Electrcial connector and manufacturing method of the same

A manufacturing method of an electrical connector comprising:

• step 1:
• holding a row of second contacts and a shielding plate in a pre-position, the second contacts comprise contacting sections;
• step 2:
• forming an insulative sub-housing on the second contacts and the shielding plate via a first insert-molding process, wherein the sub-housing comprises an upper face and a lower face, the contacting sections of the second contacts expose to the lower face, the sub-housing defines a projecting are on a front of the upper face and a plurality of ribs on a middle of the upper face;
• step 3:
• disposed a row of first contacts on the upper face of the sub-housing, the first contacts comprises contacting sections, soldering sections and connecting sections jointing the contacting sections and the soldering sections, wherein the contacting sections are supported on a top of the projecting area and the connecting sections are positioned between ribs to limit the connecting sections in a left and right direction;
• step 4:
• forming an insulative coat on the first contacts and the sub-housing via a second insert-molding process, wherein the insulative coat completes the lower face of the sub-housing, contacting sections of the first contacts exposes to an upper face of the insulative coat and the shielding plate are located between the first contacts and the second contacts, therefore forming a terminal module which comprising a base and a mating tongue extending from the base.

An electrical connector comprising:

• a terminal module including an insulative housing, and a row of first contacts, a row of second contacts and a shielding plate located embedded in the insulating housing;
• the insulating housing including a base and a mating tongue forwardly extending from the base in a front-to-back direction, the mating tongue defines an first surface and a second surface opposite to each other in a vertical direction perpendicular to said front-to-back direction;
• each of the first contacts including a first contacting section exposing upon the first surface;
• each of the second contacts including a second contacting section exposed upon the second surface, a second solder leg and a second connecting portion connecting with the second contacting section and the second solder leg;
• the shielding plate disposed between the upper and lower contacts in the vertical direction, and including a pair of side latching edges in a transverse direction perpendicular to both said front-to-back direction and said vertical direction;
• wherein
• the insulative housing is formed with at least an insulative sub-housing and an insulative coat, and said sub-housing is integrally formed with the second contacts and the shielding plate via an initial step insert-molding process while said coat is integrally formed with the first contacts via a successive step insert-molding process so as to have the first surface essentially fully formed by the coat while the second surface essentially fully formed by the sub-housing except along a peripheral region thereof;
• wherein the sub-housing defines a projecting area and a plurality of front ribs thereof, the second contacting sections are supported on the projecting area and the second connecting sections are positioned and limited between adjacent front ribs in a left and right direction.
