摘要
An edge connector on a printed circuit board (“PCB”) uses a magnetic force to retain the PCB connected to another connector and to reduce the insertion force. In an example embodiment, a male edge connector includes a first magnetic connector and a female connector includes a second magnetic connector. A first force of attraction between the first magnetic connector and the second magnetic connector holds the male edge connector inserted into the female connector. The first force of attraction further reduces the force required to insert the male edge connector into the female connector.

The described example embodiments in general relate to connectors for connecting to a printed circuit board (“PCB”). A PCB may include a connector to connect the PCB to other PCBs or to other devices. The connector on the PCB may be along the edge of the PCB, which is referred to as an edge connector. Generally, an edge connector on a PCB is a male connector that inserts into a female connector to establish a mechanical and electrical connection. Prior art edge connectors have used stamped contact pins with weld tabs to increase the mechanical strength of connection between the male edge connector and the female connector. Connectors would benefit from a system that uses a magnetic force to connect the edge connector to another connector.
