Abstract: An electrical connector for electrically connecting two objects together, such as a vehicle and a trailer, utilizing receptacle and plug members connected to wire assemblies. The receptacle member has a housing with a bore and a first contact assembly located in the bore. The first contact assembly base has channels that slidably receive pins. Springs bias the pins to extend past the base and into the bore. The plug member has a housing with an insert portion and a second contact assembly located in the insert portion. The second contact assembly base has channels that hold pins flush with the forward end of the base. The insert portion is received in the receptacle bore so the pins abut. The spring biased pins of the receptacle maintain contact when the connector is subject to vibration. Sealing mechanisms on the insert portion seal against the inside of the receptacle bore.
