An interface system for functional module and a functional module thereof are provided. The interface system for the functional module includes a main system and a plurality of functional modules. The main system has a mother board. Each of the functional modules has a circuit board, and at least one functional element disposed on the circuit board, and the functional element is an element having various functions and specifications. An expansion assembly is disposed between the mother board of the main system and the circuit board of any of the functional modules, and the expansion assembly is also disposed between the circuit boards of the functional modules. The main system is selectively and electrically connected to the functional modules through each of the expansion assemblies to be connected extendedly.

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.

An apparatus is described. The apparatus includes a DIMM socket having a seating floor that is to meet both longer length contacts and shorter length contacts of a DIMM when the DIMM is fully seated in the socket.

A printed circuit board enclosure employs a box having an open base and opposing side plates. Securing tabs extend laterally from the side plates. The securing tabs have bottom surfaces that are coplanar extensions of a bottom surface of the box and are configured to be attached to the main circuit board. A cover is received on the box. The cover is configured to close the open top of the box. The cover has side flanges extending downwardly from a top plate with mating tabs extending laterally from the side flanges aligned with the securing tabs.

A board connector used in a printed circuit board assembly and includes a shell, a pin and an elastic member. The shell has a chamber therein and a hole on a surface thereof. The pin is configured to accommodate in the chamber, wherein at least one part of the pin protrudes out of the shell via the hole. The elastic member is configured to locate in the chamber. The pin is located between the surface of the shell and the elastic member.

A system and a method for connecting at least one electronic card to an electronic board of a computer device, the system comprising an electronic board, equipped with a plurality of connectors for connecting at least one electronic cards to the electronic board, and slots for connecting at least one component to the electronic board. The at least one electronic card are substantially perpendicular to the electronic board. The system further comprises a first supporting means being configured such that the at least one electronic card is first mounted onto the first supporting means before the first supporting means is placed above the electronic board in the vertical direction. The system further comprises a second supporting means installed underneath the electronic board in the vertical direction. The system comprises further ejection mechanism and insertion mechanism. The system for connecting may comprise a plurality of electronic boards.

A flexible modularized system is configured to support graphics processing unit (GPU) cards of different dimensions. The system includes a riser bracket with attachment features for being coupled to a printed circuit board (PCB). The system further includes a fixing plate that is coupled to the riser bracket and which includes a plurality of adjustable holes. The system also includes a moving plate that is adjustably coupled to the fixing plate. The moving plate is movable between a plurality of positions. The moving plate has a first end that includes at least one latch, which engages the first adjustable hole in a first position and the second adjustable hole in a second position. The moving plate has a second end that is configured to secure in place one of the GPU cards relative to the PCB.

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.

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 printed circuit board enclosure employs a box having an open base and opposing side plates. Securing tabs extend laterally from the side plates. The securing tabs have bottom surfaces that are coplanar extensions of a bottom surface of the box and are configured to be attached to the main circuit board. A cover is received on the box. The cover is configured to close the open top of the box. The cover has side flanges extending downwardly from a top plate with mating tabs extending laterally from the side flanges aligned with the securing tabs.
