Connector Inspection Jig Guide Flat Surface Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connector inspection systems lack a guide mechanism to regulate the insertion position and attitude of the inspection jig, leading to false detection due to potential swinging or inclination of the detecting pin, especially in waterproof connectors with curved outer peripheries and uneven packing attachment surfaces, increasing inspection costs.
Innovation Solution
A connector inspection system with a reference flat surface on the connector housing and guide flat surfaces on the inspection jig that slidably contact to regulate the insertion position and direction, preventing swinging and ensuring accurate detection without affecting the waterproof properties or packing attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a guide mechanism is added to regulate insertion position and attitude of the inspection jig, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies partial action by providing guide flat surfaces only at the critical insertion interface between the inspection jig and connector housing, rather than guiding the entire insertion path. This selective guidance at the most critical point (insertion position regulation) achieves measurement precision improvement without the complexity of a complete guiding mechanism throughout the assembly.
Solution Approach 2:
The guide flat surfaces on both the inspection jig and connector housing serve as self-aligning features that automatically regulate insertion position and attitude through their geometric configuration. The complementary flat surfaces naturally guide the inspection jig into the correct position without requiring additional active control mechanisms, achieving self-service alignment.
2Adaptability or versatility
If the outer periphery is made curved for waterproof connector design, then adaptability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent applies local quality by maintaining the curved outer periphery for waterproof adaptability while introducing a localized flat guide surface at the specific insertion interface. This allows the majority of the connector to retain its curved, adaptable shape while providing a localized flat region that facilitates easy manufacturing and assembly of the inspection jig guidance system.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents false detection by ensuring proper alignment and smooth insertion of the detecting pin, facilitating accurate detection of the attachment state of the connecting terminal in waterproof connectors without compromising waterproof or packing attachment properties.
Implementation Method 1
a guide flat surface for slidably making surface contact with the reference flat surface in the case of inserting the detecting pin into the hole for inspection
Implementation Method 2
position and direction of insertion of the inspection jig into the connector housing are regulated by sliding contact between the reference flat surface and the guide flat surface

AI summary
There is provided a connector inspection system. A connector housing to be inspected includes reference flat surfaces formed by straight extending in an insertion direction of a connecting terminal in a top side outer peripheral region of a terminal receiving part so as not to overlap with a mounting range of a packing attachment surface, and an inspection jig includes guide flat surfaces for slidably making surface contact with the reference flat surfaces in the case of inserting a detecting pin into a hole for inspection of the connector housing, and a position and a direction of insertion of the inspection jig into the connector housing are regulated by sliding contact between the reference flat surfaces and the guide flat surfaces.
