Description

Technical Field

[0001] The present application relates to the technical field of vibration test fixtures, and in particular to a vibration fixture for a multi-channel TR assembly. Background Art

[0002] In the microwave field, TR components are the core of phased array radar systems. Tile-based components, a novel implementation of TR components, utilize three-dimensional stacking technology to vertically stack multiple microwave chips or circuits, enabling vertical signal transmission along the Z-axis. Compared to traditional "brick-like" TR components, tile-based components offer significant advantages, including high integration, compact size, thinness, light weight, and ease of conformality.

[0003] To ensure that the performance of tile assemblies meets the stringent requirements of phased array radars, they are typically subjected to vibration testing. In existing designs, the tile's test signal output and input terminals are located on opposite sides of the tile, with a connector connecting the signal output cable to the tile's test signal output.

[0004] However, due to the high number of channels in tile-type modules, the signal output terminals of tile-type modules typically have numerous signal output cables and connectors. During vibration testing, the connectors of these signal output cables may swing with the vibration frequency, causing the connectors to loosen, which in turn affects the stable transmission of signals and leads to deviations in test results. Utility Model Content

[0005] In order to reduce the possibility of swinging at the joint of the signal output cable during the vibration test of the tile-type component, the present application provides a vibration tooling for a multi-channel TR component.

[0006] The present application provides a vibration tooling for a multi-channel TR assembly using the following technical solutions:

[0008] A fixing seat, on which the TR assembly is fixed by a fixing unit;

[0009] A positioning frame is mounted on the fixing seat, wherein the positioning frame presses the signal output cable against the positioning frame through a clamping unit, and the test signal output end of the TR assembly is close to the positioning frame;

[0032] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0033] The embodiment of the present application discloses a vibration tooling for a multi-channel TR assembly.

[0034] A vibration tooling for a multi-channel TR assembly includes a fixing base 1, a positioning frame 2, and a base 3. The test signal input terminal and the test signal output terminal of the TR assembly are arranged on opposite sides of the TR assembly. The TR assembly is fixed to the fixing base 1 via a fixing unit 11. The positioning frame 2 is mounted on the fixing base 1, and the signal output cable 5 is pressed against the positioning frame 2 via a clamping unit 21, and the test signal output terminal of the TR assembly is close to the positioning frame 2. The fixing base 1 is movably mounted on the base 3, and the vibration source transmits vibration to the fixing base 1 via the base 3.

[0035] When performing a vibration test on the TR component, first fix the TR component on the fixing base 1 through the fixing unit 11. Then plug the signal output cable 5 into the test signal output end of the TR component through the connector 4. Next, press the signal output cable 5 against the positioning frame 2 near the cable connector through the clamping unit 21, and plug the test signal input end of the TR component into the signal input cable. After the fixing base 1 is fixedly installed, the vibration source transmits the vibration to the TR component and the signal output cable 5 through the base 3. At this time, the signal output cable 5 is pressed against the positioning frame 2 near the cable connector. At this time, the signal output cable 5 is pressed against the positioning frame 2 near the cable connector, which reduces the possibility of relative shaking between the signal output cable 5 and the test signal output end of the TR component, and thus reduces the possibility of signal loss of the TR component during the vibration test.

[0036] Multiple mounting surfaces are provided between the mounting base 1 and the base 3, and different mounting surfaces of the mounting base 1 can be connected to the base 3. When multi-angle vibration testing of the TR component is required, the mounting base 1 can be directly connected to the base 3 through different mounting surfaces, thereby facilitating testing the impact of different vibration directions on the TR component signal transmission.

[0037] Mounting base 1 has a positioning slot for the TR assembly. Fixing unit 11 is a pressure plate mounted on mounting base 1. The pressure plate is fixed to mounting base 1 via multiple screws, pressing the TR assembly into the positioning slot to enhance its stability. The pressure plate also has a connection hole for the test signal output terminal and the signal output cable 5.

[0038] When installing the TR component, place the TR component inside the positioning groove, and use the positioning groove to position the connection hole and the TR component test signal output end to coincide with each other, so that the signal input cable can be connected to the TR component test signal output end through connector 4.

[0039] The fixed base 1 is provided with a threading channel 12 for placing the signal input cable, and a connecting groove penetrating through the inner wall of the threading channel 12 is formed on the inner wall of the threading channel 12. The connecting groove communicates with the positioning groove and the threading channel 12, and the test signal input end of the TR component can be inserted into the signal input cable in the threading channel 12 through the connecting groove.

[0040] The test signal input end of the TR component is positioned through the connecting groove. At the same time, the operator inserts the joint of the signal input cable into the test signal input end of the TR component through the connecting groove inside the threading channel 12. The relatively large space of the threading channel 12 improves the convenience of the operator's operation.

[0041] The positioning frame 2 is arranged in a U shape, and the opening of the positioning frame 2 faces the fixed base 1. At least one positioning frame 2 is provided. In the embodiment of the present application, four positioning frames 2 are provided. The clamping unit 21 is a clamping strip 23 installed on the positioning frame 2. The clamping strip 23 is fixed to the positioning frame 2 by screws, and an arc-shaped groove 24 for the signal input cable to pass through is provided between the clamping strip 23 and the positioning frame 2.

[0042] When installing the clamping strip 23, place the clamping strip 23 in the placement groove 22 for preliminary positioning, so as to facilitate the installation of the clamping strip 23 on the positioning frame 2. I

[0043] A protective sleeve 25 for protecting the signal output cable 5 is provided at the arc-shaped groove 24. The protective sleeve 25 is made of non-metallic rubber material as a whole. The protective sleeve 25 is sleeved on the signal output cable 5, so as to protect the signal output cable 5 when the clamping strip 23 and the positioning frame 2 clamp the signal output cable 5, and reduce the possibility of damage to the signal output cable 5. At the same time, the relatively large friction force between the protective sleeve 25 made of non-metallic rubber material and the signal output cable 5 also reduces the possibility of the signal output cable 5 shaking. The protective sleeve 25 has a certain elasticity, which improves the adaptability to signal output cables 5 with different diameters.

[0044] In order to facilitate placing the signal output cable 5 into the protective sleeve 25, a notch 253 for the signal input cable to be placed is provided on the protective sleeve 25. When placing the signal output cable 5, directly place the signal output cable 5 into the protective sleeve 25 from the notch 253, thereby improving the convenience of sleeving the protective sleeve 25 on the signal output cable 5.

[0045] The protective sleeve 25 comprises a sleeve body 251 and clamping blocks 252. The sleeve body 251 is cylindrical, with the clamping blocks 252 located at either end of the sleeve body 251. The clamping blocks 252 and the sleeve body 251 are integrally formed. After the protective sleeve 25 is placed over the signal output cable 5 and the clamping bar 23 secures the signal output cable 5 to the positioning frame 2, the two clamping blocks 252 clamp the two sides of the clamping bar 23, thereby facilitating the positioning of the sleeve body 251 and reducing the possibility of relative movement between the sleeve body 251 and the clamping bar 23.

[0046] The implementation principle of the vibration tooling of a multi-channel TR assembly in the embodiment of the present application is as follows:

[0047] When installing the TR assembly, place the TR assembly in the positioning groove of the fixing base 1, so that the test signal input end of the TR assembly is placed in the connection groove. Place the pressure plate on the TR assembly so that the pressure plate presses the TR assembly into the positioning groove under the action of the screw, thereby improving the working stability of the TR assembly. Then, plug the connector 4 into the test signal output end of the TR assembly through the connection hole, and plug the signal output cable 5 into the connector 4. Place the signal input cable in the threading channel 12, and plug it into the test signal input end of the TR assembly through the connection groove, thereby completing the plug-in between the TR assembly, the signal input cable, and the signal output cable 5.

[0048] When fixing the signal output cable 5, first fix the positioning frame 2 to the fixing seat 1 with screws, and place the signal output cable 5 inside the protective sleeve 25 through the notch 253 of the protective sleeve 25. Then, place the protective sleeve 25 and the signal output cable 5 together in the corresponding arc groove 24 on the positioning frame 2, and make the two clamping blocks 252 of the protective sleeve 25 clamp the positioning frame 2. Next, place the end of the clamping bar in the placement groove 22 of the positioning frame 2, position the clamping bar through the placement groove 22, and make the clamping bar be located between the two clamping blocks 252 of the protective sleeve 25, so as to complete the fixation of the signal output cable 5 near the connector position. When the signal output cable 5 shakes due to vibration testing, the possibility of relative shaking between the connector of the signal output cable 5, the connector 4 and the test signal output end of the TR component is reduced.

[0049] To perform vibration testing on a TR assembly, simply mount bracket 1 on base 3. The vibration source transmits vibrations to the TR assembly on mount bracket 1 through base 3. To perform vibration testing on a TR assembly at multiple angles, mount bracket 1 can be mounted on base 3 using the corresponding mounting surface, facilitating testing of the TR assembly in different vibration directions.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
