During assembly, the first limit block 304, the second limit block 404, the third limit block 704, and the fourth limit block 804 are respectively inserted from top to bottom and limited in the limit groove 220. Of course, in a preferred embodiment, the first support member 5 and the second support member 6 can also be provided with a structure similar to the first limit block 304 at both ends along the left and right directions, and correspondingly limited in the limit groove 220.

[0066] When manufacturing the high-speed electrical connector of the present application, the first step is to install the first terminal assembly 3 from top to bottom into the lower plastic shell 2 to form a first module; the second step is to install the first support member 5 from top to bottom into the lower plastic shell 2 (in the first module) to form a second module; the third step is to install the second terminal assembly 4 from top to bottom into the lower plastic shell 2 (in the second module) to form a third module; the fourth step is to install the second support member 6 from top to bottom into the lower plastic shell 2 (in the third module) to form a fourth module; the Step 5: Install the third terminal assembly 7 from top to bottom into the lower plastic shell 2 (inside the fourth module) to form the fifth module; Step 6: Install the fourth terminal assembly 8 from top to bottom into the lower plastic shell 2 (inside the fifth module) to form the sixth module; Step 7: Cover the upper plastic shell 1 on the lower plastic shell 2 (on the sixth module); Step 8: Finally, install and buckle the metal shell 92 to the outer periphery of the upper plastic shell 1 and the lower plastic shell 2, and at the same time, lock the front end position of the upper plastic shell 1 and the lower plastic shell 2 with the locking piece 91.

[0067] Please refer to Figures 16 to 18 As shown, the lower surface of the lower plastic shell 2 of the present application is also protruded to form an installation positioning column 24, and the installation positioning column 24 is used to be inserted into the positioning hole on the docking circuit board during installation. The installation positioning column 24 is sleeved with a welding fixing sheet 93, and the welding fixing sheet 93 is formed with a main body (unnumbered) surrounding the outer periphery of the installation positioning column 24 and attached to the lower surface of the base 21, and a fixing foot (unnumbered) extending upward from the edge of the main body and inserted and fixed into the base 21. The main body of the welding fixing sheet 93 is used to be welded and fixed to the gold finger on the docking circuit board.

[0068] It should be noted that, in the embodiment of the present application, the terminal assembly is provided with four groups, namely the first terminal assembly 3, the second terminal assembly 4, the third terminal assembly 7, and the fourth terminal assembly 8. Of course, in other embodiments, the terminal assembly may be provided with only two groups, for example, only the first terminal assembly 3 and the second terminal assembly 4. At this time, a row of first terminal contact portions 3021 of the first terminal assembly 3 and a row of second terminal contact portions 4011 of the second terminal assembly 4 are configured to be provided correspondingly along the up-down direction.

[0069] In the innovative solution of the present application, the upper plastic shell 1 and the lower plastic shell 2 are designed to be two-piece, and the first terminal assembly 3, the second terminal assembly 4, the third terminal assembly 7, the fourth terminal assembly 8, the first support member 5, and the second support member 6 are designed to be assembled from top to bottom into the lower plastic shell 2, so that the base 21 of the lower plastic shell 2 can be configured to form a structure of the first beam portion 212, the second beam portion 213 and the third beam portion 213, so that the overall structure of the high-speed electrical connector is more solid, especially the base portion of the lower plastic shell 2. In addition, the position setting of the first docking pin 311, the second docking pin 411, the third docking pin 711, and the fourth docking pin 811 can be made more accurate. The open structure of the lower plastic shell 2 can also make the installation direction of the first terminal assembly 3, the second terminal assembly 4, the third terminal assembly 7, the fourth terminal assembly 8, the first support member 5, and the second support member 6 unified (including the installation direction of the locking member 91 and the metal shell 92), making the installation easier.

[0070] In a modified embodiment of the present application, the rear end of the lower plastic shell 2 or the upper plastic shell 1 can also be integrally formed with a rear end plate (not shown), and the rear end plate can isolate the rear position of the fourth terminal assembly 8 from the outside world. Of course, in other modified embodiments, the rear end of the metal shell 92 can also be integrally formed with a rear wall (not shown).

[0071] In a modified embodiment of the present application, the two side panels 12 of the upper plastic shell 1 may not be provided, and the two side walls of the lower plastic shell 2 may be extended higher upward, and the upper plastic shell 1 may only be provided with a plate-shaped cover-like structure.

[0072] In addition, it should be noted that in the present application, the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application. For example, the lower plastic shell 2 is not specifically a component that fits with the docking circuit board, and the upper plastic shell 1 can also be designed to fit and assemble with the docking circuit board. In this case, it is only necessary to design the structure of the first terminal assembly 3, the second terminal assembly 4, the third terminal assembly 7, the fourth terminal assembly 8, the first support member 5, and the second support member 6 to be assembled into the upper plastic shell 1 after being turned upside down, and the lower plastic shell 2 is designed to be similar to a cover structure.

[0073] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features.

[0074] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
