Description

Technical Field

[0001] This utility model relates to the field of optical fiber connector technology, and in particular to an optical fiber connector with a wire clamping structure. Background Technology

[0002] Fiber optic connectors are specialized devices used to connect optical fibers. Their precise design and structure ensure efficient transmission of optical signals, optimize the connection quality and stability of fiber optic communication systems, thereby improving communication performance, data transmission speed, and reducing signal loss rate. They are widely used in telecommunications, network communication, data centers, and other fields.

[0003] A search revealed that patent number "CN213780435U" discloses "a fiber optic connector with a wire clamping structure, comprising an outer shell, a front shell, a rear shell, and a tail sleeve. The outer shell is fitted over the front shell, the rear shell is connected to the rear end of the front shell, and the front end of the tail sleeve is fitted over the rear end of the rear shell. A wire clamping frame is installed at the rear end of the rear shell. Two downward-bent feet are provided on the front and rear outer walls of the wire clamping frame. A wire clamping groove is formed between the two bent feet on the front side and between the two bent feet on the rear side of the wire clamping frame. The width of each wire clamping groove gradually decreases from bottom to top. A wire clamping groove is also provided on the inner wall of the rear shell." Each bending point is provided with a clearance groove, and the bottom of each clearance groove has a through hole for the bending point to pass through. This utility model can effectively prevent the optical fiber from detaching from the optical fiber connector and improve the reliability of the optical fiber connector after connection with the optical fiber. In use, the optical fiber is fixed by the rear sleeve to prevent the optical fiber from falling off and improve reliability. However, in use, the device may damage the optical fiber cut when connecting with the optical fiber, which will affect the connection success rate and signal transmission efficiency. At the same time, the operation of the device is complicated when replacing the optical fiber. It is necessary to press the four bending points separately to remove the optical fiber, which is cumbersome and affects the installation efficiency.

[0004] Therefore, we provide fiber optic connectors with a crimped wire structure to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This fiber optic connector with a wire clamping structure, through the installation mechanism, uses a connecting component to fix and connect the outer sheath of the fiber optic cable, and a fixing component to connect the fiber optic cut. When the fiber optic cable needs to be replaced, pressing the button squeezes the first spring, squeezing out the end of the elastic tube, thereby popping out the elastic tube and the tapered tube, removing the end cap, and taking out the fiber optic cable.

By inserting the contact tube into the end cap, the end cap squeezes the tapered tube, and the elastic tube compresses the second spring, thereby bringing the end of the elastic tube into contact with the button, thus fixing the elastic tube and the tapered tube. At the same time, the optical fiber is guided into the inner side of the elastic tube through the tapered tube, avoiding damage to the front end contact of the optical fiber, which would affect the transmission effect and the success rate of the optical fiber connection. The device has a simple structure, is easy to operate, and facilitates the insertion and replacement of optical fibers. At the same time, it does not damage the optical fiber during installation, thus improving the efficiency of optical fiber replacement and connection. Attached Figure Description

Detailed Implementation

[0021] Please see Figure 1-3 The present invention provides a technical solution: an optical fiber connector with a wire pressing structure, including a plug terminal 1 and an installation mechanism 6. One end of the plug terminal 1 is fixedly connected to a connecting tube 2. Friction strips 3 are provided at both the front and rear ends of the plug terminal 1. The other end of the plug terminal 1 is provided with an end cap 4. The other end of the end cap 4 is fixedly connected to a flexible tube 5. The installation mechanism 6 is provided on the inner side of the plug terminal 1.

[0022] The mounting mechanism 6 includes a connecting component 61 and a fixing component 62. The connecting component 61 is provided on the surface of the end cap 4, and the fixing component 62 is provided on the inner side of the plug terminal 1.

[0023] Furthermore, the connecting component 61 includes a cover plate 611 and a rack 612. The cover plate 611 is rotatably connected to the surface of the end cover 4, and the rack 612 is provided on the inner side of the end cover 4. When the optical fiber is connected, the cover plate 611 is opened, the optical fiber is inserted into the end cover 4, the cover plate 611 is closed, and the optical fiber is fixed by the rack 612.

[0024] Furthermore, the fixing component 62 includes a button 621, a first spring 622, an elastic tube 623, a second spring 624, a tapered tube 625, and a contact tube 626. Buttons 621 are inserted into both the top and bottom of the plug terminal 1. Multiple sets of buttons 621 are provided. A first spring 622 is sleeved on the outer side of the end of each button 621. Two sets of first springs 622 are correspondingly provided for each button 621. An elastic tube 623 is sleeved on the inner side of the connecting tube 2. The inclined surface at the end of the elastic tube 623 corresponds one-to-one with the position of the button 621. A second spring 624 is sleeved on the outer side of the elastic tube 623. One end of the elastic tube 623 is fixedly connected to the tapered tube 625, and the other end of the tapered tube 625 is provided with a contact tube 626. The tube 626 and the contact tube 626 are integrated injection molded with the plug terminal 1. The outer diameter of the contact tube 626 is consistent with the inner diameter of the end cap 4. When connecting the optical fiber, after the optical fiber and the connecting component 61 are fixed, the optical fiber is inserted into the plug terminal 1. The optical fiber is guided through the tapered tube 625 and connected into the elastic tube 623. At this time, the end cap 4 is connected. The end cap 4 pushes the tapered tube 625 and the elastic tube 623 in, and the end bevel of the elastic tube 623 contacts the button 621 to complete the connection. When removing the optical fiber, the first spring 622 is pressed by the button 621, and the elastic tube 623 is pushed out at the same time. Under the action of the second spring 624, the elastic tube 623 and the tapered tube 625 are pushed out.

[0025] Working principle: First, move the fiber optic connector with the crimping structure to the working position. Step 1: Strip and cut the fiber optic sheath to a suitable length. Step 2: When connecting the fiber optic cable, open the cover plate 611, insert the fiber optic cable into the end cover 4, close the cover plate 611, and secure the fiber optic cable using the rack 612. Step 3: Insert the fiber optic cable into the plug terminal 1. The fiber optic cable is guided through the tapered tube 625 and connected to the elastic tube 623. Step 4: Connect the end cover 4. The end cover 4 pushes the tapered tube 625 and the elastic tube 623 in, bringing the beveled end of the elastic tube 623 into contact with the button 621 to complete the connection. Step 4: When replacing the fiber optic cable, press the first spring 622 with the button 621, simultaneously pushing out the elastic tube 623. Under the action of the second spring 624, the elastic tube 623 and the tapered tube 625 are pushed out. This completes the usage process of the fiber optic connector with the crimping structure.
