Description

Technical Field

[0001] The present invention relates to the technical field of circuit testing, and in particular to an identification device for a marine multi-core cable. Background Art

[0002] With the ocean shipping industry's growing demand for ship capacity and the advancement of domestic shipbuilding technology, domestic shipbuilders have seen a rapid increase in orders for large-tonnage ships in recent years. This increase in tonnage has effectively increased the size of ships and the number of cabins within them. Furthermore, various types of cables are required to connect the various cabins to ensure the stable operation of numerous systems within the ship, such as communications and navigation. Therefore, large-tonnage ships use cables that are numerous, long, and require complex laying routes. Furthermore, to better transmit multi-link data, a single cable often contains multiple cores of the same specification. This makes it difficult for workers to quickly identify the corresponding connectors at both ends of a multi-core cable or a specific connector to be found during cable laying and subsequent maintenance, increasing the difficulty of daily maintenance.

[0003] Traditionally, multi-core cables used in large-tonnage ships primarily rely on manual exhaustive identification of connectors. This involves a worker at the head of the cable connecting one core connector to the shielded wire. A worker at the tail of the cable, using a multimeter, then connects all the core connectors in that section to the shielded wire one by one. Once the multimeter indicates a connection, the identification of that core connector is complete. The worker at the head of the cable then selects another core connector and repeats the identification process. This method is not only inefficient for multi-core cable identification but also time-consuming and laborious. Furthermore, it is affected by the tester's professional skills and proficiency, indirectly increasing the probability of identification errors during manual operation.

[0004] Realizing the rapid identification of multi-core cables for large-tonnage ships can not only reduce the probability of errors in cable identification and connection caused by human operation during the laying of multi-core cables, and reduce the difficulty of cable inspection and maintenance for subsequent personnel, but also provide effective guarantees for the timely and quality delivery of ships, greatly enhancing my country's comprehensive strength in large-tonnage shipbuilding.

[0013] Optionally, the outlet housing hub is fixed to the outlet housing by screws, the outlet port of the electrical signal receiving unit hub is connected to the inlet port of the outlet housing hub by a wire, the bus clamp is connected to the outlet port of the outlet housing hub by a wire, and the bus clamp is used to connect to the tail end of the multi-core cable shielding wire, thereby realizing the electrical connection between the outlet port of the electrical signal receiving unit hub and the tail end of the multi-core cable shielding wire.

[0033] like Figures 1 to 5As shown, the present invention provides a device for identifying multi-core marine cables, comprising an adjustable power transmission module and a multi-node electrical signal detection module at the outlet end; wherein,

[0034] The adjustable power transmitter module includes: an adjustable power transmitter device 1, a power output terminal connector (including a power output terminal clamp 2, a power output terminal aviation plug quick connector terminal 3), and a shielded wire clamp 4;

[0035] The power output terminal connector (power output terminal clamp 2, power output terminal aviation plug quick-connect terminal 3) is connected to the positive pole of the adjustable power transmitter 1 through a wire, and the power output terminal connector is used to connect to any core wire at the head end of the multi-core cable, and the shielding wire clamp 4 is connected to the negative pole of the adjustable power transmitter 1 through a wire, and the shielding wire clamp 4 is used to connect to the head end of the shielded wire of the multi-core cable; the shielding wire here refers to the conductor layer used for electromagnetic shielding in the cable (usually a braided copper mesh or metal foil), and the outer surface of each core wire is wrapped with an insulating layer, and the shielding wire wraps all the core wires inside.

The bus clamp 12 is used to connect to the tail end of the multi-core cable shielded wire.

[0040] The following describes in detail the use of the cable identification device of the present invention through specific embodiments.

[0041] Example 1

[0042] See attached Figure 6 , a device for identifying multi-core cables for ships, which can quickly identify multi-core cables for large-tonnage ships in the pre-wiring (bare wire) state. The implementation process is as follows:

[0043] The first step is to determine the output voltage of the adjustable power transmitter 1 and the number of modular electrical signal receiving units to be installed based on the number and specifications of the multi-core cable for the ship to be tested;

[0044] In the second step, connect the shielded wire clamp 4 to the shielded wire at the head end of the multi-core cable for the ship to be tested, connect all the core wires at the tail end of the multi-core cable for the ship to be tested to the output end clamp 5 on the electrical signal receiving unit respectively, and connect the bus clamp 12 to the shielded wire at the tail end of the multi-core cable for the ship to be tested.

[0045] In the third step, the power output clamp 2 is connected to the numbered core wire C1 at the head of the multi-core cable for ships to be tested. The worker at the head end of the cable turns on the adjustable power transmitter 1. At this time, the core wire C1 forms a path with the entire identification device, and a path LED light 7 on the tail end line of the multi-core cable to be tested is lit. According to the lit path LED light, the worker at the tail end of the cable can complete the identification and marking of the core wire C1.

[0046] In the fourth step, the worker at the head end of the cable turns off the adjustable power transmitter 1, connects the power output clamp 2 to the numbered core wire C2 at the head of the multi-core cable to be tested and turns on the adjustable power transmitter 1. The worker at the tail end of the cable completes the identification and marking of the core wire C2 through the lit path LED light 7.

[0047] Step 5: Repeat the operation process in step 4 to complete the identification of all core wires of the multi-core cable for the ship to be tested.

[0048] Example 2

[0049] See attached Figure 7 A device for identifying multi-core cables for ships, which can quickly detect multi-core cables for large-tonnage ships in the post-wiring (aviation plug) state. The implementation process is as follows:

[0050] The first step is to determine the output voltage of the adjustable power transmitter 1 and the number of modular electrical signal receiving units to be installed based on the number and specifications of the multi-core cable for the ship to be tested;

[0051] In the second step, connect the shielded wire clamp 4 to the shielded wire at the head end of the multi-core cable for the ship to be tested, connect the aviation plug quick-connect terminal 6 on the output end of the electrical signal receiving unit to the aviation plug at the tail end of the multi-core cable to be tested, and connect the bus clamp 12 to the shielded wire at the tail end of the multi-core cable for the ship to be tested.

[0052] The third step is to connect the power output terminal aviation plug quick-connect terminal 3 to the A1 port of the aviation plug at the head of the multi-core ship cable to be tested. The worker at the head end of the cable turns on the adjustable power transmitter 1. At this time, the core wire connected to the A1 port of the aviation plug forms a path with the entire identification device. A certain path LED light 7 on the tail end of the multi-core cable to be tested is illuminated. At this time, the worker at the tail end of the cable determines the line that illuminates the path LED light 7 and observes the number of the aviation plug socket connected to the aviation plug quick-connect terminal 6 at the output end. If the aviation plug interface number is A1, the wiring of the aviation plugs at both ends is correct. Otherwise, it means that the wiring of the connectors at both ends is incorrect, and the incorrect connection head can be quickly found from the line where the path LED light 7 is illuminated and corrected in time.

[0053] In the fourth step, the worker at the head end of the cable turns off the adjustable power transmitter 1, connects the power output end aviation plug quick connect terminal 3 to the aviation plug A2 port of the head of the multi-core cable to be tested and turns on the adjustable power transmitter 1. The worker at the tail end of the cable completes the detection of the corresponding channel cable aviation plug connector number through the lit channel LED light 7.

[0054] Step 5: Repeat the operation process in step 4 until all aviation plug ports of the multi-core cable for ships to be tested are tested.

[0055] In summary, the present invention provides an identification device for multi-core cables for ships. The identification device connects the two ends of the core wire to form a loop with the help of the shielding wire inside the cable, and realizes rapid identification and detection through the on-off detection of the parallel circuit in the multi-node electrical signal detection module at the outlet end. The LED display light is used to realize the identification and matching of the two ends of the core wire. The entire identification and detection process is visualized, which reduces the difficulty of identification. Compared with the multi-core cable connector identification work performed by the traditional manual exhaustive method, the device greatly improves the identification efficiency of multi-core cables for large-tonnage ships and reduces the probability of cable identification and connection errors caused by human operation. At the same time, the clamps and aviation plug quick-connect terminals can meet the rapid connection of the ends of multi-core cables with different specifications and different wiring conditions, meeting diversified needs. In addition, the modular installation of the electrical signal receiving unit in the multi-node electrical signal detection module at the outlet end can meet the rapid identification needs of multi-core cables with different numbers of core wires.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
