Connector Stabilizer Guides Terminal Insertion Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current connectors with recessed spaces behind the mating terminal connecting portion hinder smooth current flow and are challenging to apply for high-frequency electrical reliability.
Innovation Solution
A connector design featuring a stabilizer on the terminal fitting that guides and restricts insertion posture, combined with a retainer and deflectable locking lance, eliminating the need for a lance hole in the mating connecting portion, ensuring current flow and enhancing electrical reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate parts are provided for guiding insertion and restricting erroneous insertion, then the terminal fitting can be properly positioned, but the device complexity increases
Solution Approach 1:
The stabilizer on the terminal fitting serves multiple functions simultaneously: it guides the terminal fitting into the cavity during insertion, restricts erroneous insertion postures, and provides structural support. This multi-functional design eliminates the need for separate guiding and restriction parts, reducing overall device complexity.
Solution Approach 2:
The patent merges the functions of insertion guidance and erroneous insertion restriction into a single integrated stabilizer structure. Rather than having separate guiding features and restriction features, the stabilizer combines both functions in one component, simplifying the terminal fitting structure.

AI summary
A connector (C) includes a housing (60), a terminal fitting (10) and a retainer (80). The housing (60) includes a cavity (64) extending in a front-rear direction and a retainer insertion hole (72) intersecting and communicating with the cavity and open in an outer surface. The terminal fitting (10) is inserted into the cavity (64) from behind, and a stabilizer configured to guide an inserting operation into the cavity (64) and restrict the inserting operation in an erroneous posture projects on an outer side. The retainer (80) is inserted into the retainer insertion hole (72) and include a retaining portion (85) configured to face the stabilizer from behind.
