TE Connectivity Grounding Block | 14 Position Connector Housing

The TE Connectivity 203540-1 Grounding Block is a compact 14-position connector housing designed for aircraft electrical systems requiring multiple wire-to-airframe grounding points. It provides a centralized, low-resistance path for grounding avionics circuits and ensures clean EMI and static discharge control throughout the airframe.

Each ground wire is crimped to a size 16 socket contact and loaded into the 14-position connector housing. The mating connector is then attached to the grounding block, which is securely fastened to the aircraft structure to establish a durable, maintenance-friendly ground reference. Ideal for avionics panels, harness assemblies, and retrofit installations where organized grounding is critical.
