[0002] The existing ultra-high-speed connectors are designed based on the civilian field, and their working process is basically in a static state; while the ultra-high-speed connectors used in the military field are often affected by high vibration and high impact loads during their working process, and the working environment is abnormal Therefore, the ultra-high-speed connectors in the civilian field obviously cannot be used in the military field; and currently there are no ultra-high-speed connector products used in the military field in China

[0003] Traditional military high-speed connectors are formed by putting independent machined circular pins into the fixing holes of the insulator one by one. In this structure of high-speed connector plugs, the pins are independent parts and the overall structure is circular. Cooperating with the matching pin sleeve, the contact reliability is high, and it is suitable for use in occasions with high communication reliability, but it also has the following problems: 1. The pins need to be inserted into the insulator one by one, and the assembly efficiency is extremely low; 2. There is a clearance fit between the pins and the insulator holes, so the spacing between the pins is unstable, resulting in unstable impedance characteristics; 3. The cross-section of the pins is circular, which is not conducive to the coupling of differential signal transmission; 4. The pins are machine Processing parts, high cost; 5. When the same differential pair is a curved pin, the delay difference is too large, and the communication rate cannot be further improved; 6. The consistency of the same batch of products is poor after assembly, and the product performance is unstable; therefore, the existing machined pin structure Generally applicable to communication occasions where the communication rate is below 3.125Gbps

[0004] The pins of the existing civil ultra-high-speed connectors adopt a chip structure, and the matching contacts adopt a chip-type elastic single-side contact structure. One-sided contact, when used in high-vibration and high-impact environments, is prone to the problem of instantaneous separation of contacts, resulting in failure of signal transmission
