Hermetic edge-connect headers and corresponding connectors
| DWPI Title: Edge-connect header has electrical conductor braze fillers that are located between electrical conductors and core, and slot that exposes machined surface of core and machined surfaces of electrical conductor |
| Abstract: A hermetically-sealed edge-connect header that can withstand high temperatures, high pressures (or high vacuum levels), and high vibration environments, along with two corresponding connectors are disclosed. After brazing the edge-connect header components, the assembly is machined to form a slot with a portion of each of a plurality of electrical conductors removed in the machining process, resulting in a header with a high pin density. During the process of mating the first connector design to the edge-connect header, a plurality of wipers in the connector deflect, thereby causing the wipers to extend from the connector and contact the corresponding electrical conductors in the header. During the process of mating the second connector design to the edge-connect header, each of a plurality of wipers formed of low-mass, compliant metal wool, forms multiple contact points with a corresponding electrical conductor in the header. |
| Use: Edge-connect header. |
| Advantage: The hermetically-sealed edge-connect header withstands high temperatures, high pressures and high vibration environments. The supported header pins are loaded by the connector wipers upon the final stage of mating or through a low-mass, compliant metal wool to reduce electrical chatter and wear during repeated mating and de-mating |
| Novelty: The edge-connect header (100) has a housing (110) and a core (120) located within an opening in the housing. A core braze filler is located between the housing and the core. The core braze filler is adapted to form a first hermetic seal. Several electrical conductors (130) are located within one of the openings (150) within the core. The electrical conductors include a first set and a second set of the electrical conductors. The electrical conductor braze fillers are located between the electrical conductors and the core. The electrical conductor braze fillers are adapted to form a corresponding second hermetic seals. A slot exposes a machined surface of the core and the machined surfaces of the electrical conductors. The slot is a linear slot. The first set of the electrical conductors are located adjacent a first side of the linear slot. The second set of the electrical conductors are located adjacent a second side of the linear slot facing the first side of the linear slot. |
