A memory socket includes a frame having a base portion and a side portion, and a push-eject locking mechanism in physical communication with the base portion and with the side portion. The push-eject locking mechanism to transition between an unlocked position and a locked position. The push-eject locking mechanism includes an eject bar component and a lever component. The weight of the eject bar component biases the push-eject locking mechanism towards the unlocked position. Based on a force being exerted on the lever component, the lever component pivots and transition the push-eject locking mechanism from the unlocked position to the locked position.

There may be provided a fastener arrangement. The fastener arrangement may include a first fastener tape including a first plurality of electrically conductive coupling elements and a first plurality of non-electrically conductive coupling elements. The fastener arrangement may further include a second fastener tape comprising a second plurality of electrically conductive coupling elements and a second plurality of non-electrically conductive coupling element. The fastener arrangement may further include a slider couplable to the first fastener tape and the second fastener tape for reversibly interleaving and interlocking the first plurality of electrically conductive and non-electrically conductive coupling elements with their corresponding second plurality of electrically conductive and non-electrically conductive elements. The interleaved and interlocked first and second plurality of electrically conductive coupling elements may form a plurality of conductive-bridges and the interleaved and interlocked first and second plurality of non-electrically conductive coupling elements may form a plurality of insulation-bridges.

An electrical connector system includes a circuit card assembly and a pluggable module. The circuit card assembly including a host circuit board, a socket connector mounted to the host circuit board, and a guide rail extending along the host circuit board. The socket connector has a socket substrate having upper contacts having mating interfaces being accessible from above the socket connector and being coplanar. The guide rail has a guide feature and a module actuator. The pluggable module includes a module body operatively engaging the guide rail to guide mating of the module body with the guide rail in a module mating direction. The pluggable module includes an actuation feature engaging the module actuator to force mating of module contacts with the upper contacts in a contact mating direction transverse to the module mating direction.

A circuit board assembly and an electronic device. The circuit board assembly includes: a circuit board to which a first board-to-board connector and a second board-to-board connector are mounted; a first bracket, where the first bracket is mounted on the circuit board, the first bracket is located on a side of the first board-to-board connector away from the circuit board; a second bracket, where the second bracket is mounted on the circuit board, and the second bracket is located on a side of the second board-to-board connector away from the circuit board, and the second bracket is disposed neighboring to the first bracket and the second bracket is provided with a tongue insert; and a fixing member, where the fixing member is connected to the circuit board and the fixing member is provided with a slot.

A shell grounding structure of electrical connector includes: a board-end connector including a housing with a docking space, conductive terminals pierced on both sides of the docking space, and a metal shell assembled on the housing; and a wire-end connector including a holder base with a bottom inserting portion combined with the docking space, contact terminals piercing the inserting portion in contact with the respective conductive terminals and connected with respective electrical cables, and a shielding shell having a cable opening for the cables to be exposed and a hooking plate provided with resisting elastic pieces extending toward the metal shell and forming contact.
