44-Position High-Density D-Sub Plug Housing for Shielded Harness Assemblies
The TE Connectivity 1658672-1 is a 44-position, 3-row D-Sub high-density plug housing from the AMPLIMITE HDP-22 series. It is the plug half of the D-sub pair, designed to accept male crimp contacts for field-terminated or factory-built cable harnesses.
Shell Size and Mating Half — What Fits
This housing uses shell size 3 (DB, B) in the high-density layout, which is the standard shell for 44-position high-density D-subs. The unthreaded flange on this plug means the mating receptacle should provide the threaded inserts or standoffs for the jackscrews.
Grounding and Shielding — Why the Indents Matter
The grounding indents stamped into the steel shell are the primary path for shield current between the cable braid and the mating connector shell. In a properly assembled shielded cable, the braid is terminated to the shell via a metal backshell or a grounding strap; the indents ensure electrical contact across the mated interface before the signal pins engage. This is the difference between a connector that passes radiated emissions testing and one that does not — the indents are not optional for EMI-critical applications.
