Small-volume low-intermodulation RF connector

Abstract

The present invention provides a small-volume low-intermodulation RF connector. A male outer conductor is connected on a female outer conductor through a screw sleeve, the front end face of the male outer conductor is in conductive contact with a step on the inner hole of the female outer conductor to form a first conductive contact surface; a fixing section at the rear section of an elastic contact piece is inlaid in the male outer conductor, the elastic portion of the front section is extended to the outer portion of the male outer conductor to be in contact with the inner side circular conical surface of the female outer conductor to form a second conductive contact surface; radial and axial conductive contact surfaces achieve the intermodulation structure, the volume is small, the weight is light, the installation is fast, the connection operation is convenient, the coaxiality is good, the contact pressure of the inner and outer conductor interfaces are high, the reflection factorand the insertion loss are small, the crosstalk distortion is low, the anti-impact vibration performance is good, the outer conductor contact interface is reliable in seal, high in power and high in frequency band, and can be suitable for low-intermodulation requirements of 5G communication; and moreover, the raw material consumption of the copper conductor is reduced, the cost is reduced, and theintegration effect is good.

[0002] RF connectors are important connecting and disconnecting components in microwave transmission systems. The connected RF circuits mainly include between functional modules inside wireless communication equipment, between antennas and transmitting and receiving modules, and between various RF coaxial cables. , microstrip circuit and printed circuit connections, etc.; in the field of telecommunications, with the development of base station radio frequency units and antennas in the direction of miniaturization, the supporting RF connectors also need to be correspondingly small in size and high in size. Power, low intermodulation, and high frequency band development, especially the frequency band used by 5G communication has been increased to 6GHz. Traditional connectors cannot meet the requirements of small size, high integration, moderate power, high frequency band and low intermodulation at the same time. Although some products The use frequency band can meet the use requirements, but the intermodulation and power indicators cannot meet the use requirements. Some product intermodulation indicators can meet the use requirements but the use frequency is relatively low; for example, 4310, 7 / 16, and N-type connectors in the prior art can It meets some requirements, but has the defects of large volume and poor integration. The smallest size N-type connector has a mating thread of 16mm; small size connectors such as SMA, SMB, etc. have problems of too small power and poor stability of intermodulation indicators. ; Therefore, traditional connectors cannot meet the requirements of 5G communication
