Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shielding piece and additional conductive medium are used to connect the shielding medium to the conductive module, then the connection stability is improved, but the number of components increases and assembly efficiency decreases
Solution Approach 1:
The patent integrates the shielding medium directly with the conductive module by making the shielding layer itself conductive and forming an integrated connection structure. The shielding layer is electrically connected to the conductive module through direct contact or soldering without requiring separate shielding pieces or additional conductive media, thus merging multiple components into a unified structure that maintains connection stability while reducing component count
Solution Approach 2:
The patent removes the unnecessary shielding piece and additional conductive medium from the connection structure. By extracting these redundant components and establishing a direct connection between the shielding layer and conductive module, the design simplifies the overall structure while maintaining the essential function of electrical connection and shielding
2Reliability
If a shielding piece and additional conductive medium are used to connect the shielding medium to the conductive module, then the connection stability is improved, but assembly efficiency decreases
Solution Approach 1:
The patent combines the shielding function and electrical connection function into a single integrated structure where the shielding layer directly contacts the conductive module. This integration eliminates the need for separate assembly steps involving shielding pieces and additional conductive media, thereby improving assembly efficiency while maintaining connection stability through the unified design
3Reliability
If an additional conductive medium is used to transmit electrical signals from the shielding medium to the conductive module, then the connection is more stable, but transmission losses increase due to the longer transmission link
Solution Approach 1:
The patent removes the additional conductive medium from the signal transmission path. By establishing a direct electrical connection between the shielding layer and conductive module, the transmission link is shortened, which reduces transmission losses while maintaining connection stability through the direct contact interface

AI summary
Provided are a connection structure of a ground-free cable and a connection method of a ground-free cable. The connection structure of a ground-free cable includes a ground-free cable and a conductive module. The ground-free cable includes a conductor, an insulating layer, a shielding layer, and an outer wrapping layer which are sequentially wrapped. The ground-free cable has an insertion terminal mating with the conductive module. The insertion terminal is configured as follows: a part of the conductor is exposed outside the insulating layer and forms a conductor insertion portion, and a part of the shielding layer and a part of the insulating layer are both exposed outside the outer wrapping layer and form a shielding insertion portion. A receptacle is provided on the conductive module. The shielding insertion portion and the conductor insertion portion are both inserted into the receptacle and are electrically connected to the conductive module.
