<p>PURPOSE:To prevent the erroneous fitting of a wire harness male connector in an electric junction box without changing the shape of the connector and without using other parts. CONSTITUTION:Bus bars are utilized to form male tab terminals 7 in a junction box female connector 2, one of the male tabs 7 is omitted, and an erroneous assembling preventing tab 8 capable of being inserted into the terminal storage chamber of a wire harness male connector 3 is formed in its place. In the normal coupling, the terminal storage chamber of the wire harness male connector 3 to be inserted with the erroneous assembling preventing tab 8 is set to the vacant terminal state to realize coupling. In the erroneous coupling, the erroneous coupling preventing tab 8 collides with the female terminal of the wire harness male connector 3, and no coupling is allowed.</p> |
