Abstract
The utility model discloses a coupled structure, include: casing, coupling mouth connect, the radio frequency connects, coupling stick and support medium cover. Welding or springiness contaction link to each other between coupling joint inner conductor and the coupling stick hole. The coupling connects the outer conductor and lies in the casing outside, and the coupling connects the medium and all installs in first shaft hole with coupling joint inner conductor. Coupling stick lateral wall is equipped with the step, supports the medium ways and establishes on the step for insulated isolation between coupling stick and the casing. Support medium cover and first shaft hole clearance fit, it is stable so to keep coupling stick position. And the step of coupling stick can produce very big grounded capacitance with the inside wall that forms first shaft hole, supports the medium cover and can avoid the coupling stick to link to each other and result in ground connection short circuit phenomenon with the casing. The coupling stick connects the inner conductor with the radio frequency and sets up relatively, so can form the coupling capacitance with the joint inner conductor. The utility model discloses simple structure, the size is little to convenient integrated the setting on combiner, duplexer, wave filter, electric bridge or joint.
