Plug-In Connector Frame Assembly With Snap Lock and Spring Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies require complex assembly processes due to the need for screw connections between the holder frame and the housing part, which complicates the mechanical and electrical connection.
Innovation Solution
The assembly features a holder frame with a recording room for contact applications and a housing part with a recording opening, utilizing a spring element and a locking element to establish a secure, reliable connection without screw connections. The spring element provides elastic behavior for electrical contact, while the locking element ensures mechanical locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw connection is used to connect the holding frame to the housing part, then the mechanical strength and reliability of the connection is improved, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The invention extracts and eliminates the screw connection from the assembly process. Instead of using traditional screw fastening, the patent employs a snap-in mechanism where the holding frame is directly inserted into the housing part and locked into position, removing the intermediate screw fastening step entirely while maintaining connection reliability
Solution Approach 2:
The holding frame incorporates self-locking features that automatically engage with the housing part upon insertion. The frame's geometry and material properties enable it to self-fasten without external fastening elements, allowing the assembly to service itself during the connection process
2Strength
If a screw connection is used to connect the holding frame to the housing part, then the mechanical strength of the connection is improved, but the assembly time and productivity are reduced
Solution Approach 1:
The holding frame is pre-designed with integrated locking features and geometric shapes that enable direct insertion and automatic locking into the housing part. This preliminary design eliminates the need for sequential screw fastening operations, allowing the connection to be established in a single insertion motion, thereby significantly improving assembly productivity while maintaining connection strength
3Reliability
If a spring element is used to provide electrical contact, then the electrical connection reliability is improved, but the device complexity increases
Solution Approach 1:
The holding frame serves multiple functions simultaneously: it provides mechanical support, structural alignment, and electrical contact through the integrated spring element. This multi-functionality eliminates the need for separate electrical contact components, maintaining structural simplicity while ensuring reliable electrical connection
Solution Approach 2:
The spring element is merged with the holding frame structure, combining the mechanical support function and electrical contact function into a single integrated component. This merging reduces the total number of parts and simplifies the overall connector structure while ensuring reliable electrical contact through the spring's elastic properties
