Contact assembly

Compression contact apparatus comprising:

• a frame of dielectric material having first and second end walls, a plurality of cavities between said end walls, and a plurality of holes in each end wall, each hole extending into one of said cavities;
• an extendable contact assembly lying in each of a plurality of said cavities, each contact assembly including a pair of probes projecting through holes at opposite ends of a corresponding one of said cavities, and a spring device constructed of dielectric material in said cavity which urges said pair of probes apart;
• said first probe has walls forming a bore with an opening in one end thereof which is closet to second probe, and said second probe having a pin slideably received in said first probe bore;
• said first and second probes each have a flange lying in said cavity, and said spring device lies about said pin and has opposite ends bearing against said flanges.

Compression contact apparatus comprising:

• a frame of dielectric material having first and second end walls, a plurality of cavities between said end walls, and a plurality of holes in each end wall, each hole extending into one of said cavities;
• an extendable contact assembly lying in each of a plurality of said cavities, each contact assembly including a pair of probes projecting through holes at opposite ends of a corresponding one of said cavities, and a spring device constructed of dielectric material in said cavity which urges said pair of probes apart;
• said frame includes a plurality of side enclosures projecting from said second end wall, each side enclosure surrounding one of said contact assemblies, and said side enclosures being spaced apart;
• and including
• conductive material covering the outside of each side enclosure.

Contact apparatus comprising:

• a frame which includes a body having a face and a plurality of cavities extending into said face, and at least one wall structure lying over said face and having a plurality of apertures for passing contacts, said wall structure including a plurality of dielectric bushing portions projecting into said cavities;
• a plurality of contact assemblies, each lying in one of said holes;
• said cavities having walls of electrically conductive material, with the conductive material of said plurality of cavities connected together;
• said body has a predetermined thickness and said cavities extend through the entire thickness of said body, said body having first and second faces;
• said frame includes a second wall structure lying over said second body face and having apertures and having bushing portions projecting into said cavities.
