A configurable modular computer enclosure includes a plurality of outer enclosures (1, 2, 3), the outer enclosures being connected together in a depth stacked formation producing a single composite outer enclosure with a single internal volume and a depth equalling the combined depths of the outer enclosures. The composite outer enclosure houses multiple sets of configurable inner enclosures (4, 5, 6, 7, 8), each inner enclosure set being formed into a composite inner enclosure by connecting together the inner enclosures in the set, allowing unlimited configurations of composite inner enclosures. Each composite inner enclosure is inserted into the composite outer enclosure and aligned via guides or runners (9) integrated into the outer enclosures.

A system and method includes stacking a first network node and a second network node on each other, making a surface contact between the network nodes using a first surface connector disposed on an upper surface of a first chassis of the first network node and a second surface connector on a lower surface of the second network node, directly connecting one of the first network node and the second network node to a computer network, and controlling another of the first network node and the second network node to connect the computer network through the surface contact made using the first surface connector and the second surface connector.

An expandable electronics storage chassis includes a base electronics storage tray and an expansion electronics storage tray. The base electronics storage tray has a first end and a second end. The first end includes a first base edge and a first pair of side edges that define a first opening. The expansion electronics storage tray has a third end and a fourth end. The third end includes a second base edge and a second pair of side edges that define a second opening. The fourth end includes a third base edge and a third pair of side edges that define a third opening. When assembled, the second end of the expansion electronics storage tray overlaps and is coupleable to the first end of the base electronics storage tray.

A lottery ticket dispenser array includes a plurality of separate bins, each bin having a housing with a back side. A circuit board fixed to the back side of the housing to supply power and control functions to the bin. The circuit boards of adjacent bins are rigidly interconnected via complimentary electronic connectors. At each bin, the circuit board is mounted to the back side of the housing with a defined relative degree of movement between the circuit board and the housing in at least a first direction. The rigidly interconnected circuit boards define a rigid structure and one or more of the bins are movable relative to the rigid structure such that the array absorbs misalignment, movement, and size variations between the bins without disconnection of the electronic connectors between the bins.

A device comprises a riser board and a riser bracket. The riser board has a connector that receives an expansion card. The riser bracket is coupled to the riser board, and includes a body portion and a latch. The body portion is coupled to the riser board such that the body portion is spaced apart from the riser board connector. The latch is rotatably coupled to the body portion, and rotates between a first position and a second position. When the latch is in the first position and the expansion card is received by the riser board connector, the expansion card is removable from the riser board connector. When the latch is in the second position and the expansion card is received by the riser board connector, the latch engages the expansion card such that the expansion card is not removable from the riser board connector.

A control device includes a casing and a control circuit substrate arranged inside the casing. The control circuit substrate includes: a control circuit mounted on the control circuit substrate; an internal connector connectable to a communication cable inside the casing, the communication cable being connected to an expansion circuit substrate; and an external connector connectable to another communication cable outside the casing, the another communication cable being connected to another expansion circuit substrate. The control circuit is connected to the internal connector and the external connector in parallel.

A communication system includes a first circuit card assembly having a first PCB and a first electrical connector with first contacts and a second circuit card assembly having a second PCB and a second electrical connector with second contacts. At least one of the PCBs include a slot configured to receive the other PCB when mated in a board mating direction. The first electrical connector is mated to the second electrical connector in a connector mating direction perpendicular to the board mating direction. The first contacts are mated to the second contacts in a contact mating direction as the first PCB and the second PCB are mated in the board mating direction and as the first electrical connector and the second electrical connector are mated in the connector mating direction. The contact mating direction is non-parallel to the board mating axis and non-parallel to the connector mating axis.

A frame structure for a cabinet enclosure has a front frame assembly having first and second front pillars, a rear frame assembly having first and second rear pillars, a first side brace member, and a second side brace member, each having a beam that has opposite ends, with the opposite ends of each side brace member connected to one of the front pillars and one of the rear pillars.

A substrate unit includes a first connector including a first terminal and a first housing accommodating the first terminal, and to be connected to an external connector, a first substrate on which the first connector is mounted, a second connector including a second terminal and a second housing accommodating the second terminal, and to be connected to the external connector, a second substrate on which the second connector is mounted and a case accommodating the first substrate and the second substrate. The first housing is provided with a first locking portion. The second housing is provided with a second locking portion. The first locking portion and the second locking portion are locked to each other. The first terminal and the second terminal are disposed to face an opening provided in the case through which the external connector is to be connected to the first connector and the second connector.
