Description

Technical Field

[0001] This utility model relates to the field of optical fiber connection technology, and more specifically to an optical fiber connector connection device. Background Technology

[0002] Fiber optic connectors are devices that detachably connect optical fibers. They precisely align the two end faces of the fibers to maximize the coupling of light energy from the transmitting fiber to the receiving fiber, and to minimize the impact on the system caused by their intervention in the optical link. These are the basic requirements of fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems.

[0003] A search revealed a patent publication (CN221631728U) that discloses an optical fiber connector connection device. During use, by installing the mating shells, the guide sleeve of the first optical fiber connector and the guide core of the second optical fiber are aligned. The two mating shells are then secured at the connector positions of the first and second optical fibers. Limiting plates on two support rings are inserted into adjacent mating shells. A spring, in conjunction with a circular plate, drives a T-shaped rod to insert into the adjacent limiting plate, improving the connection strength of the optical fibers, providing an anti-detachment structure, and facilitating use. However, the inventors discovered the following problem in the development of this invention: the aforementioned connection device lacks a structure for pulling and buffering the optical fibers during connection. This makes it prone to misalignment and breakage at the fiber connection point when the optical fiber is subjected to external pulling, affecting the continuity and reliability of the optical transmission system.

[0004] In view of this, the present invention proposes an optical fiber connector connection device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an optical fiber connector connection device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an optical fiber connector connection device, including a first optical cable, a second optical cable, and a connector for connecting the first optical cable and the second optical cable. The first optical cable is provided with a connector head at its end, and the second optical cable is provided with a connector seat at its end. The connector head and the connector seat are mutually compatible, and the top of the connector is provided with a connecting groove for the connector head and the connector seat to be inserted. When the connector head and the connector seat are adapted and inserted into the connecting groove, the positions of the first optical cable and the second optical cable correspond. The connector is provided with a tension buffer component corresponding to the first optical cable and the second optical cable.

[0007] The tension buffer assembly includes two buffer grooves symmetrically opened at the left and right ends of the bottom side of the connector. The front and rear inner walls of the two buffer grooves are provided with limit slide grooves. Limit slide seats are slidably connected inside the limit slide grooves. Support springs that drive the limit slide seats to move towards the center of the connector are fixedly installed on the inner left and inner right walls of the buffer grooves. Guide wheels are rotatably connected to the surface of the limit slide seats. The first optical cable and the second optical cable are respectively wound around the surface of the two guide wheels. The left and right ends of the connector are respectively provided with notches for the first optical cable and the second optical cable to pass through.

[0008] Furthermore, the connector has a longitudinally extending expansion groove on its surface, and a positioning pin is slidably connected inside the expansion groove. The positioning pin extends into the interior of the connection groove. Both the connector head and the connector seat have pin holes on their surfaces. The positioning pin and the pin holes are positioned correspondingly. The inner wall of the expansion groove is provided with a return spring that drives the positioning pin to engage with the pin hole.

[0009] As a further description of the above technical solution: by setting a positioning pin and a pin hole, after the connector head and connector seat are inserted into the connecting groove, the positioning pin is driven into the pin hole by the return spring, which can achieve the purpose of positioning the connector head and connector seat.

[0010] Furthermore, ejector springs are fixedly installed on the inner bottom walls of both connecting slots of the connector, and ejector plates are fixedly installed on the top of the ejector springs. The upper surface of the ejector plates abuts against the bottom ends of the connector head and the connector seat, respectively.

[0011] As a further description of the above technical solution: by setting an ejector spring and an ejector plate, the connector and connector seat can be continuously pushed upward. When the positioning pin is pressed to cancel the braking effect on the connector and connector seat, the elastic force of the ejector spring can be used to push the connector and connector seat upward.

[0012] Furthermore, the connector has a tightening screw threaded on its front side, and a rubber clamp is rotatably connected to the threaded end of the tightening screw. The rubber clamp abuts against the surfaces of the first optical cable and the second optical cable respectively.

[0013] As a further description of the above technical solution: by setting a clamping screw and a rubber clamp, the first optical cable and the second optical cable can be clamped, thereby further improving the tightness of the installation of the first optical cable and the second optical cable.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Compared with the prior art, this fiber optic connector connection device lays the first and second optical cables on the connector surface, then installs the connector head and connector seat with the first and second optical cables respectively, and then fits the connector head and connector seat into the connection groove to complete the connection of the first and second optical cables. During use, by setting a tension buffer component, when the first and second optical cables are subjected to external tension, the limit slide seat drives the guide wheel to slide inside the limit slide groove under the elastic action of the support spring, thus providing tension buffer for the first and second optical cables, avoiding misalignment and breakage at the optical fiber connection point, and improving the continuity and reliability of the optical transmission system.

[0016] 2. Compared with the prior art, this fiber optic connector connection device, by setting a positioning pin and a pin hole, after the connector head and connector seat are inserted into the connection groove, uses a return spring to drive the positioning pin into the pin hole, which can achieve the purpose of positioning the connector head and connector seat; by setting an ejection spring and an ejection plate, the connector head and connector seat can be continuously pushed upward; when the positioning pin is pressed to release the braking effect on the connector head and connector seat, the elastic force of the ejection spring can push the connector head and connector seat upward; by setting a clamping screw and a rubber clamp, the first optical cable and the second optical cable can be clamped, further improving the tightness of the installation of the first optical cable and the second optical cable.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The optical fiber connector connection device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1 to 5 This utility model provides an optical fiber connector connection device, including a first optical cable 2, a second optical cable 3, and a connector 1 for connecting the first optical cable 2 and the second optical cable 3. The first optical cable 2 is provided with a connector head 4 at its end, and the second optical cable 3 is provided with a connector seat 5 at its end. The connector head 4 and the connector seat 5 are mutually compatible, and the top of the connector 1 is provided with a connecting groove 6 for the connector head 4 and the connector seat 5 to be inserted. When the connector head 4 and the connector seat 5 are adapted and inserted into the connecting groove 6, the positions of the first optical cable 2 and the second optical cable 3 correspond.

[0025] The surface of connector 1 has a longitudinally formed telescopic groove 15. A positioning pin 12 is slidably connected inside the telescopic groove 15. The positioning pin 12 extends into the interior of the connecting groove 6. The surfaces of connector head 4 and connector seat 5 are both provided with pin holes 13. The positions of the positioning pin 12 and the pin holes 13 are corresponding.

[0026] The inner wall of the telescopic groove 15 is provided with a return spring 14 that is engaged with the drive positioning pin 12 and the pin hole 13.

[0027] By using the positioning pin 12 and the pin hole 13, after the connector 4 and the connector 5 are inserted into the connecting groove 6, the positioning pin 12 is driven into the pin hole 13 by the return spring 14, which can achieve the purpose of positioning the connector 4 and the connector 5.

[0028] The fiber optic connector connection device lays the first optical cable 2 and the second optical cable 3 on the surface of the connector 1 beforehand, then installs the connector 4 and the connector 5 with the first optical cable 2 and the second optical cable 3 respectively, and then fits the connector 4 and the connector 5 into the connection groove 6 to complete the connection action of the first optical cable 2 and the second optical cable 3.

[0029] The connector 1 is fixedly installed with ejector springs 16 on the inner bottom wall of both connecting slots 6. The top of the ejector springs 16 is fixedly installed with ejector plates 17. The upper surface of the ejector plates 17 abuts against the bottom of the connector head 4 and the connector seat 5 respectively.

[0030] The ejector spring 16 and ejector plate 17 can continuously push the connector 4 and connector 5 upward. When the positioning pin 12 is pressed to cancel the braking effect on the connector 4 and connector 5, the elastic force of the ejector spring 16 can be used to push the connector 4 and connector 5 upward, so as to achieve the purpose of quickly disassembling and disconnecting the connector 4 and connector 5.

[0031] The connector 1 has a threaded connection to a clamping screw 18 on its front side. The threaded end of the clamping screw 18 is rotatably connected to a rubber clamp 19, which abuts against the surfaces of the first optical cable 2 and the second optical cable 3 respectively.

[0032] By tightening the screw 18 and the rubber clamp 19, the first optical cable 2 and the second optical cable 3 can be clamped, thereby further improving the tightness of the installation of the first optical cable 2 and the second optical cable 3.

[0033] Connector 1 is equipped with a tension buffer component corresponding to the first optical cable 2 and the second optical cable 3.

[0034] The tension buffer assembly includes two buffer grooves 7 symmetrically opened at the left and right ends of the bottom side of the connector 1. The front and rear inner walls of the two buffer grooves 7 are provided with limit slide grooves 8. The inside of the limit slide grooves 8 is slidably connected to the limit slide seat 9. The inner left and inner right walls of the buffer grooves 7 are fixedly installed with support springs 10 that drive the limit slide seat 9 to move towards the center of the connector 1. The surface of the limit slide seat 9 is rotatably connected to the guide wheel 11. The first optical cable 2 and the second optical cable 3 are respectively wound around the surface of the two guide wheels 11. The left and right ends of the connector 1 are respectively provided with notches for the first optical cable 2 and the second optical cable 3 to pass through.

[0035] It is worth noting that during the use of the overall connection device, when the first optical cable 2 and the second optical cable 3 are subjected to external pulling action through the traction buffer assembly, under the elastic action of the support spring 10, the limiting slide 9 drives the guide wheel 11 to slide inside the limiting slide groove 8, thereby pulling and buffering the first optical cable 2 and the second optical cable 3, avoiding misalignment and breakage at the optical fiber connection point, and improving the continuity and reliability of the optical transmission system.

[0036] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
