Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically a high-temperature resistant and fireproof ship cable. Background Technology

[0002] As the core carrier of power transmission and signal control on ships, the reliability of the plug-in structure of shipboard cables directly affects the operational stability of all shipboard equipment. With the increasing integration of shipboard equipment and the growing complexity of operating conditions, the frequency of cable connections has significantly increased, especially in scenarios involving rapid interconnection between power systems, navigation equipment, and weapon units, placing higher demands on plug connection efficiency. Current mainstream shipboard cable plug-in technologies mainly rely on threaded or spring-clamp structures, which have significant application drawbacks: Firstly, plug-to-socket connections require manual tightening of multiple turns of the thread or precise clamping, with each connection typically taking over 30 seconds. This severely impacts operational efficiency in emergency repairs or frequent debugging scenarios. Furthermore, some high-protection-level plugs require the assistance of wrenches or other tools for tightening, further increasing operational complexity.

[0003] Based on this, a high-temperature resistant and fireproof ship cable is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-temperature fireproof ship cable includes: an outer sheath, a connector sleeve, a protective unit, and a quick-connect mechanism.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-6 As shown, a high-temperature fireproof ship cable includes: an outer sheath 1, a connector sleeve 2, a protective unit, and a quick-connect mechanism. The connector sleeve 2 is fitted onto the bottom end of the outer sheath 1. The inner wall of the outer sheath 1 is provided with a protective unit for conductive protection. The inner wall of the connector sleeve 2 is fixedly provided with a quick-connect mechanism for quickly connecting the cable to power.

[0027] In one embodiment, such as Figure 2 As shown, the protective unit includes a shielding layer 3 disposed on the inner wall of the outer sheath 1, a fireproof layer 4 disposed on the inner wall of the shielding layer 3, an insulating layer 5 disposed on the inner wall of the fireproof layer 4, and a conductor layer 6 disposed inside the insulating layer 5.

[0028] The shielding layer 3 is made of tin-plated copper wire braid, which has electromagnetic interference (EMI) resistance. The surface of the fireproof layer 4 is coated with an intumescent flame-retardant coating.

[0029] The high-temperature resistance is improved by wrapping double-layer mica tape around the insulation layer 5. The intumescent flame-retardant coating on the surface of the fireproof layer 4 expands when exposed to fire, thus isolating oxygen. The cable is protected from stretching by setting a tinned copper wire braided shielding layer 3. This cable can be used on ships to achieve high-temperature resistance and fire protection, thus improving electrical safety.

[0030] In one embodiment, such as Figures 3-6As shown, the quick-connect mechanism includes a mounting block 7 fixedly disposed on the inner wall of the connector sleeve 2, a pressure block 8 fixedly disposed on the outside of the outer sheath 1, a first sliding rod 9 slidably disposed on the inner wall of the connector sleeve 2 and the mounting block 7, the end of the first sliding rod 9 being fixedly connected to the pressure block 8, a first spring 10 being sleeved around the periphery of the first sliding rod 9, the end of the first spring 10 being fixedly connected to the mounting block 7 and the pressure block 8, and a folding assembly for storing the plug being fixedly disposed on the inner wall of the connector sleeve 2.

[0031] A limiting block is fixed at the end of the first sliding rod 9 to prevent the first sliding rod 9 from falling off.

[0032] By fitting the connector sleeve 2 onto the end of the outer sheath 1, and then, guided by the first sliding rod 9, the first spring 10 drives the mounting block 7 to reset, so that the mounting block 7 presses the connector sleeve 2, thus completing the rapid installation of the connector sleeve 2.

[0033] The folding assembly includes a mounting bracket 11 fixedly disposed on the inner wall of the connector sleeve 2. A connecting rod 12 is rotatably disposed on the inner wall of the mounting bracket 11. A first plug 13 is fixedly disposed on the connecting rod 12, and a second plug 14 is fixedly disposed on the connecting rod 12 on the other side. A connecting rod 15 is fixedly disposed at both ends of the connecting rod 12. A second sliding rod 16 is rotatably disposed at the end of the connecting rod 15, and a sliding sleeve 17 is rotatably disposed at the end of the connecting rod 15 on the other side. The second sliding rod 16 and the sliding sleeve 17 are slidably connected. A second spring 18 is sleeved around the second sliding rod 16, and the end of the second spring 18 is fixedly connected to the sliding sleeve 17.

[0034] Connect plug 13 to the neutral and live wires respectively, and connect plug 14 to the ground wire.

[0035] By manually rotating plug 13 and plug 14, they can be folded and stored. Plug 13 and plug 14 drive the connecting rod 12 to rotate, which in turn drives the connecting rod 15 to rotate. Simultaneously, the second sliding rod 16 slides in the sliding sleeve 17 and compresses the second spring 18. At this time, a protective sleeve can be installed at the bottom of the connector sleeve 2 to protect the plugs. When needed, the second spring 18 drives the second sliding rod 16 and the sliding sleeve 17 to reset, thereby unfolding plug 13 and plug 14 and inserting them into the socket to provide power. This eliminates the wiring steps required for traditional ship cables, improves power supply efficiency, and enhances convenience for the crew.

[0036] The above embodiments disclose a high-temperature fireproof shipboard cable, wherein the cable insulation layer 5 is wrapped with double-layer mica tape, which significantly improves the high-temperature resistance; the surface of the fireproof layer 4 is coated with an intumescent flame-retardant coating, which expands upon contact with fire to form a dense carbonized layer to isolate oxygen; an outer tin-plated copper wire braided shielding layer 3 is added, which enhances tensile strength through a metal mesh structure. The triple composite design works synergistically to enable the cable to have both high-temperature fire resistance and mechanical protection functions in the harsh environment of shipboard high temperature and vibration, ensuring the safety of power transmission; during installation, the connector sleeve 2 is fitted onto the end of the outer sheath 1, and the first sliding rod 9 guides the first spring 10 to push the mounting block 7 to reset and tighten, realizing rapid fixing of the connector. The plugs 13 and 14 are manually folded. The connecting rod 12 and the connecting rod 15 drive the second sliding rod 16 to slide within the sliding sleeve 17 and compress the second spring 18, so that the plugs are retracted into the protective sleeve. When in use, the second spring 18 returns to its original position and pushes the second sliding rod 16 to return to its original position along the sliding sleeve 17. The plug unfolds and is inserted into the socket to provide power. This eliminates the wiring steps required for traditional ship cables, improves power supply efficiency, and increases convenience for the crew.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
