摘要:
A surge protector connector comprises a surge protector having a front plate, a rear plate, and hollow cylindrical body bridging the front and rear plates. A coaxial cable connector interface extends from the front plate, and the connector interface is constructed and arranged to detachably engage with a mating coaxial cable connector at the end of a first coaxial cable. A cable attachment interface extends from the rear plate, and the cable attachment interface is constructed and arranged to attach directly to a prepared end of a second coaxial cable free of another coaxial cable connector interface. The surge protector connector further includes coaxial inner and outer conductors extending through the hollow cylindrical body and extending between the cable attachment interface and the coaxial cable connector interface. The surge protector includes a curvilinear quarter-wavelength shorting stub having a first portion extending in a generally radial direction from the inner conductor through a gap in the outer conductor and a second portion extending in a generally annular direction circumscribing the outer conductor between the outer conductor and the cylindrical body.

This application describes a jack for improving crosstalk attenuation. The jack has a housing, a foil at least partially surrounding the housing, a printed circuit board, and at least one pair of insulation displacement contacts and vias. Each pair of insulation contacts and vias are associated with a differential signal. A conductive trace stub is routed on the printed circuit board near the edge of the board proximate to the foil in order to at least partially balance the coupling from one of the insulation displacement contacts and vias of a pair to the foil with the other insulation displacement contact and via of the pair by electrically connecting the trace stub to the via that is further from the foil.

A communication jack has a housing with a face having a plug receiving aperture. A plurality of conductive path pairs extends from corresponding plug interface contacts located at the plug receiving aperture to corresponding output terminals. A first circuit board is connected to the plug interface contacts and a second circuit board is connected to the plug interface contacts and the output terminals. The first circuit board has a first single stage of crosstalk compensation with opposite polarity of the crosstalk of a plug for a first combination of the conductive path pairs. The second circuit board includes a second single stage of opposite polarity crosstalk compensation for some of the conductive path pairs not compensated on the first circuit board. The stages cancel substantially all of the crosstalk caused by the plug, for the signal operating frequencies, for corresponding combinations of the conductive path pairs.

This application describes a jack for improving crosstalk attenuation. The jack has a housing, a foil at least partially surrounding the housing, wherein the foil is made up of a first section separated and conductively isolated from a second section by a gap or made up of a first metalized section separated and conductively isolated from a second metalized section by a non-metalized section whereby common mode noise caused by the capacitive coupling between foils of a series of adjacent jacks is reduced.

A communication connector uses compensation circuitry to compensate for crosstalk in a network connection. Portions of the compensation circuitry are placed on a flexible circuit board that makes conductive contact with plug interface contacts of the connector. Additional compensation circuitry is provided on a rigid circuit board within the connector.

A pair manager for use in securing a twin-axial cable to a printed circuit board is described. The pair manager comprises a generally block-shaped portion containing a pair of channels. The channels extend from the front face to the rear face of the block-shaped portion. An integral flange and a pair of integral fingers extend perpendicularly from the front face of the block-shaped portion. The flange extends generally from the center of the front face and the fingers extend from opposite edges of the front face. The fingers and flange function as a partial shield cavity around each pair of conductors. This design helps to maintain better impedance matching when connecting twin-axial cables to a printed circuit board.
