Provided is a connector including a surrounding wall with an improved strength against an outward force.

The connector of the invention includes a contact that contacts a counter contact of a counter connector, a housing to which the contact is fitted and attached, and a surrounding wall disposed to surround the housing. A gap is provided between the housing and the surrounding wall, and in a connector fitting state, the surrounding wall is in contact with a counter surrounding wall of the counter connector that has entered the gap. The surrounding wall is provided with a protrusion portion protruding outward in a second direction intersecting a first direction, and an end portion on a board side of the protrusion portion in the first direction is in contact with a board.

An apparatus comprising an interconnect comprising a conductive core; a first conductive layer connected to the conductive core and extending parallel to the conductive core towards a first end of the conductive core; a second conductive layer connected to the conductive core and extending parallel to the conductive core towards a second end of the conductive core; a first non-conductive layer between the conductive core and the first conductive layer; and a second non-conductive layer between the first conductive layer and the second conductive layer.

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.

A receptacle connector includes a fixed housing, a movable housing, a plurality of receptacle contacts disposed across the fixed housing and the movable housing, and a receptacle hold-down that restricts upward movement of the movable housing from the fixed housing. The movable housing is movable in a pitch direction of the plurality of receptacle contacts in relation to the fixed housing. The receptacle hold-down includes two housing fixing parts to be fixed to the fixed housing, and an elastic deformation part supported by the housing fixing parts and opposed to the movable housing in an insertion and removal direction. The elastic deformation part is opposed to the movable housing in the pitch direction and elastically deformable in the pitch direction.

A terminal placement region of the cartridge is divided into an upper region and a lower region, and the cartridge includes a plurality of terminals placed in the upper region, a plurality of terminals placed in the lower region, and a plurality of long terminals across the upper region and the lower region. The long terminals are a ground terminal, a chip-enable terminal, a power supply terminal, or a reset terminal. A strobe terminal and a clock terminal are arranged one above the other. Two data input/output terminals are arranged one above the other, and four sets of data input/output terminals arranged one above the other are present. A long terminal is near the strobe terminal and the clock terminal arranged one above the other, and a long terminal is near the two data input/output terminals arranged one above the other.

An electric connection socket for relaying electric signals between a circuit substrate and an electric component includes: a metal housing which has a through hole enabling communication between the top surface and the bottom surface thereof, and on the top surface of which the electric component is mounted and on the bottom surface of which the circuit substrate is mounted; and a signal pin inserted into the through hole to configure a coaxial line between the inner wall surfaces of the through hole, and which is electrically connected at one end to a signal path pad electrode of the circuit substrate and is electrically connected at the other end to a signal path terminal of the electric component. The metal housing is arranged on the circuit substrate such that an air gap is formed between the bottom surface of the metal housing and the top surface of the circuit substrate.

An electrical receptacle connector is mounted within a metallic cage for mating with a QSFP module received within the cage. The contacts of the cable receptacle connector are arranged with two groups, of which one are connected to the printed circuit board on which the cage is mounted, and the other are connected to the wires which are further connected to a board-mount receptacle connector mounted on another printed circuit board on which the CPU (Central Processing Unit) socket is mounted. Each board-mount receptacle connector corresponds to more than one cable receptacle connector.

An electrical connector grounding structure includes an electrically insulative terminal holder block having a rectangular base, a mating structure and a fixing structure, conducting terminals positioned in the rectangular base with contact tips thereof extended to the mating structure and connection tips thereof bonded to a predetermined circuit board, a grounding member having a first contact structure, a positioning structure positioned in the fixing structure and a bonding structure bonded to the circuit board, and a shielding shell covering the electrically insulative terminal holder block and having a second contact structure set in contact with the first contact structure to form a ground loop that guides out electromagnetic waves and crosstalk interference generated during signal transmission.

A terminal placement region of the cartridge is divided into an upper region and a lower region, and the cartridge includes a plurality of terminals placed in the upper region, a plurality of terminals placed in the lower region, and a plurality of long terminals across the upper region and the lower region. The long terminals are a ground terminal, a chip-enable terminal, a power supply terminal, or a reset terminal. A strobe terminal and a clock terminal are arranged one above the other. Two data input/output terminals are arranged one above the other, and four sets of data input/output terminals arranged one above the other are present. A long terminal is near the strobe terminal and the clock terminal arranged one above the other, and a long terminal is near the two data input/output terminals arranged one above the other.

A contact assembly for an electrical connector includes a contact positioner having contact support walls holding a contact array. The contact array includes signal contacts and ground contacts interspersed with the signal contacts. The signal contacts include mating ends configured to be mated with a mating electrical connector and mounting ends configured to be terminated to a host circuit board. The signal contacts include transition portions between the mating ends and the mounting ends. The ground contacts include mating ends, mounting ends, and transition portions between the mating ends and the mounting ends. The contract assembly includes a ground bus wire extending transversely across the contact array. The ground bus wire is electrically connected to each of the ground contacts. The ground bus wire is electrically isolated from each of the signal contacts.
