In fact, the support frame 1021 may be formed by pouring an insulating material outside the terminal members 1022, instead of being a separate member.

The terminal component 1022 includes a differential pair of female terminals and a female terminal ground terminal 10222 alternately arranged in sequence, the differential pair of female terminals includes two female terminal signal terminals 10221, and the female terminal signal terminals 10221, the female terminal signal terminals 10221 and the female terminal ground terminal 10222 are arranged at intervals. During processing, the terminal part 1022 is formed by integral stamping, and the adjacent terminals (including the female terminal signal terminal 10221 and the female terminal ground terminal 10222) are connected by residual materials, and the residual materials are removed after injection molding. The female signal terminal 10221 and the female ground terminal 10222 are bent terminals such that the female connector 100 forms a bent female.

The structure of the female signal terminal 10221 is shown in fig. 6, the female signal terminal 10221 has a signal spring 102211 at the mating end 104 of the terminal module 102, and the signal spring 102211 itself has a certain bending and can swing elastically, when in use, the signal pin plug end 2021 is inserted to one side of the signal spring 102211 and presses against the signal spring 102211, so that the signal spring 102211 and the signal pin plug end 2021 can make good contact with each other, and signal conduction is realized. The female signal terminal 10221 has a mounting terminal at the mounting end 103 of the terminal module 102, where the mounting terminal is a fish eye, and in other embodiments, the mounting terminal may be a pin-shaped or column-shaped terminal soldered to a printed circuit board.

The structure of the female ground terminal 10222 is shown in fig. 4 and fig. 15, the female ground terminal 10222 has a ground spring 102221 at the mating end 104 of the terminal module 102, the ground spring 102221 itself has a certain bending and can swing elastically, when in use, the ground pin insertion end 2031 is inserted into a channel formed by the ground spring 102221 and the convex hull 10232, and is clamped by the ground spring 102221 and the convex hull 10232, so as to realize ground conduction and form a signal shielding. As shown in fig. 4, the female ground terminal 10222 is divided into two types, one is the middle ground terminal 10222a, the other is the side ground terminal 10222b, and the front end of the side ground terminal 10222b is not provided with the ground spring 102221. In practice, side ground terminal 10222b may be provided on only one side, on both sides, or may not be provided. As shown in fig. 5, the signal dome 102211 and the ground dome 102221 have a structure, in which the signal dome 102211 includes a signal dome extension 1022111 extending forward, a signal dome turning portion 1022112 at the front end, and a signal dome inclined portion 1022113, and the signal dome inclined portion 1022113 extends obliquely. The ground spring 102221 includes a ground spring extension 1022211 extending forward, a ground spring turn portion 1022212 at the front end, and a ground spring inclined portion 1022213, where the ground spring inclined portion 1022213 extends obliquely.

As shown in fig. 4, the grounding spring 102221 has a bifurcated structure. The female ground terminal 10222 has a mounting terminal at the mounting end 103 of the terminal module 102, where the mounting terminal is a fish eye.

The structure of the shielding plate 1023 is as described in fig. 2, fig. 7, fig. 8, fig. 9 and fig. 10, the shielding plate 1023 includes a main body 10231, the main body 10231 is a complete plate, a convex bump 10232 is arranged on the front end (the end facing the male connector 200 in use) of the main body 10231, and the number of convex bumps 10232 is consistent with the number of grounding elastic pieces 102221 in the same terminal module 102 and corresponds to each other in the thickness direction of the terminal module 102. The convex protrusions 10232 are disposed protruding from the main body portion 10231 in the direction of the grounding elastic sheet 102221, and the convex protrusions 10232 are used for cooperating with the grounding elastic sheet 102221 to form a channel for inserting the grounding pin insertion end 2031. As can be seen in the enlarged view of fig. 8, the front end of the convex hull 10232 is a guiding ramp, here a slanted plane 10236, the slanted plane 10236 extending obliquely from the front to the back and in the direction of the grounding spring 102221. The inclined plane 10236 is preferably inclined at 45 ° in this case, and in other embodiments, the inclined angle may be changed according to actual conditions.

The reason why the inclined plane 10236 is provided here is: in the prior art, the front end of the convex hull 10232 is planar, the grounding pin insertion end 2031 can enter a channel between the convex hull 10232 and the grounding elastic sheet 102221, and is guided by the inclined surface of the front end of the grounding elastic sheet 102221, but because the grounding elastic sheet 102221 is a sheet structure with a small width, the overall strength is low, after the grounding elastic sheet 102221 is pressed by the grounding pin insertion end 2031 for a long time, the grounding elastic sheet 102221 is inclined, the grounding elastic sheet 102221 cannot be matched with the convex hull 10232 to clamp the grounding pin insertion end 2031, and the grounding shielding effect is poor. In this embodiment, the front end of the convex hull 10232 is designed as an inclined plane 10236, and the inclined plane 10236 is used to cooperate with the ground pin plug end 2031 to guide the ground pin plug end 2031 into the channel. The convex hulls 10232 are positioned on the shielding plate 1023, the whole width is large, and the shielding plate 1023 is not easy to swing and deform after being stressed.

As can be seen from the enlarged view of fig. 8, the rear end of the convex hull 10232 is not connected to the main body 10231, and the convex hull 10232 is actually a half convex hull. The convex hull 10232 is specifically shaped as follows: at first opening window 10237 on main part 10231, adopt the mode of punching press to form convex closure 10232 in the below of window 10237, the advantage of not being connected between convex closure 10232 and main part 10231 lies in convenient processing, moreover, the rear end of convex closure 10232 need not stretch when the punching press, thickness is great, and here mainly bears the impact of ground pin spigot 2031 when using, compare the form of full convex closure, can prevent the fracture damage of the department that connects convex closure 10232 rear end and main part 10231.

As shown in fig. 9 and 10, a contact spring 10234 is provided at the front end of the shielding plate 1023, and the contact spring 10234 and the convex hull 10232 are arranged in a staggered manner. The contact spring 10234 includes two second spring arms 102341, two second spring arms 102341 are oppositely arranged, and the second spring arms 102341 can be deformed to some extent. After the second elastic arm 102341 is disposed at the front end of the shielding plate 1023, as shown in fig. 14, when the shielding plate 1023 is in contact with the shielding mesh 107 for conducting communication, the second elastic arm 102341 is elastically deformed to ensure close contact, so that the contact reliability is improved, and the shielding effect is enhanced. In this embodiment, the second elastic arm 102341 is located at the front end of the shielding plate 1023, the stress applied to the second elastic arm 102341 is transmitted in the front-rear direction, and the material thickness of the shielding plate 1023 in the front-rear direction is much larger than the material thickness in the thickness direction, so that the force-bearing capacity of the shielding plate 1023 in the front-rear direction is larger than the force-bearing capacity in the thickness direction, and the shielding plate 1023 is not easily deformed in the front-rear direction under force. In practice, the second elastic arm 102341 with larger size and larger elastic force can be selected to make the contact between the shielding plate 1023 and the shielding mesh 107 more secure.

In this embodiment, in order to fix the shielding plate 1023 on the terminal element 1022 and the supporting frame 1021 and ensure that the female-end ground terminal 10222 in the terminal element 1022 is reliably contacted with the shielding plate 1023, the common ground of each female-end ground terminal 10222 in the same terminal module 102 is realized, and the common ground of each female-end ground terminal 10222 in the female-end connector 100 is realized through the shielding net 107, so as to improve the grounding shielding effect. As shown in fig. 2, 7 and 9, a rivet hole 10235 is formed through the female ground terminal 10222, and rivet holes are also formed through the holder 1021 and the terminal member 1022, and when assembling, the three are fixed together by a rivet 1024 passing through the holder 1021, the female ground terminal 10222 and the shield plate 1023. The rivet 1024 here is an insulator.

In order to ensure good contact between the shielding plate 1023 and the female terminal ground terminal 10222 and to prevent the female terminal signal terminal 10221 from being grounded by a certain space between the shielding plate 1023 and the female terminal signal terminal 10221, as shown in fig. 2, 7 and 9, a projection 10233 is provided on one side of the main body portion 10231 of the shielding plate 1023 facing the terminal part 1022, and the projection 10233 is arranged to project from the main body portion 10231. The protruding portion 10233 corresponds to the female ground terminal 10222 and extends along the direction of the female ground terminal 10222. As shown in fig. 2 and 3, a first elastic arm 102222 is provided on the female terminal ground terminal 10222, and a first elastic arm 102222 is arranged to protrude toward the convex portion 10233, and is brought into close contact with the convex portion 10233 by elastic deformation of the first elastic arm 102222, thereby achieving conductive communication.

In this embodiment, the rivet 1024 passes through the shielding plate 1023 and the female ground terminal 10222 in sequence to be riveted on the support frame 1021, so that the manufacturing process is simple.
