A method and latch for use with mounting a panel mount module to a panel. The latch includes a housing with a module receiving cavity. The module receiving cavity has cavity walls with projections extending from the cavity walls into the module receiving cavity. The projections are configured to be positioned in openings provided in side walls of the module when the latch is mounted on the module. Securing openings extend through the housing. Mounting hardware is positioned in the securing openings. The securing openings and mounting hardware are configured to be positioned in line with mounting openings in the panel. With the mounting hardware properly secured in the mounting openings of the panel and the projections properly secured in the openings of the module, the module is prevented from movement relative to the panel and any forces applied to the module will be transferred through the latch to the panel.

An electronic device having a detachable memory is provided with a docking connector, and includes a device body and a memory. The device body has an accommodating slot and a stopping portion provided corresponding to the accommodating slot, and the stopping portion and the accommodating slot jointly form a displacement space in between. The memory is provided with a connector and a protruding stopped portion. When the memory is accommodated in the accommodating slot, the stopped portion is moved along into the displacement space and is stopped by the stopping portion, and the connector is docked with the docking connector. Thus, the memory is provided with an anti-misplugging effect.

An electronic apparatus including a housing, an electronic component unit main body, an engagement lever, and an engaged member, in which the engagement lever includes a lever main body, an engagement groove, and a restricting member, the lever main body is displaceable between a first state in which the one end portion is inclined to protrude rearward with respect to the other end portion in an insertion direction of the electronic component unit main body with respect to the accommodating part and the engagement groove abuts against the engaged member from the rear in the insertion direction, and a second state in which the lever main body is vertical from the one end portion to the other end portion and the engagement groove engages with the engaged member, and the restricting member is able to restrict the lever main body to being in the second state.

The invention provides a motherboard assembly. The motherboard assembly includes a circuit board, an expansion card connector, an expansion card assembly, a bracket and a fastener. The expansion card connector is disposed on the circuit board. The expansion card assembly includes a cage, an adapter card, and at least one expansion card. The adapter card is installed on the cage and includes an electrical connector. The electrical connector is inserted into the expansion card connector, and the expansion card is installed on the adapter card. The bracket includes a first mount plate and a second mount plate connected to each other. The first mount plate is fixed on the circuit board, and the second mount plate is located farther away from the circuit board than the first mount plate. The fastener is disposed through the cage and screwed into the second mount plate of the bracket.

Locking structure includes a first connector, a second connector, a locking member, a sliding member, and a holding member. The first connector includes a first cavity and a first protrusion in the first cavity. The second connector includes a second cavity and a second protrusion in the second cavity. The locking member is slidably received in the second cavity and extends into the first cavity. A peripheral wall of the locking member defines a fastening groove. The sliding member extends into the second cavity and abuts the locking member to drive the locking member to move toward the first protrusion and the second protrusion so that two opposite side walls of the fastening groove press against opposite sides of the first protrusion and the second protrusion. The sliding member defines a latching slot. The holding member includes a latching member for latching in or disengaging from the latching slot.

A hook fixing mechanism includes a fixing frame, a first hook, and a second hook. The first hook is rotationally mounted on the fixing frame. A first end of the first hook protrudes from the fixing frame, and a second end of the first hook is movably snapped on the fixing frame. The second hook is rotationally mounted on the fixing frame. A third end of the second hook protrudes from the fixing frame, and a fourth end of the second hook resists against the first hook.

A server chassis, configured to detachably fasten a PCB, includes a case, an expansion frame, and a fastening assembly. The fastening assembly includes a slidable component, a guiding component disposed through the slidable component and fixed to the case, a movable pin movably disposed through the slidable component, and a fastening pin fixed to the slidable component. When the slidable component is at a fastening position, the movable pin is movable between inserted and extracted positions. When the movable pin is at the inserted position, the movable pin is disposed through the slidable component and the case, such that the slidable component is positioned at the fastening position, and the fastening pin is disposed through the PCB and the expansion frame. When the movable pin is at the extracted position, the movable pin is disengaged from the case, such that the slidable component is slidable to a releasing position.

An electronic component assembly includes a board having an electronic component, a connector mounted to the board and electrically connected to the electronic component and having an anchoring feature positioned on an exterior of the connector, and a card having another electronic component and a securing feature. The electronic component assembly also includes a movable member positioned on one of the connector or the card. The movable member is positioned in the securing feature and contacts the anchoring feature to secure the card in a seated position in the connector, or the anchoring feature includes the movable member and contacts the securing feature to secure the card in the seated position in the connector.

An insertion tool for assisting in the insertion of an OCP 3.0 type expansion card in an expansion card slot of a computer system is disclosed. The expansion card may be a pull tab type form factor that does not have a mechanism such as an ejector latch to assist in applying force to insert the card. The expansion card has a front panel opposite a distal edge connector. The tool has a handle and a head coupled to the handle. The head has two contact areas that contact different areas of the front panel of the expansion card. For example, one of the contact areas may be an extended side arm and the other area may be a lateral rib extending from the head.
