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 system selected connector.

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1/2"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 1/2 "coaxial cable, but due to the difference of size and structural constraints cable connector, substantially different manufacturers to produce cables need to have a 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型插孔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成产成本增大,更不适合野外的安装和更换。 Mating conventional 1/2 "L29 socket 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 the cost of production of the connector is increased, 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型插孔接触件射频同轴连接器存在明显的不足。 In summary, the present mating 1/2 "L29 socket contact type coaxial RF coaxial connector obvious deficiencies.

五、具体实施方式: V. DETAILED DESCRIPTION:

参见图1,本发明包括相互连接的第一外导体2和第二外导体6,第一外导体1和第二外导体6之间为插孔2,在插孔2内靠近第一外导体1 一侧设置有作为插孔2主支撑的绝缘支撑件3,插孔2尾部靠近第二外导体6处设置有作为插孔2辅助支撑的绝缘支撑件5,作为插孔2主支撑的绝缘支撑件3为TPX绝缘支撑件,第二外导体6内部设置有一段圆弧,第一外导体1尾部设置有带有台阶的斜面。 Referring to Figure 1, 2 between the insertion hole 6 in the insertion hole adjacent to the first outer conductor 2 of the present invention comprises a first outer conductor 2 connected to each other and the second outer conductor 6, a first outer conductor 1 and the second outer conductor 1 side is provided with a main support of the jack 2 insulating support 3, near the end of the second connector 2 6 is provided with an outer conductor of the jack 2 as the insulating support auxiliary support 5, the jack 2 as the main support of insulating the support member 3 is TPX insulating support member, the outer conductor 6 is provided with a second inner segment of a circle, a first outer conductor 1 is provided with a tail of a stepped ramp.

参见图2和图3,本发明采用第二外导体6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第二外导体6的圆弧上, 由于第一外导体1尾部斜面和第二外导体6内部圆弧共同夹紧电缆外导体,无论是光面还是波纹电缆,也无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 second outer conductor 6 inside a circular arc as a support, since aluminum and copper have good ductility, a round cable outer conductor against the second outer conductor 6 of the open on the arc, since the first outer conductor 1 and the second outer conductor tail inclined surface 6 inside 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, have bonded to smoothly open arcuate surface, effectively solve the problem of different cables can not use the same parts and clamping the outer conductor. 参见图4和图5,本发明采用第一外导体1尾部斜面做台阶的方式,在第一外导体1与第二外导体6拧紧的过程中,由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。 Referring to FIGS. 4 and 5, the present invention employs a first outer conductor 1 made aft ramp step manner, in the process of the first outer conductor 1 and the second outer conductor 6 tightening, since the step to provide a greater pressure, the step of the top tie into the open 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得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用聚四氟乙烯(PTFE)作为绝缘支撑的,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。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。TPX 为高透明度结晶性聚合体,密度是0.82,在高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/mm, 较PTFE及丙烯为优,介电常数 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 materials and structures so that the insulating medium of the present invention has good sealing properties, mechanical properties, and third-order intermodulation. conventional connectors typically is polytetrafluoroethylene (PTFE) as the insulating support, but since the poly tetrafluoroethylene itself some shortcomings, such as low mechanical strength, is not applicable molding production, poor high temperature performance. Patent present invention is the use of new materials --TPX insulating properties are superior in all aspects to PTFE as an internal the main support part is transparent conductor .TPX crystalline polymer, the density is 0.82, has a relatively high elongation at break and impact strength and excellent creep resistance at high temperatures, melting at about 240 degrees, at an elevated temperature a small amount of deformation under very suitable molding process; TPX having excellent electrical insulating properties, its dielectric strength of 65KV / mm, more preferably propylene and PTFE, the dielectric constant 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。采用TPX作为插孔的主支撑零件,不但使连接器7插孔2得到稳固的支撑,而且使连接器7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7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。参见图l和图8、图9,在本发明中,另一个新颖之处就是绝缘支撑件5,绝缘支撑件5不但是给插孔2以辅助支撑,更重要的是其使得连接器7在配接电缆8的过程中给插孔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,而且对连接器的三阶交调指标提高有很大作用。图IO所示为本发明配接电缆后的示意图。 It was 2.12, the dielectric loss is low; TPX water absorption is very low, only O.Ol, and therefore has a very high resistance to water and steam using the jack as TPX main support part, not only the connector. 7 jack 2 to give a solid support, and the inside of the connector 7 has a good seal, the most important is TPX stable electrical performance of the connector 7 obtains superior and stable electrical properties; TPX can simultaneously thereby also embossing reduce the production cost of the connector. Referring to FIGS. l and 8, FIG. 9, in the present invention, another novelty of the insulating support 5 is, not only the insulating support 5 to the socket 2 to an auxiliary support, more importantly, 7 so that the connector which is applied some pressure to the tail and the jack 2 contact with the cable core during the mating portions of the cable 8, so that only reliable connection, but third order intermodulation indicators there are improved connector major role. FIG IO schematic view of the present invention is shown with cables.
