Socket Connector Anti-Misinsertion Structure for RJ-45
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
RJ-11 and RJ-45 plug connectors, despite different specifications, often get misinserted due to similar appearances, leading to improper compression of conductive terminals in RJ-45 connectors, rendering them unusable.
Innovation Solution
A socket connector design featuring an anti-misinsertion component with a pivot and connecting arms, a guide piece, and a stop piece, combined with an insulating base and shielding casing, guides the RJ-45 plug connector while preventing the insertion of RJ-11 connectors through a clasp slot and elastic plates, ensuring proper alignment and protection of conductive terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If RJ-11 and RJ-45 plug connectors have similar appearances, then manufacturing and identification are simplified, but misinsertion occurs leading to terminal deformation
Solution Approach 1:
The patent applies asymmetry by designing the anti-misinsertion component with connecting arms that have different configurations for RJ-11 and RJ-45 connectors. The guide pieces and stop pieces are positioned asymmetrically relative to the pivot, creating distinct mechanical interfaces that prevent incorrect plug insertion while maintaining similar external appearances for manufacturing efficiency
Solution Approach 2:
The anti-misinsertion component serves as an intermediary mechanism between the socket and plug connectors. This component, with its pivot and connecting arms featuring guide pieces and stop pieces, acts as a mechanical mediator that physically blocks misinsertion attempts while allowing correct insertion, thereby protecting the conductive terminals without requiring fundamentally different connector designs
2Reliability
If anti-misinsertion components are added to prevent misconnection, then terminal protection is improved, but device complexity increases
Solution Approach 1:
The patent employs dynamics by designing the anti-misinsertion component with a pivot that allows the connecting arms to rotate. This dynamic structure enables the guide pieces and stop pieces to move into position during insertion, providing active misinsertion prevention through rotational motion rather than requiring complex static mechanical interlocks
Solution Approach 2:
The anti-misinsertion component is segmented into distinct functional elements: a pivot point, multiple connecting arms, guide pieces at the ends of connecting arms, and stop pieces positioned along the arms. This segmentation allows each element to perform its specific function independently while maintaining overall structural simplicity and ease of manufacturing

AI summary
An anti-misinsertion structure of a socket connector includes a pivot clasped to both sides of the top of an insulating base of the socket connector and two connecting arms extended horizontally from both sides of the pivot. Each connecting arm has a guide piece extended horizontally from an end of each connecting arm, a stop piece formed at the bottom of the connecting arm and proximate to the guide piece of the connecting arm, a downwardly tilted first guide bevel formed at the bottom of the guide piece, a position limit surface defined on a side of the guide piece and proximate to the stop piece, an upwardly tilted second guide bevel formed at the bottom of the stop piece, and a stop surface defined on a side of the stop piece and proximate to the guide piece and perpendicular to the position limit surface of the guide piece.
