1 filter + protective plate
2 sets of hermetically sealed custom connectors
The challenge was to develop smart products with very tight weight and space limitations using a creative engineering approach.
The filter and protection board were designed to implement Transeint protection according to MIL-STD-1275D and MIL-STD-704A&E, and to provide line-to-line and line-to-ground attenuation performance. Additional electronic features, such as reverse polarity protection and undervoltage shutdown, were requested and incorporated. An internal GPS module was added to the board, along with an electronic switch that toggles the GPS signals between internal and external inputs.
The custom connector assembly (male and female) was precisely engineered with a special mechanical shape to fit snugly within the payload sliding ring system. The contact portion was custom-designed to meet the customer's requirements and includes 32 data contacts (size 22), 4 power line contacts (size 20), and one MMCX coaxial contact for the video link. The connectors are hermetically sealed at 105 cc/sec of helium.
The connector assembly is supplied with flexible silicone cables and is rated for hundreds of thousands of rotational cycles within a ±35° range.
