Description

Technical Field

[0001] This utility model belongs to the technical field of cable terminal protection devices, and particularly relates to a cable terminal anti-collision cap, an outdoor cable terminal, and a high-speed train. Background Technology

[0002] In the design and operation of high-speed trains, cable terminals are key components connecting the internal and external electrical systems, primarily used for signal transmission, power distribution, and control system connections. These cable terminals are typically exposed to the outdoor environment, facing complex operating conditions such as aerodynamic impacts at high speeds, external mechanical impacts, vibration shocks, and the effects of extreme weather conditions (sandstorms, rain, snow, hail, etc.). Currently, the protection of outdoor terminals on high-speed trains mainly relies on the cable terminal casing or simple coverings, lacking dedicated anti-collision devices, and is prone to failure and deformation under complex and harsh environments. Furthermore, the tight operating schedule of high-speed trains necessitates the rapid completion of terminal maintenance; if the cable terminal casing fails or is damaged, replacement and maintenance take too long.

[0003] Therefore, how to provide a device that is highly reliable, quick to maintain, and highly adaptable to the environment, and can effectively protect cable terminals, is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] To solve at least one of the above-mentioned technical problems, this utility model provides a cable terminal anti-collision cap, comprising:

[0005] A circular guard plate and annular protrusions along the edge of the circular guard plate;

[0006] A circular protective plate is installed at one end of the cable terminal and is detachably connected to the cable terminal.

[0007] The annular protrusion partially covers the end of the cable terminal;

[0008] The uncovered area on the circular guard plate and the annular protrusion side is provided with a cable terminal outlet.

[0009] Furthermore, annular protrusions are provided on one side of the circular guard plate; the inner side of the annular protrusions extends towards the center to form a protective wall.

[0010] Furthermore, an arc-shaped guide surface is provided at the connection between the circular guard plate and the outer side of the annular protrusion.

[0011] Furthermore, the cross-section of the annular protrusion is circular, and the diameter of the annular protrusion is greater than the thickness of the circular protective plate.

[0012] Furthermore, the central area of ​​the circular guard plate is provided with a rounded rectangular through groove.

[0013] Furthermore, on one side of the circular guard plate, there are snap-fit ​​posts arranged at intervals along the edge of the rounded rectangular through groove;

[0014] The snap-fit ​​post has a snap-fit ​​ring on its side, which snaps into the cable terminal.

[0015] Furthermore, the snap-fit ​​post has a threaded hole in the center, and is screwed to the cable terminal through the threaded hole.

[0016] Furthermore, both the circular guard plate and the annular protrusion are made of aluminum alloy, and the surface has an aluminum oxide layer formed by anodizing.

[0017] An outdoor cable terminal, comprising any of the cable terminal anti-collision caps described above.

[0018] A type of high-speed train, including any of the above-mentioned outdoor cable terminals.

[0019] This embodiment provides a cable terminal anti-collision cap. In use, a circular protective plate is placed at one end of the cable terminal, forming a rigid barrier to effectively withstand frontal impacts. An annular protrusion is positioned along the edge of the circular protective plate and partially covers the end of the cable terminal, effectively reducing lateral or oblique impacts and preventing the end of the cable terminal from being directly exposed to the external environment. The combination of the circular protective plate and the annular protrusion provides reliable protection for the cable terminal, resisting impacts from extreme weather conditions such as wind, sand, rain, snow, and hail, thus improving the overall impact resistance of the cable terminal. A terminal outlet is provided on the uncovered portion of the circular protective plate and the annular protrusion, allowing the cable terminal to extend smoothly and ensuring the stability of the electrical connection. Because the circular protective plate and the cable terminal are detachably connected, the anti-collision cap and the cable terminal can be quickly assembled or disassembled, significantly shortening the maintenance time of the cable terminal. In summary, this utility model provides a cable terminal anti-collision cap that is highly reliable, allows for rapid maintenance, has strong environmental adaptability, and effectively protects cable terminals.

[0027] This utility model provides a cable terminal anti-collision cap, see reference. Figure 1-3 It includes: a circular guard plate 1 and an annular protrusion 2 disposed along the edge of the circular guard plate 1;

[0028] A circular protective plate 1 is provided at one end of the cable terminal 100 and is detachably connected to the cable terminal 100.

[0029] The annular protrusion 2 partially covers the end of the cable terminal 100;

[0030] The uncovered area on one side of the circular guard plate 1 and the annular protrusion 2 is provided with a terminal outlet 3 of the cable terminal 100.

[0031] This embodiment provides a cable terminal anti-collision cap. In use, a circular protective plate is placed at one end of the cable terminal, forming a rigid barrier to effectively withstand frontal impacts. An annular protrusion is positioned along the edge of the circular protective plate and partially covers the end of the cable terminal, effectively reducing lateral or oblique impacts and preventing the end of the cable terminal from being directly exposed to the external environment. The combination of the circular protective plate and the annular protrusion provides reliable protection for the cable terminal, resisting impacts from extreme weather conditions such as wind, sand, rain, snow, and hail, thus improving the overall impact resistance of the cable terminal. Uncovered areas of the circular protective plate and annular protrusion are left exposed to provide terminal outlets, allowing the cable terminal terminals to extend smoothly and ensuring the stability of the electrical connection. The detachable connection between the circular protective plate and the cable terminal allows for quick assembly or disassembly of the anti-collision cap, significantly shortening the maintenance time of the cable terminal. In summary, this utility model provides a cable terminal anti-collision cap that is highly reliable, quick to maintain, and highly adaptable to various environments, effectively protecting cable terminals.

[0032] Preferred, Reference Figure 2 The annular protrusion 2 is provided on one side of the circular guard plate 1; the inner side of the annular protrusion 2 extends towards the center to form a protective wall 21.

[0033] In this embodiment, the annular protrusion is located on one side of the circular guard plate, forming concentrated protection on the cable terminal side; the protective wall formed by the annular protrusion extending inward enhances the protection against impacts from the side and in the oblique direction, further improving the protective effect.

[0034] Preferably, referring to the figure, an arc-shaped guide surface 22 is provided at the outer connection between the circular guard plate 1 and the annular protrusion 2.

[0035] In this embodiment, an arc-shaped guide surface is provided at the connection between the circular protective plate and the outer side of the annular protrusion. On one hand, the arc-shaped guide surface effectively guides the flow of external impact forces, evenly dispersing the impact force and reducing lateral or oblique impacts, thus enhancing the impact resistance of the cable terminal. On the other hand, due to the arc-shaped guide surface design, the surface of the anti-collision cap is more streamlined, effectively reducing air or other media resistance and friction. Furthermore, the arc-shaped guide surface guides windblown sand, rainwater, hail, or meltwater from snow and ice to the outside of the anti-collision cap, allowing it to fall freely and preventing the accumulation of sand or water droplets on the surface or seams of the anti-collision cap. By guiding the flow of rainwater and sand, the arc-shaped guide surface makes it less likely for these external elements to directly contact the core of the cable terminal. In this way, the cable terminal not only avoids damage from windblown sand and moisture but also maintains a long-term, high-efficiency working state.

[0036] Preferably, the cross-section of the annular protrusion is circular, and the diameter of the annular protrusion is greater than the thickness of the circular guard plate.

[0037] In this embodiment, both the circular protective plate and the annular protrusion with a circular cross-section have good symmetry, facilitating production using conventional processing techniques such as casting, injection molding, and die casting, thus significantly reducing processing costs. When the cable terminal anti-collision cap encounters vibration, the circular cross-section of the annular protrusion has good force dispersion characteristics, effectively reducing vibration transmission and mitigating the direct impact of external shocks on the cable terminal. The diameter of the annular protrusion's cross-section is greater than the thickness of the circular protective plate. Since the edge of the anti-collision cap is more prone to deformation during impact, reducing the thickness of the circular protective plate while increasing the cross-sectional diameter of the annular protrusion efficiently minimizes the weight of the anti-collision cap while providing sufficient strength, making the overall structure of the anti-collision cap more stable.

[0038] Preferred, Reference Figure 1 and Figure 2 The circular protective plate 1 has a rounded rectangular through-slot 4 in its central area. On one hand, when the anti-collision cap is impacted, the through-slot can partially absorb the impact energy, causing the protective plate to undergo slight elastic deformation, rather than directly transmitting the impact force to the cable terminal. On the other hand, the cable terminal may generate heat during long-term operation; the through-slot design enhances airflow, allowing heat to dissipate quickly and reducing the risk of overheating. More importantly, the addition of the rounded rectangular through-slot reduces weight while ensuring the overall rigidity of the circular protective plate. It also provides auxiliary installation positions for the aforementioned cable terminal terminals.

[0039] Preferred, Reference Figure 1 and Figure 3 On one side of the circular guard plate 1, there are snap-fit ​​posts 5 arranged at intervals along the rounded rectangular through groove 4;

[0040] The snap-fit ​​post 5 has a snap-fit ​​ring on its side, and it snaps into the cable terminal 100 through the snap-fit ​​ring.

[0041] In this embodiment, spaced-apart snap-fit ​​posts are added along the edge of the rounded rectangular through-slot. These snap-fit ​​posts act as reinforcing ribs, improving the overall bending stiffness of the protective plate and making it less prone to bending or breakage under external forces. The design of the snap-fit ​​posts and snap-fit ​​rings allows for quick installation and removal from the cable terminal through an elastic snap-fit ​​structure. The spaced-apart snap-fit ​​posts provide multiple fixing points, improving the overall fixing firmness compared to a single connection method and preventing loosening or detachment. For example, six snap-fit ​​posts are evenly distributed along the rounded rectangular through-slot.

[0042] More preferably, the snap-fit ​​post has a threaded hole in the center, and is screwed to the cable terminal through the threaded hole. The dual fixing method of snap-fit ​​post + threaded hole not only provides stable axial locking with the thread, but also provides additional lateral support through the structure of the snap-fit ​​post, further improving the impact resistance of the anti-collision cap, which is especially suitable for the high-vibration environment of EMU train operation.

[0043] Preferably, both the circular guard plate and the annular protrusion are made of aluminum alloy, and the surface has an aluminum oxide layer formed by anodizing.

[0044] In this embodiment, both the circular protective plate and the annular protrusion are made of aluminum alloy. Compared with traditional plastics or ordinary steel, aluminum alloy is lightweight, has good heat dissipation, and high strength, which can meet the special usage requirements of outdoor cable terminals for high-speed trains. Aluminum alloy itself forms an oxide layer in the air, and further combined with anodizing treatment, forms an aluminum oxide layer, which can effectively improve corrosion resistance and adapt to harsh environments such as humidity, salt spray, and high pollution.

[0045] An outdoor cable terminal, comprising any of the above-mentioned cable terminal anti-collision caps.

[0046] This embodiment provides an outdoor cable terminal. The cable terminal anti-collision cap, through a combination of a circular protective plate and annular protrusions, effectively resists external forces such as impacts, drops, and mechanical compression, protecting the cable terminal from physical damage. This improves the reliability and service life of the outdoor cable terminal.

[0047] A type of high-speed train, including any of the above-mentioned outdoor cable terminals.

[0048] This embodiment presents a high-speed train. Since high-speed trains may be affected by external debris such as gravel and foreign objects during high-speed operation, the circular protective plate and annular protrusion structure of the cable terminal anti-collision cap can absorb and disperse the impact force, preventing direct damage to the cable terminal, improving the reliability of the train's circuitry and operational safety, and also reducing the impact of extreme weather such as rain, snow, hail, and sandstorms. Furthermore, the detachable design of the cable terminal anti-collision cap can significantly shorten the maintenance time of the high-speed train's cable terminals, thereby reducing operational downtime and improving train operation efficiency.

[0049] The aforementioned outdoor cable terminal and high-speed train are created based on the aforementioned cable terminal anti-collision cap. The combination of their technical effects and features will not be elaborated further here. The above embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
