Electrical junction box
An electrical junction box includes: an electrical junction box housing; and a common relay block, an individual corresponding relay block, a common power supply block, and an individual corresponding semiconductor module. The common relay block, the individual corresponding relay block, the common power supply block, and the individual corresponding semiconductor module are attached to the electrical junction box housing.
1. An electrical junction box comprising:
an electrical junction box housing; and
a common relay block, an individual corresponding relay block, a common power supply block, and an individual corresponding semiconductor module, which are attached to the electrical junction box housing,
wherein the electrical junction box housing has a storing chamber, and
wherein at least one block of the common relay block, the individual corresponding relay block and the common power supply block, and the individual corresponding semiconductor module are stored in the storing chamber of the electrical junction box housing, and a block that is not stored is stored in a storing chamber formed in the block that is stored.
2. The electrical junction box according to claim 1 ,
wherein the common relay block has an individual corresponding relay block storing chamber and a common power supply block storing chamber, and
wherein the individual corresponding relay block is stored in the individual corresponding relay block storing chamber, and the common power supply block is stored in the common power supply block storing chamber.
3. The electrical junction box according to claim 1 ,
wherein the individual corresponding semiconductor module includes a plurality of kinds of modules having a same shape.
4. The electrical junction box according to claim 1 ,
wherein each of the common relay block, the individual corresponding relay block, the common power supply block and the individual corresponding semiconductor module comprises a bus bar that is electrically connectable to one another when fitted to one another.
5. The electrical junction box according to claim 1 ,
wherein each of the electrical junction box housing, the common relay block, the individual corresponding relay block, the common power supply block and the individual corresponding semiconductor module comprises a guide portion that can guide one another and a locking portion that can lock one another when fitted to one another.
