  • Patent number: 7581981
    Abstract: An electrical junction box has a fitting member for securing the junction box to a vehicle body. The fitting member has a breakdown accelerating portion for enhancing breakdown of the fitting member when the junction box is pulled to remove it from the vehicle body. The breakdown accelerating portion is positioned in a base side of the fitting piece. By a transverse force caused by pulling an associated wiring harness, the breakdown accelerating portion initiates breakdown of a bracket to separate the junction box from the bracket. Another fitting device has a fitting member formed on a junction box for securing the junction box to a vehicle body. The fitting member has a slot for enhancing breakdown of the fitting member when the junction box is pulled to remove the junction box from the vehicle body, and the fitting member has a compensating piece removably inserted into the slot for adjusting the breakdown of the fitting member.

  • Patent number: 6969276
    Abstract: A metal terminal has a terminal body having a crimp part crimped to a wire and a fastening part connected to the terminal body through breaking parts. The fastening part has a through-hole for passage of a bolt. The metal terminal further includes a co-fastening part formed in the terminal body. The tip side of the co-fastening part is fastened to a vehicle body by the bolt, together with the fastening part. When detaching the terminal body from the vehicle body, one side of the one terminal body is pulled up in a direction opposite to the fastening direction of the bolt under condition that the fastening part and the co-fastening part are together fastened by the bolt. Consequently, the co-fastening part is released from its fastened condition and a breaking force is applied on the breaking parts.
