Power conversion device
View Patent ↗To effectively suppress radiation and mixture of noise superimposed on a power line into a connection detection line. A power conversion device includes a connector having a wiring line which transmits DC power; and a housing in which the connector is arranged. The connector has a connection detection wiring line which detects whether the connector is connected with an external circuit. An opening part which connects with the connector is formed in the housing. An annular core formed of a magnetic substance is inserted through the opening part. The annular core is an annular member formed with a through-hole. The wiring line and the connection detection wiring line are introduced into an inside of the housing through the through-hole of the annular core.
1. A power conversion device, comprising:
a connector having a wiring line which transmits DC power; and
a housing in which the connector is arranged,
wherein the connector has a connection detection wiring line which detects whether the connector is connected with an external circuit,
the connection detection wiring line is introduced into an inside of the housing through an inner peripheral side of an annular core formed of a magnetic substance, and
wherein a partition member is arranged between the wiring line and the connection detection wiring line, and the annular core is sandwiched between the housing and the partition member.
2. The power conversion device according to claim 1 , wherein the wiring line which transmits the DC power is introduced into the inside of the housing through the inner peripheral side of the annular core.
3. The power conversion device according to claim 2 , wherein an opening part which connects with the connector is formed in the housing, and
the annular core is inserted through the opening part.
4. The power conversion device according to claim 1 , wherein the partition member has a core fixing part.
5. The power conversion device according to claim 1 , wherein the partition member has a partition wall which protrudes to the inner peripheral side of the annular core, and
the wiring line and the connection detection wiring line are separated by the partition wall on the inner peripheral side of the annular core.
