Problems solved by technology

[0002] In high-frequency circuits, microwave circuit boards are usually small in size and indeterminate in shape so that it is difficult to perform fixed tests on them; when testing microwave circuits with instruments, butt cables may cause SMA connectors to fall off, and due to soldering. The error is also more obvious

Abstract

The invention discloses an adjustable microwave circuit test fixture. The fixture of the invention is a fixture which can fix microwave circuit boards of different shapes and sizes; the fixture can be divided into a bottom sheet layer, a gasket sheet layer and a pressing sheet layer which are distributed sequentially from bottom to top; the gasket sheet layer includes two metal sliders and an SMA connector; slide slot structures are formed in a bottom plate and pressing sheets; and fixing holes are formed in the metal sliders and are used for fixing the SMA connector. According to the adjustable microwave circuit test fixture of the invention, the positions of the metal sliders and the pressing sheets are adjusted through the slide slots and are fixed through screws, and therefore, the microwave circuit boards of different shapes can be well fixed, and the microwave circuit boards can be made to be in multi-point grounding states; since the SMA connector is fixed on the metal sliders through screws, and therefore, problems caused by poor welding or poor grounding in a circuit test can be solved, and the problem of the falling of the SMA connector caused by cable connection can be also solved.

Description

technical field [0001] The invention relates to the field of clamps for plate-shaped objects, in particular to an adjustable microwave circuit board clamp. Background technique [0002] In high-frequency circuits, microwave circuit boards are usually small in size and indeterminate in shape so that it is difficult to perform fixed tests on them; when testing microwave circuits with instruments, butt cables may cause SMA connectors to fall off, and due to soldering. The error is also more obvious. [0003] The present invention can achieve the purpose of fixing microwave circuit boards of different shapes and making them multi-point grounded by adjusting the position of the metal slider and the pressing piece; the SMA connector is fixed on the metal slider, which effectively avoids the joint falling off when the cable is connected The situation; the SMA connector and the circuit board adopt a crimping method, which effectively avoids the error caused by welding during the te...
