Description
Technical Field
[0001] The utility model relates to an optical fiber connector, in particular to a plug-in optical fiber connector. Background Art
[0002] An optical fiber is a slender and flexible fiber used to transmit optical signals, usually made of glass or plastic. Optical fiber technology has been widely used in the communication field because it can transmit a large amount of data at a very high speed and has the advantages of low attenuation and electromagnetic interference resistance. It enables light signals to be transmitted between them. An optical fiber connector is a device used to connect two optical fibers or optical cables. Such connectors are very crucial in optical fiber communication systems because they ensure the continuity and quality of optical signals. Optical fiber connectors are usually used in terminal devices, measuring instruments, optical fiber distribution frames, and various types of optical fiber cabling applications.
[0003] The connection method of the optical fiber connector is crucial for ensuring the performance of the optical fiber communication system. However, the existing connection method of the optical fiber connector is a threaded connection to other devices, which may cause the axis to be misaligned during connection, resulting in connection loss, low connection accuracy, and easy generation of gaps at the connection, thereby causing partial loss of optical signals.
[0004] Therefore, it is necessary to design a plug-in optical fiber connector to solve the above technical problems. Summary of the Utility Model
[0005] In order to overcome the defect that the existing connection method of the optical fiber connector is a threaded connection to other devices, which may cause the axis to be misaligned during connection, resulting in connection loss, low connection accuracy, and easy generation of gaps at the connection, thereby causing partial loss of optical signals, the technical problem is: to provide a plug-in optical fiber connector.
[0006] The technical solution of the utility model is: a plug-in optical fiber connector, comprising a housing, a fixed housing, a tail sleeve, an inner white core, a connection block, a ferrule tail handle, a first spring, a plug post, and a dust cap. The fixed housing is slidably connected inside the housing. The tail sleeve is fixedly sleeved at the bottom of the fixed housing. The inner white core is fixedly connected inside the fixed housing. The connection block is fixedly connected inside the inner white core. The ferrule tail handle is slidably connected to the right side inside the connection block. The first spring is connected between the ferrule tail handle and the connection block. The plug post is fixedly sleeved at one end of the ferrule tail handle. The dust cap is slidably placed on one side of the inner white core where the plug post passes through.
[0007] Furthermore, the tail sleeve is made of a soft material.
[0008] Further, it also includes a clamping block and a second spring. The fixing shell is symmetrically provided with the clamping holes on both sides. The inner sides of both sides of the outer shell are symmetrically and slidably connected with the clamping blocks. A second spring is connected between each clamping block and the outer shell. Each clamping block is in clamping fit with the corresponding clamping hole.
[0009] Further, it also includes a base, a bolt and a placement frame. The outer shell is symmetrically and fixedly connected with the bases on one side. The bolts are slidably placed in both bases. The placement frame is fixedly connected between the two bolts.
[0010] Further, the placement frame is made of a transparent material.
[0011] Further, it also includes a baffle. The outer shell is fixedly connected with the baffle on one side.
[0012] The beneficial effects are as follows: 1. The present utility model realizes connection through the insertion action of the insertion post. When the insertion post is inserted, it will push the tail handle of the insertion core to move leftward, so that the first spring is compressed. This design utilizes the elastic force of the first spring to ensure that the insertion post can be firmly held in place, effectively preventing gaps from appearing at the connection between the device and the insertion post. Since the fiber optic connector can be directly inserted into other devices, problems such as connection loss and low connection accuracy caused by misalignment of the axes can be avoided, thus ensuring the stable and reliable performance of the fiber optic communication system.
[0013] 2. Through the cooperation of the clamping block and the second spring, the present utility model ensures the stability when the fixing shell is inserted into the outer shell. This not only facilitates the staff to perform accessory maintenance on the fiber optic connector, but also reduces the frequent plugging and unplugging operations between the insertion post and other devices, thereby reducing the wear degree of the insertion post and prolonging the service life of the fiber optic connector.
[0014] 3. By setting the placement frame, the staff can quickly locate the fiber optic cable that needs to be maintained or replaced, reducing the search time. The design of the placement frame can ensure that each fiber optic cable has a clear position, which is convenient for management and tracking. The orderly layout can avoid problems such as accidental unplugging and misinsertion caused by confusion, reducing the losses caused by operation errors. The maintenance staff can quickly find a specific fiber optic cable according to the label, simplifying the troubleshooting process. The placement frame usually has a labeling system to facilitate the identification of the functions and connection points of each fiber optic cable. The placement frame can effectively protect the fiber optic cable from physical damage, such as excessive bending and extrusion, which helps to prolong the service life of the fiber optic cable.

Specific embodiments
[0021] The following specifically introduces the present utility model in conjunction with the accompanying drawings and specific embodiments.
[0022] Embodiment: A plug-in fiber optic connector, as Figures 1-5 shown, includes an outer shell 1, a fixed shell 2, a tail sleeve 3, an inner white core 4, a connecting block 5, a ferrule tail handle 6, a first spring 7, an insertion post 8, and a dust cap 9. The fixed shell 2 is slidably connected inside the outer shell 1. The tail sleeve 3 is adhesively attached to the bottom of the fixed shell 2. The tail sleeve 3 is made of a soft material. The inner white core 4 is adhesively attached inside the fixed shell 2. The connecting block 5 is adhesively attached inside the inner white core 4. The ferrule tail handle 6 is slidably connected to the right side inside the connecting block 5. A first spring 7 is connected between the ferrule tail handle 6 and the connecting block 5. The right end of the ferrule tail handle 6 is adhesively attached to the insertion post 8. The insertion post 8 passes through the right side of the inner white core 4 and the dust cap 9 is slidably placed thereon.
[0023] As Figure 1 , Figure 4 and Figure 5As shown in the figure, it further includes a clamping block 11, a second spring 12, a base 13, a bolt 14, a placement frame 15 and a baffle 16. The front and rear sides of the fixed shell 2 are symmetrically provided with the clamping holes 10 up and down. The front and rear sides of the inner part of the outer shell 1 are symmetrically and slidably connected with the clamping blocks 11 up and down. A second spring 12 is connected between each clamping block 11 and the outer shell 1. Each clamping block 11 is in clamping fit with the corresponding clamping hole 10. The left side of the outer shell 1 is symmetrically provided with the bases 13 front and rear through screws. The bolts 14 are slidably placed in the two bases 13. The placement frame 15 is adhesively pasted between the two bolts 14. The placement frame 15 is made of transparent material. The baffle 16 is installed on the right side of the outer shell 1 through screws.
[0024] When a fiber optic connector needs to be used, first insert the optical fiber into the ferrule 3, then pass the ferrule 3 with the optical fiber through the fixed housing 2 to ensure good contact between the optical fiber and the inner white core 4. Then insert the entire fixed housing 2 assembly into the outer housing 1 to complete the assembly. When in use, the dust cap 9 can be pulled out to the right. After that, insert the fixed housing 2 into the corresponding interface on other devices. During the insertion process, the insertion post 8 will be squeezed and move to the left, which will cause the ferrule shank 6 to also move to the left and compress the first spring 7, so that the ferrule shank 6 is in close contact with the inserted optical fiber, ensuring good signal connectivity. When the fiber optic connector is pulled out from other devices, the ferrule shank 6 and the insertion post 8 will reset under the action of the first spring 7, and the ferrule shank 6 and the insertion post 8 will move to the right to the original position. To ensure the stability of the fixed housing 2 inserted into the outer housing 1, when the fixed housing 2 is inserted into the outer housing 1, the locking block 11 will be squeezed and move away from the fixed housing 2. At this time, the second spring 12 is compressed. When the fixed housing 2 is completely pushed into the outer housing 1, the locking hole 10 on it will be aligned with the locking block 11. At this time, the locking block 11 will move towards the fixed housing 2 under the elastic force of the second spring 12 and snap into the locking hole 10, thus ensuring that the fixed housing 2 will not easily come out of the outer housing 1. If it is necessary to replace the accessories inside the fixed housing 2, the fixed housing 2 can be pulled out downward from the outer housing 1. During this process, the locking block 11 will be squeezed and move away from the fixed housing 2, and at the same time the second spring 12 is compressed. When the fixed housing 2 is completely pulled out of the outer housing 1, the locking block 11 will reset under the action of the second spring 12 and return to its initial position. Considering that there are many optical fibers inserted in other devices, if it is necessary to search for or repair a single optical fiber, each optical fiber can be marked. The staff can prepare identification cards and insert them into the placement frame 15. Then move the placement frame 15 to the right so that the insertion pin 14 is inserted into the base 13 to fix the placement frame 15 on the outer housing 1. If it is necessary to take out the identification card, just move the placement frame 15 to the left so that the insertion pin 14 is disengaged from the base 13, and the placement frame 15 can be easily taken out. In addition, after the fiber optic connector is inserted into other devices, dust can be prevented by the baffle 16. The baffle 16 can block the connection gap between the fiber optic connector and other devices to prevent dust from entering the gap, thus avoiding affecting the quality of signal transmission.
