Referring to fig. 1 to 7, an electrical receptacle connector according to the present utility model includes a terminal module 1 and a metal housing 2 surrounding/sleeved around the terminal module 1. The metal housing 2 and the terminal module 1 together define an annular mating space 101 and form an insertion opening 102 at one end. The socket electric connector is of an USB Type C architecture, wherein four pairs of high-speed differential pair terminals are not arranged. The socket electrical connector of the utility model can be matched with a full Pin plug connector with 24 terminals for transmitting USB2.0 signals.

The terminal module 1 includes an insulator 11 formed by injection molding an insulating material and a plurality of terminals 12 incorporated in the insulator 11. The insulator 11 includes an insulating base 111 and a filling portion 112. The insulating base 111 is formed with a base 13 and a tongue portion 14 formed by extending the base 13 forward. The tongue 14 includes a tongue base 141 formed by extending the base 13 forward and a tongue end 142 formed by extending the tongue base 141 further forward. The thickness of the tongue base 141 is greater than the thickness of the tongue end 142 in the up-down direction (i.e., the thickness direction of the tongue 14); the width of the tongue base 141 is greater than the width of the tongue end 142 in the left-right direction (i.e., the width direction of the tongue 14).

Referring to fig. 2 to 7 in combination, each of the terminals 12 includes a fixing section 121 embedded in the base 13, an extending section 122 integrally fixed with the tongue 14, and a mating section 123 protruding rearward from the base 13. The filling portion 112 fills the gap formed between the tongue portion 14 and the extension 122, and forms the tongue plate portion 110 together with the tongue portion 14. The extension section 122 of each terminal 12 is formed with a contact section 1221 exposing the tongue plate 110, and the contact sections 1221 are arranged in two rows on the upper surface 1101 and the lower surface 1102 of the tongue plate 110. The contact section 1221 located on the upper surface of the tongue plate 110 corresponds to the contact section 1221 located on the lower surface of the tongue plate 110 in the thickness direction of the tongue plate 110, and is preferably designed as follows: each contact section 1221 located on the upper surface 1101 of the flap portion 110 overlaps one by one with the projection of each contact section 1221 located on the lower surface 1102 of the flap portion 110 in the thickness direction of the flap portion 110. The terminal architecture arrangement mode accords with the USB Type C. In addition, the abutting sections 123 of all the terminals are arranged in a row at the rear end of the insulator 11.

Referring mainly to fig. 4 in conjunction with fig. 2 to 5, the terminal section within the width L2 as seen by two dash-dot lines is the fixing section 121. As shown in fig. 4, a row of terminals 12 of the contact section 1221 on the upper surface (not numbered) of the tongue plate 110 are, from left to right, a terminal B1, a terminal B2, a terminal B3, a terminal B4, a terminal B5, a terminal B6, a terminal B7, and a terminal B8 in this order. A row of terminals 12 of the contact section 1221 on the lower surface of the tongue plate 110 are, from left to right, a terminal A1, a terminal A2, a terminal A3, a terminal A4, a terminal A5, a terminal A6, a terminal A7, and a terminal A8 in this order. Among them, the terminals A1, B1, A8, and B8 are ground terminals. The terminals A2, B2, A7, and B7 are power supply terminals. Terminals A3-A6 and terminals B3-B6 are signal terminals. Two terminal vacancies are reserved between the terminal A1 and the terminal A2; two terminal vacancies are reserved between the terminal B1 and the terminal B2; two terminal vacancies are reserved between the terminal A7 and the terminal A8; two terminal vacancies are reserved between terminal B7 and terminal B8. There are also two intermediate plates 10, one of which is sandwiched between the contact sections 1221 of the pair of terminals A1 and B1, and the other of which is sandwiched between the contact sections 1221 of the pair of terminals A8 and B8.

As shown in fig. 5 to 7, in the thickness direction of the tongue plate 110, the front end of the extension section 122 of any pair of overlapped terminals 12 (non-ground terminals) projected by the contact section 1221 is formed with a front molding portion 1222, and the two front molding portions 1222 are arranged in a staggered manner, and the upper surface and the lower surface of each front molding portion 1222 are exposed outside the tongue portion 14 in the thickness direction of the tongue plate 110, and the front end edge of the front molding portion 1222 is embedded in the insulator 11. The rear end of the extension section 122 of any pair of the terminals 12 (non-ground terminals) overlapped by the contact section 1221 is projected in the thickness direction of the tongue plate portion 110 to form a rear embossed portion 1223, and the rear embossed portion 1223 is formed at a position where the corresponding extension section 122 is joined to the tongue base 141 (that is, the rear embossed portion 1223 is formed at a partial position of the terminal section within the width L1 as seen by two chain lines in fig. 4). The two rear molding portions 1223 are disposed in a staggered manner, and the upper surface and the lower surface of each rear molding portion 1223 are exposed outside the tongue base 141 along the thickness direction of the tongue plate 110.

The filler part 112 is coupled to the filler tongue 14 only, and includes a rear portion 1121 coupled to the filler tongue base 141 and a front portion 1122 coupled to the filler tongue end 142. In the production of the socket connector of the present utility model, two rows of terminals 12 (A1-A8, B1-B8) and a middle board member 10 are positioned by a mold to form an injection cavity (not shown), wherein the positioning of the front molding portion 1222 and the positioning of the rear molding portion 1223 are performed by a mold core/ejector pin along the up-down direction; then, the injection molding cavity is filled with molten plastic and then cooled to form an insulator 11, and the front end edge of the front mold pressing part 1222 is buried in the insulator 11; the molten plastic is then filled into the gaps of the tongue portion 14 of the insulator 11 and cooled to form the filling portion 112, and the filling portion 112 may be formed by solidifying the filled glue. By adopting the design scheme of the utility model, the manufacturing process of the socket electric connector can be simplified.
