AI Technical Summary

Technical Problem

Existing high-speed cable connection structures cause mismatches in wire pair lengths during twisting, resulting in delay differences within differential pairs and between wire pairs, which affect data transmission characteristics. Furthermore, the shielding layer has insufficient anti-crosstalk capability, and the core wires are easily deformed when the connector is plugged in, unplugged, or pulled, affecting the high-frequency signal transmission performance.

Method used

A cylindrical cable holder is used, which forms an interference fit between the cylindrical body and the shielding layer. The plug pins contact the terminal block to ensure that the cable holder completely covers the shielding layer, prevents core wire deformation, enhances anti-crosstalk capability, and forms a stable grounding loop on the terminal block.

Benefits of technology

It effectively prevents the core wire length from remaining consistent when the cable is plugged in or pulled by the connector, reduces transmission delay, improves high-frequency signal transmission performance, enhances anti-interference capability, and ensures the stability and integrity of high-speed data transmission.

Abstract

This utility model discloses a connection structure with high-frequency gain performance, including a terminal block; a cable holder, which includes a cylindrical body and a plug pin, one end of which is connected to the cylindrical body, and the other end of which is plugged into the terminal block to form a grounding loop; and a cable, which includes a plastic layer, a shielding layer, and several terminals, with the shielding layer partially exposed above the plastic layer. The cylindrical body wraps around the exposed portion of the shielding layer and forms electrical contact with it. The terminals pass through the cylindrical body and connect to the terminal block, and the cylindrical body secures the cable. By making the cable holder cylindrical, this application ensures that the cable holder completely covers the shielding layer and secures the cable. This not only enhances the crosstalk immunity between cables but also prevents cable stretching, twisting, or bending during repeated plugging and unplugging of the connector or improper pulling. This ensures that the core wires of the cables maintain consistent length and prevents transmission delay during high-frequency signal transmission.
