A modular die cast enclosure comprising a top section with a top mid-plane and a bottom section with a bottom mid-plane and an internal bottom cover. The bottom section having one or more of a first type of connectors. The top section having one or more of a second type of connectors on. The internal bottom cover having one or more of a third type of connectors. Wherein said first type of connectors couple with said second type of connectors when the top section is placed on the bottom section and allow to electrically connect said top and bottom sections via said third type of connectors.

Examples of card fasteners and assemblies for fastening cards to printed circuit boards are discussed. A card fastener comprises a frame comprising a first arm, a second arm, and an intermediate portion joining the first arm and the second arm. A compressive pad is attached to the intermediate portion. The first arm and second arm are to couple to hooks on a printed circuit board of a device and the compressive pad is to come in contact with the card.

A cable connector assembly includes a contact holder holding first and second contacts in contact channels terminated to ends of conductors of a cable. The contacts have mating ends forward of the front of the contact holder. The cable connector assembly includes a contact shield coupled to the contact holder having a base and a shroud. The base surrounds a base chamber that receives an end of the cable and the contact holder and provides electrical shielding at first and second interfaces. The shroud surrounds a shroud chamber that receives the mating ends of the first and second contacts to provide electrical shielding along the mating ends of the first and second contacts.

A memory module testing system operating in a vibratory environment can retain a memory module in place in a memory socket using both socket latches and a retainer clip. The retainer clip can attach to a module support tower of the memory socket. The retainer clip can have a flexible multi-spring structure forming a three-axis vibration dampening system that can prevent the socket latches from opening while testing in the test environment. The retainer clip can secure the socket latches using an upper flange and a lower flange to prevent unintended motion of the socket latches. The retainer clip can be secured to the module support towers at the ends of the memory socket using clip arms and clip arm tips to attach to the module support towers.

A connector with a tolerance module includes a socket and a plug adapted to the socket, wherein the socket includes a first housing, the plug includes a tolerance module and a third housing, the tolerance module includes a second housing, the second housing includes second contact members, the second housing is movably arranged on the third housing in a direction perpendicular to the axial direction of the connector, and the second contact members are floatingly assembled in the second housing to enable displacement in the direction perpendicular to the axial direction of the connector. The second housing only generates translational motion without displacement when the connector is inserted. The tolerance of the plug and the socket is realized by the floating assembly of the second contact members in the second housing.

A printed circuit (PC) card apparatus can, in an absence of external power provided to a Peripheral Component Interconnect Express (PCIe) PC card, prevent and detect unauthorized access to secure data stored on a memory device mounted on the PCIe PC card. The PCIe card includes a primary battery to supply, when external power is disconnected from the PCIe card, power to an electronic security device mounted on the PCIe card. The PC card apparatus also includes a PCIe edge connector protector enclosing electrically conductive fingers of a PCIe edge card connector. The PCIe edge connector protector includes a hidden supplemental charge storage device integrated into the PCIe edge connector protector. The PCIe edge connector protector also includes electrically conductive contacts to transfer supplemental power from the supplemental charge storage device to the electronic security device.

Auxiliary power connector PCBs are described. In one example, an auxiliary power connector is described. The auxiliary power connector includes a printed circuit board (PCB) and a PCI express graphics (PEG) connector mounted to the PCB, the PEG connector configured to connect to an auxiliary power source. The auxiliary power connector further includes a set of connectors provided on the PCB, the set of connectors configured to connect the PCB to a main PCB of a device.

A connection strip is designed as a printed circuit board connector and has a strip-like connection housing, which is formed in one part or in a plurality of parts. The connection housing has a plurality of outer sides, the first outer side having a mating face side on which there are at least two or more mating face plug-in contacts, which can each be plugged together with a corresponding plug-in contact of a corresponding plug connector. The connection housing is further designed to have printed circuit board plug-in contacts on one, two or three of the other outer sides, which contacts project beyond the respective outer side so that on the one or more outer sides on which the printed circuit board plug-in contacts are provided, a printed circuit board can be soldered. A method for manufacturing the connection strip is also provided.
