Compact RF Coaxial Connectors

Abstract

The present invention provides a compact radio frequency coaxial connector, which includes a main connecting part and a central pin that cooperate with each other; the main connecting part includes an insulating support, a first inner conductor is fixed in the middle of the insulating support, and one end of the first inner conductor is connected to The second inner conductor is connected, the end of the second inner conductor far away from the first inner conductor is fixed with an insulator, the insulator is provided with a guide hole, the end of the second inner conductor with the insulator can rotate relative to the first inner conductor; the center pin can be fixed Connected to the connecting plate, the central pin can pass through the guide hole and be connected to the second inner conductor, and the diameter of the guide hole gradually increases along the direction away from the second inner conductor. This compact RF coaxial connector abandons the traditional three-body board-to-board connection method, and uses the movable connection of the center pin to provide radial and axial tolerances, which reduces the number of products, reduces product costs, and achieves compactness type 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 ...
