Waterproof self-locking radio-frequency coaxial connector assembly

Abstract

The invention discloses a waterproof self-locking radio-frequency coaxial connector assembly. The assembly comprises male and female radio-frequency coaxial connectors; the male connector comprises a cylindrical clamping jaw, a bush and a thread sleeve; a conical hole and a clamping jaw annular bulge are arranged at the front end of a cylindrical body of the clamping jaw; the clamping jaw annular bulge is provided with an outwards tilted radial conical surface which is tilted outwards and radially; an outer threaded section is arranged on the outer wall surface of the bush; the thread sleeve is provided with an inner threaded section and a first thread sleeve annular bulge which is bulged inwards; the thread sleeve is in threaded connection with the outer threaded section of the bush through the inner threaded section; the first thread sleeve annular bulge props against the outer conical surface when the thread sleeve is moved forwards through manual screwing; the outwards tilted radial conical surface of the clamping jaw props against a female annular bulge; the assembly further comprises a cylindrical waterproof sleeve made of an elastic waterproof material; and two ends of the waterproof sleeve tightly sleeve a female outer conductor and a cable respectively. According to the assembly, the female and male connectors are not mutually rotated and moved after being inserted and combined, so that stable dynamic intermodulation and stable radio-frequency signal transmission are achieved and the waterproof effect is good.

Description

technical field [0001] The invention relates to a communication signal transmission device, in particular to a radio frequency coaxial connector assembly for transmitting radio frequency signals, belonging to the technical field of communication transmission. Background technique [0002] The RF coaxial connector assembly is an interface component that transmits RF signals. It is used to form electrical connections and transmit RF signals between devices and between systems and subsystems, thus constituting the basic components necessary for a complete system. , it plays the role of connecting or disconnecting coaxial cables, microstrip circuits, and transmitting radio frequency signals in microwave circuits. The product quality and reliability of RF coaxial connector assemblies directly affect the quality and reliability of RF signals. [0003] The existing radio frequency coaxial connector assembly, such as the Chinese invention patent application, a structure disclosed b...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned radio frequency coaxial connector assembly has the following three defects during use: (1) Since the female connector and the male connector are clamped by a snap ring structure, after the plug-in combination, the female connector and the male connector The head connectors will rotate and move each other, resulting in qualified static intermodulation, but large fluctuations in dynamic intermodulation; The connection of the male and female connectors is unreliable, and even the inner and outer conductors of the female and male connectors are separated, which seriously affects the transmission performance of radio frequency signals; (3) The combination of female and male connectors Finally, in order to be waterproof and moisture-proof, especially when outdoors, usually the electrical tape is wrapped on the assembly first, and then the waterproof glue is wrapped on the electrical tape, and the electrical tape is wrapped after the waterproof glue is wrapped. The construction is slow, inefficient, and requires a lot installation space to operate
