Electrical Connector Pickup Cap With Elastic Hook Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connector assemblies require excessive force for assembly and disassembly, which can damage hooks and lead to unstable electrical connections between chip modules and printed circuit boards due to rigid engagement mechanisms.
Innovation Solution
The electrical connector assembly employs elastic hooks and securing recesses in the housing, allowing for a secure and stable engagement of the pick up cap with the connector using a vacuum suction mechanism, reducing the required assembly force and ensuring a reliable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid interferential engagement hooks are used to secure the pick up cap to the electrical connector, then the connection strength is improved, but the assembly and disassembly force required increases significantly, leading to hook damage and unstable electrical connections
Solution Approach 1:
The patent changes the engagement mechanism from rigid interferential hooks to elastic hooks that can deform elastically. This parameter change in the mechanical properties of the engagement structure allows the hooks to flex during assembly and disassembly, reducing the force required while maintaining secure connection during operation.
Solution Approach 2:
The patent introduces dynamic characteristics to the engagement system through elastic hooks that can deform and recover. Unlike static rigid hooks, these elastic hooks adapt to assembly forces by deforming, then return to their original shape to maintain secure engagement, enabling easier assembly and disassembly without compromising connection strength.
2Reliability
If greater assembly force is applied to secure the pick up cap, then the engagement reliability is improved, but the risk of destroying hooks and causing open electrical connections increases
Solution Approach 1:
The patent incorporates elastic deformation capability as a cushioning mechanism before damage occurs. The elastic hooks can absorb assembly forces through controlled deformation, preventing excessive forces from reaching critical thresholds that would cause hook destruction or electrical connection failure.
Solution Approach 2:
By changing from rigid to elastic material properties of the hooks, the system can tolerate higher assembly forces without damage. The elastic properties allow the hooks to deform within safe limits during assembly, then maintain reliable engagement without the risk of catastrophic failure that plagues rigid hook designs.
3Device complexity
If rigid engagement structures are used, then the structural simplicity is maintained, but the stability of electrical connection during assembly decreases due to excessive shaking
Solution Approach 1:
The patent introduces dynamic elastic deformation capability to the engagement structure, which paradoxically improves stability during assembly. The elastic hooks can absorb assembly-induced vibrations and movements through controlled deformation, preventing the excessive shaking that causes connection instability in rigid structures, while adding minimal complexity to the overall design.
