The ground terminal includes a plurality of first ground terminals G1 and a plurality of second ground terminals G2. Each differential pair DP has a first ground terminal G1 and a second ground terminal G2 on each side to improve the signal transmission quality.

[0056] In the embodiment illustrated in this utility model, the first signal terminal S1 includes a first fixing portion 111 fixed in the insulating block 2, a first contact spring arm 112 extending from one end of the first fixing portion 111 along the first direction A1-A1, and a first welding portion 113 extending from the other end of the first fixing portion 111 along the first direction A1-A1.

The first welding portion 113 extends to the other side, protruding from the insulating block 2. The first contact spring arm 112 is provided with a first contact portion 1121.

[0057] Similarly, in the embodiment illustrated in this utility model, the second signal terminal S2 includes a second fixing portion 121 fixed in the insulating block 2, a second contact spring arm 122 extending from one end of the second fixing portion 121 along the first direction A1-A1, and a second welding portion 123 extending from the other end of the second fixing portion 121 along the first direction A1-A1.

The second welding portion 123 extends to the other side, protruding from the insulating block 2. The second contact spring arm 122 is provided with a second contact portion 1221.

[0058] The first grounding terminal G1 includes a first retaining portion 131 fixed in the insulating block 2, a first abutting spring arm 132 extending from one end of the first retaining portion 131 along the first direction A1-A1, and a first tail portion 133 extending from the other end of the first retaining portion 131 along the first direction A1-A1. The first abutting spring arm 132 extends cantileveredly to one side, protruding from the insulating block 2. The first tail portion 133 extends to the other side, protruding from the insulating block 2. The first abutting spring arm 132 is provided with a first abutting portion 1321.

[0059] Specifically, in the embodiment illustrated in this utility model, the first abutting arm 132 includes a first bullet arm 132a, a second bullet arm 132b, and a connecting portion 132c connecting the first bullet arm 132a and the second bullet arm 132b.

The second tail portion 143 extends to the other side, protruding from the insulating block 2. The second abutting spring arm 142 is provided with a second abutting portion 1421.

[0062] Those skilled in the art will understand that the structure of the second grounding terminal G2 may be the same as or different from the structure of the first grounding terminal G1, and this utility model will not elaborate further.

[0063] The insulating block 2 is provided with a plurality of grooves 21 to cooperate with the first shielding sheet 41. In the embodiment illustrated in this utility model, the insulating block 2 fills part of the slot 132d.

[0064] Please combine Figure 11 as well as Figure 18As shown, the cable 3 includes a first conductor 31, a second conductor 32, a first insulating layer 33 at least partially wrapped around the first conductor 31 circumferentially, a second insulating layer 34 at least partially wrapped around the second conductor 32 circumferentially, a shielding layer 35 located outside the first insulating layer 33 and the second insulating layer 34, and an outermost insulating sheath 36. The shielding layer 35 includes, but is not limited to, a metal braided mesh. The first conductor 31 is electrically connected (e.g., welded) to the first solder joint 113 of the first signal terminal S1, and the second conductor 32 is electrically connected (e.g., welded) to the second solder joint 123 of the second signal terminal S2. The outer insulating block 5 covers the solder joint between the first conductor 31 and the first solder joint 113, and also covers the solder joint between the second conductor 32 and the second solder joint 123 to improve structural strength.

[0065] Please combine Figures 1 to 13 As shown, the first shielding sheet 41 is a metal shielding sheet, meaning it is made of metal. The first shielding sheet 41 includes a first base 411, a protrusion 412, and a connecting portion 413 connecting the first base 411 and the protrusion 412. The first base 411 includes a first mating portion 4111, a second mating portion 4112, and a first protrusion 4113 connecting the first mating portion 4111 and the second mating portion 4112. The first protrusion 4113 at least partially covers the cable 3 and is connected to the shielding layer 35. In the embodiment illustrated in this utility model, the first protrusion 4113 has a first opening 4113a and a slot 4113b to adjust impedance. The shielding layer 35 is at least exposed in the first opening 4113a, which accommodates solder, connecting the shielding layer 35 to the first protrusion 4113. Both the first conductor 31 and the second conductor 32 are exposed in the slot 4113b. The outer insulating block 5 at least partially fills the slot 4113b to adjust the impedance. In the embodiment illustrated in this utility model, the outer insulating block 5 is provided with a notch 51 corresponding to the slot 4113b. The connecting portion 413 is at least partially received in the groove 21.

The clearance portion 4121 protrudes away from the first signal terminal S1 and the second signal terminal S2, thereby avoiding short circuits due to contact with the first signal terminal S1 and the second signal terminal S2.

[0066] The first transition portion 4124 has a first inclined surface 4124a, and the second transition portion 4125 has a second inclined surface 4125a, such that the width of the first extension portion 4122 along the first direction A1-A1 and the width of the second extension portion 4123 along the first direction A1-A1 are both smaller than the width of the clearance portion 4121 along the first direction A1-A1. By narrowing the design of the first extension portion 4122 and the second extension portion 4123, it is beneficial to improve the reliability of the contact between the first shielding plate 41 and the first grounding terminal G1 and the second grounding terminal G2 when the terminal module 10 is electrically connected to the docking element 200.

[0067] Please combine Figure 9 as well as Figure 21 As shown in the illustrated embodiment of this utility model, when the terminal module 10 is not engaged with the docking element 200, there is a first distance D1 between the first extension 4122 and the first abutment spring arm 132, and a second distance D2 between the second extension 4123 and the second abutment spring arm 142. Those skilled in the art will understand that when the terminal module 10 is not engaged with the docking element 200, the first shielding plate 41 does not restrict the deformation of the first abutment spring arm 132 and the second abutment spring arm 142, thereby reducing the abutment force and facilitating installation.

[0068] In one embodiment of this utility model, the docking element 200 is provided with a plurality of conductive sheets (not shown) on its surface, the conductive sheets being configured to abut against the first contact portion 1121, the second contact portion 1221, the first abutting portion 1321, and the second abutting portion 1421. Please refer to... Figure 22 As shown, when the terminal module 10 is engaged with the docking element 200, the first abutting spring arm 132 and the second abutting spring arm 142 are configured to abut against the docking element 200 and undergo elastic deformation, so that the first abutting spring arm 132 and the second abutting spring arm 142 respectively contact the first extension 4122 and the second extension 4123 to improve the grounding shielding effect.

[0069] In the embodiment illustrated in this utility model, the cable 3 is clamped between the first shielding plate 41 and the second shielding plate 42. The second shielding plate 42 is provided with a second base 421, which includes a third mating portion 4211, a fourth mating portion 4212, and a second protrusion 4213 connecting the third mating portion 4211 and the fourth mating portion 4212. The first mating portion 4111 is welded to one surface of the first tail portion 133 (e.g., spot welded), and the second mating portion 4112 is welded to one surface of the second tail portion 143 (e.g., spot welded). The third mating portion 4211 is welded to the other surface of the first tail portion 133 (e.g., spot welded), and the fourth mating portion 4212 is welded to the other surface of the second tail portion 143 (e.g., spot welded).

[0070] Those skilled in the art will understand that, in the embodiments illustrated in this utility model, the first shielding plate 41, the second shielding plate 42, the first grounding terminal G1, and the second grounding terminal G2 together form a surrounding shielding space, and the first signal terminal S1 and the second signal terminal S2 are at least partially located in the shielding space, thereby reducing signal crosstalk and improving the quality of signal transmission.

[0071] The terminal module 10 of this invention is provided with a shielding plate 4, which has a first extension 4122 and a second extension 4123 corresponding to the first abutment spring arm 132 and the second abutment spring arm 142, respectively. When the terminal module 10 is not engaged with the docking element 200, the first abutment spring arm 132 and the second abutment spring arm 142 do not contact the first extension 4122 and the second extension 4123. When the terminal module 10 is engaged with the docking element 200, the first abutment spring arm 132 and the second abutment spring arm 142 are configured to abut against the docking element 200 and undergo elastic deformation, so that the first abutment spring arm 132 and the second abutment spring arm 142 contact the first extension 4122 and the second extension 4123, respectively. With this configuration, the shielding plate 4 of this invention will not have an excessive impact on the elastic deformation of the first abutment spring arm 132 and the second abutment spring arm 142, thus improving installation convenience. In addition, the design of the shielding sheet 4 has good flexibility and is conducive to increasing the shielding area of ​​the shielding sheet 4, which further improves the shielding effect.

[0072] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. The understanding of the present utility model should be based on those skilled in the art. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present utility model.
