Abstract: A connector assembly comprising: a first connector having a housing on which an elastic locking piece is suspended; a second connector having a housing on which a locking member mating with the elastic locking piece is formed so as to lock the first and second connectors together when the first and second connectors are mated together; and a connector position assurance device having a first stopper and a second stopper behind the first stopper. A first mating stopper is formed on the elastic locking piece, and a second mating stopper is formed on the housing of the first connector. The connector position assurance device only can be inserted into a first position under the elastic locking piece of the first connector when the first and second connectors are separate from each other.

Abstract: An electrical connector assembly is disclosed having a first connector and a second connector. The first connector has a first engagement portion on a first mating end, and at least one first ridge positioned on and protruding outward from an outer surface of the first engagement portion. The second connector has a second engagement portion on a second mating end. The second engagement portion has a first connector receiving chamber having an inner surface, and at least one second ridge positioned on and protruding inward from the inner surface. The at least one second ridge is positioned on, and protrudes inward from, the inner surface, being in electrical contact with the first ridge when the first engagement portion is positioned in the first connector receiving chamber.
