A circuit interrupting device including a phase conductor, a neutral conductor, an interrupter configured to disconnect the phase conductor and the neutral conductor from a load, and a sensor configured to generate a signal indicative of current flowing through the phase conductor and the neutral conductor. The circuit interrupting device further includes a microcontroller that includes an electronic processor and is electrically connected to the first sensor and the interrupter. The microcontroller is configured to generate a reference signal, receive a first signal from the sensor, determine whether a difference between a voltage of the first signal and a voltage of the reference signal exceeds a threshold, determine whether the microcontroller has performed a ground fault self-test, and activate the interrupter when the difference exceeds the threshold and the microcontroller has not performed the ground fault self-test.

Ground fault circuit interrupter with integrated controller

An electrical module provides a plug receptacle for AC power and also converts AC power into DC power and provides DC output. The module may also provide one or more multimedia connectors. DC power may be provided from one module to another such that a single DC power supply may supply DC power for multiple modules.

Integrated modular multimedia system in wall-box format

An electrical connector adapted to receive a mating plug utilizes low-profile jack terminal contacts that can flex in their PCB-anchored base portions, which are substantially parallel to the PCB. Any bend in the distal connecting portion or in the intermediate transition portion of each terminal contact is gradual and forms an obtuse angle, thus minimizing stress concentrations. The contacts preferably are arranged in two oppositely facing and interdigitating rows of four contacts each. In one embodiment, the terminal contacts are anchored to the PCB by a contact cradle that constrains the base portion of each terminal contact at two spaced anchoring locations, allowing the base portion to flex therebetween. In another embodiment, the base portions of the terminal contacts are embedded in at least one elastomeric member, which is fitted to the PCB.

Method of making a communications jack

A multi-port telecommunications connector panel has an electrically conductive housing that defines a plurality of ports, each with a plug receiving cavity aligned with a respective set of jack contacts. The housing surrounds the sets of jack contacts individually and collectively to separate and isolate adjacent ports. Electrically conductive isolation barriers, which are electrically connected to and may be integral with the housing, separate adjacent sets of insulation displacement contacts, which are arranged in an offset pattern.

Telecommunications connector panel with interport crosstalk isolation

An electrical connector includes a housing having a plug receiving cavity with an open end for receiving a plug and with an inner end spaced from the open end, and having a forward chamber outside of the cavity and adjacent the open end. A mounting circuit board is in the housing adjacent the inner end. A plurality of pairs of electrical jack contacts have mounting ends engaging the mounting circuit board, plug contacting portions extending through the cavity from the mounting end toward the open end, and free ends extending from the contacting portion into the forward chamber. A compensation circuit board is mounted in the forward chamber of the housing outside of the plug receiving cavity, and has a compensation circuit with conductive pads. The free ends of the jack contacts engage the conductive pads. A spring in the forward chamber biases the compensation circuit board towards the free ends of the jack contacts.

Electrical connector with separate contact mounting and compensation boards

A connector for a communications system concentrates crosstalk in the front of a plug housing. The plug housing has front and rear ends. An internal chamber opens on the rear end and is defined by housing walls. A plurality of slots extend through one of the housing walls adjacent the front end and into the internal chamber. A plurality of contacts are mounted in the slots for movement between retracted positions spaced from the internal chamber and inserted positions extending into the internal chamber. An insert assembly has at least one insert member disposed adjacent at least one of the plurality of contacts. The insert assembly is made of a higher dielectric material than the plug housing.

Dielectric insert assembly for a communication connector to optimize crosstalk

An apparatus/system for use in coupling power from a power supply to a device over a network transmission medium is provided. The coupling apparatus/system generally includes one or more common mode chokes that feature a first winding and a second winding, the first winding being electrically connected between the first terminal of the power supply and the first electrical conductor of the network transmission medium, and the second winding being coupled between the first terminal of the power supply and the first electrical conductor of the network transmission medium. The common mode choke generally includes at least one core for coupling the first and second windings of the one or more common mode chokes. An RJ45 to 110 IDC modular connector may be connected to a printed circuit board used to transfer high speed signals for telecommunication interface media connections. The printed circuit board is configured to help reduce near-end crosstalk (NEXT) without compromising impedance. DC power is coupled upon the signal line by utilizing a wideband high impedance common mode choke design.

Apparatus and method for communication system

The present invention is related to the modular plug housing insert device that makes electrical contact to a telecommunication plug to complete an interface media connection. The positional relationship of the conductors in the modular plug housing insert device are arranged to from capacitance, such that the Near-end Crosstalk (NEXT) and Far End Crosstalk (FEXT) is reduced without compromising impedance.

Dual reactance low noise modular connector insert

A wire connecting unit for an electrical connector for communication and data transmission systems includes a circuit board with a free and a near end and having four pairs of contacts mounted in a cantilever manner. The wire connecting unit has specific contact configurations that reduce crosstalk, attenuation, propagation delay, and other electrical and magnetic properties that interfere with communication and data transmission. In one embodiment, a first row of contacts extends generally upwardly and backwardly from the free end of the printed circuit board toward the near end, and a second row of contacts placed further from the free end of the printed circuit board than the first row of contacts extends generally upwardly and backwardly from the free end toward the near end. Each adjacent contact can have only a single push foot that extends laterally and outwardly from its proximal end, remote from the other contact in the respective pair, allowing the contacts to be placed relatively close together to further reduce the electrical and magnetic properties that interfere with communication and data transmission.
