An electrical connector assembly comprising: an insulative housing including an elongated main body defining upper and lower rows of passageways; upper and lower rows of contacts disposed in the corresponding passageways, respectively; a rear portion extending rearwardly from an upper portion of a rear face of the main body; a plurality of recesses disposed in the rear portion; a printed circuit board located under the rear portion, around a mid-level relative to the housing and behind the rear face of the main body with a gap therebetween in a front-to-back direction; the contacts of the lower row defining a trough-like tail portion including a horizontal mounting portion engageably received in the corresponding recess and vertically spaced from the printed circuit board, a first connecting portion obliquely downwardly extending from an inner end of said horizontal mounting portion, and a second connecting portion downwardly from an outer end of the horizontal mounting portion with an distal end soldered on the printed circuit board; wherein said first connecting portion extends obliquely downwardly beyond the printed circuit board and cross the gap, and terminates at a position horizontally aligned with the corresponding passageway of the lower row. 9. The assembly as described in claim 8, wherein an upper portion of said first connecting portion abuts against a slanted surface in the corresponding recess.10. The assembly as described in claim 8, wherein said horizontal mounting portion provides retention in the corresponding recess. US-6468097, 20021000, Bernstein et al., 439/181 ttached to the bracket base such that the ligation cover is selectively rotatable about a hinge between the open, non-ligating position and the closed, ligating position.8. An orthodontic bracket as defined in claim 7, wherein the ligation cover is hingedly attached to the bracket base by means of a film hinge of locally reduced cross-sectional thickness.9. An orthodontic bracket as defined in claim 8, wherein the ligation cover and bracket base are molded as single, one-piece unit.10. An orthodontic bracket as defined in claim 8, wherein the bracket base and ligation cover are separately formed and then joined together by a two-color molding process so as to yield an integral, one-piece bracket.11. An orthodontic bracket as defined in claim 7, wherein the ligation cover is hingedly attached to the bracket base by means of a fiber hinge.12. An orthodontic bracket as defined in claim 7, wherein the ligation cover is hingedly attached to the bracket base by means of an elastomeric adhesive interconnecting the ligation cover and bracket base.13. An orthodontic bracket as defined in claim 1, wherein the ligation cover includes a bearing protrusion configured and positioned so as to engage one or more arch wires while the ligation cover is in the closed, ligating position.14. An orthodontic bracket as defined in claim 13, wherein the ligation cover is configured so as to absorb mechanical energy from an arch wire when not entirely seated relative to the bracket base.15. An orthodontic bracket as defined in claim 1, further including a spring connected at one end to the ligation cover and at an opposite end to the bracket base, the spring being positioned and tensioned relative to the ligation cover and bracket base so as to urge the ligation cover to remain closed while the closed, ligating position and to remain open while in the open, non-ligating position.16. An orthodontic bracket comprising: a bracket base that includes a first arch wire slot in a top of the bracket base and a second arch wire slot in a side of the bracket base so as to be oriented transversely to the first arch wire slot, each arch wire slot having an outer opening and a pair of side openings adapted to receive an arch wire therethrough; a ligation cover hingedly attached to the bracket base and movable between an open, non-ligating position relative to the first and second arch wire slots and a closed, ligating position in which the outer openings of the first and second arch wire slots are at least partially covered and occluded by the ligation cover, the first and second arch wire slots being open and completely non-occluded when the ligation cover is in the open, non-ligating position. 17. An orthodontic bracket comprising: a bracket base that includes first and second arch wire slots, each adapted to receive an arch wire therein; a ligation cover hingedly attached to the bracket base by at least one of an integral hinge or a film hinge, so that the bracket base and ligation cover form a single piece, such that the ligation cover is selectively rotatable about the integral hinge or film hinge between an open, non-ligating position relative to the first and second archwire slots and a closed, ligating position in which the first and second arch wire slots are at least partially occluded by the ligation cover, the first and second arch wire slots being open and completely non-occluded when the ligation cover is in the open, non-ligating position. 18. An orthodontic bracket comprising: a bracket base that includes first and second arch wire slots, each adapted to receive an arch wire therein; a ligation cover movable between an open, non-ligating position relative to the first and second arch wire slots and a closed, ligating position in which the first and second arch wire slots are at least partially occluded by the ligation cover, the first and second arch wire slots being open and completely non-occluded when the ligation cover is in the open, non-ligating position; and a third arch wire slot that is open and completely non-occluded when the ligation cover is in the open, non-ligating position and which remains open and non-occluded when the ligation cover is in the closed, ligating position. 19. An orthodontic bracket comprising: a bracket base that includes first, second and third arch wire slots, each having an outer opening and a pair of side openings adapted to receive an arch wire therethrough; a ligation cover hingedly attached to the bracket base and movable between an open, non-ligating position relative to the first, second and third arch wire slots and a closed, ligating position in which the outer openings of the first, second and third arch wire slots are at least partially occluded by the ligation cover, the first, second and third arch wire slots being open and completely non-occluded when the ligation cover is in the open, non-ligating position. 20. An orthodontic bracket comprising: a bracket base that includes first and second arch wire slots, each adapted to receive an arch wire therein; a ligation cover that is separate and completely detachable from the bracket base and movable between an open, non-ligating position relative to the first and second arch wire slots and a closed, ligating position in which the first and second arch wire slots are at least partially occluded by the ligation cover, the first and second arch wire slots being open and completely non-occluded when the ligation cover is in the open, non-ligating position; and a leash that loosely interconnects the ligation cover and the bracket base. 21. An orthodontic bracket comprising: a bracket base that includes first and second arch wire slots, each adapted to receive an arch wire therein; a ligation cover hingedly attached to the bracket base by a fiber hinge or an elastomeric adhesive interconnecting the ligation cover and bracket base, the ligation cover being movable between an open, non-ligating position relative to the first and second arch wire slots and a closed, ligating position in which the first and second arch wire slots are at least partially occluded by the ligation cover, the first and second arch wire slots being open and completely non-occluded when the ligation cover is in the open, non-ligating position.
