Abstract

A card edge connector includes an insulative housing with a pair of opposite side walls extending along a longitudinal direction with a central slot therebetween in the transverse direction perpendicular to the longitudinal direction. A pair of towers are located at two opposite ends of the housing in the longitudinal direction. The housing is essentially obliquely mounted upon a printed circuit board. Each tower has a lower/first part and an upper/second part in the vertical direction perpendicular to the longitudinal direction and the transverse direction. The width dimension in the transverse direction of the upper part is smaller than that of the lower part.

First claim

What is claimed is:

1. A card edge connector for mounting to a printed circuit board, comprising:
an insulative housing including a pair of side walls extending along a longitudinal direction with a central slot therebeween in a transverse direction perpendicular to said longitudinal direction;
said housing forming a mounting face for mounting toward the printed circuit board wherein the housing extends in a plane oblique to said mounting face;
a pair of towers located at two ends of the housing in said longitudinal direction, each of said towers including a lower part and an upper part extending in a vertical direction perpendicular to both said longitudinal direction and said transverse direction; and
a pair of ejectors rotatably disposed in the corresponding towers, respectively; wherein
a width of the upper part along the transverse direction is dimensioned smaller than that of the lower part for densely arranging, on the printed circuit board, two card edge connectors in a front-to-back direction which is perpendicular to the longitudinal direction while being oblique to both said vertical direction and said transverse direction;
wherein the upper part has a recess in a downward face for receiving a bottom region of the lower part of the tower of another card edge connector therebehind in said front-to-back direction.

2. The card edge connector as claimed in claim 1 , further including a plurality of terminals by two sides of the central slot, wherein the side walls includes an upper side wall and a lower side wall with the central slot therebetween, and the terminals in the upper side wall are wider than those in the lower side wall in the transverse direction.

3. The card edge connector as claimed in claim 2 , further including a cover to shield mounting sections of the corresponding terminals.

4. The card edge connector as claimed in claim 3 , wherein said cover has a similar dimension with the housing in the longitudinal direction, and includes recesses in an upper surface at two ends thereof corresponding to the towers.

5. The card edge connector as claimed in claim 3 , wherein said cover is shorter than the housing without reaching two opposite positions corresponding to the towers.

6. The card edge connector as claimed in claim 1 , wherein said ejector includes a handler at a top end having a width similar to that of the upper part.

7. An electrical connector assembly comprising:
a printed circuit board;
a front connector and a rear connector same with each other and densely arranged upon the printed circuit board in a front-to-back direction, each of said front connector and said rear connector including:
an insulative housing including a pair of side walls extending along a longitudinal direction with a central slot therebeween in a transverse direction perpendicular to said longitudinal direction;
said housing forming a mounting face for mounting toward the printed circuit board wherein the housing extends in a plane oblique to said mounting face;
a pair of towers located at two ends of the housing in said longitudinal direction, each of said towers including a lower part and an upper part extending in a vertical direction perpendicular to both said longitudinal direction and said transverse direction; and
a pair of ejectors rotatably disposed in the corresponding towers, respectively; wherein
a width of the upper part along the transverse direction is dimensioned smaller than that of the lower part to form therein a recess so that the recess formed in the upper part of the tower of the front connector receives a bottom region of the lower part of the rear connector; wherein
said front-to-back direction is perpendicular to the longitudinal direction while being oblique to both said vertical direction and said transverse direction.

8. The electrical connector assembly as claimed in claim 7 , further including a plurality of terminals by two sides of the central slot, wherein the side walls includes an upper side wall and a lower side wall with the central slot therebetween, and the terminals in the upper side wall are wider than those in the lower side wall in the transverse direction.

9. The electrical connector assembly as claimed in claim 8 , further including a cover to shield mounting sections of the corresponding terminals.

10. The electrical connector assembly as claimed in claim 9 , wherein said cover has a similar dimension with the housing in the longitudinal direction, and includes recesses in an upper surface at two ends thereof corresponding to the towers.

11. The card edge connector as claimed in claim 9 , wherein said cover is shorter than the housing without reaching two opposite positions corresponding to the towers.

12. The card edge connector as claimed in claim 7 , wherein said ejector includes a handler at a top end having a width similar to that of the upper part.

13. A card edge connector for mounting to a printed circuit board, comprising:
an insulative housing including a pair of side walls extending along a longitudinal direction with a central slot therebeween in a transverse direction perpendicular to said longitudinal direction,
said housing forming a mounting face for mounting toward the printed circuit board wherein the housing extends in a plane oblique to said mounting face;
a pair of towers located at two ends of the housing in said longitudinal direction, each of said towers including a lower part and an upper part extending in a vertical direction perpendicular to both said longitudinal direction and said transverse direction;
a pair of ejectors rotatably disposed in the corresponding towers, respectively; and
a plurality of terminals by two sides of the central slot;
wherein the side walls includes an upper side wall and a lower side wall with the central slot therebetween, and the terminals in the upper side wall are wider than those in the lower side wall in the transverse direction;
wherein each of the terminals in the upper side wall has a base from which a retention post and a contacting section commonly extends in a spaced manner in the transverse direction while each of the terminals in the lower side wall has a barbed base from which a contacting section extends.
