Electrical junction box
An electrical junction box includes a case body having a plurality of connector portions, a power supply side circuit board accommodated in the case body and a spare connector mounting portion provided in an upper portion of the case body and configured such that a spare connector is attached to and detached from the spare connector mounting portion. The spare connector includes a fuse configured to electrically connect the power supply side circuit board to a device side terminal connected to an end of an electric wire configured to be electrically connected to an electronic device.
1. An electrical junction box comprising:
a case body having a plurality of connector portions;
a power supply side circuit board accommodated in the case body;
a spare connector mounting portion provided in an upper portion of the case body and configured such that a spare connector is attachable and detachable from the spare connector mounting portion; and
the spare connector,
wherein the spare connector includes:
a connector housing configured to receive a fuse in an opening of the connector housing, at an upper side of the connector housing; and
the fuse, the fuse electrically connecting the power supply side circuit board to a device side terminal connected to one end of an electric wire,
the device side terminal is accommodated in the connector housing, and the electric wire is configured to be electrically connected to an electronic device, and
the electric wire, from the one end which is connected to the device side terminal accommodated in the connector housing, extends toward a lower side of the spare connector and then towards an upper side of the spare connector.
2. The electrical junction box according to claim 1 ,
wherein a power supply side terminal of the fuse electrically connected to a terminal connection portion of the power supply side circuit board.
3. The electric junction box according to claim 1 ,
wherein the spare connector includes an electric wire holding portion configured to hold the electric wire, in a state of being pulled out toward an upper side of the spare connector.
4. The electrical junction box according to claim 1 ,
wherein the spare connector is configured to be locked and fixed to the spare connector mounting portion via a locking mechanism configured to be released from above the case body.
5. The electrical junction box according to claim 3 ,
wherein the electric wire extends out of an opening of the connector housing, at a lower side of the connector housing, and then towards the upper side of the spare connector in a first direction through the electric wire holding portion.
6. The electrical junction box according to claim 5 , wherein, in a plan view of the electrical junction box, the electric wire holding portion has a C shape that is configured to receive the electric wire in a second direction perpendicular to the first direction.
