The present invention relates to a gap supporter for a printed circuit board, and a package including a gap supporter for a printed circuit board and an insulation sheet coupled thereto. A gap supporter for a printed circuit board includes a fixed body part which has a metal thin-film formed on the surface of the lower end thereof, and is fixed to one surface of the printed circuit board by soldering of the metal thin-film; a clamping groove formed in a groove shape on the fixed body part, and having an insulation sheet inserted and clamped thereto to protect an element on one surface of the printed circuit board; and an anti-separation part formed on the other end of the fixed body part so as to be defined by the clamping groove, so as to fix the insulation sheet and prevent the insulation sheet from being separated.

An integrated stand-off for a printed circuit board (PCB), and methods of making the integrated stand-off, and mounting such integrated stand-off to the PCB are disclosed. The integrated stand-off includes a metal grounding contact and a plastic element. The metal grounding contact is stamped on a first surface of a sheet metal chassis and the plastic element is overmolded on the metal grounded contact. The metal grounding contact is completely encased within the plastic element to distance the sheet metal chassis from contacting the PCB for preventing electrical shorts there between.

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.

The present invention relates to a gap supporter for a printed circuit board, and a package including a gap supporter for a printed circuit board and an insulation sheet coupled thereto. A gap supporter for a printed circuit board includes a fixed body part which has a metal thin-film formed on the surface of the lower end thereof, and is fixed to one surface of the printed circuit board by soldering of the metal thin-film; a clamping groove formed in a groove shape on the fixed body part, and having an insulation sheet inserted and clamped thereto to protect an element on one surface of the printed circuit board; and an anti-separation part formed on the other end of the fixed body part so as to be defined by the clamping groove, so as to fix the insulation sheet and prevent the insulation sheet from being separated.

A fastener includes a base having a joint plate extended therefrom toward a first direction, a joint plate extended from the joint plate toward a second direction and configured to secure to an electronic base board, and a fastening member protruded thereon toward a third direction. The fastener includes an elastic compressive unit connected to the joint plate and including a pushing part configured to abut with a circuit board downwardly rotated. Subject to the stress in the first direction and applied by the circuit board, the pushing part is moved back and the elastically-compressive unit is compressed to make the circuit board rotate to the bottom side of the pushing part, and an edge of the circuit board can be inserted into and abutted thereon the fastening member, and the circuit board is accommodated in a fastening space formed on the outside of the fastening member.

A supporting member includes a body portion, at least one first fixing portion, and at least one second fixing portion. The first fixing portion is connected to a side of the body portion and bends relative to the body portion. The first fixing portion is configured to be fixed to a first circuit board. The second fixing portion is connected to another side of the body portion and bends relative to the body portion. The second fixing portion is configured to be fixed to a second circuit board.

Embodiments of the present application relate to a power supply device, including a housing, a circuit board and a connecting assembly. The housing defines an accommodation space, and includes: a housing positioning component, a first opening, and a second opening. The housing positioning component is disposed in the accommodation space. The circuit board is disposed in the accommodation space, and includes: a circuit board positioning component, a power input port, and a power output port. The power input port is disposed corresponding to the first opening. The power output port is disposed corresponding to the second opening, and electrically connected to the power output port.
