The present disclosure is directed to connectors and, more specifically, to connectors for use with a single-twisted pair of conductors.
A single twisted pair of conductors can be used to transmit data and/or power over a communications network that includes, for example, computers, servers, cameras, televisions, and other electronic devices including those on the internet of things (IoT), etc. In the past, this has been performed through use of Ethernet cables and connectors which typically include four pairs of conductors that are used to transmit four differential signals. Differential signaling techniques, where each signal is transmitted over a balanced pair of conductors, are used because differential signals may be impacted less by external noise sources and internal noises sources, such as crosstalk, as compared to signals that are transmitted over unbalanced conductors. In Ethernet cables, the insulated conductors of each differential pair are tightly twisted about each other to form four twisted pairs of conductors, and these four twisted pairs may be further twisted about each other in a so-called “core twist.” A separator may be provided that is used to separate at least one of the twisted pairs from at least one other of the twisted pairs. The four twisted pairs and any separator may be enclosed in a protective jacket. Ethernet cables are connectorized with Ethernet connectors; a single Ethernet connector is configured to accommodate all four twisted pairs of conductors. However, it is possible that data and/or power transfer can be effectively supported through a singled twisted pair of conductors with its own more compact connector and cable. Accordingly, a connector design different from a standard Ethernet connector is needed.
A family of connectors to accommodate a single twisted pair of conductors is disclosed herein. The family of connectors includes a free connector, a fixed connector, and an adapter; the free and/or fixed connectors can be modified to accommodate various patch cord and mounting configurations. In certain embodiments, the one or more of the family of connectors adopts an RJ 45 style connector or RJ 45 style jack/receptacle configuration in a reduced footprint, e.g. one-half, one-third or one-quarter the size of a standard RJ 45 connector or jack/receptacle.
An aspect of the present disclosure is directed to a connector including an RJ 45 style connector housing and only first and second insulation piercing contacts. The RJ 45 style connector housing is one-half, one-third, or one-quarter the size of a standard RJ 45 connector. The first and second contacts are contained within the connector housing and are configured to be electrically coupled to a single twisted pair of conductors.
Another aspect of the present disclosure is directed to a connector that includes an RJ 45 style jack/receptacle body portion and only first and second contacts. The body portion includes a port. Further, the body portion is one-half, one-third, or one-quarter the size of a standard RJ 45 jack/receptacle. The first and second contacts are accessible via the port and are configured to be electrically coupled to a single twisted pair of conductors or to first and second contacts of a printed circuit board.
Another aspect of the present disclosure is directed to an adapter for coupling two single twisted pairs of conductors. The adapter includes a body portion having first and second ports. Each of the first and second ports includes only first and second contacts that are accessible via the ports. The first and second contacts or the first port are electrically coupled to the first and second contacts of the second port. Each of the first and second ports is configured to interface with a two-contact only connector.
Still another aspect of the present disclosure is directed to patch cord that includes a cable having a single pair of twisted conductors. Each of the conductors includes a first end and a second end. The first ends are coupled to an RJ 45 style connector or to an RJ 45 style jack/receptacle. Similarly, the second ends of the conductors are coupled to an RJ 45 style connector or to an RJ 45 style jack/receptacle. The RJ 45 style connector and the RJ 45 style jack/receptacle are one-half, one-third or one-quarter the size of a standard RJ 45 connector or jack/receptacle.
A family of connectors to accommodate a single twisted pair of conductors is disclosed herein. The family of connectors includes a free connector, a fixed connector, and an adapter; the free and/or fixed connectors can be modified to accommodate various patch cord and mounting configurations. In certain embodiments, the one or more of the family of connectors adopts an RJ 45 style connector or RJ 45 style jack/receptacle configuration in a reduced footprint, e.g. one-half, one-third or one-quarter the size of a standard RJ 45 connector or jack/receptacle.
