A pressure-applying fixture for a stripline temperature coefficient tester and its use method

Abstract

The invention relates to a pressure-applying fixture for a strip line temperature coefficient tester and a use method thereof, comprising a force-applying rod, a force-applying rod connector, a bow frame, an upper slider, a sliding hole, a lower slider, a sensor connection, and a pressure sensor , the force applying rod connector is screwed on the threaded hole of the bow frame, the head end of the bolt is placed in the sliding hole of the upper slider to rotate, and the other end is fixed on the force applying rod, and the sensor connector is threaded at one end and bottom at the other end. A cylindrical body with a curved surface runs through the through hole of the bow frame to form a sliding fit. The threaded end of the sensor connector is screwed on the lower slider, and the curved surface of the other end is placed on the pressure sensor. The technical effect is that the pressure sensor is outside the high and low temperature test box, and the contact part is very small, and the heat transfer is extremely small, so that it avoids the impact of high and low temperature. At the same time, the pressure test is more accurate. The measurement shows that the test pressure accuracy is better than ± 0.5%.

Description

technical field [0001] The invention relates to a strip line temperature coefficient tester, in particular to a pressure applying fixture for a strip line temperature coefficient tester and a use method thereof. Background technique [0002] The pressure clamps in the stripline temperature coefficient tester are generally placed in the high and low temperature box, resulting in a large volume of the high and low temperature box. At the same time, the pressure sensor is also in the high and low temperature environment, and the test accuracy cannot be guaranteed. The present invention aims to solve this problem. Problem, solve the problem of test pressure accuracy to ensure the accuracy of stripline temperature coefficient test results. Contents of the invention [0003] In view of the problems existing in the prior art, the present invention provides a pressure clamp for a stripline temperature coefficient tester and a method of use, aiming at solving the problem of pressur...
