the guiding structure 23 in the main body 2, the optical fiber in the optical fiber cable 5 can be precisely abutted with the embedded optical fiber 11 along the preset connection direction and connection position, so that the overall optical fiber connection precision of the outdoor waterproof quick connector is ensured. In addition, by providing the sinking structure 31 and the introduction groove 32 on the housing 3, the entire outdoor waterproof quick connector 100 is aligned with the insertion port 210 of the optical fiber box 200. The optical fibers 11 and the optical fibers in the optical fiber cable 5 are aligned, the outdoor waterproof quick connector 100 and the optical fiber box 200 are aligned and connected, so that accurate butt joint between the optical fibers in the optical fiber cable 5 and the built-in optical fiber connector 220 of the optical fiber box 200 is realized, the conduction of the whole optical fiber circuit is realized, and the integral connection precision of the whole optical fiber connection assembly is ensured. In addition, the guiding structure 23 is arranged in the main body 2, the sinking structure 31 and the guiding groove 32 are arranged on the shell 3, so that the quick installation can be assisted by an installer, and the quick installation is realized, and meanwhile, the optical fiber connection precision is ensured.

Specifically, when a constructor discovers that the outdoor waterproof quick connector is damaged accidentally at a construction site, or the actual required length of a customer for the optical fiber cable 5 is uncertain, when the customer needs to perform emergency assembly on the construction site, the embedded optical fiber 11 is arranged in the quick-connect assembly 1, and the optical fiber in the optical fiber cable 5 is in butt joint with the embedded optical fiber 11 through the guide structure 23, and the butt joint mode not only improves the assembly and connection efficiency between the outdoor waterproof quick connector 100 and the optical fiber cable 5, but also can reduce the waiting time for factory production and processing, the assembly transportation time and the like due to the field assembly, so that the efficiency of the whole wiring engineering is improved.

Besides, as the sinking structure 31 and the leading-in groove 32 are not arranged on the shell 3, other nuts or buckle structures which are matched and connected with the female end are not arranged, the whole size of the outdoor waterproof quick connector is smaller, for example, the outer diameter size can be not more than 13mm, thereby improving the convenience of operation of constructors, reducing the operation technical requirements on the constructors and saving the comprehensive wiring cost.

In an embodiment, as shown in fig. 5, the sinker structure 31 may further include a bottom surface 312 intersecting the abutment surface 311. The bottom surface 312 may be parallel to the axis of the housing 3 or may have a certain angle.

In another embodiment, as shown in fig. 7, the housing 3 includes: the window 35, the guiding structure 23 is provided with an opening, and the position of the window 35 corresponds to the position of the opening. At this time, the side surface of the window 35 along the circumferential direction of the housing 3 is the abutment surface 311 in the sinking structure 31.

Preferably, the position of the opening can be set at the cavity where the pre-buried optical fiber 11 and the optical fiber cable 5 are in butt joint on the guiding structure 23, and the position of the window 35 corresponds to the position of the opening, so that a constructor can observe the butt joint condition between the internal optical fiber cable 5 and the pre-buried optical fiber 11 through the window 35.

The condition of the butt joint between the optical fiber cable 5 and the embedded optical fiber 11 can be observed through the window 35, and it is not necessary to observe the optical fiber cable 5 and the embedded optical fiber 11 in the window 35 at the same time, and it is only necessary to determine the butt joint condition between the optical fiber cable 5 and the embedded optical fiber 11 according to the content observed in the window 35. For example, only the optical fiber in the optical fiber cable 5 can be seen through the window 35, specifically, when the optical fiber in the optical fiber cable 5 is pushed to a certain extent in the direction of the embedded optical fiber 11, the optical fiber in the optical fiber cable 5 receives a certain resistance, so that a certain shape of bending occurs, and at this time, the optical fiber cable 5 and the embedded optical fiber 11 can be considered to be coupled in place, and the butt joint is completed.

It will be appreciated that the shape and size of the opening and the shape and size of the window 35 are not particularly limited, and the size of the opening may be smaller than the size of the window 35 or larger than the size of the window 35, but it is required that the opening and the window 35 at least partially overlap, that is, the constructor can observe the abutting condition between the optical fiber cable 5 and the embedded optical fiber 11 inside the guiding structure 23 through the overlapping portion.

In some embodiments, to prevent poor sealing at the window 35, a window cover may be provided at the window 35 to improve sealing.

In this embodiment, the window 35 is configured to enable an installer to directly observe the butt joint condition between the embedded optical fiber 11 and the optical fiber cable 5, so that the installer can conveniently and accurately install the optical fiber.

At this time, at least part of the side surfaces of the mounting groove 36 are the abutment surfaces 311 of the sinking structure 31.

In an embodiment, at least one annular groove is further arranged on the outer side of the shell 3 along the circumferential direction, and a sealing ring is arranged in each annular groove, so that when the outdoor waterproof quick connector 100 is matched and connected with the optical fiber box 200, the sealing ring on the shell 3 can play a waterproof role between the outdoor waterproof quick connector 100 and the optical fiber box 200. Preferably, the number of the sealing rings is two.

In one embodiment, as shown in fig. 4, an end of the guiding structure 23 near the first cavity 21 is provided with a fixing cavity 231, the fixing cavity 231 is communicated with the first cavity 21, an end of the quick-connect assembly 1 is provided with a matching portion 12, and the matching portion 12 extends into the fixing cavity 231 and is connected with the fixing cavity 231 in a matching manner.

In a specific implementation process, at the connection position of the first cavity 21 and the fixed cavity 231, the diameter of the fixed cavity 231 is larger than that of the first cavity 21 at the connection position of the first cavity 21 and the fixed cavity 231, and the maximum diameter of the matching part 12 is also larger than that of the first cavity 21 at the connection position of the first cavity 21 and the fixed cavity 231, so that the matching part 12 can be matched and connected with the fixed cavity 231, the quick-connection assembly 1 is kept in the main body 2, the quick-connection assembly 1 can not move to the side far away from the guide structure 23, and the quick-connection assembly 1 is fastened and connected with the main body 2. On this basis, the shape of the fitting portion 12 is not limited, and may be irregular or regular, and the circumferential direction of the fitting portion 12 may have a certain elasticity.

For example, the shape of the mating portion 12 may be conical or truncated cone, so that the quick-connect assembly 1 can more conveniently enter the fixing cavity 231, and when the quick-connect assembly 1 needs to be withdrawn reversely, the quick-connect assembly 1 receives a large resistance, so as to ensure the stability of the connection between the quick-connect assembly 1 and the main body 2.

It can be understood that the quick-connect assembly 1 may be fastened to the main body 2 by other means, for example, a spring may be disposed on the quick-connect assembly 1, and the quick-connect assembly 1 and the main body 2 are fastened by mechanically pressing, and at this time, the spring abuts against the main body 2, so as to realize axial buffering movement of the ferrule in the quick-connect assembly 1.

In one embodiment, as shown in fig. 3, a second clamping portion 27 is provided on the main body 2 at an end near the first mounting portion 24, the second clamping portion 27 is used for clamping the optical fiber cable 5, and the second clamping portion 27 gradually increases from the end near the second cavity 22 to the end near the first mounting portion 24.

In a specific implementation process, the main body 2 is further provided with a second clamping portion 27, and the first mounting portion 24 is disposed at an end of the second clamping portion 27. In order to tightly connect the main body 2 and the housing 3, the main body 2 is not easy to deviate from the accommodating cavity 33 of the housing 3, the second clamping part 27 can clamp the optical fiber cable 5, when the optical fiber cable 5 passes through the second clamping part 27 and enters the second cavity 22, the second clamping part 27 can play a role of fixing and clamping the optical fiber cable 5, and the diameter of the second clamping part 27 of the main body 2 is set to be gradually increased, namely, the diameter of the clamping part 25 gradually increases from one end close to the second cavity 22 to one end close to the first mounting part 24, and meanwhile, the accommodating cavity 33 presses the second clamping part 27 to further prevent the optical fiber cable 5 from deviating from the second cavity 22.

In the connecting process, the user rotates the fastening piece 4, the connecting part 41 on the fastening piece 4 extrudes the first mounting part 24, so that the first mounting part 24 is subjected to extrusion force along the radial direction, and then the first mounting part 24 can drive the second clamping part 27 on the main body 2 to deform along the radial direction under the action of the extrusion force along the radial direction, so that the fiber cable 5 is extruded continuously even if the second clamping part 27 deforms, and the tensile effect is improved.

In the present embodiment, the second clamping portion 27 is capable of clamping the optical fiber cable 5, reinforcing the fitting between the optical fiber cable 5 and the main body 2.

In one embodiment, as shown in fig. 4, the inner wall of the second clamping portion 27 is provided with a second protruding portion 271. In particular, the structure of the second raised portion 271 may be barbs, protrusions, or other structures capable of increasing the clamping force and/or friction with the fiber optic cable 5.

In a specific implementation, in order to further fit the second clamping portion 27 to the optical fiber cable 5, a second protruding portion 271 is provided on an inner wall of the second clamping portion 27.
