Shared Cable-to-Board Connector Housing for Cost and Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector systems for circuit boards and cables have increased manufacturing costs due to the need for individually designed components, particularly because of differences in the shape of outer conductors made of metal plate materials and those formed by casting or die casting, leading to separate designs for board-side and cable-side connectors.
Innovation Solution
A connector system where a cable-side connector with a metal outer conductor and synthetic resin housing can connect to multiple types of board-side connectors with metal outer conductors and resin housings, allowing sharing of components to reduce manufacturing costs, including the use of bent metal plate materials for one type and casting for another to improve shielding performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the outer conductor is made of bent metal plate material, then manufacturing cost is reduced, but gaps are formed in the outer conductor leading to increased noise susceptibility
Solution Approach 1:
The patent applies this principle by using bent metal plate material for the outer conductor of the board-side connector, which is a cost-effective manufacturing approach. The metal plate is bent into shape to form the outer conductor, providing a low-cost solution while maintaining functional performance.
Solution Approach 2:
The patent changes the physical parameters of the connector design to accommodate different outer conductor types. The cable-side connector is designed with flexible connection interfaces and positioning structures that can adapt to both bent metal plate outer conductors and cast outer conductors, allowing the same cable-side connector to work with different board-side connector types.
2Object-affected harmful factors
If the outer conductor is formed by casting or die casting, then no gaps are formed improving noise resistance, but manufacturing cost increases
Solution Approach 1:
The patent applies this principle by using bent metal plate material for the outer conductor of the board-side connector, which is a cost-effective manufacturing approach. The metal plate is bent into shape to form the outer conductor, providing a low-cost solution while maintaining functional performance.
3Reliability
If board-side connectors and cable-side connectors are individually designed for different outer conductor shapes, then connection performance is optimized, but manufacturing cost increases for both connectors
Solution Approach 1:
The patent applies this principle by designing the cable-side connector to be universal and compatible with multiple types of board-side connectors. The cable-side connector includes a housing and positioning structures that can accommodate both bent metal plate outer conductors and cast outer conductors, allowing a single cable-side connector design to work with different board-side connector types and reduce overall manufacturing costs.
Solution Approach 2:
The patent segments the connector system into two independent parts: the board-side connector with its specific outer conductor type (bent metal plate or cast), and the universal cable-side connector. This segmentation allows each part to be optimized independently while maintaining compatibility through standardized connection interfaces and positioning structures.
