Since the magnetic force works so as to help the terminals 52 to come into contact with each other, the first connection terminals 82 and the second connection terminals 52 can be reliably electrically connected without uneven contact.

A third magnet 57 located on the opposite side of the first connector 80 and the second connector 50 is provided. 53, when the first connector 80 is pulled out from the second connector 50, the second magnet 53 of the second connector is attracted by the third magnet 57 to keep the second connector member 51 open. be able to.

Since the stopper member 56 is provided on the back side of the second connector 50 as an over-rotation prevention structure for preventing over-rotation, when the first connector 80 is inserted into the second connector 50, the second connector member 51 It can be maintained in a proper position so that it can rotate under the load from the first connector 80 .

According to the preferred embodiment of the present invention, the first connector 80 is provided on the PCU 75 and the second connector 50 is the connector connected to the battery 29 so that the PCU 75 can be easily and conveniently connected to the connector connected to the battery 29. Electrical connection can be reliably made.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various design changes are possible without departing from the gist of the present invention. Of course, it includes those implemented in various modes.

In the electrical connection structure of one embodiment of the present invention, the second connector member 51 rotates due to the load of inserting the first connector 80 into the second connector 50, and the first connection terminal 82 and the second connection terminal 52 are connected. However, for example, the load of inserting the first connector into the second connector causes a crank mechanism, a link mechanism, or the like to work, and through these mechanisms, the first connector is connected to the second connector. The second connector may be moved parallel to the first connector so as to be electrically connected/disconnected in a direction different from the direction in which it is inserted into the connector.
For convenience of explanation, the left-right arrangement of the illustrated embodiment has been described, but the present invention includes a different left-right arrangement as long as it is within the scope of the invention.
