Connector Assembly Airtightness via Conductive Metal Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connector assemblies for substrate-to-substrate connections lack sufficient airtightness, allowing dust to invade the connector area due to inadequate contact between the protective member's surfaces and the substrates.
Innovation Solution
A connector assembly featuring a protective member with a conductive metal fitting and an insulating body, integrated with a reinforcing metal fitting, and an interposing member to ensure secure attachment and maintain high airtightness by filling the gap between the protective member and the substrates, using a combination of potting agents and adhesive for sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the protective member is made with simple contact surfaces, then the device complexity is reduced, but the airtightness between the protective member and substrate deteriorates
Solution Approach 1:
The protective member combines a resin body with a metal fitting integrated into it. The metal fitting provides enhanced surface contact and sealing capability with the substrate, while the resin body provides structural support and protection. This composite structure achieves high airtightness without requiring complex separate sealing components.
2Ease of manufacture
If the protective member only contacts the substrate at attachment surfaces, then the ease of manufacture is improved, but the airtightness and dust prevention capability deteriorates
Solution Approach 1:
The metal fitting is strategically positioned at the contact interface between the protective member and substrate, providing localized enhanced sealing properties where airtightness is most critical. The rest of the protective member maintains its simple resin construction for ease of manufacture, achieving dust prevention without overall structural complexity.

AI summary
A connector assembly can be attached to a surface of a substrate and has high airtightness to improve reliability. The connector assembly includes: a connector including a connector body and a terminal attached to the body; and a protective member including a wall extending in a longitudinal direction or a width direction of the body and an accommodation unit in which at least a part of four sides of a periphery is defined by the wall, the protective member being attached to the surface of the substrate with the connector accommodated in the accommodation unit. The protective member includes a protective member body made of an insulating material and a protective metal fitting made of a conductive metal integrally formed with the protective member body, and the protective member is placed on the surface of the substrate while coupled to the connector with the connector accommodated in the accommodation unit.
