Electrical connector having printed substrates therein electrically contacting conductive contacts thereof by solderless

Claim 1

An electrical connector comprising: a first housing portion defining a plurality of passageways; a plurality of substrates respectively received in the passageways of the first housing portion, each substrate having a plurality of first conductive pads near a first edge thereof, a plurality of second conductive pads near a second edge thereof and a plurality of conductive traces connecting the first conductive pads to the second conductive pads, at least parts of the second edge extending out of the first housing with the second conductive pads being exposed out of the first housing portion; a second housing portion defining a plurality of channels; and a plurality of signal contacts and a plurality of grounding terminals, each channel of the second housing portion fixedly receiving at least one signal contact and a grounding terminal confronting the at least one signal contact; the first housing portion engaging with the second housing portion and the second edges of the substrates being inserted into corresponding channels of the second housing portion so as to be sandwiched between corresponding signal contacts and grounding terminals in the channels, the signal contacts and the grounding terminals moveably and electrically contacting corresponding second conductive pads in the channels; wherein the first housing portion has a front surface adapted for mating with a mating connector, a rear surface and a lower surface orthogonal to the rear surface, the substrates being inserted in the passageways of the first housing portion from the rear surface toward the front surface with parts thereof extending out of the lower surface; wherein each grounding terminal has at least one contacting arm and each signal contact has at least one contacting portion sandwiching the second edge of the printed substrate therebetween, the contacting arm of the grounding terminal being stronger than the contacting portion of the signal contact such that the second edge of the substrate is pushed by the contacting arm toward the contacting portion; wherein the first and the second housing portions each provide a row of blocks and a row of notches, the blocks of one of the first and the second housing portions being fixedly received in corresponding notches of the other of the first and the second housing portions, thereby joining the first and the second housing portions together; wherein one of the first and the second housing portions provides at least one guiding rib and the other of the first and the second housing portions provides at least one guiding track, the at least one guiding rib engaging with the at least one guiding track before the engagement of the blocks with the notches of the first and the second housing portions.
