A shielded I/O connector that supports high density connections. The shielded connector has a cage with channels. At least a first channel is configured to receive a transceiver such that it may be plugged into a port in a connector housing at an end of the cage. At least a second channel is configured to dissipate heat by enabling air to flow adjacent the transceiver. The rate of air flow in the second channel is increased with a channel in the connector housing that connects with the second channel. Air may exit the housing channel through openings in rear surfaces of the cage or through openings that bound the housing channel.

High performance stacked connector

A shielded I/O connector that supports high density connections. The shielded connector has a cage with channels. At least a first channel is configured to receive a transceiver such that it may be plugged into a port in a connector housing at an end of the cage. At least a second channel is configured to dissipate heat by enabling air to flow adjacent the transceiver. The rate of air flow in the second channel is increased with a diverter at the end of the second channel to smooth the flow of air through the second channel and out of one or more orifices. The diverter may be simply formed by shaping the housing of a connector at an end of the cage. The orifices may be formed by channel in the connector housing and openings in surfaces of the cage that bound the second channel or the housing channel.

An electrical connector includes a connector housing and first and second differential contacts. A contact cavity is defined between opposed sides and opposed endwalls. First support members and second support members extend from the opposed sides into the contact cavity. Each of first support members is shorter than each of the second support members. The first and second differential contacts define a differential pair retained within the contact cavity. The first and second differential contacts are retained between two of the first support members. At least a portion of the first and second differential contacts extends past a level of the first support members. The portion(s) of the first and second differential contacts that extends past the level of first support members is exposed to air.

Electrical connector assembly having high speed signal pairs

An electrical communication system includes a printed circuit board (PCB) having first and second ground plates and a plurality of signal vias and a plurality of ground vias extending between and through the first and second ground plates. Each of the plurality of signal vias are electrically connected to a respective conductive trace on a surface of the PCB. Cables connect to the PCB at a right angle, with a connector attached to an opposite side of the PCB. Each cable has two signal wires and a ground wire extending therefrom. The two signal wires define a differential pair. The signal wires are symmetrical with respect to the ground wire. Each of the signal wires electrically connects to a respective one of the plurality of signal vias. The ground wire connects to one of the plurality of ground vias. The cables are offset with respect to one another on the first and second ground plates and within the PCB.

System for connecting electrical cables to a printed circuit board

An electrical connector including a connector housing having opposite mating and loading faces and a mating axis extending therebetween. The connector housing has interior walls that oppose each other with a contact cavity therebetween. The electrical connector also includes a retention insert that is sized and shaped to be advanced through the loading face and positioned within the contact cavity. The retention insert has an outer engagement surface. The electrical connector also includes first and second rows of mating contacts that are separated by the retention insert. The contact cavity has a component-receiving region that exists between the first and second rows of mating contacts and is accessible through the mating face. The mating contacts of the first and second rows are oriented to extend lengthwise along the mating axis and are held between the engagement surface of the retention insert and respective interior walls.

Electrical connectors and receptacle assemblies having retention inserts

A card edge connector is provided for mating with a printed circuit board (PCB) having a card edge. The connector includes a housing having an elongate card slot and a mounting side. The card slot extends a slot length and is configured to receive the card edge of the PCB therein. The mounting side extends a side length and a width. The side length of the mounting side extends in a direction that extends along a direction of the slot length of the card slot. Signal contacts are held by the housing. The signal contacts include first signal contacts and second signal contacts. The first and second signal contacts have respective first and second signal mounting segments that are arranged in first and second signal rows, respectively, that extend along the side length of the mounting side of the housing. The first and second signal rows are spaced apart from each other along the width of the mounting side. Ground contacts are held by the housing. The ground contacts include ground mounting segments arranged in a ground row that extends along the side length of the mounting side. The ground row extends between the first and second signal rows along the width of the mounting side of the housing.

Card edge connector

A modular board to board mezzanine ball grid array BGA connector includes a plug, a receptacle and if needed an adapter. The plug and the receptacle can be made form the same base pieces to accommodate different stack heights. If a greater stack height is needed, spacers can be used in the plug and the receptacle to accommodates a greater selected stack height. The plug and the receptacle both include a base having an interstitial diamond recesses in which the solder balls are disposed and in which one end of a contact is inserted. The plug may further include a plug cover that can be connected to the base, and the receptacle may include a receptacle cover that fits over its base. The plug can have a plug contact assembly, and the receptacle can have a receptacle contact assembly. The plug and the receptacle can be mated by mating the plug cover to the receptacle cover and the receptacle contacts to the plug contacts. If a larger stack height is desired, a spacer can be attached to the base of either or both the plug or the receptacle to achieve a larger stack height.
