Plug Connector Latching Frame for Screwless EV Socket Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connector parts for electric vehicle charging sockets face difficulties in assembly due to the need for multiple screw connections and adaptations for different vehicle housing designs, complicating the connection process and increasing assembly time.
Innovation Solution
A modular plug connector part design featuring a frame part that latches onto the connector part to secure the cover element and housing part, eliminating the need for screw connections and allowing for standardized connector parts to be used across various vehicle designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw connections are used to connect the connector part to the housing part and the cover element to the connector part, then the connection is secure and reliable, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The patent replaces the screw connection system with a snap-fit latching system. The frame part includes latching elements that engage with corresponding recesses in the connector part, eliminating the need for screws and simplifying the assembly process while maintaining secure connections.
Solution Approach 2:
The patent combines multiple functions into the frame part: it serves as both the mounting structure for the cover element and the latching mechanism for securing the connector part to the housing part. This integration reduces the number of separate components and assembly steps required.
2Adaptability or versatility
If the connector part is adapted for different housing designs in different vehicles, then it can be fastened to various housing parts, but the connector part loses standardization and becomes more difficult to manufacture
Solution Approach 1:
The patent divides the plug connector part into separate functional modules: the standardized connector part with contact elements and the vehicle-specific housing part. The frame part acts as an adapter that connects these modules, allowing the standardized connector part to be used across different vehicle models while accommodating various housing designs.
Solution Approach 2:
The frame part is designed as a universal component that can adapt to different housing configurations. It includes standardized latching interfaces that work with various housing parts across different vehicle models, maintaining connector part standardization while providing housing compatibility.
