[Embodiment 2]
The board connector, the electronic component unit, and the wire harness according to the second embodiment are different from the first embodiment in that a part of the connector terminals and the connection terminals are integrally formed. In the following, the same components as those in the above-described embodiment are designated by a common reference numeral, and the common configurations, actions, and effects will be omitted as much as possible (the same shall apply hereinafter).

The wire harness WH2 of the present embodiment shown in FIGS. 9 and 10 is different from the wire harness WH1 described above in that the electronic component unit 201 is provided instead of the electronic component unit 1.

The other part (second connector terminal 241B) is formed integrally with any one of the plurality of connection terminals 244. With this configuration, in the board connector 204, the electronic component unit 201, and the wire harness WH2, a part of the connector terminal 241 (second connector terminal 241B) and the connection terminal 44 are shared by the L-shaped terminal 245, and the above-mentioned It is possible to suppress the increase in size.

The substrate connector, the electronic component unit, and the wire harness according to the above-described embodiment of the present invention are not limited to the above-described embodiment, and various modifications can be made within the scope of the claims. ..

In the above description, the board connectors 4 and 204 have been described as forming a so-called connector for a power supply BOX with a joint function, but the present invention is not limited to this. For example, in the above description, the connection boards 43 and 243 have been described as having a wiring pattern 43c for conductively connecting at least two or more connector terminals 41 to a common connection terminal 44, but the present invention is not limited to this. That is, the wiring pattern 43c is not limited to the joint circuit in which two or more connector terminals 41 are conductively connected to the common connection terminal 44, and can be any circuit according to the request. The wiring pattern 43c may be, for example, a circuit in which a plurality of connector terminals 41, 241 and a plurality of connection terminals 44, 244 are made to correspond one-to-one and are conductively connected. Even in this case, the connection terminals 44 and 244 may be arranged in a line along the third direction Z so as to be electrically connected to the main board 3.

The board connector, the electronic component unit, and the wire harness according to the present embodiment may be configured by appropriately combining the components of the embodiments and modifications described above.
