The support hardware has a side rail extending between the first and second mounting blocks. A cavity that receives the card edge connector is defined on a first side by the side rail and on first and second ends by the first and second mounting blocks. The top of the support hardware is flush with or below the top of the card edge connector.

In some examples, a socket locking system can comprise a socket; a printed circuit board (PCB) card disposed in the socket; a first locking handle and a second locking handle to lock the PCB card in the socket; and a PCB retention band including: an elongated closed loop forming a first distal end and a second distal end opposite from the first distal end, wherein the first distal end is to contact the first locking handle and the second distal end is to contact the second locking handle; and a retention portion coupled to the elongated closed loop of material to contact a top surface of the PCB card to disposition the PCB card in the socket.

A fluid ejection device, in an example, that includes a housing with the housing including a plurality of lateral hooks to engage with a plurality of posts of a connector, the lateral hooks running, at least partially, parallel to a cable receiving surface wherein a portion of a printed circuit board (PCB) comprising electrical interconnects extends beyond the cable receiving surface to interface with the connector.

A card edge connector includes an elongated insulative housing, a number of terminals retained to the housing, and a metallic member formed integrally with the housing via an insert-molding process. The housing includes two lengthwise walls, a central slot defining by the two lengthwise walls, and two protrusions located at two opposite ends of the two lengthwise walls. The protrusions protrude upwardly out of an upper surface of the lengthwise walls. The metallic member includes two main portions retained respectively in the two lengthwise walls and a pair of connecting portions connecting therebetween. The connecting portions are located at the bottom of the metallic member.

A card edge connector includes an insulative elongated housing, a plurality of contacts disposed in the housing, and a pair of rotatable ejectors at two ends of the housing. The housing includes a pair of side walls extending along the longitudinal direction with a receiving slot therebetween in a transverse direction perpendicular to the longitudinal direction, and a pair of towers at two opposite ends of the housing in the longitudinal direction. The receiving slot is configured to receive a card type memory module. The pair of ejectors are disposed in the corresponding towers, respectively. Each ejector includes a kicker at the bottom wherein a tip of the kicker will not invade into the space between the pair of outermost contacts so as not interfere with the corresponding outermost contacts when the ejector is rotated to be at an open/ejecting position.

An edge card mounting structure includes an edge card, an electrical connector disposed on a circuit board, and a rack that holds the edge card and is inserted into the electrical connector to electrically connect the edge card to the electrical connector. The rack includes a rack body that accommodates the edge card, two bearing plates bilaterally disposed in the rack body, and two adjustment members that are elastically pressable to move the accommodated edge card downwardly into abutment against the bearing plates where the electric contacts of the edge card are kept in contact with the respective contact endpieces of the conducting terminal set of the electrical connector for transmitting high frequency signals.

A card edge connector assembly includes a card edge connector having a housing defining a card slot receiving a paddle card of a pluggable module having a base mounted to a host circuit board holding contacts in the card slot to electrically connect to the paddle card. Support hardware is coupled to the housing having a base including a cavity receiving the card edge connector and a support beam extending from the base having a pocket receiving the pluggable module. The support beam has a support surface configured to support the pluggable module independent of the card edge connector. The support hardware has a latch coupled to the support beam latchably coupled to the pluggable module to secure the pluggable module in the support hardware electrically coupled to the card edge connector.

Embodiments are directed towards apparatuses, methods, and systems for a connector having a housing body to couple a dual in-line memory module (DIMM) to a printed circuit board (PCB). In embodiments, the housing body includes first and second opposing ends of the connector and a first and a second latch coupled at the respective first and second opposing ends of the connector to engage the DIMM. In embodiments, the first and the second opposing ends have respective first and second heights relative to a height of the housing body to allow the DIMM to be inserted or removed at an angle when disengaged from the first and second latch. In embodiments, one or more of the latches are removably coupled to the connector and/or can be rotated into a lay-flat position to allow the DIMM to be removed at an angle. Additional embodiments may be described and claimed.

An electrical connector and method for connecting an electrical conductor to a board, especially to a circuit board, includes a housing which can be electrically connected on a connecting side of the electrical connector to an electrical connecting member or conductor. The housing includes on a contact side of the electrical connector one or more contacts in order to make electrical contact with one or more mating contacts of the circuit board. A locking pin assembly passes through an opening of the circuit board when the connector is mounted on the board and can move from a retracted release position to an expanded locking position in which its diameter on the side of the opening facing away from the housing is larger than the diameter of the opening of the circuit board. The housing includes at least one actuation device which moves relative to the housing. The locking pin assembly includes at least two functional elements able to move relative to each other.
