[0002] In the field of modern communications, optical cables are an important signal transmission medium, and the stability and reliability of their connections are crucial to ensuring communication quality. However, in existing technologies, the connection structure of optical cables has some problems, which limit their performance and application.

[0003] However, existing optical cables have some shortcomings that need improvement. Existing optical cable connections may not be secure enough. Over extended use or when affected by external factors, connections can become loose or fall off, leading to interrupted or unstable signal transmission. Some optical cable connection structures lack effective positioning measures, making precise alignment difficult and compromising optical signal transmission quality.

[0004] Existing optical cable connections often lack sealing performance, failing to effectively prevent external factors such as moisture and dust from entering the cable interior. This can easily damage the cable core and optical fibers, shortening the cable's service life. Conventional fiber hole designs may not meet the growing demand for high-speed data transmission, limiting the cable's transmission capacity. Due to issues such as loose connections and poor sealing, optical cables are prone to failure during use, increasing security risks to communication systems and affecting the stability and reliability of communications. Therefore, we have addressed this issue by proposing an optical cable with a locking connection structure. Utility Model Content

Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0029] Example 1: Please refer to Figure 1-Figure 7An optical cable with a connection and locking structure includes an optical cable line 1, an optical cable core 2 is arranged in the optical cable line 1, a connection and fastening ring 3 is arranged at the end of the optical cable line 1, the connection and fastening ring 3 is connected to the optical cable connector 4, an optical cable connection pin 401 is arranged in the optical cable connector 4, a U-shaped positioning hole 402 is opened on the optical cable connection pin 401, an optical cable fiber hole 5 is opened on the optical cable connection pin 401, and a connection and locking ring sleeve 6 is provided on the outer surface of the optical cable connection pin 401.

[0030] The connecting fastening ring 3 is provided with a screw sleeve 302, in which a screw 301 is provided. The screw 301 matches the screw hole 303. The inner surface of the connecting locking ring sleeve 6 is provided with a locking sleeve internal thread 601, and the outer surface of the connecting locking ring sleeve 6 is provided with a locking sleeve anti-slip pattern 602.

[0031] The upper end of the connecting locking ring sleeve 6 is provided with a limit screw 7, which is fastened to the optical cable connector 4. A sealing rubber ring 8 is provided between the connecting fastening ring 3 and the optical cable 1.

[0032] A crimping ring 9 is provided at the base of the optical cable connector 4. The outer diameter of the optical cable connector 4 is 12mm-18mm, and the outer diameter of the optical cable connection pin 401 is 6mm-10mm. There are eight optical fiber holes 5 evenly distributed in a ring.

[0033] The working principle of the optical cable with a connection and locking structure: Optical cable 1 and optical cable core 2: The optical cable core 2 within optical cable 1 transmits optical signals and is the core component of the optical cable's communication function. Connecting fastening ring 3: Located at the end of optical cable 1, it is initially connected to optical cable connector 4 via screw sleeve 302 and screw 301. Screw 301 engages screw hole 303 to secure connecting fastening ring 3 to optical cable connector 4, providing a preliminary fixation between optical cable 1 and connector.

[0034] The optical cable connection pin 401 is set in the optical cable connector 4, and the U-shaped positioning hole 402 is used to assist positioning to ensure the accuracy of the connection. The optical fiber hole 5 is used to accommodate the optical fiber in the optical cable line 1 to achieve the transmission of optical signals.

[0035] Connector locking ring 6: The inner threads 601 of the locking ring mate with the threads on the outer surface of the cable connector post 401. Rotating the locking ring 6 secures it to the cable connector post 401, further enhancing the stability of the connection. Anti-slip grooves 602 on the outer surface of the locking ring facilitate gripping and rotation during operation.

[0036] Limit screw 7: It is set at the upper end of the connection locking ring 6 and fastened to the optical cable connector 4 to limit the position of the connection locking ring 6 to prevent it from excessive rotation or loosening.

[0037] Sealing rubber ring 8: Located between the connecting fastening ring 3 and the optical cable 1, it provides a waterproof seal, protecting the optical fibers inside the cable from environmental influences. Crimping ring 9: Located at the base of the optical cable connector 4, it strengthens the connection and ensures the reliability of the optical cable connection. Optical fiber holes 5: There are eight evenly distributed in a ring, which can accommodate multiple optical fibers simultaneously, increasing the transmission capacity of the optical cable.

[0038] The end of the optical cable 1 is initially secured to the optical cable connector 4 using the screws 301 on the connecting fastening ring 3. Then, the optical cable connector pin 401 is inserted into the corresponding position and accurately aligned using the U-shaped positioning hole 402. Next, the connecting locking ring 6 is rotated so that it is tightened onto the optical cable connector pin 401 via the internal thread, while the limit screw 7 limits the position of the connecting locking ring 6. In this way, a secure connection and locking is achieved between the optical cable 1 and the optical cable connector 4. The sealing rubber ring 8 and crimping ring 9 ensure the sealing and reliability of the connection, ensuring that the optical signal can be stably transmitted in the optical cable.

[0039] The specific working process of the optical cable with a connecting and locking structure is as follows: First, prepare the optical cable 1 and the optical cable connector 4 to be connected. Pass the optical cable core 2 inside the optical cable 1 through the connecting and fastening ring 3, and ensure that the end of the optical cable 1 is tightly fitted with the connecting and fastening ring 3. Install a sealing rubber ring 8 in the gap between the connecting and fastening ring 3 and the optical cable 1 to enhance the seal and prevent the ingress of moisture and dust.

[0040] Align the optical cable connection pin 401 in the optical cable connector 4 with the connection fastening ring 3, and insert the optical cable connection pin 401 into the connection fastening ring 3. At this time, pay attention to the U-shaped positioning hole 402 on the optical cable connection pin 401 to ensure that it is in the correct position for accurate positioning.

[0041] Insert the screw 301 from the screw sleeve 302 on the connecting fastening ring 3 so that it matches the screw hole 303 on the optical cable connector 4. Tighten the screw 301 to preliminarily fix the connecting fastening ring 3 and the optical cable connector 4 together. Pass the optical fiber in the optical cable 1 through the optical cable fiber hole 5 on the optical cable connecting plug 401. Since there are eight optical cable fiber holes 5 evenly distributed in a ring shape, multiple optical fibers can be accommodated at the same time, which improves the transmission capacity of the optical cable. Hold the connecting locking ring sleeve 6. Since its outer surface is provided with a locking sleeve anti-slip groove 602, it is easy to operate. Put the connecting locking ring sleeve 6 on the outer surface of the optical cable connecting plug 401, and screw it together with the outer thread on the optical cable connecting plug 401 through the inner thread 601 of the locking sleeve on the inner surface.

[0042] The connection locking ring sleeve 6 is rotated clockwise to gradually tighten it on the optical cable connection pin 401. During the rotation process, the connection locking ring sleeve 6 will continuously press the connection fastening ring 3 and the optical cable connector 4 to enhance the stability of the connection.

[0043] After the connector locking ring 6 is rotated to the desired position, its upper end is secured to the optical cable connector 4 using a set screw 7. This set screw 7 prevents the connector locking ring 6 from loosening or excessive rotation during use. Finally, a crimping ring 9 is installed at the base of the optical cable connector 4 to further strengthen the connection and ensure the reliability of the optical cable connection.

[0044] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
