Description

SSMP connector of intensive installation

Technical Field

The utility model relates to an SSMP connector installed densely, and belongs to the technical field of connectors.

Background

With the development of new generation weapons and carrying system technology, especially the development of high-speed and ultra-high-speed cruise missiles and large-carrying-capacity rockets, the whole system is required to be small in size, light in weight and wide in frequency band. The SSMP connector is widely used in modular densely packed applications because of its small size, light weight, wide frequency bandwidth, and multiple interface formats to meet the axial float and radial misalignment required for blind mating.

Due to the fact that the use requirements of different use occasions on the connectors are different, the ultra-small SSMP is required to be densely installed at one end, a cable assembly of a connector with a larger size relative to the SSMP is required to be used at the other end, and if the large connector is required to pass through an installation hole of the SSMP during installation, the small-distance dense installation cannot be achieved at the end of the SSMP. If the mounting hole is only installed from the SSMP end, a positioning step with a size larger than that of the mounting hole is required to be arranged on the SSMP shell for positioning during installation, and the reduction of the installation distance is limited by the arrangement of the positioning step. Against this background, there is a great need for a connector that is reliably positioned and does not fit into mounting holes to meet the requirements of modular dense installations.
