Description
技术领域 本发明涉及电子设备线路的接插件，特别涉及同轴连接器。Technical Field The present invention relates to connectors for electronic equipment circuits, in particular to coaxial connectors.
背景技术 目前国际上推出的同轴连接器品种很多，例如1.85mm、2.4mm、K型(2.92mm)、3.5mm、BNC、TNC、SMA、SMP、SMB、MCX、BMA型连接器等等。在这些连接器中，1.85mm、2.4mm、K型(2.92mm)、3.5mm、N型连接器等采用空气介质，SMA、BNC、SMB、MCX等采用聚四氟乙烯介质。其中采用聚四氟乙烯介质的连接器由于材料机械强度低，单靠聚四氟乙烯介质本身难以固定连接器的内外导体。一般通行的做法是在适当的位置开孔，从孔中注入胶粘剂，用以固定内外导体，由于胶粘剂的引入，容易导致介质材料的介电常数突变，导致连接器电气性能变差，同时外导体上注胶孔的开设，会导致连接器的电磁泄露增大，影响信号传输的质量。因此，如何能取消注胶孔和胶粘剂的使用，一直是业界致力于解决的一个比较困难的问题。Background Art Currently, there are many types of coaxial connectors introduced internationally, such as 1.85mm, 2.4mm, K-type (2.92mm), 3.5mm, BNC, TNC, SMA, SMP, SMB, MCX, BMA-type connectors and so on. Among these connectors, 1.85mm, 2.4mm, K-type (2.92mm), 3.5mm, and N-type connectors use air media, and SMA, BNC, SMB, MCX, etc. use polytetrafluoroethylene media. Among them, the connector using polytetrafluoroethylene medium has low mechanical strength of the material, and it is difficult to fix the inner and outer conductors of the connector only by the polytetrafluoroethylene medium itself. The general practice is to open holes at appropriate positions and inject adhesive from the holes to fix the inner and outer conductors. Due to the introduction of adhesives, it is easy to cause a sudden change in the dielectric constant of the dielectric material, resulting in poor electrical performance of the connector. At the same time, the outer conductor The opening of the upper glue injection hole will increase the electromagnetic leakage of the connector and affect the quality of signal transmission. Therefore, how to eliminate the use of glue injection holes and adhesives has always been a relatively difficult problem that the industry is committed to solving.
发明内容 本发明的目的是提供一种复合介质支撑同轴连接器，这种连接器有效降低了介质材料介电常数突变的影响，并可使连接器的电磁泄漏减小。SUMMARY OF THE INVENTION The object of the present invention is to provide a composite dielectric support coaxial connector, which effectively reduces the impact of sudden changes in the dielectric constant of the dielectric material and reduces the electromagnetic leakage of the connector.
本发明的目的是通过以下技术方案来实现的：一种复合介质支撑同轴连接器，包括内导体、外导体和介质支撑。其特征是介质支撑由甲乙两种部件复合而成，其中甲部件的材质为聚四氟乙烯，乙部件的材质为机械强度高于聚四氟乙烯的介质材料，乙部件位于连接器的中央部位，甲部件位于乙部件的两侧或一侧。The purpose of the present invention is achieved through the following technical solutions: a composite dielectric support coaxial connector, including an inner conductor, an outer conductor and a dielectric support. It is characterized in that the dielectric support is composed of two parts, A and B. The material of part A is polytetrafluoroethylene, and the material of part B is a dielectric material with higher mechanical strength than polytetrafluoroethylene. Part B is located in the central part of the connector. , part A is located on both sides or one side of part B.
上述技术方案中所说的机械强度高于聚四氟乙烯的介质支撑材料是聚酰亚胺(PI)。The dielectric support material whose mechanical strength is higher than that of polytetrafluoroethylene mentioned in the above technical solution is polyimide (PI).
上述技术方案中所说的乙部件的形状为圆片状，圆片的两端有环行的补偿槽或补偿环，乙部件两侧的甲部件端面上有对应的补偿环或补偿槽。补偿环和补偿槽的设置是为了适用于复合介质支撑界面间的电气传输要求。The shape of part B mentioned in the above technical solution is disc shape, and there are circular compensating grooves or compensating rings at both ends of the disc, and there are corresponding compensating rings or compensating grooves on the end faces of part A on both sides of part B. The setting of the compensation ring and the compensation groove is to meet the electrical transmission requirements between the composite dielectric support interfaces.
上述技术方案中所说的外导体由互相套接在一起的两个部件组成，两部件之间通过过盈配合或螺纹连接。采用这种设计的出发点是便于装配，由于本发明的介质支撑是甲乙两个部件复合而成，单一部件的外导体将使同轴连接器的装配产生困难。The outer conductor mentioned in the above technical solution is composed of two parts that are nested together, and the two parts are connected by interference fit or thread. The starting point of adopting this design is to facilitate assembly. Since the dielectric support of the present invention is composed of two parts, A and B, the outer conductor of a single part will make the assembly of the coaxial connector difficult.
本发明适用于SMA、BNC、TNC、SMB、MCX等系列的同轴连接器，这些系列的同轴连接器的共同特点是采用聚四氟乙烯作为介质支撑材料。The present invention is applicable to series of coaxial connectors such as SMA, BNC, TNC, SMB, MCX, etc. The common feature of these series of coaxial connectors is that polytetrafluoroethylene is used as the medium supporting material.
采用这种技术方案的基本思路是：考虑到聚四氟乙烯的机械强度较低，取消胶粘剂后必须提高介质支撑的总体强度，复合材料的综合性能可以优于单一材料，如果选用适当的高机械强度材料与之复合使用，应该可以达到发明的目的。The basic idea of adopting this technical solution is: considering the low mechanical strength of PTFE, the overall strength of the medium support must be improved after removing the adhesive, and the overall performance of the composite material can be better than that of a single material. The composite use of strength material should be able to achieve the purpose of the invention.
试验证明，这种方案是可行的，达到了发明的预期效果。Tests have proved that this scheme is feasible and has achieved the expected effect of the invention.
这种复合介质支撑同轴连接器的优点是：一、取消了现有技术中使用的胶粘剂，而且两种介质的介电常数接近，从而有效降低了介质材料中介电常数发生突变的不利影响，有利于电气性能的改善；二、不需要在外导体上开注胶孔，从而消除了这个发生电磁泄漏的通道；三、与现有技术中开有胶孔的三维形体比较，对信号传输质量的影响较小；四、简化了加工和装配工艺。The advantages of this composite medium-supported coaxial connector are: 1. The adhesive used in the prior art is eliminated, and the dielectric constants of the two media are close, thereby effectively reducing the adverse effects of sudden changes in the dielectric constant in the dielectric material. It is conducive to the improvement of electrical performance; second, there is no need to open a glue hole on the outer conductor, thereby eliminating the channel for electromagnetic leakage; third, compared with the three-dimensional shape with glue holes in the prior art, the quality of signal transmission The impact is small; Fourth, the processing and assembly process is simplified.
