A memory card includes a packaging board and a plurality of contacts disposed on one side surface of the packaging board, where the contacts include a power supply contact, a grounding contact, and a detection contact. The detection contact is disposed adjacent to one of the power supply contact or the grounding contact and is suspended or electrically connected to the other of the power supply contact or the grounding contact.

The present disclosure provides an adaptor, comprising an adapting bracket, an adapting member, and at least one locking component. The adapting bracket comprises a chute comprising two opposite sidewalls and a bottom wall. The bottom wall is disposed between the two sidewalls. The adapting member is disposed on the adapting bracket. The adapting member comprises an adapting interface and is in communicating with the chute. The at least one locking component is disposed in the adapting bracket. Each of the locking components comprises a locking member movably extending into the chute. When an electronic component is inserted in the chute, a mating interface of the electronic component is connected to the adapting interface, and the locking member is inserted into an engaging groove of the electronic component. By protecting the electronic component with the adapting bracket, it is possible to avoid damage to the electronic component from impacts.

A tray inserted in an electronic device, and housing a card removable from the electronic device, the tray includes: a first interior wall partially defining a housing space housing the card; a second interior wall facing the first interior wall, and partially defining the housing space; and an elastic member provided to the second interior wall, wherein the elastic member is formed of rubber, and configured to change in shape in conformity with a shape of the card while the card is housed in the tray, and to apply to the card elastic force toward the first interior wall.

A circuit card assembly including a printed circuit board arranged to include one or more electronic circuits and a frame connected to the printed circuit board. The circuit card including at least one connector arranged to detachably engage with a backplane connector of the electronic chassis to establish an electrical connection with a backplane printed wiring board (PWB) of the electronic chassis. The circuit card also including a front panel having at least one input/output connector and an EMI/RFI gasket positioned along a perimeter of the back side of the front panel where the EMI/RFI gasket is arranged to contact a surface of the electronic chassis along a perimeter of the circuit card assembly slot when the circuit card assembly is extended into the circuit card assembly slot.

A mouse capable of receiving a stylus pen, characterized in that: a housing space capable of receiving a stylus pen is provided in the mouse, where the housing space forms an opening at a side of the mouse, and the stylus pen is placed inside the opening and is fixed in the housing space. An objective of the present invention is to provide a mouse capable of receiving a stylus pen, to store the stylus pen into the mouse, so as to reduce space occupied by peripheral devices and avoid making a working environment in a mess.

Disclosed are an electronic device, an expansion card assembly and a server device. The electronic device comprises a hard disk slot and the expansion card assembly. The expansion card assembly is arranged in the hard disk slot in a pluggable manner; the hard disk slot comprises a first type of interface and a second type of interface. The first type of interface is used for communicating with the hard disk, and the second type of interface is used for communicating with the expansion card assembly. Therefore, the expansion card assembly is expanded by means of the hard disk slot in the electronic device, so that the expansion requirement of the expansion card assembly is met.

A waterproof card holder includes a card holder frame and a cover plate located at top of the card holder frame. The waterproof card holder includes a sleeve integrated with and extending from an inner side of the cover plate and a through-hole penetrating through the sleeve and the cover plate. A waterproof mechanism is accommodated in the sleeve. The waterproof mechanism includes a main body, a first end portion located inside the sleeve, a second end portion protruding from the sleeve, and a waterproof ring located on a periphery of the main body and close to the first end portion. The waterproof ring and the sleeve form a sliding sealing structure therebetween.

A connector is mountable on a circuit board. A card-type device is accommodatable in the connector. The connector comprises a base, a cover and a terminal. The cover is attached to the base to be openable and closable. The terminal is held by the base. The cover has one or more connection portions. The connection portion is directly connected to the circuit board under a close state where the connector is mounted on the circuit board and the cover is closed relative to the base.

A connector is provided with a base, a terminal, a cover and a heat conductive member. The base has a holding portion, and the terminal is held by the holding portion. The cover is provided with a main portion having an inner surface and an outer surface. The heat conductive member is fixed on the inner surface. When the connector is connected to a card-type device, the terminal pushes a card-type device against the heat conductive member in a predetermined direction perpendicular to a circuit board. When the connector is connected to the card-type device, an interval between the main portion and the holding portion is kept constant in the predetermined direction.

An electric apparatus includes a substrate having a ground pattern on a top surface of the substrate; a conductive housing on the ground pattern and having an insertion space; a conductive connector disposed between the ground pattern and the conductive housing and connected to the ground pattern and the conductive housing, wherein the conductive housing is fixed to the substrate via the conductive connector; and a conductive cover coupled to the conductive housing, wherein the conductive cover is configured to move from a first position, at which the conductive cover externally opens the insertion space, to a second position, at which the conductive cover closes the insertion space.
