Abstract

An electrical connector comprises an insulative housing, a shield, a number of terminals, a shielding blade and a pair of guide posts. The housing includes a cover and a base separately manufactured by injection molding. Thus, a height of a corresponding mold for forming the cover and the base is decreased thereby promoting the free flow of molten plastic and enhancing the strength of the housing especially terminal passageways thereof. In assembly, the shield, the cover and the base are secured together by riveting the guide posts. The blade is disposed in the cover and the base for eliminating cross talk between the terminals. The blade electrically contacts the shield which is conductively connected to the guide posts.

Claims

1. An electrical connector mounted on a circuit board, comprising:

an insulative housing including a cover and a base, each of the cover and the base defining a plurality of terminal passageways, the cover defining a mounting hole therethrough, the base defining a mounting opening therethrough aligned with the mounting hole, the base and the cover being separately injection molded and mounted together to form the housing;

a guide post extending through the mounting opening of the base and the mounting hole of the cover to bond the base and the cover; and

a plurality of terminals retained in corresponding passageways of the base and the cover;

wherein a shielding blade is disposed in the housing for eliminating cross talk between the terminals;

further comprising a shield attached to the housing, and wherein a spring arm extends from a side edge of the blade for electrically contacting the shield;

wherein the guide post is conductively connected to the shield and the blade.

2. The electrical connector as claimed in claim 1, wherein an elongate mating portion projects upward from a top face of the cover and forms a receiving slot in a central portion thereof, and wherein an elongate projection projects from a bottom of the slot.

3. The electrical connector as claimed in claim 1 further comprising a shield attached to the housing.

4. The electrical connector as claimed in claim 1, wherein the blade includes cutouts for engaging the cover and the base, respectively.

5. An electrical connector mounted on a circuit board, comprising:

an insulative housing including a cover and a base aligned and stacked with each other, the base defining a slot in a central portion, the cover defining an elongated projection with a plurality of slits therein, a first stop portion being positioned between every two adjacent slits, said slits being aligned with the slot in a vertical direction;

a grounding blade defining an upper portion received within the slits, and a lower portion received within the slot, said upper portion defining a plurality of first cutouts, and said lower portion defining a plurality of second cutouts;

plurality of second stop portions formed in the slot of the base and received within the corresponding second cutouts; and

said first stop portion of the cover received within the corresponding first cutout;

wherein said blade further includes a spring arm at one end thereof, and the cover defines an aperture adjacent one end thereof so that the spring arm extends through said aperture to engage a shield enclosing said cover.
