A device, network and method wherein a standard wireless modem is coupled to wiring for carrying a wireless baseband signal that may be OFDM based, and may be directly generated by the wireless IF modem, or extracted from the modem RF signal. The wiring may be a building utility wiring, such as telephone, AC power or CATV wiring. The baseband signal is carried simultaneously with the utility service signal over the utility wiring using Frequency Division Multiplexing. The device may be enclosed with a data unit, a standalone dedicated enclosure, within an outlet or as a plug-in outlet adapter. Data units may couple the device by a wiring port such as standard data connector, or via wireless connection. The device may be locally powered or via a power signal carried over the wiring. This abstract is not intended to limit or construe the scope of the claims.

A card connector for receiving a card includes an insulating housing, a plurality of conductive terminals received in the insulating housing, a first switch terminal, a second switch terminal and a shielding shell covered on the insulating housing. The insulating housing defines a first switch groove, a second switch groove, a first fastening groove and a second fastening groove. The first switch terminal includes a first fastening portion fastened in the first fastening groove, a first locating portion located in the first switch groove, and a first contact portion hung over the insulating housing. The second switch terminal includes a second fastening portion fastened in the second fastening groove, a second locating portion located in the second switch groove, and a second contact portion hung over the insulating housing to electrically contact with the first contact portion under the pressure of the card.

A calibration adapter with coaxial connector for connecting to a complementary coaxial connector of a device to be calibrated, where the coaxial connector has an inner conductor part, an outer conductor part arranged coaxially thereto, and a male termination. The calibration adapter has a drum where at least two calibration standards are arranged, the drum is rotatably arranged on a pin connected centrally to a first cap such that a longitudinal axis of the pin is flush with a longitudinal axis of the first cap. The coaxial connector with a second termination opposite the male termination, is connected eccentrically to the longitudinal axis of the first cap, and the at least two calibration standards are arranged in the drum such that by the rotation of the drum relative to the first cap, the second termination can be optionally connected to one of the calibration standards.

A card connector includes an insulating housing, a plurality of contacts, a projection and a detecting contact set. The insulating housing includes a bottom wall, a right wall and a left wall for defining a receiving space. The contacts are received in the insulating housing. The projection is protruded from the right wall and into the receiving space, which includes a slanting surface slanted relative to the right wall. The detecting contact set is fixed in the insulating housing, which includes a contacting arm protruding from the slating surface of the projection and into the receiving space. Due to the contacting arm of the detecting contact set is protruded from the slanting surface of the projection in the receiving space, the detecting contact set will be actuated while a card is inserted into the receiving space correctly and completely. Since, the detecting accuracy of the card connector is improved.

An active connector is provided that allows for simple designing of devices for high-speed wideband pulse signal transmission without specialized technical know-how in the use of connectors. A connector base has a first connection terminal and a second connection terminal, and houses a first matching circuit, a second matching circuit, and a buffer circuit. The first connection terminal and the second connection terminal can be used as an internal port electrically coupled to a device circuit and an external port electrically coupled to a transmission line, respectively. An input signal inputted into the first connection terminal is supplied to the first matching circuit. The second matching circuit supplies an output signal to the second connection terminal. A buffer circuit between the first matching circuit and the second matching circuit inhibits mutual influences between the input signal and the output signal.

A structure for use with data network management systems uses a plurality of cables interconnecting patch panels, network devices and end-user devices and further utilizes integrated circuits to monitor the status of these end-user devices. The structure includes respective primary (36) and secondary (45) circuit boards. A plurality of connective jacks (31) are mounted on the primary circuit board and these jacks are interconnected to switches and other patch panels within the network. Wires from the jacks extend to and connect with end-user devices and a secondary circuit board is spaced apart from the primary circuit board so as to define a hollow nest (42) within the patch panel assembly that houses and protects integrated circuits (45, 52) and the like.

A plug receptacle includes a housing having at least one outlet unit to which a plug is adapted to be connected to supply a DC power to the plug, and a cable, connected to the housing, for supplying the DC power to the housing. The outlet unit includes a plug-receiving portion having a plurality of substantially circular pin-inserting holes into which plug pins of the plug are inserted and an insertion groove formed to surround a periphery of the plug-receiving portion. The plug-receiving portion has a substantially quadrangular shape viewed from a front side thereof. The insertion groove is adapted to receive a surrounding wall of the plug and has a substantially quadrangular shape viewed from the front side. The pin-receiving holes are arranged along one side of the plug-receiving portion serving as a reference side and offset closer to the reference side than an opposite side to the reference side.

A power connector includes an insulative housing, a power contact and a switch retained to the insulative housing. The insulative housing has a front surface, a first cavity and a second cavity recessed from the front surface. The power contact has a mating portion protruding into the first cavity. The switch has a button received in the second cavity and a connecting contact engaging with the button. The button has a lever protruding inwardly from an inner side thereof. The lever defines a through hole, and the connecting contact extends through the through hole and moves in the through hole in a pressing process of the button to make the connecting contact electrically connect or disconnect with the power contact.
