AI Technical Summary

Technical Problem

When testing thin-walled data cable connectors, the existing planar clamping structure applies clamping force directly to the entire side plane, which can easily lead to crushing, deformation, or cracking of the connector sidewall, causing problems such as poor probe contact, distorted test data, and misjudgment of pass or fail.

Method used

The device employs symmetrical brackets and sliding components, combined with a meshing gear structure. The gears are driven to rotate by a button block, enabling synchronous adjustment of the opening and closing angle of the clamping components. This, along with the adjustment of the sliding component spacing, ensures that the four corners of the data cable connector are clamped between the inner walls of the symmetrical clamping components, transforming it into point clamping and avoiding stress concentration.

Benefits of technology

It effectively prevents thin-walled data cable connectors from being crushed, deformed, or cracked during clamping, ensuring stable probe contact, reducing the risk of data distortion, and improving detection accuracy.

Abstract

The invention relates to the technical field of data line detection, in particular to a jig for detecting the electrical performance of a data line. Comprising two supporting columns, symmetrical supports are arranged at the tops of the supporting columns, sliding grooves with racks are formed in the tops of the supports, and sliding assemblies are slidably connected to the supports; two second gears which are meshed with each other are arranged in the sliding assembly, and clamping assemblies are symmetrically connected to the tops of the second gears through supporting blocks; wherein one second gear is meshed with a first gear, and a button block is arranged at the top of the first gear. The button block drives the first gear to rotate, drives the two second gears to synchronously and reversely rotate, drives the clamping assemblies to synchronously adjust the opening and closing included angle, and then cooperates with the interval adjustment of the sliding assembly, so that the end corners of the data line connector are clamped between the inner walls of the included angle of the two clamping assemblies. And traditional plane-to-clamp comprehensive extrusion is converted into point-shaped clamping of opposite end corners.
