Aluminum alloy smooth rod cable radio frequency coaxial connector

Abstract

The invention provides an aluminum alloy smooth rod cable radio frequency coaxial connector which comprises an inner conductor, an injection insulator and a pressing sleeve. The inner conductor is arranged in a center of an inner cavity of an outer conductor. An outer ring small head of the inner conductor is provided with the injection insulator, and a right end large head is provided with the pressing sleeve. A right end surface of the outer conductor is provided with a rear screw sleeve, and is provided with a sealing ring at a surface connection part. An inner ring of the rear screw sleeve is provided with a left turning pipe thread with coning and is provided with a sealing ring in a right end groove. The aluminum alloy smooth rod cable radio frequency coaxial connector can satisfy an assembly requirement of a 7 / 8'' aluminum cable, and completely can satisfy a '50 ohm radio frequency coaxial connection for mobile communication' standard technical requirement through testing and actual use. A problem of early failure caused by that an original coaxial connector can not be matched with the aluminum cable is solved. According to the invention, the left turning pipe thread with coning is used in the rear screw sleeve and a cable sheath for connection, sealing and waterproof problems are solved, and functions of connection and positioning in cable installation can be played.

Description

Technical field: [0001] The invention relates to a 7 / 8" type aluminum alloy smooth bar cable radio frequency coaxial connector for a main feeder cable of a mobile communication base station. Background technique: [0002] The mobile communication base station transmits the main feeder cable. At present, the 7 / 8″ copper bellows RF coaxial cable is mainly used, and the connection between the main feeder cable and the jumper antenna is a 7 / 8″ RF coaxial connector. The cost of cables continues to increase. At present, cable factories have introduced coaxial cables with smooth aluminum tubes instead of corrugated tubes. This kind of cable not only has low loss, but also has a lighter weight. The cost is 1 / 3 lower than that of the original copper cable, and its electrical performance index is better than that of corrugated tubes. Cables bring greater benefits to mobile operators and customers. Since the structure of the smooth aluminum tube RF coaxial cable is different from that...

AI Technical Summary

Problems solved by technology

It solves the problem of early failure caused by the incompatibility between the original coaxial connector and the aluminum cable, and meets the requirements of the electrical performance index of the main feeder cable connector in the base station construction process

At the same time, the problem of sealing and waterproofing between the aluminum alloy cable and the connector is solved. The original bellows cable can add a sealing ring in the bellows due to the large bellows structure, but the outer conductor structure of the current aluminum alloy smooth rod cable cannot use a sealing ring, so In the present invention, the rear screw sleeve and the cable sheath are connected by a left-handed pipe thread with a taper, which can not only solve the problem of sealing and waterproof, but also play a role in positioning when connecting and installing the cable.
