[0085] Please refer to Figures 1 to 11As shown, in the first embodiment of the present invention, a terminal module 100 is disclosed, which includes a plurality of first conductive terminals 21, an insulating body 1 and a first shielding sheet 31. More specifically, in the first embodiment of the present invention, the terminal module 100 also includes a plurality of second conductive terminals 22 and a second shielding sheet 32. In addition, in order to facilitate assembly, the terminal module 100 includes a first terminal assembly 10 and a second terminal assembly 20, wherein the first terminal assembly 10 includes a first insulating block 41, the first insulating block 41 is fixed with the first conductive terminal 21 and the first shielding sheet 31 to form a whole; similarly, the second terminal assembly 20 includes a second insulating block 42, the second insulating block 42 is fixed with the second conductive terminal 22 and the second shielding sheet 32 to form a whole. The terminal module 100 also includes a third insulating block 43 that is secondary molded on the first terminal assembly 10 and the second terminal assembly 20. It can be understood by those skilled in the art that after the third insulating block 43 is molded on the first insulating block 41 and the second insulating block 42, the three are combined into one body and are collectively referred to as the insulating body 1.
[0086] In the first embodiment of the present invention shown in the figure, the first insulating block 41 is injection molded on the first conductive terminal 21. Each first conductive terminal 21 includes a first conductive sheet 211, a second conductive sheet 212, and a first middle portion 213 connecting the first conductive sheet 211 and the second conductive sheet 212. The first conductive sheet 211 and the second conductive sheet 212 are arranged at intervals along the first direction A1-A1 (for example, the front-to-back direction). In an application mode of the present invention, the first conductive sheet 211 is configured to contact with a docking connector (not shown), and the second conductive sheet 212 is configured to be electrically connected (for example, welded) to a cable (not shown). The first middle portion 213 includes a first embedded portion 2130 embedded in the insulating body 1 and away from the first conductive sheet 211 along the second direction A2-A2 (for example, the up-down direction). The second direction A2-A2 is perpendicular to the first direction A1-A1.
[0087] The insulating body 1 includes a first surface 11 and a second surface 12 opposite to the first surface 11 along the second direction A2-A2. In the illustrated embodiment of the present invention, the first conductive sheet 211 and the second conductive sheet 212 are both exposed to the first surface 11. In one embodiment of the present invention, the first outer surface 2111 (e.g., upper surface) of the first conductive sheet 211 and the second outer surface 2121 (e.g., upper surface) of the second conductive sheet 212 are located in the same plane. In another embodiment of the present invention, the first outer surface 2111 of the first conductive sheet 211 and the second outer surface 2121 of the second conductive sheet 212 may also be located in different planes. The first middle portion 213 extends from the first surface 11 to the second surface 12 along the second direction A2-A2. In the illustrated embodiment of the present invention, the insulating body 1 includes a first covering portion 13 covering the first middle portion 213, and the first covering portion 13 is located between the first conductive sheet 211 and the second conductive sheet 212 along the first direction A1-A1. The first conductive sheet 211, the first covering portion 13 and the second conductive sheet 212 are generally flat. A person skilled in the art will understand that slight undulations among the first conductive sheet 211, the first covering portion 13 and the second conductive sheet 212, including but not limited to those caused by manufacturing errors, are still considered to be "generally flat". The first covering portion 13 is provided with a third outer surface 131. Preferably, the third outer surface 131 of the first covering portion 13, the first outer surface 2111 of the first conductive sheet 211 and the second outer surface 2121 of the second conductive sheet 212 are located in the same plane.
[0088] In addition, in the illustrated embodiment of the present invention, the second conductive sheet 212 is deflected outward along a third direction A3-A3 (e.g., left-right direction) compared to the first conductive sheet 211, and the third direction A3-A3 is perpendicular to the first direction A1-A1 and the second direction A2-A2. Among the plurality of first conductive terminals 21, the distance occupied by the second conductive sheet 212 along the third direction A3-A3 is greater than the distance occupied by the first conductive sheet 211 along the third direction A3-A3. With such a configuration, when the second conductive sheet 212 is welded to the cable, the risk of a short circuit due to too small a spacing between the second conductive sheets 212 can be reduced.
[0089] In the illustrated embodiment of the present invention, the plurality of first conductive terminals 21 include a first signal terminal S1, a second signal terminal S2, a first ground terminal G1, and a second ground terminal G2, wherein the first signal terminal S1 and the second signal terminal S2 are adjacently arranged along the third direction A3-A3 and form a first signal terminal group, the first ground terminal G1 is located on one side of the first signal terminal group along the third direction A3-A3, and the second ground terminal G2 is located on the other side of the first signal terminal group along the third direction A3-A3. The terminal layout of G1-S1-S2-G2 of the present invention is conducive to improving the quality of signal transmission. In the illustrated embodiment of the present invention, in order to provide a better grounding shielding effect, the first conductive sheet 211 of the first ground terminal G1 and the first conductive sheet 211 of the second ground terminal G2 both extend forward along the first direction A1-A1 beyond the first conductive sheet 211 of the first signal terminal S1 and the first conductive sheet 211 of the second signal terminal S2.
