[0002] The leaky coaxial cable is a kind of cable with signal transmission function and antenna function. Through the control of the opening of the outer conductor, the controlled electromagnetic wave energy can be uniformly radiated along the line and received, so as to realize the coverage of the electromagnetic field blind area and achieve the purpose of smooth mobile communication. The leaky coaxial cable has two important indicators: transmission attenuation and coupling loss. The system loss of the leaky coaxial cable is the sum of the transmission attenuation and the coupling loss.

DETAILED DESCRIPTION
[0031] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application, i.e., the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0032] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application. It should be noted that the relational terms such as "first" and "second" and the like are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations.
[0033] Moreover, the term "comprising", "containing" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a list of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent in such a process, method, article or apparatus. Without more limitations, the element defined by the phrase "comprising a" does not exclude the presence of additional identical elements in the process, method, article or apparatus that includes the element.
[0034] As shown in Figure 1 An all-band gradual change type radiating leaky coaxial cable, in the overall structure, includes an inner conductor 1, the outer wall of the inner conductor 1 is attached with an insulating layer 11 for insulation, the outer wall of the insulating layer 11 is sleeved with an outer conductor 12, the outer wall of the outer conductor 12 is attached with a protective sleeve 13 for insulating protection of the outer conductor 12; the outer wall of the outer conductor 12 is divided into a plurality of groove segments, each groove segment sequentially increases the groove segment distance by a fixed increment, and the plurality of groove segments all adopt an eight-shaped segmented slot structure. At the same time, the eight-shaped segmented slot structure of each groove segment provided on the outer wall of the outer conductor 12 is symmetrically divided into 2 groups, 4 slot holes are arranged in each group, each slot hole is divided into two by a segmented type to form a segmented slot hole; the slot holes in a single group of the eight-shaped segmented slot structure sequentially increase the slot hole distance by a fixed increment.
[0035] Further, the present application is a new all-band gradual change type leaky radiation cable, as shown in Figure 1 and Figure 2As shown, the slot holes of each slot segment of the outer conductor 12 adopt a tapered design method, which is a full-band tapered slot hole layout design method. In implementation, the slot hole is designed in a segmented eight-shaped slot hole structure, and the slot hole pitch interval is arranged according to the actual situation and the design ratio. In the operation and production process, the slot hole length and pitch of the transmitting end of the leaky coaxial cable are designed, and the slot hole length and pitch size of the receiving end are set. According to the length to be produced, the number of each slot segment, i.e. the number of pitches, is calculated, and the slot hole is produced with a certain increment. For example, the hole length of the transmitting end is 12 mm and the pitch is 240 mm, and the calculated hole length and pitch increment is 0.02 and 0.01. After the first group of slot segments is carved by the slot carving equipment, the second group of slot segments 12.02 mm and 240.01 mm is executed, and the slot carving equipment is executed until the last group of slot segments is completed. The purpose of this design is to expand the frequency used by the leaky cable to a wider range.
[0036] Furthermore, the eight-shaped segmented slot hole structure of each slot segment provided on the outer wall of the outer conductor 12 is symmetrically divided into two groups, each group is provided with four slot holes, each slot hole adopts a segmented slot hole, and each group is divided into eight slot holes by dividing each slot hole into two parts. Eight slot holes are symmetrically arranged in one pitch (slot segment), and sixteen slot holes are arranged in one pitch. One segmented slot hole in each group can be used as shown in the figure, or each slot hole can be treated by staggered processing according to the size of the hole width. The angle of the slot hole can be adjusted to optimize the performance indicators such as attenuation and coupling loss.
[0037] In implementation, the frequency band is designed according to the signal transmitting end pitch P1=P11+P12 and the signal receiving end P2=P21+P22 length.
[0038] As shown in Figure 1 each slot hole in each group of the eight-shaped segmented slot hole structure of each slot segment of the transmitting end has a segmented pitch L11, and each slot hole has a length L12. In the two groups of the eight-shaped segmented slot hole structure of the transmitting end slot segment, the center of the gap between the first slot hole of one group and the center of the gap between the first slot hole of the other group has a distance P11. The center of the gap between the first slot hole of one group of the eight-shaped segmented slot hole structure close to the adjacent eight-shaped segmented slot hole structure of the transmitting end and the center of the gap between the first slot hole of one group of the eight-shaped segmented slot hole structure of the adjacent slot segment of the transmitting end has a distance P12. The center of the gap between the first slot hole of one group of the eight-shaped segmented slot hole structure of the transmitting end and the center of the gap between the first slot hole of one group of the eight-shaped segmented slot hole structure of the adjacent slot segment of the transmitting end has a distance P1.
[0039] As shown in Figure 2As shown, the segment distance of each slot hole in each group of the eight-shaped segmented slot hole structure of each slot section of the receiving end is L21, and the length of each slot hole is L22; the distance between the center of the gap between the first slot hole of one group and the center of the gap between the first slot hole of the other group in the eight-shaped segmented slot hole structure of the slot section of the receiving end is P21, the distance between the center of the gap between the first slot hole of one group close to the adjacent eight-shaped segmented slot hole structure and the center of the gap between the first slot hole of one group of the eight-shaped segmented slot hole structure of the adjacent slot section of the receiving end is P22, and the distance between the center of the gap between the first slot hole of one group of the eight-shaped segmented slot hole structure of the slot section of the receiving end and the center of the gap between the first slot hole of one group of the eight-shaped segmented slot hole structure of the adjacent slot section of the receiving end is P2;
[0040] P1 is the pitch of the slot hole of the transmitting end, P2 is the pitch of the receiving end, P1 and P2 have infinite pitches (P...) composed of each equal pitch, P1=P...=P2, or the slot hole layout can be performed according to the designed resonance frequency, P1P...P2, but it cannot affect the use frequency (but the minimum value of P1 and the maximum value of P2 must be determined). The leaky coaxial cable in a section, the front end and the tail end of the cable are composed of different pitches and hole lengths, the pitch P1 is the minimum value of the design, P2 is the maximum value of the design, the pitch increases with the length of the cable, and the length of the slot hole also increases with the length of the cable. In the figure, L11 and L21 refer to the interval after the slot hole is segmented, the interval point width cannot be less than 2mm, and through segmentation, the frequency that can be used is higher and higher, thereby keeping the high frequency point of 3700 more stable, and at the same time, it also plays a role of slot hole support in the production process, and the slot hole is not easy to be damaged by external force. In order to reduce the deformation of the slot hole caused by longitudinal packaging in the production process, the slot hole is treated by adopting the way of inverted half-angle slot hole chamfering. The attenuation and coupling loss of the leaky radiation cable are mainly realized by adjusting the length of L12 and L22, when L11 and L21 are constant, the smaller L12 and L22 are, the better the attenuation is, but the coupling loss is larger, and vice versa; in order to make the frequency used wider, P1 and P2 will fluctuate within the range allowed in the design, so as to have the characteristics of low attenuation, low coupling loss and wide frequency range. By adopting the gradual slot hole design, the outer conductor 12 of the leaky radiation cable is engraved into the required eight-shaped segmented slot hole structure by using the slotting equipment in the production process, and the leaky radiation cable produced by adjusting and controlling the slotting equipment can achieve the purpose of expanding the use frequency band of the leaky cable when suppressing part or all of the high-order mode spatial harmonics in the-1 mode radiation area, and the effect is relatively obvious. The slot hole of the leaky radiation cable produced by this method and equipment design has a large radiation angle, a strong signal, and is less affected by the laying environment. It can meet the use of 700-3700MHz frequency range. It can be used for radiation leaky coaxial cable products including 1 / 2 7 / 8 1-1 / 4 1-5 / 8, etc. It is suitable for rail transit public network and indoor distribution system (including 2G network, 3G network, 4G network, 5G network), and has wide application scenarios.
[0041] Further, in order to produce the leaky radiation cable, a slotting equipment for engraving the outer conductor 12 of the leaky radiation cable into the required design structure is specially designed, such as Figure 4 and as Figure 5As shown, the groove setting is designed to include a channel mechanism arranged on the support platform frame and used for the leakage coaxial cable to pass through, one end of the channel mechanism is provided with a limiting movable mechanism, and the end of the limiting movable mechanism away from the channel mechanism is provided with a groove mechanism used for grooving the outer conductor of the leakage coaxial cable. In the implementation process, by passing the outer conductor 12 of the leakage coaxial cable from the channel mechanism, the channel mechanism positions the leakage coaxial cable, so that the outer conductor 12 of the leakage coaxial cable enters the limiting movable mechanism, and is further limited and adjusted by the limiting movable mechanism, so that the outer conductor 12 of the leakage coaxial cable stably and accurately enters the groove mechanism, and the outer conductor 12 of the leakage coaxial cable is engraved into a structure shape required by design by controlling and adjusting the groove mechanism.
[0042] In the implementation, first, the outer conductor 12 of the leakage coaxial cable to be engraved is passed from the channel mechanism of the device, so that the outer conductor 12 of the leakage coaxial cable enters the device. The channel mechanism of the device includes a channel pipe 21 fixed at one end of the top surface of the support platform frame. One end of the leakage coaxial cable (at this time, the leakage coaxial cable is provided with the outer conductor 12) enters from the side wall end of the channel pipe 21 close to the support platform frame, and passes out from the other end of the channel pipe 21 and enters the limiting conical sleeve 22 arranged away from the side wall end of the channel pipe 21, which is fixed on the side of the support platform frame away from the channel pipe 21. At the same time, the limiting conical sleeve 22 is arranged with the small end of the cross section in the channel pipe 21, and the leakage coaxial cable passes through the channel pipe 21 and enters from the small end of the limiting conical sleeve 22 and passes out from the other end of the limiting conical sleeve 22. The leakage coaxial cable provided with the outer conductor 12 passes through the channel pipe 21 and enters the limiting conical sleeve 22. Under the limiting action of the channel pipe 21 and the limiting conical sleeve 22, the end of the limiting conical sleeve 22 away from the channel pipe 21 is symmetrically provided with a limiting clamping piece 23. The pair of movable clamping pieces 23 have a certain movable clamping function for the leakage coaxial cable passing therethrough, and the leakage coaxial cable is movably limited to smoothly pass through the pair of limiting clamping pieces 23 and smoothly enter the limiting movable mechanism.

The leaky coaxial cable passes through between the first transmission belt 313 and the second transmission belt 323, and then the second transmission belt 323 is driven by the adjusting activity support 31 to move towards the first transmission belt 313, so as to limit the leaky coaxial cable passing through between the first transmission belt 313 and the second transmission belt 323 between the first transmission belt 313 and the second transmission belt 323. At this time, the second transmission belt 323 is driven to rotate by the driving device on the activity support for driving the second transmission main shaft 321 to rotate, and the leaky coaxial cable is pulled into the next device process by the rotation of the first transmission belt 313.In order to realize the activity support activity, when setting, the activity support is provided with the movable table 31, the second transmission main shaft 321 is rotatably connected with the movable table 31 through the rotating shaft, the second transmission slave shaft 322 is rotatably connected with the movable table 31 through the rotating shaft, the second transmission main shaft 321 is provided with the driving motor at one end close to the movable table 31, the output shaft of the driving motor is connected with the second transmission main shaft 321, for driving the second transmission main shaft 321 to rotate, the driving motor is fixed on the movable table 31, the movable table 31 is slidably arranged on the side of the support platform frame away from the channel pipeline 21 through the movable guide rail, so that the movable table 31 of the activity support can move along the top surface of the support platform frame, and the driving motor fixed on the movable table 31 drives the second transmission main shaft 321 to rotate, thereby driving the second transmission slave shaft 322 connected with the second transmission main shaft 321 to move, and further realizing that the leak coaxial cable is clamped and limited between the first transmission belt 313 and the second transmission belt 323, while the first transmission belt 313 and the second transmission belt 323 (the first transmission belt 313 and the second transmission belt 323 can be rotatably arranged between the second transmission main shaft 321 and the first transmission main shaft 311 through friction or gear meshing, or through friction between the two) pull the leak coaxial cable sleeved with the outer conductor 12 to move forward. In order to facilitate the movement control of the activity support, the movable rotating wheel 33 for conveniently driving the movable table 31 to translate along the top surface of the support platform frame is arranged at the side wall end of the movable table 31 close to the support platform frame, one end of the movable rotating wheel 33 is connected with the connecting shaft, one end of the connecting shaft is rotatably connected with the side wall of the movable table 31 through the bearing, and the support plate is fixed on the top surface of the support platform frame; when adjusting and controlling, the movable rotating wheel 33 is held by hand, and the movable rotating wheel 33 is rotated by force, the movable rotating wheel 33 is connected with the support plate through the connecting shaft and the support plate in screw connection along the support plate connected with the top surface of the support platform frame, thereby the movable rotating wheel 33 rotates, drives the connecting shaft connected with one end surface of the movable rotating wheel 33 to rotate through the bearing connecting of the movable table 31 to translate along the top surface of the support platform frame, realizes the movable limiting of the leak coaxial cable sleeved with the outer conductor 12 passing between the first transmission belt 313 and the second transmission belt 323, and drives the leak coaxial cable sleeved with the outer conductor 12 to move forward, so that the leak coaxial cable sleeved with the outer conductor 12 enters the limiting structure, and the limiting structure is used for limiting and guiding the leak coaxial cable sleeved with the outer conductor 12.
[0044] And, the limiting structure comprises symmetrically arranged positioning support frames, and a rolling support wheel 34 is arranged between the two positioning support frames, the rolling support wheel 34 is fixed on the support platform frame through a rotating shaft, the leak coaxial cable enters from the positioning support frame close to the first conveying belt 313 and the second conveying belt 323, passes through the rolling support wheel 34, and exits from the positioning support frame away from the first conveying belt 313 and the second conveying belt 323 and enters the grooving mechanism.
