Electrical Connector Fitting Structure for Stable Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When inspecting electrical connectors using an inspection device, there is a risk of unstable contact due to misfitting, and the engagement process can lead to wear or deformation of the connector engagement portions, affecting the extraction force and resulting in variable inspection outcomes.
Innovation Solution
The electrical connector design features a fitting portion with a first engagement wall portion and a separate engagement wall portion for inspection, allowing for stable inspection without impacting the extraction force of the connector engagement portion by using a distinct configuration for the inspection device's engagement, including a convex and concave structure for reliable fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the engagement portion is used for both connector fitting and inspection device fitting, then the device complexity is reduced, but the reliability of inspection and connector extraction deteriorates due to wear and deformation
Solution Approach 1:
The patent divides the engagement wall into two separate engagement portions: a first engagement portion for connector fitting and a second engagement portion for inspection device fitting. This segmentation prevents wear and deformation from affecting both functions simultaneously, thereby improving inspection reliability while maintaining reasonable structural complexity
2Device complexity
If the engagement portion is used for both connector fitting and inspection device fitting, then the device complexity is reduced, but the extraction force of the connector engagement portion deteriorates
Solution Approach 1:
By separating the engagement portions, the first engagement portion maintains its original extraction force characteristics without being compromised by inspection operations. The second engagement portion handles inspection device fitting independently, preventing force degradation
3Productivity
If the electrical connector and inspection device are fitted together, then inspection can be performed, but the probe cannot stably contact the internal terminal due to misfitting
Solution Approach 1:
The separate second engagement portion provides a dedicated interface for inspection device fitting, ensuring proper alignment and stable contact between the probe and internal terminal during inspection operations
Solution Approach 2:
The second engagement portion acts as an intermediary interface specifically for inspection purposes, mediating between the inspection device and the electrical connector to ensure stable fitting and accurate measurement

AI summary
An electrical connector is capable of performing stable inspection without affecting an extraction force of a connector engagement portion. The electrical connector includes a housing having an electrical insulation property, an internal terminal held by the housing, and an external terminal held by the housing, with the external terminal to be electrically connected to a ground. The external terminal includes a fitting portion having a first engagement wall portion at one side and having a second engagement wall portion at the other side in a plan view from a connector insertion/extraction direction. A first engagement portion is formed at the first engagement wall portion, and a second engagement portion is formed at the second engagement wall portion.
