Abstract
A heavy duty connector is disclosed having a plug member and a receptacle member each including a first set of standard terminals and a second set of auxiliary terminals. The subject receptacle will accept a standard plug in a partially mated condition, engaging the first terminals without damaging the second terminals. The subject plug member will fully mate with the subject receptacle, engaging both sets of terminals, and fully mate with a standard receptacle, the second terminals not being engaged. Thus, any combination of the subject and standard connector members are intermatable. The cover of the subject receptacle member is profiled to hold a standard plug in the partially mated condition and the subject plug in a fully mated condition.
