[0002] Cable termination cabinets are specialized devices used for cable protection, playing a crucial role in railway signaling and communication. They feature standardized wiring, grounding protection, and intelligent monitoring, effectively ensuring the stable operation of railway signaling systems. To prevent damage to signal equipment from external lightning or power frequency currents penetrating the cable's metal shielding layer, the termination cabinet supports secondary cable termination, where specialized equipment reliably connects the cable cores to the equipment terminals, ensuring stable signal transmission. The cabinet's internal layered wiring structure allows for the orderly arrangement and fixation of cables.

[0003] The shortcomings of existing technology: Existing cables usually enter and exit the cabinet at the top and bottom, but the existing finished cabinet structure is usually fixed, which makes the entry and exit of cables not flexible enough and cannot meet the various existing installation requirements. At the same time, the cables inside the existing cabinet are usually evenly fixed on one surface, and different cables need to be intertwined and difficult to distinguish, which increases the difficulty of troubleshooting and daily maintenance. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a modular signal cable termination cabinet to solve the problem that the existing finished cabinet structure is usually fixed, which makes the entry and exit of cables inflexible. At the same time, the cables in the existing cabinet are usually uniformly fixed on one surface, and different cables need to be intertwined, which makes them difficult to distinguish.

[0005] This utility model provides the following technical solution: a modular signal cable termination cabinet, including a cabinet body, with double doors at both the front and rear ends of the cabinet body, upper thresholds detachably installed on the upper parts of both the front and rear ends of the cabinet body, and lower thresholds detachably installed on the lower parts of both the front and rear ends of the cabinet body, and a number of cable tie plates are provided in the inner cavity of the cabinet body, wherein cable management racks are provided at both the front and rear ends of several of the cable tie plates. The cable management rack includes two connectors fixedly connected to the cable tie plate. The cable management plate is fixedly connected to one side between the two connectors, and a limit rod is fixedly connected to the other side between the two connectors.

[0006] Preferably, the wire management board has a plurality of first wire binding holes and a plurality of second wire binding holes, and the positions of the first wire binding holes and the second wire binding holes are horizontally corresponding.

[0007] Preferably, several cables enter the inner cavity of the cabinet from the outside and are fixed to the cable tie plate through the second cable tie hole. The cables in the inner cavity of the cabinet are divided into upper and lower parts along the front-to-back direction, and the cables in the upper and lower parts are staggered from the outside to the inside. Several termination boxes are fixedly connected to the cable tie plate, and the cables pass through the inner cavity of the termination boxes through the cable tie plate.

[0008] Preferably, connecting rods are fixedly connected to the middle of both sides of the inner wall of the cabinet, connecting blocks are fixedly connected to both ends of the wire tying plate, the two ends of the wire tying plate are connected to the connecting rods through the connecting blocks, and several wire pressing plates are provided at both the front and rear ends of the connecting rods.

[0009] Preferably, the pressure plate includes several pressure plates, two limiting blocks are provided between two adjacent pressure plates, and connecting bolts are provided on the pressure plates, one of the pressure plates being connected to both sides of the inner wall of the cabinet.

[0011] Preferably, a monitoring unit and a fire extinguisher are installed on one side of the inner wall of the cabinet.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model allows the cabinet to be disassembled by providing an upper and lower threshold. During construction, the upper and lower thresholds can be removed to facilitate the entry and exit of cables from the top and bottom of the cabinet. This makes the cabinet structure flexible in terms of cable entry and exit, meeting various construction needs. At the same time, the two double-opening cabinet doors at the front and back allow the cabinet to be opened from both sides, facilitating the installation of the terminal cabinet and effectively improving its applicability.

[0013] 2. This utility model features a cable tie, cable management rack, and cable clamp. Cables entering from the outside are secured by the cable tie, and after being secured by the cable management rack, they extend to the left and right sides of the inner wall of the cabinet. Cables extending to the left and right sides are then secured to the inner walls of the cabinet by the cable clamp. This design prevents damage to the cables due to excessively small bending radii. Furthermore, cable management racks are installed at both the front and back of the cable tie, ensuring that outer cables do not obstruct the inner termination boxes. This allows the cables in the upper and lower parts of the cabinet to be staggered into outer and inner layers, preventing cables from tangling together, optimizing the utilization of cabinet space, reducing signal interference, and facilitating cable maintenance and management.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The modular signal cable termination cabinet involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides a modular signal cable termination cabinet, such as Figure 1 - Figure 4 As shown, the cabinet includes a cabinet body 1. Both the front and rear ends of the cabinet body 1 are equipped with double doors 2. Upper thresholds 3 are detachably installed on the upper parts of both the front and rear ends of the cabinet body 1, and lower thresholds 4 are detachably installed on the lower parts of both the front and rear ends of the cabinet body 1. The inner cavity of the cabinet body 1 contains several cable tie plates 5, with cable management racks 6 installed at both the front and rear ends of several of the cable tie plates 5. The front and rear surfaces of the cabinet are identical. The two double doors 2 allow both the front and rear ends of the cabinet body 1 to be opened. During construction, the corresponding upper thresholds 3 and lower thresholds 4 can be removed to facilitate cable entry and exit from the top and bottom of the cabinet body 1. This makes the cable entry and exit method of the cabinet body 1 flexible, meeting various construction needs. After construction, the upper thresholds 3 and lower thresholds 4 can be restored.

[0021] Furthermore, such as Figure 1 and Figure 2 As shown, the cable management rack 6 includes two connectors 61 fixedly connected to the cable tie plate 5. A cable management plate 62 is fixedly connected to one side between the two connectors 61, and a limiting rod 63 is fixedly connected to the other side between the two connectors 61. The cable management rack 6 is used to fix the cable after the steel strip and aluminum sheath have been removed. The cable passes between the limiting rod 63 and the cable management plate 62, and its position is fixed to form a cable fixing channel to prevent the cable from getting tangled.

[0022] Furthermore, such as Figure 1 and Figure 2 As shown, the cable management board 62 has several first cable tying holes 64, and the cable tying board 5 has several second cable tying holes 7. The positions of the first cable tying holes 64 and the second cable tying holes 7 are horizontally corresponding. After the cable enters the inner cavity of the cabinet 1, it is fixed to the cable tying board 5 by passing the cable tie through the second cable tying hole 7. The cable with the steel strip and aluminum sheath removed is fixed to the cable management board 62 by passing the cable tie through the first cable tying hole 64. Multiple cables are tied in accordance with regulations by fixing them in a two-way manner to prevent the cables from being scattered or loose. This fixing method can ensure that the cables are arranged in a preset path and layout. The first cable tying holes 64 and the second cable tying holes 7 help to make reasonable use of the space inside the cabinet 1 and avoid occupying too much space.

[0023] Furthermore, such as Figure 1 and Figure 2 As shown, several cables enter the inner cavity of cabinet 1 from the outside and are fixed to the cable tie plate 5 through the second cable tie hole 7. The cables in the inner cavity of cabinet 1 are divided into upper and lower parts along the front-to-back direction, and the cables in the upper and lower parts are staggered from the outside to the inside to form an outer layer and an inner layer. This division of the cables in the inner cavity of the termination cabinet into an outer layer and an inner layer optimizes the utilization of the cabinet space and reduces signal interference. Several termination boxes 8 are fixedly connected to the cable tie plate 5. The cables are located in the inner cavity of the termination boxes 8. After the steel strip and aluminum sheath of the cables fixed on the cable tie plate 5 are stripped, the cables enter the termination boxes 8 for termination operations. The inner layer is located in the upper part of the cabinet, and the outer layer is located in the lower part of the cabinet. After the termination operations of the inner and outer layer cables are completed, the cables with the steel strip and aluminum sheath removed are led out to the left and right sides of the cabinet through the cable management plate 62. The outer layer cables do not obstruct the inner layer termination boxes. All termination boxes in the termination cabinet are unobstructed, which facilitates future termination inspection and maintenance.

[0024] Furthermore, such as Figure 3 and Figure 4 As shown, connecting rods 9 are fixedly connected to the middle of both sides of the inner wall of cabinet 1. Connecting blocks 10 are fixedly connected to both ends of cable tie plate 5. The two ends of cable tie plate 5 are connected to connecting rods 9 through connecting blocks 10. Several pressure plates 11 are provided at both ends of connecting rods 9. Cables in front of cabinet 1 are fixed out by pressure plates 11. Cables entering from the left and right sides are fixed by cable management racks 6 and extend to the left and right sides of the inner wall of cabinet 1. Cables extending from the left and right sides are fixed to the inner wall of cabinet 1 by pressure plates 11. This ensures that the bending radius of all cables is greater than 15 times the cable diameter, avoiding damage to cables due to excessively small bending radius. At the same time, cable management racks 6 are provided at both ends of cable tie plate 5. The design of cable tie plate 5, cable management racks 6 and pressure plates 11 in the inner cavity of cabinet 1 ensures that the outer layer cables will not block the inner termination box 8. At the same time, the cables in different parts of cabinet 1 are arranged in multiple rows to avoid them from crossing each other, which facilitates the maintenance and management of cables.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, the pressure plate 11 includes several pressure plates 111. Two limiting blocks 112 are provided between two adjacent pressure plates 111. Connecting bolts are provided on the pressure plates 111. One of the pressure plates 111 is connected to both sides of the inner wall of the cabinet 1. The signal cable is fixed between the two pressure plates 111. The size of the limiting blocks 112 is adjusted according to the specifications of the cable so that the distance between the two pressure plates 111 is adapted to the specifications of the cable. After the fixing is completed, the position of the pressure plate 111 is fixed by connecting bolts.

[0026] Furthermore, such as Figure 3 As shown, one end of several cable tie plates 5 is fixedly connected to a longitudinal copper strip 12, and a transverse copper strip 13 is fixedly connected to the longitudinal copper strip 12. The steel strip and aluminum sheath on the cable are connected to the transverse copper strip 13 through the termination box 8. The transverse copper strip 13 is connected to the longitudinal copper strip 12, and the longitudinal copper strip 12 is connected to the ground.

[0027] Furthermore, such as Figure 1 As shown, a monitoring unit 14 and a fire extinguisher 15 are installed on one side of the inner wall of the cabinet 1. The monitoring unit 14 includes a lightning current sensor and a power frequency current sensor to monitor the intrusion lightning current and power frequency current. At the same time, it automatically monitors the fire situation inside the cabinet 1. The high-efficiency and fast fire extinguisher 15 can quickly extinguish the fire inside the cabinet 1.

[0028] The working principle of this utility model is as follows: During the construction of the termination cabinet, the corresponding upper threshold 3 and lower threshold 4 are disassembled to facilitate the entry and exit of cables from the top and bottom of the cabinet 1. This makes the cable entry and exit method of the cabinet 1 flexible and meets various construction needs. At the same time, the two double-opening cabinet doors 2 at the front and rear allow both ends of the cabinet 1 to be opened, facilitating the entry, exit, and installation of cables. Cables entering the cabinet 1 from the outside are fixed by cable ties 5. Several termination boxes 8 are fixedly connected to the cable ties 5. After the steel strip and aluminum sheath are stripped, the cables enter the termination boxes 8 for termination operations. The cables entering are fixed by the cable management rack 6. Multiple cables in the cabinet 1 are bundled according to regulations. Bundling wire is passed through the first cable tie hole 64 and the second cable tie hole 7 to fix the cables to the cable tie 5 and the cable management rack 6, preventing the cables from being scattered or loose. This fixing method ensures that the cables are arranged according to the preset path and layout. The first cable tie hole 64 and the second cable tie hole 7 help to make reasonable use of the space inside the cabinet 1 and avoid occupying too much space. After fixing, the cables extend to the left and right sides of the inner wall of the cabinet 1. The cables extending to the left and right sides are fixed to the inner walls of the cabinet 1 by the pressure plates 11. The signal cables are fixed between the two pressure plates 111. According to the specifications and dimensions of the cables, the size of the limit block 112 is adjusted so that the distance between the two pressure plates 111 is compatible with the specifications and dimensions of the cables being fixed. After fixing, the position of the pressure plates 111 is fixed with connecting bolts. This ensures that the bending radius of all cables is greater than 15 times the cable diameter, avoiding damage to the cables due to excessively small bending radii. Since cable management racks 6 are set at both the front and rear of the cable tie plate 5, the design of the cable tie plate 5, cable management racks 6 and pressure plates 11 in the inner cavity of the cabinet 1 allows the cables in the upper and lower parts of the cabinet 1 to be staggered into outer and inner layers, avoiding the cables from crossing together. At the same time, it does not obstruct the termination box, thereby optimizing the utilization of the cabinet space and reducing signal interference, and facilitating the maintenance and management of the cables. After the construction is completed, the upper threshold 3 and lower threshold 4 can be restored, effectively improving the applicability of the termination cabinet.
