Description

Technical Field

[0001] This utility model relates to the field of radio frequency probe holder technology, specifically a highly stable radio frequency test probe holder structure. Background Technology

[0002] The contacts of RF probes are made of beryllium-copper, and the earliest RF probe technology was very different from today's tools. Later, engineers made breakthroughs in probe technology, which determined the basic requirements and working principle of RF probes. RF probes play an important role in almost every stage of the RF product lifecycle. By using RF probes, people can measure the true characteristics of RF components at the chip level. RF probes need to be supported and placed in place when in use. Using a probe holder makes it easier to use RF probes.

[0003] According to Chinese patent CN216387129U, a high-stability RF test probe holder structure is described. The rotating plate can be rotated by a rotating post located in the middle, and then fixed with bolts. A mounting block on the upper surface of the rotating plate matches a mounting groove on the lower surface of the fixed plate, thus mounting the rotating plate to the fixed plate. When the rotating plate rotates, it drives the fixed plate to rotate, adjusting the angle of the fixed plate and allowing the probe to operate at different angles. The rotation of the mounting rod causes a connecting plate connected to its end to move downwards within the fixed groove. A stabilizing suction cup is fitted to the bottom of the connecting plate via a mounting post. As the connecting plate descends, the stabilizing suction cup contacts the mounting surface, improving the stability of the mounting plate. A gravity block inside the connecting plate further enhances the stability of the mounting plate and facilitates probe operation.

[0004] When installing and adjusting the probes, the stability of the mounting rod connection inside the mounting plate is poor, especially when the suction cup and the gravity block are used together, which is prone to shaking after connection. The fixed base has a certain volume and is adjusted by rotating plate and rotating column, which is not conducive to improving the stability of rotation. Therefore, a high-stability RF test probe base structure is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a highly stable radio frequency test probe holder structure. It has advantages such as stronger stability of the fixed base when adjusting the angle, and more reliable fixing of the mounting plate, making it less prone to loosening. It solves the problems of poor stability of the mounting rod connection inside the mounting plate, especially the use of suction cup and gravity block, which is prone to shaking after connection. It also solves the problem that the fixed base, due to its certain volume, uses a rotating plate and rotating column for adjustment, which is not conducive to improving the stability of rotation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-stability radio frequency test probe holder structure, including a mounting plate, a connecting plate fixedly connected to the outer surface of the mounting plate, an adjusting plate rotatably connected to the top of the connecting plate, a fixing seat fixedly connected to the left side of the adjusting plate, and a fixing adjustment assembly provided inside the mounting plate and on the outer surface of the connecting plate.

[0007] The fixed adjustment assembly includes a guide block, which is fixedly connected to the bottom of the adjustment plate. A rotating column is fixedly connected inside the adjustment plate, and a sleeve is fixedly connected to the outer surface of the adjustment plate. A sliding rod is elastically connected inside the sleeve, and a limit post is fixedly connected to the bottom of the sliding rod. A screw is threaded inside the mounting plate, and a sliding plate is threaded to the outer surface of the screw. A snap-fit ​​post is fixedly connected to the bottom of the sliding plate.

[0008] Furthermore, the connecting plate has an annular groove inside, and the guide block is T-shaped and is slidably connected to the connecting plate through the annular groove.

[0009] Furthermore, the rotating column rotates inside the connecting plate, and the connecting plate has several limiting column holes inside, through which the limiting columns are engaged with the connecting plate.

[0010] Furthermore, the mounting plate has threaded holes, and the screw rotates inside the mounting plate through the threaded holes.

[0011] Furthermore, the sliding plate is rectangular in shape and is slidably connected to the inner wall of the mounting plate.

[0012] Furthermore, there are two snap-fit ​​posts, and the mounting plate has through holes inside, with both snap-fit ​​posts extending to the outside through the through holes.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. This high-stability RF test probe holder structure, when the mounting plate is fixed, the screw rotation can drive the sliding plate to slide, and the two locking posts will lock onto the connected mounting base. Then, by rotating the posts, the probe inside the mounting base can be adjusted in angle. When adjusting the angle, the guide block can slide inside the connecting plate to ensure higher rotational stability. Then, the sliding rod is moved to drive the limiting post to lock, thereby fixing the adjusted angle and achieving the purpose of stability testing.
