Electrical connector having retention system for mounting onto a printed circuit board

Claim 2

An electrical connector comprising: an insulative housing adapted for being mounted to an edge of a printed circuit board, the housing having an elongated body portion, a mating portion projecting forwardly from the body portion adapted for engaging with a complementary connector and defining a plurality of recesses therein, a pair of guide portions positioned on both ends of the body portion, and a back portion extending rearwardly from the body portion, a post projecting downwardly from each of the guide portions adapted for extending through holes defined in the printed circuit board, a pole projecting downwardly from the back portion adapted for retentively engaging in a hole of the printed circuit board, said insulative housing defining apertures being located in front of and in line with the posts and pole, respectively, each aperture having a size larger than a corresponding post or pole; and a plurality of contacts secured to the housing, each contact having a contact portion received in a corresponding recess; wherein the guide portions each defines a channel adapted for guiding the complementary connector to mate with the electrical connector, and a groove adapted for fittingly receiving a screw, the groove being opposite to the channel; wherein the pole has a pair of wings located on opposite sides thereof.

Claim 3

The electrical connector as described in claim 1 , wherein each post is positioned at an inner side of a corresponding guide portion.

Claim 4

An electrical connector comprising: an insulative housing mounted to an edge of a printed circuit board, the housing having an elongated body portion, a mating portion projecting forwardly from the body portion adapted for engaging with a complementary connector and defining a plurality of recesses therein, a pair of guide portions positioned on both ends of the body portion, and a back portion extending rearwardly from the body portion, a post projecting downwardly from each of the guide portions extending through holes defined in the printed circuit board, a pole projecting downwardly from the back portion retentively engaging in a hole of the printed circuit board, each guide portion having a forwardly extending channel adapted for guiding the complementary connector to mate with the electrical connector, and a groove opposite the channel, a screw being fittingly received in the groove and through the printed circuit board, and a nut threadedly engaging the screw at a bottom of the printed circuit board; and a plurality of contacts secured to the housing, each contact having a contact portion received in a corresponding recess; wherein front-to-rear extending apertures are formed in the housing respectively in front of and in line with the posts and the pole, each aperture having a dimension larger than a corresponding post or pole; wherein the grooves each are U-shaped and have an arced front end; wherein the pole has a pair of wings on opposite side thereof.

Claim 5

An electrical connector comprising: an insulative housing mounted to an edge of a printed circuit board, the housing having an elongated body portion, a mating portion projecting forwardly from the body portion adapted for engaging with a complementary connector and defining a plurality of recesses therein, a pair of guide portions positioned on both ends of the body portion, and a back portion extending rearwardly from the body portion, a post projecting downwardly from each of the guide portions extending through holes defined in the printed circuit board, a pole projecting downwardly from the back portion retentively engaging in a hole of the printed circuit board, each guide portion having a forwardly extending channel adapted for guiding the complementary connector to mate with the electrical connector, and a groove opposite the channel, a screw being fittingly received in the groove and through the printed circuit board, and a nut threadedly engaging the screw at a bottom of the printed circuit board; and a plurality of contacts secured to the housing, each contact having a contact portion received in a corresponding recess; wherein front-to-rear extending apertures are formed in the housing respectively in front of and in line with the posts and the pole, each aperture having a dimension larger than a corresponding post or pole; wherein the grooves each are U-shaped and have an arced front end; wherein the pole has a pair of wings on opposite side thereof.

Claim 6

An electrical connector assembly comprising: a printed circuit board defining an upper surface thereon; an insulative housing defining a bottom face and a step around a rear portion thereof, a higher horizontal surface of said housing being defined on said step, a front edge portion of the printed circuit board received in the step with the higher surface of the housing seated upon the upper surface of the printed circuit board; a plurality of terminals received in the housing; a post integrally formed with the housing by injection molding and downwardly extending from the higher surface of the housing; and an aperture formed in the housing, said aperture being spaced from and in aligned with said post in a front-to-back direction and dimensioned to be large enough to expose the whole post in said front-to-back direction; wherein said aperture does not extend downwardly through said bottom face.

Claim 7

An electrical connector assembly comprising: a printed circuit board defining an upper surface thereon; an insulative housing defining a bottom face and a step around a rear portion thereof, a higher horizontal surface of said housing being defined on said step, a front edge portion of the printed circuit board received in the step with the higher surface of the housing seated upon the upper surface of the printed circuit board; a plurality of terminals received in the housing; a post integrally formed with the housing by injection molding and downwardly extending from the higher surface of the housing; and an aperture formed in the housing, said aperture being spaced from and in aligned with said post in a front-to-back direction and dimensioned to be large enough to expose the whole post in said front-to-back direction; wherein said aperture does not extend downwardly through said bottom face.
