Abstract: A back plate configured to support a circuit board includes a body. The body defines a central recess formed into a top surface thereof, and a raised main support column extending from the central recess and adapted to support the circuit board.

Abstract: An electronic apparatus includes a main circuit board, an electronic device, side circuit boards, and a pressure applying unit. The electronic device is installed on and electrically connected to the main circuit board. The side circuit boards are positioned at edges of the electronic device on a side of the electronic device away from the main circuit board and electrically connected to the electronic device. The pressure applying unit is positioned on a side of the electronic device and on each of the side circuit boards away from the main circuit board. The pressure applying unit applies pressure: 1) to the side circuit boards to maintain an electrical connection between the side circuit boards and the electronic device; and 2) to side regions of the electronic device to maintain an electrical connection between the main circuit board and the electronic device.

Abstract: An electrical connector includes an insulated shell having a slot in a side wall extending longitudinally, a conductive assembly, and a support member embedded in the slot. The conductive assembly includes a conductive shell assembled on the insulated shell, a plurality of contact terminals each having a base and an electrical contact segment extending from the base, and a base plate detachably connected to the insulated shell. A base of each of the contact terminals is fixed to the base plate. The conductive shell and the electrical contact segment of each of the contact terminals are held in electrical contact with each other by the base plate. A pair of free ends of the support member are fixed in the slot.

Abstract: A circuit board assembly includes a chip, a first loading board, a circuit board, an intermediate board and a second loading board. The first loading board is arranged on the chip, and the circuit board is electrically connected to the chip. The intermediate board is arranged on the circuit board and positions the chip. The second loading board is arranged on a side of the circuit board opposite the intermediate board. The second loading board includes a plurality of protrusions and indentations formed on a first side thereof opposing the circuit board.

Abstract: A loading assembly includes a base plate configured to support a circuit board placed thereon, a pressing plate configured to press an electrical member on the circuit board, and a first connection assembly connecting the pressing plate to the base plate and pressing the electrical member on the circuit board through the pressing plate. The first connection assembly includes a first nut fixed on the base plate, a first bolt passing through the pressing plate and screwed to the first nut, and a first spring sleeved on the first bolt and compressed between a head of the first bolt and the pressing plate. A first locking part is formed on the first bolt. The first locking part is pressed against an end face of the first nut when the first bolt is screwed to an installation position to prevent the first bolt from being rotated relative to the first nut.
