A pair of indentations 253, such as the side edges of the upper and lower insulators 236, 246, project from the edges, particularly the side edges 2561 of the shield panel 256. The projections 241, 251 are located substantially at the intermediate position of the pair of notches 253. It can also be seen from the sixth figure that the front end of the longer grounding terminal or the power terminal located on both sides is substantially aligned with the front hole 259, and the shielding plate 256 is provided with a thin section, and the front end of the shorter signal terminal just corresponds to the thin shape. Area.

Then, the two grounding pieces 290 are respectively assembled from the side to the two sides of the upper and lower modules fixed together. Referring to the seventh and eighth figures, the grounding piece 290 is attached to the thickened portions 2363 and 2463. The fixing portion 292 of the grounding piece 290 is received in the notch 253 of the shielding plate 256. Each of the fixing portions 292 includes a first fixing portion 2921 and a second fixing portion 2922 . The first fixing portion 2921 has a notch 2923 at the end thereof, and the first fixing portion 2921 is longer than the second fixing portion 2922 . The first and second fixing portions 2921 and 2922 at both ends of each grounding piece 290 are arranged in a front-rear arrangement, that is, the first fixing portion 2921 at one end is located on the front side, and the first fixing portion 2921 at the other end is located at the rear side, and two grounding pieces 290 are provided. The first and second fixing portions 2921, 2922 are also arranged in a front-rear exchange. Located on the same side (for example, the right side), the first fixing portion 2921 of the upper grounding piece 290a is located at the rear, and the first fixing portion 2921 of the lower grounding piece 290b is located at the front. The longer first fixing portion 2921 is fixedly received in the notch 253, and the second fixing portion 2922 is at a certain distance from the shielding plate 256. Thus, a certain gap 2924 is formed between the fixing portions of the two grounding pieces 290, in the second time. In the case of injection molding, an insulating material can be poured therein to achieve a better fixing effect. The protruding portions 241 and 251 are located between the first and second fixing portions 2921 and 2922. The lower module 242 extends downwardly out of the mounting post 283.

Then, the filling portion 260 is injection molded on the outer side of the main body portion 230 by a second injection molding process, thereby forming a complete terminal module 220 as shown in the ninth to twelfth drawings. The filling portion 260 fills the first channel 238, 248, the first through holes 240, 250 and the lateral grooves 280, 282, the intermediate port 257 and the pair of front holes 259 and the lateral ports 254, and also covers the main body portion 230. The two side edges and the front edge only expose the latch side 258, as shown in FIG. Of course, in other embodiments, as shown in the tenth figure, the entire side 252 of the shield panel 256 may also slightly protrude from the side of the butt tongue 294, but will not exceed the latch side 258. The lateral side of the shielding plate 256 is completely exposed along the abutting tongue 294. The filling portion 260 also forms a thickened step portion 2941 at the corresponding grounding piece 290. The grounding piece 290 covers the upper and lower surfaces of the step portion 2941. Since the grounding piece 290 is assembled first before the second injection molding, both ends of the grounding piece 290 are embedded in the filling portion 260, and only partially exposed on the surface of the butting tongue 294 to provide abutment with the elastic piece of the mating plug connector. . The contacts 233, 243 are exposed on opposite surfaces of the butt tongue 294. The filling portion 260 is filled in the inner and outer sides of the upper and lower modules 232 and 242 and the grounding piece 290 to form the abutting tongue 294 and a partially exposed grounding piece 290. The front edge of the grounding piece 290 is provided with a notch 293. The filling portion 260 is filled in the notch 293, and the grounding piece 290 can be better fixed in the socket connector, as shown in the seventh and ninth figures. The complete terminal module 220 includes an upper terminal 234, a lower terminal 244, a shielding plate 256 disposed in the abutting tongue 294, and a grounding piece 290. The abutting tongue 294 defines two opposite surfaces, and the upper and lower terminals 234 are defined. And 244 respectively include contact portions 233 and 243 arranged on two opposite surfaces of the butt tongue 294 and pins 237 and 247 extending from the terminal module 220. The grounding lug 290 is also exposed on the opposite surfaces of the mating tongue 294 and its two ends are embedded in the terminal modules 232, 242 to form a smooth surface. It can be understood that the grounding piece 290 is assembled first and then embedded at both ends of the terminal module by the injection molding method, so that there is a smooth plane and the product precision is high.

It can be understood that the filling portion 260 has a certain interface line with the outer surface of the main body portion 230. If the two are formed of materials of different colors, the interface line is obvious. The interface line 295 shown in the ninth diagram is the boundary between the filling portion 260 and the upper insulator 236. The filling portion 260 shares the same upper surface as the insulator 236, and the lower insulator 246 shares the same lower surface. It is clear that the connection of the upper terminal 234 The front end 2331 of the contact portion 233 is fixed in the filling portion 260 after the second injection molding (as shown in FIG. 13), and the other portion of the contact portion 233 remains on the upper insulator 236 during the first injection molding. surface. The structure of the contact portion 243 of the lower terminal 244 is the same and will not be described again.

Referring to the eleventh and twelfth drawings, before the second injection molding, the first channels 238, 248 are not aligned with the contact portions 233, 243 in the vertical direction, but are offset by a certain distance, which is optimal. In the embodiment, the two have no overlapping portions at all. After the second injection molding, the first channel is filled with the material of the filling portion 260, as shown in Fig. 12. The transverse grooves 280, 282 are used to enhance during the second molding process, or for integration considerations. The front ends of the upper and lower insulators 236, 246 terminate at the front ends 2331, 2431 of the contacts 233, 243 such that only the front ends 2331, 2431 of the contacts 233, 243 are exposed outside of the insulators 236, 246.

Referring to the thirteenth and fourteenth views, the front ends 2331, 2431 of the contact portions 233, 243 are relatively inclined and buried in the filling body 260, which is different from the stacked socket connectors. On the other hand, since the filling portion 260 is filled in each of the corners of the main body portion 230 in three dimensional directions, including the inner and outer structures, the entire terminal module 220 is a completely closed structure, including the butt tongue 294 on the front side, The step portion 2941 of the grounding piece 290 and the rear base portion 296 located behind the grounding piece 290 are attached, and the abutting tongue 294 extends forward from the rear base portion 296 as shown in FIG. As above, this is the overmolding injection molding method. First, the upper module 232 and the lower module 242 are formed for the first time, and then the second injection molding is completed on the basis of the upper and lower modules 232 and 242. Group 220, as such, a relatively complete assembled structure provides a reinforced connector structure. In other embodiments, the insulator and the terminals of the upper and lower modules 232 and 242 can also be completed by the assembly method. The main body portion 230 and the filling portion 260 of the terminal module 220 are completed by one injection molding. Referring to the second figure, the filling portion 260 includes a butt tongue outer frame 2601, a thickening frame 2602, and a vertical base frame 2603.

After the first injection molding, only the very short front ends 2331, 2431 of the contacts 233, 243 are exposed outside the upper and lower insulators 236, 246, and in the second injection molding process, such a short contact front end 2331 2431 will not tilt. It can be understood that if the interface line 295 is away from the front ends 2331, 2431 of the contact portions 233, 243, in the second injection molding process, in the high pressure plastic flow In the following, the front ends 2331, 2431 of the contact portions 233, 243 are highly likely to be bent. The upper and lower modules 232 and 242 of the present embodiment are completed by one injection molding, and the terminal module 220 is completed by one injection molding method. Therefore, the terminal module 220 is manufactured for the secondary molding method. In other embodiments, the insulator and the terminal of the upper and lower modules can also be completed by the assembly method, and the main body portion 230 and the filling portion 260 of the terminal module 220 are completed by one injection molding.
