Shielded Connector Housing for Transmission Characteristic Tuning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector designs require changes in the housing shape when mating members are changed, leading to increased manufacturing costs due to the need for adjusting transmission characteristics.
Innovation Solution
A connector with a housing featuring accommodating portions and mounting portions at different distances, allowing the shield member to be mounted in various positions to adjust transmission characteristics without requiring new housing designs, using grooves for easy mounting and shared shield plates to reduce component variety and simplify the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the housing shape is changed to adjust transmission characteristics for different mating members, then the transmission characteristics can be matched, but the manufacturing cost increases
Solution Approach 1:
The connector is divided into modular components: a standard housing and separate shield members that can be independently configured. The shield members are segmented into first and second shield members that can be selectively combined to achieve different transmission characteristics without changing the housing itself.
Solution Approach 2:
The connector structure is made dynamically adaptable through the selective combination of different shield members. The first and second shield members can be configured in various arrangements (both present, only first, only second) to dynamically adjust transmission characteristics based on the mating member being connected.
2Adaptability or versatility
If multiple types of housings are provided to match different mating members, then transmission characteristics can be adjusted, but the device complexity increases
Solution Approach 1:
A single universal housing design is used that can accommodate different mating members through the selective configuration of shield members. The housing itself remains unchanged while the shield members provide the adaptability needed for different connection scenarios.
Solution Approach 2:
Instead of changing the housing structure, the transmission characteristics are adjusted by changing the parameters of the shield members (their presence, absence, position, or configuration). This allows versatility to be achieved through parameter variation rather than structural redesign.
Applied Scientific Principles

AI summary
It is aimed to provide a connector capable of adjusting transmission characteristics while suppressing a manufacturing cost increase. A connector is provided with a housing including an accommodating portion and mounting portions, a terminal fitting to be accommodated into the accommodating portion, and a shield member to be mounted into the mounting portions for shielding electromagnetic waves. The mounting portions are provided at a plurality of positions at different distances from the accommodating portion. For example, the mounting portion is in the form of a groove and one end is open in one surface of the housing.
