[0130] 6. To increase the soldering area of the first soldering portion 12 and the second soldering portion 23 of the corresponding second signal terminal 2S for better soldering of the electronic component 4, the third soldering surfaces 122 are provided on the left and right surfaces of the first soldering portion 12, and the fourth soldering surfaces 232 are provided on the left and right surfaces of the second soldering portion 23 of the corresponding second signal terminal 2S. Meanwhile, the third soldering surfaces 122 and the fourth soldering surfaces 232 are exposed on a surface of the plastic seat 3 in the vertical direction Z, such that when spray-coating the solder, in addition to the first soldering surface 121 being connected to the first mating portion 4a by the solder and the second soldering surface 231 being connected to the second mating portion 4b by the solder, the third soldering surfaces 122 may also be connected to the first mating portion 4a by the solder, and the fourth soldering surfaces 232 may also be connected to the second mating portion 4b by the solder. [0131] 7. The openings 401 are provided to one-to-one correspond to the intervals P, thus facilitating the precise soldering of the electronic components 4 onto the corresponding first soldering portions 12 and the second soldering portions 23 of the second signal terminals 2S through the openings 401. [0132] 8. The electrostatic discharge protection components 5 are used to dissipate the electrostatic energy, thereby preventing the electrostatic interference of the connector assembly. [0133] 9. The first plastic member 3A is embedded within the second plastic member 3B, and the first plastic member 3A does not pass beyond the second plastic member 3B in the front-rear direction X, thus facilitating miniaturization of the terminal module 200. [0134] 10. The protruding portions 36 of the first plastic member 3A are one-to-one correspondingly received in the receiving slots 38 of the second plastic member 3B. The first slot 381 stops a side of the first solder portion 12 of the first signal terminal 1S in the vertical direction Z, such that the first solder portion 12 of the first signal terminal 1S and the second solder portion 23 of the corresponding second signal terminal 2S are flush in the vertical direction Z, which is conducive to soldering of the electronic component 4. The second slot 382 exposes the tail end 13 of the first signal terminal 1S, thus facilitating the soldering of the first wire 71 in the first row of cables 7. [0135] 11. The second soldering portion 23 of each grounding terminal 2G extends to the corresponding separation wall 39 and is provided to be side-by-side with the tail portion 13 of the corresponding first signal terminal 1S along the left-right direction Y, thus facilitating the synchronous soldering of the first wire 71 and the second wire 72 of the first row of cables 7 to the first signal terminal 1S and the grounding terminal 2G. [0136] 12. The positioning slots 35 of the first plastic member 3A and the positioning posts 41 of the second plastic member 3B engage with each other in the vertical direction Z, and the assembling method is simple and reliable. [0137] 13. Compared to the case where the mounting slots 33 are provided at the portions where the first signal terminal 1S and its adjacent grounding terminal 2G are directly exposed, each mounting slot 33 is provided to run through the plastic seat 3. On one hand, it may limit and protect the electrostatic discharge protection component 5 in the front-rear direction X and the left-right direction Y, and on the other hand, it is conducive to the alignment soldering of the electrostatic component with the first signal terminal 1S and its adjacent grounding terminal 2G. [0138] 14. Each disposing slot 42 has a portion formed in the first plastic member 3A and another portion formed in the second plastic member 3B. By simply mating the first plastic member 3A with the second plastic member 3B, the disposing slots 42 are formed therebetween, such that the first solder portion 12 and the second solder portion 23 of the corresponding second signal terminal 2S may be aligned and exposed within the corresponding disposing slot 42. Compared to the first embodiment, it avoids the need to form the openings 401 in the second plastic member 3B. [0139] 15. The metal shielding sheet 6 covers the sides of the first plastic members 3A away from the terminal assembly 300 in the vertical direction Z, thus allowing the matching with the second plastic member 3B to stop the first plastic members 3A from detaching from the second plastic member 3B in the vertical direction Z.
