Abstract: A card connection adaptor is provided which is used for connecting, to a connector of a card slot compliant with a first standard, a card compliant with a second standard. The adaptor includes: a first connector compliant with the first standard and adapted to be electrically connected to the connector of the card slot; a second connector compliant with the second standard; and signal conversion circuitry for performing signal conversion between a first-standard-compliant signal and a second-standard-compliant signal. A card retaining space for retaining the second-standard-compliant card inserted therein is formed in a housing which holds the first connector, the second connector and the signal conversion circuit. The card retaining space has a card insertion port which opens generally perpendicularly to an insertion direction in which the card connection adaptor is inserted into the card slot.

Abstract: A connector for module that connects a module to a printed circuit board in a position wherein the board plane of the module is approximately parallel to the printed circuit board.

Abstract: A connector of the present invention is provided with a ventilation means that permits air to pass through along an electronic module with respect to a housing means holding said electronic module. The housing means includes a main body mounting thereon contacts to be connected with conductive pads provided at a front end of the electronic module and a pair of arms, projected from opposite ends of the main body, to hold the electronic module at opposite ends thereof. The ventilation means is provided at the main body and/or the pair of arms. The ventilation means thus formed can permit the electronic module to be cooled efficiently.

Abstract: In an electrical connector of the present invention, a cover is mounted on a main body in such a manner as to be rotatable around a shaft and is rotatably connected with a slider at a position thereof shifted from the shaft. A connection object, e. g., memory module, is detachable supported by the slider. When the cover is rotated, the slider is moved reciprocally with respect to contacts arranged in the main body in association with the rotation of the cover, so that the memory module can be connected with the contacts. By virtue of this, the loading or unloading of the memory module can be simplified and also the connector or the memory module can be prevented from being damaged or deformed during the operation.

Abstract: A cap that is to be fitted to a printed circuit board, which has a conductive pad on the front side of the rectangular board thereof and which is to be connected to the connector. The cap is formed into a bag and is shaped into a wedge that gets thinner towards the front, and the cap has a window for exposing the conductive pad of the printed circuit board.
