The TE Connectivity 3-828102-1 is a jackscrew socket from the AMPLIMITE HD series, designed as a panel-mount retention accessory for D-sub connectors. The threaded portion below the head measures 0.118" (3.00 mm), sized to pass through standard D-sub panel cutouts and engage the mating screw. This part is used with D-sub front panel mount connectors, providing the mechanical lock that prevents the pair from vibrating loose in industrial or field-service environments where the cable is handled repeatedly.
Thread Size and Panel Fit
The thread configuration is 4-40 Socket, 4-40 Screw — meaning the jackscrew socket has a 4-40 internal thread that accepts a 4-40 male screw, and the external body may also carry 4-40 threads for panel mounting. The 0.118" (3.00 mm) length below head is the distance from the underside of the head to the end of the threaded barrel; this dimension determines the maximum panel thickness the jackscrew can pass through before engaging the mating thread. For a standard D-sub panel thickness of 0.040" to 0.090", this 0.118" length provides adequate thread engagement without bottoming out.
Compatibility and Application
The 3-828102-1 is compatible with D-sub front panel mount connectors — the jackscrew socket replaces the standard screw-lock hardware on the female D-sub shell. It mates with the corresponding 4-40 screw on the male D-sub plug or panel bracket. In a typical harness assembly, the jackscrew socket is inserted from the front of the panel through the D-sub cutout, and the 4-40 screw from the mating connector threads into it, pulling the two shells together. This provides a vibration-resistant connection for applications like industrial control panels, test equipment, and serial communication ports where the D-sub cable is frequently plugged and unplugged.
