High Voltage Shielded Connector Moisture Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High voltage shielded connectors with braided nets are prone to corrosion and separation due to exposure to moisture and external forces, as the connection portion between the metal shielding member and the braided net is not adequately sealed or reinforced.
Innovation Solution
A high voltage shielded connector design that includes a braided net cover and an outer binding member with locking steps and sealing lips to seal and reinforce the connection between the metal shielding member and the braided net, preventing moisture ingress and enhancing the binding strength against external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the connection portion between the metal shielding member and the braided net is exposed to the outside, then the structure is simple and easy to manufacture, but the connection portion is prone to corrosion due to moisture contact
Solution Approach 1:
The patent employs a braided net cover made of flexible material that envelops the connection portion between the metal shielding member and the braided net. This flexible shell structure provides moisture protection while accommodating the cylindrical geometry of the connection area, effectively preventing corrosion without complicating the manufacturing process.
Solution Approach 2:
The braided net cover acts as an intermediary element between the metal shielding member and the external environment. It mediates the protection function by creating a barrier against moisture while maintaining the electrical connectivity and mechanical binding of the underlying components.
2Device complexity
If the connection portion between the metal shielding member and the braided net is exposed to the outside, then the structure is simple, but the braided net may be separated from the metal shielding member when external force acts on it
Solution Approach 1:
The braided net cover serves as a flexible protective shell that not only shields the connection portion from moisture but also provides mechanical reinforcement. When external forces act on the assembly, the cover distributes and absorbs these forces, preventing separation between the braided net and the metal shielding member.
Solution Approach 2:
The braided net cover is installed beforehand to cushion and protect the vulnerable connection portion from external forces. This preemptive protective measure ensures that when external impacts or forces are applied, the connection portion is already shielded, preventing separation or damage.
3Ease of manufacture
If a binding ring is used to bind the braided net to the metal shielding member, then the binding is simple to implement, but the connection portion remains exposed and vulnerable to corrosion and separation
Solution Approach 1:
The braided net cover is a flexible shell structure that envelops the connection portion secured by the binding ring. It maintains the simplicity of the binding ring installation while adding a protective layer that prevents both corrosion from moisture and separation from external forces, thereby enhancing reliability without complicating the manufacturing process.
Solution Approach 2:
The invention merges two functions into a single integrated solution: the binding ring provides mechanical attachment while the braided net cover simultaneously provides moisture protection and additional mechanical reinforcement. This combination achieves both ease of manufacture and high reliability by layering protective functions.
