Keeping connectors secure in space

On 4 July 2020, Rocket Lab's Electron rocket experienced a launch failure, leading to the loss of seven satellites. A higher resistance in one connector caused it to heat up, melting the anti-vibration material that covered it. Vibrations then disconnected the joint, cutting the power to the turbopump.

Connectors undergo extreme stresses in all stages of space missions. Here, Alex Raymond, Product Manager at PEI-Genesis, takes us through the different stages of a space
mission to the moon, discussing the challenges that connectors face and what measures manufacturers take to ensure that they withstand such harsh conditions.

The main
engines and rocket boosters ignite with a great roar, and intense vibrations are felt by every component on the spacecraft. These vibrations can impact the integrity
of connectors and their functionality by shaking them apart.

Moreover, rapid temperature and pressure changes during launch can cause some of the materials that seal the connectors
to expand and contract, loosening the contacts and causing faulty connections.

To overcome the launch challenges, connectors must be designed with precision and robustness.
