Connector Guiding Pillars and Elastic Buckles for Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical plug and receptacle connectors lack a guiding mechanism, making alignment difficult, require an independent ring-shaped buckle for securing the connection, which complicates the structure and increases costs, and are ineffective in preventing electromagnetic interference (EMI) and radio frequency interference (RFI).
Innovation Solution
The design incorporates an electrical plug connector with an insulated housing, elastic buckle elements, and a metallic shell, featuring guiding pillars for alignment and elastic buckle elements for secure engagement, while the receptacle connector includes a metallic shell with grounding sheets to shield against EMI and RFI.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If no guiding device is provided between the plug connector and receptacle connector, then the structure is simpler, but the user has to align them carefully which increases operation difficulty
Solution Approach 1:
The patent applies preliminary action by providing guiding pillars on the plug connector and corresponding guiding slots on the receptacle connector before the main connection operation. These guiding features are pre-formed structures that automatically align the connectors during insertion, eliminating the need for careful manual alignment by the user while maintaining simple overall structure.
2Reliability
If an independent ring-shaped buckle is used to secure the connection, then the connection is more secure, but the whole structure becomes complicated and cost increases
Solution Approach 1:
The patent merges the buckle function with the receptacle connector housing by integrating the buckle element directly into the receptacle connector structure. The buckle is formed as part of the receptacle housing rather than being an independent component, which maintains secure connection reliability while simplifying the overall structure and reducing part count and manufacturing cost.
3Ease of manufacture
If the conventional receptacle connector structure is used, then manufacturing is simpler, but it is not effective in preventing electromagnetic interference and radio frequency interference
Solution Approach 1:
The patent applies composite materials by combining metallic materials with electromagnetic shielding properties with the connector structure. The receptacle connector incorporates metallic shielding elements and grounding features that provide EMI and RFI protection while maintaining manufacturability through integrated forming processes.

AI summary
An electrical plug connector has an insulated housing, two elastic buckle elements, multiple plug terminals, and a plug metallic shell. The insulated housing has a terminal portion and two connecting portions. The two elastic buckle elements are respectively mounted in receiving grooves of the two connecting portions of the insulated housing. Multiple plug terminals are arranged on the terminal portion of the insulated housing. An electrical receptacle connector is detachably connected with the electrical plug connector. The electrical receptacle connector has a receptacle insulated housing and multiple receptacle terminals. The receptacle insulated housing has an inserting portion and two receptacle connecting portions. The multiple receptacle terminals are mounted in a mounting slot of the receptacle insulated housing. When the electrical plug connector is connected with the electrical receptacle connector, the multiple plug terminals may contact the multiple receptacle terminals and are conducted.
