Shield Cover for Braided Wire with Inclined Securing Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting braided wire shields to shield members are prone to tearing and deformation, leading to compromised shielding performance and increased labor and apparatus costs due to the need for additional clamp members.
Innovation Solution
A shield cover with a securing section featuring an inclined plane and protuberances that securely fixes the braided wire to the shield member through a single pressing operation, eliminating the need for additional clamp members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamp members are used to fix the braided wire to the shield member, then the braided wire can be secured, but the braided wire is easily torn and plastically deformed due to fastening force
Solution Approach 1:
A buffer member is introduced as an intermediary between the clamp member and the braided wire. The buffer member has a pressing section that contacts the braided wire and a clamped section that is clamped by the clamp member. This intermediary structure distributes the fastening force more evenly, preventing direct concentration of force on the braided wire that causes tearing and plastic deformation, while still achieving reliable fixation.
Solution Approach 2:
The clamp member is designed with a specific clamping force parameter that is optimized to be sufficient for fixation but not excessive to cause damage. The buffer member further modulates this force parameter by providing a larger contact area with the braided wire, effectively reducing the pressure (force per unit area) on the wire while maintaining the total clamping force needed for reliable connection.
2Reliability
If clamp members are coupled to the shield member, then the braided wire can be fixed, but labor costs and apparatus costs increase
Solution Approach 1:
The buffer member and clamp member are designed as an integrated assembly where the buffer member is positioned between the clamp member and the braided wire in a single structural unit. This merged design eliminates the need for separate operations to install and adjust individual clamp members, reducing both labor costs and the complexity of apparatus required for assembly.
3Reliability
If clamp members are coupled to the shield member, then the braided wire can be fixed, but assembly time increases and productivity decreases
Solution Approach 1:
The buffer member is pre-positioned between the clamp member and the braided wire during the manufacturing process. This preliminary action ensures that when the clamp member is applied, the buffer member is already in the correct position to distribute the clamping force evenly, eliminating the need for additional adjustment steps during assembly and thereby increasing assembly speed and productivity.

AI summary
A shield cover for a braided wire shield that is capable of securely fixing a braided wire to a shield member through a single pressing operation. The shield cover having a mating end, an inner casing, an outer cover housing. and a securing section. The inner casing positioned at an end opposite the mating end and having a shield receiving passageway. The outer cover housing positioned at the mating end of the shield cover and forming a connector receiving passageway being wider than the shield receiving passageway. The securing section extends from the inner casing toward the mating end and positioned apart from the outer cover housing.
