Description of the Invention: [Technical Field] The present invention relates to an electrical connector, and more particularly to a connector for transmitting a south frequency signal. [Prior Art] Connection benefits are widely used to connect skirts for communication or data transmission. In order to cater for the transmission of large amounts of data, the speed of data transmission continues to increase. As the data transfer speed increases, the connector 2 with a lower transfer speed must be redesigned to ensure signal integrity. Figure 1 shows a conventional stacked connector i, and Figure 2 shows a plurality of terminals 2 and 9 spaced apart in a stacked connector. The laminated connector 1 includes a casing u including an upper socket 111 and a lower socket 112, and the upper socket and the lower socket 112 are for individually holding the contact portions 21 and 91 of the terminals 2 and 9 arranged side by side. Each of the upper terminal 2 or the lower terminal 9 further includes a hook portion 22 or 92 connecting the contact portion 91 and an extension portion 23 or 93 ^ extension portion 23 or a % self-piercing hook portion η connecting the sling portion 2 or 92 Or 92 extends and is vertically folded f' and then extends straight to form one end of a through hole for soldering to a printed circuit board. A plurality of upper terminals 2 are partially housed in the upper socket (1) and include two ground terminals 27 and 28 and two differential terminal pairs and 25. Between the two differential terminal pairs 24 and 25, a ground pin 26 similar to the differential terminal pair and the upper terminal 2 of 25 is provided. The two grounding terminals are respectively connected to opposite sides of the pair of differential terminals 24 and 25. Similarly, the plurality of lower terminals 9 partially accommodated in the lower socket 112 include two grounding terminals 97 201136039 and 98. Two differential terminal pairs 94 and 95 and a grounding pin 96 disposed between the two differential terminal pairs 94 and 95. The two differential terminal pairs 24 and 25 accommodated in the upper terminal 2 of the upper socket U1 have longer than partial capacitance. The extension 23 of the extension 93 of the lower terminal 9 of the lower socket 112. Accordingly, when the two differential terminal pairs 24 and 25 of the upper terminal 2 are applied to high speed data transmission (for example, 3 Gbps:), the longer extension 23 The integrity of the signal transmission cannot be ensured. In addition, the grounding pin 26 or 29 containing a structure similar to the terminal 2 or 9 does not provide sufficient shielding effect, which will cause signal integrity to be defective. Furthermore, the extension of the terminal 2 or 9 The portion 23 or 93 is bent vertically, and the vertically bent upper terminal 2 may affect the transmission of the signal. Furthermore, since the plurality of terminals 2 and 9 are arranged neatly, the electric field generated from the differential terminal pairs 24 and 25 is not the most Jiahua, so the signal Output will have an adverse effect summary 'previously mentioned defects, SUMMARY OF THE INVENTION One object of the present invention to provide a new system comprising a dielectric housing, at least one of - a mating connector.
