[0002] Microwave components refer to the most basic parts with working frequency between 300MHz and 300GHz, which are processed by special technology without changing the surface molecular structure. Microwave components are described as parts with the smallest unit with working frequency between 300M and 300GHz. Microwave components are functional parts with functions assembled by special technology from multiple components. For example, resistors, inductors, antenna plastic vibrators, VC heat spreaders, etc. are all microwave components.

[0003] In real life, when testing microwave components, corresponding fixtures are needed to clamp the components. However, the common fixture structure is relatively simple, and it is inconvenient to detect the clamping force when clamping the components. It is easy to damage the components due to excessive clamping force, and the practicality is low. Therefore, we propose a microwave component test fixture. Utility Model Content

In real life, when testing microwave components, corresponding clamps are needed to clamp the components. However, the common clamp structure is relatively simple, and it is inconvenient to detect the clamping force when clamping the components.

[0013] As a preferred solution of the utility model, the second sliding block is slidably connected to the second sliding groove, and the clamping plate is fixedly connected to the second sliding block.

[0014] The technical effect of adopting the above further solution is: through the fixed connection between the clamping plate and the second slider, the clamping plate can be driven by the second slider to slide up and down inside the second slide groove, so that components with different thicknesses can be clamped.

The bottom of the clamping plate 206 and the contact point between the fixed seat 201 and the clamping plate 206 are provided with rubber protective pads to protect the surface of the components. Threaded rods 207 are symmetrically provided near the left and right sides of the bottom of the fixed seat 201, and a spring 208 is provided at the top of the threaded rod 207, and a push rod 209 is provided at the top of the spring 208.

[0032] Example 2

[0033] like Figure 1-4As shown, the first slider 102 is slidably connected to the first slide groove 101, and the fixed seat 201 is fixedly connected to the first slider 102. Through the fixed connection between the fixed seat 201 and the first slider 102, the fixed seat 201 can slide forward and backward inside the first slide groove 101 through the first slider 102 according to the size of the components, thereby improving practicality. The screw rod 203 is rotatably connected to the fixed seat 201, the limit rod 204 is fixedly connected to the fixed seat 201, and the second slider 205 is connected to the screw rod 203 and the limit rod 204. The second slider 205 is adapted to the screw rod 203 and the limit rod 204, and the screw rod 203 can be rotated to adjust the upper and lower positions of the second slider 205, and the clamping plate 206 is used to clamp the components. The second slider 205 is slidably connected to the second slide groove 202, and the clamping plate 206 is fixedly connected to the second slider 205. Through the fixed connection between the clamping plate 206 and the second slider 205, the clamping plate 206 can be driven by the second slider 205 to move in the second slide groove 202. 2 can slide up and down inside to clamp components of different thicknesses. The threaded rod 207 is adapted to the fixing seat 201, and the push rod 209 is slidably connected to the fixing seat 201. The two ends of the spring 208 are respectively fixedly connected to the threaded rod 207 and the push rod 209. The spring 208 can be squeezed by rotating the threaded rod 207, thereby compressing the space for the push rod 209 to sink. When the user rotates the screw rod 203 to make the clamping plate 206 descend to clamp the components, the push rod 209 that is restricted from sinking will move the clamping plate 206 is supported to prevent it from continuing to descend and causing damage to components. The interior of the fixed seat 201 is symmetrically provided with limiting grooves 210 on the left and right sides of the second slide groove 202. A limiting block 211 is arranged inside the limiting groove 210. The limiting block 211 is slidably connected to the limiting groove 210. The limiting block 211 is fixedly connected to the clamping plate 206. The limiting groove 210 and the limiting block 211 can limit the clamping plate 206 during the descent process to prevent it from deflecting, thereby improving the clamping effect on components.

[0034] The working process of the utility model is as follows: when a microwave component test fixture is used to clamp microwave components, firstly, the threaded rod 207 is rotated according to the thickness of the clamped component to squeeze the spring 208. After the spring 208 is squeezed, the contraction space will be reduced accordingly. According to the length of the component, the two fixing seats 201 are pushed to make the two fixing seats 201 slide inside the first slide groove 101 through the first slider 102 until they slide to a suitable position, and the two ends of the component are respectively prevented from being separated from the two fixing seats 201 and the two clamping plates 201. 6, rotate the screw rod 203 so that the screw rod 203 drives the second sliding block 205 to slowly descend inside the second sliding groove 202. When the bottom of the clamping plate 206 contacts the push rod 209, the push rod 209 is subjected to the downward pressure and slowly sinks to compress the spring 208. When the contraction space of the spring 208 is saturated, the push rod 209 will not be able to continue to sink, thereby preventing the clamping plate 206 from continuing to descend. The clamping work of the components is completed by the relatively soft rubber protective pad, which prevents the components from being damaged due to excessive clamping force, and effectively improves the practicality.
