The invention relates to a connection method and a connection arrangement. The solution employs an adapter fastener, which is intended for both an adapter connection and a circuit board connection, the adapter fastener being electrically conductive. The adapter fastener comprises a hole, which extends through the adapter fastener and to which a coaxial cable is fixed. The sheath of the coaxial cable is electrically connected to the adapter fastener and a male connection is formed at the adapter fastener by means of an inner conductor of the coaxial cable. In the adapter connection, the inner conductor of the coaxial cable is connected electrically to a female contact of a standardized adapter and the adapter fastener is connected electrically to the frame of the standardized adapter by means of adapter protrusions. In the circuit board connection, the adapter fastener is fastened by means of circuit board protrusions to a circuit board and the adapter fastener is connected electrically by means of the circuit board protrusions to the earth of the circuit board. In addition, the inner conductor of the coaxial cable, used in the male connection, is connected electrically to an electrical conductor of the circuit board.
A new and improved radio frequency coaxial connector mounting flange structure, to be mounted upon a radio frequency system subassembly, comprises a modular component which has recessed end portions for enabling adjacent coaxial connector mounting flange structures to effectively overlap each other, when a plurality of the coaxial connector mounting flange structures are disposed within a longitudinal, horizontally oriented array, such that not only can the longitudinal extent of the longitudinal array of the plurality of coaxial connector mounting flange structures be minimized, but in addition, the overall longitudinal extent of the radio frequency system subassembly can be reduced. Still further, the overlapped end portions of the adjacent coaxial connector mounting flange structures can effectively be secured onto the radio frequency system subassembly by a common fastener thereby effectively reducing the number of fasteners and the corresponding time to install such fasteners.
A microwave device includes a circuit board having a microstrip layer, a ground plane, and a dielectric layer therebetween. The circuit board has a shield receiving slot for longitudinally receiving the end of a shield conductor of a coaxial cable. The coaxial cable also has an inner conductor having an end that extends longitudinally outwardly from the end of the shield conductor. The microstrip layer has an inner conductor contact adjacent the shield receiving slot that connects to the end of the inner conductor. The device may include a conductive layer in the shield receiving slot to connect to the ground plane. The shield receiving slot may have a T shape and extend through the circuit board. The device may include a mounting fixture connecting an end of the shield conductor to the circuit board.
An adapter having a housing, a ground clip and an adapter subassembly all located in the housing. The adapter subassembly includes a proximal portion that can be coupled to a coaxial connector and a distal portion that can be coupled to a printed circuit board. A central conductor in the form of an elongated shaft that runs through the subassembly and has a ball contact end for contacting a conductor located on a printed circuit board and the elongated shaft is tapered in a region near the bal contact.
