The insulating material allows the first component 12 and the second component 14 to be coupled together without separating the first component 12 and the second component 14. In another embodiment, the third component 16 can also be a prefabricated component that is used to snap fit the first component 12 and the second component 14 together without separating the first component 12 and the second component 14.

[0096] In another embodiment, referring to Figure 1 In addition to being coupled to the first through-hole 128 and the second through-hole 147, the third component 16 can also be disposed on the front edge of the first component 12 and the second component 14.

[0098] 5(a) and 5(b) are schematic diagrams illustrating the first common ground terminal and the first signal terminal of the present invention. FIG. 5(a) is a perspective schematic diagram illustrating the first common ground terminal and the first signal terminal of the present invention; and FIG. 5(b) is a perspective schematic diagram illustrating the first common ground terminal of the present invention.

[0099] The first common ground terminal 1822 includes a first ground terminal 18222, a first U-shaped bent member 18224, a first common ground plate 18226, and a first extended contact 18228. The number of first ground terminals 18222, first U-shaped bent member 18224, and first extended contact 18228 is illustrated as three. Each of the first U-shaped bent members 18224 connects each of the first ground terminals 18222 to the first common ground plate 18226, and one end of each of the first extended contacts 18228 connects to the free end 18226' of the first common ground plate 18226, while the other end of each of the first extended contacts 18228 connects to the first ground terminal 18222. Furthermore, the number of first signal terminals 1824 is illustrated as four. Two first signal terminals 1824 are disposed between the two first ground terminals 18222, respectively. It is worth noting that the first common ground terminal 1822 is formed after the first grounding terminal 18222 and the first common ground plate 18226 are formed, and the first common ground plate 18226 is bent to form a U-shaped first common ground terminal 1822, so as to increase the grounding area so that it can be used to transmit high-frequency signals; in addition, the first extended contact piece 18228 also connects the first common ground terminal 1822 and the first extended contact piece 18228 to form a grounding loop, thereby improving the anti-noise effect.

FIG6(a) is a perspective schematic diagram illustrating the second common ground terminal, second signal terminal, and fixing member of the present invention; and FIG6(b) is a perspective schematic diagram illustrating the second common ground terminal of the present invention.

[0101] The second terminal assembly 20 includes a second common ground terminal 202 and a second signal terminal 204. The second common ground terminal 202 is disposed in the second ground terminal slot 142 and the second common ground terminal slot 146, and the second signal terminal 204 is disposed in the second signal terminal slot 144. The second common ground terminal 202 is an integrally formed structure. The second common ground terminal 202 further includes a second ground terminal 2022, a second U-shaped bend 2024, a second common ground plate 2026, and a second extended contact 2028. The number of second ground terminals 2022, second U-shaped bend 2024, and second extended contact 2028 is illustrated as a plurality. Each of the second U-shaped bent members 2024 connects each of the second ground terminals 2022 to the second common ground plate. One end of each of the second extended contacts 2028 is connected to the free end 2026' of the second common ground plate 2026, and the other end of each of the second extended contacts 2028 is connected to each of the second ground terminals 2022. Furthermore, the second signal terminals 204 and the second ground terminals 2022 are arranged alternately. It is noteworthy that the second common ground terminal 202 is formed by bending the second common ground plate 2026 after forming the second ground terminals 2022 and the second common ground plate 2026 to form a U-shaped structure. This increases the grounding area for high-frequency signal transmission. Furthermore, the second extended contacts 2028 also connect the second common ground plate 2026 and the second extended contacts 2028 to form a ground loop, thereby improving noise immunity.

[0102] The fixing member 22 is disposed on the second component 14 to secure the second component 14 to an external printed circuit board.

The fixing member 22 is disposed in the accommodating space 1416, with a portion of the fixing member 22 protruding from the second opening 1412.

[0103] For reference Figure 7 , is a side view illustrating the first common ground sheet contacting the second common ground sheet of the present invention. Figure 7 After the first component 12 is combined with the second component 14, the first common ground terminal 1822 contacts the second common ground terminal 202, and in particular, the first common ground piece 18226 contacts the second common ground piece 2026, which can further increase the grounding area.

[0104] In another embodiment, the first component 12 forms a first positioning post 1212 and a third positioning post 1214, and the second component 14 forms a second positioning slot 148 and a fourth positioning slot 1410. It is noteworthy that the second positioning slot 148 and the fourth positioning slot 1410 extend and protrude from the second insulator 141, respectively, forming a second positioning slot 148' and a fourth positioning slot 1410' that appear to be protruding. By inserting the first positioning post 1212 into the second positioning slot 148 and the third positioning post 1214 into the fourth positioning slot 1410, the first component 12 is positioned within the second component 14, thereby coupling the first and second components 12 and 14. In this embodiment, the shape of the second positioning groove 148 differs from the shape of the fourth positioning groove 1410. For example, the second positioning groove 148 is a cylindrical groove, and the fourth positioning groove 1410 is a hexagonal column groove. The different shapes can achieve the purpose of preventing objects from being inserted (or preventing fooling), allowing the second positioning groove 148 to accommodate the first positioning post 1212 and the fourth positioning groove 1410 to accommodate the third positioning post 1214. In another embodiment, the shape of the first positioning post 1212 can be different from the shape of the third positioning post 1214, so that the first positioning post 1212 can be inserted into the second positioning groove 148 and the third positioning post 1214 can be inserted into the fourth positioning groove 1410.
