Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency testing, in particular to a patch-type radio frequency test calibration component. Background Technique

[0002] In the field of radio frequency testing, in order to ensure the reliability of test data, calibration before testing is essential. For the calibration of a network analyzer, it can be divided into a mechanical calibration component and an electronic calibration component. For the calibration of board-end testing, neither the mechanical calibration component nor the electronic calibration component used by the network analyzer is applicable to the calibration of board-end testing.

[0003] Currently, the most commonly used method is to use OPEN and SHORT radio frequency boards. After surface-mounting the radio frequency device to be tested, it is used as a calibration component. The calibration data is accurate and the reliability is the highest. However, it is necessary to make the radio frequency board the same size as the board end, which not only limits its versatility but also significantly increases the cost burden. The durability is limited by the radio frequency device to be tested, resulting in a relatively short lifespan and the need to frequently replace the radio frequency device to be tested. Or only a short-circuit device is used for board test calibration, but it is easy to cause inaccurate data and poor stability. To solve these problems, the utility model proposes a patch-type radio frequency test calibration component. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a patch-type radio frequency test calibration component.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A patch-type radio frequency test calibration component, including a housing. A connection shell is fixedly connected to the upper surface of the housing. An insulator is inserted into the connection shell. A limiting groove is opened on the lower surface of the insulator. A limiting block is inserted into the limiting groove. A radio frequency board is fixedly connected to the lower surface of the limiting block. Rotating seats are fixedly connected to both sides of the lower surface of the housing. A clamping mechanism is fixedly connected to one side of the rotating seat. A rotating rod is rotatably connected to the inside of the rotating seat.

[0007] As a further improvement of the utility model, the clamping mechanism includes a mounting seat fixedly connected to one side of the rotating seat. One side of the inner wall of the mounting seat is fixedly connected with a return spring. One end of the return spring is fixedly connected with a movable block. The movable block is movably connected to the inside of the mounting seat. A first trapezoidal clamping block is fixedly connected to the front surface of the movable block.

[0008] As a further improvement of the utility model, a sliding groove is opened on the lower surface of the mounting seat. A dial is fixedly connected to the lower surface of the movable block. The dial is movably connected to the sliding groove.

[0009] As a further improvement of the present utility model, a second trapezoidal clamping block adapted to the first trapezoidal clamping block is fixedly connected to the surface of one end of the rotating rod.

[0010] As a further improvement of the present utility model, welding panels are fixedly connected to the surfaces of both rotating rods.

[0011] As a further improvement of the present utility model, protective soft pads are fixedly connected to the upper surfaces of both welding panels, and the protective soft pads are made of rubber.

[0012] Beneficial effects of the present utility model:

[0013] By providing a radio frequency board, during use, the device adopts a patch-type radio frequency test calibration component, eliminating the need to remake the radio frequency board. Utilizing the product's own PCB board can ensure the accuracy and reliability of calibration data. At the same time, with the core component being the radio frequency board, the durability of the device is improved, reducing the need for frequent replacement of the device under test, enhancing versatility, increasing lifespan, and reducing the overall usage cost.

[0014] By providing a clamping mechanism, during use, through the clamping structure of the first trapezoidal clamping block and the second trapezoidal clamping block, and in conjunction with the automatic reset mechanism of the rotating rod and the return spring, the installation and disassembly process of the radio frequency board and the insulator becomes extremely simple and fast. This not only improves work efficiency but also reduces the risk of damage caused by frequent disassembly and assembly. At the same time, a stable mechanical locking structure is formed, ensuring a firm connection between the radio frequency board and the housing, effectively preventing loosening or detachment of the device during use due to vibration or external forces, and guaranteeing the stability and reliability of the device.

[0015] By providing a housing, during use, after the device is assembled, the entire device can be quickly tested and calibrated. Since the assembly process is simple and fast, users can disassemble and assemble the device at any time according to needs, facilitating multiple rounds of testing or adjustment to meet different application requirements. When internal components of the device need maintenance or replacement, users can easily complete it without the need for professional tools or complex operations, thereby reducing maintenance costs and time costs.

[0016] In summary, through innovative structural design, the present utility model realizes the quick and convenient assembly and disassembly of the radio frequency board and the insulator, while ensuring the stability of the connection and the overall performance of the device.
