A pair of tabs on the top rear of the front shell engages with a pair of corresponding first recesses on a top front of the rear shell and a pair of corresponding second recesses defined in the insulative housing. A plurality of latching fingers extending from inserting plates of the front shell engages with corresponding apertures in the rear shell.

Abstract: An electrical connector comprises an insulative housing, a number of conductive contacts, a shell and a rear cover. Receiving slots are disposed in the insulative housing for receiving the conductive contacts. Positioning grooves are defined at a rear lower side of the insulative housing, and a number of bumps are disposed on opposite inside surfaces thereof to interferingly retain soldering sections of the conductive contacts. A stabilization device, stamped and formed from a bottom forward surface of the shell, aids in providing a stable mounting of the electrical connector on the printed circuit board. Thus the electrical connector is prevented from slanting forward on its mounting, assuring proper operation.
