Abstract

The invention discloses a test seat of a passive microwave radio frequency transformer. The test seat comprises a cavity, a circuit board, a positioning board and a spring thimble clamp. An open-ended cavity of an upper end surface of the cavity is fixedly connected to a pedestal. The circuit board and the positioning board are fixedly placed in the cavity from bottom to top. The circuit board is connected to monitoring equipment through a lead. The positioning board is provided with a groove which is used for placing the transformer. The spring thimble clamp is fixedly connected to a stand column and is provided with a compression bar which can elastically recover stretching. A position of the compression bar directly faces the groove. The stand column is fixedly connected to the pedestal. In the invention, a tested device is placed in the groove so as to carry out positioning; and the compression bar which can elastically recover stretching is used to carry out fastening so that tight contact of a pin is realized. By using the test seat of the invention, problems of mechanical damages and poor contact brought by a welding mode in the prior art are solved. The test seat possesses characteristics that the structure is simple; reliability and maneuverability are high; loading and unloading are convenient; test efficiency is high; the device has no loss and so on. And the test seat is suitable for a test of a large quantity of products.
