High-Speed Connector Cap Structure for 60 GHz Crosstalk Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-speed transmission connectors suffer from noise and deteriorated transmission characteristics due to the exposure of the receiving tip end portion of the contacts, which causes signal reflection and interference.
Innovation Solution
The connector design includes a housing with upper and lower plate portions and contact rows, where each contact has a receiving portion with a curved shape and a receiving tip end portion that is accommodated within a cap's accommodation space, preventing direct contact with the header and reducing signal interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the receiving tip end portion is left exposed without protective material, then manufacturing cost is reduced, but signal reflection and noise occur causing deteriorated transmission characteristics
Solution Approach 1:
The patent introduces a protective material (accommodation space with cap structure) as an intermediary element between the receiving tip end portion and the external environment. This mediator prevents direct exposure of the tip end, thereby eliminating signal reflection and noise while maintaining manufacturing feasibility through simple structural additions.
Solution Approach 2:
The patent applies preliminary protective measures by providing the accommodation space and cap structure before signal transmission occurs. This preliminary anti-action prevents the harmful effect of signal reflection at the exposed tip end portion, ensuring good transmission characteristics from the outset without requiring complex post-processing.
2Device complexity
If the receiving tip end portion is exposed, then the structure is simpler, but high frequency signals flow back causing noise
Solution Approach 1:
The patent extracts the harmful receiving tip end portion from the active signal path by enclosing it within the accommodation space of the cap structure. This separation removes the source of noise generation while maintaining the necessary electrical connection functionality through the curved portion.
Solution Approach 2:
The patent applies different structural qualities to different portions of the contact: the receiving tip end portion is enclosed and protected within the accommodation space, while the curved portion maintains its arch shape for electrical connection. This local differentiation eliminates noise at the tip end while preserving signal transmission capability.

AI summary
A high-speed transmission connector includes a connector housing with a slot, upper and lower plate portions facing each other across the slot, first and second contact rows arranged face to face with each other within the connector housing, first and second caps supported in a hole of the upper plate portion and the lower plate portion, respectively. Each contact of the first and second contact row includes a receiving portion to receive a header of an external communication device. The receiving portion includes a receiving tip end portion facing an insertion side of the header and a curved portion extending from a rear end of the receiving tip end portion and bent in an arch shape.
