A connector assembly comprises a first connector and a second connector. The first connector includes a first housing and first connection terminals. The first housing defines a receiving cavity with an open upper end. A second connector includes a second housing and second connection terminals. The second housing is adapted to be partially inserted into the receiving cavity such that the second connection terminals electrically contact with the first connection terminals. The second housing defines an oblique-insertion restriction structure protruding from a remaining uninserted portion of the second housing. The restriction structure is sized and positioned to abut against an upper end surface of the first housing in a condition in which the second housing is inserted into the receiving cavity in an oblique posture relative to the first housing.

A connector assembly comprises a first connector and a second connector mateable with each other. The first connector comprises a first shell which has a first mateable portion and a first key. The first key is located outward of the first mateable portion. The second connector comprises a second shell which has a second mateable portion and comprises a housing which has a projecting end and a second key. The projecting end faces the first connector when the first connector and the second connector are under a separated state where they are separated from each other. The second key is a groove which extends from the projecting end. When the first connector and the second connector are mated with each other, the second mateable portion is received in the first mateable portion, and the first key is received in the second key.

An electrical connector includes wafer assemblies coupled to a housing.

Each leadframe has signal contacts with mating ends extending from the wafer body for mating with mating signal contacts of a mating electrical connector. The mating ends are twisted 45° to define twisted mating interfaces. Each ground frame has ground shields extending from a ground plate along the mating ends of the signal contacts. The ground shields are twisted 45° relative to the ground plate to define twisted shield zones along the mating ends of the signal contacts.

An electrical connector assembly is applied to be disposed on a circuit board. The electrical connector assembly includes an electrical connector and a grounding metal member that is sleeved around an outer side of the electrical connector. The grounding metal member has a first surrounding segment and a second surrounding segment that outwardly extends from an end of the first surrounding segment. The second surrounding segment has a shielding portion being ring-shaped and a plurality of extension portions that extend from the shielding portion. The grounding metal member is configured to be connected to a grounding circuit of the circuit board through the shielding portion and the extension portions.

Provided is a connector and a connector assembly with improved properties of a frame while the number of components is further reduced. The connector can be fitted with a counter connector and includes: a frame including a side wall which surrounds the counter connector; a first terminal and a second terminal which are situated inside the frame; and a blocking portion disposed between the first terminal and the second terminal. The side wall seamlessly continues over an entire periphery of the frame, the frame and the blocking portion are constituted of a same member to be integrated with each other, the blocking portion has a joint portion which joins one end portion to another end portion of the frame, and the joint portion is fixed to the board while being in contact with the board continuously from the one end portion to the other end portion of the frame.

Provided is a connector assembly capable of suppressing deformation and breakage of a connector that may occur when one of connectors displaces in a connector fitting state. The connector assembly is configured such that a first connector is fitted with a second connector, with one of the first connector and the second connector entering an inside of another, the first connector includes a projection portion that projects to a side on which the second connector is disposed in a fitting direction of the first connector and the second connector, the second connector includes a restriction portion that restricts displacement of the second connector in an intersecting direction intersecting the fitting direction, and, in a state where the first connector is fitted with the second connector, the restriction portion contacts the projection portion in the intersecting direction to restrict displacement of the second connector.

A connector assembly comprises a connector and a mating connector mateable with each other. The connector comprises a first terminal, a second terminal and a shield portion. The shield portion is located between the first terminal and the second terminal in the pitch direction. The mating connector comprises a first mating terminal, a second mating terminal and a mating shield portion. The mating shield portion is located between the first mating terminal and the second mating terminal in the pitch direction. One of the shield portion and the mating shield portion has a plate portion, and a remaining one of the shield portion and the mating shield portion has a mating plate portion. Under the mated state, a position of the plate portion in the pitch direction is equal to or overlaps with another position of the mating plate portion in the pitch direction.

A communication system having a circuit board with an airflow opening includes a receptacle cage configured to be mounted to the circuit board adjacent a communication connector. The receptacle cage has walls including a front wall, a rear wall and side walls defining a cavity. A module channel is defined in the cavity configured to receive a pluggable module. The module channel has a module port at the front wall that receives the pluggable module. An airflow channel is defined by at least one of the walls of the receptacle cage located between the module channel and the circuit board. The airflow channel is configured to be in flow communication with the airflow opening in the circuit board for cooling the pluggable module in the module channel. The airflow channel has an airflow port at the front wall.

An electric connector assembly includes an insulating housing, a plurality of rows of contact terminals disposed in the insulating housing and including a plurality of signal terminals and a plurality of ground terminals, and a conductive shell assembled on the insulating housing. The conductive shell contacts and is connected with the ground terminals to electrically connect the ground terminals together.
