Electrical connector assemblies are provided that include electrical connectors having electrical contacts that have receptacle mating ends are provided. The connector housings of the provided electrical connectors include alignment members that are capable of performing staged alignment of components of the electrical connector assemblies. The provided electrical connector assemblies and the electrical connectors provided therein are capable of operating at a data transfer rate of forty gigabits per second with worst case multi-active cross talk that does not exceed a range of about two percent to about four percent.

An electrical connector includes: an insulative housing; two rows of contacts retained in the insulative housing, each contact having an elastic arm and a soldering tail; a shielding assembly retained in the insulative housing and located between the two rows of contacts; plural cables having front ends connected with the soldering tails of corresponding contacts; a first shell covering the insulative housing; and a second shell and a third shell, wherein the second shell has a pair of side frame portions located by end faces of the insulative housing and a rear plate, the third shell has a front frame portion and a rear plate, and the front frame portion and the rear plate of the third shell and the rear plate of the second shell together entirely enclose and shield the soldering tails of the contacts and the front ends of the cables.

An electrical connector includes a housing formed of a fixed housing and a movable housing movable relative to the fixed housing. The connector further includes a terminal. The terminal includes a connecting portion to be connected to the electrical circuit board and a contact portion to be contacted with the mating connecting member. The terminal further includes a fixed side held portion, a movable side held portion, and an elastic portion. The connecting structure further includes a regulating portion for regulating the elastic portion from elastically deforming within a specific elastic deformation range. The elastic portion is configured to have a specific elastic deformation range. When the electrical connector is connected to the mating connecting member, the spring force is smaller than a holding force between the contact portion of the terminal and the mating connecting member in a direction that the electrical connector is pulled out.

A card edge connector with members configured to secure a mating component so as to improve the connector’s reliability. The connector housing may have a slot configured to receive the mating component. The slot has a first portion configured to receive a front edge of the mating component, and second portions extending from opposite ends of the first portion and configured to receive side edges of the mating component. Members are disposed in the housing and have beams curving into respective second portions of the slot. The beams of the members are configured to restrain movement of the mating component when the mating component is inserted into the slot. Such a configuration enables more reliable connections and improves the connector’s shock resistance while being compatible with mating components having a variety of sizes.

A plug connector includes: an insulative housing including a main body, a reinforcement projecting forward from the main body, and a pair of baffle plates; and a printed circuit board partially received in the insulative housing, the printed circuit board extending forward from the main body and beyond the reinforcement, the reinforcement wrapping on the printed circuit board, wherein a width of a front end of the printed circuit board exposed outside the main body in a horizontal direction is greater than a width of the reinforcement, and a limiting groove is formed between the baffle plate and the printed circuit board for guiding the plug connector to mate with a socket connector.

A locking mechanism for securing different expansion cards in a slot of a chassis of a computing device is disclosed. The locking mechanism includes a base and a main body. The base is coupled to the chassis and movable between an open position and a closed position. The main body is coupled to the base and movable between a first orientation and a second orientation. When the base is in the closed position and the main body is in the first orientation, a first mating feature of the main body engages an expansion card having a first form factor inserted into the slot. When the base is in the closed position and the main body is in the second orientation, the second mating feature engages an expansion card having a second form factor inserted into the slot of the chassis.

An M.2 fastening system has an M.2 riser card with two module-receiving sides and a plurality of adjustment positions. The M.2 fastening system further has a pair of M.2 fasteners mounted respectively on the module-receiving sides. Each M.2 fastener has a main body defined by a top surface and a bottom surface; a module attachment extending from the top surface; and a hook extending from the bottom surface along a lateral side of the main body. The hook of one of the M.2 fasteners is received through an attachment aperture of an adjustment position. The hook is pressed-fit over the top surface of the main body of another M.2 fastener. The hook secures the M.2 riser card between the pair of M.2 fasteners in a tool-less manner.

An electrical connection module and a power supply integration structure of a connection interface of the electrical connection module are disclosed. The electrical connection module includes a connection body and a terminal structure. The connection body has a jack communicating with the inside of the connection body for installing the terminal structure in the connection body to communicate with the jack. The terminal structure includes multiple terminals arranged in two rows. Each row has one or more power terminals. The power terminal in one row is defined as a positive pin, the power terminal of the other row is defined as a negative pin. An end of the power terminal in each row is electrically connected to a conductive part respectively. The electrical connection module is disposed across a power guide base, and the conductive part is in contact with the power guide base to for the power integration.

A connector gap between a module connector mating surface and the backplane connector of a chassis may be eliminated through a mechanism that forcefully pushes (or pulls) the module towards the backplane and/or forcefully pushes (or pulls) the backplane toward the module. A spring-loaded or resilient element may be used to fasten the module in a way that effectively fills any designed-in and tolerance-induced gap in the connector interface, allowing the connector to fully seat. In addition, a gasket or other compressible member may be included at the connector mating interface. The gap in the connector interface may be reduced by introducing adjustable card cage members that are capable of being set during the assembly or manufacturing process using special alignment fixtures. The gap in the connector interface may also be reduced by introducing a higher tolerance capable manufacturing process, such as machining, to the card cage sub-assembly.
