Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and in particular to an outdoor optical fiber connector. Background Technology

[0002] Because outdoor environments require the transmission of high-bandwidth, long-distance data and often face complex conditions such as wind, rain, temperature differences, and electromagnetic interference, ordinary connection methods cannot meet the requirements for stable transmission. Therefore, outdoor fiber optic connectors are set up to enable the rapid connection and disconnection of outdoor fiber optic lines, ensuring that fiber optic communication systems can continuously and reliably transmit optical signals in outdoor scenarios, and supporting the normal operation of outdoor communication applications such as broadband networks, base station communication, and monitoring systems.

[0003] A search revealed Chinese patent publication number CN207924194U, which discloses an outdoor fiber optic connector, comprising: a female flange assembly, a male connector assembly, a ferrule fixing assembly, and a mating assembly. The mating assembly includes a plug-in component or a threaded locking component. The female flange assembly has mating structures for both the plug-in component and the threaded locking component, allowing for quick plug-in / plug-out installation with the male connector assembly, and threaded locking installation with the male connector assembly via the threaded locking component. Both the female flange assembly and the male connector assembly contain at least one ferrule fixing assembly. This new connector offers multiple mating methods to meet different installation requirements; it is also an ultra-miniature outdoor connector with a compact overall size, stable mechanical performance, meets IP68 waterproof / dustproof rating requirements, and is easy and quick to install.

[0004] The aforementioned patent has the following shortcomings: In actual operation, it is necessary to manually rotate it multiple times to complete the fastening or disassembly. Moreover, in complex working environments such as high altitudes and the field, operators often need to fix the connector with one hand and rotate the parts with the other hand. The operation steps are cumbersome, resulting in a long connection or disconnection process, which is difficult to meet the needs of scenarios with high operational efficiency requirements such as emergency repairs and temporary wiring.

[0005] To address this, an outdoor fiber optic connector is proposed. Utility Model Content

[0014] In some embodiments: the movable plug and the insertion tube form a plugging and unplugging structure; the movable plug and the inner tube form a telescopic structure through a compression spring; the optical fiber is connected to the locking structure and the second pin respectively; and a sealing ring that contacts the insertion tube is fixed on the inner wall of the first connector.

[0015] In some embodiments: the locking bead extends into the interior of the first connector and contacts the inner wall of the locking groove, the cross-section of the locking groove having an arc-shaped structure adapted to the outer surface of the locking bead.

[0016] In some embodiments: the locking beads are evenly distributed on the outer side wall of the first connector, the top end of the return spring abuts against the first connector, and the other end is fixedly connected to the inner wall of the push-pull tube.

[0017] In some embodiments: the fixing structure includes a connecting post fixed to the top end of the first connector and the bottom end of the second connector respectively, a clamping piece fixed to the top end of the connecting post, a rubber sleeve in contact with the clamping piece fixed inside the top end of the connecting post, a threaded sleeve threaded to the outside of the connecting post, and a pressure sleeve fixed to the top end of the threaded sleeve.

Detailed Implementation

[0034] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] Example 1:

[0038] like Figures 1 to 5 As shown, an outdoor fiber optic connector includes a first connector 1, and further includes:

[0039] The inner tube 3 is fixed at the bottom end inside the first connector 1. A movable plug 4 is slidably connected to the outer side of the bottom end of the inner tube 3. A compression spring 2 connected to the first connector 1 is fixed at the top of the movable plug 4. A first pin 5 is installed inside the movable plug 4.

[0040] The insertion tube 12 is inserted and removably connected to the bottom end inside the first connector 1. The bottom end of the insertion tube 12 is fixed with the second connector 10, and the top end inside the second connector 10 is fixed with the second pin 7.

[0041] The optical fiber body 11 is respectively inserted into the second connector 10 and the first connector 1;

[0042] Locking structure 6 is located on the outside of the first connector 1;

[0043] The fixing structure 8 for fixing the optical fiber body 11 is respectively set at the top of the first connector 1 and the bottom of the second connector 10.

[0044] The positioning structure 9 for fixing the position of the device is provided on one side of the first connector 1.

[0045] The movable plug 4 and the insertion tube 12 form a plug-in structure. The movable plug 4 and the inner tube 3 form a telescopic structure through the compression spring 2. The optical fiber body 11 is connected to the locking structure 6 and the second pin 7 respectively. A sealing ring 13 that contacts the insertion tube 12 is fixed on the inner side wall of the first connector 1.

[0046] In this embodiment, when an outdoor fiber optic connection needs to be established, the fiber optic cable 11 is inserted into the first connector 1 and the second connector 10 respectively, while ensuring that the fiber optic cable 11 is precisely aligned with the first pin 5 and the second pin 7. Then, the second connector 10 is pushed to drive the insertion tube 12 into the first connector 1. During the insertion process, the insertion tube 12 will contact the movable plug 4 and push it to move. The movement of the movable plug 4 compresses the compression spring 2, allowing the compression spring 2 to store elastic potential energy, providing reset power for subsequent disconnection. At the same time, the compression spring 2 generates a reverse elastic force acting on the movable plug 4, making the first pin 5 and the second pin 7 fit tightly together, avoiding signal transmission loss due to gaps between them. The sealing ring 13 is in close contact with the outer wall of the insertion tube 12, thereby achieving a seal between the insertion tube 12 and the first connector 1, which to a certain extent prevents external moisture and dust from entering the connector and affecting optical signal transmission.

[0047] like Figures 1 to 4 As shown, the locking structure 6 includes a push-pull tube 602 slidably connected to the outside of the first connector 1. A movable groove 601 is provided on the inner side wall of the push-pull tube 602. A locking bead 603 is rotatably connected to the outer side wall of the first connector 1. A locking groove 605 is provided on the outer side wall of the insertion tube 12. A return spring 604 connected to the first connector 1 is fixed at the top end inside the push-pull tube 602. The locking bead 603 extends into the interior of the first connector 1 and contacts the inner wall of the locking groove 605. The cross-section of the locking groove 605 is an arc-shaped structure adapted to the outer surface of the locking bead 603. The locking beads 603 are evenly distributed on the outer side wall of the first connector 1. The top end of the return spring 604 abuts against the first connector 1, and the other end is fixedly connected to the inner wall of the push-pull tube 602.

[0048] In this embodiment, when the insertion tube 12 is inserted into the first connector 1, the push-pull tube 602 is pulled upward to align the movable groove 601 with the locking bead 603. At this time, the insertion tube 12 can be inserted into the interior of the first connector 1. Then, the push-pull tube 602 is released. Under the action of the return spring 604, the movable groove 601 and the locking bead 603 are misaligned. The inner wall of the push-pull tube 602 abuts against the locking bead 603 and embeds it into the locking groove 605, fixing the insertion tube 12 inside the first connector 1. If it is necessary to disconnect, the push-pull tube 602 is pulled upward to allow the locking bead 603 to move into the movable groove 601, thereby releasing the lock on the insertion tube 12. At this time, the compression spring 2 releases its elastic potential energy to push the movable plug 4 to reset, causing the insertion tube 12 to disengage from the first connector 1. This achieves rapid locking and unlocking of the connector to a certain extent, improving the efficiency of outdoor operation.

[0049] Example 2:

[0050] An outdoor fiber optic connector, this embodiment is based on embodiment 1 with the following improvements, such as... Figures 1 to 4As shown, the fixing structure 8 includes a connecting post 804 fixed to the top of the first connector 1 and the bottom of the second connector 10 respectively. A clamping piece 803 is fixed to the top of the connecting post 804. A rubber sleeve 805 in contact with the clamping piece 803 is fixed inside the top of the connecting post 804. A threaded sleeve 802 is threaded to the outside of the connecting post 804. A pressure sleeve 801 is fixed to the top of the threaded sleeve 802. The front cross-section of the pressure sleeve 801 is a funnel-shaped inclined structure. The clamping pieces 803 are arranged in a ring at equal intervals at the top of the connecting post 804.

[0051] In this embodiment, after the optical fiber 11 is inserted into the first connector 1 and the second connector 10, the screw sleeve 802 is rotated to move the pressure sleeve 801 toward the clamping plate 803. The funnel-shaped inclined structure of the pressure sleeve 801 exerts a squeezing force on the clamping plate 803, causing the clamping plate 803 to push the rubber sleeve 805 to fit tightly against the outer wall of the optical fiber 11, thereby fixing the optical fiber 11 inside the connecting post 804. This prevents the optical fiber 11 from shifting under external pulling or vibration, and to a certain extent ensures the stable connection between the optical fiber 11 and the first ferrule 5 and the second ferrule 7, reducing signal transmission loss.

[0052] like Figures 1 to 4 As shown, the positioning structure 9 includes limiting grooves 901 respectively opened on the outer side walls of the first connector 1 and the second connector 10. A fixing frame 903 is sleeved on the outer side of the limiting groove 901. An mounting piece 902 is fixed on one side of the fixing frame 903. A flipping frame 905 is rotatably connected to the bottom end of the fixing frame 903. A torsion spring 904 connected to the fixing frame 903 is fixed on the outer side of the rotation shaft of the flipping frame 905. Two sets of fixing frames 903 are provided, and the two sets of fixing frames 903 are symmetrically distributed on the horizontal center line of the mounting piece 902.

[0053] In this embodiment, when it is necessary to fix the connector to the surface of an outdoor object, a nail is used to pass through the pre-drilled hole on the surface of the mounting plate 902 to fix the mounting plate 902 to the surface of the object. Then, the flip frame 905 is pulled to rotate, opening the fixing frame 903. At the same time, the torsion spring 904 is deformed by force, placing the first connector 1 and the second connector 10 between the flip frame 905 and the fixing frame 903, and aligning the flip frame 905 with the fixing frame 903 and the limiting groove 901. The torsion spring 904 pushes the flip frame 905 to fit against the inner wall of the limiting groove 901, preventing the fixing frame 903 from disengaging from the limiting groove 901, thus fixing the position of the connector.

[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
