specific Embodiment 1

[0083] Such as Figure 3 to Figure 11 As shown, the connector includes a bent female 200 and a straight male 300 that are mated to each other.

[0084] The structure of bending mother 200 is as follows Figure 3 to Figure 10 As shown, the bend female 200 includes an insulator 201 , and a plurality of (at least two) terminal modules 202 are sequentially arranged in the insulator 201 , and each terminal module 202 is arranged sequentially along the thickness direction of the terminal module 202 . Wherein, the structures of the terminal modules 202 are similar, and only one of them is taken as an example for illustration below.

[0085] The structure of the terminal module 202 is as Figure 5 to Figure 10 As shown, the terminal module 202 includes a primary injection molding body 2021, and the primary injection molding body 2021 includes ground terminals and signal differential pairs arranged alternately in sequence, wherein the signal differential pair includes two signal term...

Embodiment 1

[0100] In Embodiment 1, claws are provided on the sheet-shaped main body, and perforations are provided on the primary injection-molded body, so as to realize clamping of the sheet-shaped main body and the primary injection-molded body. In this embodiment, the positions of the claws and the perforations can be interchanged, for example, the claws are pre-embedded during the molding of an injection molded body.

[0101] In other embodiments, the assembly method between the sheet-shaped main body and the primary injection molding body can be changed according to actual conditions, for example, one-piece casting can still be selected.

specific Embodiment 3

[0103] In Embodiment 1, the filter protrusion is a bulge formed by stamping in one piece. Wherein, the shape of the bulge can be changed according to the actual situation, for example, it can be a regular or irregular shape such as a circle or a rectangle.

[0104] In other embodiments, the molding method of the filter protrusions can be changed, for example, additional bumps provided on the sheet-shaped main body and the like.

Abstract

The invention relates to a shielding sheet and a terminal module and a connector using the shielding sheet. The shielding sheet includes a sheet-shaped main body and a filter protrusion, which is arranged on the front end of the sheet-shaped main body; Adaptive signal contacts are arranged at intervals and form filter capacitors. When in use, a filter capacitor is formed between the filter protrusion and the adaptive signal contact, which can play a good filtering role, absorb the radiation of the adaptive signal contact through the filter capacitor, and weaken the radiation intensity of the adaptive signal contact, effectively It avoids the signal common path between two adjacent signal differential pairs, improves the resonance condition of the bonding area in the connector, and effectively reduces the crosstalk value of the bonding area, thereby improving the signal transmission quality.

Description

technical field [0001] The invention relates to a shielding sheet, a terminal module and a connector using the shielding sheet. Background technique [0002] In modern data communication transmission systems, the transmission rate is getting higher and higher. High-speed interconnection systems are widely used in communication networks and data exchange systems. As the core bridge of data communication, high-speed backplane connectors have higher and higher performance requirements. The application of various forms of shielding sheet greatly reduces crosstalk, improves the SI performance (signal integrity) of the high-speed backplane connector, and can meet the higher-speed transmission requirements. [0003] Existing high-speed backplane connectors include two ends that are mated to each other, one of which is a bent plug-in end, and the other end is a mating end. The adapted end includes adapted signal contacts and adapted ground contacts. The bent plug end includes an i...
