摘要:
A small, low-profile plug connector for use with electronic devices provides a latching member with a pair of hooks that engage mating holes in a guide frame, and which can be easily delatched from the guide frame or opposing connector or housing. The hooks lock the plug connector into engagement with the frame or housing, but are readily released by way of a simple ramp and lobe mechanism in the plug connector. The ramp and lobe mechanism converts horizontal movement of a pull tab-like actuator into vertical movement of a latching member such that the hooks are lifted upward and disengaged from the guide frame or housing.

A connector guide mounted in front of a receptacle connector is provided. The guide may include a press arm that helps urge a mating connector into a desired alignment. The guide is separate from the receptacle connector and serves to align contact surfaces and provide strain relief to the receptacle connector.

A shielded housing that provides a shield to a circuit board connector of the SFP-style includes a conductive body that encompasses the connector. The housing has an opening that defines an entrance of the housing through which an opposing mating connector may be inserted. The housing entrance includes one or more guide members that extend into the center of the housing and provide a guide for guiding an opposing mating connector into engagement with the circuit board connector.

A termination structure for mating a cable connector to a circuit board includes a plurality of associated sets of terminals, each terminal set including a pair of differential signal terminals and a ground reference terminal. Each associated set of terminals is arranged in triangular pattern through the connector in order to reduce the impedance through the connector, and the sets are fixed within modules or blocks that are engageable together to form a connector housing. The housing modules permit adjacent associated terminal sets to be easily inverted so that the ground reference terminals of alternating associated terminal sets are located along one row of the connector along with signal terminals of intervening terminal sets, while the ground reference terminals of intervening terminal sets are located along a second row of the connector, along with the signal terminals of alternating associated terminal sets.

An assembly for removably connecting data storage devices is provided for coupling a plurality of such devices within a computer or file server. The assembly comprises a plurality of trays each having a data storage device and a first electrical connector mounted thereto. Each tray contains an adapter assembly, having a second electrical connector, for consolidating the plurality of signals between the computer and the device. The trays are removably inserted within a housing having a plurality of printed circuit boards for connecting to the first electrical connectors of the inserted trays. A plurality of locking and actuating assemblies mounted within the housing govern insertion and removal of the trays into and out of the housing and passage of signals between the electrical connectors.

A personal computer includes a frame unit and a top cover mounted to pivot upward and outward to the rear of the system, or alternately, upward to the side. One or more DASD storage devices may be mounted to extend downward from the top cover. A planar board is attached atop the lower side of the frame unit, where flexible mounting hardware allows the attachment of one of several types of planar boards. A central support structure includes a riser card plugged into a connector of the planar board, and a number of card connectors into which option cards can be plugged for electrical connection with the planar board. The central support structure also includes a bracket extending along the rear of the computer, having slots through which port connectors of the option cards can extend. The central support structure is held in engagement with the connector of the planar board by the top cover when this cover is closed. When the top cover is open, the DASD storage devices may be easily replaced, the central support structure may be unplugged from the planar board, and the planar board can be easily replaced or serviced. A front surface of the computer includes a door, which is opened by rotation outward and downward, to be slid inward, providing access for the replacement of media in the storage devices. This door and the top cover are separately lockable using a multi-function lock.

An apparatus for loading BIOS stored on a direct access storage device in a personal computer system, the system comprising direct access storage device, and a processor card removably mounted to a planar board. The processor card comprises a system processor and ROM memory, while the planar board includes a main memory. A master boot record is stored on the direct access storage device. The master boot record contains a data segment and an executable code segment, the data segment representing the hardware configuration of the personal computer system. A first portion of BIOS included in the ROM memory initializes the system and causes loading of the master boot record into main memory. This first portion of BIOS further compares the hardware configuration data of the master boot record with the hardware configuration data in the ROM memory to verify compatibility with the system processor. Once compatibility of the master boot record with the system processor is verified, the first portion of BIOS transfers control to an executable code segment of the master boot record to effect loading of the remaining portion of BIOS into main memory, and the first portion of BIOS is discarded.

Cover assemblies, capable of being locked and unlocked by means of a key, are configured to be placed over the connectors at each end of an external computer system cable. When these cover assemblies are locked in place, the cable cannot be unplugged from the connector ports of the system devices. When these cover assemblies are unlocked, they can be removed from the cable, and the cable can then be unplugged from the connector ports.A first type of cover assembly is designed to operate with a connector which is fastened in place in its plugged position by means of a pair of screws, while a second type of cover assembly is designed to operate with a connector which is fastened in placed by means of a pair of rotatable wire bails. These cover assemblies may also be used to prevent access to connector ports to which cables are not attached by locking in place terminators commonly used on such ports, or by locking in place shells configured for this purpose, if such terminators are otherwise not required.

A connector guide mounted in front of a receptacle connector is provided with a latch that engages a connector mounted on a circuit board when a mating connector is inserted into the connector on the circuit board. The guide is separate from the plug connector and serves to align contact surfaces and provide strain relief to the receptacle connector.
