The traditional military high-speed connector is formed by loading independent machined circular pins into fixing holes of an insulator one by one, and the pin of the high-speed connector plug with the structure is an independent part and has a circular integral structure, is matched with a matched pin sleeve, has high contact reliability, is suitable for occasions with high communication reliability, and has the following problems: 1. the contact pins need to be arranged in the insulators one by one, and the assembly efficiency is extremely low; 2. the contact pins and the insulator holes are in clearance fit, so that the distance between the contact pins is unstable, and the impedance characteristic is unstable; 3. the cross section of the contact pin is circular, which is not beneficial to the coupling of differential signal transmission; 4. the contact pin is a machined part, so that the cost is high; 5. the time delay difference is too large when the same differential pair is a bent pin, so that the communication speed cannot be further improved; 6. the consistency of the same batch of products after assembly is poor, and the product performance is unstable; therefore, the existing machined pin structure is generally suitable for communication occasions with communication speed of less than 3.125 Gbps.
The contact pin of the existing civil ultrahigh-speed connector adopts a sheet type structure, and the contact element matched with the contact pin adopts a sheet type elastic unilateral contact structure, so that the structure has the advantage of easily realizing ultrahigh-speed data transmission, but because the matched contact element is unilateral contact, the instant separation problem of the contact element is easily generated when the connector is applied to high-vibration and high-impact environments, and the signal transmission failure is caused.
Therefore, in order to realize a military connector with low cost, high speed, high density and high reliability, the existing connector structure must be newly developed and designed.
