At present, more and more radio frequency signals are transmitted between vehicle-mounted circuit boards and are used for interconnecting connectors with a spacing of 3mm, and under normal conditions engineers choose an SSMP connector (minismp, SMPM, GPPO), the typical solution accords with MIL-STD-348A, and FIG. 1 is an SSMP connector standard size, and has the characteristics of small volume, high working frequency, large tolerance range and the like, but the SSMP connector products on the market at present only pay attention to one of the factors of mechanical performance, electrical performance or economic benefit.

1. From the standard dimension, when the distance between the use cases is 3mm and the size of the inner hole of the SSMP connector is 2.92, the thickness of a single side is only 0.04mm, so that the machining difficulty is greatly improved, and the possibility of edge breakage is possibly caused; even if machined, even if the SSMP cable assembly is inserted, even slight shaking can cause unilateral deformation or loosening;

2. with the prevalence of electrical automation equipment, 100 plug lives of SSMP connectors are now far from sufficient, and there is a great need to develop a plug connector to replace SSMP connectors.
