In the circuit structure of the third connection method, the polarity of the first main terminal fitting 31 and the second main terminal fitting 33 are reversed with respect to the circuit structure of the first connection method.
[0098] In addition, in the storage chamber 50a, the third terminal fitting 35 of the third electric wire with terminal 13 can be changed from the second screw fastening structure 72 to the fifth screw fastening structure 75.

For example, compared with the case where the connectors for the first circuit and the second circuit are provided for each fuse, cost reduction can be achieved, and the space efficiency of the connector installation location in the installation object and the connection object can be improved. In addition, the connector 1 of the present embodiment not only adopts a threaded fastening structure in the connection of the terminal fittings of each terminal wire (the first terminal wire 11, the second terminal wire 12, the third terminal wire 13, the fourth terminal wire 14, the fifth terminal wire 15, and the sixth terminal wire 16), but also adopts a threaded fastening structure in the connection of the terminal fittings of each terminal wire (the first terminal wire 11, the second terminal wire 12, the third terminal wire 13, the fourth terminal wire 14, the fifth terminal wire 15, and the sixth terminal wire 16). Therefore, by changing the connection target of each terminal fitting, the circuit structure of the first circuit 10A and the second circuit 10B can be easily changed. For example, in the previous example, by changing the connection target of the terminal accessory, the polarity of the first main terminal accessory 31 and the second main terminal accessory 33 can be swapped, or the polarity of the third wire 23 and the fourth wire 24 electrically connected to the first external electrical device can be swapped, or the polarity of the fifth wire 25 and the sixth wire 26 electrically connected to the second external electrical device can be swapped.
[0101] In addition, in the connector 1, for example, when the circuit of either the first circuit 10A or the second circuit 10B is not required, if the fuses related to the unnecessary circuit in the first fuse 41 and the second fuse 42 are not assembled, only the circuit of the other of the first circuit 10A and the second circuit 10B can be formed.
[0102] In addition, in the connector 1, as previously shown, by limiting the shapes (their body shape, through-hole spacing) of the first fuse 41 and the second fuse 42 to only one specification, it is possible to use the same components with the same shape and capacity in the first fuse 41 and the second fuse 42, or to use different components with the same shape but different capacities in the first fuse 41 and the second fuse 42.
[0103] In this way, the connector 1 of the present embodiment can easily cope with changes in circuit specifications.
