[0065] like Figure 1-37As shown, it is a cable assembly 500 in accordance with an embodiment of the present invention, the cable assembly 500 includes an outer shell 502 and two groups of cable modules 600 covered by the shell 502, and the two groups of cable modules 600 are arranged in two rows along the transverse direction X. Each group of cable modules 600 includes a plurality of units 610 arranged side by side along the row direction (i.e., the transverse direction). Each unit 610 includes a front docking member located at the front, and the front docking member includes a signal terminal portion 620 and a grounding terminal portion 630. The signal terminal portion 620 includes an insulator 622 or an inner part, and the insulator 622 or the inner part is integrally formed with a pair of signal terminals 624 by injection molding. The signal terminal 624 includes a deflectable contact portion 626 exposed at the bottom of the insulator 622 and a connecting portion 628 exposed at the upper end of the insulator 622. The grounding terminal portion 630 includes a U-shaped grounding terminal 634 and an insulating housing unit 632 or an outer part integrally formed with the U-shaped grounding terminal 634. The grounding terminal 634 includes a pair of deflectable contact portions 636 exposed at the bottom of the housing unit 632 and a connecting portion 638 exposed at the upper end of the housing unit 632. The housing unit 632 or outer member includes a first side wall 6321, a second side wall 6322 spaced apart from and parallel to the first side wall 6321, a connecting wall 6323 connecting the first side wall 6321 and the second side wall 6322, and a cavity or receiving space 637 formed by the first side wall 6321, the second side wall 6322 and the connecting wall 6323. One of the grounding terminals 634 is molded and fixed on the first side wall 6321, and the other grounding terminal 634 is molded and fixed on the second side wall 6322. It is worth noting that the insulator 622 is inserted forward along the front-to-back direction Y and is received in the cavity or receiving space 637 of the housing unit 632. Each unit 610 includes a cable 700 at the rear, the cable 700 includes a differential core pair 702 and a ground wire 704, the differential core pair 702 is welded to the connection portion 628 of the signal terminal 624, and the ground wire 704 is welded to the connection portion 638 of the ground terminal 634. A pair of ground terminals 634 includes a bridge 6340 connecting the pair of ground terminals 634. The bridge 6340 is molded in the connecting wall 6323, and the ground wire 704 is mechanically and electrically connected to the bridge 6340. The insulator 622 includes a pair of slide grooves 623, and the housing unit 632 includes a slide rail 631, and the slide groove 623 accommodates the corresponding slide rail 631 on the housing unit 632. In this embodiment, the housing unit 632 is molded as a whole. It can be understood that the housing unit 632 of the ground terminal portion 630 in the same group of cable modules 600 is formed as a whole, which not only has good strength, but also can maintain uniformity. In addition, the U-shaped structure of the ground terminal 634 not only effectively shields the corresponding pair of differential signal terminals 624 , but also enhances the overall structure of the integrated housing 635 .The cables 700 of all the units 610 are connected together as a round cable 710 to extend out of the rear end of the housing 502. Fig.16 As shown, the cable 700 omits the ground wire, and the ground terminal 634 omits the bridge piece.

[0066] The ground terminal portion 630 is formed by arranging a plurality of ground terminal carriers 633, which are closely arranged side by side with each other in the lateral direction, and each ground terminal carrier 633 integrally includes three ground terminals 634 in the front-rear direction. The housing unit 632 is integrally molded on the ground terminal carrier 633 by an injection molding process, so that the housing units 632 in the same column in the lateral direction are combined with each other to form an integral housing 635. The three integral housings 635 made of the unified housing unit 632 are separated from each other by cutting off parts A, B, C and D of the ground terminal carrier 633. The integral housing 635 includes a pair of guide rails 640 on opposite outer sides, and the guide rails 640 are accommodated in corresponding guide grooves (not shown) in the inner surface of the housing 502.

[0067] In this embodiment, the cable assembly 500 is inserted into the inner space of the fixture 900', and the fixture 900' is mounted on the printed circuit board 950'. Two rows of conductive sheets 952' are included on the printed circuit board 950' below the inner space. The fixture 900' includes an inclined upper wall and two side walls connected to the upper wall, and an entrance is formed between the side wall and the upper wall to allow the cable assembly 500 to enter the fixture 900' and cooperate with the conductive sheets 952'. The housing 502 of the cable assembly 500 is also provided with a pair of guide protrusions 504 on two opposite outer surfaces, and the guide protrusions 504 are accommodated in the corresponding guide grooves 902' on the inner surface of the fixture 900', and the guide grooves 902' extend obliquely. It can be understood that because the housing 502 is assembled into the fixture 900' in an inclined direction, when the housing 502 reaches the final position, the contact portions 626 and 636 are deflected in the vertical direction Z to effectively mechanically and electrically connect to the corresponding conductive sheets 952'. It is understandable that the housing 502 and the holder 900 ′ may form some retaining mechanisms or guiding mechanisms to reliably retain the housing 502 in a proper position within the holder 900 ′.

[0068] The main feature of the present invention is that the two rows of cable modules 600 provide two corresponding rows of deflectable contact portions 626, 636, which are deflected to simultaneously connect the corresponding conductive strips 952'. The bottom side of the unit 610 of the two sets of cable modules 600 defines a mating surface of the housing 502, which is inclined to the main plane of the housing 502 and is located at the front end of the cable assembly 500. In other words, the inclined arrangement of multiple rows of cable modules and keeping the corresponding contact portions of all cable modules in the same plane is the main feature of the present invention.

[0069] like Figure 30-37 As shown, it is another embodiment of the ground terminal portion 660. Each ground terminal portion 660 includes a pair of ground terminals 664, which are molded in two opposite side walls of the insulating housing unit 662. The ground terminal 664 includes a deflectable contact portion 666 on the bottom side of the insulating housing unit 662, and the contact portion 666 is used to connect to the corresponding conductive sheet on the printed circuit board. It can be understood that in this embodiment, the terminal carrier 663 is located in a vertical plane, so that no corresponding connection portion for welding to the corresponding ground wire is formed, which is equivalent to the bridge member in the first embodiment. However, if necessary, the ground terminal can be provided with a horizontal connection portion through the terminal carrier 663 so as to be welded to the corresponding ground wire. Similar to the first embodiment, the insulating housing units 662 located in the same row in the lateral direction are combined together to form an integrated housing 665.
