Abstract
Description

[0002] With the booming development of the communications industry, various connection interfaces are constantly pursuing more reliable and stable connection structures. At the same time, signal transmission rates are continuously increasing. Taking the PCIe interface as an example, PCIe 3.0 has a transmission rate of 8GT / s, PCIe 4.0 has a transmission rate of 16GT / s, PCIe 5.0 has a transmission rate of 32GT / s, and PCIe 6.0 has a transmission rate of 64GT / s.

[0027] Please see Figure 1 , Figure 1 This is a three-dimensional assembly structure diagram of the terminal module 10 embodiment provided in this application. The terminal module 10 in this embodiment includes a base assembly 11, a terminal assembly 12, and a grounding assembly 13.
[0028] Please refer to the following: Figure 2 and Figure 3 , Figure 2 yes Figure 1 An exploded three-dimensional structural diagram of the middle terminal module 10. Figure 3 yes Figure 1 A schematic diagram of the cross-section of the middle terminal module 10 in the FF direction.
[0029] The base assembly 11 includes a first base 111 and a second base 112. The first base 111 and the second base 112 are arranged opposite to each other. In practical applications, both the first base 111 and the second base 112 are injection molded and have the same structure.

[0032] In this embodiment, the spacer 131 is electrically connected to a plurality of first terminals 121 and a plurality of second terminals 122 respectively. The number of first grounding elements 132 and second grounding elements 133 are both multiple. The plurality of first grounding elements 131 are electrically connected to a plurality of first terminals 121 respectively, and the plurality of second grounding elements 132 are electrically connected to a plurality of second terminals 122 respectively.
[0033] Please refer to the following: Figure 3 and Figure 4 , Figure 4 yes Figure 3Schematic cross-sectional view of the first base 111, the first terminal 121, and the first ground connection member 132. Among them, the first terminal 121 and the second terminal 122 respectively include a first grounding portion 1211, a second grounding portion 1212, and a third grounding portion 1213 that are connected in sequence. The spacer 131 is electrically connected to the first grounding portion 1211 of the first terminal 121 and the first grounding portion of the second terminal 122. In practical applications, the first grounding portion 1211 of the first terminal 121 can be welded to the spacer 131, and the first grounding portion of the second terminal 122 can be welded to the spacer 131.

The connecting body 1322 of the second grounding element 133 is attached to the second terminal 122, so that the second grounding element 133 and the first terminal 122 are in contact, thereby achieving grounding.
[0040] It is understood that the first ground string 132 and the second ground string 133 have the same structure in this embodiment. The illustrations in this embodiment only use the first ground string 132 as an example. The description of the first ground string 132 also applies to the second ground string 133.
[0041] Optionally, the number of hot-melt holes 102 can be multiple, increasing the structural robustness of the first ground string 132 and the first base 111, and the structural robustness of the second ground string 133 and the second base 112. For example, in this embodiment, the number of hot-melt holes 102 is two. The number of connecting bodies 1322 can be multiple, increasing the contact stability of the first ground string 132 and the first terminal 121, and the contact stability of the second ground string 133 and the second terminal 122. For example, in this embodiment, the number of connecting bodies 1322 is four.
