Solution Overview
Problem
Existing technologies face challenges in efficiently coupling pairs of connectors to a single twisted pair of conductors, which limits the compact and effective transfer of data and power in communications networks.
Innovation Solution
A coupler design that includes a metal housing with a pair of pin contacts, each with a square or rectangular cross-section and tapered faces, which are offset and cross within the coupler to maintain electrical polarity when coupling two free connectors each with two electrical tuning fork contacts.

Engineering Contradiction Analysis
1Volume of moving object
If a single twisted pair of conductors is used for data and power transmission, then cable compactness and simplicity are improved, but electrical polarity maintenance and signal integrity become more difficult
Solution Approach 1:
The connector is divided into separate contact elements (tuning fork contacts in the connector, pin contacts in the coupler) that can be independently configured to maintain polarity. Each contact is a discrete component that can be precisely positioned and shaped to ensure proper signal transmission while maintaining cable compactness.
Solution Approach 2:
The tuning fork contacts and pin contacts are designed with asymmetric geometries where each contact has a specific orientation. The tapered faces and offset positioning create an asymmetric connection that inherently maintains electrical polarity, ensuring that signal integrity is preserved even in a compact single-pair configuration.
2Reliability
If traditional Ethernet connectors with four pairs are used, then signal integrity through differential signaling is improved, but device size and complexity increase
Solution Approach 1:
The invention extracts only the essential elements needed for signal transmission by using a single twisted pair instead of four pairs. The connector design removes unnecessary conductors and simplifies the contact structure to just two tuning fork contacts per connector, significantly reducing device complexity while maintaining signal integrity through careful contact geometry design.
Solution Approach 2:
The single twisted pair connector design serves multiple functions: it transmits both data and power over the same pair of conductors, and the coupler provides both mechanical connection and electrical polarity maintenance in a single component. This multi-functionality reduces overall system complexity compared to traditional four-pair Ethernet connectors.
3Area of stationary object
If connectors are designed for high-density panel configurations, then space utilization is improved, but contact alignment and polarity maintenance become more challenging
Solution Approach 1:
The contact alignment problem is solved by adding dimensional complexity to the contact geometry rather than increasing connector density in the panel plane. The three-dimensional tapered faces and offset positioning of contacts provide built-in alignment features that guide proper insertion and maintain polarity, enabling high-density configurations without sacrificing alignment precision.

AI summary
A coupler couples a first connector with a second connector wherein each of the connectors is coupled to exactly two electrical conductors. Each coupler can be utilized in a shielded (e.g., metal) or non-shielded (e.g. non-metal) form as appropriate to a specific application. Each coupler includes exactly one pair of pin contacts, preferably with a square or rectangular cross-section. Each end of the pin contacts includes four tapered faces that join at a flattened apex and are configured to be received by the tuning fork contact of the connector. The pair of pin contacts are offset from one another and cross one another within the coupler to maintain electrical polarity as electricity travels from the tuning fork contacts of a first connector to the pin contacts of the coupler and onward to the tuning fork contacts of a second connector.
