Description

Technical Field

[0001] This utility model relates to the field of test fixture technology, and in particular to a TR component test fixture. Background Technology

[0002] With the advancement of semiconductor technology, especially the rapid development of 5G and phased array technologies in recent years, the phased array communication market has been expanding year by year, with the demand for multi-beam T / R components increasing daily. A T / R (Transmitter and Receiver) component refers to the part between the radio frequency (RF) and antenna in a wireless transceiver system; that is, a wireless transceiver system is formed by connecting one end of the T / R component to the antenna and the other end to the intermediate frequency (IF) processing unit. To ensure that the T / R component meets product quality requirements, it is necessary to adjust and test the T / R component.

[0003] Chinese utility model patent (authorization announcement number: CN221174738U, title: A multi-beam T / R module test fixture) includes a base, a first connector seat fixed on the base, a test connector fixed on the first connector seat, a second connector seat slidably disposed on the base, and a test connector fixed on the second connector seat. The test connectors on the first and second connector seats are arranged opposite to each other. A push-pull clamp is provided on the side of the second connector seat away from the first connector seat. A module mounting seat is also slidably disposed on the base between the first and second connector seats. The module mounting seat has a mounting groove adapted to the width of the test module. Both ends of the module mounting seat in the width direction are provided with clamping clamps for pressing the test module. This utility model eliminates the need for manual positioning during insertion, avoids connector deformation, and eliminates the need for repeated operations, resulting in high docking efficiency. The ingenious design eliminates the need for additional push-out operations and is suitable for testing modules with multiple connectors, especially multi-beam T / R modules. However, after testing, the test module needs to be manually removed, which can easily cause static electricity and interfere with the test module. Utility Model Content

[0022] like Figure 1 and 2 As shown, a TR component test fixture includes a base plate 1, a top plate 2, and support columns 3. The base plate 1 and the top plate 2 are fixedly connected by the support columns 3. There are four support columns 3, distributed at the four corners of the base plate 1. A hand-cranked lifting platform 4 is installed on the base plate 1, and a test box 5 is placed on the hand-cranked lifting platform 4. The support columns 3 pass through the test box 5, which is used to accommodate connectors. An ejector is detachably installed on the top of the test box 5 (removed during testing and reinstalled after testing). A mounting groove 6 is provided on the top plate 2 for placing the component to be tested. 19. The bottom of the mounting slot 6 is provided with several insertion through holes 7, which penetrate the top of the test box 5. The pin of the test piece 19 passes through the insertion through holes 7. The bottom of the slot next to the insertion through holes 7 is provided with an ejection channel 8, which is used for ejection. The top plate 2 can also be detachably installed with a pressure plate 9 covering the mounting slot 6. This utility model does not require manual positioning during insertion, avoids joint deformation, and improves docking efficiency during testing. At the same time, the test piece 19 is taken out through the ejection, avoiding electrostatic interference with the test piece.

[0023] In this embodiment, as Figure 1 and 2 As shown, the ejector is a square frame, and an ejector rod 10 is fixed to the top of the square frame. The ejector rod 10 can be inserted into the ejector channel 8. The top of the test box 5 is provided with a T-shaped groove 11. A T-shaped block 12 is slidably installed in the T-shaped groove 11. The T-shaped block 12 is fixed to the bottom of the square frame. A positioning structure is also provided on the T-shaped block 12. The positioning structure can quickly install the ejector into place. The cooperation between the T-shaped groove 11 and the T-shaped block 12 avoids the ejector from shifting during the lifting and lowering of the hand-cranked lifting platform 4, which would affect the ejection of the test piece 19.

[0024] In this embodiment, as Figure 1 and 2 As shown, a pair of limiting blocks 13 are fixed on the base plate 1, and the hand-cranked lifting platform 4 is located between the pair of limiting blocks 13. The limiting blocks 13 are used to limit the descent height of the test box 5, which can effectively reduce the retraction stroke of the hand-cranked lifting platform 4, meet the requirement of a shorter stroke when the connector is separated, and improve efficiency.

[0025] In this embodiment, as Figure 1 and 2 As shown, a reinforcing rod 14 is fixed inside the test box 5. The reinforcing rod 14 is used to connect the top and bottom of the test box 5, thereby reducing the risk of deformation of the test box 5 during use by increasing the strength of the test box 5.

[0026] In this embodiment, as Figure 1-3 As shown, the positioning structure includes a spring 15 and a steel ball 16. A round hole 17 is provided at the bottom of the T-shaped block 12. The spring 15 is compressed and installed in the round hole 17 through the square frame. The end of the round hole 17 away from the top plate 2 tapers. The steel ball 16 is stuck at the taper end of the round hole 17. A semi-circular groove 18 is provided at the bottom of the T-shaped slide 11. The T-shaped block 12 is locked by popping the steel ball 16 into the semi-circular groove 18. The sound made by the steel ball 16 popping into the semi-circular groove 18 can quickly determine whether the ejector is installed in place.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
