Power line communication apparatus
View Patent ↗A communication apparatus includes a communication board provided with a Power Line Communication (PLC) signal processor so as to be used in common in other apparatuses. The communication apparatus performs communication through a power line and a transmission medium different from the power line. The communication apparatus includes a power board that is provided with a power supply connected to the power line, an interface board that is separately formed from the power board and is provided with an interface for performing communication through the transmission medium, and a communication board that is separately formed from the power board and the interface board. The communication board is provided with a power line communicator for performing communication through the power line and a connector electrically connectable to the power board and the interface board.
1. A communication apparatus which performs communication through a power line and a transmission medium different from the power line, the communication apparatus comprising:
a power board which is provided with a power supply connected to the power line through an electrical plug that is attached to the power board;
an interface board which is separately formed from the power board and is provided with an interface for performing communication through the transmission medium;
a communication board which is separately formed from the power board and the interface board, and is provided with a power line communicator for performing communication through the power line;
a first connector which connects electrically the communication board to the power board and includes a transmission path for a power line communication signal;
a second connector which connects electrically the communication board to the interface board, includes a transmission path for a communication signal transmitted and received through the interface board, and is provided at a location away from the first connector; and
a heat radiator that radiates heat generated from the communication board,
wherein the communication board is substantially perpendicular to both the power board and the interface board, and
wherein the heat radiator holds the communication board and is disposed at a location facing the power board so as not to overlap the power plug.
2. The communication apparatus according to claim 1 ,
wherein the power board includes a coupler for separating and coupling the power line communication signal, and
wherein the first connector is disposed in the vicinity of the coupler.
3. The communication apparatus according to claim 1 , further comprising:
a casing which accommodates the power board, the interface board, and the communication board;
wherein the power plug is provided on a surface of the casing; and
wherein a base portion of the power plug is connected to the power board.
4. The communication apparatus according to claim 3 ,
wherein the heat radiator includes:
an extender which extends from the communication board at a location facing the power board; and
a regulator which regulates displacement of an end portion of the extension portion toward the power board.
5. The communication apparatus according to claim 1 ,
wherein the interface is an interface for wireless communication.
6. The communication apparatus according to claim 1 ,
wherein the interface is an interface for a coaxial cable.
7. The communication apparatus according to claim 1 ,
wherein the power supply provides power to both the interface board and the communication board.
