Each first electronic component 300 is welded to the connection part 23 of one of the first signal terminals S1 and to the corresponding first signal pad 205 on the circuit board 200, so that the first signal terminal S1 is electrically connected to the corresponding first signal pad 205 through the first electronic component 300. The first signal terminal S1 and the corresponding first electronic component 300 form a high-frequency signal transmitting end, while the third signal terminal S3 is a high-frequency signal receiving end.

[0079] As Figure 13 and Figures 15 to 17 shown, the first row of cables 500 includes a plurality of first signal core wires 501 and a plurality of first ground core wires 502. Two first signal core wires 501 are correspondingly welded to the rear side of the board body 201 corresponding to each convex part 203 to achieve electrical connection with a pair of first signal terminals S1. The first ground core wires 502 are welded together to the connection part 23 of the corresponding first ground terminal G1 and to the first ground pad 207 located behind the connection part 23 of the first ground terminal G1.

[0081] As Figure 12 shown, the connector assembly further includes an outer mold 700. The outer mold 700 is made of plastic material, and the rear side of the electrical connector 100, the circuit board 200, and the front ends of the first row of cables 500 and the second row of cables 600 are plastically coated through an injection molding process, so as to protect and stabilize the welding relationships between some of the conductive terminals 2 and the circuit board 200, between the first electronic components 300 and the first signal terminals S1 and the circuit board 200 respectively, between the circuit board 200 and the first row of cables 500, and between the second row of cables 600 and the third signal terminals S3.

[0082] The utility model has the following beneficial effects:

[0083] (1) By forming an interval P between the connection part 23 of the first signal terminal S1 and the first signal pad 205 of the circuit board 200 and arranging the first electronic components 300 at this interval P, such an arrangement can effectively shorten the setting width of the circuit board 200 in the front-rear direction Z, so as to achieve the purpose of saving space, which is beneficial to the miniaturization of the connector assembly. At the same time, it does not affect the placement of the first electronic components 300 and can also improve signal integrity.

[0084] (2) The circuit board 200 is mounted on the plastic base 3, and the whole does not exceed the range of the plastic base 3 in the front-back direction Z. That is, the circuit board 200 is added to the original space of the electrical connector 100 without adding extra setting space, which is beneficial to further miniaturize the connector assembly.

[0085] (3) The conducting portion 23 of the first grounding terminal G1 is welded to the first grounding pad 207 of the circuit board 200, or the first grounding core wire 502 is welded to the conducting portion 23 of the first grounding terminal G1 and the first grounding pad 207 of the circuit board 200 together. Both setting methods can stabilize the connection between the electrical connector 100 and the circuit board 200 and prevent the swing of the first row of cables 500 from affecting the stability of the installation of the first electronic component 300.

[0086] (4) A plurality of relief grooves 202 are provided at the front end of the circuit board 200. The relief grooves 202 can provide relief for the first grounding terminal G1 in the up-down direction X. On the one hand, it can make the main body portion 21 of the first grounding terminal G1 not need to be bent to avoid the circuit board 200, simplifying the forming process of the first grounding terminal G1. On the other hand, it can make the plastic base 3 retain its original size in the up-down direction X and prevent the size of the plastic base 3 from increasing in the up-down direction X due to the bending of the main body portion 21 of the first grounding terminal G1 to avoid the circuit board 200.

[0087] (5) The setting of the first electronic component 300 and the second electronic component 400 can play the role of signal filtering and DC blocking, and is also beneficial to improving signal integrity.

[0088] (6) The conducting portion 23 of the second signal terminal S2 and the conducting setting of the second grounding terminal G2 are arranged on the front side of the first grounding terminal G1. In this way, the lengths of the second signal terminal S2 and the second grounding terminal G2 are shortened, and the space occupied by the shortened length is used to provide relief for the protruding plate 204. A protruding plate 204 is provided at the front end of the circuit board 200 corresponding to the second grounding terminal G2 of the second signal terminal S2. In this way, when the second signal terminal S2 and the second grounding terminal G2 are welded to the protruding plate 204, there is still space between the protruding plate 204 and the plate body 201 to weld the second electronic component 400.

[0089] (7) Providing a stop portion 31 on the plastic base 3 is beneficial to stopping the circuit board 200, so that the interval P formed by the first signal pad 205 on the circuit board 200 and the first signal terminal S1 is within the specified range.

[0090] (8) The plastic base 3 is provided with a plurality of receiving grooves 33 arranged in the left-right direction Y. The circuit board 200 is provided with a plurality of protrusions 203 corresponding to the plurality of receiving grooves 33. The protrusions 203 of the circuit board 200 can be respectively embedded into the plurality of receiving grooves 33 one by one, so as to facilitate the precise alignment in the front-back direction Z between the first signal pads 205 on the protrusions 203 and the connection parts 23 of the first signal terminals S1.

[0091] (9) The outer mold 700 plastically coats the rear side of the electrical connector 100, the circuit board 200, and the front ends of the first row of cables 500 and the second row of cables 600, so as to protect and stabilize the soldering relationships between the partial conductive terminals 2 and the circuit board 200, between the first electronic component 300 and the first signal terminal S1 and the circuit board 200 respectively, between the circuit board 200 and the first row of cables 500, and between the second row of cables 600 and the third signal terminal S3.
