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.

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.

Abstract: A metal terminal has a terminal body (19) having a crimp part (5) crimped to a wire and a fastening part (25) connected to the terminal body (19) through breaking parts (21, 21). The fastening part (25) has a through-hole (23) for passage of a bolt (7). The metal terminal further includes a co-fastening part (27) formed in the terminal body (19). The tip side of the co-fastening part (27) is fastened to a vehicle body (13) by the bolt (7), together with the fastening part (25). When detaching terminal body (19) from the vehicle body (13), one side of the one terminal body (19) is pulled up in a direction opposite to the fastening direction of the bolt (7) under condition that the fastening part (25) and the co-fastening part (27) are together fastened by the bolt (7). Consequently, the co-fastening part (27) is released from its fastened condition and a breaking force is applied on the breaking parts (21, 21).

Abstract: An electric connection box includes a cover fitted on a lower side of a body having mounting portions, and the cover is fixedly secured to a vehicle body. A wire harness is extended outwardly from a portion of the body, disposed near to one corner portion thereof, through an escape groove. Plural lock mechanisms, in which a lock piece portion can be elastically fitted into a lock groove, are provided at fitting peripheral surfaces of the body and cover, and are disposed near to four corner portions thereof respectively. One lock mechanism, disposed near to a position where the wire harness is extended outwardly, has a semi-lock structure, and thus has a smaller retaining force than the other lock mechanisms.

Abstract: An electric wire is inserted through a through hole formed with a housing body. A first terminal fitting is provided with a first clamper which clamps a portion of the electric wire situated inside of the housing body to electrically connect therewith. A second terminal fitting is provided with a second clamper which clamps a portion of the electric wire situated outside of the housing body. A grommet made of an elastic material has a cylindrical shape such that the electric wire is passed through an inner periphery thereof and an outer periphery thereof is fitted into the through hole of the housing body. A reinforcing spacer is provided on a part of the outer periphery of the grommet so as to abut against at least one of a first edge of the through hole at an outer face of the housing body and a second edge of the through hole at an inner face of the housing body. The reinforcing spacer is made of a material having greater hardness than the elastic material forming the grommet.
