Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic device technology, and more particularly to a connector. Background Technology
[0002] PCI Express (Peripheral Component Interconnect Express), abbreviated as PCI E (or PCIe), is a next-generation bus interface. Proposed by Intel (its earliest name was also "3GIO," signifying the third-generation I / O interface), PCI E is a high-speed serial interface that uses differential signals and supports hot-swapping. It has become the standard interface for connecting high-speed components to the motherboard using a point-to-point access bus. Currently, the PCIe interface has evolved to the latest 5th generation, abbreviated as PCIe 5.0. PCIe 5.0 has twice the bandwidth of PCIe 4.0, supporting data link speeds of up to 32GT / s, and is backward compatible. It is widely used in PCs, solid-state drives, servers, workstations, etc.
[0003] In addition to increased bandwidth, CIE 5.0 specifications include electrical enhancements to improve signal integrity and mechanical updates to improve connector performance. Furthermore, for backward compatibility, modifications and improvements to the physical structure layer are required. Adding a conductive connector at the bottom and short-circuiting the ground terminal improves the consistency of single-ended impedance of signal terminals and reduces differential impedance fluctuations, thereby optimizing and improving performance indicators such as insertion loss, return loss, and crosstalk, meeting association specifications. Currently, the conductive connectors in connectors are generally made of conductive plastic, achieving short-circuiting of the ground terminal through contact between the conductive plastic and the terminal. Because the conductive plastic is integrally injection molded and then assembled to the bottom of the product, there is a risk of contact failure with the ground terminal after assembly, leading to reduced product performance and failure to meet usage requirements.
[0004] Therefore, it is necessary to design a connector to solve the above problems. Summary of the Invention
