Abstract

The invention provides a SMP-to-SMA adapter alignment plugging structure and a plugging method, and belongs to the field of the microwave testing. The plugging structure comprises a base, a hollow rod, a compass, a coaxial cable and a spring; a stepped hole is arranged on the base, a positioning groove is arranged at an outer end of a small-diameter hole of the stepped hole; the hollow rod penetrates through the stepped hole; a limiting circular truncated cone in sliding matching with a large-diameter hole of the stepped hole is arranged at one end, and the other end extends out from the small-diameter hole of the stepped hole; the compass is located at the external of the base and connected with the other end of the hollow rod, and a limiting part propped against the end surface of the positioning groove is arranged on the compass; the coaxial cable penetrates through center holes of the compass and the hollow rod; a SMP adapter is arranged at one end of the coaxial cable, and a SMA adapter is arranged at the other end; the spring is sleeved on the hollow rod and compressed between the limiting circular truncated cone and the small-diameter hole of the stepped hole. The plugging between the SMP adapter and a SMP contact of a microwave module is realized through the elastic force of the spring, and the problems that the alignment is inaccurate and the contact is damaged due tomanual error are reduced.

Description

technical field [0001] The invention belongs to the technical field of microwave testing, and more specifically relates to an alignment plugging structure and a plugging method of an SMP-to-SMA adapter. Background technique [0002] At present, there are many kinds of output and input ports of microwave components, and the high-frequency parts are more common in the form of SMA, BMA, and SMP. Some types of SMP adapters are widely used because of their high microwave frequency transmission, semi-locking structure to ensure signal stability, and blind-mating structure to facilitate component connection. When microwave components with SMP adapters are tested for electrical performance in the laboratory, because the interface of the test instrument is in the form of SMA, in order to cascade with the instrument for testing, it needs to be connected to the instrument through an SMP to SMA adapter. [0003] When the frequency of the microwave signal is high, the jitter of the adap...
