specific Embodiment 1

[0067] like Figure 1 to Figure 14 As shown, in this embodiment, the orthogonal connector is taken as an example to illustrate the related structure of the connector. The mating connector is mounted on the second circuit board when in use, and the first circuit board and the second circuit board are arranged orthogonally. The orthogonal connector includes a housing 100 in which multiple (at least two) wafers 200 are arranged. There are signal terminals 204 and grounding terminals 205 in the housing 100. The signal terminals 204 and grounding terminals 205 are installed at one end when in use. On the first circuit board, the other end is used to insert the signal terminal and the ground terminal in the matching connector.

[0068] The structure of wafer 200 is as image 3 and Figure 4 As shown, the chip 200 includes an insulating frame 203 on which three signal differential pairs and three ground terminals 205 are fixed. The signal differential pairs and the ground terminal...

Embodiment 1

[0090] In Embodiment 1, the grounding column is a rectangular column. In this embodiment, the shape of the ground post may be cylindrical or other shapes.

specific Embodiment 3

[0092] In Embodiment 1, the grounding post is inserted into the grounding contact socket, and the end surface of the grounding post is flush with the surface of the separator. In this embodiment, the end surface of the grounding post may be located inside the grounding contact socket in the partition. Alternatively, in other embodiments, the grounding post may not be inserted into the grounding contact socket, that is, the grounding contact socket is small, and the grounding post is located at one side of the grounding contact socket.

Abstract

The invention relates to the technical field of signal transmission, in particular to a connector which comprises a shell. A wafer is arranged on the shell, the wafer comprises an insulating frame, the insulating frame is provided with a signal differential pair and a grounding terminal, the signal differential pair comprises two signal terminals, the signal terminals and the grounding terminal are respectively provided with matching ends, each signal terminal comprises a signal contact located at the matching end, and the grounding terminal comprises a grounding contact located at the matching end; the connector also comprises a shielding net, the shielding net is provided with a signal contact through hole and a grounding contact through hole, and the grounding contact is electrically contacted with the hole wall of the grounding contact through hole. The shell is provided with a signal contact jack corresponding to the signal contact through hole, and is provided with a grounding contact jack corresponding to the grounding contact through hole. An insulated clamping bulge is arranged on the shell; the signal contact through hole is matched and clamped with a clamping bulge; the clamping bulge is used for separating the signal contacts from the shielding net to prevent the signal contacts from making contact with the shielding net.

Description

technical field [0001] The invention relates to the technical field of signal transmission, in particular to a connector. Background technique [0002] With the continuous improvement of signal transmission rate, the design requirements for electrical connectors are also continuously improved. Usually, shielding nets are added to the housing to prevent signal crosstalk and improve signal transmission quality. [0003] As shown in the electrical connector disclosed in the Chinese invention patent application with the application publication number CN110391550A, the electrical connector includes a housing in which multiple pairs of wafers (that is, the signal contact module in the patent) are arranged. Shielding net for shielding at the plug-in position. Among them, the chip includes an insulating frame fixed on the shell, and the insulating frame is provided with signal differential pairs and ground terminals. The mating end, the signal terminal includes a signal contact lo...
