Description

Technical Field

[0001] The present application relates to the technical field of pre-branching cables, and in particular to a ship-based pre-branching cable. Background Art

[0002] As an important component for information and power energy transmission, power cables are widely used in various industries. Due to the limited space on ships and the lightweight of ships, the laying of lines on ships is even more important. Ship DC cables use high current and low voltage systems in specific places, and multiple cables are required for laying power. In the cabin, more wiring devices are required for cable branching, so branch cables are used.

[0003] In the branch cables currently in use, when the main cable is branched into two slave cables for connection, a connecting wire clamp is set at the connection. When the cable is used to connect the equipment, if the connecting wire is not long enough, a pulling force will occur when the equipment is connected to the connecting wire, causing tension to be applied to the connecting wire clamp of the cable. If this continues for a long time, the main cable and the branch cable will be broken. Therefore, a marine pre-branching cable is designed to solve the above-mentioned problem. Utility Model Content

[0022] The following is combined with Figure 1-3 This application is described in further detail.

[0023] The present application embodiment discloses a pre-branching cable for ship. Figure 1-3A marine pre-branching cable comprises a protection frame 1, a connecting wire clamp 2 is fixed in the protection frame 1, a main cable 3 is installed on one side of the connecting wire clamp 2, and a connecting branch cable 4 is fixed on the side of the connecting wire clamp 2 away from the main cable 3. Figure 1 As shown, both the main cable 3 and the branch cable 4 are provided with mounting rings 5, and the mounting ring 5 on the main cable 3 has a larger diameter than the mounting ring 5 on the branch cable 4;

[0024] The front parts of the mounting rings 5 ​​on the branch cable 4 and the main cable 3 are fixedly connected to the mounting block 9, the mounting block 9 is fixedly connected to the adjusting frame 10 on one side close to the middle of the protection frame 1, the adjusting frames 10 are threadedly connected to the threaded rod 11 on one side close to each other, the threaded rod 11 is fixedly connected to the fixing rod 12 on the side away from the adjusting frame 10 on the same side, and the fixing rods 12 are fixedly connected to the worm gear 13 on one side close to each other.

[0025] The worm 14 drives the worm wheel 13 to rotate, so that the worm wheel 13 drives the fixed rod 12 to rotate, the fixed rod 12 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the adjusting frame 10 on the same side to move, and makes the adjusting frame 10 move in the direction close to the worm wheel 13, the adjusting frame 10 drives the mounting block 9 to move, so that the mounting block 9 drives the mounting ring 5 to move, and the mounting ring 5 pulls the main cable 3 and the branch cable 4 close to the connecting wire clamp 2, and always provides tension to keep the main cable 3 and the branch cable 4 connected to the connecting wire clamp 2, so that the connection between the main cable 3 and the branch cable 4 is protected, avoiding the tension generated when the equipment is connected to the pre-branching cable from directly acting on the connecting wire clamp 2.

[0026] By adopting the above technical solution, the upper end of the worm wheel 13 meshes with the worm 14, and the worm 14 is rotatably connected to the inner wall of the protection frame 1. The worm 14 can be easily fixed, so that the rotation of the worm wheel 13 driven by the worm 14 is more stable, and the front part of the worm 14 is fixedly connected to the turning handle 6, and the turning handle 6 is rotatably connected to the inner wall of the protection frame 1, and the turning handle 6 can be used to drive the worm 14 to rotate, thereby adjusting the worm wheel 13.

[0027] By adopting the above technical solution, the front part of the mounting ring 5 is threadedly connected to the screw rod 7, and the lower end of the screw rod 7 passes through the inner wall of the mounting ring 5 and is rotatably connected to the pressing plate 8. The pressing plate 8 is arc-shaped, so that the pressing plate 8 can effectively clamp the cable. The pressing plate 8 presses the cable screw rod 7 away from the side of the mounting ring 5 and is fixedly connected to the handle, and the handle is located outside the mounting ring 5. The screw rod 7 can be rotated to drive the pressing plate 8 to move, and the cable is clamped by the combined force of the pressing plate 8 and the mounting ring 5, thereby fixing the cable.

[0028] The implementation principle of a marine pre-branching cable in the embodiment of the present application is as follows: the branch cable 4 and the main cable 3 are respectively connected to the required equipment or power supply. After the connection, the handles on the mounting ring 5 can be rotated respectively, so that the handles drive the screw rod 7 to rotate, and the screw rod 7 drives the pressure plate 8 to move, so that the pressure plate 8 presses the cable line, and the cable line is clamped and fixed by the combined action of the inner wall of the mounting ring 5 and the pressure plate 8, and then the turning handle 6 can be rotated to drive the worm 14 to rotate, and the worm 14 drives the worm wheel 13 to rotate, so that the worm wheel 13 drives the fixed rod 12 to rotate, and the fixed rod 12 drives the threaded rod 11 By rotating, the threaded rod 11 drives the adjusting frame 10 on the same side to move, and makes the adjusting frame 10 move in the direction close to the worm gear 13. The adjusting frame 10 drives the mounting block 9 to move, and the mounting block 9 drives the mounting ring 5 to move. The mounting ring 5 pulls the main cable 3 and the branch cable 4 close to the connecting clamp 2, and always provides tension to keep the main cable 3 and the branch cable 4 connected to the connecting clamp 2, so as to prevent stress from being applied to the connection between the main cable 3 and the branch cable 4 in the connecting clamp 2 when being pulled by the equipment, so as to avoid the tension breaking the connection between the main cable 3 and the branch cable 4 and causing disconnection.
