Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable connectors suffer from inconsistent shielding, leading to poor signal transmission performance, especially at high frequencies, and require an intermediate circuit board, increasing manufacturing costs.
Innovation Solution
The cable connector features an integrally formed shield mechanism with wave-shaped shield members and ground terminals connected by a crossbar, providing consistent shielding and eliminating the need for an intermediate circuit board by directly mounting signal conductors to the connector's terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable connectors use separate shielding components and intermediate circuit boards, then assembly flexibility is maintained, but signal transmission performance deteriorates due to inconsistent shielding
Solution Approach 1:
The patent merges the shielding mechanism with the terminal structure by integrating wave-shaped shield members directly onto the terminals. The shield members are formed as integral parts of the terminal assembly, eliminating the need for separate shielding components and intermediate circuit boards. This integration ensures consistent shielding across all signal transmission paths while reducing the overall device complexity.
Solution Approach 2:
The terminal structure serves multiple functions simultaneously: it provides electrical connection points, mechanical support, and consistent electromagnetic shielding. The wave-shaped shield members are designed to work with the terminal geometry, creating a multi-functional component that eliminates the need for dedicated shielding structures and intermediate circuit boards.
2Ease of manufacture
If conventional cable connectors use intermediate circuit boards, then electrical connections are established, but manufacturing costs increase
Solution Approach 1:
The patent extracts and eliminates the intermediate circuit board from the connector structure. By integrating the shielding mechanism directly into the terminal assembly, the design removes the unnecessary intermediate component, thereby reducing manufacturing costs while maintaining the essential electrical connection function.
Solution Approach 2:
The terminal and shielding mechanism are merged into a single integrated structure. The wave-shaped shield members are formed as integral parts of the terminal assembly, eliminating the need for separate circuit boards and reducing the number of assembly steps, which directly lowers manufacturing costs.
3Ease of manufacture
If cable connectors eliminate intermediate circuit boards, then manufacturing costs are reduced, but mechanical and electrical connections must be simplified
Solution Approach 1:
The terminal and shielding mechanism are merged into a single integrated structure. The wave-shaped shield members are formed as integral parts of the terminal assembly, eliminating the need for separate circuit boards and reducing the number of assembly steps, which directly lowers manufacturing costs while maintaining connection reliability.
Solution Approach 2:
The wave-shaped shield members are strategically positioned at specific locations where electromagnetic interference is most likely to occur. This localized shielding approach ensures that critical connection points are protected while maintaining overall connection reliability, without requiring complex intermediate structures.

AI summary
A cable assembly with a shielded termination portion where signal conductors of a plurality of cables are directly mounted to tail portions of signal terminals of a cable connector. Shielding in the termination portion may be provided by interaction of a wave-shaped shield, tail portions of ground terminals between tail portions of the signal terminals, a cross bar connecting the ground terminals and an exposed portion of a cable shield. The wave-shaped shield may be mechanically connected to at least the tail portions of the ground terminals and may be configured to press the cable shields into the crossbar. Such a configuration improves signal transmission performance by providing a consistent shielding at the connection areas where the cables are mounted to the tail portions of the conductive terminals and at the same time eliminates the need of an intermediate circuit board and therefore reduces manufacturing costs.
