| Inventor(s) | Minich; Steven E. (York, PA) |
| Abstract | An electrical connector is disclosed with a connector housing and a
leadframe assembly received in the connector housing. The leadframe
assembly may include a dielectric leadframe housing and first and second
electrically-conductive contacts extending through the leadframe housing.
Each of the contacts may define a respective broadside and a respective
mating end. The leadframe housing may define a hinge between the mating
ends of the first and second contacts. The leadframe housing may be
folded along the hinge such that the broadside of the first contact is
positioned along the broadside of the second contact. A method for
manufacturing such an electrical connector may include stamping a
leadframe from a sheet of electrically-conductive material, overmolding a
hinged, leadframe housing onto the leadframe, folding the leadframe along
the hinge such that a face of a first contact is positioned along a face
of a second contact, and inserting the folded leadframe assembly into a
connector housing such that the leadframe assembly is retained in the
connector housing in a folded configuration. |
