Electrical connector

摘要

An electrical connector (10) includes a connector body (12) and an array of posts (30,30') extending out of one side of the connector body for mounting to a circuit board (60). Each of the posts (30,30') defines a tip and two opposed pairs of post faces (38) that intersect at edges (40) extending along the post. The tip (42) defines four tip faces (44) which converge toward a tip nose (46) and each tip face (44) is aligned with a respective one of the post faces (38). Each of the tip faces (44) is convex outwardly, and the edges between the post faces (38) adjacent the tip are curved with a radius of curvature greater than about 0.005 inches. The electrical connector (10) is assembled by press fitting the posts (30,30') through pre-formed through holes (66), and the tip geometry reduces skiving of material out of the through hole (66) as well as assembly forces. At least one retention feature is provided, and this retention feature includes a bent portion of at least one of the posts (30,30'). The bent portion includes a first portion extending from the centerline of the post to an apex, and a second portion extending from the apex (74) to the tip (42) such that the apex (74) is laterally offset from the centerline to a greater extent than is the tip (42). At least the first and second portions are formed of post stock having four faces that intersect at radiused edges, wherein each of the radiused edges defines a radius of curvature no less than about 0.005 inches. The retention feature is configured such that the apex (74) is situated outside of the respective through hole (66) when the electrical connector (10) is positioned on a circuit board (60).
