Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to a multi-branch integrated cable and a manufacturing method thereof. Background Art

[0002] When transmitting power supply or control signals in an underwater power control system, it is necessary to connect underwater cables for transmitting power and signals between each power supply device and the user terminal. When connecting different user terminals with power supply equipment or control equipment, cables of different models and specifications will be configured according to the needs of the terminals. Generally, there will be a variety of power control equipment in the entire power control system. Traditionally, multiple cables will be bundled together to form a cable bundle, which will be cut to a suitable length before installation and connected as required on devices with different functions. Although this method can meet the requirements of use and installation, it has problems such as large outer diameter of the cable bundle, heavy weight, poor bending, uneven cable bundle, and messy wire bundles that are difficult to install, resulting in high costs, high safety risks, and increased load on the ship.

[0003] The structure of traditional cables is a cable with a uniform and complete appearance. The core wires inside the cable only need to be continuously twisted into shape by a cabling machine, and the outside is continuously wrapped with a sheath. Branch cables are proposed in the prior art, which branch out multiple branches on the main cable to meet complex usage needs. However, in the existing branch cables, the core wires of the branch lines are usually connected externally and soldered to the corresponding core wire conductors in the main cable by soldering. The integrity of the core wires is poor and the tensile capacity is poor, which is not conducive to the transmission of electricity or signals. In the invention patent "A branch cable and its manufacturing method" with application number CN202211739193.3, a branch cable is provided, which is formed by losslessly leading out the core wires in the main cable, but the branches of this cable are only branched out from the main cable, and the head ends of the internal core wires are all located at the ends of the main cable, that is, the starting sections of the core wires inside the entire cable are concentrated in one place, which is difficult to meet the usage needs in complex situations. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a multi-branch integrated cable and a manufacturing method thereof, in which the beginning and end of the internal core wire can be flexibly set as needed to meet dynamic needs in complex situations.

[0046] The main working principle of the multi-branch integrated cable involved in the present invention is: the starting end protection mechanism 1 serves as a protection mechanism at the starting end of the multi-branch integrated cable as a whole. For the core wire 5 in the starting end protection mechanism 1, according to actual needs, the core wire 5 in any one of the sheath tubes of type A sheath tube 12, type B sheath tube 13 and type C sheath tube 14 can pass through the first connector 11 and extend to another sheath tube. The ends of the core wire 5 in the type A sheath tube 12 and the type C sheath tube 14 are located at the wiring terminal 4 for connecting to the equipment, while the core wire 5 in the type B sheath tube 13 extends into the second connector 21 of the intermediate protection mechanism 2. For the core wires 5 in the intermediate protection mechanism 2, the part of the core wires 5 coming from the B-type sheath tube 13 of the starting protection mechanism 1, each of the core wires 5 can enter the D-type sheath tube 22 or the E-type sheath tube 23 of the intermediate protection mechanism 2 via the second connector 21 as needed, and at the same time, any E-type sheath tube 23 can also be provided with a core wire 5 entering the D-type sheath tube 22 or entering another E-type sheath tube 23 via the second connector 21, and the end of the core wire 5 in the E-type sheath tube extends to the terminal 4 at the end for connection with the equipment, while the core wire 5 in the D-type sheath tube 22 extends into the second connector 21 of the next intermediate protection mechanism 2, or extends into the third connector 31 of the terminal protection mechanism 3. For the core wires 5 in the end protection mechanism 3, each of the core wires 5 coming from the D-type sheath tube 22 of the middle protection mechanism 2 can enter an F-type sheath tube 32 via the third connector 31 as needed. In addition, a core wire 5 can also be arranged in one of the F-type sheath tubes 32 to enter another F-type sheath tube 32 via the third connector 31. Therefore, the protective sheath device forms a tree-like structure with multiple forks by setting a starting protection mechanism 1, several intermediate protection mechanisms 2 and several terminal protection mechanisms 3, and selecting appropriate forms, quantities and connection methods according to actual needs. The C-type sheath tube 14, E-type sheath tube 23 and F-type sheath tube 32 in the multi-branch integrated cable and the core wire 5 inside thereof constitute a branch line, and the end of the branch line is a wiring terminal 4. The entire multi-branch integrated cable has multiple wiring terminals 4, and the wiring terminals 4 can be flexibly set according to actual needs. According to wiring needs, the two ends of the core wire 5 can be set at any two wiring terminals 4. The core wire 5 selects a suitable path from the protective sheath device to pass through one or more of the starting protection mechanism 1, the intermediate protection mechanism 2 and the terminal protection mechanism 3, so as to meet various usage needs, especially in complex wiring occasions, to achieve flexible wiring. For any core wire 5, it is a complete core wire 5, without external connection problems, to protect the integrity of the core wire 5, to ensure the stability of power transmission and the accuracy of signal transmission, and to prevent interference between signals.

[0047] In this embodiment, as a preferred design, see Figure 1The first connector 11, the second connector 21 and the third connector 31 are all injection molded parts, which are fixedly connected to each sheath tube by injection molding. The first connector 11, the second connector 21 and the third connector 31, the A-type sheath tube 12, the B-type sheath tube 13, the C-type sheath tube, the D-type sheath tube 22, the E-type sheath tube 23 and the F-type sheath tube 32 are all made of the same material, and specifically, the material commonly used as the insulating protective sheath in the cable can be used, for example, polyurethane or other types of plastic rubber materials can be used, and have appropriate flexibility so that the cable can be bent. When manufacturing the first connector 11, the first connector 11 is injection molded between the A-type sheath tube 12, the B-type sheath tube 13 and the C-type sheath tube 14, and is fixedly connected to these three types of sheath tubes and sealed; similarly, when manufacturing the second connector 21 of the intermediate protection mechanism 2, it is injection molded between its own D-type sheath tube 22 and the E-type sheath tube 23, and the B-type sheath tube 13 or the D-type sheath tube 22 connected to the second connector 21 (depending on whether the second connector 21 is preceded by the starting protection mechanism 1 or the intermediate protection mechanism 2), and the first connector 11 is fixedly connected to these sheath tubes, and the connection is kept sealed; similarly, when manufacturing the third connector 31 of the terminal protection mechanism 3, it is injection molded between the F-type sheath tube 32 and the D-type sheath tube 22, and the third connector 31 is fixedly connected to these sheath tubes, and the connection is kept sealed. By adopting the above method, each branch point of the multi-branch integrated cable (the first connector 11, the second connector 21 and the third connector 31) can maintain good sealing, can be used underwater, and the connection of the branch line is stable and reliable.

[0048] In this embodiment, as a preferred design, both ends of the core wire 5 are respectively provided with the same mark, so as to facilitate the determination of the positions of the two ends of the same core wire 5, and different core wires 5 have different marks to distinguish them and facilitate wiring. Specifically, heat shrink tubes can be provided at both ends of the core wire 5, and the same number is printed on the heat shrink tubes as a mark.

[0049] In this embodiment, as a preferred design, the core wires 5 in the A-type sheath tube 12, the B-type sheath tube 13, the C-type sheath tube 14, the D-type sheath tube 22, the E-type sheath tube 23 and the F-type sheath tube 32 are twisted into cables when multiple strands are twisted into cables, and the gaps are filled with water-blocking filling materials when they are twisted into cables, and at the same time, the core wires 5 of the cable are wrapped with flexible water-blocking tapes.

[0050] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the B-type sheath tube 13 of the starting protection mechanism 1 is one, the C-type sheath tube 14 can be multiple or one, the D-type sheath tube 22 of the intermediate protection mechanism 2 is one, and the E-type sheath tube 23 can be multiple or one. Among them, the intermediate protection mechanism 2 can be divided into multiple levels according to the connection relationship, see Figure 1 As shown, the intermediate protection mechanism 2 connected to the B-type sheath tube 13 of the starting protection mechanism 1 is recorded as the first-level intermediate protection mechanism 2, the intermediate protection mechanism 2 connected to the D-type sheath tube 22 of the first-level intermediate protection mechanism 2 is recorded as the second-level intermediate protection mechanism 2, and the intermediate protection mechanism 2 connected to the D-type sheath tube 22 of the second-level intermediate protection mechanism 2 is recorded as the third-level intermediate protection mechanism 2, and so on to the n-th level intermediate protection mechanism 2. Each level of intermediate protection mechanism 2 can be set to one or more. Figure 1 Specifically, there are three levels as shown, and each level is an intermediate protection mechanism 2 , and the D-shaped sheath tube 22 of the third-level intermediate protection mechanism 2 is connected to a terminal protection mechanism 3 .

[0051] See also Figure 1 , the multi-branch integrated cable of the present invention is explained with the specific example shown. Since the A-type sheath tube 12 and the B-type sheath tube 13 of the starting protection mechanism 1 are both one, and the D-type sheath tube 22 of the first and second intermediate protection mechanisms 2 (the intermediate protection mechanisms 2 of each level before the last level) is also one, the path portion where the A-type sheath tube 12, the B-type sheath tube 13, and the D-type sheath tube 22 of the first and second intermediate protection mechanisms 2 are located can be recorded as the main cable portion of the cable, wherein the section where the A-type sheath tube 12 is located can be recorded as the main cable section I, the section where the B-type sheath tube 13 is located can be recorded as the main cable section II, and the sections where the two C-type sheath tubes 14 are located can be recorded as branch sections I and branch sections II, and the cross sections at the main cable section I, the main cable section II, the branch section I, and the branch section II are respectively referred to. Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the main cable section I has multiple core wires 5, the type and quantity of the core wires 5 can be set as needed, and each core wire 5 can be wrapped with multiple sub-core wires. For example, the core wire 5 can be a 22AWG shielded twisted pair cable, a 24AWG shielded twisted pair cable, a 22AWG data bus, etc., which include multiple sub-core wires. The core wires 5 that need to be twisted can be twisted according to the design requirements. After twisting, they are coated with polyester tape, and the CAN line is coated with aluminum tape. After wrapping, they are braided and shielded. After the core wire 5 in the main cable section I passes through the first connector 11, according to the branch lead-out design, part of the core wire 5 is separated and led out, and enters the branch section I and the branch section II, and the rest enters the main cable section II. At the same time, a CAN line is incorporated into the branch section I, and twisted with the core wire 5 from the main cable section I into a cable, which is wrapped by a C-type sheath tube 14 for protection. The CAN line incorporated in the branch section I passes through the first connector 11 and is incorporated into the main cable section II; two 22AWG single wires are incorporated into the branch section II, and twisted with the core wire 5 led out of the main cable section I into a cable, which is wrapped by a C-type sheath tube 14 for protection. The other ends of the two 22AWG single wires incorporated in the branch section II pass through the first connector 11 and are incorporated into the main cable section II; the core wire 5 in the main cable section II then enters the first-level intermediate protection mechanism 2 for subsequent branching. See. Figure 1 and Figure 3 The first-level intermediate protection mechanism 2 has a D-type sheath tube 22 and an E-type sheath tube 23. The section where the D-type sheath tube 22 is located can be recorded as the main cable section III, and the section where the E-type sheath tube 23 is located can be recorded as the branch section III. The main cable section II is forked at the second connector 21 of the first-level intermediate protection mechanism 2, and is divided into the main cable section III and the branch section III. The core wire 5 can also be incorporated into the branch section III and enter the main cable section III through the second connector 21. The arrangement of the core wire 5 in the intermediate protection mechanism 2 can be the same or similar to that in the starting protection mechanism 1, so it will not be described in detail. After the cable is branched at each level of the intermediate protection mechanism 2, the D-type sheath tube 22 of the last third-level intermediate protection mechanism 2 is respectively connected to a terminal intermediate protection mechanism 2, and the cable is branched at the terminal intermediate protection mechanism 2. The above is only a specific example of the multi-branch integrated cable of the present invention, and is not a specific limitation on the structure of the present invention.

[0052] The present invention also provides a method for manufacturing the above-mentioned multi-branch integrated cable, comprising the following steps:

[0053] S1. Wiring of core wires 5: Determine the position of the terminal 4 at both ends of each core wire 5 and the layout path of the core wire 5, and arrange the core wires 5; multiple core wires 5 located in the same sheath tube will form a core wire 5 harness, and preferably twisted into a cable. Among them, the wiring of the core wires 5 can start from the beginning of the multi-branch integrated cable (the end where the beginning protection mechanism 1 is located), and the intermediate protection mechanisms 2 are recorded as the first-level intermediate protection mechanism 2 to the nth-level intermediate protection mechanism 2 in sequence according to the connection order. The wiring can be carried out in the order from the first-level intermediate protection mechanism 2 to the nth-level intermediate protection mechanism 2; the wiring method specifically includes:

[0054] S11. Wiring of branch wires at the starting protection mechanism 1: first determine the core wire 5 in the A-type sheath tube 12 of the starting protection mechanism 1 (i.e., the core wire 5 in the main cable section I), and then separate the core wire 5 at the position of the first connector 11 according to the design requirements, into the core wire 5 in the B-type sheath tube 13 and the core wire 5 in the C-type sheath tube 14. If the C-type sheath tube 14 also contains the core wire 5 that is not in the A-type sheath tube 12, then the core wire 5 is merged into the core wire 5 in the C-type sheath tube 14 and twisted together into a cable. At the same time, the other end of the core wire 5 is merged into the core wire 5 in the B-type sheath tube 13 after passing through the position of the first connector 11, and twisted together into a cable. Specifically, Figure 1 In the embodiment shown, the core wire 5 of the main cable section I is divided into three parts, namely the core wire 5 in the main cable section II, the branch section I and the branch section II. At the same time, other core wires 5 are incorporated into the branch section I and the branch section II, and enter the main cable section II around the position of the first connector 11.

[0055] S12, branch wiring of the intermediate protection mechanism 2, including:

[0056] S121. Wiring of the first-level intermediate protection mechanism 2 connected to the starting protection mechanism 1: The core wire 5 in the B-type sheath tube 13 belonging to the starting protection mechanism 1 is separated at the location of the second connector 21 of the first-level intermediate protection mechanism 2, and is divided into the core wire 5 in the D-type sheath tube 22 and the core wire 5 in the E-type sheath tube 23. If the E-type sheath tube 23 also has a core wire 5 that is not in the B-type sheath tube, the core wire 5 is merged into the core wire 5 in the E-type sheath tube 23 and twisted together into a cable. At the same time, the other end of the core wire 5 is merged into the core wire 5 in the D-type sheath tube 22 after passing through the location of the second connector 21, and twisted together into a cable. Specifically, Figure 1 In the embodiment shown, the core wire 5 of the main cable section II is divided into two parts, namely the core wire 5 of the main cable section III and the branch section III. At the same time, other core wires 5 are incorporated into the branch section III and enter the main cable section III around the position of the second connector 21.

[0057] S122 , in the same manner as the line arrangement at the first-level intermediate protection mechanism 2 , line arrangement is performed in subsequent intermediate protection mechanisms 2 step by step.

[0058] S13. Branch wiring at the end protection mechanism 3: the core wire 5 in the D-type sheath tube 22 belonging to the intermediate protection mechanism 2 is divided into several parts at the location of the third connector 31 of the end protection mechanism 3, which are respectively the core wires 5 in several E-type sheath tubes 23. If the E-type sheath tube 23 also has a core wire 5 that is not in the D-type sheath tube 22, the core wire 5 is merged into the core wire 5 in the E-type sheath tube 23, and twisted together into a cable. At the same time, the other end of the core wire 5 is merged into the core wire 5 in another E-type sheath tube 23 after passing through the location of the third connector 31, and twisted together into a cable.

[0059] S2. At the corresponding positions, the A-type sheath tube 12, the B-type sheath tube 13 and the C-type sheath tube 14 of the starting protection mechanism 1 are manufactured and wrapped around the corresponding core wires 5. The A-type sheath tube 12, the B-type sheath tube 13 and the C-type sheath tube 14 can be manufactured after all the wiring work of the core wires 5 is completed, or after the arrangement of the core wires 5 at the starting protection mechanism 1 is completed. The A-type sheath tube 12, the B-type sheath tube 13 and the C-type sheath tube 14 can be manufactured by injection molding or other suitable methods.

[0060] The D-type sheath tube 22 and the E-type sheath tube 23 of each intermediate protection mechanism 2 are manufactured and wrapped with the corresponding core wire 5 harness. Similarly, the D-type sheath tube 22 and the E-type sheath tube 23 can be manufactured after all the core wire 5 wiring work is completed, or can be manufactured in time after the core wire 5 at the intermediate protection mechanism 2 is arranged. The D-type sheath tube 22 and the E-type sheath tube 23 can be manufactured by injection molding or other suitable methods.

[0061] The F-type sheath tube 32 of the terminal protection mechanism 3 is manufactured and wrapped around the corresponding core wire 5. The F-type sheath tube 32 can be manufactured after all the wiring work of the core wires 5 is completed, or it can be manufactured in time after the arrangement of the core wires 5 at the terminal protection mechanism 3 is completed. The F-type sheath tube 32 can be manufactured by injection molding or other suitable methods.

[0062] S3. Make the first connector 11 of the starting protection mechanism 1, connect it with the A-type sheath tube 12, the B-type sheath tube 13 and the C-type sheath tube 14, and keep the connection sealed. Make the second connector 21 of each intermediate protection mechanism 2, connect it with its own D-type sheath tube 22 and E-type sheath tube 23, and keep the connection sealed. At the same time, the A-type sheath tube 12 of the starting protection mechanism 1 or the D-type sheath tube 22 of the intermediate protection mechanism 2 connected to the intermediate protection mechanism 2 is also fixedly connected to the second connector 21, and the connection is kept sealed. Make the third connector 31 of the terminal protection mechanism 3, connect it with the E-type sheath tube 23, and keep the connection sealed. At the same time, the D-type sheath tube 22 of the intermediate protection mechanism 2 connected to the terminal protection mechanism 3 is also connected to the third connector 31, and the connection is kept sealed. The first connector 11, the second connector 21 and the third connector 31 are all made by injection molding. The injection mold used is determined according to the bifurcation of each connector, and the corresponding designs include one-to-two structure, one-to-three structure and two-to-three structure. The injection molding material is selected from the same specification material as each sheath tube. During the injection molding process, the temperature, pressure and flow rate are controlled to ensure that the injection molded part is tightly bonded to the cable.

[0063] S4. After the first connector 11, the second connector 21 and the third connector 31 at all branches are injection molded, the electrical performance of each section is tested, and a white heat shrink tube printed with the same number is heat-shrunk on each core wire 5 as a mark. Heat shrink tubes can also be set on each branch line (composed of the C-type sheath tube 14, the E-type sheath tube 23 and the F-type sheath tube 32 and the core wire 5 inside) to mark the branch line.

[0064] The head end of the main cable (i.e. the beginning end of the A-type sheath tube 12) and the ends of each branch line (i.e. the ends of the C-type sheath tube 14, the E-type sheath tube 23 and the F-type sheath tube 32) can be connected to a watertight connector for vulcanization and sealing.

[0065] As can be seen from the above, the multi-branch integrated cable and the manufacturing method thereof of the present invention have the following beneficial effects:

[0066] 1. The entire multi-branch integrated cable has multiple terminals 4, which can be flexibly set according to actual needs, and according to wiring needs, the two ends of the core wire 5 can be set at any two terminals 4. The core wire 5 selects a suitable path in the protective sleeve device for wiring, which meets various usage needs, especially for complex wiring occasions, and realizes flexible wiring. For any core wire 5, it is a complete core wire 5, without external connection problems, protecting the integrity of the core wire 5, ensuring the stability of power transmission and the accuracy of signal transmission, and preventing interference between signals.

[0067] 2. The length of each section of the branch line and the distance between each branch point can be controlled according to the needs of the user terminal. It is easy to manufacture, the tolerance can be controlled within ±2cm, and it is flexible to use. Each section of the branch line is integrated into a cable as a unit. Each branch line only needs one layer of sheath, which effectively reduces the additional weight, makes it easy to control the roundness of the structure, saves space, and reduces the outer diameter and weight.

[0068] 3. The materials of each sheath tube and the injection molding material of the connector are of the same type. The connection is stabilized by injection molding, and the connection is processed to make it tightly bonded and well sealed, which can meet the overall and each branch point's ability to withstand 6.75MPa lateral water pressure. By selecting suitable materials, the ultra-flexible performance of a small bending radius can be met. It can be used in a variety of instruments and equipment, such as power control equipment, lighting equipment, detection equipment, etc. in ships and submarines.

[0069] In summary, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

Anyone familiar with 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 a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
