Description

Technical Field

[0002] Radio Frequency (RF) is the abbreviation of Radio Frequency, which means the electromagnetic frequency that can be radiated into space. The frequency range is from 300kHz to 300GHz. Radio frequency is radio frequency current, abbreviated as RF. It is the abbreviation of high-frequency alternating electromagnetic waves. Alternating current that changes less than 1000 times per second is called low-frequency current, and alternating current that changes more than 10,000 times per second is called high-frequency current. Radio frequency is such a high-frequency current.

[0003] During the use of RF devices, multiple positions of the RF devices may be connected to multiple RF connectors. The RF connectors are made of copper, which can effectively reduce the RF loss during transmission. However, the RF devices will be tested during the clamping process, so the RF devices need to be flipped for testing. When the existing fixture is flipped, the RF device needs to be removed. Therefore, a low-loss RF device test fixture is proposed to solve the above problem. Utility Model Content

[0024] like Figure 1 and Figure 2 As shown, the right end of the threaded rod 4 is rotatably connected to the right inner wall of the slide groove 2 through a bearing, and the bottom of the movable plate 5 is set to be slidably connected to the bottom of the slide groove 2. When the threaded rod 4 rotates, the movable plate 5 will rotate, and the bottom of the movable plate 5 is slidably connected to the bottom of the slide groove 2 to prevent the movable plate 5 from angular displacement.

[0025] like Figure 1 and Figure 2As shown, the right end of the rotating shaft 702 passes through the movable plate 5 and extends to the right side of the movable plate 5. The rotating shaft 702 is rotatably connected to the movable plate 5 through a bearing. The handle 703 is moved, and the handle 703 rotates the gear 701 through the rotating shaft 702, and the gear 701 rotates.

[0026] like Figure 1 and Figure 2 As shown, there are two card slots 709 on the left clamping plate 708, and three card slots 709 on the right clamping plate 708, so that the left side of the RF device is clamped with the left card slot 709, and the right card slot 709 is clamped with the right side of the RF device.

[0027] like Figure 2 and Figure 3 As shown, the gear 701 is meshed with the right elliptical gear 704, and a clamping rod is fixedly installed on the opposite side of the two elliptical gears 704. The two clamping rods slide inside the through hole 705, and the baffle 707 is pressed downward by the spring 706, so that the right elliptical gear 704 is always meshed with the gear 701.

[0028] like Figure 2 and Figure 3 As shown, the bottoms of the two baffles 707 are in contact with the tops of the two clamping rods, and the two clamping rods are in contact with the opposite sides of the movable plate 5 and the fixed plate 6 respectively.

[0029] When implementing, follow these steps:

[0030] 1) First, snap the left side of the RF device into place with the left slot 709;

[0031] 2) Then start the motor 3 to drive the moving plate 5 to slide to the left inside the slide slot 2, so that the right side slot 709 is engaged with the right side of the radio frequency device;

[0032] 3) Turn the handle 703 again to rotate the gear 701;

[0034] In summary, the low-loss RF device test fixture is provided with a flip structure 7. When testing the RF device, the RF device is clamped between the two clamping plates 708, and then the handle 703 is turned. The handle 703 rotates the gear 701 through the rotating shaft 702. The gear 701 rotates, driving the elliptical gear 704 on the right to rotate. Then, both elliptical gears 704 rotate. During the rotation process, the levers of the elliptical gears 704 opposite to each other move. At this time, the two baffles 707, under the action of the spring 706, move the two elliptical gears 704. The wheel 704 is pressed downward to keep the gear 701 engaged with the right elliptical gear 704 at all times, thereby completing the flipping function of the RF device. The low-loss RF device test fixture is equipped with a motor 3. When the RF device is tested, the left side of the RF device is engaged with the left slot 709, and then the motor 3 is started. The motor 3 drives the threaded rod 4 to rotate, and drives the movable plate 5 to slide to the left inside the slide groove 2, so that the right slot 709 is engaged with the right side of the RF device, and then the RF device is flipped, thereby completing the detection function of the RF device.
