[0031] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] To address the problem that traditional signal modules are prone to relative movement, affecting terminal mating performance, this application provides a connector 10 that reduces or even eliminates displacement between adjacent signal modules 11 through a connection structure.

[0033] Please refer to Figure 1 The connector 10 includes a plurality of contact module groups 1 arranged in a plurality of arrangement. For ease of understanding, the direction in which the plurality of contact module groups 1 are arranged is defined as the first direction X. Each contact module group 1 includes a pair of signal modules 11 arranged along the first direction X. The signal module 11 includes a plurality of terminals 111 extending along the second direction Y and spaced apart along the third direction Z, and an insulating sheet 112 formed on the terminals 111. The first direction X, the second direction Y and the third direction Z are orthogonal to each other.

[0034] Adjacent signal modules 11 are connected by a connection structure to form a stable contact module group 1. The connection structure makes the adjacent signal modules 11 form a stable contact module group 1, reducing the relative movement between adjacent signal modules 11, thereby reducing the positional misalignment of the terminals 111 within the signal module 11 relative to the component contacts, and improving the docking accuracy and docking stability of the connector 10.

[0035] In some embodiments, please refer to Figures 1-3 Two signal modules 11 are defined as a first signal module 113 and a second signal module 114, respectively, which carry signals with opposite phases and the same amplitude. The connection structure includes, but is not limited to, interlocking connection, hook connection or adhesive connection, which can be selected according to actual needs.

[0036] Optional, please refer to Figure 4In this application, the first signal module 113 and the second signal module 114 are connected by a first fitting structure 2. The first fitting structure 2 includes a first protrusion 21 and a first groove 22. The first protrusion 21 is distributed on the side of the first signal module 113 facing the second signal module 114 and extends along the first direction X. The first groove 22 is distributed on the side of the second signal module 114 facing the first signal module 113 and is recessed along the first direction X. At least part of the first groove 22 penetrates the first signal module 113 and the second signal module 114 along the first direction X, so that the first signal module 113 and the second signal module 114 are connected by the cooperation of the first protrusion 21 and the first groove 22. By adopting the connection structure of the first protrusion 21 and the first groove 22, the relative movement of the first signal module 113 and the second signal module 114 along the second direction Y and the third direction Z can be restricted by geometric constraints; and the through-type setting of at least part of the first groove 22 can increase the docking length of the first protrusion 21 and the first groove 22, further improving the docking stability between the signal modules 11.

The extension 211 is configured to extend along a second direction Y and connect the fitting portion 212 to the wall of the first groove 22. The fitting portion 212 is configured to extend along a first direction X and embed into the first groove 22, thereby allowing the first signal module 113 and the second signal module 114 to fit together. The first protrusion 21 and the first groove 22 on both the first signal module 113 and the second signal module 114 further improve the connection stability between them.

The contact portion 1111 is used for signal connection with the component, the exposed middle portion 1112 is used for various processes in the production and testing process, and the mounting portion 1113 is used for mounting the connector 10 on the component. The insulating sheet 112 of the signal module 11 includes a discretely arranged first part 1121, a second part 1122 and a third part 1123. All three parts are formed with the aforementioned terminals 111 and are provided with a first fitting structure 2. The first groove 22 exposes at least part of the middle part 1112, which facilitates various processes in the production and testing of the connector 10. During assembly, the first protrusion 21 can be embedded in the first groove 22 to cover the exposed terminals 111, reduce the impedance and loss of the connector 10 during application, and improve the transmission performance of the connector 10.

The signal module 11 and the grounding module 12 are connected by the cooperation of the second protrusion 31 and the second groove 32. By adopting the connection structure of the second protrusion 31 and the second groove 32, the relative movement of the signal module 11 and the grounding module 12 along the second direction Y and the third direction Z can be restricted by geometric constraints. Meanwhile, by setting the grounding module 12, the grounding module 12 restricts the movement of the first signal module 113 and the second signal module 114 along the first direction X.
