What This Jackscrew Socket Does in a CHAMP Latch Assembly
The TE Connectivity 5553636-2 is a jackscrew socket from the CHAMP Latch series, designed as a hardware accessory for CHAMP Latch D-Sub connectors. It provides the threaded fastening that secures the connector pair against vibration and maintains consistent contact pressure across the interface. The socket carries dual thread standards — an M3.5 socket and a 4-40 screw — so it works with both metric and imperial hardware common in CHAMP Latch backshells and panel mounts. Hardware is included in the bagged kit, which means the socket arrives with the mating screw and any washers needed for installation.
The thread size is the primary selection parameter: M3.5 socket and 4-40 screw. This dual-standard thread lets the socket accept either a metric M3.5 screw or a 4-40 UNC screw, matching the hardware used on the mating CHAMP Latch connector or panel. The length below the head is 0.494" (12.55 mm), and the threaded portion below the head measures 0.318" (8.08 mm). These dimensions govern how far the socket protrudes through the panel or backshell and how much thread engagement the screw gets — critical for a secure, rattle-free assembly in a chassis or enclosure.
Compatibility and Use
This jackscrew socket is intended for use with CHAMP Latch D-Sub connectors. The socket replaces or supplements the standard jackscrew hardware on any CHAMP Latch D-sub that uses the same thread pattern.
