Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber connector technology, specifically to an anti-loosening structure for an optical fiber connector. Background Technology
[0002] Fiber optic connectors are core components in optical communication systems used for the rapid connection of optical fibers to equipment. Their core function is to achieve low-loss, high-stability connections between optical fibers, ensuring efficient transmission of optical signals. The performance of connectors depends critically on insertion loss and return loss, while the end-face polishing method also directly affects signal quality. To ensure long-term reliable operation, connectors need to be cleaned regularly and installed correctly to avoid loosening or contamination that could lead to signal degradation. In the future, with the growth in demand from 5G and data centers, smaller and more intelligent fiber optic connector technology will continue to evolve.
[0003] In practical applications, connector loosening is a common fault. The main causes include mechanical wear, improper installation, environmental factors, and external forces. After loosening, signal attenuation is aggravated, insertion loss increases due to fiber end face misalignment, resulting in a decrease in optical power. Moreover, long-term loosening may cause physical damage, such as end face scratches. In extreme cases, intermittent connection interruptions can also affect network reliability and increase maintenance costs. Utility Model Content
[0004] To address the aforementioned issues, this application provides an anti-loosening structure for fiber optic connectors, resolving the problem of connectors becoming loose after prolonged use.
[0005] An anti-loosening structure for an optical fiber connector includes a connector body, multiple optical fiber sockets mounted on the outside of the connector body, and multiple staggered clearance compartments mounted around the periphery of the connector body.
[0006] The connecting post is slidably installed inside the clearance compartment, and the fiber optic cable is snapped into the end of the connecting post, making the fiber optic cable S-shaped and retaining a pull allowance.
[0007] The stress relief spring is fixedly installed between the connecting column and the relief chamber to absorb the tension on the optical fiber.
[0008] Preferably, a base plate is fixedly installed on the outer side of the connector body, and a top cover is installed on the top of the base plate. Multiple bolt holes are opened on the outer side of both the top cover and the base plate.
[0009] Preferably, the top cover and the bottom plate are each provided with a mounting groove at the end away from the connector body, and a rubber pad is fixedly installed inside the mounting groove.
[0010] Preferably, the clearance chamber is fixedly installed on the inner side of the base plate, and multiple steel balls are rolled and installed at the end of the connecting column.
[0011] Preferably, the end of the connecting column is provided with an anti-detachment hole, and a pin is slidably installed inside the anti-detachment hole.
[0012] Preferably, an elastic rope is fixedly installed at the bottom of the base plate, and a Velcro fastener is fixedly installed at the bottom of the elastic rope. A rubber layer is installed on the side of the Velcro fastener that is attached to the optical fiber.
[0013] The beneficial effects of this utility model are as follows:
[0014] The anti-loosening structure of the fiber optic connector described in this utility model adopts multiple force-relief methods for protection. When the external force pulls the fiber optic cable, the elastic rope is stretched first, which plays a role in force relief and reduces the possibility of external force pulling the fiber optic cable on the inner side of the base plate.
[0015] When the external force increases, the fiber optic cable pulls on the rubber pad, further reducing the possibility of the fiber optic socket being pulled loose.
[0016] As the external force continues to increase, the fiber optic cable inside the base plate is pulled and displaced. Multiple connecting posts enter the clearance chamber, freeing up a certain length of fiber optic cable and thus relieving the force. The relief spring is compressed, which again relieves the force. This multiple protection reduces the possibility of loosening of the fiber optic socket and fiber optic plug connection. Attached Figure Description

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0025] like Figure 1-4 As shown, this utility model embodiment provides an anti-loosening structure for an optical fiber connector, including a connector body 1, a base plate 3 fixedly installed on the outside of the connector body 1, a plurality of optical fiber sockets 2 installed on the outside of the connector body 1, and a plurality of staggered clearance chambers 10 installed around the connector body 1.
[0026] The connecting post 12 is slidably installed inside the clearance chamber 10. The fiber optic cable is snapped into the end of the connecting post 12, so that the fiber optic cable is S-shaped and retains a pulling allowance.
[0027] The unloading spring 11 is fixedly installed between the connecting column 12 and the relief chamber 10 to absorb the tension on the optical fiber.
[0028] In this embodiment, the operator inserts the fiber optic plug into the fiber optic socket 2, and the fiber optic cable is sequentially inserted into the end of the connecting post 12. The fiber optic cable is S-shaped. When the external force is large, the fiber optic cable inside the base plate 3 is pulled and displaced, and multiple connecting posts 12 enter the clearance chamber 10, allowing a certain length of fiber optic cable to be released, which plays a role in relieving force. The force relief spring 11 is compressed, which plays a role in relieving force again. Multiple protections reduce the possibility of loosening of the fiber optic socket 2 and the fiber optic plug connection.
[0029] Specifically, a top cover 4 is installed on the top of the base plate 3. Multiple bolt holes 5 are provided on the outer sides of both the top cover 4 and the base plate 3 for fixing the top cover 4 and the base plate 3 together.
[0030] In this embodiment, the workers connect the top cover 4 and the bottom plate 3 with bolts. The two rubber pads 6 are deformed by the fiber optic cable, which seals the fiber optic socket 2 and plays a role in preventing dust and external damage.
[0031] Specifically, the end of the connecting post 12 is provided with an anti-detachment hole 13, and a pin 14 is slidably installed inside the anti-detachment hole 13 to prevent the optical fiber cable from detaching from the connecting post 12.
[0032] Specifically, the top cover 4 and the bottom plate 3 are both provided with mounting grooves 7 at the ends away from the connector body 1 for threading wires. A rubber pad 6 is fixedly installed inside the mounting groove 7 to seal with the optical fiber cable and fix the optical fiber cable, thereby reducing the possibility of external force pulling and displacing the optical fiber cable inside the bottom plate 3.
[0033] In this embodiment, the optical fiber cable is sequentially inserted into the end of the connecting post 12, and the optical fiber cable is S-shaped. Then, the pin post 14 is inserted into the anti-dislodgement hole 13, and the optical fiber cable is inserted into the rubber pad 6. When pulled by external force, the optical fiber cable pulls the rubber pad 6, further reducing the possibility of the optical fiber socket 2 being pulled loose.
[0034] Specifically, the clearance chamber 10 is fixedly installed on the inner side of the base plate 3, and multiple steel balls 15 are rolled and embedded at the end of the connecting column 12 to reduce the friction between the optical fiber cable and the connecting column 12. When the optical fiber cable inside the base plate 3 is moved by external force, the multiple connecting columns 12 simultaneously make way and relieve the force.
[0035] Specifically, an elastic rope 8 is fixedly installed at the bottom of the base plate 3, and a Velcro 9 is fixedly installed at the bottom of the elastic rope 8. A rubber layer is installed on the side of the Velcro 9 that is attached to the optical fiber cable, so that the Velcro 9 is firmly connected to the optical fiber cable.
[0036] In this embodiment, the worker bends the exposed fiber optic cable of the base plate 3 to leave about 10 centimeters, and then wraps the Velcro 9 around the outside of the fiber optic cable. When the fiber optic cable is pulled by external force, the elastic rope 8 is stretched first, which plays a role in unloading the force and reducing the possibility of external force pulling the fiber optic cable inside the base plate 3.
[0037] Specific working methods:
[0038] The staff inserts the fiber optic plug into the fiber optic socket 2, and then inserts the fiber optic cable into the end of the connecting post 12 in an S-shape. Then, the pin 14 is inserted into the anti-dislodgement hole 13, and the fiber optic cable is inserted into the rubber pad 6. The staff bends the fiber optic cable exposed on the bottom plate 3, leaving about ten centimeters. Then, the Velcro 9 is wrapped around the outside of the fiber optic cable. Finally, the top cover 4 and the bottom plate 3 are connected with bolts. The two rubber pads 6 are deformed by the fiber optic cable, which seals the fiber optic socket 2 and prevents dust and external damage.
[0039] When the optical fiber cable is pulled by external force, the elastic rope 8 is stretched first, which plays a role in unloading the force and reducing the possibility of external force pulling the optical fiber cable inside the base plate 3.
[0040] When the external force increases, the fiber optic cable pulls on the rubber pad 6, further reducing the possibility of the fiber optic socket 2 being pulled loose.
[0041] As the external force continues to increase, the fiber optic cable inside the base plate 3 is pulled and displaced. Multiple connecting posts 12 enter the clearance chamber 10, allowing a certain length of fiber optic cable to be released, thus relieving the force. The relief spring 11 is compressed, which again relieves the force. Multiple protections reduce the possibility of loosening of the fiber optic socket 2 and fiber optic plug connection.
[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
