The first and

second power terminals

50b,70b of the present application have a terminal thickness greater than the thickness of the first and

second signal terminals

50c,70 c. In a specific implementation, the thickness of the first and

second ground terminals

50a and 70a may be the same as the thickness of the first and

second power terminals

50b and 70b or the thickness of the first and

second signal terminals

50c and 70c, and preferably, the thickness of the first and

second ground terminals

50a and 70a is the same as the thickness of the first and

second power terminals

And the formation of the recess 431 at the surface of the rear end connection part 43 of the middle metal plate 40 also makes it possible to increase the distance between the rear end connection part 43 and the first power terminal 50b, while the rear end of the second power terminal 70b has been bent downward at the rear end connection part 43 without affecting the second power terminal 70 b. The rest parts of the first and

second power terminals

second power terminals

50b,70 b.

If the first and

second ground terminals

50a,70a have the same thickness as the first and

second power terminals

50b,70b, the first and

second ground terminals

50a,70a are allowed to directly contact the metal middle plate 40 and are grounded, and the metal middle plate 40 contacts a grounding assembly (not shown) of a docking connector and becomes a part of a loop to reduce the temperature rise effect of the first and

second ground terminals

50a,70 a.

After injection molding, all of the first signal terminal front tape 56b, the front tape 48 of the metal middle plate 40, and the first power terminal front and

rear tapes

55b and 55a are cut off. The first insulator 60 of the first assembly has a plurality of through holes 61 formed therethrough.

Please refer to fig. 16 and 17, which illustrate a second embodiment of the present application, compared to the first embodiment, the difference between the second embodiment is: the strip-shaped hole 42 of the middle metal plate 40 is penetrated in the inserting direction, so that the middle metal plate 40 is divided into a completely independent middle body part 41b and two side body parts 41 a. At this time, the front ends of the first and

second power terminals

50b,70b do not need to be provided with a groove structure, and there is no risk that the first and

second power terminals

50b,70b are too close to the metal middle plate 40.

However, in this case, it is required to be changed that, in the forming process of the middle metal plate 40 in the stamping process, the middle main body portion 41b and the two side main body portions 41a are separately connected to the front tape 48 of the middle metal plate 40, so that the tape connection problem caused by the separation of the middle main body portion 41b and the two side main body portions 41a can be solved.

50b,70b position department surely goes out the strip hole 42 in terminal extending direction in order to avoid thickened first, second

power supply terminal

50b,70b with the problem that the metal middle plate caused the short circuit appears.

The terminal thickness of the first and second

terminal groups

50,70 is thickened to reduce the impedance, and further reduce the temperature rise effect of the terminal, and meanwhile, in order to ensure that the first and second

terminal groups

50,70 will not cause the short circuit with the metal middle plate 40 due to the thickness increase, the metal middle plate 40 between the first and

second signal terminals

50c,70c and the first and

second power terminals

50b,70b is cut off, so that the metal middle plate 40 only exists between the first and

second ground terminals

50a,70a, and the problem of short circuit between the terminals due to the thickness increase of the terminal is ensured not to occur.
