[0001] This utility model relates to the field of optical composite cable technology, specifically to a fast-connecting optical composite cable. Background Technology

[0002] Optical composite cable (optical-electric composite cable) is a new type of cable that integrates optical fiber and copper power transmission wire into one, and can transmit optical signals and electrical signals simultaneously, solving problems such as broadband access, equipment power supply and signal transmission;

[0003] The "Optical-Electronic Composite Cable" disclosed in announcement number "CN218414077U" includes a cable core, an armor layer, and an outer sheath arranged sequentially from the inside out. The cable core includes multiple optical-electric units arranged sequentially along the circumference of the optical-electric composite cable. Each optical-electric unit includes a sleeve and multiple conductive optical fibers disposed within the sleeve. Each conductive optical fiber includes an optical fiber and a conductive layer arranged sequentially from the inside out. The optical-electric composite cable also includes fillers, with fillers provided in the gaps between adjacent optical-electric units.

[0004] Traditional optical composite cables have poor compressive strength. When subjected to external crushing force, the internal optical fibers can be damaged or broken, leading to complete failure or severe degradation of optical signal transmission. Repairing them is extremely difficult, usually requiring the replacement of the entire cable, which necessitates power outages, resulting in very high costs and long time consumption. To address these issues, we have designed a fast-connection optical composite cable. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Example 1

[0027] Please see Figures 1-5 As shown, this embodiment proposes a quick-connect optical composite cable, including a metal sleeve 1, a male connector 2 installed at one end of the metal sleeve 1, and a female connector 3 installed at the other end of the metal sleeve 1. A cable sheath 4 is sleeved inside the metal sleeve 1, and multiple sets of cable cores 401 are fixedly installed inside the cable sheath 4. Water-blocking gel 104 is filled between the cable sheath 4 and the metal sleeve 1. An connector 201 is fixedly installed on one side of the male connector 2. Locking holes 203 are opened on both the front and back of the connector 201. An insertion slot 301 for use with the connector 201 is opened on one side of the female connector 3. Threaded sleeves 304 are fixedly installed on both the front and back of the insertion slot 301. Locking pins 305 are threadedly installed inside the threaded sleeves 304.

[0028] In use, the cable sheath 4 provides initial protection to the cable core 401. The cable core 401 transmits optical and electrical signals. The metal sleeve 1 is fitted over the cable sheath 4, providing rigid protection to the cable. The metal sleeve 1 significantly improves the cable's resistance to crushing, preventing or reducing the risk of breakage when subjected to external crushing forces, thus increasing the cable's safety and transmission stability. Water-blocking gel 104 is filled between the metal sleeve 1 and the cable sheath 4. The water-blocking gel 104 positions the cable sheath 4 within the metal sleeve 1, ensuring its stability during operation. Furthermore, the water-blocking gel 104 provides waterproofing and moisture protection for the cable. The cable core 401 is designed to provide soft cushioning support for the cable, effectively reducing the micro-bending stress caused by external vibration, impact, and compression, and protecting the cable from physical damage. The two ends of the cable core 401 are fixedly connected to a male connector 2 and a female connector 3, respectively. The plug 201 on the male connector 2 side is inserted into the slot 301 on the female connector 3 side, allowing for quick connection of the cable during use. This improves the speed of cable connection for operators. The threaded sleeve 304 has internal threads installed on a locking pin 305, which can be inserted into a locking hole 203 by rotation. The locking pin 305 and the locking hole 203 work together to lock the male connector 2 and female connector 3 during connection, ensuring the stability of the cable during rapid connection operations.

[0029] Example 2

[0030] Based on Example 1, such as Figures 1-4 As shown, a first corrugated pipe 101 is fixedly connected to the center of the metal sleeve 1, and a second corrugated pipe 102 is fixedly connected to both sides of the metal sleeve 1. A flexible sleeve 105 is fixedly installed inside the first corrugated pipe 101 and the second corrugated pipe 102, and the flexible sleeve 105 is fitted on the outside of the cable sheath 4.

[0031] In use, the first corrugated tube 101 increases the bendability at the center of the metal sleeve 1, and the second corrugated tube 102 increases the bendability on both sides of the metal sleeve 1. Thus, the cooperation of the first corrugated tube 101 and the second corrugated tube 102 facilitates the bending and adjustment of the cable by the operator during use, avoiding the situation where the rigidity of the metal sleeve 1 prevents the operator from bending and adjusting the cable. This increases the cable's ability to bend and adjust under crushing conditions, reducing limitations. The flexible sleeve 105 is installed inside both the first corrugated tube 101 and the second corrugated tube 102, so that the flexible sleeve 105 can support the cable sheath 4 at the positions of the first corrugated tube 101 and the second corrugated tube 102.

[0032] like Figure 1As shown, both ends of the metal sleeve 1 are fixedly installed with connecting plates 103, which are fixedly connected to the male connector 2 and the female connector 3 respectively.

[0033] In use, the connecting plate 103 facilitates the connection and fixation of the metal sleeve 1, the male connector 2, and the female connector 3, and improves the stability of the connection between the male connector 2 and the female connector 3 and the metal sleeve 1, thus preventing the connection from breaking due to external force pulling the cable during use.

[0034] like Figure 3 and Figure 4 As shown, the top and bottom of the plug 201 are fixedly installed with positioning plates 202, and the top and bottom of the connector 3 are provided with positioning grooves 302 that cooperate with the positioning plates 202.

[0035] When in use, when the plug 201 is inserted into the socket 301, the positioning plate 202 is simultaneously inserted into the positioning groove 302. Thus, the positioning plate 202 and the positioning groove 302 can position the male connector 2 and the female connector 3 during connection, preventing the male connector 2 and the female connector 3 from rotating and breaking apart during connection.

[0036] like Figure 2 As shown, the outer wall of the flexible sleeve 105 has multiple sets of bending grooves 106 at equal intervals.

[0037] In use, the bending groove 106 facilitates the bending adjustment of the flexible sleeve 105, thereby making it easy for the flexible sleeve 105 to bend synchronously with the first corrugated pipe 101 or the second corrugated pipe 102, and avoiding the situation where the flexible sleeve 105 breaks during the bending process.

[0038] like Figure 2 As shown, multiple sets of reinforcing rings 107 are equidistantly sleeved on the outside of the water-blocking gel 104, and the outer wall of the reinforcing ring 107 abuts against the inner wall of the metal sleeve 1.

[0039] In use, the reinforcing ring 107 can provide support and reinforcement for the interior of the metal sleeve 1. The reinforcing ring 107 improves the rigidity of the metal sleeve 1, avoids or reduces the possibility of the metal sleeve 1 being dented or deformed when subjected to rolling, and improves the cable's resistance to rolling during use.

[0040] like Figure 3 As shown, a sealing gasket 303 is externally fixedly installed on one side of the female connector 3.

[0041] When in use, the sealing gasket 303 can flexibly seal the connection between the male connector 2 and the female connector 3, preventing rainwater from seeping into the interior through the connection between the male connector 2 and the female connector 3, thus improving the safety of cable connection.

[0042] Working principle: The cable core 401 transmits optical and electrical signals. The cable sheath 4 provides initial protection for the cable core 401. The metal sleeve 1 provides rigid protection for the cable core 401. The metal sleeve 1 increases the cable's resistance to crushing. The water-blocking gel 104 provides waterproofing and moisture-proofing for the cable and provides soft cushioning support, effectively reducing the micro-bending stress caused by external vibration, impact, and compression. The first corrugated tube 101 and the second corrugated tube 102 can be bent while the metal sleeve 1 provides rigid protection for the cable, reducing limitations.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
