Detailed Description

The embodiments of the present invention will be described below with reference to the drawings.

The optical fiber distribution equipment is applied to optical network technology. Optical network technology refers to network fabric technology that uses optical fiber transmission. The optical network technology is not only a simple optical fiber transmission link, but also realizes interconnection and flexible scheduling of a multi-node network by utilizing an optical and electronic control technology on the basis of a large-capacity, long-distance and high-reliability transmission medium provided by optical fibers. Optical networks generally refer to wide area networks, metropolitan area networks, or newly created large area local area networks that use optical fibers as the primary transmission medium.

An Optical Network or an Optical fiber scheduling system provided in an embodiment of the present application is an ODN (Optical Distribution Network). The ODN is a Fiber-To-The-Home (FTTH) cable Network based on a PON (Passive Optical Network) device, and functions To provide an Optical transmission channel between an OLT (Optical Line Terminal) and an ONU (Optical Network Unit). Functionally, an ODN can be divided into four parts, a feeder cable subsystem, a distribution cable subsystem, a service cable subsystem, and an optical fiber termination subsystem, from the local side to the subscriber side.

FIG. 1 illustrates an ODN architecture. Referring to fig. 1, the local side OLT is a feeder cable subsystem, the optical distribution point is a distribution cable subsystem, the optical access point is a subscriber cable subsystem, and the user terminal is an optical fiber terminal subsystem. An optical path is realized between the local side OLT and the optical distribution point through a feeder cable, an optical path is realized between the optical distribution point and the optical access point through a distribution cable, and an optical path is realized between the optical access point and the user terminal through a home cable. Specifically, a feeder cable from an Optical Distribution Frame (ODF) of an Optical Line Terminal (OLT) to an Optical Distribution point serves as a trunk cable to implement long-distance coverage; distribution cables from the optical distribution points to the optical access points are used for the nearby distribution of optical fibers to the subscriber areas along the feeder cable; and the service cable from the optical access point to the user terminal realizes fiber service. In fig. 1, Closure is a cable junction box, FDT is a Fiber Distribution box (Fiber Distribution Terminal), SPL is a splitter, FAT is a Fiber Distribution box, ATB is a Fiber termination box, and ONT is an optical network Terminal. The optical fiber distribution equipment provided by the present application may be an ODF or an FDT provided in the optical network shown in fig. 1 and inside the local side OLT.

Specifically, the ODF is a wiring connection device between an optical network (e.g., a local area network) and an optical communication device or between different optical communication devices. The ODF is used for terminating and distributing local side trunk cables in an optical fiber communication system, and can conveniently realize connection, distribution and scheduling of optical fiber lines. With the increasing integration degree of networks, an Optical Distribution Frame (ODF), a Digital Distribution Frame (DDF), and a power Distribution unit are integrated into a single optical Distribution Frame, and the optical Distribution Frame is suitable for small and medium-sized Distribution systems from optical fibers to cells, from optical fibers to buildings, from remote modules, and from wireless base stations.

The central machine room is the core of the enterprise cable network management system, and the central machine room is in optical communication with each station through the communication product receiving module. Fig. 2A schematically depicts four stations, namely station 1, station 2, station 3, and station 4, and in an actual network deployment process, more stations may be included or only one or two stations may be provided according to specific situations. Each station can be regarded as a substation interaction system, and the architecture of the substation interaction system can be similar to that of the central computer room. Fig. 2A schematically depicts two devices, i.e. device 1 and device 2, and the number of devices can be adjusted according to specific situations during actual network deployment.

As shown in fig. 2A, the central computer room may have optical communication interaction with each station, the central computer room may have optical communication interaction with each device, each station may have optical communication interaction with each device, and each station may have optical communication interaction with each device.

When the connector 60 is positioned in the connector-receiving region 3016, the second opening 6132 of the connector 60 faces the cable-receiving region 3017 so that the cable 63 can extend directly into the cable-receiving region 3017 from outside the passageway between the two positioning faces 164.

The present application removes the connector 60 from the jumper storage device 300 through the plugging device 200. Referring to fig. 17 and 18, the plugging device 200 according to an embodiment includes a lifting rail 27, a swing arm 28, and a connecting head 29, where the swing arm 28 is slidably connected to the lifting rail 27, and the connecting head 29 is fixedly connected to a distal end of the swing arm 28. Through the movement of the swing arm 28 relative to the lifting rail 27, the Z-axis direction movement of the connector 29 can be realized, and through the rotation connection structure between the branches of the swing arm 28, the swing arm 28 can drive the connector 29 to move arbitrarily in the plane where the X-axis and the Y-axis are located. As shown in fig. 18, the connection head 29 of the plugging device 200 includes a plugging body 291 and a mating portion 292, and in one embodiment, the mating portion 292 is fixedly connected to a receiving space of the housing 61 of the connector 60 in a rotating manner, specifically, the mating portion 292 is a screw rod provided with an external thread, and the receiving space is a threaded hole.

The connector 29 is connected to a rotating pair (not shown), and the motor can drive the connector 29 to rotate, so that the connector 29 extends into the accommodating space of the connector 60 and is fixedly connected to the housing 61 of the connector 60 by means of screw-thread fit in a rotating manner.

The process of removing the connector from jumper memory device 300 by plugging device 200 is described as follows.

By adjusting the swing arm 28 of the plugging device 200, the end of the screw of the connecting head 29 of the plugging device 200 is aligned with the third opening 6122 on the rear end face 612 of the connector 60, the connecting head 29 is driven to move along the lifting rail 27, so that the matching portion 292 moves towards the third opening 6122 and moves until the matching portion 292 contacts with the inner wall of the third opening 6122, the starting motor drives the revolute pair to rotate, so that the matching portion 292 rotates, the matching portion 292 moves into the accommodating space 615 through the matching between the matching portion 292 and the internal threads in the accommodating space 615 of the housing 61 of the connector 60 and is fixedly connected with the housing 61, at this moment, the plugging body 291 of the connecting head 29 completely covers the rear end face 612, and the plugging body 291 also covers the pressing surface 6172. Then, the connector 29 moves the connector 60 out of the jumper storage device 300 by the movement of the connector 29 along the lifting rail 27.

Fig. 19-25 illustrate the process of the plugging device 200 inserting one connector 60 into an adapter port on the distribution panel 103.

As shown in fig. 19, the swing arm 28 of the plugging device 200 is adjusted to face the connector 60 to one of the adapter ports from above the wiring panel 103. The bottom of the adapter port has been connected to the opposite connector, in this state, the second opening 6132 of the housing 61 of the connector 60 faces the center of the wiring panel 103, i.e. the outlet direction of the cable 63 of the connector 60 extending from the optical channel in the housing 61 faces the center of the wiring panel 103 (the cable 63 is not drawn in fig. 19), and the pressing surface 6172 of the outer surface of the housing 61 is located on the side of the housing 61 adjacent to the elastic pressing piece 35.

As shown in fig. 20, the connection head 29 of the plugging device 200 moves along the lifting rail 27, so that the connection head 29 carries the connector 60 to move downward (i.e. to move toward the distribution panel 103), and the part of the ferrule 62 of the connector 60 exposed outside the front end surface 611 of the housing 61 moves into the adapter port. At this time, the front end surface 611 of the housing 61 moves to the opening position of the adapter port.

As shown in fig. 21, the connection head 29 and the connector 60 continue to move downward, the housing 61 of the connector 60 partially enters the adapter port, and at this time, the housing 61 contacts the elastic pressing member 35, specifically, in this state, an edge of the third face 6175 of the second section 617 of the housing 61 of the connector 60, which is far from the rear end face 612 (i.e., a boundary edge between the third face 6175 and the inclined face 618) contacts an intermediate position of the abutting portion 3533 of the elastic piece 353 of the elastic pressing member 35.

As shown in fig. 22, the connecting head 29 carries the connector 60 to move downwards continuously, so that the housing 61 of the connector 60 moves along the abutting portion 3533 of the elastic piece 353 of the elastic pressing piece 35, and in this state, the housing 61 of the connector 60 contacts the end position of the abutting portion 3533 of the elastic piece 353. In the process from the state shown in fig. 21 to the state shown in fig. 22, the elastic pressing member 35 is elastically deformed by the pressing of the housing 61, and it can also be understood that the abutting portion 3533 of the elastic piece 353 is pushed by the pushing force of the housing 61 to the inner side surface 363 of the fixing ring 36, and the gap between the abutting portion 3533 of the elastic piece 353 and the inner side surface 363 of the fixing ring 36 is reduced.

As shown in fig. 23, the connecting head 29 carries the connector 60 to move downward continuously so that the connector 60 is inserted into the adapter port completely, and the front end face of the ferrule 62 of the connector 60 is in contact with the ferrule of the opposite connector. In this state, the end of the abutting portion 3533 of the spring 353 of the elastic pressing member 35 is separated from (i.e., not in contact with) the housing 61 of the connector 60, and the end of the abutting portion 3533 of the spring 353 of the elastic pressing member 35 contacts the connecting head 29 of the inserting and extracting device 200.

As shown in fig. 24, the connection head 29 is rotated to move the connection head 29 upward (in this process, the moving speed needs to be controlled, so that the connector 60 is held in the adapter port in a compressed state, that is, in tight contact with the ferrule between the opposite end connectors 60), the partial fitting portion 292 of the connection head 29 moves out of the accommodating space 615 of the connector 60, and a gap is formed between the plug body 291 of the connection head 29 and the rear end 612 of the housing 61 of the connector 60, in this state, due to the existence of the gap, the end of the abutting portion 3533 of the elastic piece 353 of the elastic holding piece 35 moves into the gap under the action of its own elastic force.

As shown in fig. 25, during the upward movement of the connection head 29, the gap between the insertion body 291 of the connection head 29 and the rear end 612 of the housing 61 of the connector 60 gradually increases, and when the connection head 29 leaves the connector 60, the elastic piece 353 of the elastic pressing piece 35 abuts against the pressing surface 6172, so as to lock the connector 60 to the adapter port.

The process of the plugging device removing the connector within the adapter port is seen in fig. 25-19 in reverse order. The specific description is as follows: as shown in fig. 25 and 24, when the connector 60 in the adapter port needs to be taken out, the connection head 29 of the plugging device 200 is moved to above the wiring panel 103 so that the tip of the fitting portion 292 of the connection head 29 is aligned with the third opening 6122 of the rear end surface 612 of the housing 61 of the connector 60. The connection head 29 is moved downward, and when the fitting portion 292 of the connection head 29 contacts the housing 61 at the position of the third opening 6122, the rotating motor of the inserting and extracting device 200 is started, so that the connection head 29 is rotated. In the process of rotating the connector 29, the mating portion 292 is engaged with the thread in the receiving space 615, so that the connector 29 moves downward while rotating, and in the process of moving, the plug body 291 of the connector 29 contacts the abutting portion 3533 of the resilient piece 353 of the resilient pressing member 35 and applies a pushing force to the abutting portion 3533 of the resilient piece 353, so that the resilient piece 353 is drawn toward the inner side 363 of the fixing ring 36. In this process, the end of the abutting portion 3533 of the resilient piece 353 moves on the pressing surface 6172 toward the edge of the pressing surface 6172.

As shown in fig. 23, when the matching portion 292 completely enters the receiving space 615, an end surface of the plug main body 291 of the connecting head 29 contacts the rear end 612 of the housing 61 of the connector 60, at this time, the plug main body 291 completely covers the pressing surface 6172, a tip of the abutting portion 3533 of the resilient piece 353 is located outside the pressing surface 6172, and a tip of the abutting portion 3833 of the resilient piece 353 contacts an outer edge of the plug main body 291. Referring to fig. 22, 21, 20 and 19 in sequence, the plugging device 200 is operated to move the connecting head 29 carrying the connector 60 upward, so that the connector 60 gradually moves out of the adapter port, and the abutting portion 3533 of the elastic piece 353 automatically returns.

This application is pressed through elasticity and is held the piece and insert the in-process elastic deformation of adapter port at the connector and accomplish avoiding the position of insertion process and accomplish the self return of inserted state, realizes the locking, does not need the functional structure of other locks of extra operation or unblock, only need be at the in-process of plug connector, through the pushing away of connector and plug device and elasticity pressure holding, realizes the synchronous locking and the synchronous unblock of plug process. The method has the advantages of easiness in operation and low cost.

Specifically, the wire pressing disk 38 has a disk shape, and the wire pressing disk 38 includes a flat plate-shaped wire pressing body 381, an edge portion 382 located on the outer periphery of the wire pressing body 381, and a fixing portion 383 located at the center of the wire pressing body 381. The fixing portion 383 of the wire pressing disc 38 is used for pressing the connecting jumper wire, so that the connecting jumper wire inserted on the wiring panel is accommodated in the accommodating space between the wire pressing disc and the wiring surface, and a large number of optical fiber cables do not need to be stacked on one side of the wiring panel, which is beneficial to saving the internal space of the optical fiber wiring equipment.

In one embodiment, the outer edge of the pressing line body 381 is rounded, and the pressing line body 381 may be parallel to the wiring surface 33. The edge portion 382 and the line pressing body 381 are of a unitary structure, and the edge portion 382 is turned up from the outer edge of the line pressing body 381 toward a direction away from the wiring surface 33.

The spare patch cord that has been inserted into the adapter port is the connection patch cord. The process of picking and inserting the other connector by the plugging device 200 is as follows.

After the plugging device 200 takes out another connector 60 from the wire taking window W of the jumper storage device 300, the whole spare jumper is pulled out, that is, the cable of the spare jumper is also pulled out of the jumper storage device 300, and the plugging device 200 keeps the middle part of the cable as straight as possible in the process of inserting the connector 60 into the corresponding second port 12. As shown in fig. 26, during insertion of the connector 60 into port a by the plugging device 200, the connector 29 moves directly from the jumper storage device 300 to the a position (along the first trajectory T1). When another connector needs to be inserted into the B port, the connector is first taken out from the jumper storage device 300, the connection head 29 moves the connector to the point C along the second track T2, and then to the point D, and when the point D is reached, the distance between the ADs is nearly the same as the length of the spare jumper.

The jumper storage device 300, the wiring panel 108, the trimming mechanism 43, and the conveying mechanism 42 are disposed at different tooling positions around the plugging device 200, specifically, in the present embodiment, four tooling positions are disposed at the periphery of the plugging device 200, which are respectively a first station T1 for taking out the fiber where the jumper storage device 300 is located, a second station T2 for inserting the fiber where the wiring panel 108 is located, a third station T3 for trimming the fiber where the trimming mechanism 43 is located, and a fourth station T4 for conveying the abandoned jumper where the conveying mechanism 42 is located. In a position between the third station T3 and the fourth station T4, the base plate 106 is provided with a window 1066, the recovery box 41 is below the window 1066, and the window 1066 is located between the third station T3 and the fourth station T4.

Referring to fig. 31, the plugging device 200 is composed of a three-axis driven robot system, and the plugging device 200 includes a base 201, a rotating shaft 202, a robot 203 and a clamping jaw 204. The base 201 is used for bearing and installing all components of the plugging device 200, so that the plugging device 200 forms an integrated modular device, and is convenient to install and replace. The base 201 is fixed to the substrate 106, so as to position and mount the plugging device 200 on the substrate 106. The shaft 202 is fixed to the base 201, one end of the robot arm 203 is rotatably connected to the shaft 202, and the clamping jaw 204 is disposed at the other end (which can be understood as the free end of the robot arm) of the robot arm 203. In one embodiment, the first station T1, the second station T2, the third station T3, and the fourth station T4 are disposed on the same circumference around the rotating shaft. The plugging device 200 comprises three motors, wherein a first motor 205 is mounted on the rotating shaft 202 and used for driving the mechanical arm 203 to rotate around the rotating shaft 202, so that the clamping jaws 204 respectively reach different stations to finish actions of taking fibers, plugging/unplugging connectors, abandoning jumper wires and the like; the second motor 206 is mounted on the base 201 and used for pushing the mechanical arm 203 to move up and down along the Z-axis direction (i.e. to move in a direction perpendicular to the substrate 106) so as to correspondingly pull out and insert the same posture; a third motor 207 is provided adjacent the gripper 204 for performing the gripping/releasing action of the gripper 204 on the fiber.

The wiring is realized by the rotation, lifting and clamping operations of the plugging device 200 and the rotation action of the wiring panel 108. When the fiber distribution equipment has a need to connect a new service port, for example, in a case where an optical path needs to be implemented by connecting a destination port a and a destination port B on the distribution panel 108, the specific operation is as follows.

Referring to fig. 29, 30 and 31, the robot arm of the plugging device is rotated to the first station T1, so that the robot arm 203 first takes out the connector at one end of the spare jumper from the wire-taking window W of the jumper storage device 300, the robot arm 203 is rotated, the clamping jaws 204 of the plugging device 200 clamp the connector and move to the second station T2, the wiring panel 108 is rotated, the target port a on the wiring panel 108 moves to the second station T2, and at this time, the target port a is aligned with the clamping jaws 204, and the connector is inserted into the target port a. The robotic arm 204 then rotates back to the first station T1 so that the gripper 204 removes the connector at the other end of the spare patch cord from the patch cord storage device 300, and manipulates the wiring panel 108 to rotate until the target port B is aligned with the second station T2, wherein during rotation of the wiring panel 108, it is necessary to ensure that the cable of the spare patch cord is routed around the central axis of the wiring panel 108, and the range of rotation of the wiring panel 108 is 180 degrees or greater and 360 degrees or less. The robot arm 204 rotates to the second station T2, the target port B is aligned with the jaw 204, and the plugging action is completed. In this manner, equal length jumpers may be used to complete the connection of the optical paths between the two ports.

Referring to fig. 32-35, a fiber-winding structure 1087 at the location of the central axis 1082 of the distribution panel 108 is used to bypass the connecting patch cord. As shown in fig. 32, in which a plurality of adapter ports are distributed on the same circumference and have a rotationally symmetric structure with a central axis as a center, fig. 32 schematically depicts 12 adapter ports, including 6 first ports 11 and 6 second ports 12, where the 6 first ports are enclosed by a dashed box, which is denoted by 11, and the adapter ports are denoted by first ports, and likewise, the 6 second ports are also enclosed by dashed boxes, which are denoted by 12, and the adapter ports are denoted by second ports. A fiber winding structure 1087 is provided at the location of the central axis 1082. Two connection jumpers L1, L2 are schematically depicted. The rotation of the wiring panel 108 during the wiring process of the two connection jumpers L1 and L2 will be described in detail below. In fig. 32, the rectangular box position represents the second station T2 of the plugging device 200 of the fiber distribution equipment.

When the first optical jumper L1 needs to be wired into the first port a1 and the second port B1, the plugging device 200 inserts one connector of the first optical jumper L1 into the first port a1, and then rotates the wiring panel 108 in the direction of the arrow shown in fig. 32, that is, rotates the wiring panel 108 counterclockwise, where the angle of rotation of the wiring panel 108 is greater than 180 degrees, so that the second port B1 rotates to the second station T2, as shown in fig. 33, during the process of rotating the wiring panel 108, the cable of the first optical jumper L1 bypasses the fiber winding structure 1087, in this state, another connector of the first optical jumper L1 is inserted into the second port B1, completing the wiring of the first optical jumper L1, and during the wiring of the first optical jumper L1, the plugging device operates the first optical jumper L1 to keep the straight state as much as possible. In addition to fig. 33, when the second connection jumper L2 needs to be connected to the first port a2 and the second port B2, the first port a2 needs to be rotated to the second station first, and as shown in fig. 33, the wiring panel may still be rotated counterclockwise, but in this case, the wiring panel may also be rotated clockwise, and only the first port a2 needs to be rotated to the second station T2, which direction may be the same. As shown in fig. 34, at this time, after the first port a2 is rotated to the second station T2, and one connection jumper of the second connection jumper L2 is inserted into the first port a2, the wiring panel needs to be rotated clockwise (in the direction of the arrow shown in fig. 34) until the second port B2 is rotated to the second station T2 (as shown in fig. 35), and likewise, in the process of rotating the wiring panel, the cable of the second connection jumper L2 bypasses the fiber winding structure 1087, and at this time, the other connector of the second connection jumper L2 is inserted into the second port B2, so as to complete the wiring of the second connection jumper L2.

In summary, in the process of wiring by rotating the wiring panel 108 in conjunction with the operation of the plugging device 200, the rotation direction of the wiring panel 1008 is determined according to the positions of the first port 11 and the second port 12 on the circumference, and as long as the rotation angle of the wiring panel 108 is ensured to be greater than or equal to 180 degrees and less than or equal to 360 degrees, the cable of the spare patch cord can bypass the fiber winding structure 1087 at the central axis position of the wiring panel 108 in the rotation process.
