At the same time, because the high-frequency electromagnetic wave transmission signal is more complicated by the leakage of the coaxial cable structure and the environment, the design and manufacture of the product structure are difficult, and it has always been a high-tech product type in the field of coaxial cable production.
不同于天线的直线式、广范围覆盖，漏泄同轴电缆更利于在狭长、封闭环境中应用，如：地铁、隧道、山洞、矿井等区域。在当前移动通信技术进入5G时代，通信领域应用的新技术、新材料不断涌现，既带来产品性能要求的提高，也带来了产品工艺技术的变革。一方面，通信服务作为国家基础设施，与供水、供电一样正成为生活必需品，这就要求通信信号覆盖范围广、无盲区；另一方面，为了实现高速率、高带宽的信息传输，通信的频率在不断升高。而通信频率的提高带来了电磁信号空间传输衰减的增加、对建筑物穿透损耗的增加，提高了对狭长封闭区域的无线信号覆盖难度。当前现有的漏泄同轴电缆在5G移动通信的高频段使用时，纵向传输衰减与耦合损耗两个重要性能指标难以兼顾，无法同时达到传输距离和有效信号覆盖范围的需求。为此，需进行产品结构和生产方式的重新设计，以适应5G移动通信高速率、信号强、传输距离长的通信要求。Different from the linear, wide-area coverage of antennas, leaky coaxial cables are more suitable for applications in narrow, long, closed environments, such as subways, tunnels, caves, mines, and other areas. With the current mobile communication technology entering the 5G era, new technologies and new materials used in the communication field continue to emerge, which not only brings about the improvement of product performance requirements, but also brings about changes in product process technology. On the one hand, as a national infrastructure, communication services are becoming a necessities of life like water supply and power supply, which requires wide coverage of communication signals and no blind spots; on the other hand, in order to achieve high-speed, high-bandwidth information transmission, the frequency of continuously rising. The increase of communication frequency brings the increase of electromagnetic signal space transmission attenuation and the increase of building penetration loss, which increases the difficulty of wireless signal coverage in narrow and long closed areas. When the existing leaky coaxial cable is used in the high frequency band of 5G mobile communication, it is difficult to take into account the two important performance indicators of longitudinal transmission attenuation and coupling loss, and cannot meet the requirements of transmission distance and effective signal coverage at the same time. To this end, it is necessary to redesign the product structure and production method to meet the communication requirements of 5G mobile communication with high speed, strong signal and long transmission distance.

如图1至图2所示，在本实施例中，第一槽孔201及第二槽孔202是以节距P为周期在外导体2长度方向上分别进行排列。节距P可以根据空间谐波产生原理的公式进行计算：
Figure PCTCN2021140530-appb-000003
其中：P为第一槽孔或第二槽孔的周期性节距，C为光在真 空中的传播速度，f 1为适用于5G通信的漏泄同轴电缆组件工作频带范围内最低工作频率，ε γ为绝缘层相对介电常数，约为1.22，同时为抑制漏泄同轴电缆线组件产生的高次空间谐波，需在适用于5G通信的漏泄同轴电缆组件的节距P范围内开一系列相同的长方形槽孔，一个周期内第一槽孔或第二槽孔的中心间距P n可根据下式计算；P n＝P/(2(n+1))，其中：P为周期性节距，n为从1开始的正整数，代表第n+1次空间谐波。假设漏泄同轴电缆线组件工作频率范围为2500MHz～3600MHz，最低工作频率为2500MHz，其对应的波长为120mm，此时计算得出节距P约为57.3mm。因此，节距P的大小约为适用于5G通信的漏泄同轴电缆组件工作频带范围内最低工作频率对应的波长的二分之一。一系列周期相邻的第一槽孔201或第二槽孔202的中心间距P n如下： As shown in FIG. 1 to FIG. 2 , in this embodiment, the first slot holes 201 and the second slot holes 202 are respectively arranged in the longitudinal direction of the outer conductor 2 with the pitch P as the period. The pitch P can be calculated according to the formula of the principle of space harmonic generation:
Figure PCTCN2021140530-appb-000003
Where: P is the periodic pitch of the first slot hole or the second slot hole, C is the propagation speed of light in vacuum, f 1 is the minimum operating frequency within the operating frequency band of the leaky coaxial cable assembly suitable for 5G communication, ε γ is the relative dielectric constant of the insulating layer, which is about 1.22. At the same time, in order to suppress the high-order space harmonics generated by the leaky coaxial cable assembly, it needs to be opened within the pitch P range of the leaky coaxial cable assembly suitable for 5G communication. For a series of identical rectangular slot holes, the center distance P n of the first slot hole or the second slot hole in one cycle can be calculated according to the following formula; P n =P/(2(n+1)), where: P is the period Pitch, n is a positive integer starting from 1, representing the n+1th spatial harmonic. Assuming that the operating frequency range of the leaky coaxial cable assembly is 2500MHz to 3600MHz, the minimum operating frequency is 2500MHz, and the corresponding wavelength is 120mm. At this time, the calculated pitch P is about 57.3mm. Therefore, the size of the pitch P is about one-half of the wavelength corresponding to the lowest operating frequency in the operating frequency band of the leaky coaxial cable assembly suitable for 5G communication. The center-to-center spacing P n of a series of periodically adjacent first slot holes 201 or second slot holes 202 is as follows:
单周期内的槽孔数量Number of slots in a single cycle 11 22 33 44
槽孔间的中心间距(mm)Center distance between slots (mm) ———— 28.628.6 14.314.3 9.59.5
由此可知，单周期内第一槽孔201或第二槽孔202的数量越多，中心间距越小。It can be seen from this that the greater the number of the first slot holes 201 or the second slot holes 202 in a single cycle, the smaller the center-to-center distance.
如图4所示，本发明还提供了适用于5G通信的漏泄同轴电缆组件的制造方法，包括以下步骤:As shown in Figure 4, the present invention also provides a method for manufacturing a leaky coaxial cable assembly suitable for 5G communication, comprising the following steps:

S2：在“8”字形排列的两根绝缘缆芯外表面涂覆化学药剂，并将外导体以纵包的方式粘覆在化学药剂上使两根绝缘缆芯形成一体，并在外导体上开设若干第一槽孔及第二槽孔，第一槽孔和第二槽孔成对设置，第一槽孔及第二槽孔正交设置；S2: Coat chemical agents on the outer surfaces of the two insulated cable cores arranged in the "8" shape, and stick the outer conductors on the chemical agents in a longitudinally wrapping manner to form a whole of the two insulated cable cores, and open the outer conductors. a plurality of first slot holes and second slot holes, the first slot holes and the second slot holes are arranged in pairs, and the first slot holes and the second slot holes are arranged orthogonally;
S3：调整所述外导体的位置，使得所述第一槽孔及所述第二槽孔分别同时对准所述两根绝缘缆芯的同侧，且每对所述第一槽孔的中心点与所述第二槽孔的中心点构成平面A，所述平面A与所述第一方向所在的水平面B垂直；S3: Adjust the position of the outer conductor so that the first slot hole and the second slot hole are aligned with the same side of the two insulating cable cores at the same time, and the center of each pair of the first slot holes The point and the center point of the second slot form a plane A, and the plane A is perpendicular to the horizontal plane B where the first direction is located;
S4：在外导体外侧套上护套层以将外导体收紧固定在两根绝缘缆芯上。S4: Cover the outer side of the outer conductor with a sheath layer to tighten and fix the outer conductor on the two insulated cable cores.
需要说明的是，步骤S1中规格相同的两根绝缘缆芯可以通过将同一根绝缘缆芯裁剪而成，也可以是同批次、同工艺、同设备生产的两根同规格的绝缘缆芯，这样可以实现两根绝缘缆芯在信号传输路径上，同一位置的辐射电磁波信号的场强大小基本相同。步骤S2中外导体选用双层铜塑复合膜，即包括两铜层及一塑料层，两根绝缘缆芯分别放置在双层铜塑复合膜的两侧(如图5所示)，然后采用渐近式的成形模及喇叭型模的方式逐步收紧，将铜塑复合膜的铜层及塑料层分别纵包在两根绝缘缆芯的外表面上，两铜层分别设有第一槽孔及第二槽孔。本方法可以实现两根绝缘缆芯在信号传输路径上， 同一位置的辐射电磁波信号正交叠加。步骤S3中对第一槽孔及第二槽孔的朝向进行微调，可以实现适用于5G通信的漏泄同轴电缆组件辐射出的叠加的电磁波信号中，两个互相垂直的线极化波E x和E y的大小基本相同，当极化轴比(辐射场的瞬时最大值与最小值之比)小于3dB时，可实现圆极化工作模式，此时，辐射场强以圆极化方式工作的适用于5G通信的漏泄同轴电缆组件可以最大程度上收发不同极化方向的信号，进一步增强信号的覆盖能力。 It should be noted that the two insulated cable cores with the same specifications in step S1 can be cut from the same insulated cable core, or they can be two insulated cable cores of the same specification produced in the same batch, the same process, and the same equipment. , so that the two insulated cable cores are on the signal transmission path, and the field strength of the radiated electromagnetic wave signal at the same position is basically the same. In step S2, the outer conductor adopts a double-layer copper-plastic composite film, that is, it includes two copper layers and a plastic layer, and the two insulating cable cores are placed on both sides of the double-layer copper-plastic composite film (as shown in The method of the near-type forming mold and the horn-shaped mold is gradually tightened, and the copper layer and the plastic layer of the copper-plastic composite film are longitudinally wrapped on the outer surfaces of the two insulating cable cores, and the two copper layers are respectively provided with a first slot hole. and the second slot. The method can realize the orthogonal superposition of radiated electromagnetic wave signals at the same position with two insulated cable cores on the signal transmission path. In step S3, the orientations of the first slot hole and the second slot hole are fine-tuned, so that in the superimposed electromagnetic wave signal radiated by the leaky coaxial cable assembly suitable for 5G communication, two mutually perpendicular linearly polarized waves E x can be realized. The size of E y is basically the same. When the polarization axis ratio (the ratio of the instantaneous maximum value to the minimum value of the radiation field) is less than 3dB, the circular polarization working mode can be realized. At this time, the radiation field intensity works in a circular polarization mode. The leaky coaxial cable assembly suitable for 5G communication can transmit and receive signals in different polarization directions to the greatest extent, further enhancing the coverage of the signal.
综上所述，本发明提供了适用于5G通信的漏泄同轴电缆组件及其制造方法，将两根绝缘缆芯通过同一外导体包覆实现漏泄同轴电缆以组件形式传输，一方面可以增强信号覆盖强度，另一方面有效减少了单根漏泄同轴电缆外导体上槽孔数量，降低了单根漏泄同轴电缆的能量泄露及纵向传输衰减值，提高了漏泄同轴电缆线组件的传输距离，从而降低整体覆盖系统中的中继设备成本、前期敷设和后期维护成本。To sum up, the present invention provides a leaky coaxial cable assembly suitable for 5G communication and a manufacturing method thereof. The two insulated cable cores are covered by the same outer conductor to realize the transmission of the leaky coaxial cable in the form of an assembly. On the one hand, it can enhance the The signal coverage strength, on the other hand, effectively reduces the number of slots on the outer conductor of a single leaky coaxial cable, reduces the energy leakage and longitudinal transmission attenuation value of a single leaky coaxial cable, and improves the transmission of the leaky coaxial cable assembly. distance, thereby reducing the cost of relay equipment, pre-laying and post-maintenance costs in the overall coverage system.
通过设置外导体上的第一槽孔及第二槽孔分别与第一方向呈-45°与45°的长方形槽孔，且空间位置对齐，可以使得适用于5G通信的漏泄同轴电缆组件中辐射的电磁波可以正交叠加，消除两根漏泄同轴电缆间的信号干扰，增强信号的相干增益。同时，两根绝缘缆芯采用同规格的绝缘缆芯，这样既可以保证适用于5G通信的漏泄同轴电缆组件中传输的电磁信号能量强度保持均匀一致，也可实现辐射电磁信号的正交叠加，且当极化轴比小于3dB时形成圆极化信号覆盖，极大的增强了信号覆盖强度。By arranging the first slot hole and the second slot hole on the outer conductor with rectangular slots at -45° and 45° respectively with respect to the first direction, and the spatial positions are aligned, it is possible to make the leaky coaxial cable assembly suitable for 5G communication. The radiated electromagnetic waves can be orthogonally superimposed, eliminating the signal interference between the two leaky coaxial cables and enhancing the coherence gain of the signal. At the same time, the two insulated cable cores are of the same specification, which can not only ensure that the energy intensity of electromagnetic signals transmitted in the leaky coaxial cable assembly suitable for 5G communication remains uniform, but also realize the orthogonal superposition of radiated electromagnetic signals. , and when the polarization axis ratio is less than 3dB, circularly polarized signal coverage is formed, which greatly enhances the signal coverage strength.
外导体以双层铜塑复合膜代替了传统的铜箔带，可以减少外导体铜材的消耗，降低了生产成本，并且采用一体化纵包粘附铜塑复合膜的方式生产，代替了传统铜箔带上先冲槽孔，再轧纹，然后纵包的方式，可以一次性完成两根漏泄同轴电缆的生产，并直接构成适用于5G通信的漏泄同轴电缆组件，简化了生产步骤。The outer conductor is replaced by a double-layer copper-plastic composite film instead of the traditional copper foil tape, which can reduce the consumption of copper material of the outer conductor and reduce the production cost. The copper foil tape is punched first, then embossed, and then longitudinally wrapped, which can complete the production of two leaky coaxial cables at one time, and directly form a leaky coaxial cable assembly suitable for 5G communication, which simplifies the production steps. .
适用于5G通信的漏泄同轴电缆组件的使用，避免了传统上需两根漏泄同轴电缆分别进行布放，可以一次施工布放就解决安装问题，且适用于5G通信的漏泄同轴电缆组件的外导体第一槽孔及第二槽孔位置相对固定，实现了第一槽孔及第二槽孔与信号覆盖区域正对，提高了施工效率，且由于原材料使用的减少，适用于5G通信的漏泄同轴电缆组件整体重量减轻，方便了布放施工，也节约了布放空间。The use of leaky coaxial cable assemblies suitable for 5G communication avoids the traditional need for two leaky coaxial cables to be laid separately, which can solve the installation problem in one construction and deployment, and is suitable for leaky coaxial cable assemblies for 5G communication. The positions of the first slot hole and the second slot hole of the outer conductor are relatively fixed, so that the first slot hole and the second slot hole are directly opposite to the signal coverage area, which improves the construction efficiency, and is suitable for 5G communication due to the reduction in the use of raw materials. The overall weight of the leaky coaxial cable assembly is reduced, which facilitates the deployment and construction and saves the deployment space.
