Abstract
A circuit board includes a first locking mechanism configured to secure the circuit board to a chassis. The circuit board also includes a connector disposed at an inboard end of the circuit board. The connector is configured to be electrically connected to a mating connector on either a backplane or a circuit board. The circuit board also includes a second locking mechanism. The second locking mechanism is configured to secure the connector of the circuit board to the mating connector of the backplane or the circuit card.
Claims20
A circuit board comprising:
- a first locking mechanism configured to secure the circuit board to a chassis;
- a connector disposed at an inboard end of the circuit board, the connector being configured to be electrically connected to a mating connector on one of a backplane or circuit card;
- and
- a second locking mechanism disposed at the inboard end of the circuit board, the second locking mechanism being configured to secure the connector of the circuit board to the mating connector of the one of the backplane or circuit card,
- wherein the second locking mechanism includes a threaded receptacle for receiving one of a threaded fastener or a captive threaded fastener, the one of the threaded fastener or captive threaded fastener extends through an aperture in a wall of a chassis of an electronics assembly to maintain engagement between the inboard end of the circuit board and the one of the backplane or the circuit card.
A circuit card assembly comprising:
- a first circuit board including a first connector and defining a first threaded receptacle disposed adjacent to the first connector;
- a second circuit board including a second connector and defining a first aperture adjacent to the second connector, the second connector engaging and being electrically connected to the first connector;
- and
- a first threaded fastener extending through the first aperture of the second circuit board and being received in the first threaded receptacle of the first circuit board to maintain engagement between the first connector and the second connector,
- wherein the first threaded fastener extends through an aperture in a wall of a chassis of an electronics assembly to maintain engagement between the first circuit board and the second circuit board.
An electronics assembly comprising:
- a chassis comprising a first wall, the first wall defining a first aperture;
- a first circuit board disposed within the chassis, the first circuit board including a first connector and defining a threaded receptacle disposed adjacent to the first connector;
- a second circuit board disposed within the chassis, the second circuit board comprising a second connector and defining a second aperture, the second connector engaging and being electrically connected to the first connector;
- and
- a threaded fastener extending through the first aperture and the second aperture, and being received in the threaded receptacle of the first circuit board to maintain engagement between the first connector and the second connector, wherein the first circuit board and the second circuit board are differently selected from one of a first circuit card, a second circuit card, or a backplane.
