specific Embodiment 1

[0052] Such as Figure 1 to Figure 6 As shown, the socket of the high-speed connector includes an insulator 1 , which is U-shaped as a whole, and includes two risers 9 opposite to each other and a bottom plate 10 connecting the two risers 9 . Such as image 3 As shown, the bottom plate 10 is provided with terminal fixing holes 5 arranged in a row and shielding member fixing holes arranged in a row corresponding to the terminal fixing holes 5. The terminal fixing holes 5 correspond to the shielding member fixing holes one by one and are all through holes. Signal terminals 2 are inserted in the terminal fixing holes 5 , and the signal terminals are arranged in pairs for signal transmission; shielding pieces for shielding the signal terminals 2 are inserted in the fixing holes of each shielding piece. In this embodiment, the shield includes a first-type shield and a second-type shield. Correspondingly, the shield fixing hole on the insulator 1 for the first-type shield 3 to be i...

Embodiment 2

[0058] The difference between this embodiment and the above-mentioned embodiment 1 is that the escape groove is arranged on the embedded part and penetrates through the end face of the end of the embedded part away from the overhanging part, so that the end of the avoidance groove close to the overhanging part is a blind end; If the protruding side of the overhanging part is the front side of the insulator, at this time, the entire second-type shield can be inserted into the fixing hole of the second-type shield from front to back, and correspondingly, the blind end is stopped at The front side of the middle connecting part.

Embodiment 3

[0060] The difference between this embodiment and the above-mentioned embodiment 1 is that there is no space between the two sides of the overhanging part of the sheet-shaped shielding part of the second type shielding part and the overhanging part of the C-shaped shielding part. The body as a whole has a rectangular tubular structure with a rectangular cross-section. In order to ensure the good assembly of the second type of shielding, the fixing hole of the second type of shielding is a ring structure and is a blind hole, and only the bottom of the hole is provided for the second type of shielding. The fisheye goes through the perforation.

Abstract

The invention relates to a socket of a high-speed connector. The socket of the high-speed connector comprises an insulator, signal terminals and shielding pieces are fixed on the insulator, at least one column of signal terminals is arranged, and the shielding pieces are distributed in columns corresponding to the signal terminals; the shielding pieces comprise first type shielding pieces and second type shielding pieces, the first type shielding piece is provided with a lateral opening, and the lateral opening faces one end of the arrangement direction of the shielding piece; the second typeshielding piece is located at the tail end of the corresponding column and corresponds to the lateral opening of the adjacent first type shielding piece; the second type shielding piece comprises a shielding body used for surrounding the corresponding signal terminal; and the side shielding bodies of the second type shielding piece are connected into a whole. The signal terminals on the socket ofthe high-speed connector are shielded in all directions, so that the signal integrity of the whole transmission line is ensured, and the crosstalk problem in the high-speed connector is improved.

Description

technical field [0001] The invention relates to the field of conductive connection, in particular to a socket of a high-speed connector. Background technique [0002] Crosstalk refers to the undesired voltage noise interference on adjacent transmission lines due to electromagnetic coupling when signals are transmitted on transmission lines. Excessive crosstalk will have two harmful effects: First, crosstalk will change the effective characteristic impedance and transmission speed of the transmission line, affecting the signal integrity of the system, thereby changing the transmission performance of the transmission line; second, crosstalk will be in other Induced noise is introduced on the transmission line, further degrading signal integrity and reducing noise margins. Therefore, reducing crosstalk has always been an important direction involved in high-speed connectors. [0003] In order to reduce crosstalk, existing connectors use various methods to shield the transmiss...
