Compact type RF coaxial connector

Abstract

The invention provides a compact type RF coaxial connector, which comprises a main connecting part and a center pin which are matched with each other, wherein the main connecting part comprises an insulating support, a first inner conductor is fixed in the middle part of the insulating support, one end of the first inner conductor is connected with a second inner conductor, an insulator is fixed to one end, away from the first inner conductor, of the second inner conductor, a guide hole is formed in the insulator, and the end (provided with the insulator) of the second inner conductor can rotate relative to the first inner conductor; and the center pin can be fixedly connected on a connecting plate, the center pin can pass through the guide hole to be connected with the second inner conductor, and the diameter of the second inner conductor is gradually increased along a direction away from the second inner conductor. The compact type RF coaxial connector abandons the traditional three-body type board-to-board connecting method, adopts movable connection of the center pin to provide radial and axial tolerances, reduces the number of products, reduces product cost, and achieves a compact design.

Description

technical field [0001] The invention relates to a compact radio frequency coaxial connector. Background technique [0002] Today's base station designs are increasingly miniaturized. Among communication equipment manufacturers, RRU designs also tend to be more compact, easier to install, and lower in cost. Therefore, for inter-board connectors, it is necessary to achieve a more compact connection to achieve the purpose of transmitting power and signals, and at the same time must provide a large axial and radial offset, as well as a blind mating function. [0003] In the board-to-filter connection design, due to manufacturing and assembly errors, there will be a certain horizontal position tolerance and vertical position tolerance for the part that needs to be inserted into the RF coaxial connector between the board-to-filters, which is reflected in the RF coaxial connector. The problem on the shaft connector is the radial and axial tolerances, that is, the radial and axial ...
