Description

Technical Field

[0001] This utility model relates to the field of radio communication equipment technology, and in particular to a testing fixture for a TR component. Background Technology

[0002] In radar systems, the radar transceiver (TR) module is one of the core components. It is responsible for transmitting high-power radar signals and receiving echo signals reflected from targets. With the continuous advancement of semiconductor and microwave technologies, the integration level of TR modules is increasing, and the number of radar array elements is also increasing, making the detection of TR modules more and more difficult, both in terms of the complexity of the detection methods and the increase in detection time.

[0003] To determine whether the performance of a TR component meets design specifications, it needs to be tested. However, a single TR component has multiple testing points, and each connection and configuration takes time, increasing the testing time and labor costs for a single TR component. When facing batch testing, the preparation time for each component and the overall testing time become even longer, affecting production and R&D efficiency. In addition, during point-to-point testing, temperature differences exist at different points and in different test areas due to time constraints, and temperature has a significant impact on the performance of TR components, thus affecting the accuracy of test results.

[0004] Therefore, it is necessary to improve one or more of the problems existing in the above-mentioned related technical solutions.

[0035] The clamp 200 is disposed on the platform 100, and the clamp 200 is used to longitudinally press the TR assembly;

[0036] The indexing pin 300 passes through the first positioning hole 101 on the front of the platform 100 to position the TR component 600 placed in the first through hole in a first direction, and the indexing pin 300 passes through the first positioning hole 101 on one side of the platform 100 to position the TR component placed in the first through hole in a second direction.

[0037] The adapter plate 400 is disposed below the first through hole. The adapter plate 400 is provided with an array of test contacts 401. Each test contact 401 is connected to an RF line 402 below the adapter plate 400. The RF line 402 is electrically connected to the detection instrument.

[0038] The pressure plate 500 is disposed below the adapter plate 400. The pressure plate 500 is provided with an array of second through holes 501, which are used to allow the radio frequency line 402 to pass through.

[0039] The aforementioned testing fixture for TR component 600, on the one hand, facilitates convenient and simple operation when positioning and clamping the test piece through the cooperation of the indexing pin 300 and the clamp 200, thereby improving work efficiency; on the other hand, by using structural positioning, multiple testing points can be efficiently positioned and multiple channels can be tested at once, improving the testing efficiency in the batch production process of TR component 600 and reducing the impact of temperature on the testing results.

[0040] The following will refer to Figures 1 to 5 The various parts of the detection fixture for the TR component described in this example embodiment will be explained in more detail.

[0041] In one embodiment, the TR component 600 has a reserved ball-planting point. During testing, the test contact 401 contacts the reserved ball-planting point of the TR component 600. The platform 100 has a connection hole 102 on its lower surface, the adapter plate 400 has a third through hole 403, and the pressure plate 500 has a fourth through hole 502. A connector connects the platform 100, the adapter plate 400, and the pressure plate 500 through the fourth through hole 502, the third through hole 403, and the connection hole 102, and is positioned below the first through hole. It should be understood that the adapter plate 400 is connected to the lower surface of the platform 100, and its connection position is below the first through hole. When the TR component 600 is placed in the first through hole, the ball-planting point of the TR component 600 contacts the test contact 401 of the adapter plate 400. The pressure plate 500 is positioned below the adapter plate 400. When the clamp 200 clamps the TR assembly 600 longitudinally, the pressure plate 500 provides support.

[0042] In one embodiment, the platform 100 has a second positioning hole 103, the adapter plate 400 has a third positioning hole 404, and the pressure plate 500 has a fourth positioning hole 503. Positioning elements pass through the fourth positioning hole 503, the third positioning hole 404, and the second positioning hole 103 to position the pressure plate 500, the adapter plate 400, and the platform 100. It should be understood that the second positioning hole 103 on the platform 100, the third positioning hole 404 on the adapter plate 400, and the fourth positioning hole 503 on the pressure plate 500 define the position of the adapter plate 400, ensuring the positional accuracy of the test contact 401 on the adapter plate 400. This ensures that after the TR assembly 600 is positioned, the reserved ball-planting point on the TR assembly 600 makes precise contact with the test contact 401 on the adapter plate 400, ensuring the accuracy of data detection.

[0043] In one embodiment, the first through hole is a square through hole that matches the square outline of the TR component 600. It should be understood that the square through hole matches the square outline of the TR component 600, and the TR component 600 is placed within the square through hole for easy clamping and positioning.

[0044] In one embodiment, the two adjacent inner surfaces of the square through hole are both positioning surfaces, and the two positioning surfaces correspond to the first positioning hole 101 on the front side of the platform 100 and the first positioning hole 101 on one side of the platform 100, respectively. It should be understood that the indexing pin 300 passes through the first positioning hole 101 on the front side of the platform 100 and engages with the positioning surface of one inner surface of the corresponding square through hole to position the TR component 600 placed in the first through hole in a first direction. The indexing pin 300 passes through the first positioning hole 101 on one side of the platform 100 and engages with the positioning surface of one inner surface of the corresponding square through hole to position the TR component 600 placed in the first through hole in a second direction.

[0045] In one embodiment, the form and position tolerance between the two positioning surfaces is ±0.02mm. The form and position tolerance between the positioning surface and the second positioning hole 103 is ±0.02mm. It should be understood that the TR component 600 has a reserved ball-planting point that contacts the test contact 401 during testing, ensuring that the form and position tolerance between the positioning surfaces is ±0.02mm, and the form and position tolerance between the positioning surface and the second positioning hole 103 is ±0.02mm. This ensures the accuracy of the contact between the reserved ball-planting point and the test contact 401 during testing, guaranteeing accurate detection.

[0046] In one embodiment, the connector is a screw. It should be understood that the connector is a screw, and the fourth through hole 502 is a countersunk hole, which facilitates installation and improves installation efficiency.

[0047] It should be understood that the clamp 200 is disposed on the platform 100 and is used to longitudinally press the TR component 600. The specific structure of the clamp 200 is not limited here.

[0048] It is also important to understand that a support frame is provided under the platform 100. The support frame is used to support the platform, and the specific structure of the support frame is not limited here.

[0049] The tooling testing process:

[0050] During testing, connect the RF cable 402 to the testing instrument, place the TR component 600 at the first through hole, and lock the indexing pins 300 to tighten the TR component 600, ensuring it is flush against the positioning edge on the inner side of the first through hole. Then, tighten the clamp 200 to ensure the TR component 600 is firmly attached to the adapter plate 400, maintaining appropriate clamping force to avoid damaging the contacts while ensuring good contact. The ball-planting point on the TR component 600 will make complete contact with the test contact 401 on the adapter plate 400. Data is measured and recorded using the testing instrument. After testing, open the clamp 200, unlock the indexing pins 300, remove the TR component 600, and continue testing the next device under test.
