Abstract
Abstract An electrical connector includes a stamped and formed terminal for establishing electrical contact with a terminal post having a rectilinear cross section. The terminal has at least one resilient beam which has a contact area having an arcuate cross section. The concave surface of the arcuate cross section engages the edge of the terminal posts to provide a good electrical connection even if excess solder is deposited on the exterior of the terminal post in the vicinity of the contact region.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
Apparatus for use in establishing electrical interconnection with traces on a printed circuit board, comprising: a plurality of posts soldered to the traces on the printed circuit board, each post having a rectilinear cross section and having solder flux concentrated on the sides of the posts above the printed circuit board, the thickness of the solder flux at the edges of the rectilinear cross section being less than on the sides intermediate the edges, and an electrical connector having a plurality of terminals, each terminal including at least one axially extending resilient beam, the beam being resiliently deflectable from an initial position and resiliently urged into engagement with the post when positioned adjacent thereto, the resiliently urged beam having a contact section having an arcuate cross section, the concave face of the arcuate cross section being disposable adjacent the post engaging the corners of the post and comprising means for establishing an electrical connection with the terminal post instead of the solder flux concentrated on the sides of the post.
Claim 2
Dependent Claim
170 words
Apparatus for use in establishing electrical interconnection with traces on a printed circuit board, comprising: a plurality of posts soldered to the traces on the printed circuit board, each post having a rectilinear cross section and having solder flux concentrated on the sides of the posts above the printed circuit board, the thickness of the solder flux at the edges of the rectilinear cross section being less than on the sides intermediate the edges, and an electrical connector having a plurality of terminals, each terminal including at least one axially extending resilient beam, the beam being resiliently deflectable from an initial position and resiliently urged into engagement with the post when positioned adjacent thereto, the resiliently urged beam having a contact section having an arcuate cross section, the concave face of the arcuate cross section being disposable adjacent the post engaging the corners of the post and comprising means for establishing an electrical connection with the terminal post instead of the solder flux concentrated on the sides of the post.
Claim 3
Dependent Claim
168 words
Apparatus for use in establishing electrical interconnection with traces on a printed circuit board, comprising: a plurality of posts attached to the printed circuit board, each post having a rectilinear cross section and having a nonconductive contamination concentrated on the sides of the posts above the printed circuit board, the thickness of the nonconductive contamination at the edges of the rectilinear cross section being less than on the sides intermediate the edges, and an electrical connector having a plurality of terminals, each terminal including at least one axially extending resilient beam, the beam being resiliently deflectable from an initial position and resiliently urged into engagement with the post when positioned adjacent thereto, the resiliently urged beam having a contact section having an arcuate cross section, the concave face of the arcuate cross section being disposable adjacent the post engaging the corners of the post and comprising means for establishing an electrical connection with the terminal post instead of the nonconductive contamination concentrated on the sides of the post.
