Abstract

The present invention provides a nosebox having an interchangeable connector assembly contained in a housing, for making electrical connection between a tractor and a trailer. The nosebox housing is sized to receive electrical conduits in excess of the size and/or number (seven) proscribed by the SAE J-560 standards and is adapted to securely attach to either the tractor or the trailer. The nosebox housing includes a cover member hingedly attached to a tray member. When closed, the cover member seals against the tray member, thus preventing water from entering the interior of the box. Additionally, the interior of the nosebox is contoured for directing electrical conduits without pinching them.

The interchangeable connector assembly is detachably mounted inside the nosebox housing and is easily removable for repair or replacement. The interchangeable connector assembly also meets SAE-J560b standard. The interchangeable connector assembly offers push-on sealed plug connections, stacking ring-terminal connections, and circuit breaker protection in different embodiments.
