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 backboard connector. The high-speed backboard connector specifically comprises a connector shell, a first shielding sheet, a second shielding sheet, and a first grounding contact and a second grounding contact, wherein a plugging module is installed in the connector shell, the plugging module comprises contact pieces arranged in rows, and the contact pieces arranged in rows comprise differential signal pairs and grounding contact pieces; the first shielding sheet and the second shielding sheet are arranged opposite to the row of contact pieces at intervals, and a first grounding contact and a second grounding contact which protrude towards the grounding contact pieces are arranged at the positions, corresponding to the grounding contact pieces, of the first shielding sheet and the second shielding sheet respectively; and the first grounding contact and the second grounding contact are both located on the opposite sides of the grounding contact piece, an inserting space allowing the grounding contact piece of the adaptive connector to be inserted therein is formed between the first grounding contact and the grounding contact piece, and the first grounding contact and the second grounding contact are arranged at intervals in the inserting direction. According to the high-speed backboard connector disclosed by the invention, the contact between different grounding contacts and the grounding contact piece is ensured, and meanwhile, the different grounding contacts are arranged at intervals in the plugging direction, so that the stub effect is weakened, and the signal transmission quality of the high-speed backboard connector is ensured.

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...
