Description

Technical Field

[0001] This utility model relates to the field of shielded cable technology, and in particular to a shielded cable that is easy to disassemble. Background Technology

[0002] Shielded cables are transmission lines that use a metal mesh braid to wrap the signal lines. The braided layer is typically made of red copper or tin-plated copper, but aluminum foil wrapping is also used, among other shielding methods.12 The main purpose of shielded cables is to reduce the influence of external electromagnetic fields on power or communication lines, and it also prevents the lines from radiating electromagnetic energy. The shielding layer needs to be grounded so that external interference signals can be conducted to the ground, thereby improving signal purity and stability.

[0003] Chinese Patent CN215417599U discloses a train shielded cable that is easy to disassemble, including an outer sheath, an inner sheath coaxially disposed within the outer sheath, and several signal wires disposed within the inner sheath. The inner sheath contains, from the outside in, a shielding layer, a flame-retardant layer, a moisture-proof layer, and an insulation layer. The signal wires are arranged evenly in a circle. The outer sheath unfolds along its axial direction, with a U-shaped locking block on one side and a U-shaped slot on the other. The inner sheath unfolds along its axial direction, with a trapezoidal locking block on one side and a trapezoidal slot on the other. This application unfolds the outer sheath along its axial direction by moving the U-shaped locking block away from the U-shaped slot, and by moving the trapezoidal locking block away from the trapezoidal slot, thereby unfolding the inner sheath along its axial direction. This facilitates the replacement of damaged components by workers, and consequently, the disassembly and installation of the shielded cable.

[0004] Existing shielded cables are inconvenient to operate and disassemble, which in turn makes it difficult to disassemble the outer wall mounting components of the shielded cable. When recycling shielded cables, it is also inconvenient to disassemble the conductors and other components on the inner wall of the shielded cable, thereby reducing the secondary use efficiency of shielded cable components, increasing the production and manufacturing costs of shielded cables, and reducing the practicality of shielded cables. Utility Model Content

[0005] To address the problems existing in the background technology, a shielded cable that is easy to disassemble is proposed.

[0006] This utility model proposes a shielded cable that is easy to disassemble, comprising: an outer protective shell, a protective sleeve, a filler sleeve, and a splicing assembly;

[0007] The protective sleeve is connected to the inside of the outer protective shell;

[0010] The disassembly components include a mounting shell and an outer shell. The outer wall of the mounting shell is connected to four mounting sliders. The inner wall of the outer shell is connected to four arc-shaped blocks. The two ends of the four arc-shaped blocks respectively cooperate with the outer shell to form four sliding grooves. The four sliding grooves are respectively connected to four mounting sliders for easy disassembly of conductors, shielding components, and protective components.

[0013] The sleeve is connected with anti-slip protrusions, which are used by workers to fix and facilitate the disassembly and assembly of components.

[0014] Preferably, the protective sleeve is connected to a locking block a and a locking block b at both ends;

[0015] There are three clips a, and the gaps between the three clips a form two mounting slots. The two mounting slots are connected to clips b respectively, which are used to clamp and fix the two ends of the protective sleeve to the outer wall of the filling sleeve.

[0016] Preferably, the filler sleeve has five through holes, which are connected to five outer shells respectively, for easy disassembly of the conductor, shielding and protective components.

[0017] Preferably, the shielding element includes a shielding layer a connected to the periphery of the conductor, an insulating layer a connected to the periphery of the shielding layer, and an insulating shielding layer connected to the insulating layer a, for insulating and shielding the conductor.

The conductor, shield, and protective component are connected to the outer protective shell, protective sleeve, and filling sleeve via the mounting shell and the outer shell. The outer shell is connected to a through hole located on the filling sleeve. According to the requirements for disassembling the shielded cable, the mounting shell is moved outwards, causing the protective component, shield, and conductor to move. This facilitates the disassembly of the internal conductor components, filling sleeve, and mounting component of the shielded cable, enabling convenient recycling of shielded cable components and avoiding waste. It also helps reduce the manufacturing cost of the shielded cable. The movement of the mounting shell drives the mounting sliders, which move along the sliding grooves, facilitating guided movement and increasing the ease of disassembly between the components of the shielded cable.

[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] Example 1

[0027] like Figures 1-3As shown, this utility model proposes a shielded cable that is easy to disassemble, comprising: an outer protective shell 1, a protective sleeve 2, a filling sleeve 3, and splicing components 4; the outer protective shell 1; the protective sleeve 2 is connected inside the outer protective shell 1; the filling sleeve 3 is connected to the inner wall of the protective sleeve 2; five splicing components 4 are provided, all connected inside the filling sleeve 3; the five splicing components 4 respectively include a conductor 401, a shielding element 402, and a protective element 403 from the inside out, and the protective element 403 is connected to a disassembly component; the disassembly component includes a mounting shell 404 and an outer shell 406, and the outer wall of the mounting shell 404 is connected to four mounting sliders 405. The inner wall of the outer shell 406 is connected to four arc-shaped blocks 407. The two ends of each arc-shaped block 407, in conjunction with the outer shell 406, form four sliding grooves 408. These grooves 408 are connected to four mounting sliders 405, facilitating the disassembly of the conductor 401, shield 402, and protective component 403. The filler sleeve 3 has five through holes, each connected to one of the five outer shells 406, also facilitating the disassembly of the conductor 401, shield 402, and protective component 403. The outer shell 406, filler sleeve 3, protective sleeve 2, and outer protective shell 1 together form an installation component for connecting the shielded cable to the equipment. When the mounting shell 404 moves the protective component 403, shield 402, and conductor 401 to the protective sleeve 2, the mounting shell 404 moves, driving the mounting sliders 405. The mounting sliders 405 move along the sliding grooves 408, facilitating guided movement and increasing the ease of disassembly between the components of the shielded cable.

[0028] Further explanation: Shielding component 402 includes a shielding layer a connected to the periphery of conductor 401. Shielding layer a is connected to an insulating layer a, which in turn is connected to an insulating shielding layer, used for insulating and shielding conductor 401. Protective component 403 includes a metal shield connected to the periphery of the insulating shielding layer. The metal shield is connected to a wrapping tape, which is connected to an inner protective layer. The inner protective layer is connected to a steel tape armor layer, which is connected to an outer sheath. The outer sheath is connected to the inner wall of the mounting housing 404. Shielding layer a is used for shielding conductor 401, and insulating layer a is cross-linked polyethylene insulation, the same as insulating layer b, increasing the practicality of conductor 401. Furthermore, the protective component 403 further enhances the protection of conductor 401, facilitating improved shielded cable performance.

[0029] Example 2

[0030] like Figure 1 and Figure 2 As shown, this utility model proposes a shielded cable that is easy to disassemble. Based on the above embodiments, this embodiment also details the specific components of the outer protective shell 1 and the protective sleeve 2, as well as their matching method.

[0031] To further explain, the outer protective shell 1 is connected to the connecting shell 101, which has a slot connecting to a locking ring 102. The locking ring 102 is connected to a sleeve 103. The sleeve 103 is connected to an anti-slip protrusion 104 for workers to fix and facilitate the disassembly and assembly of the splicing component 4. When the shielded cable needs to be disassembled from the equipment, the worker clamps the anti-slip protrusion 104 to clamp the sleeve 103, and then operates to disassemble the shielded cable and equipment. This facilitates the limitation of the shielded cable and avoids affecting the disassembly operation. Furthermore, the sleeve 103 is connected to the outer protective shell 1 via the locking ring 102, preventing displacement of the sleeve 103 during the clamping operation and further improving the efficiency of disassembling the shielded cable and equipment.

[0032] To further explain, the protective sleeve 2 is connected to two locking blocks a201 and b202 at its two ends, respectively. Three locking blocks a201 are provided, with a gap between them forming two mounting slots. These two mounting slots are connected to locking blocks b202, which are used to clamp and hold the protective sleeve 2 to the outer wall of the filling sleeve 3. The protective sleeve 2 contains a shielding layer, a flame-retardant layer, a moisture-proof layer, and an insulation layer b, which helps to increase the service life of the shielded cable and improve the shielding effect. Furthermore, the protective sleeve 2, when used in conjunction with the outer protective shell 1, facilitates the connection and use of the shielded cable and equipment.

[0033] The working principle of this utility model is as follows: The easily disassembled shielded cable consists of an installation component, a disassembly component, and the shielded cable from the outside in. The shielded cable is composed of a conductor 401, a shielding component 402, and a protective component 403. This facilitates the disassembly, inspection, and reuse of the filling sleeve 3 and the shielded cable. When the shielded cable is damaged and needs to be disassembled and recycled, the installation shell 404 is removed from the outer shell 406. The installation shell 404 is connected to the outer periphery of the protective component 403, and the protective component 403 is connected to the outer periphery of the shielding component 402. The shielding component 402 is connected to the conductor 401, making... The conductor 401 can be disassembled from the outer shell 406. The outer shell 406 is connected to the inner wall of the through hole of the filling sleeve 3, which facilitates the disassembly of the conductor 401, the outer filling sleeve 3, the protective sleeve 2, and the outer protective shell 1. Disassembly, inspection, and maintenance are then carried out. New or inspected and maintained shielded cables are connected to the outer shell 406 through the mounting shell 404, so that the shielded cable and the filling sleeve 3 and other mounting components are connected. The connection with the equipment through the mounting components facilitates the use of the shielded cable, avoids waste of shielded cable components, reduces the production cost of shielded cables, and improves the use of shielded cables.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
