An electric junction box for a vehicle is assembled by fitting and locking a connector through an aperture provided in a main case; the aperture being used for fitting the connector that holds a retainer at a temporary latch location, the retainer providing a double latch for a terminal; inserting and latching the terminal of an electric wire into the connector; and pushing the retainer into a full latch position. A recess for retainer operation is provided at a location facing the retainer and on a surrounding wall of the main case that surrounds the aperture.

Electric junction box for a vehicle

An electrical connection box has a substrate carrying electrical components, a molded synthetic resin casing fitted on the substrate at the lower side thereof, and a connector receivable in the casing and mountable at a predetermined position on the substrate. The connector has electrical, terminals engageable with electrical terminals of the substrate. A fastener is inserted in the substrate to draw the connector to its predetermined position. A holder for the connector is molded in one piece with the casing, and is open at its upper side to receive the connector. The connector and the holder have holding elements which are mutually engageable to hold the connector in the holder, prior to the operation of the fastener to draw the connector to its predetermined position, whereby the fastener through the connector holds the casing at its fitted position on the substrate.

Electrical connection box

When an electrical connection box body is installed on a vehicle body, for a temporary pivotable mounting of the box body on the vehicle body, one of the box body and the vehicle body has a shaft and the other has a bracket to receive the shaft at a predetermined location, so as to allow pivoting of the box body about the shaft axis. Locating guide surfaces position the box body relative to the vehicle body during mounting, prior to receipt of the shaft at said predetermined location on the bracket. This makes the operation of installing the box easier and more precise and avoids looseness of the box body during assembly operations carried out on the box.
