Description

Technical Field

[0001] This invention relates to the field of optoelectronic composite cables, specifically a flexible and break-resistant optoelectronic composite cable. Background Technology

[0002] With the booming development of the communications industry, telephone services in communications networks are showing a steady growth trend, while data services are showing an exponential growth trend. Multimedia such as voice, data, and images all need to be transmitted, so a larger network capacity and wider bandwidth are required. Optical fiber composite cables are suitable for use as transmission lines in broadband access network systems. They are a new type of access method that integrates optical fiber and copper power transmission wires, and can solve the problems of broadband access, equipment power consumption, and signal transmission.

[0003] However, when optical fiber composite cables are installed, they are exposed to the external environment. Under such conditions, the cables are subjected to various external pressures. When the external pressure crushes the cable, it can cause the cable to deform and become damaged. In severe cases, the crushing pressure can even cause the cable to break at the crushed location, affecting signal transmission and creating safety hazards.

[0004] Therefore, it is necessary to provide a flexible, break-resistant optoelectronic composite cable to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a flexible and break-resistant optoelectronic composite cable to solve the problem in the background technology that external pressure can cause the cable to deform or even break, affecting signal transmission and creating safety hazards. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flexible and break-resistant optoelectronic composite cable, comprising a reinforcing core, wherein plug slots are equidistantly connected to the outer wall of the reinforcing core, a buffer pad is provided inside the plug slot, and a buffer block extending to the outside of the plug slot is movably connected inside the plug slot, a rubber sleeve is connected to one end of the outer side of the buffer block, a buffer sleeve is provided outside the rubber sleeve, and circular holes are equidistantly opened inside the buffer sleeve, wherein a cable conductor is provided inside the circular holes.

[0007] Preferably, the outer circumferential surface of the buffer sleeve is provided with through slots at equal intervals, and springs are connected to the upper and lower ends of the inner sides of the through slots, and the other end of the springs is connected to a semi-circular ring plate.

[0008] Preferably, the inner wall of the semicircular ring plate is connected with a friction plate, and two sets of the semicircular ring plates can be spliced ​​together to form a circular through hole.

[0009] Preferably, the diameter of the circular through hole near the rubber sleeve is smaller than that of the other set of circular through holes, and a buffer rod is installed inside the circular through hole.

[0010] Preferably, the diameter of the buffer rod gradually decreases from top to bottom and abuts against the outer wall of the rubber sleeve.

[0011] Preferably, the outer wall of the buffer sleeve is sequentially extruded with an inner protective layer, a shielding layer, a waterproof layer, and an outer protective layer.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when the rolling pressure is small, the pressure will squeeze the outer protective layer and thus squeeze the buffer rod at the corresponding position. At this time, the buffer rod moves towards the rubber sleeve. During the movement of the buffer rod, the friction plate first rubs against the buffer rod, and the upward sliding friction force consumes the rolling pressure on the buffer rod, thereby offsetting part of the rolling pressure. 2. In this invention, since the diameter of the buffer rod gradually decreases from top to bottom, and the diameter of the circular through hole near the rubber sleeve is smaller than that of another set of circular through holes, the friction force generated between the friction plate and the buffer rod during the movement of the buffer rod gradually increases with the degree of compression of the spring, and its effect of consuming the squeezing force gradually increases. By setting the buffer rod to abut against the outer wall of the rubber sleeve, the elasticity of the rubber sleeve can further offset the squeezing force on the buffer rod. 3. In this invention, when subjected to a large rolling pressure, the buffer rod will eventually abut against the outer wall of the rubber layer. At this time, the rolling pressure will squeeze the buffer layer and thus squeeze the rubber layer. After the rubber layer is squeezed, it will drive the buffer block to move towards the reinforcing core. At this time, the buffer pad set inside the insertion slot will absorb the rolling pressure. After the rolling is finished, the buffer pad will restore and reset the buffer block. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0017] Please see Figure 1-4 A flexible, break-resistant optoelectronic composite cable includes a reinforcing core 1. Insertion slots 2 are equidistantly connected to the outer wall of the reinforcing core 1. A buffer pad 3 is disposed inside the insertion slots 2. A buffer block 4 extending to the outside of the insertion slots 2 is movably connected inside the insertion slots 2. A rubber sleeve 5 is connected to one end of the outer side of the buffer block 4. A buffer sleeve 6 is disposed outside the rubber sleeve 5. Circular holes 7 are equidistantly arranged inside the buffer sleeve 6. A cable conductor 8 is disposed inside the circular holes 7. When the rubber sleeve 5 is compressed, the compressed position will cause the corresponding buffer block 4 to move towards the reinforcing core 1. During the movement of the buffer block 4, it will compress the buffer pad 3 inside the insertion slots 2 to absorb the compressive force and protect the cable.

[0018] like Figure 1-4 As shown, the outer circumference of the buffer sleeve 6 is provided with through slots 9 at equal intervals. The upper and lower ends of the two sides inside the through slots 9 are connected to springs 10. The other end of the springs 10 is connected to a semi-circular ring plate 11. The buffer rod 13 can be locked and fixed by splicing the opposite semi-circular ring plates 11.

[0019] like Figure 1-4 As shown, the inner wall of the semi-circular ring plate 11 is connected with a friction plate 12. The two sets of semi-circular ring plates 11 can be spliced ​​to form a circular through hole. The two sets of semi-circular ring plates 11 spliced ​​to form a circular through hole fix the buffer rod 13. When the outside of the cable is squeezed, if the squeezing force is small, the buffer rod 13 will be squeezed to move towards the rubber sleeve 5. During the movement of the buffer rod 13, the friction between the buffer rod 13 and the friction plate 12 first consumes the squeezing force on the buffer rod 13.

[0020] like Figure 1-4 As shown, the diameter of the circular through hole near the rubber sleeve 5 is smaller than that of another set of circular through holes. A buffer rod 13 is installed inside the circular through hole. By setting the diameter of the circular through hole near the rubber sleeve 5 to be smaller than that of another set of circular through holes, the friction force generated between the friction plate 12 and the buffer rod 13 gradually increases during the movement of the buffer rod 13, and its effect of consuming the squeezing pressure gradually increases.

[0021] like Figure 1-4 As shown, the diameter of the buffer rod 13 gradually decreases from top to bottom and abuts against the outer wall of the rubber sleeve 5. The buffer rod 13 abuts against the outer wall of the rubber sleeve 5, and the elasticity of the rubber sleeve 5 can further offset the compressive force on the buffer rod 13.

[0022] like Figure 1-4 As shown, the outer wall of the buffer sleeve 6 is sequentially extruded with an inner protective layer 14, a shielding layer 15, a waterproof layer 16, and an outer protective layer 17. The inner protective layer 14, shielding layer 15, waterproof layer 16, and outer protective layer 17 give the cable excellent performance. These are all existing technologies and will not be described in detail.

[0023] Working principle: During use, when the cable is subjected to crushing, if the crushing force is relatively small, the pressure will squeeze the outer protective layer 17, thereby squeezing the corresponding buffer rod 13. At this time, the buffer rod 13 moves towards the rubber sleeve 5. During the movement of the buffer rod 13, the friction plate 12 first rubs against the buffer rod 13, generating an upward sliding friction force to consume the crushing force on the buffer rod 13, thus offsetting part of the crushing force. Since the diameter of the buffer rod 13 gradually decreases from top to bottom, the diameter of the circular through hole near the rubber sleeve 5 is smaller than that of the other set of circular through holes, which allows the buffer rod 13 to move more smoothly. During the process, the friction force generated by the friction plate 12 and the buffer rod 13 gradually increases as the compression of the spring 10 increases, and its effect of consuming the squeezing force gradually increases. The buffer rod 13 is set to abut against the outer wall of the rubber sleeve 5, and the elasticity of the rubber sleeve 5 can further offset the squeezing force on the buffer rod 13. When the crushing force is large, the rubber sleeve 5 is squeezed, and the squeezed position of the rubber sleeve 5 will drive the corresponding buffer block 4 to move towards the reinforcing core 1. During the movement of the buffer block 4, it will squeeze the buffer pad 3 inside the plug groove block 2 to absorb the squeezing force and protect the cable.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
