Electrical connector assembly

An electrical connector (1000) is provided comprising a female member (100) and a male member (500) configured such that the female member is inhibited from being electrically coupled to the male member if the electrical coupling would reverse the polarity of the electrical connector. The female member may comprise a first (110) and second (120) chamber. The male member may comprise a first (510) and second (520) extension. The first and second chambers may be configured to insertably accommodate the first and second extensions. The female member may comprise one or more resilient members (300) providing a pressing force to bias at least a portion of a male electrode against at least a portion of a corresponding female electrode. Alternatively, the cover of the male electrode in the first and second extensions may comprise a resilient member.
