Claim 9

The cable end connector assembly as claimed in claim 7 , wherein the spacer defines a plurality of through holes therein, the tail portions of the contacts protrude through the through holes and are soldered with the conductive cores, respectively.

Claim 10

The cable end connector assembly as claimed in claim 1 , wherein the rear portion of the housing comprises an upper wall, a lower wall, and a pair of opposite sidewalls, the cover comprises an upper wall, a lower wall, and a pair of lateral walls, the through hole is a plurality of through holes defined in the upper and the lower walls of the rear portion, and the projection is a plurality of projections formed on inner surfaces of the upper and the lower walls of the cover, the projections are respectively received in the holes.

Claim 11

The cable end connector assembly as claimed in claim 9 , wherein the front portion of the housing is formed by an upper wall, a lower wall, and a pair of sidewalls, and the front portion defines an L-shaped receiving space adapted for receiving a mating portion of the complementary electrical connector therein.

Claim 12

The cable end connector assembly as claimed in claim 10 , wherein the passageways are defined through the lower wall of the front portion of the housing in the front-to-rear direction.

Claim 13

The cable end connector assembly as claimed in claim 10 , wherein an outer surface of the upper wall of the rear portion is higher than that of the upper wall of the front portion, an outer surface of the lower wall of the rear portion is lower than that of the lower wall of the front portion.

Claim 14

The cable end connector assembly as claimed in claim 12 , wherein a pair of outstanding portions is formed on the inner surfaces of the upper and the lower walls of the cover and adjacent to a front face of the cover and engage with the upper and lower walls of the rear portion of the housing for preventing the rear portion from moving along a front-to-rear direction of the housing.

Claim 15

A cable end connector assembly comprising: a housing assembly for receiving a complementary connector therein, including a dielectric housing and a spacer housing attached to the housing, said dielectric housing defining a cavity extending in a horizontal plane; a plurality of contacts retained by at least one of said dielectric housing and said spacer housing, each of said contacts including a mating portion extending forwardly into the cavity and a solder portion extending rearwardly out the spacer housing; a cable including a plurality of conductive cores soldered upon the corresponding solder portions of the contacts, respectively; a cover over-molded with a rear portion of the housing assembly and a front portion of the cable; and a plurality of through holes being formed in the rear portion of said housing assembly, and material of said cover extending in a direction perpendicular to said horizontal plane and into said plurality of through holes and intercepting the rear portion of the housing assembly for efficiently resisting relative horizontal movement between the cover and the housing assembly along said plane; wherein said housing assembly defines a receiving slot in the rear portion under a condition that said receiving slot is filled with the material of the cover and communicates with said through holes.

Claim 16
