Flexible solderless surface mount RF modules, RF contacts and integrated sockets

Abstract

The invention relates to an elastic solderless surface mount radio frequency module, a radio frequency contact and a socket. The elastic solderless surface mount radio frequency module includes a surface mount radio frequency contact and a radio frequency fixing module, wherein the radio frequency fixing module is fixed to the backboard and can Relative to the axial elastic floating of the backboard, the surface-mounted radio frequency contact is assembled in the installation hole of the radio frequency fixed module and has an inner conductor elastically connected to the backplane through a floating end capable of axially floating at the front end. The present invention realizes the elastic contact between the inner conductor of the contact piece and the pad of the backplane through the inner conductor of the radio frequency contact piece with the axial floating function, and when the inner conductor retracts, the spring is compressed to provide an appropriate positive pressure to ensure reliable elastic contact; The elastic floating connection between the RF fixed module and the backplane realizes the elastic connection between the outer shell of the contact piece and the backplane. At the same time, the RF fixed module can also realize the floating fixation with the backplane through studs, which not only ensures that each radio frequency hole is welded to the backplane. To ensure the alignment accuracy of the disc, it is necessary to provide sufficient locking force.

Description

technical field [0001] The invention belongs to the technical field of connectors, and in particular relates to an elastic solderless surface mount radio frequency module, a radio frequency contact piece and an integrated socket. Background technique [0002] The vertical surface-mount RF contacts used for the backplane mainly adopt the structural form of soldering and solder-free hard connection at present.

The surface-mounted RF contact in the form of welding adopts SMT mounting technology, based on the reflow assembly process, to realize the assembly of the surface-mounted RF contact and the backplane. The structure of the surface-mounted RF contact can refer to CN 10106785740. This type of surface-mounted RF contact Components and placement technology are more common, its radio frequency performance is stable and has certain environmental adaptability, but the assembly process is more complicated, and the maintainability of backplane components is poor; another type is surface-mounted radio frequency connectors that do not require soldering and hard connection , this type of connector is fixed to the backplane through the flange structure of the outer shell, the inner conductor slightly protrudes from the end face of the tail, and the flange structure is used to force the inner conductor and the pad to contact

The product mainly solves product testing and module interconnection, but if the backplane is thin, when there are many or dense connectors, the surface of the backplane is prone to flatness deterioration, resulting in poor contact between the inner and outer conductors of the connector; on the other hand, Under different environmental stresses, excessive force on the inner conductor may lead to shrinkage of the needle and cause signal interruption
