[0002] In the field of shipbuilding and marine engineering, instrument control cables are key components to ensure the normal operation of various equipment and signal transmission. With the continuous improvement of ship automation and intelligence, the performance requirements for instrument control cables are also increasing. Especially in the complex and changeable marine environment, cables not only need to have excellent electrical transmission performance, but also good insulation, corrosion resistance and reliable connection stability to ensure the stable operation of various ship systems.

[0003] At present, the connection methods of marine instrument control cables mainly adopt welding, crimping or fasteners to achieve the connection between cables.

[0004] However, although the welding method provides a firm connection, the operation is complicated, the environment and skills are high, and it is not easy to repair and replace. Although the crimping method is relatively simple to operate, it requires special crimping tools and molds, which are expensive, and different molds are required for cables of different specifications and sizes, which has poor flexibility. Although the method of fixing with fasteners solves the connection problem to a certain extent, the installation process is cumbersome, and in harsh environments such as vibration and impact, the connection parts are prone to loosening or falling off, affecting the reliability and safety of the cable. Summary of the invention

[0005] The purpose of this application is to provide an integral insulated marine instrument control cable, which solves the connection stability requirements between cables and greatly saves installation time and cost; and can adapt to the connection requirements of cables of different specifications and sizes, so that the cable has broad application prospects in the fields of ships, marine engineering, etc.

[0006] To achieve the above-mentioned purpose, the present application provides an integral insulated marine instrument control cable, including a composite cable and a clamping mechanism, wherein one end of the composite cable is movably connected to a conductive cable, and the other end is fixedly provided with a connector, and the connector is provided with a plurality of connecting holes; the clamping mechanism includes a connecting cable, a clamping tube and a clamping block, and a plurality of clamping blocks are fixedly provided on the inner wall of the connecting hole, and the clamping tube is rotatably provided at the connecting cable port, and a plurality of avoidance grooves are provided at one end of the clamping tube close to the connecting cable port, and a clamping groove is provided on the side wall of the avoidance groove, and the clamping tube and the port of the connecting cable are inserted into the connecting hole together, and the size of the clamping groove is adapted to the clamping block.

[0007] As a further solution of the present invention: a connecting sleeve is rotatably provided on the outer peripheral wall of one end where the conductive cable is connected to the composite cable, the connecting sleeve is threadedly matched with the conductive cable, and a first limiting ring is provided on the outer peripheral wall of the composite cable, and the first limiting ring limits the connecting sleeve.

[0008] As a further solution of the present invention: the connecting sleeve is threadedly matched with the composite cable, and a first sealing ring is arranged inside the connecting sleeve, a sealing groove is arranged at the port where the composite cable is connected to the conductive cable, and the first sealing ring is adapted to the sealing groove.

[0009] As a further solution of the present invention: a second sealing ring is provided on the outer peripheral wall of the clamping tube, and the second sealing ring seals the connecting hole.

[0010] As a further solution of the present invention: the size of the avoidance groove is larger than the size of the block.

[0011] As a further solution of the present invention: a rotation groove is provided on the outer peripheral wall of the connecting cable, and the clamping tube is rotatably matched with the rotation groove.

[0012] As a further solution of the present invention: a plurality of friction stripes are arranged at the bottom of the clamping groove.

[0013] As a further solution of the present invention: a protective sleeve is rotatably provided on the outer peripheral wall of the connector, the protective sleeve is threadedly connected to the connector and protects the clamping tube.

[0014] As a further solution of the present invention: a second limiting ring is arranged on the outer peripheral wall of the composite cable, and the second limiting ring limits the protective sleeve.

[0015] As a further solution of the present invention: the length of the card tube inserted into the connecting hole is adapted to the depth of the connecting hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the card tube and the port of the connecting cable are inserted into the connecting hole of the composite cable connector together, since the size of the avoidance groove is larger than the size of the card block, during the insertion of the card tube, the card block passes through the avoidance groove. When the card tube is inserted to the bottom of the connecting hole, the card tube is rotated. Since the size of the card slot matches the card block, the card block will be firmly stuck in the card slot, thereby achieving a stable connection between the composite cable and the connecting cable, greatly saving installation time and cost; and it can adapt to the connection requirements of cables of different specifications and sizes, so that the cable has a wide range of application prospects in the fields of ships, marine engineering, etc.

[0018] 2.

When the connecting sleeve is screwed onto the composite cable, the first sealing ring will be compressed and tightly fit in the sealing groove, thereby forming an effective sealing structure to prevent moisture, dust and other external substances from entering the connection part. This helps to improve the safety and reliability of the entire cable system.

[0019] 3. The present invention increases the friction between the card block and the card slot by arranging the friction stripes, thereby improving the stability of the connection and preventing the connection from loosening due to factors such as vibration and impact.

[0021] 5. The present invention ensures that the length of the card tube inserted into the connection hole is adapted to the depth of the connection hole, thereby ensuring that the card tube can be fully inserted into the connection hole and fully cooperate with the card block to achieve a stable card connection, while avoiding the problem of unreliable connection caused by insufficient insertion depth.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] like Figures 1 to 8 As shown, an integral insulated marine instrument control cable comprises a composite cable 1 and a clamping mechanism, wherein one end of the composite cable 1 is movably connected to a conductive cable 3, and the other end is fixedly provided with a connector 2, and the connector 2 is provided with a plurality of connection holes 21; the clamping mechanism comprises a connection cable 4, a clamping tube 5 and a clamping block 22, and a plurality of clamping blocks 22 are fixedly provided on the inner wall of the connection hole 21, and the clamping tube 5 is rotatably provided at the port of the connection cable 4, and a plurality of avoidance grooves 51 are provided at one end of the clamping tube 5 close to the port of the connection cable 4, and a clamping groove 52 is provided on the side wall of the avoidance groove 51, and the clamping tube 5 is inserted into the connection hole 21 together with the port of the connection cable 4, and the size of the avoidance groove 51 is larger than the size of the clamping block 22, and the size of the clamping groove 52 is adapted to the size of the clamping block 22.

[0034] When the card tube 5 and the port of the connecting cable 4 are inserted into the connecting hole 21 on the connector 2 of the composite cable 1, since the size of the avoidance groove 51 is larger than the size of the block 22, the block 22 passes through the avoidance groove 51 during the insertion of the card tube 5. When the card tube 5 is inserted to the bottom of the connecting hole 21, the card tube 5 is rotated. Since the size of the card slot 52 matches the block 22, the block 22 will be firmly stuck in the card slot 52, thereby realizing a stable connection between the composite cable 1 and the connecting cable 4. The operation is very simple and quick. Compared with the traditional connection method, it does not need to be fixed with fasteners such as screwdrivers and nuts, thereby greatly saving installation time and cost; at the same time, since the block 22 is firmly stuck in the card slot 52, it will not loosen or fall off even in harsh environments such as vibration and impact.

[0035] The composite cable 1 adopts an integral insulation design, and the clamping mechanism is also made of insulating material. Therefore, this connection method not only ensures the electrical connection between the cables, but also ensures good insulation performance, thereby improving the safety of the entire cable system, and can adapt to the connection requirements of cables of different specifications and sizes, making the cable have a wide range of application prospects in the fields of ships, marine engineering, etc.

[0036] A connecting sleeve 6 is rotatably provided on the outer peripheral wall of one end of the conductive cable 3 connected to the composite cable 1, and the connecting sleeve 6 is threadedly matched with the conductive cable 3 to achieve the connection between the conductive cable 3 and the composite cable 1;

[0037] A first limiting ring 11 is provided on the outer peripheral wall of the composite cable 1, and the first limiting ring 11 limits the connection sleeve 6. The connection sleeve 6 is threadedly matched with the composite cable 1, and a first sealing ring 61 is provided inside the connection sleeve 6. A sealing groove 12 is provided at the port where the composite cable 1 is connected to the conductive cable 3, and the first sealing ring 61 is adapted to the sealing groove 12.

[0038] During the connection process, the connection sleeve 6 is first screwed onto the conductive cable 3, and then aligned with the composite cable 1 and rotated until the first stop ring 11 stops the connection sleeve 6 from rotating further. At this time, the first sealing ring 61 has been compressed and fits tightly in the sealing groove 12 to ensure the sealing of the connection part.

[0039] The first limiting ring 11 is provided to limit the movement range of the connecting sleeve 6, thereby ensuring that the relative position between the connecting sleeve 6 and the composite cable 1 is fixed; at the same time, a first sealing ring 61 is provided inside the connecting sleeve 6, and a sealing groove 12 is provided at the port where the composite cable 1 is connected to the conductive cable 3. When the connecting sleeve 6 is screwed onto the composite cable 1, the first sealing ring 61 will be compressed and tightly fit in the sealing groove 12, thereby forming an effective sealing structure to prevent external substances such as moisture and dust from entering the connection part, which helps to improve the safety and reliability of the entire cable system.

[0040] A second sealing ring 7 is provided on the outer peripheral wall of the clamping tube 5. The second sealing ring 7 seals the connecting hole 21, effectively preventing external factors such as water and moisture from invading the connection, thereby improving the sealing and durability of the connection.

[0041] The outer wall of the connecting cable 4 is provided with a rotation groove 41, and the card tube 5 is rotatably matched with the rotation groove 41. Through the rotational match between the rotation groove 41 and the card tube 5, the card tube 5 is flexibly adjusted during the connection process, which facilitates alignment with the card block 22 and smooth connection.

[0042] The bottom of the clamping groove 52 is provided with a plurality of friction stripes 53. The friction stripes 53 are provided to increase the friction between the clamping block 22 and the clamping groove 52, thereby improving the stability of the connection and preventing the connection from loosening due to factors such as vibration and impact.

[0043] A protective sleeve 8 is rotatably provided on the outer peripheral wall of the connector 2, the protective sleeve 8 is threadedly connected to the connector 2 and protects the clamping tube 5. A second limiting ring 81 is provided on the outer peripheral wall of the composite cable 1, and the second limiting ring 81 limits the protective sleeve 8.

[0044] The protective sleeve 8 is provided to effectively protect the card tube 5 to prevent it from being damaged or moved due to external force, avoid the card block 22 and the card slot 52 from offsetting, avoid the phenomenon of unstable connection, improve the stability of the connection, and extend the service life of the cable.

[0045] The length of the card tube 5 inserted into the connecting hole 21 is adapted to the depth of the connecting hole 21, ensuring that the card tube 5 can be fully inserted into the connecting hole 21 and fully cooperate with the card block 22 to achieve a stable card connection, while avoiding the problem of unreliable connection caused by insufficient insertion depth.

[0046] The working principle of the present invention is as follows: one end of the composite cable 1 is connected to the conductive cable 3 by a movable connection, and the other end is fixedly provided with a connector 2. During the connection process, the clamping tube 5 and the connecting cable 4 are first inserted into the connecting hole 21 of the composite cable 1. Since the size of the avoidance groove 51 is larger than the block 22 on the inner wall of the connecting hole 21, the block 22 can smoothly pass through the avoidance groove 51. When the clamping tube 5 is inserted to the bottom of the connecting hole 21, the block 22 is firmly clamped in the clamping groove 52 by rotating the clamping tube 5, thereby realizing a stable connection between the composite cable 1 and the connecting cable 4. At the same time, in order to ensure the sealing of the connection, a threaded connection sleeve 6 is used between the conductive cable 3 and the composite cable 1, and a first sealing ring 61 is arranged inside the connection sleeve 6, which is adapted to the sealing groove 12 on the composite cable 1 to form an effective sealing structure. In addition, a second sealing ring 7 is also arranged on the outer peripheral wall of the clamping tube 5 to further seal the connecting hole 21 and prevent external factors from invading the connection. By setting the rotational cooperation between the rotating groove 41 and the card tube 5, the card tube 5 can be flexibly adjusted during the connection process. Finally, a protective sleeve 8 is also provided on the outer peripheral wall of the composite cable 1 to effectively protect the card tube 5 and improve the stability and durability of the connection. The entire cable system not only ensures the stability of the electrical connection, but also ensures good insulation and sealing performance, and has a wide range of application prospects.
