Abstract
A controlled-power RJ45 socket includes a housing having a cavity to receive an RJ45 plug. The socket further includes electrical contacts positioned in the cavity and that come in contact with electrical contacts of the RJ45 plug when the RJ45 plug is plugged into the RJ45 socket. A switch is positioned to disconnect the power to the electrical contacts of the RJ45 socket before the electrical contacts of the RJ45 plug are physically detached from the electrical contacts of the RJ45 socket during a de-mating of the RJ45 plug from the RJ45 socket.
Claims15
An RJ45 socket having controlled power and comprising:
- a housing having a cavity to receive an RJ45 plug;
- electrical contacts positioned in the cavity to come in contact with electrical contacts of the RJ45 plug when the RJ45 plug is plugged into the RJ45 socket;
- and
- a switch positioned at least partially in the cavity to disconnect power to the electrical contacts of the RJ45 socket based on positions of the RJ45 plug in the cavity, wherein the switch is positioned to disconnect the power to the electrical contacts of the RJ45 socket before the electrical contacts of the RJ45 plug are physically detached from the electrical contacts of the RJ45 socket during a de-mating of the RJ45 plug from the RJ45 socket and wherein the switch is positioned such that the switch is depressed by a locking tab of the RJ45 plug when the RJ45 plug is mated with the RJ45 socket.
An RJ45 socket having controlled power and comprising:
- a housing having a cavity to receive an RJ45 plug;
- electrical contacts positioned in the cavity to come in contact with electrical contacts of the RJ45 plug when the RJ45 plug is plugged into the RJ45 socket;
- and
- a switch positioned at least partially in the cavity and configured to send an electrical signal to a controller that is external to the housing, the electrical signal indicating whether the switch is depressed or undepressed, wherein the switch is depressed by the RJ45 plug when the RJ45 plug is mated with the RJ45 socket, wherein the controller controls whether power is provided to the electrical contacts of the RJ45 socket based on whether the electrical signal indicates that the switch is depressed or undepressed, wherein the controller disconnects the power before the electrical contacts of the RJ45 plug are physically detached from the electrical contacts of the RJ45 socket during de-mating of the RJ45 plug from the RJ45 socket.
