二、 背景技术: Second, the technical background:

'背景技术中,随着移动通信事业的快速发展,对功率容量大、低损耗、低交调的天、馈线缆的需求量也日益增大。 'Background art With the rapid development of mobile telecommunications industry, large power capacity, the demand for low loss, low crosstalk days, the feed cable is also increasing. 因此1/2"同轴电缆在信号传输系统中使用量与日倶增。同时天、馈系统的安装和调试均在野外进行,因此便于野外安装的连接器也是天、馈系统选用连接器时的首选。 Thus 1/2 "coaxial cable used in a signal transmission system and the amount of increasing Japanese Ju Meanwhile days, installation and commissioning of the feed system are carried out in the field, thus facilitating field installation of the connector is also the day, the feed connector system used choice.

目前1/2"同轴电缆可根据外导体的形状分为波纹管和光滑管两大类。但是由于不同电缆生产商所生产的1/2"波纹电缆尺寸都有所差异,而光滑管在外形上与波纹电缆更是有较大的不同。 Currently 1/2 "coaxial cable can be divided into the smooth tube and the bellows into two categories depending on the shape of the outer conductor. However, due to the different cable manufacturers 1/2 the production of" the difference in size of the cable has a corrugated, and smooth tubes the corrugated shape the cable is quite different. 因此,虽然都是l/2"的同轴电缆,但是由于电缆尺寸的差异和连接器结构限制,基本上不同生产商生产的电缆都需要有一种连接器与之对应。目前市场上还不存在可以同时配接光滑管和波纹管两种不同类型电缆的连接器。 Thus, although all l / 2 "coaxial cable, but due to the difference in size of the cable connector and structural constraints, is basically made by different manufacturers are required to have a cable connector corresponding thereto. Does not exist on the market mating connector simultaneously smooth and bellows two different types of cables.

L29、 N型连接器以其连接可靠(螺纹式连接)、结构坚固稳定、功率容量大、 耐高压、低损耗等优越特点而成为大功率容量、低损耗、低交调的天、馈线缆研制,开发时的首选界面。 L29, N-type connector with its reliable connection (screw connection), strong and stable structure, large power capacity, high pressure, low loss characteristics and excellent capacity for high-power, low loss, low crosstalk day, feed cable research and development at the interface of choice. 现有配接1/2"同轴电缆的L29型插针接触件射频同轴连接器,由于其内部结构复杂,组成部分繁多,零件的加工、装配难度大, 大批量生产时质量稳定性较差,这样不但使得连接器的生产成本增大,更不适合野外的安装和更换。 Mating conventional 1/2 "L29 pin contact type coaxial RF coaxial connectors, because of the complexity of its internal structure, the composition range, parts of the processing section, large assembly difficulty and quality stability of mass production than difference, so that not only increases the production cost of the connector, but not suitable for the field installation and replacement.

综上所述,目前配接1/2"同轴电缆的L29型插针接触件射频同轴连接器存在明显的不足。 In summary, there is now obvious shortcomings mating 1/2 "L29 coaxial pin contact type RF coaxial connectors.

五、具体实施方式: V. DETAILED DESCRIPTION:

参见图l,本发明包括相互连接的外导体4和外导体7,外导体4一侧为内导体2,内导体2与外导体4之间设置有作为内导体2主支撑的绝缘支撑件3, 内导体2尾部与外导体4之间设置有作为内导体2辅助支撑的绝缘支撑件6。 Referring to FIG. L, the present invention comprises an outer conductor 4 and the outer conductor 7 connected to each other, one side of the outer conductor 4 of the inner conductor 2 is provided with an insulating support member 2 as the main support of the inner conductor 3 4 between the inner conductor and the outer conductor 2 , 4 is provided between the inner conductor and the outer conductor tail portion 2 with an insulating supporting member inside a conductor 6 supported by the second auxiliary.

绝缘支撑件3为TPX绝缘支撑件,外导体7内部设置有一段圆弧,外导体4尾部设置有带有台阶的斜面。 TPX insulating support 3 for the insulating support member 7 inside the outer conductor is provided with a circular arc, the outer conductor 4 is provided with a tail of a stepped ramp.

参见图2和图3,本发明采用外导体7内部一段圆弧作为支撑,由于铝和铜都具有较好的延展性,电缆外导体翻开后紧贴在外导体7的圆弧上,由外导体4 尾部斜面和外导体7内部圆弧共同夹紧电缆外导体,无论是光面还是波纹电缆, 也不论电缆的外导体是铝质还是铜质的,都能顺利翻开贴合至圆弧面,有效解决了不同电缆无法采用同一零件夹紧外导体的难题。 Referring to FIGS. 2 and 3, the present invention employs a circular arc inside the outer conductor 7 as the support, since aluminum and copper have good ductility, open the cable outer conductor against the arcuate outer conductor 7, an outer an outer conductor 4 and the conductor 7 aft ramp inner arcuate outer cable conductor are clamped together, whether surface or a corrugated cable outer conductor of the cable and regardless of the aluminum or copper, can successfully open arc bonded to face, the different cable can not be effectively solved using the same parts and clamping the outer conductor of the problem. 参见图4和图5,本发明采用外导体1尾部斜面做台阶的方式,在外导体4与外导体7拧紧的过程中,由 Referring to FIGS. 4 and 5, the present invention employs an outer conductor tails do stepped ramp manner, the outer conductor 4 and the outer conductor 7 of screwing tight process, the

于台阶能够提供较大的压力,台阶的顶端将扎入翻开的外导体内,可使连接器在与电缆配接后达到IP68的防水等级。 To provide a greater pressure level, the top step of the tie will turn into the outer conductor, the connector may be waterproof to IP68 rating after mating with the cable. 由于不同于常规靠密封圈变形密封、所以此密封方式和电缆尺寸无关,配接任何厂家的1/2"同轴电缆同样都能达到很好的密封效果。参见图1和图6、图7,本发明采用新型的绝缘介质材料和结构使本发明具有良好的密封性能、机械性能和三阶交调。常规的连接器一般是采 Since the deformation of the sealing ring against Unlike the conventional, it is independent of the size of the cable and a sealing manner, any manufacturer mating 1/2 "coaxial cable to achieve the same effect a good seal. Referring to FIG. 1 and FIG. 6, FIG. 7 , the present invention is the use of new dielectric materials and structures of the present invention has good sealing properties, mechanical properties, and third-order intermodulation. conventional connectors typically are taken

用聚四氟乙烯作(PTFE)为绝缘支撑的,但是由于聚四氟乙烯本身的一些不足, 比如机械强度较低、不适用模压生产、耐高温性能差等。 As polytetrafluoroethylene (PTFE) as the insulating support, but some problems since polytetrafluoroethylene itself, such as low mechanical strength, is not applicable molding production, poor high temperature performance. 本发明专利则采用各方面性能均优于聚四氟乙烯的新型绝缘材料——TPX来作为内导体的主支撑零件。 This patent is used in all aspects of the new properties are superior to PTFE as an insulating material --TPX main supporting part of the inner conductor. TPX为高透明度结晶性聚合体,密度是0.82,在髙温下具有相当高的断裂伸长率和耐冲击强度和优越的耐蠕变性,熔点约为240度,在高温下的变形量小,非常适宜模具成型加工;TPX具有优异的电气绝缘性质,它的介电强度达65KV/誦,较PTFE及丙烯为优,介电常数约为2. 12,介电损失很低;TPX的吸水性很低,仅为O.Ol,因此对水及水蒸气具有极高的耐受性。 TPX is a high transparency crystalline polymer, the density is 0.82, has a relatively high elongation at break and impact strength and excellent creep resistance at temperatures Gao, a melting point of about 240 degrees, a small amount of deformation at elevated temperatures very suitable molding process; TPX having excellent electrical insulating properties, its dielectric strength of 65KV / chanting, and propylene is more preferably PTFE, a dielectric constant of about 2.12, the dielectric loss is low; TPX absorbent It is very low, only O.Ol, and therefore has a very high resistance to water and steam. 采用TPX作为内导体的主支撑零件,不但使连接器的内导体得到稳固的支撑,而且使连接器内部具有良好的密封性,最主要的是TPX稳定的电气性能使连接器获得更加优越且稳定的电气性能;同时TPX可以模压加工从而也降低连接器的生产成本。 TPX employed as the main support elements of the inner conductor, the inner conductor connection not only to obtain stable support, and that the internal connector has a good seal, the most important is TPX stable electrical performance of the connector to obtain a more excellent and stable electrical properties; TPX simultaneously embossing can thus reduce the production cost of the connector. 参见图1和图8、图9,在本发明中,另一个新颖之处就是绝缘支撑件6,绝缘支撑件6不但是给内导体2以辅助支撑,更重要的是其使得连接器8在配接电缆9 的过程中给内导体2尾部和电缆芯线配接的部位施加一定的压力,这样不但连接可靠,而且对连接器8的三阶交调指标提高有很大作用。 Referring to FIG. 1 and FIG. 8, FIG. 9, in the present invention, another novelty is the insulating support 6, not only the insulating support member 6 to the auxiliary support to the inner conductor 2, which is more important is that the connector 8 process cable 9 is connected with application of a certain pressure in the inner conductor mating portions of the tail and the cable core 2, so that only reliable connection, but also the third-order intermodulation indicator connector 8 has a significant role to improve. 图10所示为本发明配接电缆后的示意图。 FIG 10 shows a schematic view of the mating cable of the present invention.
