Electrical junction box
View Patent ↗A relay part is housed in a case, a fuse mounting part is provided above the relay part in the case and a fuse is attached/detached to/from the fuse mounting part from above the case. In the case, provided are an internal cover and a bus bar supporting resin body, which cover the periphery of the relay part. A drainage channel is provided in outer surfaces of the internal cover and the bus bar supporting resin body. In addition, a drainage hole which drains water flowing through the drainage channel to the outside of the case is provided in the case. The drainage channel includes an upper groove which is formed in an upper surface of the bus bar supporting resin body and has an inclined surface on its bottom and a side groove which is communicated with a lowest portion of the inclined surface of the upper groove and is formed on a side of the internal cover.
1. An electrical junction box comprising:
a first bus bar which has a power terminal formed therein and distributes and supplies power derived from the power terminal;
a second bus bar in which a plurality of relay parts, to which power is supplied from the first bus bar, are fixed to each relay fixing part and control terminals and output terminals of the relay parts are formed; and
a case which houses the first and second bus bars therein and has a connector cavity part in which the power terminal, the control terminals and the output terminals are arranged,
wherein, in the second bus bar, a folded part which is folded in a plane direction that the second bus bar is formed, and the folded part is folded substantially at a right angle to a direction in which the relay parts are fixed to the relay fixing part and is folded substantially at a right angle to the control terminals and the output terminals.
2. The electrical junction box according to claim 1 , wherein
the folded part is set between the relay fixing part and each of the control terminals and output terminals, providing a connection range wherein the control terminals and the output terminals can be arranged in the connector cavity.
3. The electrical junction box according to claim 1 , wherein
the control terminals and the output terminals extend from the periphery of the relay fixing part and the folded part, and are arranged in the connector cavity.
4. The electrical junction box according to claim 1 , wherein the relay fixing part, the control terminals, and the output terminals are formed as one.
5. An electrical junction box comprising:
a first bus bar which has a power terminal formed therein and distributes and supplies power derived form the power terminal;
a second bus bar in which a plurality of relay parts, to which power is supplied from the first bus bar, are fixed to each relay fixing part and control terminals and output terminals of the relay parts are formed; and
a case which houses the first and second bus bars therein and has a connector cavity part in which the power terminal, the control terminals and the output terminals are arranged,
wherein, in the second bus bar, a folded part which is folded in a plane direction that the second bus bar is formed, and
wherein the control terminals and the output terminals extend from the periphery of the relay fixing part and the folded part, and are arranged in the connector cavity.
