Shield Connector With Inclined Pressing Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield connectors face challenges in consistently maintaining contact between braided conductors and shield shells, leading to variations in the contact state.
Innovation Solution
A shield connector design featuring a tubular-shaped ring with an inclined pressing surface that faces the shield shell axially, ensuring the braided conductor is pressed uniformly around the entire periphery, and a hooking part that folds into a hole in the shield shell to secure the ring in place, maintaining compressive stress on the conductor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixing member presses a braided wire against a shield shell, then the braided conductor is fixed to the shield shell, but variations in the contact state occur
Solution Approach 1:
The pressing surface is designed with an inclination angle of 45 degrees relative to the axial direction, creating a localized geometric feature that converts axial pressing force into radial compressive force. This local geometric modification ensures uniform radial pressure distribution across the entire periphery of the braided conductor, eliminating contact state variations while maintaining reliable electrical connection between the braided conductor and shield shell
Solution Approach 2:
The pressing surface inclination angle is specifically set to 45 degrees, changing the geometric parameter of the fixing member. This parameter change transforms the force transmission characteristics, ensuring that the pressing force is uniformly distributed in the radial direction across the entire circumference, thereby achieving consistent contact state and improving manufacturing precision
2Manufacturing precision
If the pressing surface is inclined at 45 degrees, then uniform radial pressing force is achieved, but the structural complexity increases
Solution Approach 1:
The pressing surface is designed with a specific inclination angle of 45 degrees relative to the axial direction. This parameter change creates a geometric transformation that converts axial pressing force into uniform radial compressive force, achieving uniform pressing force distribution without requiring complex multi-component structures. The single geometric parameter modification simplifies the overall device complexity while improving pressing force uniformity

AI summary
A shield connector (1) includes a braided conductor (2) through which an electric wire is inserted; a shield shell (3) formed in a tubular shape that has conductivity; and a ring (4) formed in a tubular shape in which a pressing surface (45a) that faces the shield shell in an axial direction (X) of the shield shell is formed on an inner surface side over an entire periphery. The pressing surface is inclined in a direction intersecting with the axial direction on a section in the axial direction. The ring is fixed to the shield shell while maintaining a state in which the pressing surface presses the braided conductor against the shield shell in the axial direction over the entire periphery.
