CHAMP .031 Backshell — 36-Position Shielded Cover
The TE Connectivity 787231-1 is a two-piece backshell and cover for the CHAMP.031 connector series, designed to terminate the cable side of a 36-position shielded interconnect. The metal shell (steel) and plastic cover construction gives the assembly its shielding continuity, while the spring lock feature lets you snap the backshell onto the connector without tools — a practical detail for field-service swaps or production-line rework where you don't want to chase a screwdriver.
What the Hardware Tells You About the Build
The 36-position count matches the full-size CHAMP.031 connector — if your harness has fewer circuits, you still use this backshell; the extra cavity just sits empty. The spring lock engages with the mating connector's latch ears, so confirm your CHAMP.031 plug or receptacle has the corresponding lock feature before committing. Shielded construction means the metal shell provides a ground path around the cable braid — critical for signal integrity in noisy environments like industrial control cabinets or data-acquisition panels where the CHAMP.031 series is common. The strain relief clamps down on the round cable jacket, not the individual wires, so the termination points inside the connector don't bear the pull load. Colour is black, which is the standard for the series — no colour-coding option here, so if your harness uses colour for routing identification, you'll need a secondary marker.
