Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a testing device for testing micro connectors. Background Technology

[0002] As people's living standards continue to improve, they have higher requirements for the functionality and size of electronic products. They want more features while also demanding smaller, more portable sizes. One method is to reduce the size of connectors within electronic products to minimize their space. Smaller connectors mean smaller pins and smaller spacing. When the pin spacing is too small, conventional testing probes and methods become unsuitable, requiring the use of microprobes. Microprobes have higher requirements for pinhole size, and traditional testing equipment and manual testing methods can no longer meet current testing requirements. Utility Model Content

[0058] Preferably, the microneedle module 2 includes an upper needle block 201 and a lower needle block 202;

[0060] For commonly available miniature connectors with a test point spacing of 0.35mm, using 0.28mm probes and Trinitron probe blocks, the existing solutions are no longer sufficient to meet the current testing requirements, particularly for 0.3mm test point spacing miniature connectors. Specifically: 1) standard probes cannot accommodate the pin insertion of miniature connectors with a 0.3mm test point spacing; 2) standard materials cannot meet the requirements for pin hole drilling with the 0.3mm test point spacing miniature probe 203; and 3) the accuracy and stability of miniature connector testing cannot be guaranteed. This device utilizes the Leeno GN151AA miniature probe 203, which can perform pin insertion testing with a 0.3mm test point spacing. The probe block is made of a ceramic-PEEK composite material, ensuring strong pin hole size stability, burr-free operation, good wear resistance and ductility, stable electrical characteristics, thermal stability, and cost-effectiveness. The micro-needle module 2, composed of the Leeno GN151AA miniature probe and the ceramic-PEEK probe block, ensures the accuracy and stability of the test.

[0061] Before testing, place the product in the corresponding position, scan the QR code on the product, and press the start buttons on both sides (set on the electrical control box 1, which serves as the base, according to requirements) to start the test. When the test starts, the pressure plate module 4 begins to press down. After it is pressed into place, the USB-C module 6 and SIM card module 7 on the right side begin to be inserted into the corresponding interfaces of the product, and the functional test can begin.

[0062] The pressure plate 403 presses down, causing the carrier plate 501 to press down. The pins between the carrier plate 501 and the needle plate 502 ensure alignment accuracy, while four linear bearings 503 ensure perpendicularity. The linear bearings include bearing sleeves set on the needle plate 502 and bearing pins set on the carrier plate 501.

[0063] The micro-needle module 2 is a floating module. When the pressure plate 403 continues to press down, the micro connector at the beginning of the product begins to contact the micro-needle module 2. The positioning and floating of the micro connector on the micro-needle module 2 ensure the alignment accuracy between the micro probe 203 and the test point on the micro connector.

[0064] In this embodiment, the Leeno GN151AA miniature probe 203 is used. The probe tip and tail size is only 0.1mm, the tube size is only 0.21mm, the recommended stroke is 0.65mm, the tip is pointed, the penetration is strong and the probe is resistant to contamination. This probe has good conductivity, good durability, high hardness, low impedance and wear resistance.

[0065] In this embodiment, the microneedle module 2 is mainly divided into an upper needle block 201 and a lower needle block 202. The two needle blocks are positioned by their shape, with a single-sided spacing of 0.01mm to ensure alignment accuracy. The spring in the middle makes them float. First, the micro connector is positioned with the upper needle block 201 to ensure accurate alignment before the probe is released.

[0066] The lower needle block 202 has a needle hole size of 0.13mm corresponding to the needle head and needle tail, and a minimum spacing of 0.17mm between the needle holes. The needle tube has a needle hole size of 0.22mm, and a minimum spacing of 0.08mm between the needle holes. For this purpose, a composite material of ceramic and PEEK is used, which can meet the processing requirements of this needle hole. Moreover, the needle hole has strong dimensional stability, no burrs, and good wear resistance and ductility, which can meet the testing requirements.

[0067] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
