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.

A connector includes two insulators which hold contacts connected to lead wires and are arranged on two surfaces of a base end portion of a ceramic element, two spring components which have flat plate portions located on respective outer surfaces of the two insulators and spring portions supported by the flat plate portions, and a cylindrical sleeve. Each spring portion has an inclined surface which inclines in a movement direction in which the sleeve moves toward the spring components. Each spring portion is elastically deformed by the sleeve hanging over the spring portion. The two insulators hold the base end portion from two sides by being pushed by the flat plate portions in directions in which the two insulators are brought closer to each other. The contacts are pushed against the terminal electrodes.

A cat teaser includes a base, pogo pins of a power supply, a main body shell, a fixed frame, a main control circuit board, a main body motor, a laser emitting module, an auxiliary motor that swings up and down, and a conductive disc. The pogo pins of the power supply are in contact with the conductive disc. The conductive disc supplies power to the main control circuit board. The main control circuit board controls the main body motor, the laser emitting module and the auxiliary motor that swings up and down.

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.

A connector comprises a pair of terminals for clamping and electrically connecting to a first conductive member. A first terminal includes a plurality of first elastic arms arranged in a row, with each first elastic arm having a first contact and a third contact formed thereon. The second terminal is laminated on an outer side of the first terminal and includes a plurality of second elastic arms arranged in a row. Each second elastic arm includes a second contact formed thereon. Each second contact protrudes to an inner side of the first elastic arms from a gap between two adjacent first elastic arms. The plurality of second elastic arms respectively abut against the outer sides of the plurality of first elastic arms. The first contact, the second contact and the third contact are adapted to be in electrical contact with the inserted first conductive member simultaneously.
