  • Patent number: 10424874
    Abstract: A modular jack connector compensates for plug characteristics via a controlled primary compensation in the immediate vicinity of the connector interface. A jack contact assembly is positioned within a jack housing and includes first and second sets of elongate contacts each having a plug contact portion and a signal output portion. Each elongate contact is configured such that their respective plug contact portions are coplanar and a signal path is defined between their plug contact portions and their signal output portions. A flexible circuit board is coupled proximate to the plug contact portions, and configured to provide capacitance compensation between respective contacts engaged thereby, wherein the capacitance compensation is offset from a signal path defined between the plug contact portions and the corresponding signal output portions.

  • Patent number: 6676423
    Abstract: An electrical connector assembly adapted to be mounted on a substrate having a ground region including a jack defining a plug-receiving receptacle, at least one contact having a contact portion situated in the receptacle, a shield surrounding at least a portion of the jack and a shorting bar arranged in electrical connection with the contact(s) for discharging static charge from a plug upon its insertion into the receptacle and contact between the plug and the contact(s). The shorting bar is arranged in a channel in an outer housing part of the jack and in engagement with end portions of contacts received in slots in a comb portion of the outer housing part. The shield is adapted to be connected to the ground region of the substrate whereby the shorting bar is electrically connected to the shield.

  • Patent number: 6428361
    Abstract: Connector assembly including a jack defining a plug-receiving receptacle and a shield arranged around the jack. The jack includes a printed circuit board component including a printed circuit board, a first set of contacts each including a contact portion arranged in the receptacle and a board portion connected to the printed circuit board, and a second set of contacts each including a terminal portion adapted for mounting to a planar surface of a substrate and a board portion connected to the printed circuit board. The printed circuit board includes a wiring pattern for electrically coupling the first and second sets of contacts. The terminal portions extend rearwardly and downward from the jack and have a co-planar portion.

  • Patent number: 6368159
    Abstract: The new modular jack is mounted to a PC board to overlie an LED on this board. The jack includes a light pipe having a light-entry zone in its bottom surface, a first light reflection zone in its rear surface, a light indicator zone in its front surface and a longitudinal axis in the rear-to-front direction. The light pipe further includes in its top surface a second light reflection zone situated forward of the first light reflection zone, the first and second light reflection zones positioned to receive light from the LED and to reflect same forward to the light indicator zone which is visible at the front of the jack.

  • Patent number: 6196879
    Abstract: A connector assembly for surface mounting on a substrate including a jack and an optional shield surrounding the jack. The jack includes a housing defining a plug-receiving receptacle, contact/terminal members having a contact portion situated in the receptacle, a terminal portion extending from the housing and adapted to be surface mounted to the substrate, and an intermediate portion between the contact portion and the terminal portion. The intermediate portions of the contact/terminals members are retained or entrapped in the housing in fixed positions such that the terminal portions of the contact/terminals members extend downward and rearward from the housing in a common plane. To this end, the housing includes channels in which the intermediate portions of the contact/terminal members are placed such that the terminal portions extend from the channels at an angle to a bottom surface of the housing.

  • Patent number: 5896480
    Abstract: An opto-electric jack is provided which can be used as a drop-in replacement for a standard electrical jack such as an RJ-type or D-subminiature type jack. The opto-electric jack includes housing having a receptacle for receiving an optical plug which is coupled to a fiber optic cable, and a plurality of electrical terminals for connection to an electrical circuit. Preferably, the terminals are arranged in a predetermined array which corresponds to the terminal array (or footprint) of a standard electrical jack. An opto-electric conversion circuit is disposed within the housing, and is operable to convert optical signals received from the optical plug into electrical signals for transmission to the electrical circuit via the terminals, and to convert electrical signals received from the electrical circuit via the terminals into optical signals which are transmitted to the optical plug.
