AI Technical Summary

Technical Problem

Existing connector inspection technologies, such as those described in Patent Document 1, require complex switch mechanisms in contact probes, leading to a complicated structure that is not ideal for efficient inspection.

Method used

A connector inspection jig with a simpler structure comprising a housing, first and second pins, biasing members, and a joint, along with an inspection device and position control means, allows for continuity testing by aligning terminal portions with terminal fittings and performing multiple continuity tests to detect defects.

Benefits of technology

The proposed solution enables efficient detection of improperly mated or fixed terminal fittings with a simpler structure, improving inspection accuracy and efficiency by reducing complexity and enhancing defect detection capabilities.
