AI Technical Summary

Technical Problem

Existing PCB test probes are difficult to fix stably when testing at multiple test points, and are prone to displacement and shaking, which affects test accuracy and reliability.

Method used

The probe sleeve is fixed by threaded connection between guide plates, combined with the structure of cylinder, guide column and pressure plate. Vibration is damped by guide block and silicone ring, and the probe is fixed by spring and limit block to ensure the stability of the probe during the test.

Benefits of technology

It effectively prevents probe deviation and shaking during the testing process, improving the stability and accuracy of the test, and supporting fast, reliable PCB loading/unloading and repeat testing.

Abstract

This utility model relates to the field of PCB probe technology, and more particularly to a PCB test probe anti-offset fixture. The technical solution includes a guide plate one and a guide plate two. The lower surface of the guide plate one is fixedly connected to the guide plate two via a fixing post. The surface of the guide plate one has evenly distributed screw holes one through it. The guide plate two has screw holes two corresponding to the screw holes one. A needle sleeve is threadedly installed between the screw holes one and the corresponding screw holes two, and a probe is slidably connected inside the needle sleeve. This utility model, through the cooperation between the guide plate one and the guide plate two, fixes both ends of the needle sleeve to the two guide plates, thereby making the needle sleeve more stable. Simultaneously, the threaded engagement between the contact surfaces of the needle sleeve and the guide plates one and two further stabilizes the needle sleeve, and makes replacement more convenient and quick. After the needle sleeve is stably fixed, the offset and shaking of the probe passing through the needle sleeve during testing can be reduced.
