A coaxial connector to be connected to a mating connector includes a fixed assembly body and a movable assembly body connected to the fixed assembly body along an axial direction. The fixed assembly body includes a fixed side inner conductive body; a holding member for holding the movable assembly body; a fixed side insulation member for insulating between the fixed side inner conductive body and the holding member; and a first urging member for using the movable assembly body. The movable assembly body includes a movable side inner conductive body; a movable side outer conductive body; and a movable side insulation member. The movable side inner conductive body includes a first relay terminal having a retaining portion, a second relay terminal having a contact portion retained in the retaining portion, and a second urging member for urging the second relay terminal toward the fixed side inner conductive body.

Coaxial connector

A traveling-wave tube is provided which has a heat radiating structure with good heat conductivity from the collector core to the heat sink. An insulator is disposed around and in contact with the outer peripheral surface of a collector electrode and has a slit in parallel with a tube axis. A radiator is disposed outside of and in contact with the insulator and has a slot formed on the top surface thereof extending in parallel with the tube axis. The radiator also has one or more grooves that insect the slot and receive therein a fastening member having a length shorter than the length of the groove and formed with screwed holes extending through both end portions thereof in the axial direction. By adjusting amounts by which bolts are screwed into the fastening member through the throughholes formed through the radiator, the gaps in the groove between the radiator and both end surfaces of the fastening member can be varied. This allows a fastening force to be transmitted from the radiator to the entire insulator, thereby readily adjusting the degree of contact between the radiator and insulator and collector electrode.

Traveling-wave tube having heat radiating structure with high thermal conductivity

Collector structure having a loss ceramic member

A flexible detecting terminal (6) is provided within an inside connector (1) in the vicinity of the cylindrical outer conductor (5) which surrounds a central conductor (4). An outside connector (52) has a central conductor (52A) for connection with the central conductor (4) and a conductive shell (52B) fitted over the cylindrical outer conductor (5). A contact section (6B) is provided on the detecting terminal (6) such that when the connectors (1) and (52) are not connected to each other, it is spaced from the cylindrical outer conductor (5) but when the connectors (1) and (52) are connected to each other, it is brought into resilient contact with the cylindrical outer conductor (5).

Coaxial connector for switching antennas

A pair of male and female coaxial connectors which includes male and female rectangular housings with a plurality of through holes arranged at a predetermined interval in a lengthwise direction of the rectangular housing in which male and female terminals are arranged in at least one line. The male terminals includes a plurality of male outer conductors each fitted in one of the through holes and having upper and lower inner surfaces extending parallel to a specified plane which extends in the lengthwise direction and in a widthwise direction of the rectangular housing; a plurality of male dielectric blocks each fitted in a rear portion of one of the male outer conductors to define a cavity within the one male outer conductor; and a plurality of male central conductors each projecting into the cavity from one of the dielectric blocks and having upper and lower outer surfaces extending parallel to the specified plane.
