Electrical connectors for storage device

An electrical connector providing an interface for storage device, comprising:

• an insulated housing having a base portion and an integral tongue portion extending from a front face of the base portion along a first direction, the integral tongue portion defining a first side face parallel to the first direction and a second side face opposite to the first side face;
• a plurality of electrical contacts assembled to the insulated housing and lined along the first side face, each of said electrical contacts extending along the first direction for mating with a mating electrical connector;
• wherein said integral tongue portion having two ribs extending along the first direction from the front face of the base portion, said two ribs being disposed on the first side face of the integral tongue portion;
• wherein the integral tongue portion comprises a power segment for delivering power, a signal segment for delivering signal and a middle segment connecting the power segment and the signal segment, and the power segment and the signal segment could be compatible with an internal micro Serial ATA backplane connector except that the middle segment prevents insertion of the electrical connector into the internal micro Serial ATA backplane connector;
• wherein said two ribs divides the plurality of contacts into three groups in turn the first, the second and the third groups, the first group of contacts composing of two optional contacts used for delivering power, the second group of contacts composing of seven contacts used for delivering power, the third group of contacts composing of seven contacts being used for delivering signal;
• wherein the electrical connector further comprise a second plurality of electrical contacts assembled to the insulated housing, the second plurality of electrical contacts lined along the second side face, each of said second plurality of electrical contacts extending along the first direction to contact with said mating electrical connector;
• wherein the second plurality of electrical contacts composes of seven contacts and are aligned to the first group of contacts and the neighboring rib in a second direction perpendicular to the second side face.

An electrical connector assembly for connecting a storage device, comprising:

• a first electrical connector comprising:
• a first insulated housing defining an uninterrupted longitudinal slot in a front face, the slot having a first and a second inner side faces facing to each other, and the first and second inner side faces extending in a first direction perpendicular to the front face;
• a plurality of electrical contacts disposed in the insulated housing and lined along the first side face, each of said electrical contacts extending along the first direction;
• wherein the first inner side face of said slot defining two spaced grooves extending along the first direction from the front face;
• a second mating electrical connector comprising:
• a second insulated housing having a base portion and an uninterrupted longitudinal tongue portion extending from a front face of the base portion along a first direction for mating into the slot of the first insulated housing, the tongue portion defining a first side face parallel to the first direction and a second side face opposite to the first side face;
• a plurality of electrical contacts assembled to the insulated housing for mating with the electrical contacts of the first electrical connector,
• wherein said tongue portion having two spaced ribs extending along the first direction from the front face of the base portion for respectively mating into the grooves the first insulated housing;
• wherein the slot and the grooves are shaped compatible with an internal micro Serial ATA plug connector and the grooves prevents insertion of other Serial ATA cables;
• wherein the plurality of the contacts are divided into three groups in turn the first, the second and the third groups, the first group of contacts composing of two optional contacts used for delivering power, the second group of contacts composing of seven contacts used for delivering power, the third group of contacts composing of seven contacts being used for delivering signal;
• wherein the electrical connector assembly further comprises a second plurality of electrical contacts assembled to the insulated housing and lined along the second side face, each of said second plurality of electrical contacts extending along the first direction for mating with said second electrical connector;
• wherein the second plurality of electrical contacts composes of seven contacts and are aligned to the first group of contacts and the neighboring groove in a second direction perpendicular to the second side face.
