Description

Technical Field

[0001] This utility model relates to the field of communication cable technology, and in particular to a novel composite glass fiber hard wire cable. Background Technology

[0002] Traditional fiberglass conductors use a single multi-core insulated copper conductor as the signal carrier; their process control and production are relatively simple. When used as a power supply transmission carrier, there are few problems; however, when used as a signal transmission carrier, the lack of a signal shielding layer makes signal transmission highly susceptible to external interference and interference between signals; furthermore, the signals passing through the conductor itself can generate electromagnetic interference to the outside world.

[0003] Its performance is particularly poor in signal transmission within endoscopes.

[0004] Therefore, the applicant designed a new type of composite cable; after multiple optimizations and adjustments, it can achieve stable and reliable signal transmission and power supply; at the same time, its structural form can be well adapted to various pipe and cavity environments that the endoscope needs to enter. Utility Model Content

[0018] Preferably, the thickness of the insulating skin is 1 to 1.5 mm.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1 A novel composite fiberglass rigid cable is composed of: a rigid fiberglass core 1, power supply cores 2 and communication cores 3 arranged around the rigid fiberglass core 1, and an outermost insulating layer 4.

[0029] The communication core 3 is a coaxial cable.

[0030] Furthermore, preferably, two communication cores 3 are symmetrically arranged.

[0031] It can be used as a primary and backup line, so that when the primary line fails, the backup line can quickly take over to ensure the continuity of signal transmission; it can also be used to transmit signals simultaneously, improving the efficiency and flexibility of signal transmission.

[0032] This cable is suitable for signal transmission; it is especially suitable for video signal transmission in industrial endoscopes.

[0033] This cable features an innovative internal coaxial cable core, which effectively resists external electromagnetic interference, ensuring reliable and stable signal transmission. Furthermore, it does not generate external interference. Additionally, a separate power supply cable is provided, fully meeting the power supply and data transmission needs of the equipment. Overall, it offers excellent performance and has a wide range of applications.

[0034] Preferably, the communication core 3 is of φ0.87, RF1.37 specification, or φ0.68, RF1.13 specification, or φ0.41, RF0.81 specification.

[0035] With a small outer diameter, it can meet the signal transmission requirements; at the same time, it is suitable to be integrated with the rigid glass fiber core 1 and the power supply core 2 into a single form; and the overall wire diameter is appropriate.

[0036] Preferably, the power supply core 2 is enameled wire.

[0037] Furthermore, the power supply core 2 is enameled copper wire.

[0038] Using insulated enameled copper wire as a power transmission line has the advantages of a large conductor cross-sectional area, which can carry a large current and a small voltage drop. At the same time, the enameled wire has only a thin layer of insulating varnish, which makes the overall outer diameter small. This is conducive to better matching and setting with other wire cores in a limited cable space, so as to achieve the compactness and rationality of the overall cable structure.

[0039] The power supply core 2 is an enameled wire with a diameter of 0.3~0.5 mm.

[0040] Preferably, the power supply core 2 is an enameled wire with a diameter of 0.5 mm.

[0041] With appropriate conductor specifications, the power supply requirements of equipment such as industrial endoscopes can be fully met; and while ensuring sufficient current carrying capacity, the outer diameter of the cable will not be affected by excessively thick conductors.

[0042] In some embodiments, the power supply core 2 is provided with two or four wires.

[0043] It should be noted that at least two power supply cores 2 should be provided to ensure power supply; four cores are optional and can be used to meet other needs, such as backup circuits or control signal circuits.

[0044] In some embodiments, it further includes: a filling layer 5 covering the outside of the rigid glass fiber core 1; the power supply core 2 and the communication core 3 are embedded in the filling layer 5.

[0045] Preferably, the filling layer 5 is glass fiber; during production, glass fiber covers the rigid glass fiber core 1, the power supply core 2 and the communication core 3 to form the filling layer 5; and the power supply core 2 and the communication core 3 are controlled to be evenly and circumferentially distributed.

[0046] It should be noted that:

[0047] The rigid fiberglass core 1 in the middle position has a high hardness, and the flexibility of the entire cable is controlled by the hardness of the core. It is prefabricated and has a large diameter. During the manufacturing process, enameled wire and coaxial cable are wrapped around the rigid fiberglass core 1. By adding filler material (fiberglass + adhesive), pressure and heat are applied to complete a complete composite fiberglass cable. After completion, an insulating plastic covering material is then applied to the surface.

[0048] The outer diameter of the filling layer 5 is 4-5 mm.

[0049] Preferably, the outer diameter of the filling layer 5 is 4 mm; by reasonably controlling the outer diameter of the filling layer 5, the relative position between the cores inside the cable can be kept stable, thereby improving the service life and reliability of the cable.

[0050] It is understandable that the outer diameter of the filling layer 5 minus the outer diameter of the rigid glass fiber core 1 is the thickness of the filling layer 5; we control the overall size and calculate the data of the filling layer 5 accordingly.

[0051] The diameter of the rigid glass fiber core 1 is 2 to 2.5 mm.

[0052] Preferably, the diameter of the rigid glass fiber core 1 is 2.5 mm to ensure that the whole has suitable rigidity.

[0053] The thickness of the insulating skin 4 is 1 to 1.5 mm.

[0054] Preferably, the insulation sheath 4 has a thickness of 1.5 mm. In various endoscopic environments of industrial endoscopes, such as humid and corrosive environments, the insulation sheath 4 plays a crucial protective role. An insulation sheath 4 of appropriate thickness can effectively prevent the internal core of the cable from contacting the external environment, avoiding safety accidents such as short circuits and leakage, and ensuring the safe and reliable use of the cable. At the same time, the insulation sheath 4 also has a certain mechanical strength, which can withstand the external impact and friction that may be subjected to during use, further improving the durability of the cable.

[0055] This invention provides a composite cable suitable for industrial endoscopes; it is particularly suitable for scenarios where internal images of engine cavities, pipe internal structures, and other structures need to be viewed.

[0056] In this utility model, a coaxial cable is innovatively incorporated, and a composite method of coaxial cable and insulated copper wire is used for synergistic cooperation; the flexibility of the entire cable is controlled by the rigid glass fiber core 1 in the middle; the filling layer 5 works with the rigid glass fiber core 1 to form a uniform and surrounding distribution of the power supply core 2 and the communication core 3; the outermost insulation layer 4 ensures the safety and reliability of the cable.

[0057] In this invention, the signal shielding layer of the coaxial cable enables stable transmission of high-speed digital signals, avoiding the disadvantages of traditional insulated copper wires. Simultaneously, its unique structure effectively resists external electromagnetic interference, and its constant impedance ensures stable and reliable signal transmission. Furthermore, the signal shielding layer prevents signal leakage, avoiding electromagnetic interference to surrounding electronic equipment and systems, and ensuring electromagnetic compatibility in complex industrial environments. The use of two symmetrically arranged communication cores provides both primary and backup redundancy, ensuring continuous transmission, and the ability to transmit multiple signals simultaneously, improving transmission efficiency and flexibility, and meeting the video signal requirements of industrial endoscopes.

[0058] In this invention, insulated enameled copper wire is used as the power transmission line, which has advantages such as a large conductor cross-sectional area, allowing for large current carrying capacity and low voltage drop. At the same time, the thin insulating varnish results in a small overall outer diameter, which is beneficial for cooperation with other wire cores and achieving a compact and reasonable cable structure. In addition, the small diameter of the power supply core 2 can meet the power supply requirements without affecting the cable's outer diameter. Furthermore, the power supply core 2 can be configured as two or four wires. Two wires can meet basic power supply needs, while four wires can expand the backup circuit or control signal transmission function, making it more flexible and reliable.

[0059] In this invention, the hardness and diameter of the rigid glass fiber core 1 are used to effectively control the cable flexibility, meeting the requirements of industrial endoscopes for both flexibility and rigidity; the filling layer 5 is made of glass fiber, which makes each core evenly distributed around the cable, and its thickness is reasonably set to ensure the stability of the relative position of the cores and improve the service life of the cable; the outermost insulation layer effectively prevents safety accidents such as short circuits and leakage under various endoscopic environments, and has a certain mechanical strength, enhancing the durability of the cable.
