Embodiment Construction

[0028] With reference to the drawings in the specification, a T / R component automated test system structure includes pressure plate 1, thermal pad 2, cold plate 3, upper cover 4, frame 5, A panel 6, side cover 7 (2 pieces), and B panel 8, bottom plate 9, device mounting board 10.

[0029] Such as Figure 1 ~ Figure 3 As shown, during assembly, the thermal pad 2 is attached to the upper surface of the cold plate 3, and then the T / R assembly 11 is installed on the upper surface of the thermal pad 2, and the positioning boss 14 of the cold plate 3 is used to achieve positioning, and then the pressure plate 1 Install it on the T / R assembly 11. Fix the pressure plate 1 on the positioning boss 14 of the cold plate 3 with screws. The tightening torque is about 30cN.m. At this time, the thickness of the thermal pad is compressed from 0.38mm to 0.35mm. Then fix the above components on the upper cover 4. Insert the KK connector 12 from the lower surface of the cold plate 3 through the t...

Abstract

The present invention discloses a T/R module automatic test system structure. The structure comprises a pressing plate, a heat conduction pad, a cold plate, an upper cover plate, a frame, an A panel,a side cover plate, a B panel, a bottom plate and a device installation plate. A standard piece is employed to connect with the cold plate, the heat conduction pad, a T/R module, the pressing plate and the upper cover plate, an upper end of a KK joint is inserted into the T/R module through circular holes of the upper cover plate and the cold plate, and the test system is inserted into the lowerend of the KK joint to form an access. Through the dimensional tolerance design of the cold plate, the KK joint and the T/R module, the high-precision mutual insertion is achieved to ensure the electrical performances. The test system is installed on the installation plate. The A panel, the B panel, the side cover plate and the bottom plate are connected with an assembling structure on the frame to achieve the automatic test function of the T/R module. The system is compact in structure, convenient to implement and low in cost, simulates the T/R module working scene in high precision, improvesthe test efficiency of the T/R module and ensures the test reliability.

Description

Technical field [0001] The invention relates to a test system structure, in particular to a T / R component automated test system structure. Background technique [0002] The multi-channel T / R module (T / R module for short) is the key component of the phased array landing sensor. Its performance directly affects the measurement performance of the whole machine. Therefore, it is necessary to conduct a comprehensive performance test on the T / R module before installation. , Including testing of amplitude and phase control accuracy. However, the T / R module is a multi-channel transceiver system. Depending on the size of the phased array array, the number of transceiver channels can reach hundreds or even thousands, and each channel needs to be tested for hundreds of working conditions. The measurement workload is very large. Large, the manual test efficiency is very low, and the reliability is poor. [0003] T / R components will generate a lot of heat during the test, and it is necessary ...
