A radio frequency connector for establishing a radio frequency connection with a radio frequency device is described. The radio frequency connector includes a radio frequency connection interface, an interchangeable radio frequency adapter and a positioning member. The interchangeable radio frequency adapter is detachably attached with the radio frequency connection interface such that the interchangeable radio frequency adapter is configured to be detached from the radio frequency connection interface in a disassembled state of the radio frequency connector. The positioning member is configured to position the interchangeable radio frequency adapter with respect to the radio frequency connection interface in an assembled state of the radio frequency connector. The positioning member is detachably attached such that the positioning member is configured to be detached in the disassembled state of the radio frequency connector, thereby releasing the interchangeable radio frequency adapter with respect to the radio frequency connection interface. Further, a measurement system for radio frequency measurement is described.

Improved coaxial connectors and methods which have enhanced characteristics, reliability, strength, and durability. This coaxial connector system uses a flange mating system and a single slot male pin center conductor contact. The flanges use precision guiding pins and screws to axially align and secure the mating flanges together. The coaxial center conductors are electrically connected to each other by a resilient, single slotted, formed male pin and a female receptacle as center conductor assemblies. When the two flanges are fastened together, the center conductor assemblies (formed male pin and a female receptacle) mate to form an electrically conducting connection.

A coaxial connector includes a case having an inserting opening, a terminal assembly received in the case and defining a mating opening facing the inserting opening of the case, and an elastic member disposed between the case and the terminal assembly. The elastic member provides elastic forces in a radial direction of the terminal assembly to keep the terminal assembly in a first position in a free state of the terminal assembly, and the elastic member push the terminal assembly to shift to a second position different from the first position in the radial direction in a mated state of terminal assembly when the coaxial connector is mated with a complementary connector.

A base station interface device including an interface board, which is located in a housing and determines an upper portion of a first surface as a first mounting location and an upper portion of a second surface opposite to the first surface as a second mounting location, including a relay connector wherein one end is exposed to the upper portion of the first surface and the other end is exposed to the upper portion of the second surface; a base station signal matching unit mounted on the first mounting location and including a first connector coupled to the one end of the relay connector; and a base station signal processing unit mounted on the second mounting location and including a second connector coupled to the other end of the relay connector.

An electrical connector for use with coaxial cables includes a plunger urged to protrude from a case by a spring.

A high frequency signal feed through by which the ends of an input side coaxial cable and an output side coaxial cable, to be connected to each other, each comprising an interior conductor and an exterior conductor surrounding the interior conductor, are coupled to each other, showing a housing, a preferably pressure-resistant signal feed through arranged in the housing for the interior conductor, with the interior conductor being coupled at a conductive structure, arranged preferably centrally in the housing and capable of handling high frequencies, with at least one element for the galvanic separation being arranged between an input side and an output side, with the housing showing the structure for the galvanically separated coupling of the exterior conductor.

A connector and shielding ring for use with the connector includes a male portion with a shroud and a center conductor and a female portion with a jack and a socket positioned to receive the center conductor. A conductive shielding ring is positioned between the mated connector portions. The shielding ring has a body configured for surrounding flexible tines of the female portion jack and is configured to be captured between the tines and the shroud for providing a grounding path between the male and female portions of the connector. The shielding ring body has an inner surface with a diameter and an outer surface with a diameter and has a taper portion formed on a distal end of the shielding ring body for engaging a surface of the shroud. The shielding ring body has a lip extending radially inwardly at the proximal end for engaging the tines of the female portion when the male and female portions of the connector are mated.
