Shield Connector Protection Walls and Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield connectors with exposed resilient contact pieces are prone to damage and deformation during handling and assembly, as they can be caught by surrounding objects or subjected to foreign matter interference.
Innovation Solution
The shield connector design incorporates a housing with a receptacle, a mounting flange, and protection walls that accommodate the resilient contact pieces, preventing external interference and ensuring stable contact with the mounting member, while the arcuate contact portions and elongated projections maintain contact pressure and prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the resilient contact pieces are exposed to the outside for easy access and assembly, then the ease of operation is improved, but the reliability deteriorates due to damage and deformation during handling and assembly
Solution Approach 1:
The resilient contact pieces are nested within the housing structure, specifically within recesses formed in the mounting flange. This nesting arrangement protects the contact pieces from external damage during handling and assembly while keeping them accessible for their grounding function, thereby resolving the contradiction between ease of operation and reliability.
2Ease of manufacture
If the resilient contact pieces are exposed for direct contact with mounting surfaces, then the ease of manufacture is improved, but the object-affected harmful factors increase due to foreign matter entry and deformation
Solution Approach 1:
The resilient contact pieces are nested within recesses in the mounting flange, creating a protected environment that prevents foreign matter from reaching and interfering with the contact pieces during assembly and operation, while maintaining manufacturing simplicity.
Solution Approach 2:
The housing structure acts as an intermediary between the resilient contact pieces and the external environment, mediating protection against foreign matter while allowing the contact pieces to perform their grounding function effectively.
3Adaptability or versatility
If the resilient contact pieces are left exposed for flexibility and contact capability, then the adaptability is improved, but the strength deteriorates due to susceptibility to damage and deformation
Solution Approach 1:
The resilient contact pieces maintain their flexibility and adaptability for grounding contact while being nested within the housing structure, which provides protective support that enhances their strength and durability against damage and deformation during handling and operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively protects the resilient contact pieces from damage and deformation, ensuring reliable grounding and secure assembly by enclosing the leading ends within the mounting flange and using protection walls to prevent foreign matter entry, while maintaining stable contact pressure.
Implementation Method 1
one or more resilient contact pieces (120) formed on a part of the shell main body (110)... having leading end portions (121) to be at least partly accommodated in accommodating portions (67) formed in a rear surface (61B) of the mounting flange (61)
