[0002] In the railway communication signal system, the cable box and its connector interface are key components that bear the important task of signal transmission. However, in actual applications, some cable boxes use a main interface to connect multiple secondary interfaces, using a one-to-many connection method. When the cable box connector interface fails, the interface often cannot be replaced in time. This is mainly due to the lack of a quick replacement mechanism and the limitation of insufficient reserved interfaces. In addition, when the connector fails, since there is no reserved cable, maintenance personnel need to lay out the cable at the reserved cable location, which not only increases the complexity and time cost of maintenance, but also may greatly reduce maintenance efficiency.

[0003] Furthermore, when faced with emergency maintenance situations, maintenance personnel may choose to forcibly connect cables and connectors to restore signal transmission as quickly as possible.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0023] An embodiment of the present application provides a cable box for railway communication signals, which can solve the problem in the related art that when a cable box connector interface fails, the interface often cannot be replaced in time, and there is no reserved cable. Maintenance personnel need to lay out the cable at the reserved cable location, which increases the complexity and time cost of maintenance.

[0024] See also Figure 1-Figure 3 A cable box for railway communication signals comprises a shell 1, wherein the shell 1 is provided with two reserved chambers 2 and an installation chamber 3 for accommodating cables, wherein a reel 10 is provided inside the reserved chamber 2, and the reel 10 is used to reel in the cable, and wherein a plurality of connectors 4 are provided inside the installation chamber 3, and the connectors 4 are used for connecting the cables.

[0025] The connector 4 includes a base plate 41, a connection seat 42 and a group of connectors 43. The base plate 41 is arranged inside the installation chamber 3, the connection seat 42 is arranged on the base plate 41, and a group of connectors 43 are relatively arranged above the base plate 41. The connectors 43 are used to connect cables, wherein the connection seat 42 is electrically connected to the connectors 43.

[0026] The housing 1, as the outer structure of the entire cable box, provides sufficient protection so that it can adapt to various environmental conditions. A reel 10 is provided inside the reserved chamber 2 for reeling in excess cables. When the cables are not in use, they can be neatly stored in the reserved chamber 2 by the reel 10 to avoid clutter of cables.

[0027] The installation chamber 3 is the core area of ​​the cable box, in which several connectors 4 are arranged. The structure of the connector 4 includes a base plate 41, a connection seat 42 and a group of connectors 43. The base plate 41 is fixed inside the installation chamber 3 to provide a stable support for the connection seat 42; the connection seat 42 is installed on the base plate 41 and is electrically connected to the connector 43. The electrical connection between the connection seat 42 and the connector 43 ensures the stable transmission of signals between the cables; the connector 43 is the key part of the cable connection, which is relatively arranged above the base plate 41 to facilitate the insertion and connection of the cable. When the cable needs to be connected to the cable box, the cable connection can be achieved by simply inserting the end of the cable into the connector 43.

[0028] In actual operation, when the connector 4 or the joint on the cable fails, the maintenance personnel can open the shell 1 of the cable box and directly access the installation chamber 3. Since there is a spare cable rolled up by the reel 10 in the reserved chamber 2, the maintenance personnel can quickly pull out the cable from the reel 10 and replace the joint on the cable as needed. After the replacement is completed, it is connected to the corresponding joint 43 without the need for additional wire-laying operations, thereby greatly improving the maintenance efficiency.

[0029] When the connector 4 fails, a suitable connector 43 is selected from the multiple connectors 43 on the connector 4 for connection, so as to achieve the purpose of quick replacement. After the replacement is completed, the base plate 41 is removed and the replaced connector 4 is repaired or replaced.

[0030] In summary, the device can quickly replace the cable interface. At the same time, by reserving cables, the staff does not need to perform additional line laying operations, which makes the operation more convenient and saves time and cost, thereby greatly improving the maintenance efficiency and realizing efficient maintenance operations, providing reliable hardware support for the stable transmission of railway communication signals.

[0031] It should be noted that the bottom plate 41 is connected to the installation chamber 3 by bolts.

[0032] Specifically, in this embodiment, the connector 4 includes a connection seat 42 structure composed of:

[0033] Base portion: The base portion is the portion that is in direct contact with the bottom plate 41 and is usually made of a strong and durable material to ensure its stability and durability. The base portion can be designed to have a certain thickness to increase the mechanical strength of the connection base and provide a stable support for other components.

[0034] Conductive terminals: Conductive terminals are provided inside the connection base 42. These conductive terminals are responsible for realizing the transmission of electrical signals between cables. The conductive terminals are usually made of materials with good conductive properties, such as copper or copper alloy, to ensure the stability and reliability of signal transmission.

[0035] Insulation layer: In order to ensure the safety and stability of the cable connection, an insulation layer is provided between the conductive terminals of the connection base 42 and between the conductive terminals and the housing. The insulation layer is usually made of insulating material, such as plastic or rubber, which can effectively isolate the conductive parts and prevent electrical faults or short circuits.

[0036] Interface part: The interface part of the connection socket 42 is the part that directly connects with the connector 43, and its shape and size must match the connector 43 to ensure smooth connection and signal transmission.

[0037] In this embodiment, the connectors 43 on the plurality of connectors 4 may be of various types.

[0038] By adopting a variety of connector types, it can be ensured that the connector can adapt to the connection requirements of various devices and systems, thereby improving the versatility and compatibility of the connector.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, a group of partitions 5 are relatively arranged inside the shell 1, and the group of partitions 5 and the shell 1 are separated to form two reserved chambers 2 and an installation chamber 3, and the installation chamber 3 is located between the two reserved chambers 2, wherein the reserved chamber 2 is circular, and the partition 5 and the shell 1 are integrally cast.

[0040] The reserved chamber 2 is designed to be circular, and this shape may help to provide uniform space distribution. The circular design also tends to provide better space utilization and is conducive to the storage of cables.

[0041] Secondly, the partition 5 and the shell 1 are integrally cast. This manufacturing process can ensure that the connection between the partition 5 and the shell 1 is firm and stable, and is not prone to loosening or deformation. Integral casting can also reduce the assembly gap between components, thereby improving the sealing and stability of the entire structure.

[0042] like Figure 2 As shown, in this embodiment, a plurality of branching tubes 6 are arranged on the partition plate 5 , and the branching tubes 6 are used to guide the cables into the installation chamber 3 , and a sealing rubber ring is arranged inside the branching tubes 6 .

[0043] The main function of these branching tubes 6 is to guide the cables into the interior of the installation chamber 3. Such a design not only facilitates the management and layout of the cables, but also helps to maintain the neatness and orderliness of the entire system.

[0044] In this embodiment, a receiving tube 7 is disposed on the shell 1 , and the receiving tube 7 is used for the cable to extend into the reserved chamber 2 . A sealing rubber ring is disposed inside the receiving tube 7 .

[0045] The provision of the accommodating tube 7 ensures that the cable can enter the reserved chamber 2 safely and stably, and avoids wear or damage to the cable during the insertion process.

[0046] A sealing rubber ring is also provided inside the accommodating tube 7, which can fit tightly between the cable and the accommodating tube 7, effectively preventing water, dust or other impurities from entering the reserved chamber 2 through the accommodating tube 7. This not only protects the equipment in the reserved chamber 2 from the influence of the external environment, but also improves the stability and reliability of the entire system.

[0047] In another embodiment, a plurality of accommodating tubes 7 are relatively arranged on the shell 1 in this embodiment.

[0048] The provision of multiple receiving tubes 7 means that more cables can be accommodated and managed at the same time, greatly improving the flexibility and convenience of cable wiring. This is particularly suitable for complex systems that need to handle a large number of cables, which can effectively reduce wiring confusion and improve the overall neatness and maintainability of the system.

[0049] It should be noted that a sealing rubber ring is provided inside the receiving tube 7. Each receiving tube 7 can provide effective sealing performance to prevent water, dust or other impurities from entering the reserved chamber 2. This comprehensive sealing protection can ensure that the equipment in the reserved chamber 2 is always in a good working environment and extend the service life of the equipment.

[0050] Specifically, Figure 4 As shown, the reel 10 in this embodiment includes a winding post 101 and a baffle 102 . The winding post 101 is arranged inside the reserved chamber 2 , and the baffle 102 is arranged at the end of the winding post 31 .

[0051] The main function of the winding post is to provide a space for cable winding so that the cables can be wound thereon in an orderly manner and the cables can be conveniently rolled up and released, making cable management simple and efficient; the baffle 102 can prevent the cables from slipping off the winding post 101 during the winding process, ensuring that the cables can be stably fixed on the reel 10.

[0052] The housing 1 is provided with a sealing cover 8, a sealing strip 1 is provided between the sealing cover 8 and the housing 1, and a sealing strip 2 is provided between the sealing cover 8 and the partition plate 5. The sealing cover 8 and the housing 1 are connected by bolts.

[0053] The sealing cover 8 improves the sealing performance of the entire system, ensuring that the equipment inside the reserved chamber 2 and the installation chamber 3 is protected from the influence of the external environment.

[0054] A sealing strip 1 is provided between the sealing cover 8 and the housing 1, which can effectively fill the small gap between the two and prevent water, dust or other impurities from entering the chamber through these gaps. At the same time, the use of the sealing strip 1 can also enhance the connection stability between the cover and the housing and improve the overall sealing effect.

[0055] A sealing strip 2 is also provided between the sealing cover 8 and the partition 5, and the contact surface between the sealing strip 2 and the partition 5 can also maintain a sealed state, so that the reserved chamber 2 and the installation chamber 3 are in a separated and closed state to prevent potential leakage.

[0056] In order to facilitate the installation and removal of the sealing cover 8, a bolt connection is adopted between the sealing cover 8 and the housing 1. This connection method is not only simple and easy to operate, but also can provide sufficient connection strength to ensure that the sealing cover 8 can fit tightly on the housing 1 when closed. At the same time, the bolt connection also facilitates the maintenance or replacement of the sealing cover 8 when necessary.

[0057] The main function of the reinforcing ribs 9 is to increase the bending, torsion and tensile resistance of the shell, thereby improving the bearing capacity of the entire structure. By properly arranging the reinforcing ribs 9, the influence of external forces on the shell 1 can be effectively dispersed and offset to prevent it from deformation or damage.
