An electrical connector for use with a tractor-trailer includes a receptacle having a generally cylindrical outer body and a molded inner body encapsulating a plurality of conductors secured to connector pins. To provide additional current carrying capacity to accommodate an automatic braking system (ABS) one of the conductors designated as a ground conductor is larger than all of the other conductors. A conductor carrying ABS current is larger than all conductors except the ground conductor. The inner and outer bodies are fastened together by means of a bayonet connection. An additional securing device includes a projection on the inner body which is held in position by means of a bail attached to the outer body. To reduce resistance at the contacts, all contacts are soldered or crimped to their respective conductors and molded within the inner body to protect all wires and connections to the connector pins from environmentally caused corrosion or damage. The outer body includes outward extending flanges for mounting and protection from damage upon operating the bayonet connection. The receptacle provides a protective door for contact connectors when not in use and a latch on the door to engage and lock an external plug when inserted properly.
