All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0032] Example 1

[0033] Please refer to Figure 1-Figure 4As shown, the first embodiment of the present invention provides a lightning protection distribution cabinet 10, which can be used for railway signal transmission. Cables can be inserted into the lightning protection distribution cabinet 10 and laid. The cables are mainly divided into indoor cables 20 and trackside cables 30.

[0034] The lightning protection distribution cabinet 10 is mainly composed of a cabinet body 11 and a mounting plate 12 . The mounting plate 12 is arranged in the cabinet body 11 . Each component is discussed in detail below.

[0035] The structure of the cabinet 11 is not limited and can refer to the existing technology. The cabinet 11 forms a receiving cavity, and one side of the cabinet 11 can be open and provided with a cabinet door.

[0036] The mounting plate 12 is a plate-shaped structure, and the style of the mounting plate 12 can refer to the existing technology.

[0037] The mounting plate 12 is provided with a lightning protection unit 120 and a transverse wire duct 121. The number of the lightning protection unit 120 and the transverse wire duct 121 can be set as needed. In this embodiment, the lightning protection modules are evenly distributed in the form of m rows and n columns. A transverse wire duct 121 is provided between two adjacent rows of lightning protection modules. The structure of the transverse wire duct 121 can refer to the prior art.

[0038] The mounting plate 12 divides the cabinet 11 into two wiring areas 110, one of which is located on the front of the mounting plate 12, and the other is located on the back of the mounting plate 12.

[0039] The two wiring areas 110 are each provided with a cable entry port, through which indoor cables 20 or trackside cables 30 can enter the wiring area 110. It should be noted that a lightning protection distribution cabinet 10 needs to accommodate both indoor cables 20 and trackside cables 30. The indoor cables 20 and trackside cables 30 need to enter the cabinet through different cable entry ports, and they are physically isolated from each other to prevent mutual interference.

[0040] In this embodiment, the cable inlet on the front of the mounting plate 12 is an indoor cable inlet 111, and the cable inlet on the back of the mounting plate 12 is a trackside cable inlet 112. Generally speaking, the width of the wiring area 110 on the back of the mounting plate 12 is generally greater than the width of the wiring area 110 on the front of the mounting plate 12. Since the trackside cables 30 are relatively thick, this arrangement maximizes the use of space within the cabinet 11 and saves costs.

[0041] The cable entry can be located on the top of the cabinet 11 or on the top of the cabinet 11. This arrangement can hide the cables as much as possible and prevent them from being damaged. Of course, in some embodiments, the cable entry can also be located on the side wall of the cabinet 11. The style and size of the cable entry are not limited and can be set as needed.

[0042] The number of cable entry ports can be set as needed. In this embodiment, cable entry ports are respectively provided at the left and right ends of the wiring area 110 .

[0043] In this embodiment, please combine Figure 2-Figure 5 As shown, a transverse wire duct 121 is provided on the back of the mounting plate 12. The mounting plate 12 is provided with a plurality of wire holes 115. The two wiring areas 110 are connected through the wire holes 115. The number and position of the wire holes 115 are not limited and can be set as needed. For example, the wire holes 115 can be provided at one or both ends of the adjacent transverse wire duct 121. The cables located on the back of the mounting plate 12 can directly enter the corresponding transverse wire duct 121, while the cables located on the front of the mounting plate 12 need to pass through the wire holes 115 to reach the back of the mounting plate 12 and enter the corresponding transverse wire duct 121. In other embodiments, some or all of the transverse wire ducts 121 can also be provided on the front of the mounting plate 12.

[0044] Several horizontal cable ducts 121 are divided into indoor cable ducts 122 and trackside cable ducts 123. The indoor cable ducts 122 can lay indoor cables 20, and the trackside cable ducts 123 can lay trackside cables 30. The indoor cable ducts 122 and the trackside cable ducts 123 are arranged alternately. Each row of lightning protection units 120 is correspondingly provided with indoor cable ducts 122 and trackside cable ducts 123, and each horizontal cable duct 121 is matched with two adjacent rows of lightning protection units 120.

[0045] In addition, in order to make the cable wiring in the cabinet 11 more neat and convenient for installation and maintenance, in this embodiment, the following solutions can also be adopted but are not limited to: Figure 6 As shown, a cable fixing channel 113 is provided in the wiring area 110. The cable fixing channel 113 can be provided on the inner surface of the cabinet 11. The cable fixing channel 113 extends vertically, and the cable inlet and the transverse cable duct 121 are connected through the cable fixing channel 113. After the cable enters the cabinet 11 through the cable inlet, it passes through the cable fixing channel 113 and reaches the transverse cable duct 121. Of course, in some embodiments, the cable fixing channel 113 can also be omitted.

[0046] The style of the wire channel 113 is not limited. For example, a cover is provided in the wiring channel, and the cover is fixed to the cabinet 11 or the mounting plate 12. The wire channel 113 is formed between the cover and the cabinet 11. One end of the cover is adjacent to the cable entry port, and the cover has a wiring opening adjacent to the corresponding transverse wire duct 121. In this embodiment, the structure of the wire channel 113 can also adopt the following technical solution: a plurality of wire fixing components 114 are provided on the inner side wall of the cabinet 11. The wire fixing components 114 are connected to the cabinet 11 or the wire fixing components 114 are connected to the mounting plate 12. The number of wire fixing components 114 can be set as needed. The plurality of wire fixing components 114 are arranged at intervals to form the wire channel 113, that is, the wire channel 113 is intermittently distributed. The cables entering the cabinet 11 from the cable entry port pass through the plurality of wire fixing components 114 in sequence and reach the corresponding transverse wire duct 121.

[0047] The structure of the wire fixing assembly 114 can refer to the existing technology. In this embodiment, the wire fixing assembly 114 includes a plurality of sub-channels. The number of sub-channels can be set as needed. The plurality of sub-channels are stacked in sequence. The sub-channels are in the shape of long strips. Cables entering from the same cable inlet can be arranged in different sub-channels respectively. A row of cables can be arranged in each sub-channel. Specifically, the wire fixing assembly 114 includes a wire fixing member and a plurality of fixing strips. The wire fixing member is connected to the cabinet 11. The wire fixing member is arranged in a U-shape, and a wire fixing area is formed inside. The fixing strips are in the shape of long strips and extend across the wire fixing member. The fixing strips are arranged at intervals. The fixing strips are fixedly connected to the wire fixing member or detachably connected. The adjacent two fixing strips and the wire fixing member form a sub-channel. Of course, in some embodiments, the fixing strips can also be replaced with a plate-like structure of a wire fixing plate.

[0048] For parts not mentioned in this embodiment, reference can be made to the prior art.

[0049] The method of using the lightning protection distribution cabinet 10 provided in this embodiment is as follows: the indoor cable 20 and the trackside cable 30 enter the cabinet body 11 through different cable inlets respectively, and the cables are laid upward or downward along the fixed line channel 113. When the cables reach the corresponding height, they branch into the horizontal cable duct 121. At this time, the cables located on the back of the mounting plate 12 can directly enter the horizontal cable duct 121, and the cables located on the front of the mounting plate 12 can reach the back of the mounting plate 12 through the wire hole 115 and enter the horizontal cable duct 121.

[0050] Of course, the above methods can be added, subtracted, modified or adjusted in order as needed.

[0051] Example 2

[0052] Please refer to Figure 7-10 As shown, the second embodiment of the present invention provides a lightning protection distribution cabinet 10. The difference between this embodiment and the first embodiment lies in the different arrangement of the cable entry port.

[0053] Specifically, in this embodiment, the cable inlets located on both sides of the mounting plate 12 include an indoor cable inlet 111 and a trackside cable inlet 112, that is: the front of the mounting plate 12 has an indoor cable inlet 111 and a trackside cable inlet 112, and the two are located at the left and right ends of the inner side of the cabinet 11; the back of the mounting plate 12 has an indoor cable inlet 111 and a trackside cable inlet 112, and the two are located at the left and right ends of the inner side of the cabinet 11.

[0054] Furthermore, in this embodiment, the indoor cable entry openings 111 in the two wiring areas 110 are adjacent to each other, and the trackside cable entry openings 112 in the two wiring areas 110 are adjacent to each other. This arrangement provides a greater separation between the indoor cables 20 and the trackside cables 30, preventing them from interfering with each other. Of course, in some embodiments, the indoor cable entry opening 111 in one wiring area 110 may be adjacent to the trackside cable entry opening 112 in another wiring area 110.

[0055] For parts not mentioned in this embodiment, reference may be made to the first embodiment or the prior art.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
