Referring to fig. 10 to 13, in a second embodiment of the high speed connector 100' of the present invention, the fixing portion 5 is formed by extending laterally from the lateral side 33. The fixing portion 5 includes a connecting portion 51 formed by bending and extending downward from the outer side of the side member 33, and a tray 52 formed by bending and extending laterally from the connecting portion 51.

The fixing hole 53 is disposed corresponding to the protruding pillar 161, and the fixing hole 53 is fixed to the protruding pillar 161 by interference fit.

Referring to fig. 1 to 9, in the manufacture of the high-speed connector 100, the first embodiment of the present invention provides the following steps in combination with the description in the above specification:

the first step, providing an insulating material, and obtaining an insulating body 1 with the base 10 by an injection molding mode;

a second step of providing a flat-plate-shaped metal material, and obtaining the metal reinforcing part 3 in a punch forming mode;

and a third step of mounting the metal reinforcing member 3 on the upper surface 11 of the base 10 from top to bottom. The main body 31 of the metal reinforcing member 3 is disposed on the second surface 16, and the first surface 141 extends upward beyond the top surface of the main body 31. In this process, the fixing portion 4 is inserted downward into the fixing groove 15, the bottom ends of the pair of elastic arms 42 move downward along the smooth inclined surface of the bell mouth 151, and along with the gradual narrowing of the bell mouth 151, the pair of elastic arms 42 elastically deform in the front-rear direction in opposite directions so as to finally make the hook portion 42 of the elastic arm 42 pass downward through the bottom end of the bell mouth 151 and enter the observation hole 152, at this time, the pair of elastic arms 42 is released from the elastic deformation state in the front-rear direction so as to make the hook portion 42 upwardly clamp the step portion 153, so as to fix the metal reinforcement 3 and the base 10. At this time, the protruding arm 37 is held between two adjacent protruding island portions 14 in the front-rear direction and is correspondingly suspended in the concave portion 17, and the concave portion 17 can provide more holding space for the protruding arm 37 in the up-down direction, which is more beneficial to the mounting accuracy and stability between the middle portion of the main body portion 31 of the metal reinforcing member 3 and the base 10. At this time, each spring piece 36 of the metal reinforcing member 3 is positioned above the corresponding second mounting hole 13G.

And a fourth step of providing a flat-plate-shaped metal material, and obtaining the signal terminal S and the grounding terminal G in a punch forming mode.

And a fifth step of inserting the signal terminals S into the first mounting holes 13S from top to bottom and inserting the ground terminals G into the second mounting holes 13G from bottom to top. At this time, the elastic sheet 36 elastically abuts against the surface of the ground terminal G in the front-back direction, so as to achieve the purpose of grounding all the ground terminals G of the high-speed connector 100 together.

In the above manufacturing process, the timing sequence of the manufacturing of the base 10, the metal reinforcement 3, the signal terminal S and the ground terminal G defined in the first step, the second step and the fourth step is not exclusive, and the scope of the description of the present specification should not be limited thereto.

Referring to fig. 10 to 13, in the manufacture of the high-speed connector 100', the second embodiment of the present invention, which is described in the above description, is mainly different from the manufacture of the first embodiment in that the fixing portion 5 and the fixing groove 18 are fixed in the third step: in the second embodiment, the tray 52 of the metal reinforcement 3 corresponds to and is fitted into the fixing groove 18. In the process, the fixing hole 53 allows the convex column 161 to pass through upwards for fixing. Because the convex columns 161 are uniformly provided with a plurality of convex ribs 162 on the peripheral sides, the inner sides of the fixing holes 53 and the convex columns 161 can be fixed more firmly. At this time, in order to prevent the fixing hole 53 from being separated from the boss 161, the top end portion of the boss 161, which is exposed through the fixing hole 53, may be pressed downward to form a cover 163 having an outer diameter larger than the inner diameter of the fixing hole 53, so as to achieve a better fixing effect. Of course, the convex rib 162 may be narrowed gradually from top to bottom, the size of the upper end of the convex rib 162 is larger than the inner diameter of the fixing hole 53, and when the convex pillar 161 pushes upward through the inner side of the fixing hole 53, the fixing portion 5 may be prevented from being separated from the convex pillar 161. The larger upper end portion of the cover 163 or the rib 162 is an abutting portion that abuts the tray 52 downward, and when viewed in the up-down direction, the larger upper end portion of the cover 163 or the rib 162 overlaps the tray 52. The cover 163 and the rib 162 generally have high similarity, and the embodiment is merely an example and is not only for explanation.

In another embodiment of the present invention, in the fifth step, the elastic sheet 36 corresponds to the ground terminal G but is not in contact with the ground terminal G, but a sixth embodiment is added to deform the elastic sheet 36, so that the elastic sheet 36 is in contact with the ground terminal G. The deformation of the elastic sheet is known in the art, and is not described herein.

Since the elastic sheet 36 is formed in an upward bending manner, in the process of inserting the ground terminal G, the contact portion of the ground terminal G slides on a smooth surface, thereby preventing the ground terminal G from being scratched by the elastic sheet 36.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only express preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
