Spring loading connector

Abstract

The present invention provides a spring loading connector which comprises a socket and an adapter connected with the socket, wherein the socket comprises a housing and a central conductor positioned in the housing. The adapter is provided with a plug which is composed of the central conductor, an insulator and an adaptor housing that are assembled from the inner part to the outside. The inner surface of the housing of the socket comprises a first conical surface, a second conical surface and a cylindrical surface positioned between the two conical surfaces. The adapter comprises an elastic component, and the central conductor in the adapter is provided with a groove for receiving the central conductor of the socket. The insertion end of the housing of the adapter is a curved surface whichcontacts and matches with the second conical surface in the inner surface of the housing of the socket. The structure of the spring loading connector can allow large axial and radial deflection. Furthermore the spring loading connector has excellent electromagnetic shielding and can bear higher transmission power, and simultaneously has better radio frequency electrical performance.

Description

technical field [0001] The invention relates to a radio frequency coaxial connector. Background technique [0002] Today, base station designs are increasingly miniaturized, and the transmitter module and receiver module are usually integrated on the same PCB (printed circuit board). Therefore, while the transmission power increases, there are higher requirements for the axial and radial offset and radio frequency shielding performance of the radio frequency coaxial connector. [0003] In the board-to-board connection design, due to manufacturing and assembly errors, the part that needs to be inserted into the RF coaxial connector between the boards will have a certain horizontal position tolerance and vertical position tolerance, which is reflected in the RF coaxial connection. The problem on the connector is the radial and axial tolerances-allowing the radial and axial tolerances of the RF coaxial connector when connecting board to board. However, the existing radio freq...

Problems solved by technology

However, since the design of this type of connector still adopts the structure of slotted outer conductor and inner conductor, there is still a certain limit to the radial offset. In actual use, the allowable radial offset of MMBX is + / -0.4 mm, the axial offset is + / -0.3mm, the allowable radial offset of SMP is + / -0.25mm, and the axial offset is 0-+0.25mm

In addition, since both of them adopt a slotted outer conductor structure, large radio frequency leakage will be generated, which will generate certain electromagnetic interference, which is not conducive to modular and miniaturized design.
