specific Embodiment 1

[0033] This embodiment of the high-speed backplane connector incorporates Figure 3-5 for clarification, since Figure 3-5 Both show a schematic diagram of the mating state of the high-speed backplane connector and the adapter connector. In order to clearly distinguish the high-speed backplane connector and the adapter connector, the high-speed backplane connector of this embodiment is referred to as It is a female connector, and the mating connector is called a male connector.

[0034]The female end connector of this embodiment includes a connector housing, and a plurality of plug-in modules 1 are stacked and installed in the connector housing. The plug-in module 1 has an insulator, and contacts arranged in rows are fixedly installed in the insulator. , including a plurality of differential signal pairs arranged at intervals and a female ground contact 12 disposed between two adjacent differential signal pairs. These contacts protrude from one side of the insulator to form ...

Abstract

The invention relates to a high-speed backplane connector. It specifically includes: a connector housing in which a plug-in module is installed, the plug-in module includes contacts arranged in rows, and the rows of contacts include differential signal pairs and ground contacts; the first shielding sheet and the second shielding sheet , are arranged at intervals relative to the rows of contacts, on which there are respectively provided a first ground contact and a second ground contact protruding toward the ground contact at positions corresponding to the ground contact; the first and second ground The contacts are all on the opposite side of the ground contact, and form an insertion space for the ground contact of the adapter connector to be inserted between the ground contact, and the first ground contact and the second ground contact are mated. Arranged at intervals in the direction. The high-speed backplane connector of the present invention ensures the contact between different grounding contacts and grounding contacts. Signal transmission quality.

Description

technical field [0001] The invention relates to the field of connectors, in particular to a high-speed backplane connector. Background technique [0002] Due to structural limitations in high-speed backplane connectors, the crosstalk between differential signal pairs is serious, which greatly affects the quality of signal transmission. With the increase of the transmission rate of the backplane connector, in order to ensure that the connector has a good return path and less crosstalk, the signal return path is shortened by changing the structure of the shielding sheet and the contact mode of the shielding sheet in the mating area. Improve high-speed performance. [0003] There are two common approaches. The first such as figure 1 As shown, the backplane connector 1 has a female ground contact 12 protruding from the mating area to be mated with the mated male ground contact 22, and the backplane connector 1 is connected to the female ground contact 12 The female end shiel...
