The electrical connector as recited in claim 1, wherein the electrical contacts comprise electrical signal contacts. 4. The electrical connector as recited in claim 3, wherein adjacent electrical signal contacts define differential signal pairs. 5. The electrical connector as recited in claim 4, wherein the external electrical component comprises a ground plate having a ground plate body and at least one plurality of rib that extends into the leadframe housing at a location between adjacent differential signal pairs. 6. The electrical connector as recited in claim 5, wherein a portion of the at least one rib is substantially coplanar with the electrical signal contacts of the adjacent differential signal pairs. 7. The electrical connector as recited in claim 1, wherein the external electrical component comprises a ground plate having a ground plate body that defines the second engagement surface configured to face the first engagement surface when the ground plate is attached to the leadframe housing. 8. The electrical connector as recited in claim 7, wherein the electrical connector includes a plurality of leadframe assemblies, and the ground plate is disposed between adjacent leadframe assemblies. 9. The electrical connector as recited in claim 8, wherein each of the adjacent leadframe assemblies includes respective leadframe housings and electrical signal contacts carried by the leadframe housings, and the ground plate provides an electrical shield between the electrical signal contacts carried by the leadframe housings. 10. The electrical connector as recited in claim 9, wherein the first engagement member comprises a catch and the second engagement member comprises a latch configured to mate with the catch as the leadframe housing and the ground plate are brought together, and the latch flexes along the direction that is substantially perpendicular to the mating direction as the ground plate is attached to the dielectric leadframe housing. 11. The electrical connector as recited in claim 10, wherein the attachment system further includes an alignment assembly configured to limit relative movement between the ground plate and the leadframe housing as the latch mates with the catch. 12. The electrical connector as recited in claim 10, wherein the latch cams over the catch so as to flex as the leadframe housing and the ground plate are brought together along the mating direction. 13. The electrical connector as recited in claim 12, wherein the catch includes a ramp, and the latch rides along the ramp so as to flex as the leadframe housing and the ground plate are brought together along the mating direction until the latch snaps behind the ramp so as to prevent the ground plate from being separated laterally from the dielectric leadframe housing. 14. A leadframe assembly comprising; a dielectric leadframe housing defining a first outer engagement surface;a plurality of electrical contacts carried by the dielectric leadframe housing;an external plate including a body that defines a second outer engagement surface configured to be attached to the dielectric leadframe housing along a mating direction such that the first and second outer engagement surfaces face each other; andan attachment system including: an attachment assembly including a latch carried by one of the leadframe housing and the external plate, and a catch carried by the other of the leadframe housing and the external plate, wherein the latch and the catch are configured to mate with each other along the mating direction so that at least a portion of the latch overlaps at least a portion of the catch along a first direction that is substantially perpendicular to the mating direction so that the latch and the catch mechanically interfere with each other and lock the external plate to the dielectric leadframe housing with respect to separation of the external plate from the leadframe housing along a direction that is opposite the mating direction; andan alignment assembly that operatively aligns the leadframe housing and the external plate such that the latch and the catch are configured to mate with each other along the mating direction. 15. The electrical connector as recited in claim 14, wherein the plate comprises an electrical shield. 16. The leadframe assembly as recited in claim 14, wherein the latch flexes along the first direction as the latch overlaps at least a portion of the catch. 17. The leadframe assembly as recited in claim 16, wherein the latch flexes along a direction opposite the first direction as the latch and the catch mate along the mating direction. 18. An electrical connector comprising: a plurality of leadframe assemblies that include a leadframe housing defining a first outer engagement surface, electrical signal contacts carried by the leadframe housing, and a ground plate that provides an electrical shield between the electrical signal contacts carried by adjacent ones of the leadframe housings, wherein the ground plate includes a ground plate body that defines a second outer engagement surface configured to be attached to the dielectric leadframe housing along a mating direction such that the first and second outer engagement surfaces face each other; andan attachment system carried by at least one select one of the plurality of leadframe assemblies, the attachment system including: a latch carried by the ground plate body, wherein the latch is configured to flex as the leadframe housing and the ground plate are brought together along the mating direction, and wherein the latch is devoid of apertures that extend through the ground plate;a catch carried by the first outer surface of the dielectric leadframe housing, wherein the catch causes the latch to deflect along a direction substantially perpendicular with respect to the mating direction as the latch and catch mate, and wherein the latch and catch are configured to mate as the leadframe housing and the ground plate are brought together so as to lock the ground plate to the leadframe housing, thereby resisting separation of the ground plate from the leadframe housing; andan alignment assembly configured to limit relative movement between the ground plate and the leadframe housing as the latch mates with the catch. 19.
