[0021] like Figure 1-15 As shown, the embodiment of the present invention includes two rows of cable connector assemblies 100, and the two rows of cable connector assemblies 100 are collectively accommodated in a holder 900 mounted on a circuit board 800 in an inclined manner, and the circuit board 800 is provided with a conductive sheet 802. The holder 900 includes an upper inclined wall 901, a lower inclined wall 903 spaced apart from the upper inclined wall 901 and parallel to the upper inclined wall 901, and an inclined channel or entrance 902 formed between the upper inclined wall 901 and the lower inclined wall 903 in an inclined direction, so that the cable connector assembly 100 enters the holder 900 and cooperates with the conductive sheet 802.

[0022] Each cable connector assembly 100 includes a front docking member 110 having a wedge-shaped cross section, a pair of signal terminals 120 held on the front docking member 110, a pair of grounding terminals 130 located on both sides of the pair of signal terminals 120 and mechanically and electrically connected to the internal grounding shell 300, and a rear cable 200 connected to the rear of the front docking member 110 and provided with a pair of signal lines 210. Each of the signal terminals 120 is provided with a middle holding portion 122 partially surrounding the front docking member 110, a front docking portion 124 spaced apart from the front docking member 110 in a deflectable manner, and a rear connecting portion 126 mechanically and electrically connected to an inner conductor (not shown) of the signal line 210 and spaced apart from the front docking member 110 in a deflectable manner. The front docking member 110 is provided with a pair of grooves 112 for accommodating the front ends of the front docking portions 124 of the pair of signal terminals 120 to prevent the deflectable front docking portions 124 from being mechanically stuck. The pair of grounding terminals 130 are located on both sides of the pair of signal terminals 120 in the lateral direction. The front docking portion 124 is used to directly dock with the conductive sheet 802 of a circuit board disposed in a plane, and the rear cable 200 extends in a direction inclined to the plane.

[0023] Each cable connector assembly 100 further includes a shielding shell provided with a partition wall 410, so that the front docking piece 110 of one cable connector assembly 100 in the front row is shielded from the front docking piece 110 of another cable connector assembly 100 in the rear row in the front-to-back direction. The shielding shell includes an inner shielding shell 300 covering the front end of the rear cable 200. The rear cable 200 further includes a grounding wire 220 electrically connected to the inner shielding shell 300. In this embodiment, the inner shielding shell 300 is a tubular metal shell mechanically connected to the grounding wire 220 of the rear cable 200, which includes a platform 302, and the front docking piece 110 is located on the platform 302. The grounding terminal 130 is mechanically and electrically connected to the inner shielding shell 300, and is located on both sides of the pair of signal terminals 120 in the lateral direction.

[0024] The shielding shell includes an outer shielding shell 400 covering and electrically connected to the inner shielding shell 300. The outer shielding shell 400 is electrically connected to the pair of grounding terminals 130. In the present embodiment, the outer shielding shell 400 is a tubular metal surround shell. The partition wall 410 is integrally formed on the outer shielding shell and is separated from the bottom wall 412 of the surround shell 400 to form an opening 414 in front of the partition wall 410. The front docking member 110 extends downward through the opening 414 to allow the front docking portion 124 of the signal terminal 120 to be located on the corresponding conductive sheet 802 for connection.

[0025] It is understood that the retainer 900 forms an inclined passage or entrance 902 to adjust the corresponding cable connector assembly 100 in an appropriate position. The support plate 904 is detachably attached to the retainer 900 to form an inclined passage or entrance 902 after the cable connector assembly 100 is obliquely installed in the retainer 900. The lower inclined wall 903 is formed on the upper surface of the support plate 904. The side of the outer shield shell 400 can form corresponding interengagement structures, such as tenons and mortises, so as to allow adjacent cable connector assemblies 100 to be arranged together in a row.

[0026] In this embodiment, only a 2x2 cable connector assembly 100 is shown. This design can also realize an N×M matrix arrangement of the cable connector assembly 100. In this embodiment, the inner shielding shell 300 and the outer shielding shell 400 separated from each other jointly form a shielding shell structure. Alternatively, it is also feasible that the inner shielding shell 300 and the outer shielding shell 400 are a unified structure. In this embodiment, a pair of grounding terminals 220 are independently provided with the inner shielding shell 300. The pair of grounding terminals 220 can also be integrally formed on the inner shielding shell 300.

[0027] In this embodiment, the partition wall 410 is located between adjacent cable connector assemblies 100 in the front-to-back direction. The partition wall 410 may also be located between adjacent cable connector assemblies 100 in a transverse direction perpendicular to the front-to-back direction and the vertical direction. It is worth noting that in this embodiment, the rear side of the front docking member 110 is recessed to accommodate the corresponding partition wall 410.
