Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, specifically to a high-frequency, high-speed test fixture for automatic machine tool testing. Background Technology

[0002] In the electronic manufacturing process, high-frequency and high-speed test sockets are used to test the electrical performance and electrical connections of components. Through precise measurement, they ensure the functional reliability of circuit boards. In various stages of electronic manufacturing, such as wafer testing and chip packaging verification in the semiconductor industry, connecting radio frequency devices and test instruments in the communication equipment field, and incoming material inspection, rework inspection and IC sorting in the consumer electronics field, they can significantly improve product yield and production efficiency.

[0003] Existing testing methods struggle to quickly and accurately construct stable and effective test circuits between test probes and workpiece pins. During test preparation, operators may need to invest significant time repeatedly adjusting the probe positions. Furthermore, the test socket lacks effective protection mechanisms for high-frequency probes, making them more susceptible to damage during use. Frequent contact with the workpiece, coupled with potential external impacts or insufficient fixation, easily leads to bending, breakage, and wear. This frequent damage forces operators to replace probes frequently, directly increasing testing costs and reducing production efficiency due to extended downtime. Moreover, the inability to maintain consistent contact between the high-frequency probes and workpiece pins during testing frequently results in poor contact and signal interference, leading to significant fluctuations in test data and inaccurate results. This severely impacts the reliability of workpiece quality assessment and significantly reduces the stability and credibility of the test. Utility Model Content

[0022] As attached Figure 1 To be continued Figure 7 As shown: This embodiment provides a high-frequency, high-speed testing base for automatic testing machines, including a base 1, a top cover 2 on the top of the base 1, a lower needle plate 3 embedded in the bottom of the inner cavity of the base 1, a high-frequency needle 4 threadedly connected to the top of the lower needle plate 3, an upper needle plate 5 on the top of the lower needle plate 3, a float plate 6 on the top of the upper needle plate 5, and through grooves 14 on both the front and rear sides of the top cover 2. A first steel pin 9 is provided in the inner cavity of the through groove 14, with both ends of the first steel pin 9 penetrating to the outer side of the top cover 2. A snap fastener 7 is rotatably connected to the surface of the steel pin 9. Two grooves 8 are formed on the surface of the snap fastener 7. A second steel pin 10 is provided on the front and rear sides of the inner cavity of the base 1. Both ends of the second steel pin 10 penetrate to the outside of the base 1. Two snap fastener swing arms 11 are sleeved on the surface of the second steel pin 10. One side of the snap fastener swing arm 11 penetrates to the inner cavity of the groove 8. A first steel pin 9 is provided on the left side of the snap fastener 7. One end of the first steel pin 9 penetrates to the right side of the snap fastener 7, and the snap fastener swing arm 11 is sleeved on the surface of the first steel pin 9.

[0023] Specifically, two limiting grooves 12 are provided on both sides of the base 1, and a limiting block 13 is provided in the inner cavity of the limiting groove 12. The top of the limiting block 13 is fixedly connected to the upper cover 2.

[0024] In this embodiment, the use of the limiting groove 12 and the limiting block 13 together limits the base 1, thereby improving the stability of the base 1 when it moves.

[0025] Specifically, there are several high-frequency needles 4, with the top end of the high-frequency needle 4 extending to the top of the float plate 6 and the bottom end of the high-frequency needle 4 extending to the bottom of the lower needle plate 3.

[0026] In this embodiment: by setting the high-frequency needle 4, the high-frequency needle 4 can contact the workpiece pin to form a test circuit, thereby facilitating the testing of the workpiece.

[0027] Specifically, the surface of the upper needle plate 5 is provided with through holes that are compatible with the high-frequency needles 4, and the through holes are distributed at equal intervals.

[0028] In this embodiment, the through hole serves to protect the high-frequency needle 4, making it less prone to damage.

[0029] Specifically, both sides of the front and back surfaces of the base 1 and the top cover 2 are provided with arc surfaces, and the arc surfaces are smooth.

[0030] In this embodiment, the use of curved surfaces saves manufacturing costs and reduces the financial burden on users.

[0031] The working principle and usage process of this utility model are as follows: The user moves the upper cover 2 downwards, and the upper cover 2 drives one side of the buckle 7 to move downwards through the first steel pin 9. When the buckle 7 moves, it will make an arc-shaped movement with the first steel pin 9 as the center. At the same time, the buckle 7 will drive the first steel pin 9 to move. The first steel pin 9 will drive the buckle swing arm 11 to make an arc-shaped movement with the second steel pin 10 as the center. When the other side of the buckle 7 enters the inner cavity of the through groove 14, the workpiece to be tested can be placed on the top of the floating plate 6. After the workpiece is placed, the upper cover 2 is moved upwards. The upper cover 2 drives the buckle 7 to make an arc-shaped movement, so that the buckle 7 contacts the top of the workpiece. The buckle 7 drives the workpiece to press down, so that the high-frequency needle 4 contacts the workpiece pin, forming a test circuit.
