Single-Twisted-Pair Connector Layout for Ethernet Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for Ethernet cables typically require four twisted pairs of conductors, which is not efficient for applications that only need to transmit data and/or power using a single twisted pair of conductors.
Innovation Solution
A family of connectors specifically designed for a single twisted pair of conductors, including a free connector, a fixed connector, and an adapter, which can be modified to accommodate various patch cord and mounting configurations, and adopt configurations similar to LC fiber optic connectors but with adjusted footprints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard Ethernet connector designed for four twisted pairs is used, then compatibility with existing Ethernet infrastructure is maintained, but connector size and complexity increase unnecessarily for single-pair applications
Solution Approach 1:
The patent divides the traditional four-pair Ethernet connector into a dedicated single-pair connector configuration. The connector housing, contacts, and internal structure are segmented and redesigned to accommodate only one twisted pair, eliminating unnecessary components while maintaining electrical connectivity functions.
Solution Approach 2:
The invention extracts only the essential elements needed for single-pair transmission from the four-pair connector design. This includes removing three pairs of contacts and associated structural elements, retaining only the necessary components for transmitting data and/or power over a single twisted pair.
2Quantity of substance
If a connector designed for four twisted pairs is used, then sufficient conductors are available for differential signaling, but the connector does not efficiently support applications requiring only a single twisted pair
Solution Approach 1:
The patent applies partial action by providing exactly the number of conductors needed (two conductors for one twisted pair) rather than the full four pairs. This eliminates wasted capacity while ensuring sufficient conductors are available for the required data and/or power transmission functions.
3Device complexity
If a compact single-pair connector is designed, then connector size and complexity are reduced, but compatibility with existing Ethernet standards and infrastructure may be compromised
Solution Approach 1:
The patent designs the single-pair connector to be universally compatible with existing Ethernet infrastructure through standardized interfaces and protocols. The connector maintains compatibility with Ethernet standards while being optimized for single-pair applications, allowing it to function in various network configurations including data transmission and power delivery.

AI summary
An aspect of the present disclosure is directed to a connector. The connector is suited to connectorizing exactly two conductors. The connector includes a forward connector body, a rear connector body, a metal frame and exactly two electrical contacts. The rear connector body interfaces with the forward connector body. Further, the metal frame, which includes a shielding interface, surrounds at least a portion of both the forward and rear connector bodies. The electrical contacts extend from the rear connector body into the forward connector body. A first of the electrical contacts is electrically coupled to a first conductor of a shielded cable and the second of the electrical contacts is electrically coupled to a second conductor of the shielded cable. The shield interface of the metal frame is electrically coupled to the shield of the shielded cable.
