Testing clamp general for drop-in isolator

Abstract

The invention discloses a testing clamp general for a drop-in isolator. The testing clamp comprises two workbenches (3), a left-right moving sliding table (4), a testing supporting block (5), a vertical moving sliding table (6), a base plate (7) and a support (8); the workbenches (3) are fixedly connected with the left-right moving sliding table (4); one end of each workbench (3) is provided witha micro-strip transmission line (1) and a coaxial connector (2); the testing supporting block (5) is located between the two workbenches, the testing supporting block (5) is fixed to the portion abovethe vertical moving sliding table (6), and the vertical moving sliding table (6) is located on the base plate (7). The testing clamp general for the drop-in isolator solves the complex testing problem, the testing problem of drop-in isolators of various sizes is solved through the mobile changing testing clamp, the production efficiency of the product can be greatly improved, and the production cost of the product is lowered.

Description

technical field [0001] The invention relates to the field of measurement of microwave components, in particular to a universal test fixture for strip line isolators. Background technique [0002] The stripline isolator is an important basic device in microwave engineering. It is widely used in various civil and military equipment such as civil communication, microwave measurement, radar, communication, electronic countermeasures, and aerospace. It is mainly used to achieve inter-stage isolation, protect the front-end system, and prevent signal crosstalk. [0003] Stripline isolators have different dimensions and interface dimensions depending on their frequency, carrying power, and user environment. A typical stripline isolator structure is as follows: figure 1 with 2 As shown in the figure, A is the line port at the input end, B is the line port at the output end, C is the cavity of the isolator with line, and D is the bottom surface of the isolator with line; [0004] D...

AI Technical Summary

Problems solved by technology

[0009] In order to solve the problem that the traditional test fixture of strip line isolator cannot meet the general testing requirements of various devices, the present invention adds a left and right precision moving slide table and an up and down moving slide table on the basis of the traditional test fixture, which can freely and precisely test the gaps between the test ports. The distance and the distance from the test port to the bottom are adjusted, which effectively meets the test of various sizes of isolators with wires
