An electrical junction box is configured to be attached to a vehicle. The box includes a container that has a front opening and a cavity located behind the front opening. A cover is movably attached to the container, so it can be moved into a closed position covering the front opening. A socket, to which an electrical supply cable can be removably connected, is fixed to the container beside the front opening. Breakers are secured to the container within the cavity. Each breaker has an input terminal and an output terminal. Each input terminal is electrically connected to the supply cable via the socket. Electrical distribution lines connect the breakers' output terminals to components of the vehicle that are outside the cavity.

In accordance with the teachings described herein, systems and methods are provided for supplying power to a vehicle trailer. A connection device may be used to connect the vehicle trailer to a vehicle power line and to a control line from a vehicle electrical system. The trailer may include a main trailer electrical system and an auxiliary trailer electrical system. The main trailer electrical system requires power only when the vehicle trailer is in motion, and may be coupled to the connection device to receive power from the vehicle power line. A control unit may be coupled to the connection device, and may receive a control signal from the control line. The control unit may be used to switchably couple the auxiliary trailer electrical system to the vehicle power line based on the control signal.

A cartridge for removably connecting to a cable that electrically connects a tow vehicle to a towed vehicle is provided. The cartridge includes a body having a first end and a second end and a plurality of openings extending from the first end to the second end. The cartridge also includes a common contact member having a female contact end and a male contact end, wherein the female contact end is disposed in and the male contact extends from a corresponding one of the plurality of openings, and wherein the female contact end has an outer diameter that is smaller than an inner diameter of the corresponding body opening in which it is disposed to allow for a lateral movement of the female contact end within the body. The cartridge also includes a plurality of noncommon contact members each having a female contact end and a male contact end, wherein each female contact end is disposed in and each male contact extends from a corresponding one of the plurality of openings, and wherein each female contact end has an outer diameter that is smaller than an inner diameter of the corresponding body opening in which it is disposed to allow for a lateral movement of each female contact end within the body.

An electrical wiring system is described for providing required and other electrical signals and functions between a truck tractor and a trailer coupled for towing to the tractor. The tractor has an operator cab and may include a sleeper compartment (box) behind the cab. The wiring system provides efficiencies in manufacture of the tractor, particularly when it includes a sleeper box which the tractor manufacturer may offer in a range of lengths. The wiring system includes a cable module for the cab and a standard-length cable module for the sleeper box. The cab cable module terminates at its rear end in a connector to which can be connected either a socket assembly for a removable tractor-to-trailer cable unit having end connectors conforming to an applicable Standard, or a connector at the forward end of the sleeper box cable module, or a tractor-to-trailer cable unit which is more permanently connected to the tractor. The rear end of the sleeper box cable module terminates in a connector which can be a duplicate of the connector of the cab cable module.

A holder, mountable on the back of a truck tractor cab, has two electrical plug receptacles and two gladhand keepers. The gladhand keepers are vertically directed and angled with respect to the mounting surface of the cab, so that an operator can store in the keepers the hose-end gladhands associated with the tractor without climbing on, leaning over, or stretching across the frame of the truck behind the cab. The electrical plug receptacles are at an angle away from the surface, making it easier for an operator to insert the plugs into the electrical plug receptacle and thereby reducing wear to the cables.

An integrated pressure exhaust valve and pneumatic coupling is used on a truck trailer for bringing air brake pressure from a tractor to the truck trailer. A gladhand coupling moiety is used for quick connection with an identical coupling moiety on the air pressure hose from the tractor. A check valve mechanism is incorporated in the body of the trailer coupling moiety for permitting air flow to the brakes when pressure from the tractor is greater than pressure in the trailer brake lines, and for permitting air flow from the brake lines to the atmosphere when pressure from the tractor is decreased. The integrated pressure exhaust valve and pneumatic coupling moiety can be mounted on the front of the trailer where it is found that pressure exhaust valve placement is most effective.

Integrated pressure exhaust valve and fluid coupling

An insulated door for a refrigeration vehicle includes spaced walls between which there is an insulation material. Hardware such as hinges and latches are mounted to the door by fastening the hardware to a rigid support mounted on the outside wall of the door, and providing openings in the support for accommodating fastening elements whereby the hardware is affixed to the support and the fastening elements do not thereby penetrate through the door walls.
