An electrical connector is attached to a wiring substrate and mated with a counterpart connector connected to a signal transmission medium. A shell of the electrical connector has a pair of wall parts that contact a ground member on the counterpart connector. One wall part distant from the signal transmission medium includes a first side plate that has one end attached to a ground conductive path of the wiring substrate and extends in a direction away from the wiring substrate, a joining part that has one end joined to another end of the first side plate, and a second side plate that has one end joined to another end of the joining part and extends in a direction closer to the wiring substrate. The second side plate has a contact piece that extends in a direction away from the wiring substrate and elastically contacts the ground member.

A socket having a housing, a plurality of contacts, a plurality of insulating members and a plurality of conductive resin members is described. The housing is in a box shape with an opening and is provided with a matrix of penetration holes at a bottom portion. The plurality of contacts include contacts for ground and respective pairs of contacts for high-speed differential transmission. The plurality of insulating members support the plurality of contacts and are pressed into the housing so that the contacts are exposed on an opposite side of the opening from the penetration holes of the housing. The plurality of conductive resin members are fitted at positions of the plurality of insulating members in contact with the contacts for ground.

An optical receptacle connector includes a receptacle housing defining a contact cavity, an optical cavity, and a card slot at a front of the receptacle housing configured to receive an edge of an optical module circuit board. A contact assembly having receptacle contacts is received in the contact cavity and extend into the card slot to supply power to the pluggable optical generator module to operate a light source. The optical receptacle connector includes a receive optical connector coupled to the receptacle housing having a ferrule holding at least one optical fiber configured to be mated with a supply optical connector of the pluggable optical generator module to receive optical signals from the supply optical connector.

An electrical connector includes a differential signal pair. A portion of each terminal is disposed in an insulative housing and an electrically conductive shield extends around at least a portion of the terminals and a least a portion of the housing. The housing may have a lower surface and a projection extending downward from the lower surface between a portion of a vertical section of each of the terminals. The terminals may have an angled section including a vertical portion having a first width, an angled portion narrower than the vertical portion, and a horizontal portion narrower than the angled portion. The housing may have a housing mating component spaced from a housing body component and aligned with but spaced from the terminals. The terminals may have a planar termination section with a first portion wider than a second portion.

A cable assembly comprising a connector with a termination that enables high density and high signal integrity. Shields of cables are terminated to a paddle card via a conductive structure attached to a surface of the paddle card. The signal conductors of the cables are terminated to pads on the paddle card that are exposed within openings of the conductive structure. Such a structure creates a ground structure per cable that provides low insertion loss and low crosstalk, even when multiple cables are aligned side by side and terminated in one or more rows. The cables may be drainless, enabling a large number of cables, such as eight cables, to be packed within the width of a paddle card specified in high density standards such as QSFP-DD or OSFP. The cables may nonetheless have large diameter signal conductors, enabling 2.5 or 3 meter assemblies with less than 17 dB insertion loss.
