Description
Technical field:
The utility model relates to the injection moulding solder type radio frequency cable device that is connected between mobile communication base station main feeder cable and antenna.
Background technology:
In mobile communication system, the communication base station cable unit is mainly used in the connection between connection, main feeder cable and the base station equipment of antenna end and main feeder cable.Radio frequency cable generally can be divided three classes: flexible cable, ripple copper pipe cable and half be semi-flexible cable just.The assembly quality of cable assembly directly has influence on the water resistance of the electrical performance indexes and the cable of assembly.Cable assembly attaching mode generally has three kinds of modes: compression joint type, clipping and welded type, can select different attaching modes according to the cable that the user uses for use with joint, and hermetically-sealed construction adopts corresponding different mode to carry out waterproofing design.The cable of mobile communication base station use at present is ripple copper pipe cable, and connector and its connected mode are clipping, and mounting means is mainly manual installation, and its reliability relies on the technical merit and the quality of installation personnel, the stability that is difficult to ensure the quality of products; This kind attaching mode is a thread connecting mode, and the vibrationproof performance is not good yet, especially is installed on the iron tower, and through exposing to the weather, screw thread is loosening easily, the also difficult electric property that reaches the best.
Because the cable assembly that communication base station uses is mainly used in cat head, outdoor work environment is poor, and water resistance requires than higher.The instability of voltage standing wave ratio and third order intermodulation often appears producing owing to the influence of typhoon heavy rain in the base station cable assembly, influences user's the proper communication and the overlay area of base station.
Summary of the invention:
The utility model provides a kind of and has good electrical performance and water resistance in order to solve the deficiency that prior art exists, and injection moulding solder type radio frequency cable device simple in structure, that reliability is high, easy for installation.The technical scheme that the utility model solves is, injection moulding solder type radio frequency cable device is made up of O type circle, nut outer conductor, injection moulding sheath, cable, it is characterized in that: in outer conductor, be provided with two insulators, be respectively insulator 1 and insulator 2, middle part at insulator 1 and insulator 2 is provided with inner wire, and an end of described inner wire links to each other with the inner core of cable; Upper end at outer conductor is provided with nut, and described outer conductor lower end links to each other with the outer core of cable, is provided with O type circle between nut and outer conductor; Be provided with the injection moulding sheath at cable and outer conductor junction.The utility model utilizes advanced solder technology, and the internal and external conductor welding with cable internal and external conductor and connector makes cable assembly have the good characteristics of reliable operation, electric property and mechanical performance.In order to reach the IP68 waterproof requirement, blank area and cut cable that welding is good adopt hot injection moulding process to seal, and injection moulding can not only be played sealing function, and the cable of splitting stripping plays the certain protection effect.Thereby this cable assembly can satisfy requirements of one's work under rugged environment, can satisfy open-air long-term use the in mobile communication base station fully.In addition,, the linkage editor of assembly is become be more prone to, shortened installation time, reduced production cost simultaneously because this structural design is simple.

Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing
In accompanying drawing 1, advanced high-frequency current heating solder technology is adopted in the welding of the internal and external conductor of cable internal and external conductor and connector.In the welding process, heating is heated evenly fully from inside to outside, and speed is fast, can not damage the internal structure of cable and the outward appearance of connector, therefore adopts this kind advanced person's solder technology, has both improved assembling speed, has reduced cost, has also improved electrical property.In connector outer conductor and cable outer conductor welding position and the cable cover(ing) part injection moulding of being peelled off; injection moulding is under uniform temperature and certain pressure effect and uses the injection mould of regulation to carry out injection moulding; after the injection moulding; moulding is connected closely with cable, connector; integrator; therefore both improved water resistance, the cable of splitting stripping again plays the certain protection effect, and outward appearance plays beautification function.Detection the utility model through the Tai Er of Ministry of Information industry demonstration center reaches on electrical performance indexes, mechanical performance index and water resistance and surpasses industry standard, can satisfy the long-term outdoor use of domestic and international mobile communication base station fully.
