Electrical junction box
The configuration of an electrical junction box is simplified and made compact. Provided is an electrical junction box for a vehicle, including a housing that accommodates a high-voltage circuit for high voltages and a low-voltage circuit for low voltages, the electrical junction box including a connection portion for connection to the outside, the connection portion being provided on the housing, wherein the connection portion has both a high-voltage terminal connected to the high-voltage circuit and a low-voltage terminal connected to the low-voltage circuit.
1. An electrical junction box for a vehicle, comprising a housing that accommodates a high-voltage circuit for high voltages and a low-voltage circuit for low voltages,
the electrical junction box comprising:
a connection portion for connection to an external device, the connection portion being provided on the housing,
wherein the connection portion has a recessed engagement portion that is engageable with the external device,
an end portion of a high-voltage terminal connected to the high-voltage circuit and an end portion of a low-voltage terminal connected to the low-voltage circuit are exposed to an outside via through holes formed in a bottom of the engagement portion, and
a partition plate having a first surface opposite of a second surface that is disposed in a space between the end portion of the high-voltage terminal and the end portion of the low-voltage terminal is provided extending upright from the bottom, wherein the first surface is entirely spaced apart from the high-voltage terminal and the second surface is entirely spaced apart from the low-voltage terminal.
2. The electrical junction box according to claim 1 ,
wherein a plurality of the partition plates are provided, and a distance between the plurality of partition plates is 1 mm or more.
3. The electrical junction box according to claim 1 ,
wherein a fin is provided protruding from a surface of the partition plate that opposes the end portion of the high-voltage terminal or the end portion of the low-voltage terminal, and extends parallel to the bottom.
4. The electrical junction box according to claim 3 ,
wherein a plurality of the fins are provided, and a distance between the plurality of fins is 1 mm or more.
5. The electrical junction box according to claim 1 ,
wherein the connection portion has a recessed engagement portion that is engageable with the external device,
