Engineering Contradiction Analysis
1Reliability
If a cable connection structure with conductive tubes and insulating tubes is implemented, then the reliability and interference resistance of cable connections is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent implements a nested cable connection structure where the insulating tube is inserted over the cable end first, then the conductive tube is mounted over the insulating tube. The signal wire and ground wire are sequentially inserted through the insulating tube into the conductive tube, creating a nested arrangement of tubes and wires that provides both insulation and electrical connection in a compact configuration.
Solution Approach 2:
The cable connection structure is divided into distinct functional segments: an insulating tube for electrical isolation and cable protection, a conductive tube for electrical connection to the printed circuit board, and separate signal and ground wires. This segmentation allows each component to perform its specific function independently while working together as an integrated connection system.
2Object-affected harmful factors
If multiple tubes (insulating tube and conductive tube) are mounted on cable ends, then the protection against interference and electrical connection stability is improved, but the manufacturing process complexity increases
Solution Approach 1:
The insulating tube is mounted on the cable end before the conductive tube is installed. This preliminary action of insulating the cable end first prevents interference and provides a stable base for subsequent conductive tube mounting, ensuring that the electrical connection is established on top of a already-protected and isolated structure.
Solution Approach 2:
The conductive tube is mounted over the insulating tube, creating a nested configuration where the smaller insulating tube is contained within the larger conductive tube. This nesting approach allows both tubes to be integrated in a single assembly process, reducing the number of separate mounting operations required.
