Connector Alignment via Guide-Positional Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors lack guidance and positional limiting features, leading to misalignment issues during plug insertion and increased dimensions due to improper alignment.
Innovation Solution
The electrical connection device incorporates a receptacle connector with front and rear guide-positional limiting portions and latching members, along with a plug connector featuring a U-shaped latching member and recessed grooves, ensuring accurate alignment and reduced dimensions through elastic deformation and positional guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interlocking portions are added to existing electrical connectors, then connection stability is improved, but misalignment during insertion cannot be prevented
Solution Approach 1:
The patent applies preliminary action by incorporating guide-positional limiting portions that perform alignment guidance before the interlocking portions engage. The guide groove and guide protrusion structure guides the plug connector into correct position during insertion, preventing misalignment before the latching mechanism engages, thus resolving the contradiction between connection stability and alignment accuracy
2Manufacturing precision
If guide-positional limiting portions are added to improve alignment, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent merges the guide-positional limiting portions with the existing interlocking structure. The guide groove is formed within the receptacle body that already contains interlocking portions, and the guide protrusion is integrated with the plug connector's latching member. This integration allows alignment guidance without adding separate independent components, thus improving manufacturing precision while minimizing device complexity
3Reliability
If traditional interlocking structures are used, then connection stability is achieved, but overall device dimension increases
Solution Approach 1:
The patent applies the nested doll principle by placing the guide groove inside the receptacle body and the guide protrusion inside the latching member structure. The guide-positional limiting portions are nested within the existing connector boundaries rather than adding external protrusions, allowing alignment guidance and stable connection while maintaining compact overall dimensions

AI summary
An electrical connection device comprises: a receptacle connector and a plug connector. The receptacle connector comprises a receptacle body, a front guide-positional limiting portion, a rear guide-positional limiting portion and a first latching member. The plug connector removably mates with the receptacle connector, and comprises a plug body and a second latching member, when the plug connector mates with the receptacle connector, the second latching member of the plug connector is latched to the first latching member of the receptacle connector and limited by the front guide-positional limiting portion, and the rear guide-positional limiting portion of the receptacle connector engages with a recessed portion of the plug connector, so that two side walls of the plug connector are respectively exposed to two side openings of the receptacle connector and generally flush with two side walls of the receptacle connector.
