Electrical plug connector with blade receiving slots

An electrical connector for mating with a connector having a plurality of parallel blade contacts arrayed within a plug receiving cavity, comprising:

• an insulating housing, a front portion of the housing comprising an elongated plug, a plurality of parallel elongated cavities bridging transversely across the plug, a mouth of each of the cavities comprising a respective elongated, blade receiving, narrow slot, each said narrow slot communicating with a corresponding one of the cavities and aligned therewith, a conductive electrical contact in each of the cavities, each of the contacts having thin leaf sides on a blade receiving receptacle, each receptacle being positioned beneath and aligned with a corresponding narrow slot such that contact surfaces defined on said thin leaf sides are parallel with said narrow slot to be engaged with opposed side surfaces of a respective said blade contact inserted thereinto and substantially parallel to direction of insertion of the contact into a respective one of the cavities, and edges on respective thin leaf sides being overlapped by undercut shelves along an intersection of the corresponding narrow slot with the respective cavity.
