The computer uses a variety of devices to transmit f at high speeds and high t-degrees. For example, U.S. Patent No. 6,336,827, "Balanced Signal Line and Electrical Connector Unit" is an example of such a device. Η 1 shown in FIG. 2, in the case of the balanced signal line and electrical connector unit 1, the metal line 12 of the signal line 12, the bare line 121 is connected to the signal contact lU and the ground contact 112 of an electrical connector 11. And the electrical connector U is electrically connected to the signal line 12 via the printed circuit board 13. - The metal casing 14 is mounted to cover the printed circuit board 13 and the above components are combined with the printed circuit board 13. In addition, the signal line and the electrical connector unit further include an insulative housing 插5 that is inserted into the front end of the metal casing 14. Since the signal line 12 is connected to the signal contact board and the ground contact 112 by a transfer of the printed circuit board 13, the signal line 12 is indirectly connected to the signal contact m and the ground contact 112, thereby reducing data transmission. Rate, which is a disadvantage of the above device. In addition, since the data must be transmitted via an external component (such as printed circuit board 13), the data increases the likelihood of distortion, 1263381, thus reducing the overall reliability of data transmission. On the other hand, the bare wires 121 of the metal wires 120 are disposed between the brushed road boards 13 at intervals, and are not provided with electromagnetic shielding. Therefore, the bare wires 121 are caused to be crosstalk due to the interference of the magnetic wave (7) "仏1匕) and the noise problem, the result will reduce the quality of the data transmission.

On the first part 311. In this embodiment, each of the signal lines 211 may be disposed on each of the insulating layers 1263381 323 between each pair of the first grounding spacers 324. The metal shield 34 can include two housing portions 340 that respectively cover the top and bottom ends of the first portion 311. The housing portion 34 of each of the metal shields 34 has a plurality of through holes 342 (Fig. 5), and the through holes 342 of each of the housing portions 34 of the metal shield 34 are respectively passed through the grounding wire 212 (Fig. 6). The grounding wire 212 can be soldered to the metal shield 34 when disposed within the perforation (4), but the weld is not required to be displayed. On the other hand, the ground line 212 is electrically connected to the metal shield 34. The ground contact 325 of the terminal block 31 can be used to interface with a grounded contact (not shown) of a mating electrical connector and electrically coupled to a printed circuit board (not shown). Therefore, the ground contact 325 can be grounded via a ground pad formed on the printed circuit board. Finally, since the second grounding spacers 341 are embedded in the longitudinal grooves 326, respectively, and since the first grounding spacers 324 are integrally formed with the grounding contacts 325, the grounding wires 212 are grounded via the grounding contacts 325. Alternatively, the signal transmission line 2 can be grounded, for example, by a conventional metal-clad structure (not shown) disposed outside the insulating sheath 22. Referring again to Figure 5, the sum of the electrical connections 2 includes a metal casing 4 covering the electrical connection Jie 3 and the carrier 24, as part of the signal transmission line 2 is connected and covered with the electrical connector 3 and Inside the carrier 24. The metal casing* includes a pair of main bodies 42' and the electrical connector 3 and the carrier 24 are interposed between the two main housings 42. The two locking bolts 41 are disposed between the main casing 42 along the opposite sides of the main casing 42 and substantially in the axial direction of the signal transmission line 2. Locking inspection 41. The metal casing 4 is fixed to an electronic device (not shown) in a generally used manner. The electrical connector of the above-mentioned electrical connector 200, because the conductive terminal 33 is directly connected to the signal line 211, 211 of the signal transmission line 2, and the electrical connector contact disclosed in the US Patent No. β, 336, 827, Comparing 112 with the signal transmission line bare line 121 via the printed circuit board 13 for indirect connection, a faster data transmission rate can be achieved. In addition, since the first and second grounding spacers 324, 341 completely block the signal lines 211, 211, electromagnetic wave interference does not occur between the signal lines 211, 21A. Further, the metal seat 32 simplifies the combination between the first and second grounding spacers 324, 341 and the conductive terminals 33. In addition, the 'use of the metal casing 4' can be used to protect the signal between the components and avoid external electromagnetic interference. The main feature of the invention is the use of the terminal module 31. The metal seat 32 of the terminal module 31 is formed by the unique structure of the terminal groove 32a, and can provide an effective electromagnetic wave barrier between the conductive terminals 33. Since the insulating layer 323 is covered in the terminal groove 32a, a short circuit will not occur between the conductive terminals 33. The terminal module 31 is manufactured by covering the metal seat 32 with an insulative housing 32, and the terminal block 32a is formed in advance on the metal seat 32. The insulating layer 323 is formed on the insulating body 320 at the time of injection molding. Further, it is possible to replace the insulating layer 323 with the isolating coating layer 323a (Fig. 15). When the terminal module has been described with respect to the present invention for signal transmission line connection 200, the application of the present invention is not limited thereto. The invention is also applicable to other types of connectors, and the connector includes a plurality of conductive terminals for transmitting signals. An example of such a connector is shown in Figures 16-23. As shown in Figs. 16 to 19, the terminal molds ^263381, and 500 of a plug connector are used to be connected to a circuit board. The plug connector includes a metal seat 5 () 1 having a plurality of vertical slots 502, each of which is covered with an insulating layer 503. The plurality of conductive terminals 5〇4 are respectively inserted in the insulating layer 5〇3. As shown in FIG. 2 to FIG. 23, the terminal module 600 of a socket connector is used for connection with a circuit board. The terminal module 6A includes a metal seat 601 having a plurality of terminal slots 602, each of which is covered with an insulating layer 6〇3. The plurality of conductive terminals 6〇4 are respectively inserted in the insulating layer 6〇3. The metal seats 501, 601 can be manufactured by using a suitable metal material for forming. For example, the metal seats 5〇1, 6〇1 can be made by using a casting process such as an aluminum-magnesium alloy or an aluminum alloy. Metal seats 5〇1, 6〇1 can also be used in powder metallurgy technology, and metal powder such as copper is used as the material. The insulating layers 503 and 6〇3 may be separately formed into one piece and inserted into the terminal grooves 502 and 6〇2, respectively. The insulating layers 5〇3, 6〇3 can be integrally formed by injection molding. In this example, the insulating layers 503, 603 will be joined to the insulative body molded over the metal seats 501, 601. The plug and socket connectors 500, 600 are a single unit like the metal seats 5〇1, 6〇1, and each of the terminal slots 502, 6〇2 is limited to a metal wall wrapped around the corresponding conductive terminals 504, 604. And no discontinuities or gaps are formed in the conductive terminals 5〇4, 6〇4. As a result, effective electromagnetic wave shielding occurs between the conductive terminals 5〇4, 604. In addition, a single individual metal seat 501 601 can be conveniently fabricated without complicated assembly steps.
