In order for the examiner to fully understand the socket connector of the present invention, the following is explained in the following figures.

As shown in FIG. 1 to FIG. 4, the socket connector of the present invention comprises at least a socket body 1 and a mounting space 10 for the terminal block 2. The installation space 10 is disposed and positioned for the terminal block 2, and the terminal block 2 is self-connected. The socket body 1 is provided with a slot 11 , and the inner wall surface of the slot 11 is provided with a plurality of positioning slots 12 when the socket connector is to be connected to the plug. The devices are inserted into each other, that is, the positioning slots 12 are used to form a combination of the socket connector and the external plug connector in a certain direction to avoid generating an erroneous signal. Other components of the socket connector are known in the art and will not be described herein.

As shown in FIG. 3 to FIG. 3, the socket connector of the present invention is provided with a terminal block 2, and the terminal block 2 is provided with an installation space 20 of an insulating component. The foregoing installation space 20 can be disposed and positioned for the insulation component 21; One or more insulation units 21a, 21b (the invention is explained by two insulation units The insulating unit 21a, 21b of the insulating component 21 is provided with one or more male terminal holes 210, and each of the male terminal holes 210 may be provided with a male terminal 211, which is provided by each insulating unit 21a, 21b. The public terminal 210 is connected to the corresponding signal line to form a signal transmission system 21c, 21d. The present invention comprises two sets of signal transmission systems 21c, 21d, respectively, by insulating units 21a and 21b, and then each of the foregoing insulating components 21. The shielding unit 3 is disposed between the insulating units 21a and 21b to isolate the front end of the shielding assembly 3 from being flush with the front end of the insulating unit 21, and the front end of the male terminal 210 is longer than the front end of the shielding unit 3 (as shown in the figure). 4 and 6), and are exposed in the front range of the installation space 20. The shielding component 3 is preferably made of a metal material (such as copper metal), but can be made of a non-metal material (such as carbon fiber) having a crosstalk prevention mechanism for each group of signal transmission systems. The shielding component 3 has a Or two or more components (the invention is explained by a shielding component), the shielding component 3 has separate components from the terminal block 2, and the shielding component 3 is maintained in contact with the terminal block 2 (as shown in FIG. 3). The shield assembly 3 produces an effect of grounding. However, if the technology can be overcome, it can also be integrally formed with the terminal block 2, and it is also impossible. The shielding component 3 is composed of one or two or more, mainly depending on the number of groups of the signal transmission systems 21c and 21d. For example, the socket connector has more than two groups (excluding two groups) of the signal transmission system 21c, 21d, the shielding component needs to have at least two sets to fully isolate the groups of signal transmission systems 21c, 21d. Therefore, the arrangement of the shielding component 3 is determined according to the setting manner of each signal transmission system 21c, 21d.
