The invention discloses a novel directional coupler. The novel directional coupler comprises a box body, wherein wiring ends are arranged at two sides of the box body, a first connection piece is fixedly arranged at a bottom end of the interior of each wiring end, a top end of the first connection piece is connected with a bottom end of a second connection piece, a top end of the second connectionpiece is fixed with one end of a triangular block, an oblique surface of the triangular block is fixed with one side of a mobile rod, a pulley is arranged at one end of the mobile rod, the pulley isarranged in a sandwiched layer of an inner wall of each wiring end, one end of the mobile rod is fixed with one end of a chain, the other end of the chain is fixed with one end of a strut, a fixed plate is arranged at one side of the strut, one end of the strut is fixed with one end of a spring, the other end of the spring is fixed with one end of the mobile rod, and a mobile plate is fixedly arranged at one side of the mobile rod. By the novel directional coupler, water can be effectively prevented from entering the wiring ends, and a component in the protection box body can be protected verywell.
Description
technical field [0001] The invention relates to the technical field of couplers, in particular to a novel directional coupler. Background technique [0002] The directional coupler is a microwave device widely used in the microwave system. Its essence is to distribute the power of the microwave signal according to a certain ratio of the directional coupler. Directional couplers are composed of transmission lines, coaxial lines, rectangular waveguides, circular waveguides, striplines and microstrip lines can all form directional couplers, so there are many types of directional couplers in terms of structure, with great differences. However, from the perspective of its coupling mechanism, it is mainly divided into four types, namely, small hole coupling, parallel coupling, branch coupling and matching double T. A directional coupler is a component that places two transmission lines close enough so that power on one line can be coupled to the other. The signal amplitudes of i...
