A hermaphroditic connector for use in single or multiple twisted-pair connectivity applications is constructed using a small number of parts having a simple but durable assembly. The connector housing comprises an elongated form factor that, when mated with a similar hermaphroditic connector, forms a rigid overlapping shield around the electrical contacts of the two connectors. While unmated, the conductive tines within the connector have a default curved profile that facilitates reliable connectivity with tines of a mating connector. When the connector is mated with a similar connector, the tines are deformed to a flatter profile by support plates within the connectors, yielding a shape more conducive to high-frequency signal applications. The shape of the tines also yields multiple in-line redundant contact points to ensure reliable connectivity without adding to the width of the connector.

Edge-coupled differential stripline connector

A communication plug configured to be mated with a communication outlet. The plug has first contacts configured to physically contact and form electrical connections with second contacts of the outlet. The plug also includes a substrate with wire contacts and first, second, third, and fourth layers. The first layer includes first conductors connecting a first portion of the first contacts with a first portion of the wire contacts. The fourth layer includes second conductors connecting a second portion of the first contacts with a second portion of the wire contacts. The second layer includes a first plurality of capacitor plates electrically connected to first selected ones of the first contacts. The third layer includes a second plurality of capacitor plates electrically connected to second selected ones of the first contacts. Each of the first plurality of capacitor plates forms a capacitor with at least one of the second plurality of capacitor plates.

High-speed data communications connector

A dust cap for use with a fiber optic connector. The connector has a ferrule comprising an optical fiber. The ferrule has an end portion that includes an end surface of the optical fiber through which optical signals are transmitted. The dust cap includes a cover and wiping material. The cover is removably positionable over the end portion of the ferrule. The wiping material is positioned at least partially inside the cover. The wiping material may be adjacent the end surface of the optical fiber when the cover is positioned over the end portion of the ferrule. The wiping material may be wiped across the end surface of the optical fiber when the cover is positioned over the end portion of the ferrule. The wiping material may be moveable with respect to the end surface of the optical fiber and may wipe thereacross when moved.

Methods and devices for preventing contamination of fiber optic connectors

Shields, wire connectors, crimping devices, and wire managers. At least some of the shields are used with a cable that includes a jacket surrounding wire pairs, and a different pair shield surrounding each wire pair. Such shields include a compressible member positioned adjacent end portions of a portion of the wire pairs. The compressible member presses a conductive member against the pair shield surrounding each wire pair in the portion of wire pairs. At least some of the wire connectors include a conductive body positionable alongside a selected wire having a connector surrounded circumferentially by an insulating jacket. The body includes a receptacle with a tapered opening defined between first and second edge portions of the body. As a portion of the selected wire passes through the opening into the receptacle, the first and second edge portions cut through the insulating jacket to contact the conductor.

Communications connector system

A communication connector including elongated contacts, and an optional flexible compensation circuit. The elongated contacts include a plurality of contact pairs. Each pair includes first and second contacts configured to transmit a differential signal. The elongated contacts may each have first and second portions with first and second heights, respectively. The first height is greater than the second height. The first portion of the first contact is positioned alongside the first portion of the second contact to capacitively couple the first and second contacts together. The optional flexible compensation circuit includes compensation circuitry configured to at least partially reduce crosstalk between the elongated contacts.

A substrate operable to construct a male-type connector, a female-type connector, and/or a multi-outlet module. The substrate has a plurality of circuits and an edge card male connector including contacts for each circuit. For each circuit, the substrate has a ground plane connected to one or more of the contacts for the circuit. The ground planes may be implemented as localized, electrically floating, isolated ground planes. The substrate may include multiple layers upon which portions of the circuits and ground planes may be disposed. The ground plane corresponding to each of the plurality of circuits may be located in close proximity to conductive elements of the circuit so as to provide a localized common ground to which energy can be conveyed from the conductive elements to thereby limit an amount of energy radiated outwardly from the conductive elements to surrounding conductors.
