Abstract
The utility model relates to an elastic contacting RF coaxial connector which is composed of an internal conductor, an insulator, a pressing sleeve, an external conductor, an elastic contact piece, a sealing ring, a lead sleeve and a threaded sleeve, wherein the elastic contact piece is arranged at one end of the internal conductor; the insulator is arranged at the connecting position of the middle of the internal conductor and the external conductor; the pressing sleeve is arranged at the right of the insulator; the external conductor is arranged at the external layer of the internal conductor; the sealing ring is arranged between the external conductor and the threaded sleeve; and the lead sleeve is arranged in the threaded sleeve. Thus, the mechanism of early failure caused by the contact problem of a RF coaxial connector can be effectively solved. The utility model has the advantages of simple structure and convenient use.
Description
Technical field:
The utility model relates to the mobile communication base station main feeder cable with 7/8 type radio frequency (RF) coaxial connector, particularly relates to a kind of Elastic Contact formula radio frequency (RF) coaxial connector.
Background technology:
The mobile communication base station main feeder cable produces at present and mainly uses 7/8 " the bellows radio frequency coaxial-cable; being connected between main feeder cable and wire jumper antenna is to adopt 7/8 radio frequency (RF) coaxial connector, and the connected mode of this connector inner wire and cable inner conductor is: the connector inner wire is filled in the internal diameter of cable inner conductor.Because GB or rower have standard code to the external diameter of cable inner conductor, internal diameter is not made detail requirement, the internal diameter size of each production firm's main feeder cable inner wire is different, have to φ 8.5mm from φ 7.9mm, to cause the continuous change of the inner conductor outer diameter of connector, various cables can not be unified during on-the-spot the installation, directly have influence on the electrical performance indexes of mobile base station, increasing voltage standing wave ratio at least makes base station transmitting power reduce to have influence on the covering radius of base station, greatly then directly make signal interruption, bring loss for mobile operator and client.
Summary of the invention:
In order to solve 7/8 " demand of the multiple internal diameter size of bellows inner conductor of radio frequency coaxial cable, the utility model provides a kind of radio frequency (RF) coaxial connector of new structure.This radio frequency (RF) coaxial connector can satisfy the size matching requirements between cable diameter of bore φ 7.9MM to φ 8.5MM, also satisfies the requirement of IEC169 standard and " tracking exchage 50 Ω radio frequency (RF) coaxial connectors " standard fully.The purpose of this utility model is to realize like this, a kind of Elastic Contact formula radio frequency (RF) coaxial connector, formed by inner wire, insulator, gland, outer conductor, elastic contact chip, sealing ring, wire sleeve, swivel nut, it is characterized in that: an end of inner wire is provided with elastic contact chip, middle part and outer conductor junction at inner wire are provided with insulator, and the right of described insulator is provided with gland; Outer conductor is arranged on the skin of inner wire, is provided with sealing ring between outer conductor and the swivel nut, is provided with wire sleeve in described swivel nut.
The utility model technology efficiently solves the main feeder cable requirement that operator adapts to each manufacturer at the construction field (site), satisfy the requirement of the electrical performance indexes of base station construction process main feeder cable connector, solved because the mechanism of the early failure that the radio frequency (RF) coaxial connector contact problems cause.
