An adapter card with compression-attached memory modules that can be inserted into a conventional vertical connector enables use of CAMMs in systems with vertical memory module connectors. In one example, an adapter card or riser card includes a printed circuit board (PCB) having an edge to be received by a dual-inline memory module (DIMM) connector. First conductive contacts proximate to the edge of the PCB are to be received by the DIMM connector, enabling the first conductive contacts to couple with contacts of the DIMM connector. Second conductive contacts on a face of the PCB are to couple with a first compression attached memory module (CAMM) via a first compression mount technology (CMT) connector. The adapter card includes conductive traces on or in the PCB between the first conductive contacts and the second conductive contacts to couple the CAMM with the DIMM connector.

An apparatus is described. The apparatus includes a dual-in line memory module (DIMM) socket having a first electrical circuit component embedded in a latch of the DIMM socket. The first electrical circuit component has a first exposed electrical contact that is to contact or not contact a second exposed electrical contact of a second electrical circuit component that is embedded in a housing of the socket depending on whether a corner of a DIMM is or is not properly inserted into the DIMM socket.

Methods and apparatus for differential I/O (input/output) cards using compression mount technology (CMT) connectors. Assemblies include a CMT connector having an array of spring-loaded pins or contacts that are configured to contact respective CMT contact pads on a pair of printed circuit board (PCBs), such as an add-in card (AIC) and a motherboard. Stacked assemblies are also disclosed including multiple CMT AIC or PCIe modules communicatively coupled using on module CMT connectors. The connector solutions may be used for AICs without changing the overall PCB form factor outline of existing AICs employing edge connectors. Under a stacked assembly of multiple CMT PCIe modules interconnected by on module CMT connectors, wiring in the PCBs is configured to provide signaling supporting multi-lane PCIe or CXL links for each CMT PCIe module. The CMT connector approach also is scalable and can support more pins/contacts to facilitate additional I/O bandwidth.

An electrical receptacle connector includes a metallic shell, an outer shell, an insulated housing, and receptacle terminals. The receptacle terminals are held at the insulated housing. The metallic shell covers the insulated housing. The outer shell covers the metallic shell. The metallic shell has a reduced length to allow the exposure of the tongue portion. Elastic pieces of the outer shell extend toward the recessed holes of the metallic shell. When an electrical plug connector is mated with the electrical receptacle connector, the housing of the electrical plug connector contacts the elastic pieces of the electrical receptacle connector, so that the holding force between the electrical plug connector and the electrical receptacle connector can be increased. Hence, when the electrical plug connector is mated with the electrical receptacle connector, the high-frequency interference issue during signal transmission can be reduced.

A modular electronic device system includes an electronic device and a cover for the device that allows the device to be mechanically and electrically mounted to a stand or device adapter on the rear side of the cover. The cover or device adapter can be connectable to modularly attachable and removable accessory devices and can provide electrical ports for powering and operating the accessory devices. While mounted to a stand, power and data communications can be provided to the electronic device, cover, and accessory devices from the stand or an external source. The modular components of the system can be interchangeable to allow the system to be adapted to many different settings and use cases based on the types of components included as the accessory devices and based on the number of accessory devices used.

Technologies are generally described for multiple individual connectors in a single connector assembly. The individual connectors may be any form-fit suitable connectors such as USB type connectors and similar ones. The connector assembly may be circular, oval, rectangular, or other shapes. Coupling between the plug and receptacle of the connector assembly may be through threads, pressure, a click-on mechanism, screws, or other compatible mechanisms. Off-the-shelf individual connectors may be fitted with a module adaptor, then inserted into an accordingly shaped inside portion of the outer shell, and held in place through a latching mechanism or similar. Alternatively, the connector assembly may be formed with the individual connectors and cabling may be added subsequently. In some examples, post retention or backshell retention may be implemented in conjunction with the plug connectors.

An electric connecting device includes an insulator with a front end abutting surface and a rear end mounting surface, a terminal module and a USB plugging module in the insulator. A first plugging cavity and a second plugging cavity distributed in a horizontal direction and a guide hole between them are arranged in the insulator. The first plugging cavity and the second plugging cavity forwardly penetrate through the front end abutting surface and form a round interface and a USB interface respectively. By simultaneously providing the two plugging cavities on the insulator, two different plugging functions can be satisfied. The transmission of a DC power supply and the transmission of a USB signal are realized at the same time. The integrated structure can reduce the occupation of a circuit board space and the assembly cost of the product.

An apparatus may include (1) a terminal connector configured to be electrically coupled to a power interface of a computing device, (2) an inline terminal block assembly that is independent of the terminal connector, (3) at least one terminal-side power cable configured to be electrically coupled between the terminal connector and the inline terminal block assembly, and (4) at least one distribution-side power cable configured to be electrically coupled between the inline terminal block assembly and a power distribution system.

A z-axis compression connector includes a plurality of high-speed signal contacts arranged in a grid of M rows by N columns, and a plurality of signal return contacts arranged between the N columns. A first signal return contact is positioned mid-way in line between a first signal contact and a second signal contact, where the first signal contact is in a first row and a first column and the second signal contact is in the first row and a second column adjacent to the first column.

A system and method for providing electromagnetic compatibility (EMC) protection for a removable component through a retractable EMC protection apparatus. The EMC protection apparatus includes an actuation pin, a stabilizing bracket, an actuation arm, a spring brace, an arm spring, a second stabilizing bracket, a rounded pin, an angled engagement feature, an enclosure opening, a conductive surface, a protection device spring, and a retractable EMC protection device. The actuation pin is configured to engage upon a surface of an end product upon insertion of the removable component into the end product. The activation arm is configured to simultaneously compress the arm spring against the stop brace and to push on the angled engagement feature. The angled engagement feature is configured to push in a downward direction on the conductive surface to seal an enclosure opening of the removable component with the retractable EMC protection device.
