Problems solved by technology

The coaxial microstrip connector part of the connection device provided by the present invention no longer uses the method of pouring epoxy resin glue to fix the positions of the inner conductor and the outer conductor, but uses a mechanical limit step to complete the entire coaxial microstrip connector. The position of the connector is fixed, which effectively solves the problems of poor electrical performance indicators and potential electromagnetic leakage caused by the existing coaxial microstrip connector opening holes on the outer conductor and insulating support and pouring epoxy resin glue; and The present invention also adopts the method of coplanar compensation, that is, an insulating gasket is designed at the joint between the coaxial microstrip connector and the tester, so that the test results are more accurate

Abstract

The invention discloses a radio frequency coaxial micro-strip connecting device. The radio frequency coaxial micro-strip connecting device comprises a coaxial micro-strip connector. The coaxial micro-strip connector comprises outer conductors, a first inner conductor and insulating supports arranged between the outer conductor and the first inner conductor. A first insulating support and a first outer conductor, the first insulating support and the first inner conductor, a second insulating support and the first inner conductor as well as the second insulating support and the second outer conductor are respectively fixed and assembled to each other through matched limit steps in the axial direction of the coaxial micro-strip connector. According to the radio frequency coaxial micro-strip connecting device, the coaxial micro-strip connector is fixed by using the mechanical limit steps rather than by being filled with epoxy resin glue for fixing the inner conductor and the outer conductors, so that the problems of electromagnetic leakage hidden danger and the like of an existing coaxial micro-strip connector are effectively solved.

Description

technical field [0001] The invention relates to a radio frequency coaxial microstrip connection device. Background technique [0002] The radio frequency coaxial microstrip connection device involved in the present invention is an important component for the connection between the coaxial line and the microstrip line. As a very popular planar transmission line, microstrip line is widely used in various microwave devices because it can be processed by photoprinting process and easily integrated with other passive and active microwave devices. To connect the microstrip circuit with the external coaxial transmission system, a coaxial microstrip connector must be used for transition. The coaxial microstrip connector is a commonly used coaxial microstrip transition device. [0003] At present, coaxial microstrip connectors commonly used in China such as figure 1 As shown, most coaxial microstrip connectors of this type adopt the method of opening the outer conductor 1' and the ...
